@KSA_MissionCtrl
we've also placed another order for K2-X engines. This latest Ascension Mk3 mission has shown we want to move faster than planned to the Mk4 so the thrust vector control version of the WildCat-V will begin development immediately and we will order more when that is ready
Kerbal Space Agency
@KSA_MissionCtrl
a final round of static fires last week has completed the WildCat-V's second qualification run & we'll know for sure by next month if it is finally ready for production. If so, two will be ready by Q3 2021 for Extremis I and a Min/Minmus mission
Kerbal Space Agency
@KSA_MissionCtrl
the Viklun upper stage will be systematically dismantled to help determine the cause of the flexing and what effect it had on the overall structural integrity of the rocket. The damage from splashdown will reduce these findings but hopefully the effort will still prove valuable
Kerbal Space Agency
@KSA_MissionCtrl
onboard vid shows the pitch oscillations during the Ascension Mk3's ascent were way worse than we imagined - the *entire rocket flexed* 😱 inherent structural issue? Could also be from the air pressure at the nose (think boat bow slamming up & down on hvy seas) from shallow angle
Kerbal Space Agency
@KSA_MissionCtrl
when the Viklun stage splashed down the empty fuel tanks blew out, helping to alleviate impact pressure on the payload but fragments pierced the flight computer & damaged the flash memory. Onboard tlm data was lost but the ops log final mins were able to be pieced back together
Kerbal Space Agency
@KSA_MissionCtrl
some Ascension Mk2 bit.ly/KSARecords have now been claimed by the Mk3:
(previous record)
Heaviest Rocket Launched, Minus Payload: 19.862t (17.5t)
Heaviest Payload Launched, Orbital Trajectory: 1.662t (767kg)
Tallest Rocket Launched: 16.782m (16.212m)
(previous record)
Heaviest Rocket Launched, Minus Payload: 19.862t (17.5t)
Heaviest Payload Launched, Orbital Trajectory: 1.662t (767kg)
Tallest Rocket Launched: 16.782m (16.212m)
Kerbal Space Agency
@KSA_MissionCtrl
at this time we do not know the nature of the threat or the time frame, but given that we have suffered an attack in the past (kerbalspace.agency/?p=9965) we have no choice but to take this seriously & deal with the relatively minor inconvenience compared to a potential loss of life
Kerbal Space Agency
@KSA_MissionCtrl
there is also now apparently a threat against KSC and we have complied with orders from the government security forces earlier today that the entire facility be evacuated. We will continue to operate at limited capacity from our HQ in Umbarg until the threat has passed
Kerbal Space Agency
@KSA_MissionCtrl
the original plan to develop a 1.25m TVC vacuum engine was put on hold to instead work on the 1m vac engine suitable for payloads and also because our experience with the Progeny Mk7 made us want to get more TVC engineering data from the Mk8 for a fully TVC Ascension Mk4 by 2022
Kerbal Space Agency
@KSA_MissionCtrl
in putting together the Ascension Mk3 mission report timeline (kerbalspace.agency/?p=11619), since it is the first, we go all the way back thru the rocket's development as well. That reminded us of this tweet outlining the Mk3's design goals. What happened to the TVC vacuum engine?
Kerbal Space Agency
@KSA_MissionCtrl
the Viklun stage & Kerbin III have been transported via rail back to KSC after arriving in port at Umbarg on Sunday. We still have to confirm that Kerbin III remains fit for flight but visual inspection looks good. Entire Viklun stage will need to be rebuilt but that was expected
Kerbal Space Agency
@KSA_MissionCtrl
we are working on a full launch video but here is a look at initial ascent and booster drop from the ground tracking cam atop the Tracking Station & cam atop the crew tower. Bonus to upper-stage recovery is that we will get high FPS video from the booster camera for once!
Kerbal Space Agency
@KSA_MissionCtrl
our crew did not miss the launch and are excited to one day ride this rocket up into orbit. Several years ago they didn't know for sure if they'd even get to take a ride up into space yet! The final frontier is broadening bit by bit...
Kerbal Space Agency
@KSA_MissionCtrl
until we are able to examine the upper stage there remains a chance that some assembly error led to the abort but we more than likely simply exceeded the capabilities of the rocket. So had we launched on the original date the outcome would have likely been for the same reasons
Kerbal Space Agency
@KSA_MissionCtrl
telemetry from yesterday's flight is now available: docs.google.com/spreadsheets/d… we will fill in the missing final minutes once we can recover the data from the flash memory aboard the Viklun stage after it returns to KSC
Kerbal Space Agency
@KSA_MissionCtrl
post-launch operations wrapping up with the final booster heading back to the VAB where it will be inspected with the others before being shipped back to Periapsis Co. in Umbarg for refurbishment. Rocket should be back at KSC by Tuesday
Kerbal Space Agency
@KSA_MissionCtrl
ultimately of course this mission will be marked as another failure but like our last one in January it's not a total loss as we have collected valuable data which will be put to good use planning for future missions, including the re-flight of Kerbin III
Kerbal Space Agency
@KSA_MissionCtrl
we're relaying through 2 other ships but have received the message that MSV Aldeny has found the rocket intact! Viklun stage suffered heavy damage as expected but Kerbin III is looking in good shape. Great to hear the best worst case scenario for this mission has been achieved
Kerbal Space Agency
@KSA_MissionCtrl
the Aldeny is about 1.5-2hrs away from the rocket's last known position but should already be underway at best possible speed & sea conditions were reportedly good in the area. Meanwhile, all 4 boosters confirmed down intact & are being towed back to shore one at a time
Kerbal Space Agency
@KSA_MissionCtrl
we won't know the fate of the rocket until we hear from MSV Aldeny on the VHF radio, but we do know it was in the best possible configuration for a successful splashdown when we lost contact, so that is reassuring. It will hit hard, but Viklun stage will soak up most of impact
Kerbal Space Agency
@KSA_MissionCtrl
there was some success in slowing down, although late in the final moments of the burn the stage tumbled further out of control than expected and actually started to gain velocity again! But SECO arrived shortly and upper stage is now nearing terminal velocity anyways
Kerbal Space Agency
@KSA_MissionCtrl
upper stage continues to fight air pressure and orient retrograde. If you see the throttle go wide open than the orientation was successful. If it falls back to 50% it was unable to be held & will keep trying. This reduction in velocity will prevent excess heating as it falls
Kerbal Space Agency
@KSA_MissionCtrl
ABORT! ABORT! ABORT! A tumbling upper stage was unable to show signs of recovery and the ascent has been terminated. Viklun ignition was good so the RCS is attempting to re-orient the vessel retrograde while the engine is in low-thrust mode so velocity can be reduced
Kerbal Space Agency
@KSA_MissionCtrl
as expected some very minor deviation in roll/hdg but not enough to exceed constraints. We are however seeing very bad pitch oscillations, which is new behavior not experience by any previous rocket. This does not bode well but hopefully ride smooths out with finless upper stage
Kerbal Space Agency
@KSA_MissionCtrl
initial ascent showed the rocket already had some issues keeping pace with the required pitch over rate but eventually caught up & returned to nominal. It is now supersonic tho & we expect fin flutter will make it exceed its tight constraints so flashing red may not be *too* bad
Kerbal Space Agency
@KSA_MissionCtrl
good main engine ignition, booster ignition and LIFT OFF! The first flight of the Ascension Mk3 soars up into the sky to carry the Kerbin III probe up into orbit so it can perform a long-term study of the radiation belts. Launch thrust is 306kN for a TWR of 1.45
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] tune into the Ops Tracker now if not already! ops.kerbalspace.agency live ascent telemetry will load after 30s final poll if all goes well. "Hold hold hold!" is not a call we want to hear at any point over this next minute, but it could happen. Final launch sequence:
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] terminal count! Automated Flight Control System has taken over control of the rocket, service towers have detached to leave rocket on internal power & RF comms. Dual flight computers are performing synchronization and SRB hold-down bolt explosives are armed
Kerbal Space Agency
@KSA_MissionCtrl
[L-4m] Viklun tanks pressures still climbing but have reached levels to help improve upper stage rigidity after service tower retracts. Lower stage is held firm by its boosters but upper stage is more susceptible to strong wind gusts
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] Wx? GO! Range? GO! Tracking? GO! Payload? GO! Flight? GO! Ops Director @DKerman_KSA has given permission to launch - 🚀 GO ASCENSION! GO KERBIN III! 🚀 FTS internal, service towers unlocked for retraction at terminal count when AFCS startup begins
Kerbal Space Agency
@KSA_MissionCtrl
ascent needs to be very tight to put the rocket where we planned for it to go but fin steering likely to exceed these constraints often. So a bit of flashing red during ascent telemetry is to be expected, but a lot of extended red for these & other values will not be a good sign
Kerbal Space Agency
@KSA_MissionCtrl
[L-13m] late onload of nitrogen gas for pressurizing the Viklun stage is now underway and helps to ensure pad crew safety in the event of a tank rupture. The gas will help to ensure engine restart for SES-2 & SES-3, any additional restarts will use the engine's orbital tanks
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] RSO has confirmed range clear & closed, engines are ARMED and Flight Termination System is ACTIVE. Spectator areas are packed but do not move outside designated locations. Final check underway by safety officers that all outside are wearing hearing protection
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] weather remains GO for final countdown procedures to begin. Any further holds from this point will likely scrub the launch as we are aiming to put our apokee opposite the sun so launch window is near-instantaneous. MLP is secured & pad crews withdrawn to a safe distance
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h] launch controllers have settled in to rehearse the 3m38s ascent with their consoles being fed simulated data to ensure that everyone knows their roles and that systems are properly configured. This is done a few times with FD Lanalye sometimes throwing in some failures
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h35m] KerBalloon has been released to carry its instrument package aloft for some updated upper-level wind data in addition to confirming the earlier surface conditions forecast. It will reach the upper atmosphere (18km+) in ~1hr & climb as high as 25km
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h45m] FD Lanalye confirms rocket is ready to go as preflight concludes. Countdown continues! Range Safety Officer now working to ensure waters and airspace along launch corridor remain clear. Our booster recovery boat has been launched into the bay north of KSC
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h40m] all is looking nominal as we move into checks of the engine & ignition systems. Pad crew clearing back to a safe distance. Small electrical charges sent to igniters to confirm continuity should not light anything off but always better safe than sorry
Kerbal Space Agency
@KSA_MissionCtrl
leaving port from Umbarg earlier this week, MSV Aldeny is still on station ~225km downrange to handle recovery in the event of an ascent abort. It is near enough to the shipping route between Sheltered Rock & Umbarg that we can pass messages back and forth via maritime captains
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h20m] wakey wakey! Flight computers booting up aboard the Viklun & Kerbin III. Kerbin III will power back off after initial checks & stay asleep until orbit, Viklun's dual computers will command the ascent. Pad workers are out at the rocket to prep the physical flight systems
Kerbal Space Agency
@KSA_MissionCtrl
given the variable nature of ascent trajectories we will probably just have 4 thrusters on both sides moving forward. It really is a bit of an overly-prudent measure to just not have 2 extra thrusters, although of course CFO Mortimer would disagree...
Kerbal Space Agency
@KSA_MissionCtrl
something easily overlooked about the Mk3 design for this flight in particular is the placement of the RCS pitch thrusters. For Mk2 concern was heavy nose falling down, Mk3 concern is air pressure pushing nose up, so more thrusters are there to help push it down
Kerbal Space Agency
@KSA_MissionCtrl
[L-5h] although the A team of launch controllers is just as prepared as they were earlier this week, sticking to the timeline is important for protocol & FD Lanalye is making it clear no changes have been made to the original flight plan: twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
[L-5h25m] weather conditions have improved and an 85% favorable forecast was delivered by Kat's team of meteorologists so we are GO to once again begin gearing up for launch preparations across campus. Condensed timeline of major events is as follows

if you missed anything important these past two weeks that is not Ascension Mk3 related you can find more info on these events in our Ops Summary, including Ascension Mk3 info. If weather cooperates, prelaunch will kick off tomorrow @ 13:38 UTC! kerbalspace.agency/?p=11606
Kerbal Space Agency
@KSA_MissionCtrl
the extended launch delay has left a fully-tanked 21ton rocket sitting atop the MLP and although it is *designed* to handle rockets much larger than the MK3 Lead Engineer Simon still has a crew regularly checking the load bearing elements for any signs of distress
Kerbal Space Agency
@KSA_MissionCtrl
a lot has changed since the last time we happened to have a rocket out on the pad during a sunrise eclipse! Taken during first sunrise earlier today. We've had more success than failure launching during eclipses so if this were still a launch day we wouldn't have been too worried
Kerbal Space Agency
@KSA_MissionCtrl
[L-5h25m] launch forecast is 35% favorable & we have decided to delay until tmrw. Launch window is very small so setting up and waiting for weather to maybe improve isn't worth it. Yes it's a wknd but we need the MLP for Progeny Mk8 so any further delays will also push that back
Kerbal Space Agency
@KSA_MissionCtrl
new cables have been run, Kerbin III still comfy inside its fairings and rocket remains tanked so we can condense our countdown tomorrow. Hopefully now all issues have been taken care of! Prelaunch operations will kick off again at 13:35 UTC for new L-0 of 19:00 UTC
Kerbal Space Agency
@KSA_MissionCtrl
further troubleshooting has revealed old ground cabling is likely corrupting data. We will scrub today to replace them all. Sensor data over RF is as expected, but we need corroboration from two sources. Also, pretty crazy to think that we have old launch equipment!
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h45m][HOLD] an issue that came up since the last milestone has not been cleared & countdown is on a hold now while we continue to work the problem. Sensor data from the engine is not reading as expected - but is the problem on the rocket, the console or somewhere in between?
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h40m] pad crew clearing out so controllers can move into engine & ignition checks. Issues board remains clear and Lead Engineer Simon is pleased to report that the GSE problems from last week's WDR have not recurred either
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h45m] tanking completed on schedule, pad crews moving back in to clean up and move off the truck while controllers can now continue with their preflight checks. Vehicle state changes like this are shown via the Ops Tracker: ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h25m] tanker truck is hooked to the service towers and is GO to onload 810/990u LF/O - 9t of propellants between the 1st(7t) & 2nd(2t) stages. Kerbin III was fueled prior to being encapsulated & is only attached to the service towers for power, comms & environmental control
Kerbal Space Agency
@KSA_MissionCtrl
[L-5h] controllers are on console to begin waking up the Viklun flight computer and placing Kerbin III on standby as pad workers clamber all about the MLP removing flight safety hardware. Latest updates to the AFCS can be found here: github.com/KSAMissionCtrl…
Kerbal Space Agency
@KSA_MissionCtrl
yet another reason for pushing the envelope is determining the rocket's limitations, which still can't be modeled to a high-degree. Yes the rocket could fail, but it will do so under the best case conditions for not losing the entire mission in the process
Kerbal Space Agency
@KSA_MissionCtrl
the main factor in the Mk2's failure was inadequate attitude control. Mk3 not only has more powerful RCS but greater torque force due to its longer body. Fairings will also still be attached when 2nd stage starts off on its own to help with aerodynamic stability & heating
Kerbal Space Agency
@KSA_MissionCtrl
although the ascent is risky, it gives the mission the best insertion apokee with the most fuel remaining, so it is worth going for. Also, Kerbin III is designed to be recoverable, which means it can abort the ascent if needed and return the entire upper stage with a splashdown
Kerbal Space Agency
@KSA_MissionCtrl
[L-5h40m] Flight Director Lanalye has assembled her A team of launch controllers for final preflight briefing. Here is all you need to know about today's planned ascent, which will actually be more aggressive than the Mk2 that failed just over a year ago: ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
[L-6h5m] our small team of meteorologists led by Katgan have given the GO for prelaunch procedures to commence, with a 90% favorable forecast for this day cycle. Teams continue to organize & deploy across campus, expect updates at these milestones in the countdown

Kerbin III is healthy & checked out, all launch readiness reviews have been approved by @DKerman_KSA so we are GO for the Ascension Mk3's first launch attempt! Increased length of pre-launch procedures means things will get started early tomorrow at 11:09 UTC
Kerbal Space Agency
@KSA_MissionCtrl
our crew are training hard every day with barely any free time but unlike past launches where they've worked it into their sched as available they are making sure not to miss this one despite delays. They are psyched to see their future ride head to space! twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
Kerbin III final integration went smoothly this week: RTG was installed & payload encapsulated in its fairings then mounted atop the Ascension Mk3 stack, which is now rolling back towards the pad so Kerbin III can be powered on and undergo testing to ensure launch readiness
Kerbal Space Agency
@KSA_MissionCtrl
CFO Mortimer has finally been able to post our first financial report for 2021 covering the month of January. Commercial success this year hinges on the Ascension Mk3 & Progeny Mk8 being able to accept contracts, from which we can extract profit: docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
Flight Director Lanalye has informed us she noticed we posted an incorrect time for the 2/11 Ascension Mk3 launch, which is supposed to be at 18:57 UTC. We're not sure where the miscommunication occurred but Ops Tracker now has the proper time, we apologize for the error
Kerbal Space Agency
@KSA_MissionCtrl
vertical test stand is once again hosting the WildCat-V as it begins its second round of qualification testing. Unlike previous engines, this one will not fly afterwards. If all is well though we will have new ones in time for the second Ascension Mk3 mission later this year
Kerbal Space Agency
@KSA_MissionCtrl
a full investigation into the destruction of CFO Mortimer's computer has shown it was indeed bad electrical wiring and it looks like the problems that have been affecting the Admin Bldg for a while now will require some serious overhaul, tho no effect to ongoing operations
Kerbal Space Agency
@KSA_MissionCtrl
being that this is a highly-anticipated mission it was scheduled to get up into space ASAP but looks like we were being a bit too ambitious on our timeline. A few days delay is worth it to ensure that months of preparation are not wasted by a rushed deployment leading to failure
Kerbal Space Agency
@KSA_MissionCtrl
we are now targeting 2/11 @ 17:14 UTC for launch of Kerbin III atop the Ascension Mk3 to allow the VAB more time to prepare the payload after crew members informed Lead Engineer Simon that they felt overworked and stressed to complete the vehicle on time for launch
Kerbal Space Agency
@KSA_MissionCtrl
report from Lead Engineer Simon on today's wet dress rehearsal is that all went successfully but not without issues. He and his team will be working over the weekend to ensure that the delays experienced today will not affect the countdown next week
Kerbal Space Agency
@KSA_MissionCtrl
rolling! Mobile Launch Platform carrying the Ascension Mk3 is making its slow way out to the pad. It will be hooked up to the service towers and tanked to ensure it can handle the fuel load, no leaks are present, ground support equipment is functioning properly, etc etc.
Kerbal Space Agency
@KSA_MissionCtrl
the process that began last week with the lift stage being stacked atop the MLP has completed with the Viklun orbital stage now mated to the stack. Load checks are now underway while work shifts to securing the entire rocket for the MLP to move out to the pad later this week
Kerbal Space Agency
@KSA_MissionCtrl
as confident as we feel about getting a kerbal up into orbit this year, it helps to remember that we first said we were going to make it happen almost 2 years ago now. Space is challenging and despite setbacks (Mk1 not being able to make orbit) we push on! twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
a bunch of stats about the career of the Progeny Mk6 and more details from these past two weeks await you in our Ops Summary: kerbalspace.agency/?p=11574 we hope everyone enjoys their weekend!
Kerbal Space Agency
@KSA_MissionCtrl
kerzzah! ✨🥂 A happy 15th kerbolar anniversary to us all here at the KSA. Yes, in the time since the Agency has started operations we have traveled around Kerbol 15 times now for a total distance of 1,280,470,886km! Which sounds impressive but is barely over 1 light hour
Kerbal Space Agency
@KSA_MissionCtrl
the fuel from this RTG will be re-used in future probes. Although as it ages it will slowly lose power, more than enough remains for smaller missions that don't have as much energy requirements. Some will be sent out never to return, some will still be re-used a few more times
Kerbal Space Agency
@KSA_MissionCtrl
MSV Aldeny has pulled back into port at Arekibo after nearly exhausting its supplies again but didn't because it found and recovered the RTG from Kerbin II! \[0_o]/ Not only is it nice to not have it potentially polluting the environment, these things are *really* expensive
Kerbal Space Agency
@KSA_MissionCtrl
the stacking begins! Over this next week the Ascension Mk3 will undergo vertical integration atop the Mobile Launch Platform. The orbital stage is finishing up its build to go on next followed by the payload - although this final stacking will occur after a Wet Dress Rehearsal
Kerbal Space Agency
@KSA_MissionCtrl
Mk1-B capsule testing has concluded and it is now in the VAB for a final structural check. After that careful inspection it will get stripped down on the inside and outfitted with all the sensors and equipment needed for its sub-orbital test flight in March
Kerbal Space Agency
@KSA_MissionCtrl
initial WildCat-V static fires showed good data, but we said that last time too. While analysis is ongoing it will be replaced on the vertical test stand with the Progeny Mk8 cluster outfitted with all 7 engines for the final round of tests. All these engines will fly the 1st Mk8
Kerbal Space Agency
@KSA_MissionCtrl
Kerbin III has arrived from our payload processing facility in Umbarg to be mated with its truss then encapsulated in its fairing. Right before that happens the RTG will be installed. To leave it buttoned up too long would cause the insides to get so hot it would damage things
Kerbal Space Agency
@KSA_MissionCtrl
we've started static firing of the WildCat-V production article this week. It was first tested back in mid-2020 and needed some redesign work that has delayed its deployment, which is why the Ascension Mk3 going up next month is being lifted by a K2-X main engine
Kerbal Space Agency
@KSA_MissionCtrl
it's time for our first Ops Summary of 2021 - are we two weeks into the new year already?? Learn more about what is in store for the first quarter of this year that will set the stage for the remainder of our planned operations - kerbalspace.agency/?p=11531
Kerbal Space Agency
@KSA_MissionCtrl
here is a closer look at the Kerbin III payload that will ride to space next month atop the Ascension Mk3. Full res on flickr (flickr.com/gp/kerbal_spac…). There are some changes to the original design posted late last year, additional images have more information
Kerbal Space Agency
@KSA_MissionCtrl
with several successful test runs completed over the past two weeks firing 5 clustered Skeeter engines we are ready to move up to a full complement of 7. While the reconfig is underway the WildCat-V will take a turn on the stand to begin its qualification trials
Kerbal Space Agency
@KSA_MissionCtrl
the VAB is hard at work getting the Ascension Mk3 ready for her debut flight next month. Solids are getting strapped on! These will all be new boosters. The Viklun stage is still under assembly waiting on its engine & the Mk1 has been mated with its K2-X lifter
Kerbal Space Agency
@KSA_MissionCtrl
Q1 launch schedule now filled - save the dates! Additional info via our bit.ly/KSA_Programs page on the website (now with entries for the Mk3 & 8) or the bit.ly/Ops_Tracker. The Mk3, 1 & 8 missions are all pivotal in deciding how we move forward the rest of the year!
Kerbal Space Agency
@KSA_MissionCtrl
#OTD in 2019 we determined that our options were wide open for whether to visit Mun or Minmus first (with an unkerbed vessel). If the Ascension Mk3 & Kerbin III's performances are as good as expected, we could very well just take on both with a single mission - later this year!
Kerbal Space Agency
@KSA_MissionCtrl

@KSA_MissionCtrl
all our crew returned to duty yesterday, today they get right back into general training with the Mk1-B capsule & simulator as well as physical regimen, medical testing & centrifuge runs. These activities will be carried out over the next 2-3 months before mission training begins
Kerbal Space Agency
@KSA_MissionCtrl
two possible additions are an air traffic control tower if commercial aircraft increases and a larger launch/mission control building if we succeed at increasing our number of long-term orbital missions, which won't all be able operate out of the Tracking Station
Kerbal Space Agency
@KSA_MissionCtrl
all staff and crew are due back at KSC today to begin our 2021 operational year! Here's the new photo that adorns our various social media profiles and website header. This year the only changes planned so far are to expand the Support Village for more on-campus housing
Kerbal Space Agency
@KSA_MissionCtrl
and a look at the various trajectories the vessels took. With the loss of power & loss of position data the Kerbin I Viklun stage decay is a best-guess. Also the Kerbin II Viklun stage was de-orbited in a similar manner to that depicted for Kerbin II, both shared the same orbit
Kerbal Space Agency
@KSA_MissionCtrl
the year may be done but the week is not and we still have one more aspect of our 2020 operations to review - orbital! For the first time we get to look at some stats from missions that circled the planet multiple times, something we plan to do a lot more often in 2021 💫
Kerbal Space Agency
@KSA_MissionCtrl
the Mk7-B helped qualify the reusable boosters for the upcoming Ascension Mk3 as well as paving the way for the Progeny Mk8 with thrust vector control guidance. Ironically our Progeny Mk6 missions, technically the easiest, did not fare well
Kerbal Space Agency
@KSA_MissionCtrl
even though overall launch count was down from last year, the missions were much more complex, including our first ever orbital missions launched from the Ascension Mk2 and getting the rest of our crew up into space via the Mk1. Lots of failures means we learned a lot as well
Kerbal Space Agency
@KSA_MissionCtrl
although we did have a shutdown of the rocketry programs early this year, there was no shutdown of the entire Agency at any point and we at least got off one mission each month in 2020, continuing the streak that went through 2019 as well. Planning to keep it alive in 2021!

our 1st WildCat-V engine has arrived for qualification trials to begin next month during the period we'll be adding two final engines to the Progeny Mk8 cluster, freeing up the vertical test stand. We hope to certify it ready for flight by March if no troubles present themselves
Kerbal Space Agency
@KSA_MissionCtrl
although we signed our biggest commercial contract to date this month to set us high on income for the year, lots and lots of spending to come in 2021. Wernher von Kerman, R&D Head, is excited to have had his full budget proposal accepted, for once

@KSA_MissionCtrl
last year our crew logged a combined 30 missions, down from 56 the year before - such is the amount of time that has needed to be put into training for space flight! With Genesis shut down, all crew are now focused solely on orbital flight in 2021. Lots more training to go...
Kerbal Space Agency
@KSA_MissionCtrl
project and program leads as well as KSA admin staff are back to work already, foregoing the normal 2wk vacay to get working on solidifying plans for next year. We will also be doing our regular recaps on the year's operations over this coming week leading into 2021
Kerbal Space Agency
@KSA_MissionCtrl
our final Ops Summary for 2020 has been published! What an amazing year it has been, despite our troubles towards the end. Thank you everyone for your support, have a safe holiday season and we hope you too are aiming high for 2021! kerbalspace.agency/?p=11442
Kerbal Space Agency
@KSA_MissionCtrl
very quiet at KSC today as everyone mostly ready to head home for new year vacation over the next two weeks. 2021 is looking so busy however Admin staff have agreed to come back in after only a week to begin prepping for operations to resume with vigor on Jan 4th

VAB has received all the remaining parts for the Ascension Mk3's lifter & orbital stages. Lead Engineer Simon says the teams are getting them laid out, prepped and are eager to start the assembly process next month for launch in early Feb
Kerbal Space Agency
@KSA_MissionCtrl
consider that 47m/s is well within error margins for ascent modeling of a new rocket, going straight up not nearly as efficient as a proper launch trajectory and Extremis I is planned be on top of a Mk3 with the more powerful WildCat-V engine. Interplanetary here we come!! 🚀✨
Kerbal Space Agency
@KSA_MissionCtrl
also good news on the initial modeling of a straight-up launch for the Ascension Mk3 with a K2-X engine and the Kerbin III probe firing as well - it almost escapes Kerbin SOI! Altho only halfway, from that point just ~47m/s Δv needed to barely break free of Kerbin's influence
Kerbal Space Agency
@KSA_MissionCtrl
here's a first look at Kerbin III, with notes on its design and mission objectives. Final blueprint coming in Jan after any adjustments made based on Kerbin II recovery. Most of this design is final though and has already started assembly to meet the launch target of early Feb
Kerbal Space Agency
@KSA_MissionCtrl
CFO Mortimer reports contract negotiations have concluded with telecom conglomerate CommStar to pay for the 3 communications satellites that will be deployed by the Ascension Mk3 in mid-2021. Initial payment will cover rocket production, sat design to be finalized by March
Kerbal Space Agency
@KSA_MissionCtrl
the hatch on top allows for a secondary escape path if the main hatch gets stuck or opening it would take on water. Finally the corrugated paneling will better resist the heat of longer, shallower re-entry from orbit to allow us to reduce Gs on the crew
Kerbal Space Agency
@KSA_MissionCtrl
the flatter bottom will conform less to the heat shield but also leave more room for a set of airbags that can deploy to assist with emergency landings on terrain. These are in addition to the flotation collar already used on the Mk1-A for normal splashdowns
Kerbal Space Agency
@KSA_MissionCtrl
here is a closer look at the Mk1-B capsule that will fly atop the Ascension Mk3 to carry crew in LKO. It has more internal volume than the Mk1-A to accommodate expanded ECLSS to support the onboard astronaut properly on longer orbital missions. Also a slightly bigger window
Kerbal Space Agency
@KSA_MissionCtrl
of course the new knowledge also raises concerns regarding such events and the impact they may have on spacecraft and even surface colonies - we won't know more until a similar event occurs or until we get more instruments observing the sun, both on the ground & in space
Kerbal Space Agency
@KSA_MissionCtrl
#OTD 2017 we were still mystified by this occurrence but now we have a better understanding thanks to the discovery of the radiation belts and how they interact with our atmosphere in conjunction with the kerbolar wind as a result of activity on the surface of our sun
Kerbal Space Agency
@KSA_MissionCtrl
CFO Mortimer has updated our financial sheet with Nov's earnings - or lack thereof as expected. Commercial rocket contracts are on the horizon though! Net profit in 2021? More like '22-23 perhaps. But next year would be nice... docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
next year the Ascension Mk3 will be placing 3 commsats into orbits similar to Kerbin II but spaced so when one sets, another will rise to take its place in the sky and enable continuous communication from almost anywhere on Kerbin's surface - latitudes above 75° will be excluded
Kerbal Space Agency
@KSA_MissionCtrl
as you can see, Kerbin II does travel away from the expedition site & is not able to communicate every pass. In general the ground teams have 5-8 mins during 5 windows ~35min apart, then a ~3hr wait for the start of the next 5-window pass
Kerbal Space Agency
@KSA_MissionCtrl
coming up on a Kerbin II contact window with the expedition the KerBalloon crews are attached to, which will bounce a signal to DSN Central that will be distributed via ground cables to the command centers here at KSC and Sheltered Rock where the science expedition is based from
Kerbal Space Agency
@KSA_MissionCtrl
we just concluded a static fire test of the Boosterton II that flew the final Mk7-B mission last month, making this the 3rd time it's been fired after two flights. Still lots of post-test analysis to do but it survived! Next month it will earn a place in our Rocket Garden
Kerbal Space Agency
@KSA_MissionCtrl
plenty of exciting things to recount & expound upon from these past 2wks, so be sure to check our Ops Summary this weekend while you are kicking back to relax - at least we hope you are! What are your plans? Our crew will be off on a wilderness excursion kerbalspace.agency/?p=11398
Kerbal Space Agency
@KSA_MissionCtrl
the engine comes with pressurized LF/O tanks to allow 6 restarts, after which cold gas will need to be used to pressurize any main tanks. Each restart will require a bit more gas & not all will be recovered afterwards so it will begin to have an affect on mission longevity
Kerbal Space Agency
@KSA_MissionCtrl
we've awarded a contract to Rockomax, to build a LF/O vacuum-optimized engine to be fitted on probes launched by the Ascension Mk3. 1st test will be on Kerbin III in early 2021. The engine will support interplanetary missions & Kerbin missions needing flexible trajectories
Kerbal Space Agency
@KSA_MissionCtrl
while the guidance fins are restricted early in flight due to the radial decouplers, if needed the RCS thrusters can be used to help with pitch-over and roll. SRB re-use will have only minor impact on costs but that is not the point - it is just progress towards full reusablilty
Kerbal Space Agency
@KSA_MissionCtrl
other than WC-V engine, the Mk3 is comprised of flight-proven hardware from the Mk1, Mk2 and Progeny Mk7-B. With the K2-X powering at least the first 2 missions we have the confidence to send up actual payloads right away, starting with Kerbin III - more details later this week!
Kerbal Space Agency
@KSA_MissionCtrl
although we plan to have the WildCat-V flight-certified by end of Q2 2021, the Mk3 will initially launch with the K2-X, of which 2 are currently available. 3 more have also been ordered just in case issues arise with the WildCat-V during testing. 1st WC-V arrives next month
Kerbal Space Agency
@KSA_MissionCtrl
the Ascension Mk3 is looking 🤩 and has been finalized for preparation to begin launches in early 2021! It will carry probes to Mun, Minmus and even beyond the Kerbin system. It will carry crew into Low-Kerbin Orbit. Full resolution: flickr.com/gp/kerbal_spac…
Kerbal Space Agency
@KSA_MissionCtrl
second change was the addition of a cold gas tank between the LF/O tanks. Not only does this add more RCS fuel for maneuvering but also raises the center of mass, which means the pitch thrusters on the bottom now have more torque to be even more effective in attitude control
Kerbal Space Agency
@KSA_MissionCtrl
2 design tweaks made to the Mk3 since the first render. First change is to the SRB placement, which are higher up now in order to allow the rocket to be properly mounted on the Mobile Launch Platform and align with the service tower linkups for fuel, power and ECLSS
Kerbal Space Agency
@KSA_MissionCtrl
CFO Mortimer has posted our Oct finances and we've scraped out yet another profit. Wait, who's laughing? Oh, that would be Wernher von Kerman with his huge 2021 R&D budget proposal, not to mention looming R&D costs for Mk3 development. But for now - green! docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
altho it was not damaged, the recovered booster will not fly again - but it will be static-fired once more late next month to confirm it possibly could be re-flown. We will iteratively increase this pattern with re-use of additional boosters moving forward until a failure occurs
Kerbal Space Agency
@KSA_MissionCtrl
post-launch ops complete & we are proud to say the Progeny Mk7-B ends service with a fully successful mission - finally! The SRB was recovered 16km downrange just over the horizon from KSC. Minor concern this mission was it possibly coming down over land & being damaged
Kerbal Space Agency
@KSA_MissionCtrl
already cheers in Launch Control after the 1st stage performed as expected. Recall this is the same booster flown on the 1st Mk7-B mission in August! A great accomplishment. Now hoping rest of mission goes as well. Staging should be occurring right about now...
Kerbal Space Agency
@KSA_MissionCtrl
booster ignition & LIFT OFF!! The MK7-B heads up on its final mission, rolling off the pad to orient 34° NE then starting pitch-over, which will not be phased just a continuous movement. BECO <1min followed by a coast to 25km for staging. GO PROGENY! 🚀
Kerbal Space Agency
@KSA_MissionCtrl
it's not time yet for everyone to enjoy the weekend - majority of Kerbin II operations team will be at it until late today - but if it's time for you to log off already be sure to first catch up on major events from these last two weeks: kerbalspace.agency/?p=11332
Kerbal Space Agency
@KSA_MissionCtrl
flight analysis for the (likely) final Ascension Mk2 mission is now available - kerbalspace.agency/?p=11337 with the success of the Viklun upper stage we can finally complete the design of the Mk3 & expect to have a blueprint by the end of the month
Kerbal Space Agency
@KSA_MissionCtrl
our CFO Mortimer is excited to be busy working with the Ascension team on laying out contract submission guidelines that will be published later this year to allow for companies to send us proposals for satellites to be launched on the Mk3 in 2021, currently focusing on LKO/HKO
Kerbal Space Agency
@KSA_MissionCtrl
it may be only 4 calendar years since we started the KSA but in that time Kerbin has orbited the sun 14 times as of today! There are also still 4 outer planets starting with Sarnus that have not even completed a single orbit around Kerbol yet (Sarnus' 1st orbit ends 11/2024)
Kerbal Space Agency
@KSA_MissionCtrl
Periapsis Co. has confirmed the refurbished Boostertron II from the 2nd Aug Mk7-B flight will be delivered to KSC on schedule this week. It is the fastest turnaround yet, they've been gradually reducing the time needed to recast the solid fuel over the course of this year
Kerbal Space Agency
@KSA_MissionCtrl
new delivery from the rail depot - the Mk1-B capsule has arrived for its qualification trials. It's not meant to carry a kerbal into space, yet. Over the next two months it will undergo atmospheric testing & recovery then get shot off into space in 2021 if all goes well
Kerbal Space Agency
@KSA_MissionCtrl
post-launch operations wrapping up, first stage was once again recovered successfully and is on its way back to the HAB where the fins, chutes and structural adapter will be removed so it can be shipped back to Periapsis Co. for refurbishment & hopefully reflight
Kerbal Space Agency
@KSA_MissionCtrl
booster ignition and we have LIFT OFF! This booster will be running for the third time but first time in flight to carry the Mk7-B close to or even into the upper atmosphere. If all goes well, the 2nd stage will be pushing the rest of the way before this first minute expires
Kerbal Space Agency
@KSA_MissionCtrl
ahhhh simpler times... #OTD 2016 we didn't have to worry about collateral damage if a rocket exploded - its effect would barely clear the launch site. Now we have a complete fire response service on call at KSC which we've thankfully only had to use once twitter.com/KSA_MissionCtr…

bank account remains stable as CFO Mortimer releases our Sept financial report. We're looking good for the remainder of the year. Thanks to all our bit.ly/KSA_Patreon supporters helping to keep us afloat! docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
the Mobile Launch Platform has been rolled back to the VAB and the support legs and engine mount for the Progeny Mk7-B have been installed. Some regular maintenance has been performed on the Ground Service Equipment and all looks good for rollout & launch next week
Kerbal Space Agency
@KSA_MissionCtrl
there was no decay detected in the orbit of the Ascension Mk2's upper Viklun stage, however this could be due to its short stay in space and the fact that our own measurements may still be largely inaccurate. It's now up to Kerbin II's longer mission to possibly determine
Kerbal Space Agency
@KSA_MissionCtrl
just firing the booster again doesn't also account for loads & stress during flight. If 3rd Mk7-B flight is good, we will delay the 4th flight in order to re-use the booster from the 2nd flight and see if a pre-flown, not just pre-fired, booster can also remain functional
Kerbal Space Agency
@KSA_MissionCtrl
huge milestone today as the booster recovered from the ocean after last month's 1st Progeny Mk7-B flight was successfully static fired on our horizontal test stand. This upcoming 3rd Mk7-B flight will use a booster that was originally fired in Mar and again in Apr
Kerbal Space Agency
@KSA_MissionCtrl
Kerbin II has by now exceeded both Kerbin I's record mission distance of 396,096.3495km and the Ascension Mk2's orbit total of 37 and of course it still has a long ways yet to go so bit.ly/KSARecords has updated to refer to Kerbin II with a "+" to note ongoing progress
Kerbal Space Agency
@KSA_MissionCtrl
two new bit.ly/KSARecords have been confirmed from the latest Ascension Mk2 mission (old/new):
• Heaviest Payload Launched
(Orbital Trajectory): 0.661t/0.767t
• Most Stable Orbits
(Around Kerbin): 20/37
Congrats to the Ascension team!

Kerbal Space Agency
@KSA_MissionCtrl
rocket was off nominal pitch at staging because it had gone high enough that the fins couldn't hold attitude anymore. This was a minor oversight from dampening controls - future flights can widen the movement limits as the rocket climbs so the fins can remain effective even >40km
Kerbal Space Agency
@KSA_MissionCtrl
so nice to see our improvements to the Viklun stage were effective, as well as retro thrusters on the lifter decoupler. Here is staging & PLF separation. Future improvements will still be needed, Mk3 will now get larger tanks for RCS fuel since these thrusters are so thirsty
Kerbal Space Agency
@KSA_MissionCtrl
as we analyze data internally, you can also look at some of what we're working with as telemetry from the Mk2 mission has been made available. Includes only launch/ascent/OIB & de-orbit burn/descent. Loss of tlm at atmosphere was due to a runtime error docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
a visual overview of the Ascension Mk2's mission, during which it traveled 196,993.249km from launch to hitting the top of the atmosphere, orbiting Kerbin a little over 37 times. Data processing underway to determine if its orbit decayed at all during that time
Kerbal Space Agency
@KSA_MissionCtrl
#ICYMI earlier today we de-orbited the Viklun stage and nabbed a first mission success for the Ascension Mk2. Did anyone else watch its demise in the Ops Tracker? If not then here you go - without LKO probes it's easy to forget this view updates every second!
Kerbal Space Agency
@KSA_MissionCtrl
we lost data on atmospheric interface so the flight computer likely crashed for some reason. Unfortunate, but nothing really lost - we mainly wanted to confirm entry point and have that information. Stage likely disintegrated prior to splashing down. Complete mission success!
Kerbal Space Agency
@KSA_MissionCtrl
we had good engine start and nominal burn! Just enough battery power remains to allow telemetry data to continue transmitting to us until plasma blackout occurs. Here is the full command log from when the stage came out of hibernation earlier
Kerbal Space Agency
@KSA_MissionCtrl
~3min of slow movement has flipped the Viklun stage over to face retrograde. RCS fuel remains at a premium so careful manual control used to ensure enough remains thru burn as retrograde orientation is a slow-moving target that needs constant adjustment. M-3min
Kerbal Space Agency
@KSA_MissionCtrl
we've picked the Viklun stage back up after comm blackout as it passes over Arekibo. The pings sent to ground stations along the way to its de-orbit burn will allow us to constrain its orbit to determine if any decay took place. Burn instructions have been uploaded & accepted
Kerbal Space Agency
@KSA_MissionCtrl
the Viklun stage has begun its final orbit, it will be waking up soon as it passes over DSN Central so we can begin prep for deorbit burn. Plan is to splash it down off the coast east of Ockr within the next hour, which is our regular ocean graveyard. Plot ends at atmosphere
Kerbal Space Agency
@KSA_MissionCtrl
with the main engine putting out the amount of power it was supposed to this time, SRB drop occurred as planned and fell away from the rocket on separation. Altitude & downrange distance were also sufficient this time that none of the boosters fell back anywhere near the runways
Kerbal Space Agency
@KSA_MissionCtrl
off-duty watch was carried out with no issues, Kerbin II continues to function nominally and we had a good health check with the Viklun stage, now back in hibernation until later today. Controllers will continue to work on getting Kerbin II ready for science observations next wk
Kerbal Space Agency
@KSA_MissionCtrl
The Viklun stage, which is now operating on a single flight computer (can swap to backup if needed), has been hibernated with enough batt power to last over a day. It will be deorbited tomorrow. Kerbin II checkouts are still underway but so far no issues have been raised
Kerbal Space Agency
@KSA_MissionCtrl
more cheers & applause in Mission Control as we receive data from Kerbin II, now floating free! 1 step closer to mission success for the Mk2! If you're looking at the Ops Tracker, Mk2 now has a link to Kerbin II but if not head here for spacecraft deets: ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
final checks on Kerbin II are looking good, just 1-2min now from deployment. Stand by! Viklun has switched to battery power to prep for loss of RTG. Locks on the payload truss will open to allow springs to gently push Kerbin II away. It should then power up & check in after 10s
Kerbal Space Agency
@KSA_MissionCtrl
translation complete, final activation sequence for Kerbin II is underway to prepare its flight computer for post-deployment boot up. We will then test the RCS thrusters, connect the batteries, open the cold gas fuel valves and activate the cold gas engine
Kerbal Space Agency
@KSA_MissionCtrl
controllers prepping to orient the Viklun stage radial-out for deployment. With high-pressure RCS fuel low, just a blip is used to get the spacecraft slooowwwlly moving in the right direction, then SAS will be switched back on to lock orientation with reaction wheels
Kerbal Space Agency
@KSA_MissionCtrl
prep for Kerbin II deployment continues with both primary & backup radio antennas now extended. We'll need some time to test & ensure comms to Kerbin II are working properly but are looking to kick the spacecraft free within the next hour
Kerbal Space Agency
@KSA_MissionCtrl
Viklun stage has just completed its first full orbit. Coming around from the night side back into sunlight earlier the team deployed the RTG's extendable arm so the heat it radiates does not fall so heavily back on the spacecraft, which is also in a slow roll for thermal control
Kerbal Space Agency
@KSA_MissionCtrl
as post-launch ops begin on the ground, orbital ops are now underway in space! Controllers are getting the Viklun stage flight computer launch ops purged & set up for orbital ops. Then we will begin prep for Kerbin II deployment later today. Ops Tracker will continue to update
Kerbal Space Agency
@KSA_MissionCtrl
KERZZAH!! orbital insertion success for the Mk2! 💫 \[0_o]/ our reaction may seem delayed but data from spacecraft had to be checked & confirmed. Launch Control is in an uproar as everyone congratulates each other. FD Lanalyle officially announces LC is now MC - Mission Control!
Kerbal Space Agency
@KSA_MissionCtrl
coming up on orbital insertion burn. Everyone on the edge of their seats. Nothing finesse about this - just point prograde, crack the throttle wide open and trust in thrust. Resulting orbit will not be perfectly circular but we're not aiming for such things yet. Let's GOOOOOO
Kerbal Space Agency
@KSA_MissionCtrl
the faster computers down here crunched the numbers and we sent up the resulting burn timings to the Mk2. SES-2 will occur @ 19:52:10 UTC and last for 54s. Tank pressure is good for restart, RCS fuel levels are a bit low but Kerbin II reaction wheels are enough to hold prograde
Kerbal Space Agency
@KSA_MissionCtrl
a bit scary at staging seeing the pitch constraint go into the red but Viklun was able to recover, held proper attitude and we have achieved target apokee! Ascent was actually more efficient than planned, leaving us with extra fuel in the tank. OIB planning underway
Kerbal Space Agency
@KSA_MissionCtrl
still looking at a nominal ascent, first major milestone reached w/Ap in space to secure us time to react if Viklun fails to hold attitude after stage sep, which is the next major event coming up now as we are just seconds from MECO. Everyone hold on to your butts...
Kerbal Space Agency
@KSA_MissionCtrl
rocket remains on pitch profile, TWR hold @ 1.5 was good this time so velocity is nominal. Roll ctrl on pitch fins was disabled earlier so flutter is reduced as it passes now through transonic regime. Engine chamber pressures nominal. SRBs falling downrange just offshore
Kerbal Space Agency
@KSA_MissionCtrl
good main engine start, SRB ignition & we have LIFT OFF!! Kerbin II is on its way to space atop the Ascension Mk2, rolling from 45° onto 60° then pitching downrange. Boosters putting out 274kN pushing the rocket almost by themselves, will burn out to be dropped after 33s
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] assuming at T-30s "Go Ascension!" & "Go Kerbin II!" streaming telemetry should load in the Ops Tracker - tune in now - ops.kerbalspace.agency We again hope to provide real-time data through OIB. If abort, you will see that too. But hopefully not! Final launch sequence:
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] terminal countdown has begun with the AFCS taking control of the launch sequence. Service booms have swung away, gangway retracted. Rocket is on internal power and RF comms. SRB hold-down bolt explosives armed. Viklun's dual flight computers are synchronizing
Kerbal Space Agency
@KSA_MissionCtrl
we are keeping the same constraints as first launch. Plenty of room for error on ascent but if any values start to get too far off nominal you will see highlight flashes on the telemetry stream according to these values being exceeded
Kerbal Space Agency
@KSA_MissionCtrl
[L-4m] preliminary pressurization of the Viklun tank underway. Lower tank is supported by SRBs on launch stand but upper tanks need extra support once service boom swings away to keep rocket secure against any strong wind gusts prior to lift off
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] final readiness polls - Tracking: GO! Flight: GO! Range: GO! Weather: GO! Payload: GO! Launch clearance granted from Ops Dir @DKerman_KSA! FTS is on internal power, service towers unlocked for retraction. The air in Launch Control feels electrified
Kerbal Space Agency
@KSA_MissionCtrl
[L-13m] onload of nitrogen gas has begun for the Viklun stage, which will be used for fuel tank pressurization for engine restart and RCS. The high-pressure vessels are filled late to prevent any rupture from harming pad crew
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] RSO has closed the range, rocket engines are ARMED, Flight Termination System is ACTIVE. All visitors must remain in designated areas and hearing protection while outdoors is REQUIRED. Any incursions will immediately hold the count
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] update from the weather desk on surface conditions remain 90% GO with an eye on wind gusts off the grasslands due to a low-pressure system offshore. Data still being received & analyzed from upper-atmo but we are cleared into the final countdown launch phase
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h] now into the final hour of the count, MLP is secured & controllers are performing ascent simulation to ensure all consoles and rocket are properly configured for the mission. Visitor areas are filling up fast - tickets sold out to this launch in record time last week
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h35m] high-altitude weather ballon has begun its ascent to give us an update on upper-level conditions in time for the final general polling at L-5min. MSV Aldeny has reported in, downrange in the Kerblantic in case of emergency recovery operations due to inflight abort
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h45m] issues board remains clear, rocket is ready to go! Pad crew securing the launch equipment while Range Safety Officer performs another check of airspace & waters around KSC in and under ascent corridor/stage splashdown areas
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h30m] no issues raised so far, preflight continues on sched as pad workers clear out to allow controllers to run checks on the 6 engines that will be powering the rocket up into space, including the hardware currently holding them down
Kerbal Space Agency
@KSA_MissionCtrl
this is not where you wanna be come launch, but even still looking up at the Ascension Mk2 can be an intimidating sight. If you could withstand the heat, the acoustic vibrations would practically shake you apart. Taken by a pad worker lying on their back
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h15m] controllers are on console, rocket being woken up to load flight software while pad crew begins to remove launch safety hardware and run GSE prechecks. The code powering this mission is fully available on our github - github.com/KSAMissionCtrl…
Kerbal Space Agency
@KSA_MissionCtrl
the rocket will be following an optimized ascent profile so you will see Ascent Phase callouts in the flight log as it transitions between pitch profiles. We hope to follow more accurately than our first attempt, breaking down the ascent into 9 phases instead of 2 this time
Kerbal Space Agency
@KSA_MissionCtrl
2nd contingency is for total ascent failure. Because Kerbin II is designed to be recoverable at mission end that means it can also abort inflight and save itself. If it splashes down we could still lose it, but such an abort would likely be late-ascent over land
Kerbal Space Agency
@KSA_MissionCtrl
one of 2 mission contingencies is if Viklun attitude control still incapable. Engine will cut this time, apokee should already be >70km by time of SES-1 if main throttle properly holds TWR in early ascent this time. Should be able before Ap to insert with Pe just outside atmo
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h50m] Flight Director Lanalye has her A team ready for final preflight briefing. Mission profile will be similar to that of Kerbin I, looking to insert into an inclined circular orbit. Original inclination was higher, but reduced to increase ascent error margins
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h30m] Wx balloon released earlier has given us a favorable 90% GO forecast for today's launch attempt. Teams are assembling around KSC to begin prelaunch operations. Rocket remains tanked, so condensed countdown will be as follows. Expect updates at these milestones

the RTG was successfully installed today, Kerbin II was powered up and confirmed to be in good shape. It will now remain switched off until it is deployed - hopefully in orbit! All launch readiness reports are GO and prelaunch ops will kickoff tomorrow @ 15:16 UTC if Wx holds
Kerbal Space Agency
@KSA_MissionCtrl
we'd like to note that this is technically Ascension's 4th attempt at orbit. 2 attempts by the Mk1 & 1st Mk2 attempt failed cause Kerbin I had to insert itself into orbit. This time we are looking for the Mk2's upper Viklun stage to do the job of inserting the payload into orbit
Kerbal Space Agency
@KSA_MissionCtrl
ground service equipment came up with no issues, rocket was tanked & wet dress rehearsal went well earlier today. Tomorrow we will again attempt to install the RTG so Kerbin II can be powered up & undergo final pre-launch testing. Meanwhile, the Ascension Mk2 sits looking pretty
Kerbal Space Agency
@KSA_MissionCtrl
the Ascension Mk2 is back on the pad atop the MLP, being hooked up to the service towers, transport struts removed & engine support stand installed. It will undergo another full wet dress rehearsal because there's no good reason to assume everything is still fine from last week

@KSA_MissionCtrl
modifications have been made that should allow us to properly install the RTG on Kerbin II after roll out - we will try again next week. All other supporting requirements for launch attempt remain ready. Another relaxing weekend for mission controllers, do enjoy!
Kerbal Space Agency
@KSA_MissionCtrl
our Tracking Station dishes do not have much of anything to track in space right now but they still go through the motions as controllers run exercises that simulate on-orbit operations. They are now well-practiced and ready for when we have numerous satellites up there
Kerbal Space Agency
@KSA_MissionCtrl
the Ascension Mk2 launch delay will not have a knock-on effect for the Progeny Mk7-B launches yet, still time between delayed launch and 3rd Mk7-B launch to reconfigure pad as needed. Further delays however would also start to push back Mk7-B missions
Kerbal Space Agency
@KSA_MissionCtrl
our seemingly well-laid plans for installing the RTG on the pad have come up against some unforeseen and insurmountable problems - at least, this time. We are forced to roll back to the VAB and make some adjustments. Launch delayed until next week ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
technicians will access the rocket via the crew gangway to install the RTG today via a hatch in the fairing. Hooked up to the tower environmental system used for capsules the RTG heat will be pumped away and Kerbin II can be powered up and tested
Kerbal Space Agency
@KSA_MissionCtrl
the Mk2 was rolled out at the start of today to be hooked up to the service towers and undergo a wet dress rehearsal that saw it loaded up with 9t of liquid propellants between its 2 stages. All systems were good & we remain on sched. RTG installation will take place tomorrow

@KSA_MissionCtrl
final checkouts on the Ascension Mk2 have been completed, the rocket stands ready atop the Mobile Launch Platform, set to roll out from the VAB and head to the pad on Monday ahead of launch attempt on Wed. Ready, set... GO? That's what we're hoping for!
Kerbal Space Agency
@KSA_MissionCtrl
we all have our heads down working hard towards next week's mission, which don't forget will not just be a few mins long! If all goes well we will have a lot of ongoing mission updates to bring you afterwards and we are excited to share more on-orbit ops after Kerbin I's success
Kerbal Space Agency
@KSA_MissionCtrl
get the details on Bob's harrowing journey up into space with the flight analysis report just published today: kerbalspace.agency/?p=11253 the rocket survived a punishing ascent and we came the closest we've been so far to losing a crew member in flight
Kerbal Space Agency
@KSA_MissionCtrl
vehicle stacking is progressing well in the VAB. The RTG has just recently arrived, although it will not be installed until the day prior to launch. Tracking dishes here and other ground stations are being calibrated. We remain on sched for launch next wk! ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
background details: the train is heading out to Umbarg from the rail depot and Minmus is framed within our vertical test stand
Kerbal Space Agency
@KSA_MissionCtrl
the Boostertron II originally static fired back at the start of April has just been fired again earlier today on our horizontal test stand. Data still needs a full review but initial results were good. If confirmed we would be clear to fly a refurbished one w/3rd Mk7-B in Oct
Kerbal Space Agency
@KSA_MissionCtrl
word from KW Rocketry is the test data from the WildCat-V static fires here on our vertical test stand show that the engine is ready for production and we will be receiving our first ones on schedule by the end of this year to power the Ascension Mk3 into space by Q2 2021!
Kerbal Space Agency
@KSA_MissionCtrl
the Mobile Launch Platform was rolled out to the pad today to perform checks on it and the ground service equipment. No issues were found, launch schedule remains on track. It's now back in the VAB and already has the lifter section stacked on it
Kerbal Space Agency
@KSA_MissionCtrl
CFO Mortimer has updated our financial statements to include August. As always, many thanks to our bit.ly/KSA_Patreon supporters for helping us still manage to turn a small profit this month. Full report: docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
the separate sections of the Ascension Mk2 - lifter, orbital, payload - are all finishing up their individual checks prior to the start of vertical stacking later this wk on the Mobile Launch Platform parked to the rear, which also needs attention as it's not been used since Feb
Kerbal Space Agency
@KSA_MissionCtrl
there could be three pads with a smaller one added for Progeny. It all depends on how much trouble it would be to use the current pad GSE for both Progeny & smaller Ascension or even if any smaller Ascension would still be flying to compete with pad use
Kerbal Space Agency
@KSA_MissionCtrl
this has raised the question about multiple launch pads at KSC. At this time we do not have any plans set, but eventually there will at least need to be one additional larger pad built further away when Ascension rockets reach 2.5m
Kerbal Space Agency
@KSA_MissionCtrl
Luciole & Progenitor have continued to iterate on designs, including a single-stick and "heavy" configuration for the Progeny Mk8. There has also been talk of a custom-made launch base that would carry the vehicle out to the pad, although this would require use of the VAB
Kerbal Space Agency
@KSA_MissionCtrl
from the beach south of KSC, yesterday's Progeny MK7-B arcs towards space, marked by the smoke trail of its lower stage SRB, sailing past Mun and Minmus. Now imagine 4 of these engines and that's what an Ascension Mk3 launch will look like next year!
Kerbal Space Agency
@KSA_MissionCtrl
it's time to get hype for our 2nd orbital mission launching next month!! Vehicle construction is going well, mission planning is in its final stages. More details will be shared over the coming weeks but for mission/vehicle overview see the Ops Tracker: ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
the final K2-X engine ordered in Feb (and final engine overall of this make) has been delivered. This will tide us over into early 2021 while the first production delivery of the WildCat-V later this year paves the way for future lifter engines through the remainder of next year
Kerbal Space Agency
@KSA_MissionCtrl
#OTD in 2018 we published the 1st report on the high-radiation region over the planet that was discovered the previous yr by a Progeny Mk5 rocket. We've poked at it several times since, but a dedicated orbital mission launched by Ascension is still needed twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
today is the first time KSC visitors can get an up-close look at the Ascension Mk1-A capsule that carried Bill & Val into space and saved Jeb with a pad abort. This is the first *actual* piece of flight hardware to be featured in our rocket garden
Kerbal Space Agency
@KSA_MissionCtrl
here's how we're hoping the Ascension Mk3 will look, with a standard 3.5m fairing and Mk1-B capsule. Just waiting on confirmation the Viklun stage improvements work (in Sept), the new lifter engine is good and the SRBs are flight capable (latter two are looking good already)
Kerbal Space Agency
@KSA_MissionCtrl
we acknowledge this is quite the attempt for what would also likely be our 1st interplanetary mission, but the chance for getting a probe to the outer Kerbol system for only ~2km/s Δv is just too good to pass up & we will do our best to make it work with whatever we have by then
Kerbal Space Agency
@KSA_MissionCtrl
one year until the launch window for Extremis 1 opens, which is being planned to fly by Eve, Jool and Plock over the course of just longer than 2 years. This would most likely be launched on an Ascension Mk3, altho not ruling out the chance of a slightly more capable Mk4
Kerbal Space Agency
@KSA_MissionCtrl
Progenitor have moved into the Horizontal Assembly Building, which can still vertical load test their rockets while Ascension will now have more room in the VAB for future rockets wider than 1.25m. The next Mk7-B has begun its final adjustments & checks for launch next week
Kerbal Space Agency
@KSA_MissionCtrl
great news from Periapsis Co. confirming that the data from last static fire of the refurbished Boostertron II shows a nominal performance. Now, we just need to repeat the performance and the booster after that will see a reflight instead of a retest!
Kerbal Space Agency
@KSA_MissionCtrl
the RTG for Kerbin II has been assembled on sched despite mission delay, meaning it will be putting out less power by the time the mission launches due to the continual decay of the Kuudite but the difference will not matter for this mission, launching no earlier than mid-Sept
Kerbal Space Agency
@KSA_MissionCtrl
Specialist Bob has submitted to rigorous medical testing this past week as physicians work to determine why he was the only one who blacked out on re-entry when centrifuge exercises showed he should have been able to handle the G load that was similar to Val & Jeb's returns
Kerbal Space Agency
@KSA_MissionCtrl
it took the software team a while to work with the engineers and replicate the LES decouple anomaly but finally we can publish the full flight report for the 11th space radiation study launched back in June. What do all these plots mean? Find out: kerbalspace.agency/?p=11126
Kerbal Space Agency
@KSA_MissionCtrl
big spending this month is what we want to see, working hard to get Ascension closer to being able to accept full commercial launch contracts. CFO Mortimer says we are still looking healthy to continue operations as planned thru 2020. Full report: docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
get caught up on KSA operations to ensure you don't miss what's currently going on at the KSC campus: kerbalspace.agency/?p=11128 plus even a bit more we couldn't squeeze in to the news card. Everyone have a great weekend!
Kerbal Space Agency
@KSA_MissionCtrl
the answer to our earlier photo about the missing part on Kerbin II is the RTG produces enough heat to become an issue when encapsulated within a fairing - so it will not be installed onto the satellite until just before launch through a special access hatch
Kerbal Space Agency
@KSA_MissionCtrl
the third & final static fire test of the WildCat-V engine has been completed - still no explosions! Test articles & data will be sent back to KW Rocketry for final analysis. No problems means we get flight-ready hardware at the start of 2021 to launch the Ascension Mk3!
Kerbal Space Agency
@KSA_MissionCtrl
.@starseeker8749 correct on the part, but wrong on the reason. The RTG is safe to handle - alpha particle decay doesn't even penetrate skin so easily contained within the unit itself. Security is a general concern, not just here at KSC during final integration
Kerbal Space Agency
@KSA_MissionCtrl
we have received Kerbin II from OKTOsat to prepare it for fairing encapsulation and mounting on the launch vehicle under assembly behind the photographer. Can anyone spot the missing element of the satellite and tell us why it's not there?
Kerbal Space Agency
@KSA_MissionCtrl
the new capsule that will fly on the Ascension Mk3 has been finalized! The test article will arrive later this year to begin qualification and we hope it will carry a kerbal up into orbit by mid-late 2021. And beyond? No, just meant for LKO with only 1 day of life support
Kerbal Space Agency
@KSA_MissionCtrl
high-altitude KerBalloon crew should have reached their target location yesterday and should have released their balloon today. If so, we expect them back at the Kongo base late tomorrow. Soon we will have CommSats to enable us to stay in touch better with ground expeditions!
Kerbal Space Agency
@KSA_MissionCtrl
all 4 crew's sub-orbital re-entry profiles. Bill was 1st so most conservative. Val then Jeb were next, Bob's mission went the highest. Bob was the only one who blacked out - the final flight report will attempt to determine the cause. Bumps after max G are chute deployments
Kerbal Space Agency
@KSA_MissionCtrl
the Boostertron II 1st test fired in early Mar was refurbished & has been fired for a 2nd time. Good news is no immediate issues were detected during this static fire, however full data analysis still needs to be completed to determine performance was 100%
Kerbal Space Agency
@KSA_MissionCtrl
back at KSC now, Bob enjoyed his time off and hero's parade through his home cavern of Kravass along with a phone call from the Presider. He's amped up to get working with the rest of the crew to prepare for a longer stay in space next year - orbit! (either him or Val to be 1st)
Kerbal Space Agency
@KSA_MissionCtrl
our next orbital payload has been completed and will be shipped to KSC by the end of this month to be integrated w/ its Ascension Mk2 launch vehicle. Kerbin II will test a functional RTG, comms tech & perform science and kerrestrial observations. Full res: flickr.com/gp/kerbal_spac…

@KSA_MissionCtrl
Luciole will settle the current lawsuit against USI that was preventing us from launching Progeny rockets. The Mk7-B will fly in August - dates coming next week. This does mean tho the next Ascension Mk2 mission will be pushed back to early/mid Sept. Then more Mk7-B NET Oct
Kerbal Space Agency
@KSA_MissionCtrl
we've met w/@LucioleSpace CEO Wellbur Kerman & formalized our partnership. They are absorbing USI, which means we will still have access to Progeny Mk6 parts, including the single-segment SRBs should the Boosterton II's fail to be certified by the time Ascension Mk3 is rdy to fly
Kerbal Space Agency
@KSA_MissionCtrl
Launch Vehicle Designer (bit.ly/KSP_TOT) continues to grow more complex but so will our missions, thus it will continue to allow us to communicate various aspects of them visually. While this is a demo by the developer, the Ascension Mk3 could do a Mun flyby like this
Kerbal Space Agency
@KSA_MissionCtrl
Hot! Hot! Hot! 🔥 the 2nd WildCat-V test engine also survived a full-length static fire on the test stand today. Like the first test it was put through various throttle ranges. Lead Engineer Simon reports he is pleased - so far performance is as expected!
Kerbal Space Agency
@KSA_MissionCtrl
to get an idea of just how much panic was caused by Bob's initial ascent (red) compare it to the trajectory he was supposed to fly (green). Had the rocket not recovered and shown to hold good AoA and keep nose at or above 45°, abort would have been triggered by controllers
Kerbal Space Agency
@KSA_MissionCtrl
how did we recover the capsule with an airship? We tested a similar method over water #OTD back in 2018 and since then have perfected the procedure and kept it in our back pocket for use when needed over land or sea twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
one more photo from Bob's mission, one of the last few he took prior to returning to his seat for re-entry. Looking northeast, you can spot the aurora & also see the island he landed on just over the terminator. To the left far below is the mountain upon which sits Ockr Relay
Kerbal Space Agency
@KSA_MissionCtrl
we've now sent all 4 of our crew up into space. To think that just over 3 years ago they were all only dreaming of the possibility. The Progeny Mk3 rocket seen launching in this photo still hadn't even made it to the upper atmosphere yet!
Kerbal Space Agency
@KSA_MissionCtrl
Bob has been given a clean bill of health, which is great news considering he blacked out for 24 seconds during the most punishing point of re-entry, which saw over 9G for nearly 10s, 4s of which was over 11G and nearly 12G. He's now heading back home to Kravass for some R&R
Kerbal Space Agency
@KSA_MissionCtrl
although it did not travel as high as planned, Bob's flight still managed to pull ahead of all Val's sub-orbital 2019 bit.ly/KSARecords & also set a new record for longest downrange distance from which a sub-orbital vessel was successfully recovered ops.kerbalspace.agency/?body=Kerbin-S…
Kerbal Space Agency
@KSA_MissionCtrl
MSV Aldeny has pulled into port at Sheltered Rock and Bob will be given a full medical exam tomorrow. Capsule is still there as well and will be shipped the rest of the way back to KSC for post-flight inspection next week. This was its second flight
Kerbal Space Agency
@KSA_MissionCtrl
we hope everyone else had as good a week as we did! Although yesterday's mission concludes kerbed space flight for 2020, we have details on upcoming Ascension missions in our weekly Ops Summary: kerbalspace.agency/?p=11107
Kerbal Space Agency
@KSA_MissionCtrl
we had two opportunities during the Kerbin I mission to also capture Mun's shadow but it wasn't in the proper planned orbit right after launch that would have given it visibility and then also just missed it during a perikee pass a few days later on 2/23 thx to missed maneuver
Kerbal Space Agency
@KSA_MissionCtrl
here's the first time we've ever seen Mun's shadow from space! First photo taken ~140km & second at apokee over Sheltered Rock @ 294km. Note the land seen to the right of img1 extends into the shadow & contains KSC but it gets too dark to see it
Kerbal Space Agency
@KSA_MissionCtrl
with the capsule recovered we now have the rest of the onboard telemetry. The full data set is available online for anyone to peruse and analyze as they wish: docs.google.com/spreadsheets/d… and here is the remaining operations log
Kerbal Space Agency
@KSA_MissionCtrl
Bob is only a little more than halfway through the sea journey back to Sheltered Rock but airship recovery of the capsule is already completed. Here is a photo he took of the landing site. Space photos will need add'l processing but we hope to release them today too
Kerbal Space Agency
@KSA_MissionCtrl
it was a ~22km hike from his capsule to the shore but Bob made it okay - all that wilderness survival training finally coming in handy. Aldeny crew was there to greet him, he's now heading aboard to sail back to Sheltered Rock. They will arrive in port tomorrow
Kerbal Space Agency
@KSA_MissionCtrl
the Civvie has been relieved by another pilot with her personal craft & it remains circling offshore to relay comms over the horizon. The Aldeny has arrived and made contact with Bob, who has been working towards the shore, performing various surface observations along the way
Kerbal Space Agency
@KSA_MissionCtrl
✨🎉 KERZZAH!! 🎊✨ \[0_o]/ the Civvie has returned w/in range of Ockr relay to report Bob is indeed safely down, no injuries from landing in grassland area. MSV Aldeny is still about 2-3 hours away. Capsule is reportedly well inland, so it will need to be recovered separately
Kerbal Space Agency
@KSA_MissionCtrl
post-launch operations continuing as flight data is pulled from launch consoles and organized so the Ascension team can begin to look into the guidance issue that plagued the start of the mission. Could be mechanical, could be software. They will hunt it down w/ vengeance
Kerbal Space Agency
@KSA_MissionCtrl
a Civvie volunteer has just departed from Ockr General to serve as relay messenger between us and the Aldeny as it sails over the horizon. It will also get to the island sooner to confirm Bob's status and location. Should be there & back w/in 2 hours. thx to public for support!
Kerbal Space Agency
@KSA_MissionCtrl
Bob should have landed by now. If uninjured he can egress from the capsule on his own. He has 4 days of food and water in addition to the capsule for shelter, but there's no reason why we shouldn't find him later today as search & recovery operations kick off full force
Kerbal Space Agency
@KSA_MissionCtrl
capsule should now be descending slowly under ALL chutes - controllers recommended to Bob he pop the reserve radials as well even if the mains open to help make the landing softer since he will not be splashing down into the ocean. Heat shield will also be sacrificed to help
Kerbal Space Agency
@KSA_MissionCtrl
we had Bob calling out readings non-stop to make clear when comms dropped out. Now just static. The Aldeny is still several hours from the island but telemetry data prior to signal loss has everyone fairly confident that is indeed where he is coming down
Kerbal Space Agency
@KSA_MissionCtrl
Bob is strapped into his seat again for a rough ride back to Kerbin. Capsule is retrograde & LES jettison will occur shortly before re-entry in <1min. Capsule spun up to keep radial chutes cool. We don't expect to regain comms after plasma blackout. Good luck, Bob!
Kerbal Space Agency
@KSA_MissionCtrl
decision made to hold off on LES use. It's looking like Bob will come down right smack dab in the middle of this large island, which would be preferred over having him floating for hours in an open sea that could be rough. Val is telling Bob to begin re-entry prep
Kerbal Space Agency
@KSA_MissionCtrl
approaching apokee & discussion is still underway whether to use the LES to put the brakes on and bring the capsule down sooner, altho the steeper re-entry will put more Gs onto Bob, who is now floating around and saying he's getting a great view of Mun's shadow far down below
Kerbal Space Agency
@KSA_MissionCtrl
Bill has already shucked his suit to be in Launch Control with everyone else to see how this plays out. Apokee in ~4min & Bob's flatter trajectory will take him well downrange. MSV Aldeny is already starting to move eastwards at best speed
Kerbal Space Agency
@KSA_MissionCtrl
controllers are scrambling to plot Bob's new trajectory as he takes over control to begin orienting the capsule to get some good views out the window. Despite the guidance issue, we are still pleased at how well the rocket carried out the rest of the ascent
Kerbal Space Agency
@KSA_MissionCtrl
bumpy ride is smoothing out, close eye kept on external temp as friction heats up. Throttle pull back to maintain 2.7 TWR ended at 40km to jam Bob back in his seat with 4G+. We will at least make it up to space - primary goal achieved!
Kerbal Space Agency
@KSA_MissionCtrl
WHOA. Okay, guidance issue. Rocket thinks its nominal tho so not auto LES. Tlm shows it *is* still under control w/o danger of flipping. Controllers have left abort decision up to Bob. Shaky response but nonetheless he says "push on push on!"
Kerbal Space Agency
@KSA_MissionCtrl
ignition & launch thrust good - we have LIFTOFF! Spc Bob is finally on his way to space for the 1st time, outrunning the shadow of Mun as it passes over the KSC. Once clear of the towers, engine will kick up from ~70% to full thrust
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] it's time to load the Ops Tracker if it's not already to watch live ascent tlm, which should load up after T-30s if final primary polls come back GO. The final automated sequence follows. Val excitedly tells Bob to "hold on tight & enjoy the ride!" ops.kerbalspace.agency

Val uses a rare lull in final procedures to ask Bob how he's doing. There is a tense moment of silence. Then, "I don't know why I thought you could see me give a thumbs up". Crew-facing cameras in the Mk1-B capsule? We could do that...
Kerbal Space Agency
@KSA_MissionCtrl
[L-13m] a small tanker still hooked to the service tower is loading nitrogen aboard the rocket, which will in turn be used to pressurize the fuel tanks for flight, mainly for extra rigidity as engine burns non-stop. Late onload ensures safety of pad crew. Bob has LES

storm threat has abated, with the Kerbin Weather Service reporting lack of organized development after a Deuce flight from Sheltered Rock investigated the area. There are still local weather conditions to be concerned about but these we are more familiar with by now
Kerbal Space Agency
@KSA_MissionCtrl
Flight Director Lanalye reports wet dress rehearsal went well and the rocket has been rolled back to the VAB. While it could most likely withstand the possible high winds & rain while mounted, we see no reason to put it through such a test, especially with a crewed mission
Kerbal Space Agency
@KSA_MissionCtrl
we have the possibility of bad weather later this week, Maritime Service is reporting conditions are ripe for a large low-pressure system developing out over the Kerblantic. Moving up Ascension Mk1 WDR to today, rocket is on the way out to the launch pad
Kerbal Space Agency
@KSA_MissionCtrl
Specialists Bob & Bill have both been settled into quarantine in the Astronaut Complex, where they will be monitored by medical teams while relaxing after their vigorous training. Not just to prevent sickness, also to get a good baseline medical reading prior to spaceflight
Kerbal Space Agency
@KSA_MissionCtrl
the Ops Summary is back and we will try to stick to the weekly format again moving forward. Learn more details about what went down these past two weeks and catch anything you may have missed: kerbalspace.agency/?p=11093
Kerbal Space Agency
@KSA_MissionCtrl
Bob's Ascension Mk1 was closed out today and loaded up on the carry vehicle. The crew also finished their last run of sim training. There were a few sim deaths, but FD Lanalye had to come up with some seriously out-there failure scenarios to kill either of them
Kerbal Space Agency
@KSA_MissionCtrl
while Bob's mission was able to be scheduled initially to coincide with the eclipse, that is not the primary mission goal and if there are any launch delays Bob has made it clear he will not be spending an extra 3 days in quarantine until the next eclipse
Kerbal Space Agency
@KSA_MissionCtrl
today kicked off with a kerbolar eclipse, and Mun's shadow raced across the KSC like as seen in this photo from 2017. Another eclipse will happen on 7/16 and the shadow of Mun will cross the Kerblantic underneath Bob's capsule as he views it from above for the first time ever!
Kerbal Space Agency
@KSA_MissionCtrl
the Mk1-A capsule was stacked atop the lifter stage earlier today in the VAB so the rocket can undergo load checks & ensure the decoupler/interstage shroud are properly manufactured. Then the rocket will be lowered horizontal for final close outs to complete by Friday
Kerbal Space Agency
@KSA_MissionCtrl
Kerbin II's mission will not last more than several weeks and in addition to the goals for the commsat qualification will carry out science observations regular commsats will not, such as radiation monitoring, kerbolar wind detection and Kerbin observation (cam opp rad instrument)
Kerbal Space Agency
@KSA_MissionCtrl
Kerbin II is undergoing final integration at our OKTOsat partner facility in Kravass for launch on the next Ascension Mk2 in late August. Going from 0.625m to 0.75m for the fuel tank is a tight squeeze for a 1.25m fairing but designers made it work for longer commsat life
Kerbal Space Agency
@KSA_MissionCtrl
by this month we had hoped to be static-firing recovered Boostertrons and possibly even re-flying one of them on the last of the 4 Mk7-Bs. instead, this month the hope is that Periapsis Co. gets us the booster from the March static fire to try test-firing again w/o thrust issues
Kerbal Space Agency
@KSA_MissionCtrl
the first of the WildCat-V engines was test fired today on the vertical stand. "Smoke" is steam from the water suppression system in the flame bucket. Check that engine bell going red hot! Lots of post-test analysis still to do & 2 more to go but key test item: did not explode
Kerbal Space Agency
@KSA_MissionCtrl
income is back in the red for June as expected but nearly as bad as CFO Mortimer feared, leaving us in good shape to push forward full-steam ahead for the remainder of the year. You can always review our latest monthly report on yearly finances here: docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
here's a look at the various improvements made to the Viklun orbital stage that will fly on the next Mk2 as early as late August. Quad thrusters are to keep the nose from falling too low, dual thrusters are in case it needs to be pushed down a bit more
Kerbal Space Agency
@KSA_MissionCtrl
R&D have concluded that however the Monolith is able to slowly discharge its energy, the understanding is beyond them. The potential for high density EC storage remains tho, and even with quick discharge rates could provide for emergency backup power to hungry spacecraft systems
Kerbal Space Agency
@KSA_MissionCtrl
KW Rocketry have come through on sched for delivery of the WildCat-V test engines, 3 minor design variants will be tested over the coming month for the production version to be finalized & delivered by the end of the yr so it can fly on the Ascension Mk3
Kerbal Space Agency
@KSA_MissionCtrl
If they can get out in time, their pressurized suit can help keep them afloat
Kerbal Space Agency
@KSA_MissionCtrl
the mock capsule is out the Kerblantic this week as MSV Aldeny works through more recovery drills but this time with primary crew Specialist Bob and backup crew Specialist Bill. Different protocols are obviously in effect here, like actually caring if the capsule is sinking...
Kerbal Space Agency
@KSA_MissionCtrl
this was an exciting week, make sure you didn't miss anything by check out our weekly Ops Summary on the website, where we have some speculation on the USI sale. We hope everyone has a relaxing weekend! kerbalspace.agency/?p=11062
Kerbal Space Agency
@KSA_MissionCtrl
staring towards the sun normally camera wouldn't see capsule that well, but so low to Kerbin light is reflecting back to illuminate it. Also did you see Mun? And Minmus?
Kerbal Space Agency
@KSA_MissionCtrl
have a look at the Gamma Ray Spectrometer retracting back into the capsule as it is detached from the lift stage and begins to orient for re-entry. 5FPS video was beamed back thx to remaining EC on the lift stage batteries, until atmo drag pulled antenna out of alignment
Kerbal Space Agency
@KSA_MissionCtrl
everyone is already looking forward to sending the last of our crew up into space and now the mission details are available on the Ops Tracker: ops.kerbalspace.agency. The timing of this mission could let Bob see something from space no kerbal has seen before
Kerbal Space Agency
@KSA_MissionCtrl
the view from 426km over the equator is not what you want to be seeing without proper shielding to protect you from being pelted by large amounts of ionized radiation. At apokee, the camera is looking back over the KSC landmass across the ocean to the Great Desert
Kerbal Space Agency
@KSA_MissionCtrl
here are the final moments we missed after LOS showing we actually came real close to losing the capsule - looks like we cut margins a little too fine in saving mass with smaller chutes - the capsule reached a safe landing speed only 50m above the sea surface!! 😬😬😬
Kerbal Space Agency
@KSA_MissionCtrl
the Mk1-A capsule has been returned to us for post-flight inspection along with what remnants of the heat shield didn't sink after it broke up after landing. You can now view the full telemetry data from the mission: docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
many thanks to NovaPunch for another finely-made K2-X lifter engine, which showed no issues during its static fire out on the vertical test stand today. It will now be placed into storage awaiting a mission assignment but also be rdy to backup the upcoming Mk1 & Mk2 flights
Kerbal Space Agency
@KSA_MissionCtrl
to be balanced @ MECO meant it had to be unbalanced @ launch, but the fins had enough bite even early in the ascent to keep it from flipping, altho we had hoped the extra forwards pitching moment would make it turn over faster when clearing the tower more than it ended up doing
Kerbal Space Agency
@KSA_MissionCtrl
a fact about the recent Ascension Mk1 mission we neglected to share was how the engine was mounted for the 1st time @ a fixed angle of just 0.0093° to overcome the rocket's desire to flip as it exits the atmo under thrust, low fuel changes CoM & no air to help fins hold attitude
Kerbal Space Agency
@KSA_MissionCtrl
low-alt crew have shipped out aboard MSV Lymun to head for bit.ly/Area_G0-XK8 & will return next week. We'd save some funds by letting them use our own ship MSV Aldeny but that's needed here so Bill & Bob can begin working their water recovery drills for July's mission
Kerbal Space Agency
@KSA_MissionCtrl
post-launch operations have concluded: flight data collected for analysis, Lead Engineer Simon reports no damage at the launch pad, capsule will be back at KSC tomorrow on a train from Umbarg. Congrats to all the teams on a successful return to rocket flight!
Kerbal Space Agency
@KSA_MissionCtrl
✨🎊 KERZZAH!! 🎉✨ \[0_o]/ MSV Aldeny has hauled the capsule out onto the deck & reports that it is beat up (this was its 4th flight) but intact. The heatshield however was found floating in pieces that will be collected to determine what happened. Overall tho - mission success!
Kerbal Space Agency
@KSA_MissionCtrl
we at least know the capsule was set for re-entry & if all went well it should be under chute around now for a safe splashdown ~125km downrange, right near where MSV Aldeny is stationed so we should have some news soon on how it fared. Post-launch ops are already in full swing
Kerbal Space Agency
@KSA_MissionCtrl
we have confirmation that preparations are underway to get the capsule clear of the lift stage and oriented for re-entry. It has ~40s to do what it needs to do before slamming into the atmo @ 2km/s+. Keep an eye on the Ops Tracker for comms blackout
Kerbal Space Agency
@KSA_MissionCtrl
coming up fast on re-entry in <2min. Here is where we will miss the LES, with a very late capsule release from the lifter at only 150km for max science grab, it would have done a much better job pushing clear than the RCS, but RCS should still do the job okay
Kerbal Space Agency
@KSA_MissionCtrl
belt was exited @ 342km! We did a near-perfect slice up across the middle as planned. Goo canisters will switch again when re-entering LKO. If you're not still watching the Ops Tracker, these vehicle state updates are being depicted as they happen ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
so far so good! Apokee is lower than planned, as expected. Hatch will now re-open to split the time back down through the belt between the GRS and RPWS. Peak exposure was recorded as 6.816rad/h so we came up a bit short of the densest region, which can be as high as 10rad/h
Kerbal Space Agency
@KSA_MissionCtrl
increasing levels of radiation beginning at 342km have triggered the capsule to withdraw the RPWS antenna and seal the hatch so the shielding efficacy can be tested. Magnetometer continues to collect data along with the Goo. Now we hope for no electronic glitches/failures
Kerbal Space Agency
@KSA_MissionCtrl
still racing upwards at over 1km/s, the rocket has passed 250km and out of Low-Kerbin Orbit. Goo canisters have switched exposure to prepare the samples that will be exposed to the high-radiation environment of the inner belt, which it should reach sometime in the next 2-3 mins
Kerbal Space Agency
@KSA_MissionCtrl
this image heralded the coming of science data, confirming the high gain antenna have deployed. You can just make out the north end of the Cape to the right of the antenna base. Apparently we also seem to have lost the LES tower at some point somehow?
Kerbal Space Agency
@KSA_MissionCtrl
MECO to w/in 2 sec! A relatively quick ascent with full burn heading almost straight up. Body rates are minimal & RCS will soon be brought online to stabilize. Flight computer is being purged of ascent instructions to load rest of mission code & kick off the science observations
Kerbal Space Agency
@KSA_MissionCtrl
rough start, rocket did not pitch over as quick as we would have liked, a bit bumpy through MaxQ but it should smooth out soon as we escape the denser lower atmosphere. Guidance is in phase 2 shallow curve mode & transition was without noticeable issue. Onward to space!
Kerbal Space Agency
@KSA_MissionCtrl
good engine start, nominal chamber pressures at throttle up, launch thrust good - we have LIFT OFF! The 13th Ascension Mk1 heads up to increase our knowledge of the hazardous inner radiation belt. Once clear of the tower engine will throttle to full, guidance will enable
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] coming up on one last poll at T-30s, if all good ascent telemetry should load shortly afterwards in the Ops Tracker ops.kerbalspace.agency. During the final seconds leading up to launch the following operations will occur:
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] the Automated Flight Control System has entered the terminal count sequence, where it takes control of the rocket for flight. Tower boom has swung away, leaving the spacecraft on internal battery power. EC drain rates are being monitored while RF comms check is underway
Kerbal Space Agency
@KSA_MissionCtrl
[L-3m] tank pressurization has begun to strengthen it & allow the rocket to stand rigid atop the launch clamp after the service structure has been swung away and the rocket is at the mercy of surface winds, which could always start gusting prior to lift off
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] we are GO for launch! Final polls completed with weather calm, Tracking Station dishes aligned, controllers ready, rocket primed for ignition, range clear & permission granted by Ops Director @DKerman_KSA. FTS is on internal power, service tower unlocked for retraction
Kerbal Space Agency
@KSA_MissionCtrl
be sure to bring up the Ops Tracker for live ascent telemetry - ops.kerbalspace.agency. If the rocket is on an off-nominal trajectory you'll see flashing indicators. Here are what they mean. Other values are more general "not good"/"very not good"
Kerbal Space Agency
@KSA_MissionCtrl
[L-13m] nitrogen gas is being onloaded from a small tanker left hooked to the service towers, which is used to keep the fuel tanks pressurized. This is done late in the countdown while the pad is permanently cleared of all crew to prevent any injury in the event of a tank rupture
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] RSO has shut down the range, Flight Termination System is now ACTIVE, engine is ARMED. All kerbs should be within designated viewing areas and have hearing protection. Masks are also required as pollen levels are currently HIGH in the area
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] we have reached final countdown procedures, which is the furthest point at which a launch scrub would have to be recycled back to. Hopefully tho any launch issues wouldn't force such a long re-count as our window today is only 15min
Kerbal Space Agency
@KSA_MissionCtrl
[L-45m] pad crews have evacuated for the final time (hopefully) but stand ready to return if any issues pop up during the launch rehearsal starting now. Weather balloon is only at ~11km, still rising towards the upper-atmosphere (18km)
Kerbal Space Agency
@KSA_MissionCtrl
radio transmissions relayed from MSV Aldeny by other maritime vessels plying the route between Umbarg and Sheltered Rock report sea conditions in the recovery area are within limits for hauling the capsule out of the water. Not just launch site weather that needs consideration
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h20m] another weather balloon is now on its way to the upper-atmosphere, timed to reach it prior to L-5min final polls to give us an update on wind conditions that could affect the rocket during ascent, such as shear or just high velocity that could push it around
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h30m] Lanalye reports launch controllers are standing by, rocket is healthy and primed for flight! Pad crew is back near the rocket again for final closeouts while the Range Safety Officer begins ensuring airspace and waters around KSC are clear & will remain that way
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h55m] launch crews are clearing out once again for controllers, now done with preliminary preflight, to run a thorough check of the engine and ignition system. After that, it's just some final checks of the rocket's secondary systems
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h40m] no issues during tanking, launch timeline remains on schedule as pad workers move back in to unhook the tanker and clean up. Controllers are continuing preflight operations while keeping a close eye on tank levels to ensure no leaks are present
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h55m] we have the GO from launch controllers that the rocket is woke and ready for tanking operations to begin. On the pad valves are opening to allow 7t of liquid fuel and oxidizer to flow into the 6.6m tall main fuel tank. Pad crew has cleared out to a safe distance
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h10m] tanker truck is standing by at the rocket with the pad crew preparing the service structure for fueling operations while controllers get on console to begin waking up the rocket and loading up the latest bit.ly/AFCS_KSA flight software operations
Kerbal Space Agency
@KSA_MissionCtrl
the guidance computer follows a quadratic fit formula to match the desired pitch curve when plotted against altitude, so the early steep curve won't also fit the later shallow curve and we need to switch at 10km from one to the other. Should be seamless. Should be...
Kerbal Space Agency
@KSA_MissionCtrl
during the ascent you'll see flight log readouts for "phase 1" and "phase 2" guidance. This is something new we are trying since the ascent profile has such a steep pitch change early and flat the rest of the way as opposed to a more gradual pitch over like for previous missions
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h40m] the lights are on in Launch Control as Flight Director Lanalye's Launch Team B reports for final briefing ahead of preflight operations. Here is the ascent and mission plan for today. We barely made the mass limit to get everything we wanted up into the inner belt
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h10m] Katgan has updated her forecast based on data from a recent weather balloon release & regional sources - we are now 80% GO for our launch time, still unsure about wind gusts but upper-atmo looks relatively calm. Launch operations proceeding as scheduled:
Kerbal Space Agency
@KSA_MissionCtrl
even though there is practically no room inside the capsule, Bob has still often joked the past couple of days that Jeb's whereabouts should be constantly monitored so that he wouldn't be able to sneak aboard for an extra ride into space
Kerbal Space Agency
@KSA_MissionCtrl
earlier at 2nd sunrise crews began to arrive at the launch pad to lower the rocket for late cargo onload of the Mystery Goo samples. It's not just a volatility issue, the samples are also radioactive & thus would have been a minor hazard to pad crew during rollout/WDR yesterday
Kerbal Space Agency
@KSA_MissionCtrl
MSV Aldeny has set out for the recovery zone ~135km to the east. A rather funny but legitimate concern on this mission was, we are sending the rocket nearly straight up - could Kerbin rotate enough to have it fall back down on us? Thankfully, it's not going high enough for that

that is Sarnus hanging out near Mun. The Ascension Mk1 can't reach either but the Mk2 has the potential to send payloads into orbit around Mun & Minmus or at least do fly-bys while the Mk3 should have the capability to send probes out past Sarnus (w/ gravity assists)
Kerbal Space Agency
@KSA_MissionCtrl
meteorologist Katgan has compiled her report for tomorrow & shows a 70% chance of good launch conditions, citing surface winds as the main issue. Of course, Wx forecasting is still a nascent concept that has the same probability of general accuracy... Regardless, Mk1 stands rdy!
Kerbal Space Agency
@KSA_MissionCtrl
based on data from past Progeny Mk6 flights through the belts, we have a very rough picture of their shape (details here: kerbalspace.agency/?p=9336) and the inner/outer belts are compressed by the kerbolar wind, so they are slightly closer to Kerbin's surface over the dayside
Kerbal Space Agency
@KSA_MissionCtrl
WDR came up with no GSE issues, all launch readiness reports have been signed off on by @DKerman_KSA, rocket is prepped for launch procedures to begin tomorrow @ 17:50 UTC. Launch window is near-instantaneous mid-day cycle as we want the deepest inner belt penetration possible
Kerbal Space Agency
@KSA_MissionCtrl
we're sticking to a familiar timeline, and as the sun sets the rocket is tanked up to capacity so the launch team can perform a wet dress rehearsal to ensure all ground support equipment is functioning properly. Rocket propellants will then be drained back
Kerbal Space Agency
@KSA_MissionCtrl
Mk1 rollout was successful and before it will be lifted vertical for mounting to the engine clamp and service towers a comms check was done for both high-gain antennas. Data rates are good, they will be folded back down & the rocket mounted for fueling prior to WDR

@KSA_MissionCtrl
our recovery ship MSV Aldeny has made the ~900km journey started Wednesday from its berth in Sheltered Rock, from Jeb's recovery, to port in Umbarg. Over the weekend it will engage in drills offshore here at KSC to get the crew back up to speed for capsule recovery
Kerbal Space Agency
@KSA_MissionCtrl
here is a closer look at the great job the engineering team did cramming batteries into the decoupler for this upcoming mission, which was absolutely necessary to power all the science equipment and beam the data home. More details from @DKerman_KSA: twitter.com/DKerman_KSA/st…
Kerbal Space Agency
@KSA_MissionCtrl
Flight Director Lanalye has been in Launch Control drilling the Launch Team B hard all week. Normally handling Progeny flights, they need to be brought up to speed on Ascension operations. Launch Team A is prepping in the Astronaut Complex to manage Bob's mission next month
Kerbal Space Agency
@KSA_MissionCtrl
the 2nd K2-X engine from the order placed back in Feb has arrived at KSC. It will be static fired next week after the Mk1 mission and then will serve as backup to Bob's mission and the 2nd Mk2 mission before being assigned its own flight - likely to deploy commsats on a Mk2!
Kerbal Space Agency
@KSA_MissionCtrl
the capsule was stacked atop the lifter today so the rocket can be lowered horizontal for final closeout checks the remainder of this week. Launch prep remains on schedule for lift off next Tuesday. To see how we assemble our rockets, check out this album: flickr.com/photos/kerbal_…

the ATN is not part of KSA so why do we care so much about Alaba & the study of its orbit? Because this is what our future spacecraft will be doing! Being able to accurately plan ahead multiple encounters with large bodies will be integral to future planetary system exploration
Kerbal Space Agency
@KSA_MissionCtrl
Here is a look at the new long-term propagation, going out 15 encounters over the next year. Alaba seems to yo-yo instead of escape, possibly coming back to crash into Kerbin or Mun. Hi-res 4k plots available:

a hazy start to the 3rd day cycle at sunrise earlier, looking out over the KSC campus from Building B of the Support Village. Fog off the ocean occurs often & is why we usually don't launch at sunrise, in addition to just having better visibility for post-launch video analysis
Kerbal Space Agency
@KSA_MissionCtrl
this was the 1st attempt to fire a recast booster, using the same casing from the test firing done back in Feb. While a significant setback for our future hopes of reusable SRBs it wasn't unexpected & plenty of data was collected to help rectify whatever issue(s) are uncovered
Kerbal Space Agency
@KSA_MissionCtrl
cleanup & emergency crews are finishing up around the horizontal test stand, which suffered an explosion of the Boostertron II that was undergoing test fire today. How well it withstood the failure remains to be seen but all safety protocols were followed & no injuries reported
Kerbal Space Agency
@KSA_MissionCtrl
scientists over in the R&D labs are getting Mystery Goo samples rdy for containment so they can be launched into space aboard a Mk1-A capsule later this year. Goo has been launched into space before (with Progeny rockets) but this will be the 1st use of radial-mounted containers
Kerbal Space Agency
@KSA_MissionCtrl
we have a new static display out on the KSC main lawn for visitors to check out starting this weekend! The Ascension Mk2 & its payload Kerbin I, 1st to orbit Kerbin, join the Ascension Mk1 that carried up the 1st kerbal to space & the Progeny Mk4 that 1st made it past 70km
Kerbal Space Agency
@KSA_MissionCtrl
sea cabling has connected the two ground stations running from Kravass and the Kongo Research Base to their coasts. Future orbital missions will now be able to send & receive commands through the Kongo ground station, which will only be used for low-Kerbin orbit
Kerbal Space Agency
@KSA_MissionCtrl
first major hurdle of our Ascension program reassessment is out of the way with the flight analysis for Jeb's mission now published. Despite the mass issue, several new mission aspects saw positive results & puts us in a good position to move forward: kerbalspace.agency/?p=10884
Kerbal Space Agency
@KSA_MissionCtrl
ensuring that our upcoming missions are successful & also doing everything possible to allow us to begin accepting commercial payload contracts is critical to our financial health this year. We could run out of money if there are too many unplanned setbacks due to large failures
Kerbal Space Agency
@KSA_MissionCtrl
CFO Mortimer has published our latest financial report, which shows us eating - nay, gorging on the profits we made in Feb thanks to the orbital Kerbin I mission. Another reason to pause ops - rocket flights not yet sustainable. Full report: docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
the final Boostertron II test article was successfully fired today. While we will eventually order new ones for the 1st Ascension Mk3 flight, further testing will be done on reusing these initial production boosters. The 1st one fired back in Feb is scheduled to arrive this month
Kerbal Space Agency
@KSA_MissionCtrl
VAB will be making use of the down time to upgrade their spin table to handle payloads larger than 0.625m in diameter, the first of which could be the Extremis I probe that is still under design twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
with the rocketry programs suspended, the Tracking Station will undergo maintenance to get a head start on the upgrades that will be needed towards the end of this year when we hopefully start lofting communications satellites into orbit
Kerbal Space Agency
@KSA_MissionCtrl
good static fire of the K2-X engine for the unkerbed Mk1 mission was carried out today. Although it will not be used as soon as planned due to the operational suspension, testing it now ensures any major defects could be addressed to not further delay the already delayed mission
Kerbal Space Agency
@KSA_MissionCtrl
the final production test Boostertron II has arrived and will be static fired out on the horizontal test stand later this week. Testing 4 boosters for any failures equals the max number we could someday strap onto an Ascension Mk3
Kerbal Space Agency
@KSA_MissionCtrl
things will be slowing down for a while, but we do expect to clear out the backlog quickly starting Jun/Jul to remain as close as possible to our projections made at the start of the year. We waited to hear of more Chikelu news but nothing yet kerbalspace.agency/?p=10850
Kerbal Space Agency
@KSA_MissionCtrl
Operations Director @DKerman_KSA rejected Lead Engineer Simon's resignation today. He may have made mistakes but this just shows he is willing to accept them and we expect him to move forward with us and make the most of the experience he has gained over the past 3+ years
Kerbal Space Agency
@KSA_MissionCtrl
TL;DR - several recent minor oversights both in the rocketry & aircraft programs have begun to worry upper management that we are on course to make a catastrophic error in a future mission. Time to slow down before a major oversight occurs with horrible consequences
Kerbal Space Agency
@KSA_MissionCtrl
a tough decision has been made. The Kerbal Space Agency will be suspending launch operations for at least the next two months while we reassess Ascension & Progenitor program management. More details in this press release from @DKerman_KSA: kerbalspace.agency/?p=10854
Kerbal Space Agency
@KSA_MissionCtrl
the final K2-X engine from the order placed back in Aug 2019 has arrived. It will be static fired next week and then assigned to the Ascension Mk1 mission in May that will carry the unkerbed capsule up through the radiation belts
Kerbal Space Agency
@KSA_MissionCtrl
here's a better look at Mun setting from Captain Jeb's mission. Breathtaking! The redness comes from light bending through the atmosphere, seen as just a thin layer of protectiveness. Really puts things in perspective
Kerbal Space Agency
@KSA_MissionCtrl
more income for the Ascension program thanks to new protocols established this year by Lead Scientist Cheranne to allow us to collect additional data even for experiments run on previous missions. Helpful, but Ascension still needs to start picking up contracts this year
Kerbal Space Agency
@KSA_MissionCtrl
altho Jeb's actions did not endanger the mission, Flight Director Lanalye & @DKerman_KSA agree that he should be reprimanded. Lanalye wanted to kick him out of a rotation *and* make him ineligible for 1st in orbit, but Drew has decided he only loses the chance to be 1st in orbit
Kerbal Space Agency
@KSA_MissionCtrl
Capsule photos from Jeb's mission!

today Jeb got a hero's parade in his home cavern of Ockr. In his public address he spoke of how beautiful and pristine Kerbin looked from above and how he hopes the efforts to recolonize the surface that are gaining more & more momentum work to ensure it stays that way
Kerbal Space Agency
@KSA_MissionCtrl
after extensive examination Jeb was given a clean bill of health & released by the medical team at Sheltered Rock. He'll be sharing a meal with the Presider today, has another engagement tomorrow & then will be traveling back to KSC next week after some well-earned personal time
Kerbal Space Agency
@KSA_MissionCtrl
telemetry data from yesterday's mission is now available. What we thought was transmission issues in the ascent telemetry turned out to be a timing issue on the rocket that is still being investigated, only seemed to affect logging thankfully docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
post-launch and post-mission ops are all wrapped up, everyone is looking forward to a nice relaxing weekend before the final prep for next week's launch pushes crews back into high gear. Recap this week's events here in our Ops Summary: kerbalspace.agency/?p=10830
Kerbal Space Agency
@KSA_MissionCtrl
Jeb was just congratulated personally over radio by the Presider and will also get a chance to be honored in person when MSV Aldeny docks in Sheltered Rock tomorrow, now making best speed out of the recovery zone after also tracking down and collecting the heat shield
Kerbal Space Agency
@KSA_MissionCtrl
sun has set but the capsule has been recovered w/o issue thx to night exercises as part of standard mission training. Here's a photo Jeb took while waiting. Photos from space will also be released in the coming days. Congrats to all the teams on another successful kerbed mission!
Kerbal Space Agency
@KSA_MissionCtrl
Jeb has confirmed he is afloat, capsule is not sinking nor taking on water. While he can unstrap & stand on the seat to stretch a bit he'll have to wait for MSV Aldeny to haul him out of the water before he can exit the capsule. Taking a swim is for emergencies only. Even for him
Kerbal Space Agency
@KSA_MissionCtrl
SPLASHDOWN! Welcome home to our latest space voyager - Captain Jeb! While his rash action failed at allowing him to break Val's records for altitude & duration as he'd hoped, leaving him slightly unsatisfied, he readily admits the experience was still worth it.✨🎉 Kerzzah! 🎊✨
Kerbal Space Agency
@KSA_MissionCtrl
full chute deployment, confirmed by MSV Aldeny ~20km away able to full-frame it this time with a telephoto lens as capsule drifts down at ~6m/s in the soft glow of sunset. Flotation collar is armed & heat shield will be dumped just before hitting the water
Kerbal Space Agency
@KSA_MissionCtrl
cheers & applause in Launch Control as Jeb contacts us to confirm chute deploy! Chutes are reefed & continue to decelerate him but the worst is over, similar to Val he dealt with +10G (11.2 max) for 6 seconds. MSV Aldeny hasn't had much time to get underway but are <30min out
Kerbal Space Agency
@KSA_MissionCtrl
blazing through the atmosphere now, we expect plasma blackout to occur at any second (ops.kerbalspace.agency will show it happening) and last up to 30-60s, after which we should get confirmation of chutes popping. Descent profile at reentry was nominal
Kerbal Space Agency
@KSA_MissionCtrl
without causing any more hassle Jeb has the capsule prepped for re-entry, heat shield facing forward & LES decoupled. He will also place the capsule into a roll to help ensure the radial chutes do not get cooked. He's been looking forward to this - the centrifuge can't sim it
Kerbal Space Agency
@KSA_MissionCtrl
with awe in his voice Jeb says he just witnessed a beautiful sight watching Mun set, although that's really from his capsule falling back down and now passing through 200km he has to reluctantly leave the window and begin preparations for re-entry
Kerbal Space Agency
@KSA_MissionCtrl
and Jeb continues to not earn any points today when he refuses the suggestion to decouple the LES tower, saying he finds the extra effort to maneuver the capsule makes it easier to control. That is within his purview, however, as capsule commander. Coming up on apokee in <30s
Kerbal Space Agency
@KSA_MissionCtrl
Jeb is unstrapped & floating in 0G, taking photos out the capsule window. Flight surgeon says all vitals are nominal. Lanalye is still livid but at this point in the mission there is no other need for the LES' alternate backup uses & splashdown zone shifted by only ~20km
Kerbal Space Agency
@KSA_MissionCtrl
LES push motors were triggered from within the capsule shortly after RCS push, increasing apokee to 244km. This was *not* a planned or approved action & FD Lanalye is turning purple. Jeb is actually trying to convince her that he accidentally bumped the (covered) switch
Kerbal Space Agency
@KSA_MissionCtrl
MECO 3km short of target altitude, rocket is a bit shallow on ascent with an apokee of 206km instead of 239km as planned. Capsule has been released & will push away on RCS thrust, then Jeb will flip over to look back at lifter & confirm good sep and increasing distance
Kerbal Space Agency
@KSA_MissionCtrl
Jeb says he's "loving the real deal" as flight continues into the upper-atmosphere w/ only minor "roll-shake" turbulence. Thrust is <50% but pitch authority remains nominal. Passing above 30km Jeb will soon get a kick as the engine throttles to full @ 40km ASL in the next minute
Kerbal Space Agency
@KSA_MissionCtrl
smooooth flight so far, engine performance nominal. Guidance right on track. Telemetry is dropping in & out but Jeb's calling out good instrument readings, all systems nominal. Rocket is through MaxQ and about to go supersonic, where the ride could start getting a little bumpy
Kerbal Space Agency
@KSA_MissionCtrl
LIFT OFF of the 12th Ascension Mk1 carrying Captain Jebediah up on his first trip into space! As the rocket clears the tower guidance will enable, throttle will push up to and hold 1.5 TWR. Once Jeb stops laughing maniacally he should begin calling out instrument readings
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] back to the final seconds once again. Flight surgeon reports Jeb's heart rate is elevated as expected, no doubt as he asks himself - "can this finally be happening??" Tune in now to find out live if T-30s polls are GO via streaming telemetry: ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] "GO! GO! GO!" yelled Jeb over the comms when asked for his status to move into terminal count, a play on the other word we do *not* want to hear called out three times at any point in the next two minutes. Capsule power internal, comms RF. EC monitoring active
Kerbal Space Agency
@KSA_MissionCtrl
yellow flag just popped up next to the wind readings on the main display at Launch Control. Everyone's trying to not look at it but of course it can't be ignored. If winds continue to increase and it goes red... no, we're not thinking about it. But we're still watching it
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] final general polling has come back GO from all stations! Jeb is switching his suit over to internal capsule systems while the FTS does the same. Rocket fuel tanks will soon add pressure for rigidity to prep for service boom retraction. A hush falls over the crowd outside
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] rocket is ARMED for ignition, LES & FTS both ACTIVE. Any incursion to the airspace exclusion zone, downrange ascent marine corridor or 500m ground blast safety radius will immediately halt the count. You don't want to be the one to make Jeb even more frustrated
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] with the launch team still working no issues, fair weather both here and in the recovery zone where MSV Aldeny sailed back to yesterday, we have a GO for final countdown procedures to commence. Launch pad is evacuated and RSO is preparing to close the range
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h30m] pre-launch ops continuing without issue, preparing now to send up the second weather balloon for a final check of upper-level conditions. Winds are picking up on the surface but trending within expected limits. Jeb's latest comment is "can we get going already?"
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h55m] we have a GO for tanking ops. Flight computer is online and Monolith chilldown was performed earlier today to withhold the formation of storms. FD Lanalye is making sure no one is treating these operations as "routine", so soon from last time. Complacency is dangerous!
Kerbal Space Agency
@KSA_MissionCtrl
we've finally allowed the surface map to move in twice the current zoom level to make it easier to see the rocket moving & mouse over markers in the early ascent stages. A future orbital mission will provide us with higher detail hopefully in the next year or so
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h20m] crew loading was without issue. Jeb is aboard while Bob waits in the Astronaut Complex. Rocket is being raised back to vertical for mounting and tanking. Flight briefing will be underway soon and there are no changes from last week: twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
[L-5h10m] launch prep underway with a favorable report from the weather balloon sent up earlier to check on upper-level winds. Surface conditions remain green as well altho attention still being paid to winds from a high pressure system offshore. Countdown remains the same:

once again @DKerman_KSA received launch readiness reports, reviewed them and gave the GO for tomorrow's launch attempt! Weather forecast is 80% GO with surface winds off the water being the main concern. If winds aloft are also looking good, pre-launch ops will begin @ 11:05 UTC
Kerbal Space Agency
@KSA_MissionCtrl
drainback of remaining propellants is underway after a successful static fire. We lit the engine, ran it to launch thrust & for good measure throttled it up to ascent TWR of 1.5, held it for 10s then went to full for 30. Not a full burn but enough to feel confident about tomorrow
Kerbal Space Agency
@KSA_MissionCtrl
Jeb's Ascension Mk1 has been rolled out to the pad to be hooked up & fired. We don't plan to do this before every launch moving forward, but in this case with time already wasted we certainly don't want to go through all the trouble again of reaching T-0 to suffer a similar issue
Kerbal Space Agency
@KSA_MissionCtrl
flight overview and analysis has been released for the Ascension Mk2 orbital mission - kerbalspace.agency/?p=10779 we look forward to flying the second Mk2 towards the end of Q2 2020, carrying a technology demonstrator for future comm sats
Kerbal Space Agency
@KSA_MissionCtrl
working through the weekend, the VAB crew have completed the engine swap and are closing out the rocket today with roll-out scheduled for tomorrow. This will be followed by a static fire on the launch pad to confirm that the engine can achieve proper launch thrust
Kerbal Space Agency
@KSA_MissionCtrl
with more time now before the mission launches, Jeb has implored the design team to see if they can't go back & squeeze out a bit more altitude so he can break Val's records. Ascension project management declined the ascent review, saying mission is locked twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
Lead Engineer Simon reports the engine for Jeb's rocket developed a bad fuel flow sensor in the time between static fire and launch. They will replace the part, seek higher quality from the manufacturer, and have the engine ready again for Bob's mission in April
Kerbal Space Agency
@KSA_MissionCtrl
the flight crew have physical exercises from the medical team as well as textbook training to keep them busy & tip-top this week. Flight Director Lanalye is keeping her controllers on task as well, with more drills scheduled all the way up to roll-out later this week
Kerbal Space Agency
@KSA_MissionCtrl
you always hope for the best when testing but that's usually not enough to keep things from going wrong. Thankfully #OTD in 2019 no actual crew were aboard to be injured and the LES performed perfectly as designed later in the year to save Cpt Jeb's life twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
💫 KERZZAH! ☀ - 12 times we have now traveled around Kerbol since the KSA was founded - at 1,025,316,660.821km distance traveled we are just 3 light minutes shy of a light hour's travel time over the same distance. Spaceship Kerbin is tooling along at a constant 9.28km/s
Kerbal Space Agency
@KSA_MissionCtrl
a bummer that we were unable to return to kerbed space flight this week but heads are up and looking forward to next week's attempt! More on that and everything else that transpired this week in our Ops Summary: kerbalspace.agency/?p=10765
Kerbal Space Agency
@KSA_MissionCtrl
still no diagnosis on Jeb's engine, but luckily we don't have to wait for one because the engine for Bob's flight is tested and ready. Lead Engineer Simon says they can swap it for another launch attempt next week, now targeting lift off on 3/20 @ 16:15 UTC
Kerbal Space Agency
@KSA_MissionCtrl
actually it will be the Ascension Mk1 that gets to continue Mystery Goo studies. The flight in May will carry two radial goo canisters on the side of the unkerbed Mk1 capsule up through both radiation belts and out of the magnetosheath twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
medical team gave Jeb his games back while he remains stuck in quarantine. Although they tend to get him a bit worked up at times, better than having him depressed thinking about the continued setbacks in his attempts to get up into space
Kerbal Space Agency
@KSA_MissionCtrl
launch activities are complete, a frustrated Jeb is back in the AC, rocket is back in the VAB and MSV Aldeny is making for port in Sheltered Rock. Ascension team will convene tomorrow to discuss options for another attempt to allow time for initial engine inspection
Kerbal Space Agency
@KSA_MissionCtrl
propellant drainback has been completed, service arm will now be swung away again so the rocket can be lowered for Jeb to egress from the capsule and head back to the Astronaut Complex. He and Bob will remain in quarantine until a decision is made on the next launch attempt
Kerbal Space Agency
@KSA_MissionCtrl
we got Jeb calmed down, rocket is once again safed, including FTS & LES. We have to rehook the service boom to drain propellants before the rocket can be lowered so Jeb will have to stew out there for a while yet. At least hookup means he has continuous power for climate control
Kerbal Space Agency
@KSA_MissionCtrl
[ABORT] "NOOOOOOOOOO!" came Jeb's holler over the comms, followed by banging noises, as he felt the rumble of the engine subside. AFCS has still failed to detect proper lift off thrust and we will have to unfortunately scrub today's launch & rollback for a good look at the engine
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] final 30s polls coming up, same automated sequence will follow as before. If you are tuned into the Ops Tracker keep a close eye on the telemetry data - it does show current TWR!
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] back in terminal count, AFCS once again has control. Power levels have continued to drop since first terminal count but we still have enough battery life to give this another shot. Fuel usage from 1st attempt won't have any large impact on ascent plans
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] once again back to general polls, all GO. Rocket is rearmed for ignition & AFCS is back to waiting for terminal count. Everything will proceed as before (except pressurization, already completed) and hopefully this time the engine will perform as expected
Kerbal Space Agency
@KSA_MissionCtrl
work is underway to reboot the flight computer & reload op code to make sure that wasn't an issue. Lift off now targeted for 16:15 UTC. This is one of the faster launch recycles that controllers will have to perform but FD Lanalye is confident in her team's training
Kerbal Space Agency
@KSA_MissionCtrl
no one is finding anything unusual in the data leading up to lift off so we will try again. K2-X cannot be relit in flight but on the ground we can restart it as many times as needed. If this 2nd attempt fails tho launch will be scrubbed for a more detailed engine investigation
Kerbal Space Agency
@KSA_MissionCtrl
rocket engine is safed, clock reset to L-5min. Jeb is of course frustrated & altho rocket would have still gone upwards at launch w/1.18 TWR, failure to set thrust properly could mean it also doesn't throttle up enough later in flight to make it to space, which would be a waste
Kerbal Space Agency
@KSA_MissionCtrl
[ABORT] AFCS threw an automated hold just before lift off when it did not detect proper launch thrust setting. RSO is working with Jeb to safe the rocket while controllers take a close look at the telemetry data to determine whether this is an issue that can be overcome w/o scrub
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] tune into the Ops Tracker now if you're not already! ops.kerbalspace.agency primary poll at T-30s coming up & real-time ascent telemetry should load shortly after that. Here is the final automated event sequence prior to launch:
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] all remains GO as we enter terminal countdown, AFCS has assumed control of the rocket, service boom detached & capsule now on internal power, life support and RF comms. EC drain being monitored and comm checks underway. Jeb has tasks to keep him occupied up to launch
Kerbal Space Agency
@KSA_MissionCtrl
[L-3m] prelim fuel tank pressurization underway to increase rigidity & allow the rocket to stand on its own atop the engine support clamp once the service tower boom swings away in the next minute. Jeb will call out his own GO shortly to confirm he is prepped for terminal count
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] Wx: GO; Range: GO; Flight: GO; Tracking Station: GO; Downrange Tracking: GO; Recovery: GO; Ops Director @DKerman_KSA: Launch permission granted! 🚀GO ASCENSION🚀 FTS power internal, service tower boom unlocked for retraction, AFCS ready for terminal count
Kerbal Space Agency
@KSA_MissionCtrl
Bill is walking Jeb through a final suit integrity check followed by the switch over to internal capsule life support ahead of terminal countdown. Controllers are glued to their monitors, making final checks as well in prep for FD Lanalye to conduct final general GO/NO GO polls
Kerbal Space Agency
@KSA_MissionCtrl
[L-13m] late onload of pressurization gas underway. Modifications made to the upper liquid fuel bulkhead moved the nitrogen tanks up higher and necessitated that we also raise the capsule up a bit as well, creating a small enshrouded interstage gap
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] RSO has confirmed airspace is clear out to our 20km exclusion zone & ascent corridor over the water is empty of vessels. Rocket Flight Termination System is ACTIVE, engine ignition ARMED. Jeb's heart rate slightly elevated as he rapidly taps his foot. Impatience, he says
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] Kat & her weather team confirm surface conditions remain green throughout our daytime launch window & we have a GO to enter into final countdown! Launch control resetting after a clean rehearsal to link back up with the live rocket. Jeb is humming contently to himself
Kerbal Space Agency
@KSA_MissionCtrl
[L-45m] launch rehearsal is underway to uncover any final issues that may have evaded the teams during preflight. Launch site is locked down & cleared of all vehicles except for the small tanker truck carrying the nitrogen pressurization gas
Kerbal Space Agency
@KSA_MissionCtrl
checking in with MSV Aldeny out in the recovery zone and in range of Ockr Relay they confirm weather and sea conditions remain good for splashdown. We're still evaluating ascent accuracy and whether for future missions to have a land target to use in event of rough seas
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h20m] another high-altitude balloon has been released so we can get updated information on upper-level conditions before the general polling at L-5min. Wind shear constraints are a bit tighter due to the new extended interstage between the capsule and fuel tank
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h30m] preflight wrapping up on schedule with 0 issues, rocket is healthy & ready to go! Launch site lockdown underway for final evacuation as Range Safety Officer begins final check with the SkyWatch team of the waters and airspace surrounding KSC
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h55m] another planned pad evacuation underway as preflight moves into engine and ignition checks. So far issues board remains clear, valve problem from earlier this week has been fixed. Jeb is now out of things to do except chit-chat with Bill on CapCom
Kerbal Space Agency
@KSA_MissionCtrl
"Rolling left. Check?"
"Check"
"Pitching up. Check?"
"Check"
....
call/response continues between Jeb & the pad crew as he manipulates the manual controls & they confirm movement. Rocket may operate under automated control but the kerb aboard still has plenty of preflight tasks

@KSA_MissionCtrl
[L-2h40m] tanking ops wrapped up on schedule and rocket is now 7t heavier with liquid fuel & oxidizer, bringing its total mass to 10.814t. Preflight operations are now continuing while the pad crew moves back in to clean up and prepare to lock down the launch site
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h55m] we have a GO to begin tanking operations. Monolith chilldown in effect, no change to atmospheric pressure. Launch Escape System is armed & Jeb actually knows from past experience that if the tank happens to blow up he'll be safe from harm
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h10m] remounting was successful & w/o issue allowing the launch team to begin preflight operations, waking up the capsule computer and onloading flight instructions, including a new comms protocol (bit.ly/AFCS_ChangeLog) Jeb also has work to do setting up manual controls
Kerbal Space Agency
@KSA_MissionCtrl
Jeb's rocket is using the old-style fins but they are also the newer lighter versions, so his rocket masses 59kg less than Val's. It's amazing how much difference that can make, his ascent profile required completely different angle & power settings to still land near Ockr Relay
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h40m] rocket mounting proceeding well, Flight Director Lanalye's A team of launch controllers is now assembling for final mission briefing. Like past kerbed flights, Jeb's mission will primarily be to measure physical response to 0G & re-entry forces
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h20m] back on track as capsule hatch is sealed and pad crew begins to raise the rocket back to vertical for remounting. Bill is at the pad plugged into the capsule to maintain contact with Jeb during the process, as capsule comms to Launch Control are not yet online
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h41m] crew loading underway a few minutes late - FD Lanalye had given the pad crew special instructions to *not* allow Jeb to climb up on the rocket again. After his attempts were foiled he then refused to pose for a new photo and began to climb into the capsule

[L-4h57m] crew shuttle departed on schedule 3 min ago and is now passing Launch Control on its way to the pad with Jeb aboard. Bob will remain in the Astronaut Complex suited up and ready to replace Jeb at any time. According to Jeb that time would be "over my dead body!"
Kerbal Space Agency
@KSA_MissionCtrl
[L-5h10m] weather balloon released earlier shows upper level atmospheric conditions to be within limits, surface forecast remains 90% GO. Rocket is back horizontal and capsule is awaiting crew ingress. Here is today's launch timeline, expect updates at each milestone
Kerbal Space Agency
@KSA_MissionCtrl
the flight crew are being roused from bed, will be given their choice breakfast and then proceed to get suited up. They aren't the only ones up super early - weather team is out to release a high-altitude balloon and pad crew is heading out to lower the rocket
Kerbal Space Agency
@KSA_MissionCtrl
storm has blown past, not over. Weather for tomorrow is looking 90% GO. Final readiness reports were reviewed & approved by @DKerman_KSA. Crew remains healthy & Jeb is chomping at the bit. Launch prep begins tomorrow @ 10:35 UTC if weather conditions hold
Kerbal Space Agency
@KSA_MissionCtrl
latest report from the KWS shows that we will likely get hit by the outer bands of the storm so launch has been delayed further until tomorrow, now targeting lift off @ 15:45 UTC. Further delays are possible - we will see what happens with the weather later today

Kerblantic storm is growing and heading in our direction. Models show it could swing wide - we won't have a better idea until early tomorrow so we've pushed the launch back to the next day cycle, now targeting lift off at 20:42 UTC. All other launch aspects are GO!
Kerbal Space Agency
@KSA_MissionCtrl
wet dress rehearsal was good and identified a minor valve issue in the GSE that will be rectified by tomorrow so no hold up for launch. Although propellants are stable tanks have been drained so the rocket can be lowered again for crew loading
Kerbal Space Agency
@KSA_MissionCtrl
all ground stations, dishes and antenna that will be supporting the upcoming mission have undergone comms checks and are good to go. One of our Tracking Station dishes is undergoing routine maintenance but the other two will be able to provide primary/backup requirements
Kerbal Space Agency
@KSA_MissionCtrl
upon the pod you can see 1 of 2 radial parachutes that will provide triple redundancy. Main chutes have never failed & can land the capsule with only 2/3 deployed but radials can be used in partial main failure or even in complete main failure 1 is enough twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
it's the crack o' dawn and the Ascension Mk1 is on its way to the launch pad, where it will be erected and later today tanked up as part of the wet dress rehearsal as final steps are taken today to prepare the Space Center for launch tomorrow!
Kerbal Space Agency
@KSA_MissionCtrl
KWS has dispatched another flight from Sheltered Rock as the storm out to sea continues to develop. Not sure at this time whether or not it will head our way but if so it could disrupt our launch plans. They will be keeping us informed of the data that is collected
Kerbal Space Agency
@KSA_MissionCtrl
our recovery ship MSV Aldeny, docked in Umbarg, has begun the ~30hr journey out to the planned landing zone. Given how close we were with Val's landing, we hope launch modeling improvements means we get a much better shot of Jeb's capsule descending under chutes this time
Kerbal Space Agency
@KSA_MissionCtrl
the Ascension Mk1 passed load checks last week and was put back to horizontal for final checks consisting of a 26-page closeout process that was finished today for tomorrow's launch readiness review. It has been loaded up onto the carry vehicle to prepare for tomorrow's rollout
Kerbal Space Agency
@KSA_MissionCtrl
the doctors finally had to take away Jeb's video games - not because he wasn't getting enough sleep but his stress levels were staying quite high. He's a bit of an angry gamer... Bob in contrast has been working on his meditation twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
Kerbin Weather Society called for a flight to investigate a gathering storm out on the Kerblantic but with Jeb in quarantine and no additional flight crew to assist Val we had to tell them to send the crew out from Sheltered Rock instead. Good thing we own our aircraft...
Kerbal Space Agency
@KSA_MissionCtrl
although the flight crew is quarantined inside the Astronaut Complex they are not simply confined to quarters. This is a dedicated section adjacent to the medical wing which also has a viewing room to allow friends & family to talk to the crew before their mission
Kerbal Space Agency
@KSA_MissionCtrl
Jeb & Bob are both in quarantine, sequestered in the Astronaut Complex and visited only by the medical staff, who are collecting baseline readings and making sure both remain in good health and are getting enough rest. They haven't taken away any of Jeb's games yet tho
Kerbal Space Agency
@KSA_MissionCtrl
everything continues to look good for Cpt Jeb's mission next week, also learn more about the new WildCat-V lifter engine and the recently-announced Progeny MK7-B mission in our Ops Summary: kerbalspace.agency/?p=10750 - a good weekend to all!
Kerbal Space Agency
@KSA_MissionCtrl
once again Jeb comes out of sim training with the most mission successes. He says he wishes he and Val were a permanent crew pairing so they could go head to head more often (Jeb is Val's backup in the rotation). Bob may have lagged, but still learned from all his mistakes
Kerbal Space Agency
@KSA_MissionCtrl
as mission training nears a close Flight Director Lanalye has commented that she's pleased to see Jeb & Bob getting along better now, although there have still been a few instances where Jeb's sense of humor bordered on inappropriate twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
final integration of Jeb's Mk1 is underway today & tomorrow. Although the new fins are both lighter and cheaper his rocket will sport the older ones as the first use of the newer ones actually replaced these, so we had them as spares & sub-orbital ascent profile is steep
Kerbal Space Agency
@KSA_MissionCtrl
tickets are going fast for this upcoming launch that will see kerbals returning to space! There will be no VIP visitors and all viewing sites at KSC will be available. As always the non-ticketed areas are first-come first-serve and overflow will be held at the Support Village
Kerbal Space Agency
@KSA_MissionCtrl
we were extremely excited by some of the other designs but chose to be conservative and go with a small upgrade. Now that we have more funds to funnel into R&D, the other agencies are continuing to work on the rejected designs for another review later this year
Kerbal Space Agency
@KSA_MissionCtrl
proposals from Kerbodyne, AEIS, KNES, BDB, NovaPunch & KW Rocketry have all been considered and we have finally chosen to award our new Ascension Mk2/Mk3 engine contract to the KW WildCat-V. It is a dedicated lifter engine meant to be paired with a 2nd-stage vacuum engine
Kerbal Space Agency
@KSA_MissionCtrl
the K2-X engine for Spc Bob's mission had a successful static fire out on the vertical test stand today. We continue to target an early April launch to get our last astronaut aboard a rocket and have a space ribbon pinned on them afterwards
Kerbal Space Agency
@KSA_MissionCtrl
while it's disappointing that we can't determine how far off we were in our prediction, ultimately the stage was always fated to crash back to Kerbin even originally & we are just glad it didn't come down atop any of the few surface installations along its path - including us!
Kerbal Space Agency
@KSA_MissionCtrl
still no report of bolides that could have matched the Viklun stage's orbital plane. Cameras will remain in place just for the sake of general observation but at this point we are pretty confident it fell either in the ocean or between DSN Central & Arekibo (rough approximation)
Kerbal Space Agency
@KSA_MissionCtrl
earning the orbital prize purse not only made Feb a profitable month but secured our financial future - at least through the remainder of this year. By that time we hope to be placing commercial payloads into orbit! Full financial report: docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
Mk1 flight crew have begun a final week of intensive sim training that also involves the entire launch control team. Flight Director Lanalye very much enjoys this last training segment as she works to come up with all sorts of scenarios to attempt to "kill" the crew
Kerbal Space Agency
@KSA_MissionCtrl
still no word from any surface installations on Viklun's return. Some fireballs spotted but none tracked from the proper orbital plane. Well shucks, we were really hoping for our prediction to be accurate w/in a day. Still possible it came down between Arekibo/DSN Central though

Captain Jeb will get his second chance to go to space next month! Mission has gotten its final approval, launch date has been decided for 3/11 @ 14:40 UTC. More information on the mission can be found at the Ops Tracker - ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
Kerbin I has come home! There was a lot more of the probe that survived re-entry than expected, which will make for interesting post-flight analysis. Lead Scientist Cheranne & her team with the high-alt KB crew are set to depart aboard this Dhumla when it heads back to the Kongo
Kerbal Space Agency
@KSA_MissionCtrl
🔊🚀video of the initial launch is now up, giving you an idea of just how fast this rocket moved despite its size - those 4 SRBs put out enough thrust for 1.7 TWR! The initial acceleration was important in allowing the main engine to carry on after SRB sep youtube.com/watch?v=Xrac3Z…
Kerbal Space Agency
@KSA_MissionCtrl
moar struts! The mobile launch platform's main deck needed a bit more stability along the drive axis. Ceramic booster plates have been replaced, everything else checks out and it will be parked outside the VAB once again to await its next use later this year
Kerbal Space Agency
@KSA_MissionCtrl
no reports so far of any night time fireballs. The cameras are not in place simply for photographic evidence - they are taking video because we need to see the fireball's track in order to be able to confirm that it is indeed the Viklun stage and not just a chance meteor
Kerbal Space Agency
@KSA_MissionCtrl
all surface locations as well as above caverns have installed full-sky cameras that will be watching each night cycle for any sign of the Viklun stage re-entering over the next 3 days. We expect it to come down around mid-day (local time) on the 27th but could be off by 1 or 2 days
Kerbal Space Agency
@KSA_MissionCtrl
Jeb & Bob have begun launch drills now that the pad is clear again, using an Ascension Mk1 mock-up with the backup capsule. They go through everything from suit-up to ingress to mounting to emergency egress, etc. This week will conclude pre-launch drills
Kerbal Space Agency
@KSA_MissionCtrl
VAB has already moved on, getting ready for our next launches in March. Jeb's Ascension Mk1 is going to start getting its fins on this week while the Progeny Mk7-B upper stage nears completion to await its booster. Capsule RCS installed & awaits integration w/ heat shield and LES
Kerbal Space Agency
@KSA_MissionCtrl
slight difference in how the mission is timed vs. distance traveled is measured. Mission time is from the second probe is deployed to when we lose contact on re-entry. Distance is from the second it switched on & began sending telemetry, to when it hit the top of the atmosphere
Kerbal Space Agency
@KSA_MissionCtrl
here's a look at the full 4d4h7m18s trajectory of Kerbin I, broken up into the five main mission phases. It aerobraked 13 times through Kerbin's upper atmosphere and then (stably) orbited 20 times before falling back, traveling a record total distance of 396,096.3495km
Kerbal Space Agency
@KSA_MissionCtrl
K2-X engine for Specialist Bob's mission in April has been delivered for final inspection, along with static fire testing next month. This is the 2nd of 3 arriving in this first quarter of the year, with 3 more in Q3 that should hold us until the new lifter engine is completed
Kerbal Space Agency
@KSA_MissionCtrl
just under a minute ago FD Lanalye made the final call "Kerbin I telemetry signal has been lost" & sad but satisfied claps filled the room. We hit our re-entry window almost right-on, coming in w/ a Pe of 29.044km (29.151km planned) w/ 6.88% of power & 6.70% cold gas remaining
Kerbal Space Agency
@KSA_MissionCtrl
MLP was finally moved back to the VAB today after extensive inspections were carried out to make sure it suffered the launch alright as designed. Lead Engineer Simon has reported it held up well with only minor issues that need to be looked at before its next use
Kerbal Space Agency
@KSA_MissionCtrl
today our founder and Operations Director @DKerman_KSA accepted official recognition by the Kerbin World First organization for the achievement of placing a payload into stable orbit around Kerbin. CFO Mortimer practically ran off with the award check of 64,000 funds
Kerbal Space Agency
@KSA_MissionCtrl
our best guess therefore is that the spent stage will return to Kerbin around 14:00 UTC on the 27th. This could still be off by as much as a day or more but at least any return is guaranteed to occur at night time which will make spotting it more likely
Kerbal Space Agency
@KSA_MissionCtrl
since then however we've gathered more aerobrake data from Kerbin I and found a correlation. The average drag coefficient from all aerobrakes where it was tumbling (1.130) nearly equals that of the probe's average surface area (1.134). So we have gone & applied the same to Viklun
Kerbal Space Agency
@KSA_MissionCtrl
the scientists at Arekibo have been very generous in letting us try multiple attempts to ping the dead stage but cannot accommodate any more requests without interrupting their own research, so we are left with attempting to estimate when it will finally return to Kerbin
Kerbal Space Agency
@KSA_MissionCtrl
tracking the Viklun stage continues to be a problem. Despite Pe over the terminator it is still too small and not very reflective, nor has it passed directly enough over Arekibo to radar it - at least, attempts based on timings from early drag estimates have had no returns
Kerbal Space Agency
@KSA_MissionCtrl
and one year later - problem solved! Well, partly solved. Ascension team will decide what needs to be done with the attitude control capabilities of the Viklun upper stage as they work through their ongoing launch analysis twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
not sure if anyone actually noticed, but the cameras displayed in the craft image do not match the one displayed in the blueprint. Due to budget issues we used surplus cheaper cameras we had already purchased. They are not even really designed for space flight!
Kerbal Space Agency
@KSA_MissionCtrl
1 of the 8 photos taken Thurs actually had a good look at Kerbin with Mun in the frame too. It has been cleaned up as best as possible but as expected the conditions were not great for the cameras to capture a good quality image. Still, our farthest look at Kerbin yet from 3.8Mm
Kerbal Space Agency
@KSA_MissionCtrl
the 4 SRBs that helped power the Mk2 into space were released w/ just enough burn left to send them flying from the rocket, since the main engine was below them. Due to an early flight throttle issue, rocket wasn't traveling as fast as planned but thankfully this was not an issue
Kerbal Space Agency
@KSA_MissionCtrl
we felt we earned ourselves a photo, so controllers quick pointed one of the cameras towards the horizon and by the time it was in position we managed to just capture the sun setting. We choose to see it as the end of a long journey w/ a new dawn in space exploration now coming!

Kerbal Space Agency
@KSA_MissionCtrl
since we knew there would be no recovery of engineering camera footage, no video was taken just rapid still shots (4fps) that could be beamed down during ascent. Here is the flipover performed by the Viklun stage that had @DKerman_KSA going "No..no..nooo...nononoNONONONOOOOOOOO!"
Kerbal Space Agency
@KSA_MissionCtrl
you can always replay yesterday's launch in the Ops Tracker by visiting this link (ops.kerbalspace.agency) but if you want to do any work with the actual telemetry data it is now available as well: docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
for the same reason, it no longer calculates a trajectory on the Ops Tracker nor shows up in the 3D orbital view. If we manage to get an idea of where its at through visual observation or radar returns from Arekibo we will again display its known trajectory
Kerbal Space Agency
@KSA_MissionCtrl
without power to send telemetry and being too small to track easily the Ascension Mk2 mission distance record accounting was halted when it ran out of power after Kerbin I deployment. It will eventually be surpassed by Kerbin I but currently retains the record of 13,945.799km
Kerbal Space Agency
@KSA_MissionCtrl
the Viklun stage is now completely defunct and will gradually return to Kerbin. Ironically we have unintentionally achieved the goal we had originally intended to achieve on two previous occasions with the Ascension Mk1 of placing a spacecraft into a decaying orbit. Go figure
Kerbal Space Agency
@KSA_MissionCtrl
success! With <2min residual charge in Viklun to relay signal we were contacted by the probe, sent the necessary commands & switched off the antenna since its 500km range wouldn't reach us now once Viklun lost power for good. It will reactivate after perikee pass, AOS in ~15min
Kerbal Space Agency
@KSA_MissionCtrl
we are GO for satellite deployment! Command will be sent this minute to release Kerbin I from the payload truss, which will give it enough of a push that the two craft will separate without any need for additional thrust. Probe will check in 10s later to let us know all is well
Kerbal Space Agency
@KSA_MissionCtrl
acquisition of signal almost right on schedule! Collective sigh of relief passes through controllers. Health checks are underway to ensure no serious damage has been done and the Viklun core can perform the final task of deploying the Kerbin I satellite on this comm pass
Kerbal Space Agency
@KSA_MissionCtrl
Mission Control is fully staffed again as we await AOS (bit.ly/KSATerminology) in a few minutes. The Viklun core cannot hibernate & was operational during both passes through the outer radiation belt. We can only hope this has not caused any serious damage
Kerbal Space Agency
@KSA_MissionCtrl
and now a new record set by the Ascension Mk2: longest mission distance! Trajectory analysis shows it has just surpassed the 9,257.860km record, also from last year's Mk6-II. the Mk2 now has its name on the record, with a + to signify the distance is still increasing
Kerbal Space Agency
@KSA_MissionCtrl
the Ascension Mk2 has set records however! It is now the heaviest rocket ever launched (minus payload) at 17.5t and it is also the tallest rocket ever launched, standing 16m from engine bell to PLF tip. For more records, check out this page on our site kerbalspace.agency/?page_id=72
Kerbal Space Agency
@KSA_MissionCtrl
by now the Viklun stage with its attached payload will have passed through 3,887km apokee, which comes close to but does not break the record set back in July last year by the Progeny Mk6 Block II when it climbed to 4,349.35km ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
post-launch ops wrapping up altho extended cleanup will be needed a few dozen meters north of the runway almost even w/HAB where one SRB impacted. The rest fell harmlessly downrange as planned. The boosters made for a great visual launch even when viewed from the Support Village
Kerbal Space Agency
@KSA_MissionCtrl
we have a better idea of the inner-belt's extent and thankfully the trajectory travels over top of it on the way to apokee & below it on the way to perikee. Even better the apokee is pointing towards the sun, meaning it travels thru the compressed, thinner part of the outer belt
Kerbal Space Agency
@KSA_MissionCtrl
while we have limited knowledge as to the extent of the outer radiation belt, by now the Viklun stage is likely thru 1st of 2 passes with increased radiation. The core itself is not radiation-hardened to save mass but the dual-CPU cross-check at least gives it better tolerance
Kerbal Space Agency
@KSA_MissionCtrl
we completed re-configuring the rocket and prior to LOS @ 17:10:51 UTC we used the last 0.4kg of cold gas in the Viklun tanks to spin up the spacecraft for thermal control. We expect to regain signal @ ~20:25 UTC. Until then, post-launch ops & lots of mission operations meetings!
Kerbal Space Agency
@KSA_MissionCtrl
after deliberation, to salvage the mission we have begun Kerbin I activation. This will allow its batteries to power the Viklun stage. Viklun is designed not to do this until it runs out of its own juice. Kerbin I's probe core & 500km antenna will remain off to preserve power
Kerbal Space Agency
@KSA_MissionCtrl
trajectory analysis has shown we'll lose signal in just over 11 minutes & not regain it for a little over 3hrs. This will completely drain the batteries supplying power to the Vilkun stage and its 1.5Mm antenna, which means we will not regain contact & lose the payload
Kerbal Space Agency
@KSA_MissionCtrl
rocket is through its first aerobrake pass & we have uploaded the telemetry data to the Ops Tracker so you can continue to follow its position in real time. You can use the mouse cursor to find out where it will be at any point along its trajectory ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
RT @DKerman_KSA: I'm about to almost pass out here. Holy kraken. Mad props to the controllers, and I will be the first one to admit that even though we knew the Viklun stage might lose attitude control, the contingencies we had in place were barely adequate. Lessons learned harshly...
Kerbal Space Agency
@KSA_MissionCtrl
a mixture of screams & cheers is still ringing here as we come up just. two. kilometers. short! But while this isn't a stable orbit, it is one that will give us plenty of time to sort through our options, and problems. First problem - 1.5Mm comms range with a 3.9Mm apokee...
Kerbal Space Agency
@KSA_MissionCtrl
OIB underway, almost perikee positive! Everyone in Mission Control, Presider included, are staring up at the monitors pumping their arms & screaming "GO! GO! GO! GO!" We can do nothing else. There is only about 30s of powered flight remaining.
Can we make it?
CAN WE MAKE IT???
Can we make it?
CAN WE MAKE IT???
Kerbal Space Agency
@KSA_MissionCtrl
we've managed to get the rocket pointing prograde but are already thru apokee. With no time for trajectory analysis controllers are just rushing to carefully modify the orbital burn script to begin immediately on upload & we will just have to hope there is enough fuel remaining!!
Kerbal Space Agency
@KSA_MissionCtrl
mad scramble still underway! We've coasted up to space with only 1min until apokee, too soon to take the steps we need to properly plan the orbital insertion burn. Rocket is suffering gimbal lock & not re-orienting prograde. Controllers are desperately sending steering commands
Kerbal Space Agency
@KSA_MissionCtrl
RT @DKerman_KSA: AAAAAAAAAAAAAAHHHHHHHHHHHHH!!!!!!
I'm allowed to scream. I'm just sitting here at my operations overview console watching the *actual* controllers (outwardly) calmly handling the situation. Rocket is still burning for 100km apokee, no matter what

Kerbal Space Agency
@KSA_MissionCtrl
🚨ATTITUDE ALERT!! Gasps & moans filled Mission Control as we watched the Viklun stage slowly tumble almost completely around shortly after SES-1. Thankfully RCS was able to stabilize pointing nearly straight up & 100km target apokee was achieved for SECO-1 with minimal fuel loss
Kerbal Space Agency
@KSA_MissionCtrl
minor roll-shake has developed - so much for hoping the longer Mk2 would be immune. Guidance remains on course however along with pitch. Coming up now on MECO, PLF drop, staging, SES-1 all happening within <1min. Heat build up seen here will quickly dissipate after PLF sep & MECO
Kerbal Space Agency
@KSA_MissionCtrl
nominal attitude on launch but main engine did not throttle properly during SRB boost resulting in a low TWR during initial ascent. Clean SRB sep & good throttle up however. Guidance fins can now actuate further if needed with the SRB decouplers out of the way. Mk2 is supersonic!
Kerbal Space Agency
@KSA_MissionCtrl
main engine ignition was good & with a massive WHOMP the 4 SRBs lit at L-0 to shove the rocket off the MLP almost all by themselves w/over 300kN of thrust. Main engine will throttle up as SRB thrust tapers off, SRBs will detach @ L+32s & main engine will throttle to full
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] nothing left but seconds on the clock! Tune in for live ascent telemetry through OIB: ops.kerbalspace.agency at T-30s we should get the "Go Ascension!", "Go Kerbin I!" calls & live data will load shortly after. Final event sequence:
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] terminal count! Service towers are retracting to leave Ascension on battery power, now switching over to RF comms and monitoring EC load. Viklun flight computers are synchronizing. AFCS now has full control of the launch sequence tho manual hold possible up to L-0
Kerbal Space Agency
@KSA_MissionCtrl
steering constraints for this flight are not very tight since we are not targeting a specific orbit and have enough fuel to salvage a poor ascent. But if you do happen to see any flashing yellow or red telemetry values these are the limit thresholds that are being exceeded
Kerbal Space Agency
@KSA_MissionCtrl
[L-4m] tank pressurization has now begun to add rigidity to the rocket's structure for ascent and more immediately to stand upright on the MLP once the service towers pull away. Winds are out of the west but gust warning system is showing no mountain wave activity
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] Final polls - Range: GO; Flight: GO; Tracking: GO; Payload: GO! WX: GO! Ops Director @DKerman_KSA: Launch permission granted! 🚀GO ASCENSION🚀 FTS power to internal, SRB boltbangs armed, service towers unlocked for retraction, AFCS standing by for terminal count procedures
Kerbal Space Agency
@KSA_MissionCtrl
Presider is back in Mission Control still hoping to perform the final launch count. Astronauts only blocked out the initial launch attempt from their busy schedule so they will have to try and catch the next one. All eyes are on the kerbs at the weather desk now...
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] RSO has closed the range, rocket is ARMED, FTS ACTIVE. Although more planes than normal are in the area (word got around of how easy the rocket will be to see even from afar thx to SRBs) all are sticking to registered flight plans & remain outside the 20km exclusion zone
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] countdown has resumed with a GO from the weather desk confirming surface conditions remain within limits. Hopefully things higher up are better now but the downwards trend was just an observation not a prediction and could have reversed or stalled. If so, day is scrubbed
Kerbal Space Agency
@KSA_MissionCtrl
mission planners have recomputed the ascent with the new launch time & estimated air temps to confirm there is no need for any changes to the current mission plan. If we were actually targeting a specific orbit things would have been a bit more complicated
Kerbal Space Agency
@KSA_MissionCtrl
standby weather balloon has been released - everyone think calming thoughts! Buses have also started running again in case anyone with a viewing ticket was unfortunate enough to miss the deadline in getting to KSC from the Support Village. KSC mess hall remains closed to visitors
Kerbal Space Agency
@KSA_MissionCtrl
rocket is SAFED, FTS is deactivated and countdown has rolled back to L-30m with new L-0 time uploaded to the rocket. Controllers will maintain vigilance while the Presider sets up a temp office in our Admin building and the astronauts, bummed, head out for the day's training
Kerbal Space Agency
@KSA_MissionCtrl
upper-level conditions are more important than usual for this launch because our interstage is the largest yet and its size makes it more vulnerable to wind shear that could literally knock the rocket in two. We are looking to stay well below estimated tolerances
Kerbal Space Agency
@KSA_MissionCtrl
HOLD - we are NO GO from the weather desk, upper-level winds have not died down enough to meet our tight constraints but they are trending downwards since last measurement. Decision is to wait it out & try again, aiming for the end of the daylight launch window @ 16:45 UTC
Kerbal Space Agency
@KSA_MissionCtrl
the astronauts, recently woken up since they were all training all day yesterday, have crowded into Mission Control to say hello to the Presider and watch as the final minutes tick down. Controllers are glued to their monitors, checking readouts in prep for final general polls
Kerbal Space Agency
@KSA_MissionCtrl
[L-13m] small tanker truck left hooked up to the service towers has been remotely commanded to begin onload of nitrogen gas for tank pressurization. This ensures any tank rupture and resulting explosion poses no harm to ground crew
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] RSO has confirmed pad/waters/airspace are clear, range is now closed & rocket is ARMED. Flight Termination System is ACTIVE. Visitors at KSC must remain in their designated areas. Security is doing a final sweep outside to ensure everyone has hearing protection
Kerbal Space Agency
@KSA_MissionCtrl
Presider has arrived. His first question was where the big red LAUNCH button was so he could be the one to push it. FD Lanalye had to explain that's not quite how it works, and he was visibly disappointed but she did say he could call out the final 10s countdown so he's happy now
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] Kat says we are GO for final countdown procedures! Surface weather has continued to improve, thankfully in this case forecasts are still not that great. Presider is on his way to Mission Control & all consoles are being reset for launch, switching over to the live rocket
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h] all buses have ceased to prepare for the Presider to be transported over to KSC while FD Lanalye works her teams through a mission rehearsal to ensure all consoles are properly setup and all controllers know their roles. Ground crew is conducting final pad evacuation
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h35m] high-altitude weather balloon has started its ascent to 25km so that by L-5min polls the kerbs at the weather desk (now led by KWS meteorologist Katgan) have a better idea if conditions in the upper atmosphere have improved or not since the last check earlier today
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h45m] preflight is complete and rocket is healthy, ready to go! Ground crews moving back in to secure the MLP and perform final pad checks & prep. Range Safety Officer continues to assess airspace and waters around KSC & prepares to close down the launch corridor
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h30m] no issues reported, preflight proceeding smoothly into checks of the K2-X, Viklun and SRB-XL engines that will power the flight to space. For safety all crews are evacuating the pad area - rocket+MLP is too big to even allow a quick-response team in the bunker anymore

buses have begun running from the Support Village to deliver ticketed visitors to the viewing areas. Loading is outside the parking garage & as advised during ticket purchase an extra security check will be in place before entering the KSC campus. Buses stop at L-1hr!!
Kerbal Space Agency
@KSA_MissionCtrl
the Viklun computer core is the first to have dual CPUs to cross-check each other for errors or take over from the other if one completely fails. This is all transparent to the AFCS though, the changes for multiple CPUs refers to discrete cores: in this case ascent & payload
Kerbal Space Agency
@KSA_MissionCtrl
preflight is underway as launch controllers begin to wake up the Viklun flight computer, which will guide the rocket up to orbit. You can check out the flight code and some minor changes to the boot script to support multiple ship CPUs here at bit.ly/AFCS_ChangeLog
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h15m] briefing broke up with hand shakes and quick hugs, lots of "have a safe launch!" as the ground crew departed for the pad & controllers went to their stations. Consoles will serve double duty with launch/mission controllers taking turns as needed during the orbital phase
Kerbal Space Agency
@KSA_MissionCtrl
here is the ascent profile & mission overview. Times are not given for events beyond SECO-1 because that all depends upon how the ascent goes. If orbital insertion is as planned then the mission will progress as shown. If not - PANIC!
No not really, there will just be a new plan
No not really, there will just be a new plan
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h50m] excitement is aiding everyone in getting up early to be present for final mission briefing by Flight Director Lanalye, although it almost had to be pushed back due to overcrowding at the koffee machines. Mess hall stepped up tho & all controllers are fueling up
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h30m] weather balloon released earlier shows upper-level conditions are more disturbed than we'd like but not enough to call off launch attempt. Surface forecast has also improved to 80% so we will proceed with prelaunch - expect updates at these major milestones
Kerbal Space Agency
@KSA_MissionCtrl
even if you consider the time since it was re-designed and re-dubbed the Mk2, we're still talking about back in April of 2019. It's been a long road but it always ends at the launch pad 🙂
Kerbal Space Agency
@KSA_MissionCtrl
we just compiled the initial tweet collection for the Ascension Mk2 Flight 1 mission timeline and... woah. We've just thought about the fact that this rocket has been under development & waiting to launch since it was first announced as the Mk1 Block II back on March of 2018!
Kerbal Space Agency
@KSA_MissionCtrl
all launch readiness reports have been reviewed & approved by Ops Dir @DKerman_KSA. We are 🚀GO FOR LAUNCH!🚀 Weather forecast for tomorrow is 65% favorable, which is on the low end but still possible. Launch prep Go/No Go will be made @ 10:03 UTC tomorrow. Who plans to watch?
Kerbal Space Agency
@KSA_MissionCtrl
the probe's RCS thrusters are laid out so that while the rocket is powered by the Viklun engine, which has no gimbal, the pitch control can use up to 5 thrusters to keep the rocket on course. In theory. This is an untested mission aspect & why we have a large error margin in fuel
Kerbal Space Agency
@KSA_MissionCtrl
Kerbin I has completed checkouts, is now powered down; main fuel valves closed & all electrical/comm systems switched off. Crossfeed valves will remain open to allow use of its RCS ports during ascent after PLF separation. It will be re-activated prior to orbital deployment
Kerbal Space Agency
@KSA_MissionCtrl
rocket has been topped off, both ascent stages, with 9t of liquid propellants. These can still be carried by a single one of our large tanker trucks. After wet dress rehearsal rocket will stay fueled to allow for a condensed countdown early tomorrow
Kerbal Space Agency
@KSA_MissionCtrl
sea cable has begun to be laid to the west while ground cable has started to dig in to the east, looking to link up fiber between the Kongo & Kravass. Arekibo is almost equidistant but with the exiled kerbs on that landmass, decision was the least amount of land cable the better
Kerbal Space Agency
@KSA_MissionCtrl
Flight Director Lanalye & Lead Engineer Simon are both saying "so far so good" in regards to pad checkouts of the rocket systems and ground systems. Their final reports will be submitted tomorrow after WDR for launch readiness review. hype video! 🚀 @KerbalSpaceP #KSPloring
Kerbal Space Agency
@KSA_MissionCtrl
Jeb & Bob have been spending more & more time in the capsule lately as their mission nears, working through the standard script of procedures & emergency events based on previous flights. By next month FD Lanalye will be able to get creative again in her attempts to "kill" them
Kerbal Space Agency
@KSA_MissionCtrl
the Presider got a tour of the KSC campus today to check out all the new stuff since his last visit. He was especially pleased to witness the SRB static fire and he stood so close to the Ascension Mk2 his neck got sore staring up at it. He's excited for the launch!
Kerbal Space Agency
@KSA_MissionCtrl
full thrust burn of 37s was completed with all the explosions coming out the proper direction. With a dual-segment the join in the casing was highlighted as a potential fail point of the design. A great first step for the new booster! It will be returned to the VAB for inspection
Kerbal Space Agency
@KSA_MissionCtrl
farthest to the left is the Kongo River Research Station 500km antenna, the only one w/o ground link to KSC. So we cannot relay commands through there but it can still receive & store telemetry data in case anything happens over that region before Kravass can reacquire signal
Kerbal Space Agency
@KSA_MissionCtrl
upcoming mission will be the 1st to make use of all operational bit.ly/GrndStns & the past 2wks have been spent ensuring all dishes are calibrated & relays are in working order. Only DSN North/South are not shown as they don't go into service until later this year
Kerbal Space Agency
@KSA_MissionCtrl
because this is the first time we've used all 3 GSE towers, rocket has been rolled out well in advance of launch to allow us to troubleshoot any issues, as well as run full system checks on the Viklun orbital stage and Kerbin I probe through Launch/Mission Control
Kerbal Space Agency
@KSA_MissionCtrl
service tower hookups are completed, for the first time the entirety of the GSE is in use. Lower two booms provide fuel, walkway itself is not used but the resource connectors below carry power to the Viklun & Kerbin I CPU cores. Struts will be removed after engine clamp install
Kerbal Space Agency
@KSA_MissionCtrl
Mobile Launch Platform is rolling! Exiting the VAB it will slowly make its way 655m to the launch pad, traveling no faster than 3m/s - which is actually 2x quicker than the Mk1 carry vehicle thanks to its extra power & wider base for better stability at "high speed"
Kerbal Space Agency
@KSA_MissionCtrl
working through the weekend, VAB crews have completed an exhaustive checklist to make sure the Ascension Mk2 is fully assembled and ready for roll out tomorrow. With so much riding on this rocket, Lead Engineer Simon says he can't shake that phantom feeling "what did we forget?"
Kerbal Space Agency
@KSA_MissionCtrl
last year Presider Theonard was visiting to watch Specialist Bob become the first kerbal in space, but unfortunately the Monolith had other plans and his busy schedule meant he could not stay for the second attempt with Spc Bill. Full mission report: kerbalspace.agency/?p=9395
Kerbal Space Agency
@KSA_MissionCtrl
the Presider's flotilla has arrived and moored outside the Support Village. As with his visit last year, we were unable to announce his attendance ahead of time and his presence is why we are unable to have general admission at KSC. We hope he gets to enjoy a launch this time!
Kerbal Space Agency
@KSA_MissionCtrl
3-4 days depending on how things progress. There is enough power to hibernate for 5 days if needed. We'll want it up there as long as possible to do as much as it can
Kerbal Space Agency
@KSA_MissionCtrl
we're keeping this mission directly under the Ascension program since it will not be operating long on its own. Future missions that have goals beyond being a test object will come with more unique patches
Kerbal Space Agency
@KSA_MissionCtrl
everything is continuing on schedule for roll out of the Ascension Mk2 to occur at the start of next week ahead of launch. Get hype!! Also get information on what else went down this past week via our Ops Summary: kerbalspace.agency/?p=10404
Kerbal Space Agency
@KSA_MissionCtrl
today the rocket was fully stacked - here is the orbital stage being lowered onto the interstage support shroud. It was then secured to the lifter and the other shroud half was installed. The payload topped it off & the rest of the day is removing worker access scaffolding
Kerbal Space Agency
@KSA_MissionCtrl
tickets for the launch have sold out and there will be NO general admission for the non-ticketed areas of KSC. We apologize for the inconvenience but have setup general-admission viewing areas at the Support Village. We promise the views are just as good!
Kerbal Space Agency
@KSA_MissionCtrl
the Mobile Launch Platform was moved today - VAB doors were opened to allow the MLP to position itself and prepare to receive the lift stage, which will be strutted down after it is lowered onto the booster plates. The Viklun orbital stage and payload will be stacked tomorrow
Kerbal Space Agency
@KSA_MissionCtrl
with Jeb & Bob carrying out recovery drills, launch drills and capsule sim runs Val & Bill have time in their relatively light CapCom workload to take on some additional training in the centrifuge. Val says she hates just sitting inside & wants to practice actions under load too
Kerbal Space Agency
@KSA_MissionCtrl
all the guidance fins have been mounted and the lifter is vertical. One segment of the interstage shroud is being installed to support the Viklun stage at mounting later this week while allowing the engine to be secured to the base. Progeny Mk7-B parts have arrived as well
Kerbal Space Agency
@KSA_MissionCtrl
this is our 3rd attempt because the Ascension Mk1 was actually designed with orbit in mind but failed to have the control authority or delta-v to make even a highly-eccentric decaying orbit after 2 attempts in mid 2018. More details: kerbalspace.agency/?p=8387
Kerbal Space Agency
@KSA_MissionCtrl
rocket assembly is proceeding on schedule, mission planning has been reviewed & approved - launch date for our 3rd orbital attempt has been set! Get ready to witness history on 2/20 with lift off set for 14:33 UTC 🚀! Full details: ops.kerbalspace.agency #KSPloring @KerbalSpaceP
Kerbal Space Agency
@KSA_MissionCtrl
Ascension program planners are still working the updated drag and flight dynamics results from the Mk1 flight into the Mk2 ascent trajectory to make sure we still end up in an orbit so expect a launch date next week. What about this week? Catch up: kerbalspace.agency/?p=10393
Kerbal Space Agency
@KSA_MissionCtrl
technicians do some final checks before the VAB empties for the weekend. Boosters are on, fin installation will continue through next week, payload is checked out & encapsulated. In the back is the fuel tank that was ordered late last month for Jeb's mission
Kerbal Space Agency
@KSA_MissionCtrl
eventually we will have satellites in orbit for years at a time, which will require operations by separate teams. Until now the launch control team also handled mission control since the missions don't overlap the next launch. Moving forward the teams will become more specialized
Kerbal Space Agency
@KSA_MissionCtrl
Flight Director Lanalye is excited to soon put into action the mission operations control team! They have been training for months now and Kerbin I will be the first ongoing mission after launch. Tho it will only last a few days, still good to finally get MOC team on console
Kerbal Space Agency
@KSA_MissionCtrl
careful analysis has revealed the Mk1 lifter fins are indeed capable of flying the rocket on an orbital trajectory. You can read for yourself or just take our word for it: kerbalspace.agency/?p=10380 Regardless - Ascension Mk2 launch date coming soon!!
Kerbal Space Agency
@KSA_MissionCtrl
the development of the new lifter engine has been confirmed to be behind schedule (no other details have yet been released) so to fill the gap we have placed the order for 3 more K2-X engines that will start to arrive in July
Kerbal Space Agency
@KSA_MissionCtrl
at least some good news to come out of today: the newest K2-X engine was hooked up to the test stand & underwent successful static fire. It will be moved back to the VAB tomorrow to begin integration w/ flight hardware for March's mission. Horizontal stand awaits Boosterton II
Kerbal Space Agency
@KSA_MissionCtrl
Jeb & Bob have boarded MSV Aldeny with the capsule to sail offshore and begin working with recovery crews on capsule splashdown drills, from normal recovery to emergency operations. A float collar at the base inflates to keep it buoyant and upright for easy extraction
Kerbal Space Agency
@KSA_MissionCtrl
monthly financial report has been released by CFO Mortimer - lightning towers, centrifuge, pad repairs - lots of large infrastructure expenses this month. We expect to burn money the first half of this year but not as much as January (we hope) docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
yes, we feel the pressure waiting for the Mk1 flight report to be released but you can't rush these things. Hopefully next week we will know if the Mk2 mission is approved! Until then, read more about what happened this past week in our Ops Summary: kerbalspace.agency/?p=10366
Kerbal Space Agency
@KSA_MissionCtrl
after a week of multiple high-G runs in the centrifuge using the latest suit, seat and strap adjustments (based on data from Murstap's tests) both Bob and Jeb report to be feeling much less fatigued and have found the stresses to be more tolerable under slightly higher and longer exposure
Kerbal Space Agency
@KSA_MissionCtrl
launch pad remains in good repair, reports the team assigned by Lead Engineer Simon, who has just signed off on the review. This is great news and means no further delays stand in the way of the next launch
Kerbal Space Agency
@KSA_MissionCtrl
here is a new render of the Mk2 with the payload fairings enclosing Kerbin I at the top (instead of the Mk1 capsule) along with the technical specifications of the rocket that we are using to plot its ascent to orbit in Launch Vehicle Designer from bit.ly/KSP_TOT
Kerbal Space Agency
@KSA_MissionCtrl
final design work for the Mk1-B capsule remains ongoing, with one of the recent decisions being not to attempt to integrate the heat shield into the capsule bottom, which would make re-use more complicated and also not allow for varying levels of ablator to be used as easily
Kerbal Space Agency
@KSA_MissionCtrl
the lightning towers of the launch pad seem to prop up a gibbous Mun over the service structures. Empty once again, hopefully the next rocket to be received by the pad will be the Ascension Mk2 atop the Mobile Launch Platform!
Kerbal Space Agency
@KSA_MissionCtrl
RT @Tmccreight25: A spacewalk is definitely an interesting idea, but i don't like the thought of a Kerbal exiting their capsule whilst on a ballistic trajectory... gives me horrible visions of them being unable to return to the spacecraft and seal the hatch before reentry cooks them alive...
Kerbal Space Agency
@KSA_MissionCtrl
ever since we demonstrated it was possible to open the Mk1 capsule hatch in space then close & secure it again for safe re-entry on an unkerbed flight rumors have persisted about a spacewalk from Jeb or Bob. Official response: As of right now we have NO such plans
Kerbal Space Agency
@KSA_MissionCtrl
we are also keeping open the possibility that the 3rd K2-X engine would be used for a second orbital Mk2 flight, although such a mission would be under planning long enough that a new order of K2-X or the new lifter engine would likely be ready by then
Kerbal Space Agency
@KSA_MissionCtrl
new fuel tanks & other parts for 3 add'l Ascension Mk1 missions will be ordered over next few months to cover the flights of Jeb & Bob as well as an unkerbed test flight. This will use up all remaining lift engines by April & unsure at this time if the new engine will be ready
Kerbal Space Agency
@KSA_MissionCtrl
we've received the 1st of the three K2-X engines ordered back in August 2019 which will be test fired next week and if all is well be set aside for use with Cpt Jeb's mission in early March. The following two engines will arrive in February and March
Kerbal Space Agency
@KSA_MissionCtrl
Head of R&D Wernher von Kerman has his team (and his new interns) working hard on new ideas for science instruments that can be carried on probes large enough to be launched by a 1.25m rocket like Ascension currently fields
Kerbal Space Agency
@KSA_MissionCtrl
the Ascension Mk2 is center stage in the VAB for final assembly of the lift stage, which will start strapping on boosters and final checkouts of the Kerbin I probe before fairing encapsulation. The Viklun stage has been tested, ready & waiting for months now!
Kerbal Space Agency
@KSA_MissionCtrl
since capsule re-use is something we are monitoring closely, the unused backup capsule will become primary for the next two flights. This will keep re-use of the unkerbed capsule well ahead of any ones we use for kerbed missions so any hint or actual failure is spotted in advance
Kerbal Space Agency
@KSA_MissionCtrl
we are pleased to hear Lead Engineer Simon report that the capsule from the pad abort of Jeb's mission has been re-certified for flight. It required only minimal repairs from the landing on hard ground but was nonetheless put through extensive testing these last few months
Kerbal Space Agency
@KSA_MissionCtrl
great to get a space mission off the ground this month! A bit of Mk1 preliminary analysis along with additional details for other major events this past week await your attention in our Ops Summary: kerbalspace.agency/?p=10336 have a relaxing weekend, everyone
Kerbal Space Agency
@KSA_MissionCtrl
here's a look at the rough ride the rocket endured passing the transonic regime (+1 Mach), which lasted to some degree all the way through to MECO. This "roll shake" has been experienced to various extents in past flights and is still something we are trying to understand
Kerbal Space Agency
@KSA_MissionCtrl
great question. We were wondering if anyone would ask why no parallel runways but this is another reason besides winds changing a lot near the water. Aircraft can still take off/land on Rwy 03/21 even during launch operations
Kerbal Space Agency
@KSA_MissionCtrl
KSC is about to get a lot bigger! Here is the final plan for the commercial airport expansion project that will begin construction this month and finish up by August. Work on the new railway tunnel from Umbarg continues on schedule to be complete in early March
Kerbal Space Agency
@KSA_MissionCtrl
Lead Engineer Simon is having his teams perform yet another full and extensive check of the launch pad and ground service equipment now that it's all been actually used to make double sure the repairs are holding before any missions in Feb are approved for flight
Kerbal Space Agency
@KSA_MissionCtrl
as we said, lots to analyze from yesterday's flight but if you want to go ahead and draw your own conclusions on anything, the telemetry data up until plasma blackout is now available: docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
chances are tho the final report for this flight won't be out until early Feb since not only does a review need to be made of the Mk1's general performance & comparison to LVD planning but also as both would apply to the potential follow-up flight of the Mk2
Kerbal Space Agency
@KSA_MissionCtrl
airship is on its way back to Sheltered Rock after locating and recovering the RTG casing - ✨🎉 KERZZAH!! 🎊✨ we should hear by next month how it endured its ballistic return from space. Perhaps sooner we'll also get a full report on the performance of this flight
Kerbal Space Agency
@KSA_MissionCtrl
post-launch operations are wrapping up while we await word from the airship, which is just now nearing the search area. The beacon within the RTG casing has 12 hours of battery power but they need to be within 2km to pick it up. The hunt begins!
Kerbal Space Agency
@KSA_MissionCtrl
we have failed to regain contact with the payload after plasma blackout, as expected. Ground controllers are already using the last-received data to give our airship charter a smaller box of coordinates to search for the impacted RTG, the only part that will be recovered
Kerbal Space Agency
@KSA_MissionCtrl
Ascension Mk2 will continue its ascent burn with the 2nd stage engine after 45km and aim for an apokee of ~100km for orbital insertion
Kerbal Space Agency
@KSA_MissionCtrl
less than a minute to atmospheric re-entry. At apokee after fuel tank purge the RTG, probe core, batteries & antenna were separated from the lift stage as planned so its large drag doesn't slow things down further. The antenna will most likely burn off during re-entry
Kerbal Space Agency
@KSA_MissionCtrl
already only 20s from apokee, updated plot of the rocket's trajectory shows it on a shallower path, despite final apokee almost spot-on with LVD planning, with re-entry further downrange in a lower area, which is not ideal since it gives RTG more time to slow down
Kerbal Space Agency
@KSA_MissionCtrl
MECO @ 45km along w/ separation of the payload fairings. Rocket managed to orient and hold prograde even as the atmosphere continues to rapidly thin. Apokee was just over 80km at MECO but will degrade ever so slightly as rocket coasts out of atmo & still encounters drag
Kerbal Space Agency
@KSA_MissionCtrl
past Mach 1.3 rocket picked up roll shake that has eased but continues thru 2nd min of flight. Rocket wobble seems to be having an effect on pitch control. Significant heating has built up at the nose but this was expected & should ease after passing through 40km in a few seconds
Kerbal Space Agency
@KSA_MissionCtrl
some serious steering corrections early even before launch likely from gusting winds but rocket is now stable, through Max Q and has achieved supersonic velocity. Throttle program running as programmed to keep speed in check. Course is back on track & pitch nominal
Kerbal Space Agency
@KSA_MissionCtrl
engine start good, launch thrust nominal - we have LIFT OFF!! The 11th Ascension Mk1 begins its ascent to pave the way to orbit for the Ascension Mk2. Throttle program will kick in once it clears the tower and begins to increase its pitch over downrange
Kerbal Space Agency
@KSA_MissionCtrl
[L-1m] make sure to tune in to the Ops Tracker for live ascent telemetry! ops.kerbalspace.agency it will come up after final L-30s polls if we are still GO. Past that, these are the final steps leading up to launch
Kerbal Space Agency
@KSA_MissionCtrl
[L-2m] we are now in the terminal count where the Automated Flight Control System takes full control to perform the final sequence leading up to launch. Rocket is switched over to internal power & RF comms with the detachment of the service arm. Final checks underway
Kerbal Space Agency
@KSA_MissionCtrl
[L-3m] tank pressurization has begun to strengthen it & allow the rocket to stand rigid atop the launch clamp after the service structure has been swung away and the rocket is at the mercy of surface winds, which have just started gusting
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] upper-level wind conditions are green!! Final polls passed - Range: GO; Flight: GO; Tracking: GO; Payload: GO! Ops Director @DKerman_KSA: Launch permission granted! 🚀GO ASCENSION🚀 FTS power internal, service tower boom unlocked for retraction, AFCS rdy for terminal count
Kerbal Space Agency
@KSA_MissionCtrl
this flight is operating under extremely tight tolerances for various aspects. If you see any yellow or red flashing telemetry values during the ascent, these are the constraints the rocket will be operating under. Values are trigger thresholds
Kerbal Space Agency
@KSA_MissionCtrl
[L-13m] nitrogen gas is being onloaded from a small tanker left hooked to the service towers, which is used to keep the fuel tanks pressurized. This is done late in the countdown while the pad is permanently cleared of all crew to prevent any injury in the event of a tank rupture
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] Range Safety Officer has closed the range, pad crews have cleared out. Flight Termination System is ACTIVE, engine is ARMED. All kerbs must remain inside designated spectator areas & remember hearing protection while outdoors for launch is REQUIRED
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] 🎵 It's the final countdown... 🎶 we are still unsure of upper-atmospheric conditions but surface conditions are forecast to remain green for launch the remainder of the day cycle, so in the event of a scrub due to upper-level winds we will have the chance to wait it out
Kerbal Space Agency
@KSA_MissionCtrl
[L-45m] pad is locked down, crews standing by in case any new issues pop up in the launch rehearsal that is about to get underway. Crowds are starting to gather outside as more kerbs are bused over from the Support Village. Astronaut Complex mess hall closes in 20min!
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h20m] off on the water our small utility boat has released another weather balloon, which will reach the upper-atmosphere just prior to L-5min polls to give us an update on upper-level wind conditions. With tightened constraints, they need to be calmer than usual
Kerbal Space Agency
@KSA_MissionCtrl
to be clear, boats, aircraft and airship all exist in the area, but they are all staying outside our exclusion zone and they are all operating on registered route plans. A "bogey" would be any object of unknown nature, not just on track towards KSC
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h30m] rocket is healthy & prepped for flight! Issues board remains clear, now to ensure airspace & waters around KSC will remain clear for launch as well. SkyWatch is currently tracking no bogeys on course for KSC but will remain vigilant while ground crews close out the pad
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h55m] preliminary pre-flight has been completed without issue, leaving only the engine & ignition systems left to look at. For crew safety the pad is being evacuated ahead of these final checks
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h40m] tanking has wrapped up on schedule, with crews already getting the truck unhooked and controllers continuing with their preflight operations while keeping a close eye on tank levels to ensure there are no minor leaks in the fuel system
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h55m] rocket has been initialized & configured for fueling. Crews on the pad have been given the GO by controllers to begin onloading 7t of liquid propellants, then clearing out to a safe distance for the duration of tanking operations. Check out the new pad lights!
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h10m] launch controllers are moving into preflight operations as the ground crews on the launch pad receive the tanker truck. Operations code will soon be onloaded to the rocket's flight controller, which can be reviewed here bit.ly/AFCS_ChangeLog
Kerbal Space Agency
@KSA_MissionCtrl
more details on the Mk2 orbital path colors from our Ops Director earlier this month: twitter.com/DKerman_KSA/st…
Kerbal Space Agency
@KSA_MissionCtrl
the slower ascent also means the final trajectory is reasonable - at full throttle this ascent would send the Mk1 halfway to Mun!! This would place it out of radio range, unsure of its impact location. Instead it will fall around Sheltered Rock to perform another RTG impact test
Kerbal Space Agency
@KSA_MissionCtrl
in addition to flying the same pitch profile, the Mk1 also has to throttle to match velocity of the slower & heavier Mk2. If it didn't do this, the faster speed would increase airflow and thus control authority, making it harder to determine if Mk2 could then follow suit
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h40m] all of Flight Director Lanalye's launch team A are assembled & ready, now going through the final pre-flight briefing. Mission profile will simulate a Mk2 ascent, tasking the Mk1 to fly the same trajectory that has already been simulated to place a Mk2 into orbit
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h10m] weather balloon that was released earlier today has returned data that meteorologists have used in their updated forecast which predicts 90% favorable launch conditions at the surface. That is a GO for launch controllers to get on console & begin prep for prelaunch ops

ongoing mystery goo studies have found the larger colonies that seem to allow for higher-level functions are much more successful in locating new deposits of Kuudite, allowing for our future demand of RTGs to be met once they are certified for space use
Kerbal Space Agency
@KSA_MissionCtrl
weather conditions continue to fail to meet launch commit criteria, which means we will stand down today and make another attempt tomorrow, targeting lift off @ 18:40 UTC which means we'll have a decision to begin launch countdown @ 15:30 UTC
Kerbal Space Agency
@KSA_MissionCtrl
launch has been delayed 6hrs due to upper-level winds & the threat of a low-pressure system encroaching from out at sea carrying thick cloud cover over the KSC. We will launch another balloon to determine if conditions have improved to begin countdown @ 20:27 UTC
Kerbal Space Agency
@KSA_MissionCtrl
our new tighter launch commit criteria extends to launch procedures as well, as in we will not even start them w/o good indication of acceptable weather later in the day. Balloon is already on its way up to give meteorologists data to determine if countdown will begin @ 14:27 UTC

Ops Director @DKerman_KSA has received & reviewed all launch readiness reports. Despite new stricter launch commit criteria for all aspects of our rocket programs, the teams have stepped up and all is ready for launch attempt tomorrow 🚀! Countdown set to begin @ 14:27 UTC
Kerbal Space Agency
@KSA_MissionCtrl
SkyWatch team has confirmed our ground-based radar system that provides 360° coverage of KSC airspace along with coverage of the waters east of KSC is functioning nominally to ensure no sea or air-based incursions present a possible hazard to launch procedures

@KSA_MissionCtrl
Flight Director Lanalye has been drilling her A team hard since the start of the month to get back to used to working with the Ascension after two months of Progenitor operations. The B team has already been working since last month to prep for operations with the Progeny Mk7-B
Kerbal Space Agency
@KSA_MissionCtrl
good reports in from down-range tracking stations at Sheltered Rock and Ockr, which don't actually actively track the spacecraft but allow for relay of telemetry that allows us to continue to monitor its progress during flight once it flies over the horizon from KSC
Kerbal Space Agency
@KSA_MissionCtrl
the Ascension Mk1 began its trip to the launch pad a short while ago to be mounted, seen here rolling out of the shadow of the VAB as we approach 2nd sunset. By the time the sun rises again it will be vertical and undergoing final launch readiness checks
Kerbal Space Agency
@KSA_MissionCtrl
in the past we've used "scrub" and "delay" a bit interchangeably to describe the withholding of a planned launch. Moving forward they will have specific uses. "Scrub" will define a launch in process that was halted during countdown. "Delay" will occur before countdown starts
Kerbal Space Agency
@KSA_MissionCtrl
we're starting to pick up speed again, getting set for our first rocket launch of 2020 next week. Make sure you didn't miss anything else that was announced & learn more about what happened this past week by checking our Ops Summary: kerbalspace.agency/?p=10289
Kerbal Space Agency
@KSA_MissionCtrl
Jeb & Bob have begun taking runs in the centrifuge that will simulate re-entry forces similar to what Cdr val endured on her flight, which flew the highest with a kerbal aboard
Kerbal Space Agency
@KSA_MissionCtrl
Lead Engineer Simon reports the launch pad is ready for action, Mk1 final integration is proceeding well in the VAB so we have gone and set our first launch date for 2020! Get ready for the Ascension Mk1 to blast off next week, 1/21 @ 18:37 UTC 🚀! ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
with the Ascension Mk1 lift stage back in the VAB the encapsulated payload can now be integrated, beginning with a vertical stack to ensure load-bearing parts of the payload truss and fuel tank are properly manufactured before lying horizontal for final close-out checks
Kerbal Space Agency
@KSA_MissionCtrl
crew training was planned and begun last month but has now kicked into high gear for the next kerbed Ascension mission (TBD NET Mar). Captain Jeb will once again be primary crew with Specialist Bob as his backup. Spc Bill will be primary on CapCom with Commander Val as his backup
Kerbal Space Agency
@KSA_MissionCtrl
Ascension Mk1 is being rolled back to the VAB after Wet Dress Rehearsals were carried out with no major complications. A good sign, but further examination of the various pad ground service systems is still needed before we can ensure it is ready for launch capability again
Kerbal Space Agency
@KSA_MissionCtrl
what are we hoping to achieve in 2020? Last week we shared details on Extremis goals and now we have information for the rest of our programs in this report: kerbalspace.agency/?p=10258 what are you most looking forward to from us in 2020?
Kerbal Space Agency
@KSA_MissionCtrl
to ensure the pad repairs are good to go, the next Ascension Mk1 has been rolled out today sans payload to hook up to the service tower for testing and a wet dress rehearsal. Lead Engineer Simon says results will be in next week on pad readiness
Kerbal Space Agency
@KSA_MissionCtrl
up until now the crew service tower has also acted as a lightning rod but the Ascension Mk2 can rise taller so rods have been installed around the pad to protect it from any hazardous weather. Yes, they are also sunk several meters into the ground & will stop an aircraft
Kerbal Space Agency
@KSA_MissionCtrl
a new photo has been captured of the KSC to update our online banner images - also we made another significant upgrade after the completion of pad repairs over the break. Look closely in front of the Support Village for the engine test stands & the VAB for the MLP
Kerbal Space Agency
@KSA_MissionCtrl
behind the payload workers are busy getting the old static fins off the future Mk2 tank to be replaced with actuating fins, which will also be tested on the next Mk1, which is off-image to the right at "center stage" for final tank/engine/fin integration checks
Kerbal Space Agency
@KSA_MissionCtrl
Lead Engineer Simon reports work in the VAB is ramping up well coming back from the break, with final checks being performed on the next Ascension Mk1 payload before it is encapsulated in the first set of 1.25m payload fairings set to be flown hopefully later this month
Kerbal Space Agency
@KSA_MissionCtrl
CFO Mortimer has compiled his report for December as well as all of 2019 to show that we actually managed to pull off a small profit this past year. Kerzzah! Still quite a ways from net gain but a promising step towards commercial success docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
an early decision that was nearly unanimous was to retask the Extremis program to include *all* missions sent to other bodies, not just the original fly-by attempts currently being planned. This could make it relevant as early as this year with a Mun/Minmus mission
Kerbal Space Agency
@KSA_MissionCtrl
over the operational break the centrifuge was completed, adjacent to our HQ in Umbarg. It's been going through test runs with Greggery and this week our crew should all get a chance to pull some major extended Gs and see what they are really capable of
Kerbal Space Agency
@KSA_MissionCtrl
KSA 2020 ops are kicking off this week with meetings! Lots and lots of meetings as the various programs decide on their goals for the coming year, which we will report on over the course of this week. Admin makes final decisions but all team members contribute
Kerbal Space Agency
@KSA_MissionCtrl
welcome to 2020!! 🎉🥂 Kerbs are eager to get back to work next week, so much so that Operations Director @DKerman_KSA revoked access privileges to force some to take a vacation. We're not naming names but their initials start with Wernher von Kerman
Kerbal Space Agency
@KSA_MissionCtrl
bye bye 2019! KSA operations for the year have concluded. We will continue to note significant past events on weekends, ATN weekly updates & asteroid bulletins, or any other significant events. Regular ops will resume 1/6/202️⃣0️⃣! Final ops summary: kerbalspace.agency/?p=10213
Kerbal Space Agency
@KSA_MissionCtrl
check it out - 2019 was the first full calendar year that saw continuous operations! We did take a few hits this year that reduced our operational capacity but KSC was not shut down for any extended period of time. Here's looking to a stronger 2020!
Kerbal Space Agency
@KSA_MissionCtrl
rocket launches were up from last year, which only had 11, and we put 2 kerbals into space! That lineup could increase to as many as 6+ rockets by the end of next year with continued development of the Progeny Mk7 along with debut of the Ascension Mk2 & Mk3
Kerbal Space Agency
@KSA_MissionCtrl
a tumultuous year for our crew - a death, severe injury, severe anxiety, almost getting blown up... Val & Bill had it the best with successful space missions. Hopefully Jeb & Bob will get to pin some new ribbons next year. Will our crew grow again? Possibly
Kerbal Space Agency
@KSA_MissionCtrl
VAB is getting everything organized to pick up with Ascension assembly next year, launch pad repairs are on schedule to wrap up next week, Launch Control is prepping for system upgrades over the operations break... we're almost ready to bid farewell to 2019!
Kerbal Space Agency
@KSA_MissionCtrl
KerBalloon program was unable to secure any nearby missions & is packing it up for the year. Kongo high-alt crew are happy to finally be heading home. Year in review shows how we are still sticking mainly to our hemisphere, but satellites in 2020 could change that
Kerbal Space Agency
@KSA_MissionCtrl
heading into the weekend with a good report from Lead Engineer Simon that the rocket has passed load checks and will undergo final closeouts at the start of next week. That and more that went down this past week in our Ops Summary: kerbalspace.agency/?p=10164
Kerbal Space Agency
@KSA_MissionCtrl
ATN has officially removed bit.ly/Zosimus from its catalog. No sign of the asteroid has been found and it likely broke apart on its last pass through the atmosphere earlier this week. Data from its encounters with our atmosphere will help improve aerobrake models
Kerbal Space Agency
@KSA_MissionCtrl
the final Progeny Mk6-I rocket of 2019 was stacked in the VAB today for checks on its load bearing elements, clearing the way for Ascension assembly to take "center stage" next year. In the back are the core stages for the Ascension Mk1 and Mk2 & the Viklun orbital stage
Kerbal Space Agency
@KSA_MissionCtrl
launch pad resurfacing was completed last week to allow work on the service structures to now begin. Further back from the pad, the crew tower has already seen repairs to the minor damage it suffered and we look forward to finally using it in 2020!
Kerbal Space Agency
@KSA_MissionCtrl
latest update from Wernher von Kerman is that they have found a way to stably release the stored energy however they are still working to slow the discharge rate - dropping to long-lasting levels brings back "violent instability" twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
earlier today at 17:06 UTC almost 600km southeast of ATN Central, Zosimus began its fourth pass through the atmosphere. Astronomers are again attempting to look for it with the ATN Central IR scope for early confirmation of whether it still survived
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h10m] Flight Director Lanalye has gathered her team for pre-launch briefing. Since Ascension missions are on hold, the A team will fire these last two launches while B team is held in reserve. As usual, basic Mk6-I mission plan will be in use
Kerbal Space Agency
@KSA_MissionCtrl
topped off once again in the VAB, next week's Progeny Mk6-I rocket undergoes load checks to ensure all couplers are structurally sound. Lead Engineer Simon reports some VAB workers have been tasked back onto the Ascension parts to the rear to ready the Mk1 we hope to fly in Jan

bouncing radio waves off the ionosphere helps us stay in touch with far-flung surface expeditions but it's not the most reliable method of communication. Next year hopefully we will have satellites in orbit for better contact en.wikipedia.org/wiki/Skywave
Kerbal Space Agency
@KSA_MissionCtrl
in order to meet more stringent safety regulations that have begun to go into effect by KSA upper management, future Ascension Mk1 capsule flights will also carry radial chutes up near the top as backup in the unlikely event of a *complete* main chute failure
Kerbal Space Agency
@KSA_MissionCtrl
Head of R&D Wernher von Kerman reports that although his engineers worked hard, they could not come up with a more powerful LES for last-ditch chute failure recovery which could also remain the same size and still fit atop the Mk1 capsule
Kerbal Space Agency
@KSA_MissionCtrl
OFU-009(A) has been captured! It's on the Ops Tracker designated bit.ly/Zosimus, ancient Kerbskrit for "viable" or "likely to survive" - which its discoverers bet on happening after its aerobrake. Unfortunately the namesake will not hold & it will eventually hit Kerbin
Kerbal Space Agency
@KSA_MissionCtrl
early end to the week, everyone is ready to kick back for the weekend after the successful end to the first Kerbal Sounding Project launch campaign. 2 more next month! Also the ASA report was released today & we have all the details in our Ops Summary: kerbalspace.agency/?p=10060
Kerbal Space Agency
@KSA_MissionCtrl
all 4 astronauts are working closely with the Ascension design team in charge of the Mk1-B capsule, which will be more capable of returning from higher altitudes with less Gs & also being able to withstand re-entry heat longer with the shallower re-entry profile
Kerbal Space Agency
@KSA_MissionCtrl
final stacking of the Mk6-I took place earlier today in the VAB so checks could be carried out on load-bearing parts. All work on the Ascension side, seen in the background, has remained paused until at least next month when Progeny assembly winds down
Kerbal Space Agency
@KSA_MissionCtrl
the Air Safety Administration has confirmed it completed its investigation into the Deuce crash but has more work to do with law enforcement officials before the report can be released - hopefully by the end of this week
Kerbal Space Agency
@KSA_MissionCtrl
pad resurfacing has gotten underway as cracks had formed from the blast concussion. If any rocket engine exhaust gases forced themselves under the surface, they would gouge the underlying soil and possibly blow out a portion of the pad, damaging the structures & rocket
Kerbal Space Agency
@KSA_MissionCtrl
arrests have been made as the investigation into the attack on our launch pad continues to move forward. Those accused of collaborating with the exiled radicals will be offered plea bargains for cooperation in shutting down their local support network
Kerbal Space Agency
@KSA_MissionCtrl
we gave into some light speculation on the news about the Deuce aircraft and also have some more info on future Ascension plans now that the pad repair process can begin. That and more which transpired this week in our Ops Summary: kerbalspace.agency/?p=10044
Kerbal Space Agency
@KSA_MissionCtrl
a final report has been submitted by Lead Engineer Simon after review of the launch pad damage. It will take at least the remainder of the year - we need to make major repairs with minor replacements, but hopefully we can kick off 2020 with an Ascension launch!
Kerbal Space Agency
@KSA_MissionCtrl
the final K2-X static fire testing of 2019 went well today on the vertical test stand, proving that the engine will be capable of lifting the Ascension Mk2 up into (hopefully) orbit. It will be returned to the VAB next week for refurbishment
Kerbal Space Agency
@KSA_MissionCtrl
we have no official statement to give in response - we have cooperated with the ASA in giving them access to the aircraft debris from the launch pad but that is the extent of our involvement. Lots of questions tied to this revelation will certainly take more time to answer
Kerbal Space Agency
@KSA_MissionCtrl
KNN reported a leak from the ASA investigation into the wreckage of the Deuce that crashed into our launch pad: conclusive evidence has been found that it is the plane reported missing earlier this year. The remains of the sole occupant who piloted the plane have yet to be ID'd
Kerbal Space Agency
@KSA_MissionCtrl
thanks to increasing support from our bit.ly/KSA_Patreon donors, CFO Mortimer says all the unplanned expenses of Oct in addition to some new R&D didn't leave us as deep in the red as we could have been. Financial report is available here: docs.google.com/spreadsheets/d…

@KSA_MissionCtrl
Lead Engineer Simon reports from the Vertical Assembly Building that the Progeny integration is well on the way to being back on track to meet the updated launch schedule now that they've sidelined all Ascension work for the time being
Kerbal Space Agency
@KSA_MissionCtrl
everyone is eager to get back to work at KSC this week, starting today. A team has already been assembled by Lead Engineer Simon to begin assessing the damages done to the launchpad and service structures. They plan to submit a report by the end of the week
Kerbal Space Agency

we hear Jeb has been making overtures in an attempt to get to drive the Mobile Launch Platform. He once managed to finagle his way into the drivers seat of the Progeny carry vehicle but we doubt he'll ever get a chance to go behind the controls of the MLP - even w/o a rocket atop
Kerbal Space Agency
@KSA_MissionCtrl
NovaPunch has informed us the final K2-X delivery for this year is ready for us to receive once KSC is operational again. This will be the engine that will fly the first Ascension Mk2 rocket and will be static fired next week on the vertical test stand
Kerbal Space Agency
@KSA_MissionCtrl
unlike the Progeny Mk6 missions (not Mk7), which can be launched from the North Field, Ascension rockets require the launch pad and all future missions are on indefinite hold until we can fully assess the damage that was done to the pad and service structures
Kerbal Space Agency
@KSA_MissionCtrl
the radome has been completed on the tall hills west of KSC and will be hooked up to the Tracking Station by tomorrow, which means we can return to KSC next week! Due to security, it's tough working remotely for engineering and R&D teams w/o full file access
Kerbal Space Agency
@KSA_MissionCtrl
R&D Head Wernher von Kerman has presented a new instrument suite to the Progenitor team, suitable for launch on a future Progeny Mk7 now that the payload section can point & hold orientation. Ascension is also interested in larger related instruments for an orbital payload
Kerbal Space Agency
@KSA_MissionCtrl
although the record high Gs sustained by Cdr Val on her last mission were not harmful, they were quite uncomfortable and could be more tolerant with training. A centrifuge is being planned for construction either on the KSC R&D campus or near our HQ underground in Umbarg
Kerbal Space Agency
@KSA_MissionCtrl
KSC remains shut down but a team is onsite this week collecting debris from the launch pad so the ASA can begin to determine the origins of the aircraft based on the parts that are recovered. A lot remains intact, including the cabin & body of the unidentified pilot
Kerbal Space Agency
@KSA_MissionCtrl
we teased some info about the Ascension Mk3 in one of last month's Ops Summaries. The full design spec is:
• 1.25m TVC vacuum engine
• More powerful 1.25m lifter engine
• Actuating guidance fins
• Multi-segment (reusable?) SRBs
Current flight target mid-2020

funeral services have begun this weekend and will continue throughout the week for the pad workers that perished in the fire last week. Cpt Jeb has committed himself to attending as many as he can to personally offer his condolences as the sole survivor
Kerbal Space Agency
@KSA_MissionCtrl
it's been a pretty crazy week and we have no new information to share on the attack investigation, but if you happen to just be catching up on things our Ops Summary still has all the vital details: kerbalspace.agency/?p=9979 Please keep those lost this week in your thoughts
Kerbal Space Agency
@KSA_MissionCtrl
all of our astronaut crew have been cleared in their psychiatric evaluations, although Bob says he really didn't need more to be anxious about. Jeb told him not to worry, he's not about to let him rotate into command next mission and wants another shot at space soon
Kerbal Space Agency
@KSA_MissionCtrl
.@mrtagnan there's no radar coverage until the tracking vessel comes on station later in the count. We've only cared about range issues for a rocket going up & hitting something, not the other way around. They chose their window of attack wisely. This is why we are now building our own radar station
Kerbal Space Agency
@KSA_MissionCtrl
video was adjusted for brightness & contrast but it all still happens pretty fast - aircraft comes gliding in from the left @ upwards of 100m/s & Jeb's capsule goes flying off to the right (you can make out the LES motors firing)
Kerbal Space Agency
@KSA_MissionCtrl
we have released our own video of the Deuce that flew into the Ascension Mk1. Monitoring cameras were activated once fueling operations began. It came in lights off & engines off - there was no warning & only the automated LES saved Jeb's life
Kerbal Space Agency
@KSA_MissionCtrl
TL;DR (it is a lot to take in) - our current stance is to work to determine all the details of how this attack was carried out and put in place measures to prevent future attempts. We are not backing down nor is any action yet able to be taken against those responsible
Kerbal Space Agency
@KSA_MissionCtrl
TL;DR - a sect of violent Monolithic followers remains set against our space-bound ambitions even after being secretly banished to the other side of the planet by religious leaders, where they happened upon a large unknown population of kerbs receptive to "salvation"
Kerbal Space Agency
@KSA_MissionCtrl
while a lot of work remains in the investigation, all parties involved feel a point has been reached where we can release a statement not only on the events of this past week but the events of the past few years that led up to this brazen attack: kerbalspace.agency/?p=9965
Kerbal Space Agency
@KSA_MissionCtrl
planes are no longer grounded after the Air Safety Administration completed its inventory & confirms there are no missing aircraft that have been produced and registered, except for those already lost. A No-Fly Zone currently exists around KSC to 20km in all directions
Kerbal Space Agency
@KSA_MissionCtrl
our recovery vessel MSV Aldeny was recently fitted with advanced radar capabilities to serve as tracking & recovery for the upcoming Mk6 launches and has parked off our south shore to keep watch on the skies until a proper ground facility can finish construction next week
Kerbal Space Agency
@KSA_MissionCtrl
we're still trying to wrap our heads around what happened yesterday and have been greatly comforted from the support shown by the public. We are also providing grief counselors to any KSA staff that require them. Our astronaut crew will all receive mandatory psych evals
Kerbal Space Agency
@KSA_MissionCtrl
a team of volunteers returned to KSC to recover the capsule and lock it up in the VAB. They report substantial damage to the launch pad from the fire and although the service structures are still standing the blast has likely rendered them inoperable
Kerbal Space Agency
@KSA_MissionCtrl
investigation work continues but one thing we can do now is recognize the brave kerbals that raced towards the launchpad fire to attempt a rescue of any survivors. Sadly, there were none and the 12 workers still on the pad is our greatest loss of life during a mission to date
Kerbal Space Agency
@KSA_MissionCtrl
our founder and Operations Director @DKerman_KSA has already gone on record via a short interview with KNN saying "we will not in any way be deterred by such a heinous action as occurred today and we shall cooperate fully with a joint investigation"
Kerbal Space Agency
@KSA_MissionCtrl
due to the KNN broadcast from earlier today we are unable to release a full statement as planned now that the investigation into today's events is no longer under our sole jurisdiction. We have agreed to work jointly with government and religious leaders
Kerbal Space Agency
@KSA_MissionCtrl
we have no comment on the video recently broadcasted by KNN except to say Jeb is indeed alive & safe, we are aware that this was a targeted attack using a Deuce aircraft and are continuing with our own internal investigation
Kerbal Space Agency
@KSA_MissionCtrl
Further details on what exactly happened at KSC will be released later today once a review is conducted by KSA management at our corporate HQ here in Umbarg. While he's understandably frustrated to not be going to space today, Captain Jeb is also thankful to be alive
Kerbal Space Agency
@KSA_MissionCtrl
KSC and all surrounding areas have been completely evacuated with no further injuries or loss of life. An observation team left at the tunnel entrance reports the launchpad fire is burning down and not spreading. No other surface activity is reported in the area
Kerbal Space Agency
@KSA_MissionCtrl
Jeb was extracted from the capsule with no injuries & sent off with the evacuation. Rescue operations at the launch pad have also ceased, sadly no survivors were found. The fire that has grown since the initial explosion as remaining fuel ignited will be left to burn out
Kerbal Space Agency
@KSA_MissionCtrl
we are purposefully withholding details at this time as a security measure and *will not* be answering any questions until we are able to make a complete and formal statement. All staff & visitors are receiving evacuation instructions & are expected to comply
Kerbal Space Agency
@KSA_MissionCtrl
additionally a full evacuation of KSC, the neighboring Support Village and even camped out Monolith pilgrims has been ordered. All but staff needed for the pad rescue operation and Cpt Jeb's recovery will be departing immediately to Umbarg via the access tunnel
Kerbal Space Agency
@KSA_MissionCtrl
we have declared an emergency at KSC after the rocket exploded on the launch pad a few minutes ago. The LES tower has successfully carried Jeb away and he is currently descending under chute ~800m away. Right now our focus is on rescuing any pad workers that may have survived
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h40m] the rocket's tanks are topped off & pad crew is unhooking the tanker truck to begin clearing the pad for launch. Pre-flight operations continue, with Monolith chill down apparently successful again as no weather alerts have been issued
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h55m] Launch Control have confirmed pad workers have configured the rocket for tanking operations and given the GO to begin onloading 7t of liquid propellants while Jeb has also confirmed arming of the Launch Escape System
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h10m] we have GO from the weather desk to begin preflight operations. Rocket has been woken up, controllers are preparing to onload flight software while Jeb begins to configure his capsule instruments. Software update details: bit.ly/AFCS_ChangeLog
Kerbal Space Agency
@KSA_MissionCtrl
Jeb & Bill were reportedly deep into a discussion on the possibility of attaching rockets to drag racing cars as mounting wrapped up and Bill had to pull out his intercom to return to Launch Control and begin setting up his console for preflight
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h40m] FD Lanalye and her Launch Team A have assembled in Launch Control for final mission briefing. Some minor ascent corrections have been made based on Val's flight but overall the mission is the same - gather more data on kerbal physiology while in 0G
Kerbal Space Agency
@KSA_MissionCtrl
without much Genesis activity, launches have been the only weather-dependent operations so we haven't spoken a lot about the weather lately. Overall it's been mostly rainy & windy this past week so we are thankful for better conditions arriving recently
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h10m] as the rocket mounting continues, meteorologists are gathering weather reports from regional sources (airships, weather stations, maritime vessels) to put together an updated launch forecast. Yesterday we had 85% GO with improving conditions expected
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h20m] crew loading has been completed on schedule and the rocket will now be raised back vertical and mounted again so preflight operations can begin. Bill is plugged into the capsule via intercom in case Jeb notices any problems from inside
Kerbal Space Agency
@KSA_MissionCtrl
Flight Director Lanalye had a quick consultation with Lead Engineer Simon about Jeb walking out onto the tank and was assured there is no danger as a result. She still formally complained to Ops Dir Drew who just sighed & threw out his arms like "what're we gonna do?" Jeb is Jeb
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h45m] despite the pad crew's objections, Jeb refused to come down until his photo was taken. The hatch has since been opened and Jeb is now clambering aboard with assistance from the pad workers & Specialist Bill, who will be running CapCom today
Kerbal Space Agency
@KSA_MissionCtrl
[L-5h] the countdown has officially begun! Jeb has exited the Astronaut Complex and boarded the crew shuttle for the launch pad, leaving Bob in the ready room in case he is needed at any point prior to launch. Expect updates from us at these major milestones in the count
Kerbal Space Agency
@KSA_MissionCtrl
Bob & Jeb are suiting themselves up - they fly in the same pressure suits worn for atmospheric missions because even with a capsule pressure loss they won't be in space long enough to lose suit integrity. They only really need to help each other with their helmets
Kerbal Space Agency
@KSA_MissionCtrl
ahead of 2nd sunrise, launch crews are on their way to the pad to get the rocket unmounted and lowered for Captain Jeb to climb aboard later in the day cycle. Both he and Bob are already awake and getting ready for their choice breakfast meals prior to suiting up

@KSA_MissionCtrl
all launch readiness reports have been reviewed and signed off on by Operations Director @DKerman_KSA which means we are GO for launch attempt tomorrow! Jeb says he probably won't sleep much. Bob agrees, but not for the same reasons. Prelaunch ops kick off @ 13:25 UTC
Kerbal Space Agency
@KSA_MissionCtrl
down-range tracking at Ockr and Sheltered Rock, which use 500km aerials like this one at Umbarg, have reported good comms checks. Our recovery vessel MSV Aldeny has already left port in Sheltered Rock to sail over 500km for the recovery zone east of Ockr
Kerbal Space Agency
@KSA_MissionCtrl
Flight Director Lanalye & her A team are now conducting a wet dress rehearsal as part of today's launch readiness, which fuels the rocket, runs up to L-30min in the countdown to ensure all pad systems are functioning, the rocket is hooked up properly & any issues can be found
Kerbal Space Agency
@KSA_MissionCtrl
the launch pad may have changed, the rocket may have changed, but ever since this first mounting the procedure has remained largely unchanged. Jeb's rocket is now undergoing the process after being rolled out to the pad earlier this day cycle
Kerbal Space Agency
@KSA_MissionCtrl
both of our crew in quarantine remain healthy. Jeb says he wishes the mission was tomorrow - he's tired of doctors poking him. Bob admits he's still working through some minor anxiety issues and is hoping Jeb doesn't suddenly come down with an illness
Kerbal Space Agency
@KSA_MissionCtrl
although they have access to a phone line to talk, Val & Bob are instead playing a game of pictograms through his window. Jeb says it's disgustingly cute & is glad they don't have adjacent rooms so he wasn't asked to join. Bob says he wouldn't have asked anyways
Kerbal Space Agency
@KSA_MissionCtrl
wow that was a week already? Time flies when you're having fun, or are just excited like we are for another kerbed space mission next week! Get hype! Also get caught up on all that went down at KSC the past week: kerbalspace.agency/?p=9945
Kerbal Space Agency
@KSA_MissionCtrl
we have another solidly-built rocket ready for rollout next week! Great job to Lead Engineer Simon and his team in the VAB, who worked tirelessly to get the lift stage ready on short notice when we flipped around the launch schedule
Kerbal Space Agency
@KSA_MissionCtrl
mission training is complete, Captain Jeb & Specialist Bob are now in quarantine in the Astronaut Complex until launch day, allowing for them to rest after their vigorous training schedule and remain under close medical observation
Kerbal Space Agency
@KSA_MissionCtrl
impact speeds would likely still be too high however, beyond the tolerance of the capsule to withstand unless it were built to do so, which would add too much mass. Instead we are looking into a slightly more powerful LES tower - still adds more mass but not as much
Kerbal Space Agency
@KSA_MissionCtrl
the procedure would be to drop the heat shield & vent all remaining cold gas to reduce mass. Next the flotation device would be deployed to create more drag (tho it could possibly rip apart). Finally the push motors would be fired just before impact
Kerbal Space Agency
@KSA_MissionCtrl
with enough data from re-entries of the Mk1 capsule, Ascension engineers have been able to model the possibility of using the 4 LES push motors as a last-ditch attempt at survivable recovery should the chutes completely malfunction. Result: probably not
Kerbal Space Agency
@KSA_MissionCtrl
load checks are complete for the latest Ascension Mk1 - tomorrow it will be laid back horizontal and given a detailed final inspection over the next two days and if all looks good it will then be loaded up onto the carry vehicle for rollout on Monday
Kerbal Space Agency
@KSA_MissionCtrl
once again Jeb comes out victorious in number of successful sim runs during training, which is wrapping up this week. Jeb says Bob thinks too much when things start to go sideways (sometimes literally) whereas he just "does what needs to be done"
Kerbal Space Agency
@KSA_MissionCtrl
the existing 0.625m SRB by Umbra Space Industries has been incorporated into the first dual-segment SRB and will be worked into the design of the Progeny Mk7-B for launch in early 2020. Same surface area, so same thrust, but slightly better nozzle design for higher ISP
Kerbal Space Agency
@KSA_MissionCtrl
reports from a recent surface expedition claim to have found the crash site of the missing Deuce aircraft - or at least, evidence of a crash site because the plane itself has still not been found. The news will report anything these days it seems, and this is still a hot story
Kerbal Space Agency
@KSA_MissionCtrl
a good static fire of the newest K2-X engine was performed today on our test stand in the R&D complex. It will be returned to the VAB for inspection & if all checks out then replacement of its ignition system and integration with its flight hardware later this month
Kerbal Space Agency
@KSA_MissionCtrl
so it's not actually holding the capsule down on its own very much. If it fails to release automatically and the manual release also fails, the LES push motors have enough force to yank the capsule free once the rocket is in space
Kerbal Space Agency
@KSA_MissionCtrl
the decoupler's main job is actually to hold the capsule away from the fuel tank during ascent - the force of it atop the tank alone would crush it. The decoupler has strong cross-braces that sit under the capsule & distribute stress to the tank sides, which are strongest
Kerbal Space Agency
@KSA_MissionCtrl
Jeb's Ascension Mk1 was integrated with its engine last week and will go vertical today in the VAB so the capsule can be lifted up, placed on top and load checks carried out on the decoupler and heat shield. It's always best to find problems before launching...
Kerbal Space Agency
@KSA_MissionCtrl
another productive week behind us, we hope you all can say the same. Recap what went on in our Ops Summary: kerbalspace.agency/?p=9932 Have a great & relaxing weekend, everyone!
Kerbal Space Agency
@KSA_MissionCtrl
the MLP is now parked in front of the VAB after a successful fit test at the launch pad. It will remain there until needed for the Mk2 in Dec, although additional driver training exercises will also be conducted between now & then. here's a look back at the 2-month assembly
Kerbal Space Agency
@KSA_MissionCtrl
with Bob being even more of an intellectual than Val, Jeb has had trouble getting along with him during training. Jeb likes to call him "Bob the Brain". It's gotten so bad we've actually separated them, which still works fine overall since they aren't on mission together
Kerbal Space Agency
@KSA_MissionCtrl
the Mobile Launch Platform is on its way out to the launch pad to park as if it were carrying a rocket to hook up to the service towers and ensure that platform height is good, proper spacing between treads and towers, etc. It actually moves pretty fast unladen @ ~11m/s
Kerbal Space Agency
@KSA_MissionCtrl
Lead Engineer Simon was happy to report today that they finally got all the issues worked out and were able to drive the Mobile Launch Platform out of the HAB. Lots more shakedown work remains of course but it will eventually make its way over to the launch pad for fit tests
Kerbal Space Agency
@KSA_MissionCtrl
this week has mainly been water recovery exercises for Jeb and Bob just offshore from KSC. We don't need our actual recovery vessel MSV Aldeny, berthed at Sheltered Rock, because they aren't training to be hauled up in the capsule onto the deck as if everything went right
Kerbal Space Agency
@KSA_MissionCtrl
the unkerbed Mk1 that will be testing the new larger guidance fins next month will also carry another RTG test payload since the Mk7-A mission did not fully qualify the casing as planned. This will debut the enlarged 1.25m PLF (PayLoad Fairing) assembly as well
Kerbal Space Agency
@KSA_MissionCtrl
although the Mobile Launch Platform was successfully fired up today, Lead Engineer Simon & his team were unable to get it rolling as planned. They have identified several problems that need to be fixed but remain confident they can have it out of the HAB this week
Kerbal Space Agency
@KSA_MissionCtrl
the second of three K2-X engines from our order placed back in May has been delivered. Originally slated for Jeb's mission, with the schedule reshuffle it will now be assigned to the Mk1 orbital guidance test rocket due to launch in November
Kerbal Space Agency
@KSA_MissionCtrl
it's important to admit that we mostly *think* we know what we're doing when it comes to rocketry. We only *know* what we are doing when what we think we're doing actually *works* to within an acceptable margin of accuracy. We are mostly doing a lot of thinking these days
Kerbal Space Agency
@KSA_MissionCtrl
with the installation of the SRB support stands the Mobile Launch Platform is practically complete! There are still some minor tasks to wrap up but it could be powered up and moved out of the HAB as early as tomorrow, reports Lead Engineer Simon
Kerbal Space Agency
@KSA_MissionCtrl
what's different in the production MLP vs the original design? A second control cab was added to the opposite side of the platform so it can be driven forwards and backwards without having to turn around. Which it *can* do, but driving straight is easier
Kerbal Space Agency
@KSA_MissionCtrl
Specialist Bill, primary CapCom and Commander Valentina, his backup, have started their mission training with the Launch Control A team today. We place astronauts in these roles since they are best suited to quickly communicating complex instructions in a way they would also understand
Kerbal Space Agency
@KSA_MissionCtrl
weekend, ho! October is only just getting started and we already have plenty of things to talk in more depth about in our weekly Ops Summary, so check it out - kerbalspace.agency/?p=9885 everyone have a relaxing weekend & try to take some time to gaze up at the night sky
Kerbal Space Agency
@KSA_MissionCtrl
the mysterious disappearance of a Deuce back at the end of May has actually increased enrollment in ASA flight school - kerbs have realized more than ever just how big the surface world is & how much there is to explore, which airplanes can do well. Plus some are still searching
Kerbal Space Agency
@KSA_MissionCtrl
September may have been a rough month financially, but we remain in decent standing with just enough funds to complete our planned operations for the year. Thanks as always to our bit.ly/KSA_Patreon supporters! docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
still, this was much less than the level of tolerance that was planned to be demonstrated so we still need a good result from the Kerbin I impact from orbit to fully certify the RTG casing as safe to actually carry radioactive material and power future orbital satellites
Kerbal Space Agency
@KSA_MissionCtrl
more good news for our future orbital missions, the RTG casing from last week's mission has been carefully inspected and does not show any more damage than expected from an impact at the speeds it endured, estimated to be at over 100m/s
Kerbal Space Agency
@KSA_MissionCtrl
the lift stage for the Mk2 will begin its conversion to a Mk1 this week, simply by removing the decouplers that are meant to hold the solid rocket motors the Mk2 needs to help boost it off the pad. This will be the lifter for Captain Jeb's flight later this month
Kerbal Space Agency
@KSA_MissionCtrl
the 60m dish will be built in late 2020/early 2021 once the North & South ATN/DSN complexes are complete and operational. The 18m dishes will be installed as needed to handle increasing orbital traffic and relieve the 27m dishes for deep space missions
Kerbal Space Agency
@KSA_MissionCtrl
let's have a look at the various communication dishes in use (or planned to be) around Kerbin. When deep space missions come around, we plan to work out a way to combine our three 7m dishes for greater reception rather than just upgrade them to bigger sizes - initially anyways
Kerbal Space Agency
@KSA_MissionCtrl
Ascension team have announced a date for Captain Jebediah's mission - launching 10/22 @ 18:25 UTC! He and his backup Specialist Bob have already begun their mission training this week consisting so far of simulator runs and emergency capsule egress drills
Kerbal Space Agency
@KSA_MissionCtrl
the Mobile Launch Platform continues to work towards completion, with the main deck being finalized this week. Anyone notice something different not in the original design renders? Also, the Dhumla continues to be built towards completion next month as well
Kerbal Space Agency
@KSA_MissionCtrl
flight analysis for Cdr Val's mission has been posted. Just a few ascent design issues to clean up next time. We are also actively working to resolve an issue in LVD we discovered while doing this analysis: kerbalspace.agency/?p=9878
Kerbal Space Agency
@KSA_MissionCtrl
something else the Progeny Mk7-A tested for Ascension Mk2 on its last flight was steering limits on the guidance fins. Until the Mk2 drops boosters, the fins can't actuate too far without hitting the decouplers! github.com/KSAMissionCtrl…
Kerbal Space Agency
@KSA_MissionCtrl
all hail the week end! Rocketry crews will be enjoying a well-earned break next week before the lead up to the next launch in October. See what else has transpired and get more information via our Ops Summary: kerbalspace.agency/?p=9834
Kerbal Space Agency
@KSA_MissionCtrl
even without the recovery of the RTG casing, the mission still proved the Ospray engine capable of controlling the rocket via thrust vectoring and the guidance fins also gave engineers more data for the larger versions that will go on the Ascension Mk1 & Mk2
Kerbal Space Agency
@KSA_MissionCtrl
ignition and LIFT OFF!! 3.6Gs of force pushes the rocket clear of the VAB's shadow as it tips over, clearing the towers and aiming downrange along a heading of 45.5°. 35s from now will see MECO-1 and stage separation followed by a coast phase up to 15km before MES-2
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h40m] Flight Director Lanalye has assembled her B team for their final mission brief. The Mk7-A has been modified from original spec to remove the chute and instead carry an additional payload within a new fairing shell that we plan to also use on Ascension rockets
Kerbal Space Agency
@KSA_MissionCtrl
all launch readiness reviews have been submitted & approved by Operations Director @DKerman_KSA - we are 🚀 GO FOR LAUNCH 🚀 tomorrow. Pre-launch ops will commence at 12:15 UTC. Forecast has weather at 65% GO - depends largely on what a storm out at sea does
Kerbal Space Agency
@KSA_MissionCtrl
it took a while but we finally put together a video for the Ascension Mk1 using footage & images from Cdr Val's flight - even managed to store a bit more video during ascent finally. Sound on! Enjoy, and just imagine the Mk2... youtube.com/watch?v=ZukOY_…
Kerbal Space Agency
@KSA_MissionCtrl
complete ascent profile for last week's flight. So close! The large deviation near 45° was due to an overly-conservative guidance setting to level off the rocket. Deviation at end was an oversight, guidance unlock at MECO as original plan was to burn out of atmosphere
Kerbal Space Agency
@KSA_MissionCtrl
primary crew Cpt Jeb and his backup Spc Bob have begun basic mission prep this week with the Ascension team, which will outline objectives while reviewing and analyzing data from the previous mission. This will culminate in a launch date after the flight report releases
Kerbal Space Agency
@KSA_MissionCtrl
although her parade isn't as big as Bill's was in the current capital Sheltered Rock, the welcome Val is getting at Kravass is much more personal being it's her home cavern. The local government will be awarding her a keystone to the city for her many accomplishments
Kerbal Space Agency
@KSA_MissionCtrl
a final photo from Commnder Val's mission, after she was strapped back down. Prior to re-entry she had to roll the capsule "up" so her bottom was towards Kerbin. This left her with a view out into the cosmos. The Great Expanse - we'll get there someday...
Kerbal Space Agency
@KSA_MissionCtrl
learn more about today's decision to delay the Mk2 orbital attempt in our weekly Ops Summary: kerbalspace.agency/?p=9801 Have a great weekend everyone, and we look forward to this one especially at KSC. Anyone know why?
Kerbal Space Agency
@KSA_MissionCtrl
have a look at the first 50 rockets we launched since operations began in late 2016. Some are just mounted but all are individual rockets at the start of their missions. Some exploded - but of course that is to be expected at times. Here's to 50 more! 🥂
Kerbal Space Agency
@KSA_MissionCtrl
basic reason is better guidance comes with less fin angle, but more fin angle is needed to fly the planned orbital trajectory so Ascension will wait to get better data on Progenitor's steerable fins after this month's launch, then scale them up for the Mk2
Kerbal Space Agency
@KSA_MissionCtrl
after this past week's mission, the Ascension team leads had a two-hour meeting and brought their concerns to Operations Director @DKerman_KSA, who made the decision that we are going to bump the Mk2 flight to December & move Jeb's Mk1 up to late October
Kerbal Space Agency
@KSA_MissionCtrl
Support Village airship tether is now occupied by another cargo carrier, this time bringing us supplies along with the capsule and Commander Val, who won't be sticking around long as she has media engagements this weekend in Umbarg & Kravass
Kerbal Space Agency
@KSA_MissionCtrl
Val's last photo before she had to leave the window and strap in for re-entry as the capsule passed down below 200km. If you look closely at the bay that is cut off by cloud cover, over the water is the lift stage way off in the distance
Kerbal Space Agency
@KSA_MissionCtrl
things are known to be stormy north and south of the equator and this massive system (two systems colliding??) to the north of Sheltered Rock, seen from 250km, certainly gives everyone a new perspective on the scope of these weather events
Kerbal Space Agency
@KSA_MissionCtrl
once she was unstrapped, Commander Val could get a better view out her window, seen here looking along her direction of travel past Sheltered Rock and Ockr. Minmus is rising over the horizon and the capsule is passing through 160km on its way to apokee
Kerbal Space Agency
@KSA_MissionCtrl
work on the Mobile Launch Platform has moved forward in the HAB, with the engines finally installed along with the treads that will carry it across the ground. Next up will be the command cab and the remainder of the main deck, which needs more rails, ground access and lighting
Kerbal Space Agency
@KSA_MissionCtrl
one cool bit that may not be immediately obvious from the flight telemetry is check out the G readout while in space. Yup, you can see Val moving the capsule around. Each thruster only generates 0.02kN of force
Kerbal Space Agency
@KSA_MissionCtrl
initial telemetry data review has also clinched Val the new bit.ly/KSARecords for time in space at 11m2s while also claiming the new record for a kerbal's height over Kerbin at 251.907km. Jeb, obviously, is keen to break these on his flight
Kerbal Space Agency
@KSA_MissionCtrl
the complete telemetry data for Val's flight is now available: docs.google.com/spreadsheets/d… we've also got her pictures and will be going through them as part of the flight analysis. Here is one just after lift stage separation, looking back towards KSC
Kerbal Space Agency
@KSA_MissionCtrl
MSV Aldeny has been docked and crew offloaded in Sheltered Rock. Val will remain there for medical checkups and return with the capsule on a supply airship Friday. Jeb is stoked to hear that his flight for early November has been confirmed, exact date TBD
Kerbal Space Agency
@KSA_MissionCtrl
post-launch operations have concluded, weather balloon returned, pad remains in good shape, controllers have gathered up all their terminal data & will receive the capsule data tomorrow along with images from Val's camera. Next launch is the Progeny Mk7-A in just over a week!
Kerbal Space Agency
@KSA_MissionCtrl
arriving just after sunset, capsule was located, hooked & pulled aboard MSV Aldeny. One of the deck crew thought it gallantrous to pick Val up out of the capsule - yea he won't ever try something like that again, suffice to say. Aldeny should arrive at Sheltered Rock early tmrw
Kerbal Space Agency
@KSA_MissionCtrl
at last the recovery vessel was in visual range of the capsule when it deployed full canopy! Photo taken through the eyepiece of the high powered scope, bumped a bit. Attempting to re-center lost tracking and the capsule fell below the horizon. Still, not bad!
Kerbal Space Agency
@KSA_MissionCtrl
as much as our crew seem to desire a swim after the mission, procedure dictates they stay put until Aldeny hauls the capsule up the ramp onto their deck. Ending up in the water is only in case of an emergency, and their suits can pressurize to keep them afloat
Kerbal Space Agency
@KSA_MissionCtrl
✨KERZZAH!!!✨ Mission success, with Val back on the surface safe & sound! MSV Aldeny is about 45min away making best speed to the landing site. Everyone busy congratulating each other in the control room. Val says she wants to get out, float & feel weightless again
Kerbal Space Agency
@KSA_MissionCtrl
contact! Radio blackout lasted 33s and Val came back "read you loud & clear!" on the first attempt. We have confirmation of LES jettison and initial chute deployment. Updated telemetry coming in shows Val only had to sustain +10G (max 11.4) for 6 seconds
Kerbal Space Agency
@KSA_MissionCtrl
tense moments in mission control as static crackles through the comm speakers from ionized air blocking radio transmission as the capsule plunges through the atmosphere in excess of 1.9km/s, heating the external surface to over 1,000°F (>550°C). Bob will call out for Val soon
Kerbal Space Agency
@KSA_MissionCtrl
secured back in her seat, Val is proceeding through the checklist for re-entry. SAS guidance enabled to hold retrograde, she has rolled the capsule "up". LES jettison armed, chutes armed - controllers deemed separation distance good from lift stage. Atmo in <2min!
Kerbal Space Agency
@KSA_MissionCtrl
getting the capsule reoriented Val was still able to barely spot the lift stage out the window. Controllers are debating whether she should make additional maneuvers to put some more distance between the two craft - a collision on re-entry would be catastrophic
Kerbal Space Agency
@KSA_MissionCtrl
after passing through 251.907km apokee, only 47km lower than planned, Val is reluctantly leaving the window to strap back in and begin preparing for re-entry. New trajectory has been plotted and MSV Aldney is already on the move towards the new recovery zone ~35km west of target
Kerbal Space Agency
@KSA_MissionCtrl
Val has unstrapped to get a better view out the window. Not really much room to float around inside the cramped capsule but you can still float. Like Bill, she reports no negative effects on her breathing, vision, swallowing, etc. Flight Surgeon reports her vitals are nominal
Kerbal Space Agency
@KSA_MissionCtrl
with just over 4min to apokee, Val will spend more time in space on her way up than Bill did his entire flight! She currently has the capsule under manual control and is spinning about to take in the sights through the window, camera at the ready
Kerbal Space Agency
@KSA_MissionCtrl
MECO was 3km short of planned altitude but overall an extremely nominal ascent! Capsule is adrift after separation & Val confirms guidance is released properly and she has full control of both the RCS and SAS systems
Kerbal Space Agency
@KSA_MissionCtrl
some turbulence passing through the upper atmo bumped Val around a bit but overall pitch & heading remained nominal. Control authority remains good as rocket is approaching 40km and Val is prepping for "the kick" as the engine will throttle up to full w/ 3.6Gs
Kerbal Space Agency
@KSA_MissionCtrl
rocket has passed thru MaxQ & is supersonic, guidance is looking the best we've ever seen this early in the ascent - nominal pitch over, nominal heading. Engine parameters nominal. Val is dutifully reading out her instruments to ensure we're getting good data
Kerbal Space Agency
@KSA_MissionCtrl
Ignition sequence was good - LIFT OFF of the 9th Ascension Mk1, carrying Commander Valentina skyward to become the second kerbal in space!! Rocket will throttle up as it clears the towers, maintaining 1.65 TWR as it rolls onto 54° heading and begins to pitch over downrange
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] live telemetry will be loading shortly - ops.kerbalspace.agency Val is ready, eyes locked on her panel to call out readings during ascent. Final GO/NO GO at T-30 before automated launch sequence begins. Hang on Val! Get ready.... get set....
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] we have arrived at the terminal count, AFCS is now in command - Val has manual controls she should not have to touch during ascent. Service tower boom has swung away leaving the rocket on internal power & life support, RF comm check underway
Kerbal Space Agency
@KSA_MissionCtrl
Flight Surgeon reports Val is finally showing an elevated heart rate, but at this stage that is considered normal and anything else would have been cause for a bit of concern - anyone who is not at least a little afraid generally tends to make bad decisions
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] Final readiness polls complete: Wx: GO; Range: GO; Flight: GO; Tracking Station: GO; Downrange Tracking: GO; Ops Director @DKerman_KSA: Launch permission granted! 🚀GO ASCENSION🚀 FTS power internal, service tower boom unlocked for retraction, AFCS rdy for terminal count
Kerbal Space Agency
@KSA_MissionCtrl
flight controllers are all taking one last look through their data getting ready to report polling status while Bob walks Val through a final suit integrity check & switch over to internal life support, which Bill said he felt rushed doing later in the count
Kerbal Space Agency
@KSA_MissionCtrl
[L-13m] late onload of pressurized nitrogen gas for the fuel tanks has begun to be transferred from the one tanker truck hooked up on the pad before close outs. This protects workers from any rupture
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] pad is clear, launch corridor is clear, airspace empty - RSO has closed the range, Flight Termination System/LES is ACTIVE, rocket is ARMED. All visitors should be wearing hearing protection - security will perform a check & anyone not will be moved indoors
Kerbal Space Agency
@KSA_MissionCtrl
there was an extended period of grunting, scraping and bumping noises coming over the capsule comms. When they died down Bob asked - "what was all that?" Val, embarrassed she forgot to mute her mic, replied - "I was scratching an itch on my head"
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] final countdown has begun, meaning from this point on any issues will likely result in a reset to L-30 with a new L-0. Local weather conditions and conditions at the recovery site remain green. Pad workers prepping to clear the launch site
Kerbal Space Agency
@KSA_MissionCtrl
[L-45m] all systems are set and assets in place for the launch team and Val to run a full ascent simulation to make double sure all is ready and usually as a final exercise since FD Lanalye can throw in some curve balls. Launch countdown intensifies...
Kerbal Space Agency
@KSA_MissionCtrl
Bob & Val are very close friends, so having him to chat with during this late stage in preflight has kept her relaxed when she doesn't have much to do & anxiety can creep in. Still, Flight Surgeon is keeping a close eye on her vitals even when down here on the ground
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h20m] balloon has been deployed off the rear MSV deck to rise over 18km and give us readings on wind conditions, including any shear that could present a danger to the ascent. It will reach the upper atmosphere just prior to L-5min polls
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h30m] issues board is clear as preflight wraps up! FD Lanalye confirms the rocket is ready, now comes final external setup work as the pad is closed out, MSV Lymun offshore takes status of the launch corridor with the Range Safety Officer, weather balloon preps for release
Kerbal Space Agency
@KSA_MissionCtrl
you are NOT allowed to drive personal vehicles across the causeway! Park in the Support Village garage and wait for a shuttle bus. Security just cleared another traffic jam because we had to make a car turn around at the gate. Don't hold up other launch attendees!
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h55m] issues board has cleared up nearing the end of preflight, engine systems are now being checked after the pad crew clears out except for the Quick Response Team sheltering in the nearby bunker. Most of Val's work in the capsule prior to launch has been completed
Kerbal Space Agency
@KSA_MissionCtrl
the Ascension Mk1 can be flown with an empty capsule - so what does the crew have to do? The control panel still needs manual configuration for flight, readouts have to be visually checked, manual controls need to be manipulated to ensure proper function.... plenty!
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h40m] tanking completed on schedule, pad workers getting fuel equipment tidied up while flight controllers continue preflight, keeping Val busy so she's not thinking about the 7t of explosive liquid she's now sitting atop of. Launch Escape System has been armed
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h55m] Monolith chilldown was begun earlier today and weather desk reports atmospheric pressure is stable. Rocket is configured for tanking and pad crew has the fuel truck hooked to the service towers. GO has been given to begin propellant onload
Kerbal Space Agency
@KSA_MissionCtrl
no major changes to the Automated Flight Control System from the last launch, just some tweaks to the operational code, the details of which you can check out here: bit.ly/AFCS_ChangeLog
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h10m] mounting was wrapped up during flight briefing, weather remains GO with new launch forecast showing no adverse surface conditions. Bob is back at Launch Control for his CapCom duties, walking Val through capsule configuration with the launch team
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h40m] Flight Director Lanalye has her A Team assembled in Launch Control for final mission brief. If the rocket manages to stay on course and fly the planned trajectory Val should have nearly 13 minutes in space, more than twice as long as Bill's 0G trip
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h10m] conditions outside at KSC are great as we approach second sunset, weather kerbs are taking stock of the day cycle's meteorological data from regional weather stations, airships and maritime vessels to work up a new launch forecast
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h20m] capsule hatch has been sealed, loading ramp moved away and Bob has his intercom plugged in to keep tabs on Val inside as mounting operations begin to get the rocket back to vertical atop its engine mount and hooked into the service tower
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h45m] capsule is prepped for ingress and Val is climbing in, assisted by Bob and pad workers as the angle makes getting in easy but strapping in is a bit more of a challenge while wanting to roll sideways. Crew photo snapped earlier after arriving at the pad
Kerbal Space Agency
@KSA_MissionCtrl
[L-5h] Cdr Val has climbed aboard the crew shuttle to depart for the launch pad, the rocket was lowered without issue. Expect updates from us at these major milestones as the countdown to launch progresses
Kerbal Space Agency
@KSA_MissionCtrl
our recovery vessel MSV Aldeny left port yesterday to sail out to the recovery zone. They have checked in to report choppy seas but not enough to endanger recovery of the capsule after splashdown. They will continue to report conditions up until final launch polls

@KSA_MissionCtrl
Val & Jeb are both awake (well, in Jeb's case woken up) and enjoying their choice breakfasts prior to suiting up. Val will depart for the pad at L-5hrs while Jeb remains in the ready room in the event that he is needed to crew the capsule
Kerbal Space Agency
@KSA_MissionCtrl
it's an early start for pad workers, who are heading out now just prior to sunrise so the rocket can be lowered off its engine mount and back onto the carry vehicle in preparation for crew loading later this day cycle
Kerbal Space Agency
@KSA_MissionCtrl
final medical checkup for our crew shows they are both ready for flight, Ops Dir @DKerman_KSA has signed off on them and the rocket - we are officially 🚀 GO FOR LAUNCH! 🚀 90% good forecast w/chance of surface winds. Pre-launch ops will kick off @ 12:10 UTC
Kerbal Space Agency
@KSA_MissionCtrl
our 1st kerbed launch had the rocket rolled out the same day so we wouldn't have to lower it again. However we ended up doing that anyways a few times & the pad crew found it to not be as big a hassle as feared, so now it is rolled out a day prior & can undergo extra checks
Kerbal Space Agency
@KSA_MissionCtrl
the Ascension Mk1 had a good roll out and mounting over the previous day cycle. Flight Director Lanalye and her A team are preparing for a wet dress rehearsal to make sure all connections and pad equipment are ready for operations as part of their launch readiness
Kerbal Space Agency
@KSA_MissionCtrl
Val, primary crew, is spending most of her time while cooped up reviewing her mission materials. Jeb, backup crew, is pretty much gaming until he passes out. Had their roles been reversed... they would both most likely be doing the same thing
Kerbal Space Agency
@KSA_MissionCtrl
wrap it up folks, weekend is here! Get caught up on all our operations this past week with additional details via our Ops Summary: kerbalspace.agency/?p=9767 it's been mostly crummy weather all week so let's all hope for a turn-around this weekend
Kerbal Space Agency
@KSA_MissionCtrl
final closeouts passed, loaded up on its carry vehicle and marshaled to the front of the VAB, Commander Val's ride to space is now ready to head for the pad next week! Jeb has been trying to convince everyone he's hearing lots of coughing coming from her quarters
Kerbal Space Agency
@KSA_MissionCtrl
🎊✨Happy Operational Birthday to us!✨🎊 KERZZAH!
today is the start of our 4th year in operation 🥂 Send us a gift - tell us what you enjoy most about the Kerbal Space Agency.

@KSA_MissionCtrl
load checks passed, structural elements all good, the Ascension Mk1 was laid back horizontal in the VAB today then gone over with a fine-toothed comb (AKA 26 page checklist) to make sure everything was completed as planned during its construction. They'll finish tomorrow
Kerbal Space Agency
@KSA_MissionCtrl
daily medical checkups for our crew in quarantine ensure not only that they remain in good health but also allow physicians to collect base line data they can then use after the astronaut returns to see what effects exposure to 0G might have on the body, even for a short time
Kerbal Space Agency
@KSA_MissionCtrl
TL;DR: we learned a lot of new lessons, some of which have already been applied to Val's upcoming mission for what we hope will continue to be progress towards a more on-target ascent & final trajectory so our future missions can save fuel & fly tighter margins
Kerbal Space Agency
@KSA_MissionCtrl
all the nitty gritty details on last month's Ascension Mk1 flight are now available along with a full data and performance analysis from the rocket telemetry. Want to know what these plots are all about? Check out the report: kerbalspace.agency/?p=9754
Kerbal Space Agency
@KSA_MissionCtrl
Commander Val & Captain Jeb are now sequestered within the Astronaut Complex until next week's mission. They'll be regularly monitored & only accessed by medical staff to ensure both are & remain in good health. Bill & Bob are totally not planning to lounge outside their windows
Kerbal Space Agency
@KSA_MissionCtrl
with the previous Ascension flight analysis wrapping up & data from the rocket sled testing, planners have made a late change to next week's mission w/ a higher trajectory from ensuring the rocket burns out w/in the atmosphere, nearing 300km apokee & slightly rougher on re-entry
Kerbal Space Agency
@KSA_MissionCtrl
the purchase of flight hardware for two more Ascension Mk1 rockets has been ordered. Whether one of them will be used to build a Mk2 depends on the success of the mission in October. We could possibly fly a second Mk2 in Dec before operations cease for the year
Kerbal Space Agency
@KSA_MissionCtrl
this behavior has been evident the past 4 flights since we started angling the fins, but it has always been masked by another more obvious issue and we never saw it happen on its own until the rocket burned out of the atmosphere with a stable attitude
Kerbal Space Agency
@KSA_MissionCtrl
ongoing analysis shows what happened at the end of last mission's ascent. The fin angle offset mass to create torque downwards and to the left (right fin is rocket bottom) when near empty tanks . Window on left shows that even had we used RCS thrusters this could not be overcome
Kerbal Space Agency
@KSA_MissionCtrl
Jeb managed to just barely beat Val 434 successful missions to 431 (total) in their last day of capsule simulator training. There's undoubtedly still things that can go wrong we haven't thought of to prepare for but hopefully that list is very, very small
Kerbal Space Agency
@KSA_MissionCtrl
we had a successful static fire of the K2-X engine today on the test stand after the ignition system was repaired. The engine will now head back to the VAB to be refurbished and readied for integration with its flight fuel tank late next week
Kerbal Space Agency
@KSA_MissionCtrl
next week's Ascension Mk1 has gone vertical for capsule integration and load checks in the VAB over this week, after which it will be laid back horizontal for final closeouts and loading up onto the carry vehicle for rollout next Monday
Kerbal Space Agency
@KSA_MissionCtrl
Val and Jeb have both been released this weekend to head home and spend time with their friends and families before the intensive week leading up to the mission begins. Jeb hails from Ockr and Val was born in Kravass
Kerbal Space Agency
@KSA_MissionCtrl
learn more details on what went on this past week in our Ops Summary: kerbalspace.agency/?p=9624 Everyone have a relaxing weekend! We look forward as always to greeting all the visitors that will be stopping by - be sure to check out the new Ascension Mk1 static display!
Kerbal Space Agency
@KSA_MissionCtrl
the newest K2-X engine was mounted to the test stand yesterday and today attempted a static fire test but failed to ignite. Engineers suspect it is just a relatively simple igniter issue and hope to have it fixed and ready to try again next week
Kerbal Space Agency
@KSA_MissionCtrl
the great part about the check is it's very simple - if the control movements do not cease by the time of ignition at T-6s, then it's because they are moving too slowly through the planned motions due to lack of hydraulic pressure and engine ignition will be aborted
Kerbal Space Agency
@KSA_MissionCtrl
here's a close-up look of the engine ignition from the last Ascension Mk1 flight, with the new control movement sequence. This was added to double-check hydraulic performance in the event that readouts from the rocket to controllers on system pressure were incorrect
Kerbal Space Agency
@KSA_MissionCtrl
Lead Engineer Simon has told the Ascension team to expect delays to the Mobile Launch Platform as they struggle with getting the engines installed. They still hope to finish by the end of the month but could possibly run into early October
Kerbal Space Agency
@KSA_MissionCtrl
the Kongo River Research Station has its own 500km communications aerial for local transmissions. A ground/sea cable connecting it to Kravass is being proposed for next year, but until then any orbiting satellite that sends down data to the station can't get to us directly
Kerbal Space Agency
@KSA_MissionCtrl
obviously none of our astronauts like to "die" in the simulator, but if they never did then they wouldn't be training hard. Jeb says FD Lanalye must have some kind of hidden sadistic personality to manage to come up with so many ways to try to kill them
Kerbal Space Agency
@KSA_MissionCtrl
VAB is quite busy these days with this month's Ascension Mk1 center stage for final integration prep, next month's Ascension Mk2 is starting to get some attention and the Progeny Mk7-A for later this month is almost ready for staging. Guest appearance by the rocket sled
Kerbal Space Agency
@KSA_MissionCtrl
many continued thanks to our bit.ly/KSA_Patreon donors for getting us into the green this past month! August financial report is available here: docs.google.com/spreadsheets/d… we expect to see narrow margins for the remainder of the year
Kerbal Space Agency
@KSA_MissionCtrl
the 1st K2-X engine ordered back in May has been delivered, one of three that will be completed by the end of the year. This one is earmarked for the 1st Ascension Mk2 mission & will be test-fired this week to ensure good operation prior to integration with its flight hardware
Kerbal Space Agency
@KSA_MissionCtrl
the capsule from last week's flight has been delivered back to KSC so it can begin to be closely inspected by engineers in the VAB to determine how it and its various accompanying parts are holding up after multiple flights, which will ultimately affect kerbed capsule reuse
Kerbal Space Agency
@KSA_MissionCtrl
the Extremis program is still being granted processing time to work possible future trajectories for beyond 2021 and we are still hoping to launch the first Extremis probe to fly by Eve, Jool and Plock in 2021 over the course of just 3 years!
Kerbal Space Agency
@KSA_MissionCtrl
today was supposed to be the launch of Extremis 2, aiming to fly by Moho, Duna, Dres and Jool. While it may seem laughable now to think back in 2017 we imagined we'd have interplanetary space craft capabilities by now, there was never any reason to hold back on our ambitions
Kerbal Space Agency
@KSA_MissionCtrl
final full week of mission training for Val and her backup Jeb will consist of many capsule simulator sessions along with physical exercise and evaluations. Bill and Bob have the lighter but still intense workload training with the A team of mission controllers
Kerbal Space Agency
@KSA_MissionCtrl
leaving August behind and pushing forward into September! Check out all the exciting stuff that happened this past week in our Ops Summary and have yourself a pleasant weekend everyone! kerbalspace.agency/?p=9606
Kerbal Space Agency
@KSA_MissionCtrl
the Ascension Mk1 mockup joins the Progeny Mk4 (first in space) out on our campus lawn. This weekend a special dedication ceremony will be held and the Presider will be on hand to award Specialist Bill a commendation medal for being the first kerbal in space
Kerbal Space Agency
@KSA_MissionCtrl
the Mobile Launch Platform construction continues on schedule in the HAB. One of the two massive engines is being placed today for installation next week, followed by the second the week after and the treads will be attached to the transmission blocks by mid-Sept as well
Kerbal Space Agency
@KSA_MissionCtrl
because we never developed the technology before being forced underground and after that there was no reason for anyone to pursue it. Second to last paragraph has more details: kerbalspace.agency/?p=4451
Kerbal Space Agency
@KSA_MissionCtrl
this mission will also be the operational debut of the cold gas engine we spoke about earlier this year. It is a great choice for future long-term missions that only need to maintain their orbit as it is simple and thus very reliable twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
the RTG is another test article like the one that will be flown on the Progeny Mk7-A to further check the ability of the casing to withstand re-entry and impact - possibly the first test if the Mk7-A mission fails again. We plan for the RTG to be flight certified by mid-2020
Kerbal Space Agency
@KSA_MissionCtrl
Kerbin I plans are finalized! Our 1st orbital probe is based on future communication satellites that will be among the 1st commercial payloads for the Ascension Mk2. It has enough battery to last 18-20 hrs on orbit & can also hibernate if needed. Full res: flickr.com/gp/kerbal_spac…
Kerbal Space Agency
@KSA_MissionCtrl
because the lift stage w/booster cam remained attached, because the rocket was slowly tumbling and because there was a little bit of extra storage, we managed to snag these three photos in sequence from 327km apokee staring down towards Sheltered Rock and Ockr
Kerbal Space Agency
@KSA_MissionCtrl
while the capsule is still waiting to be shipped back to KSC, the data onboard has already been extracted and transmitted to us. Here is the final operations log from yesterday and the full telemetry data is available here: docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
MSV Aldeny has the capsule aboard and is setting sail back for Ockr, where it will be loaded up on one of our regular supply shipments - which saves more cost but means that sometimes it can take a few days to arrive back at the Cape. In this case it will return early next week
Kerbal Space Agency
@KSA_MissionCtrl
post-launch operations have concluded, pad remains in good shape for next month's mission. Technically, this was the 51st launch overall if you count the air launch of the Mk1-B last year (kerbalspace.agency/?p=8264) but we are marking today's launch as the 50th from the ground
Kerbal Space Agency
@KSA_MissionCtrl
MSV Aldeny is still about 40min out but has confirmed they've picked up the locator beacon from the capsule! 🎊 KERZZAH! 🥂 its main batteries will have drained by now so the remainder of the operations log will be included with the flight telemetry tomorrow
Kerbal Space Agency
@KSA_MissionCtrl
unfortunately due to the off-course trajectory we have lost the capsule below the horizon before we could get confirmation of full chute deployment, but all telemetry until LOS looked good and MSV Aldeny is only just over an hour from the splashdown location. Standing by...
Kerbal Space Agency
@KSA_MissionCtrl
capsule was still orienting retrograde upon atmospheric entry and saw some minor AoA wobble but remained pointed in the right direction. We are through comm blackout & have confirmation terminal velocity slowed the capsule enough to dump the LES for initial chute deployment
Kerbal Space Agency
@KSA_MissionCtrl
<10s to atmosphere, good capsule sep followed by a radial orientation and then guidance was unlocked for a manual forward thrust to put more distance between the capsule & lift stage before re-orienting retrograde to present the heat shield towards the velocity vector
Kerbal Space Agency
@KSA_MissionCtrl
passing down through 250km controllers are preparing to stow the GRS and then separate the capsule from the lift stage. The rocket is in a slow end-over-end tumble (~0.5RPM), so it's important to wait for the proper moment to ensure good initial separation
Kerbal Space Agency
@KSA_MissionCtrl
through 327km apokee now, the RPWS has been stowed and the Gamma-Ray Spectrometer is now rotated to face out the capsule hatch and has been deployed. It will gather readings through the coast down to low-Kerbin space at 250km before we run short of data storage capacity
Kerbal Space Agency
@KSA_MissionCtrl
we're having issues with high-rate data transmission & will have to forsake some of our planned scientific observations on this mission since we cannot store all the data meant to xmit. New trajectory has been confirmed & MSV Aldeny is moving off station to the new recovery area
Kerbal Space Agency
@KSA_MissionCtrl
magnetometer on the fuel tank has been extended and the capsule hatch has been opened to deploy the RPWS antenna. Principle investigators are receiving science instrument data downlink while mission planners continue to evaluate the new trajectory
Kerbal Space Agency
@KSA_MissionCtrl
MECO @ 104km, a little higher than planned 98km and also now well off course due to an off-center thrust of the rocket that became apparent as it continued to burn out of the atmosphere w/o any ctrl surfaces to fight against it. Controllers are assessing the situation
Kerbal Space Agency
@KSA_MissionCtrl
ascent continues to look good into the upper atmosphere, as seen visually from the ground tracking cam. Telemetry-wise all remains nominal as well, apokee is out of the atmosphere and guidance remains on course heading 53°, now holding 44° pitch for the remainder of the ascent
Kerbal Space Agency
@KSA_MissionCtrl
rocket is supersonic and through MaxQ, throttling back to maintain a TWR of 2.5 & ensure science instruments are not damaged by excessive force or vibration. Guidance had the usual early ascent problems for pitch & heading but is back on course, engine parameters remain nominal
Kerbal Space Agency
@KSA_MissionCtrl
good main engine start, throttle up and
✨50th LIFT OFF✨
The 8th Ascension Mk1 takes to the sky, carrying new scientific instruments up into space! Clearing the tower, the rocket will roll onto launch heading and then begin to pitch downrange as it throttles up to full power

[T-1m] time to tune in to ops.kerbalspace.agency if you have not already for live launch telemetry! Final poll at T-30s followed by these events leading up to launch. We added a new check to ensure hydraulics remain nominal
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] terminal count has begun with the AFCS taking control of the rocket as the service arm swings away. Rocket is already switched over to battery power and drain rates are being monitored while RF comm check is underway
Kerbal Space Agency
@KSA_MissionCtrl
[L-3m] prior to service arm retraction in the next minute, tank pressurization has begun to add rigidity and allow the rocket to stand alone upon the engine clamp. Without it, a strong wind could literally crumple the rocket & collapse it onto the pad. Likely w/ a giant explosion
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] Final readiness polls complete: Wx: GO; Range: GO; Flight: GO; Tracking Station: GO; Downrange Tracking: GO; Ops Director @DKerman_KSA: Launch permission granted! 🚀GO ASCENSION🚀 FTS power internal, service tower booms unlocked for retraction, AFCS rdy for terminal count
Kerbal Space Agency
@KSA_MissionCtrl
[L-13m] the lone tanker truck still hooked up to the service towers has been commanded remotely to begin onload of pressurized nitrogen gas that will help ensure rigidity & fuel flow in the rocket tanks. Late onload keeps pad workers safe from any tank ruptures
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] range closure is in effect, any incursion will hold the count. Rocket has been ARMED, Flight Termination System/LES is ACTIVE. Reminder to all visitors that hearing protection is REQUIRED outdoors - we've only had to escort offsite 2 kerbs so far since 2018
Kerbal Space Agency
@KSA_MissionCtrl
off to the right in the previous photo are 4 celestial bodies. Who can name them? We'll give you Minmus, up top, since that's tough to determine from a photo. The other three? Maybe checking out the current planetary locations will help bit.ly/Ops_Tracker

@KSA_MissionCtrl
[L-30m] we are GO for final countdown! Weather has been improving all day both here & over recovery zone so now just hoping for a report of calm @upperlevelwinds at L-5min. Range Safety Officer is awaiting confirmation of pad lock-down and clear air/sea range
Kerbal Space Agency
@KSA_MissionCtrl
[L-45m] inside an hour to launch, pad crew is preparing to clear out and FD Lanalye is running her team through a rehearsal to ensure all systems and assets are properly setup for the mission while the weather desk takes another look (literally) at conditions outside
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h20m] weather balloon has been released from outside the VAB, it will ascend into the upper atmosphere (+18km) by the time we near L-5min general polls to give us an idea of upper-level wind conditions that could potentially pose a threat to the ascent
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h30m] FD Lanalye reports the rocket is all checked out & ready to go! External tasks now the focus - getting the range setup with MSV Hoodall on station for monitoring, closing out the launch pad for final evacuation and prepping to release the weather balloon
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h55m] the majority of preflight has concluded and the issues board remains clear. Pad is secure & being evacuated ahead of engine systems/ignition checks while a Quick-Response Team shelters in the nearby bunker
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h40m] tanking has wrapped up on schedule, filling the liquid fuel and oxidizer tanks to the top with a combined 7t of propellant. Pad crew now cleaning up from fueling operations while controllers maintain vigilance on fuel levels to ensure no leaks are present
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h55m] rocket is woke, systems initialized and pad crew has the tanker hooked up to the service tower - FD Lanalye says we are GO for fueling operations. Photo taken a few minutes ago as the light from sunset fades behind the mountains
Kerbal Space Agency
@KSA_MissionCtrl
the base Automated Flight Control System has some new default atmospheric logging data while operational code changes have been made to suit the mission profile, all of which can be reviewed here bit.ly/AFCS_Changes
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h10m] we are GO from the weather desk to continue into pre-flight, although conditions remain iffy. Monolith temple is cleared out for general safety but no longer chilled down for unkerbed missions. Controllers are on console waking up the rocket & onloading flight software
Kerbal Space Agency
@KSA_MissionCtrl
we also wanted to try some additional emergency recovery procedures during the return using the LES but it's important we get the onboard instruments back safely, which is also why this mission has a Launch Escape System included to begin with
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h40m] Flight Director (FD) Lanalye is gathering her B team in Launch Control for final mission briefing. Here is an overview of the flight, which will be less-aggressive on ascent than previous unkerbed missions due to the sensitive scientific instruments onboard & outboard
Kerbal Space Agency
@KSA_MissionCtrl
RT @DKerman_KSA: there is no launch time constraint for this mission. Making the early attempt just means if anything goes wrong in the lead-up there's a better chance we can make at least another attempt before scrubbing the day.
This logic however does not make getting up before 7am easier -_-

sea conditions are finally calming down east of Ockr and MSV Aldeny was able to move back into recovery position. Launch forecast for tomorrow not as good with 30% chance of violation but that's enough to commit to pre-launch operations, which will kick off at 11:25 UTC
Kerbal Space Agency
@KSA_MissionCtrl
launch has been scrubbed for today. MSV Aldeny was forced earlier to move off station as conditions worsened and has not been able to return. We will continue to monitor the situation and do not expect conditions to persist into tomorrow. New L-0 set for 15:35 UTC on 8/28
Kerbal Space Agency

@KSA_MissionCtrl
Ascension Mk1 for next week has passed load checks and is being laid back horizontal for final close outs. Mk1 for Sept has its engine prepared and will be center-stage next week to begin its final integration while the Ascension Mk2 & Progeny Mk7-A prep begins in the wings
Kerbal Space Agency
@KSA_MissionCtrl
Ascension Mk2 mission was running a fine line between test vs. success - we want to push the rocket to its limits but also want to see it succeed making orbit. Ultimately Ops Director @DKerman_KSA has lowered the payload mass from 2t to 0.5-1t for more comfortable error margins
Kerbal Space Agency
@KSA_MissionCtrl
the ascent profile for the upcoming unkerbed Ascension Mk1 mission was easy to plan because the mass of the rocket ended up within 200kg the mass of the last mission thx to the lighter fins & control surfaces. Sometimes, things just work out
Kerbal Space Agency
@KSA_MissionCtrl
the heat shield from the last Ascension flight came back with 197u of ablator and after resurfacing still has 180u remaining. This implies It could be reused several more times but its not just the surface that we need to worry about, also structure from repeated High-G stress
Kerbal Space Agency
@KSA_MissionCtrl
order has been put in with NovaPunch for 3 more K2-X lifter engines for delivery at the start of 2020. Contract bidding has already begun for our next lifter engine, which should begin testing Q2 2020. Will likely just replace the K2-X, not used for an Ascension Mk3

after almost a year of R&D, Wernher has just announced his team had a breakthrough with Monolith crystal, getting stable energy storage without any heat radiation. Now they just have to figure out how to slowly release the energy without the crystal blowing up violently
Kerbal Space Agency
@KSA_MissionCtrl
scientists continue to remain fascinated by the ability of the Goo to resist space radiation, different from the radiation of its underground habitat, and also enter stasis when lacking atmosphere. Longer-term orbital studies are needed to fully understand it
Kerbal Space Agency
@KSA_MissionCtrl
papers have been hitting science journals with results from the Mystery Goo atmospheric flights in 2018 and space flight early this year and now new orbital experiments are being designed that we hope to have the privilege to fly in early 2020 aboard the Ascension Mk2
Kerbal Space Agency
@KSA_MissionCtrl
Ascension team has mostly locked in the mission profiles for the next two flights and are now focusing on the Mk2 mission, which will aim to put a 2t payload into low-Kerbin orbit - basically the heavier a mass we can throw up the more power & longer life it will have up there

Lead Engineer Simon & Head of R&D Wernher von Kerman still haven't agreed on who to blame for misreading or mislabeling the dimensions of the folded magnetometer boom but it won't fit in the capsule. Slim profile however means it can be mounted externally on the fuel tank

Bill spent time with the capsule simulator team today planning some changes to make the experience feel more authentic now that he knows what the differences are between simulated and actual space flight - such as not being able to get audio feedback of the thrusters firing

@KSA_MissionCtrl
the vertical test stand today had a good static fire of the K2-X engine that will power the next unkerbed Mk1 rocket into space. Before the kerbed Mk1 engine gets its turn, we will make sure dampeners functioned properly to keep the fuel tank from damaging the engine again
Kerbal Space Agency
@KSA_MissionCtrl
CFO Mortimer is looking into the potential for recovering the SRBs from the Ascension Mk2 since they will be let go at 2-3km and land close enough our range vessel could perhaps recover them for little extra cost. Core lifter though is not recoverable for less than a new one

last week's Viklun stage test also put the CX-4181 control system through its paces. It has two CPUs for redundancy and cross-check during ascent and orbital insertion, then allows the stage to perform maneuvers after payload separation

our new test stands have been completed to replace the one destroyed by an engine explosion back in Feb. Vertical stand will test liquid engines & horizontal stand will test SRBs - both up to 3.75m. The K2-X engine for the next Ascension Mk1 flight will be mounted this week
Kerbal Space Agency
@KSA_MissionCtrl
results from the Viklun test firings show it is likely to under-perform in flight, due to losses in efficiency while operating. This is not unexpected for our first vacuum engine design. Further modeling of Mk2 Mun/Minmus missions has been put on hold until we have flight data
Kerbal Space Agency
@KSA_MissionCtrl
the unkerbed Mk1 & Mk2 missions will use the newer, lighter fins & ctrl surfaces. Kerbed Mk1 will stick to originals not just because they are well-tested but the same mass makes it easier for flight planners to stick to the same trajectory we wanted for the 1st kerbed mission

flight analysis for the kerbed Ascension Mk1 mission last month has been posted: kerbalspace.agency/?p=9491 Ascension team is now working to schedule the next two missions - expect dates to be announced later this week
Kerbal Space Agency
@KSA_MissionCtrl
the Ascension Mk2 is configured with 4 SRBs by default but costs could be saved by launching with less. All 4 provide important structural loading though while on the MLP, so in cases where fewer can be used, dummy boosters will be left behind on the pad at launch
Kerbal Space Agency
@KSA_MissionCtrl
our gains in July are thanks solely to our success in putting a kerbal in space. Now we have to again stave off bankruptcy with a successful orbital insertion later this year, an endeavor the majority of our remaining funds are dedicated to. No pressure! docs.google.com/spreadsheets/d…

Ascension team have given the GO for tomorrow's second restart/third firing of the Viklun orbital stage after finding no serious issues in the data from the test burns earlier this week
Kerbal Space Agency
@KSA_MissionCtrl
have a look at the frequency of our missions over the past few years broken down by program. This is just one of many examples of data visualization we've published in the past. You can see more in our flickr album: flickr.com/photos/kerbal_…
Kerbal Space Agency
@KSA_MissionCtrl
second engine burn was successful! Viklun can be restarted twice, so another test on 8/2 will go for the third ignition after time is taken for data analysis and engine inspection while the stage remains out on the pad
Kerbal Space Agency
@KSA_MissionCtrl
we have a GO from the Ascension engineers to re-light the engine at 10% thrust, which is a test in itself since we've never restarted an engine before. If ignition is good, engine will throttle up to full and remain wide open until flame out. 15min to test start
Kerbal Space Agency
@KSA_MissionCtrl
and we have cut-off as planned with 9.8% fuel remaining after a good burn of 1m37s! Controllers will hold while Ascension team takes a look at the data & if everything checks out we will perform an engine restart to burn through the remainder of propellants
Kerbal Space Agency
@KSA_MissionCtrl
good engine start, burn will last over the next ~2min. The two unoccupied tanker trucks are carrying water that will be activated shortly to douse the pad & keep the surface from overheating from the continuous rocket exhaust. Vertical mount ensures proper fuel flow to engine
Kerbal Space Agency
@KSA_MissionCtrl
🚨AAAHHWWWWOOOOOOOOO🚨
5min warning horn sounding across KSC as ignition system goes hot. Pad is cleared, no Flight Termination System is enabled - TWR @ sea level is less than 1 so if engine vibrations compromise ground clamps for some reason the stage would just fall to the pad

@KSA_MissionCtrl
standing by for leak checks and pad closeouts, we are aiming for an ignition time of 22:00 UTC. First of two ignitions will be at full thrust to simulate the initial push into orbit, with throttle tests at 30% fuel remaining and cutoff at 10% fuel remaining
Kerbal Space Agency
@KSA_MissionCtrl
tanking completed, onloading 2t of liquid propellants to power the vacuum engine. Because we are testing it in atmosphere performance will be reduced but that can be compensated for in post-analysis and also really for basic testing we just want to make sure it doesn't blow up
Kerbal Space Agency
@KSA_MissionCtrl
mounting was good, launch control now getting the onboard controller initialized and ready for tanking. Viklun has its own computer so once a payload is detached it can still be de-orbited or moved to a graveyard orbit, orienting via its own cold gas thrusters (no engine gimbal)
Kerbal Space Agency
@KSA_MissionCtrl
@StronkTenk_ The plan was to have one in orbit already but the Ascension Mk1 turned out to not be capable so we have to wait for the Mk2 so probably early 2020 assuming it can put a payload into orbit by the end of this year
Kerbal Space Agency
@KSA_MissionCtrl
the Viklun orbital stage that will make up part of the Ascension Mk2 is on its way out to the launch pad for mounting, where it will be static-fired prior to 4th sunset. This will be the 1st firing of the actual production engine as well as operation of the whole integrated stage
Kerbal Space Agency
@KSA_MissionCtrl
we have a new rocket component that needs to be checked out, and will undergo testing tomorrow. Okay who's been keeping track of things out there and can tell us what's being sent out to the pad? The parts were ordered back in April
Kerbal Space Agency
@KSA_MissionCtrl
the capsule that flew 2 unkerbed missions will continue to fly & show how they wear over time. No longer needed for testing crew systems, its main hatch is being modified to be opened & closed in space. The ECLSS will be removed for more room to hold experiments & instruments
Kerbal Space Agency
@KSA_MissionCtrl
we've finally sent a kerbal up into space. Here is a timeline overview of the rockets that it took to get us to this point. The next big step is to reach orbit, altho whether that will be with a probe or a capsule still has not yet been decided. Full res: flickr.com/gp/kerbal_spac…
Kerbal Space Agency
@KSA_MissionCtrl
the Mobile Launch Platform we revealed back in May now has the funding to begin construction. Since the HAB has no current Genesis/C7 projects, it will host the build. The MLP is expected to be ready by late Sept, so an Ascension Mk2 launch will be no sooner than that
Kerbal Space Agency
@KSA_MissionCtrl
our next big milestone is coming up with the next launch being our 50th rocket mission! So close to combining that with 1st space flight but at the same time happy to let it have its own recognition. Unsure yet which flight will be 50th - Val's Mk1 or unkerbed Mk1

the capsule that carried Bill to and from space has arrived back at KSC via airship along with its heat shield. The Air History Museum in Kravass is already trying to buy it from us, but we need to do a complete post-flight examination of it first over the next week
Kerbal Space Agency
@KSA_MissionCtrl
Specialist Bill's full physical examination has been completed with no obvious signs of problems from his short jaunt through space, but doctors still wary and will be going over the data closely before clearing Val for the next flight. Bill will be back at KSC tomorrow
Kerbal Space Agency
@KSA_MissionCtrl
the award will also enable us to send Val, next in rotation, to space no earlier than Sept while also sending up another unkerbed Mk1 w/ the older capsule for more testing of Extremis instruments. Not enough tho for another Progeny Mk7-A flight unless KB/Genesis can help w/income

@KSA_MissionCtrl
now that MSV Aldeny is berthed in Sheltered Rock & doesn't have to travel from Umbarg to the recovery area off Ockr, w/o long delays requiring resupply we should have cheaper mission costs. This past mission ran up a bill slightly greater than the usual 6,200 funds MSV rental
Kerbal Space Agency
@KSA_MissionCtrl
MSV Aldeny has arrived at Sheltered Rock, where Specialist Bill will undergo a full medical evaluation to assess his body's reaction to the brief space flight before returning to KSC this weekend. He maintains feeling no ill effects since the mission
Kerbal Space Agency
@KSA_MissionCtrl
although he was very busy during his short flight through space thanks to the pitch anomaly, Mission Control did tell Bill when he was passing over the site of our first future surface colony and he was able to stick the camera up to the window for a shot. North is left

@KSA_MissionCtrl
still excited by yesterday's success, rocketry teams are eager to start analyzing the latest Ascension Mk1 flight, especially to see why it flew so shallow on ascent & nearly endangered the mission. Here is the telemetry data: docs.google.com/spreadsheets/d…

@KSA_MissionCtrl
Bill managed to stay put until the capsule was hauled out of the water. He's back on his feet aboard MSV Aldeny & will shortly set sail for Sheltered Rock, where they will arrive late tomorrow. Everyone here is ready to party the rest of the day away. Celebration time! Ah yea! 🥂

post-launch operations well underway here @ KSC, pad crew inspecting for any damage while controllers perform initial post-flight analysis to ensure all data is properly collected. Bill continues to float about; he can blow the hatch if capsule takes on water but landing was soft
Kerbal Space Agency
@KSA_MissionCtrl
🎉🎊 KERZZAAAAAH!! 🎊🎉 welcome back to our first space explorer! Cheers, hugs, high fours, backslaps - the control room has erupted in celebration after the capsule safely splashed down. Still in sight of Ockr relay, we can stay in touch with Bill until MSV Aldeny arrives
Kerbal Space Agency
@KSA_MissionCtrl
big grins all around the control room as Bill descends towards the water under a full canopy. He had to endure only just under 6Gs on re-entry. His new landing location puts him about 1.5 hours from MSV Aldeny, which had already gotten underway shortly after launch
Kerbal Space Agency
@KSA_MissionCtrl
"Control this is Ascension - copy you loud & clear! Heard my chutes pop, can you confirm?" Yes we can!! Chutes are pre-deployed & will stay reefed until lower in the atmosphere. Everyone happy & relieved to hear Bill's voice over the speakers. Let's bring him home!
Kerbal Space Agency
@KSA_MissionCtrl
still under blackout - static crackling through the comms piped into the mission control loud speakers. Could last over a minute with such a shallow re-entry. Jeb will shortly begin to call out for a response from Bill - "Control to Ascension, do you copy?" and we wait......
Kerbal Space Agency
@KSA_MissionCtrl
Bill had to override the computer turning off the RCS for re-entry so he could roll the capsule "up" to face away from Kerbin & begin re-entry butt-down. He will disable it again shortly for ballistic re-entry. Expecting plasma blackout any second now
Kerbal Space Agency
@KSA_MissionCtrl
coming up on atmo in <1min. Bill says all good tho noise of spacecraft louder than expected, a bit disorienting not being able to hear the thrusters firing like in the sim. He's positioned well tho & should see an even milder re-entry than originally planned, which isn't so bad
Kerbal Space Agency
@KSA_MissionCtrl
flight surgeon has been keeping a sharp eye on Bill's vitals & all still looks okay. Bill has been too busy to do much other than fly the capsule (tho he's caught some peeks out the window of course) but he's assured everyone as often as possible he feels no neg effects of zero-G
Kerbal Space Agency
@KSA_MissionCtrl
Bill has already passed thru 107.996km apokee. Trajectory analysis shows he should make the water, but even coming down over land he's on course and will miss any high terrain features. If needed the LES tower is still attached & can retrofire to slow final descent after re-entry
Kerbal Space Agency
@KSA_MissionCtrl
we had a clean capsule sep & pushaway. Bill has found guidance computer still locked into ascent mode & will not accept RCS orientation commands but manual controls responding fine so leaving computer alone. Capsule momentum flipped it retrograde & Bill is holding orientation
Kerbal Space Agency
@KSA_MissionCtrl
THERE'S A KERBAL IN SPAAAACE!!! However everyone is too focused on the unforeseen situation to really celebrate at this time - we still have to make sure Bill gets back down safely. We are currently monitoring the capsule separation & RCS thrusters pushing it clear of the lifter
Kerbal Space Agency
@KSA_MissionCtrl
31s left to MECO & although rocket pitch-over continues (from momentum not control surfaces) apokee is well outside atmo. Once engine cuts off the mad scramble will begin to determine how the shallow flight affects the downrange trajectory & what measures need to be taken
Kerbal Space Agency
@KSA_MissionCtrl
we have confirmed rocket is shallow on ascent. Pitchover increased shortly after L+1m & did not hold at 48°. Apokee still climbing & nearly into space with over a min left of burn. Danger of overheat in atmo negligible due to low throttle. Bill says "keeping calm & thrusting on!"
Kerbal Space Agency
@KSA_MissionCtrl
Bill is supersonic, through Max Q. Pitch-over rate is right on the money & on course heading 53°. Throttle decreasing steadily to maintain TWR of 1.65. Telemetry looks good & Bill is making regular callouts to assure everyone that what we're seeing is right. All nominal!
Kerbal Space Agency
@KSA_MissionCtrl
ignition sequence was nominal & WE 👏 HAVE 👏 LIFT OFF!! The first kerbed rocket is ascending to carry Specialist Bill up into the black void of space! Rocket will clear the tower in ~3 seconds and then begin to head downrange at nearly full throttle. GO ASCENSION! GO BILL!! 🚀✨

weather team still debating. Ops Director (OD) @DKerman_KSA has made it clear to them that if they aim to propose a launch at or near minimums they have to be 110% confident. What does Bill think of all this? He's asked Jeb if he can take a quick nap. The request was denied
Kerbal Space Agency
@KSA_MissionCtrl
[HOLD] L-5m final poll was not successful as the kerbs at the weather desk say they need more time to assess the upper-level wind conditions. While initial constraints are tight to ensure Bill's safety, we do have room to work the numbers based on past Ascension launch experience

the front stalled out and we have perfect launch weather right now around the previously-planned L-0. Hopefully future space satellites will help us improve models and better predict these weather events. Now we just have to hope tomorrow remains nice as well...
Kerbal Space Agency
@KSA_MissionCtrl
new forecast still shows only 40-50% chance of good weather. Hard to tell what an encroaching storm front from the west will do. They can sometimes power right over the mountains and bring down some serious weather on us. To be safe, launch is delayed until tomorrow @ 19:42 UTC
Kerbal Space Agency
@KSA_MissionCtrl

@KSA_MissionCtrl
all re-submitted readiness reports have been reviewed & approved - once again we are 🚀 GO FOR LAUNCH 🚀. However we'd like everyone to manage expectations as the current forecast is only 40% favorable. Launch ops will begin at 14:28 UTC if forecast improves
Kerbal Space Agency
@KSA_MissionCtrl
FD Lanalye is drilling her A team after ensuring they got rest over the weekend, Bill remains in good health, LE Simon has his crew doing an inspection of the rocket and Head of R&D Wernher von Kerman reports final tests are underway for the new Monolith direct-cooling system
Kerbal Space Agency
@KSA_MissionCtrl
in fact, there has been just as much opposition lately as in the past to what we are doing with the Monolith but violent outbreaks like this one back in 2017 have ceased since early 2018. We applaud religious leaders on their work to end such events twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
protesters have been gathered all weekend in the Support Village to picket against the further "desecration" of the Monolith. Extra security is still being deployed but so far all protests have remained peaceful here and in the caverns, where protests are happening as well
Kerbal Space Agency
@KSA_MissionCtrl
new Monolith direct cooling system has been rigged and Wernher's team have begun their testing to see whether or not it will work. We'll know for sure by the end of tomorrow when launch readiness reviews are submitted
Kerbal Space Agency
@KSA_MissionCtrl
MSV Aldeny has pulled into port at Sheltered Rock to resupply and then head back out tomorrow to once again sit and wait in the recovery zone. Hopefully we will be able to send a capsule their way soon!
Kerbal Space Agency
@KSA_MissionCtrl
for visitors this weekend bus tours will still take you out to the launch pad however they will not stop to allow occupants to disembark. You'll still get a drive around the pad perimeter though to get an up close look at the Ascension Mk1!
Kerbal Space Agency
@KSA_MissionCtrl
TL;DR - original theory of Monolith storm was because Mk6-II broke through the magnetosphere. However the next flight just happened to include kerbal tissue samples for exposure to space. Monolith must have thought we were launching a crewed mission, despite small samples
Kerbal Space Agency
@KSA_MissionCtrl
launch has been rescheduled to 7/23 @ 19:38 UTC while modifications are made over the weekend to the Monolith for even colder conditions. We also have a theory as to why it is behaving the way it is. Full details on our Ops Summary: kerbalspace.agency/?p=9352
Kerbal Space Agency
@KSA_MissionCtrl
we did another remote startup of the rocket at the end of the previous day cycle w/o Monolith chilldown & still saw no indications of stormy weather attempting to form. Lead Scientist Cheranne and R&D Lead Wernher von Kerman are working their teams overtime to reach a conclusion
Kerbal Space Agency
@KSA_MissionCtrl
the Presider's flotilla is on its way back to Sheltered Rock - he commended us on our procedures for handling the storm yesterday and regrets his busy schedule will not allow him to wait around for the next attempt though he will try to make it back when it happens
Kerbal Space Agency
@KSA_MissionCtrl
Bob has been released from quarantine protocol but Bill remains sequestered - if anything happens to him then it will further delay the launch at least a week while Val & Jeb train on the mission specifics to replace him as primary/backup, even if they start today
Kerbal Space Agency
@KSA_MissionCtrl
after some time to recover from his ordeal yesterday and think things over, Specialist Bob has ceded his spot to Specialist Bill. Bob says he's not ready to get back into that capsule anytime soon and will wait for his rotation to come back around
Kerbal Space Agency
@KSA_MissionCtrl
if you're not familiar with the Monolith storms, they came about earlier this year after we unintentionally sent a rocket outside the magnetosheath of Kerbin. You can learn more about them in this website article: kerbalspace.agency/?p=8594
Kerbal Space Agency
@KSA_MissionCtrl
still nothing. Nothing!? What is even going on here? We have a rocket powered up on the pad and no storms are forming, even with the Monolith temple heating back up to outside air temperatures. Until we can figure this out, launch remains delayed
Kerbal Space Agency
@KSA_MissionCtrl
rocket has been powered on for 20 minutes and weather desk is reporting no change to current conditions. Lead Scientist Cheranne has suggested that we switch off the Monolith A/C and see what happens. Everyone hold on to your butts...
Kerbal Space Agency
@KSA_MissionCtrl
rocket is remounted. Launch team will commence preflight at 22:00 UTC to give the atmosphere the entire day cycle to recharge from the sun's heat and ensure we can detect another attempt from the Monolith at forming a low-pressure system when the rocket is booted up
Kerbal Space Agency
@KSA_MissionCtrl
Specialist Bob is out and making his return to the Astronaut Complex for a medical evaluation while the pad crew continues their work to get the rocket back to vertical and re-attached to the service towers
Kerbal Space Agency
@KSA_MissionCtrl
weather conditions have improved enough to allow the pad crew to begin the unmounting operation. Rocket will be lowered, Bob will be extracted and then we are going to raise it back up and do an automated start later today to see what happens. Regardless, launch today is scrubbed
Kerbal Space Agency
@KSA_MissionCtrl
no lightning now for nearly 10 minutes and winds have continued to weaken. Val was the perfect person to help Bob calm down; he's been further assuaged by FD Lanalye saying the count will not be continued and the pad crew will be lowering the rocket soon and getting him out
Kerbal Space Agency
@KSA_MissionCtrl
doctors report Bob may be having a panic attack but he's not in any physical danger and pad crew should remain sheltered. Storm already appears to be weakening. Given that we've seen much worse prior to the Monolith A/C installation, good to know it seems to be helping somewhat
Kerbal Space Agency
@KSA_MissionCtrl
YOWZA!! We just had multiple strikes on the crew service tower, which is currently not attached to the rocket and is also grounded. Bob is telling Val he wants out *NOW* but conditions are too dangerous for an unnecessary emergency egress. Medical team is evaluating his vitals
Kerbal Space Agency
@KSA_MissionCtrl
the night is pitch black now as overcast skies cover Mun and stars. Pressure has stabilized but rain, high winds and some lightning continues. All visitors have been moved indoors to the VAB, HAB or Astronaut Complex. Flight surgeon says Bob is showing an elevated heart rate
Kerbal Space Agency
@KSA_MissionCtrl
the Presider's motorcade was just departing the Support Village and has been halted since crossing the causeway could be dangerous if the winds continue to get stronger. Pressure drop slowly continues so this is likely. Pad crew is entering the launch bunker. Fuel truck detaching
Kerbal Space Agency
@KSA_MissionCtrl
weather desk has informed FD Lanalye the pressure drop began @ rocket power-up but given no such reaction has occurred after the cooling system was installed they were hoping it would stabilize. No such luck it seems. Clouds are starting to build near the pad, winds increasing
Kerbal Space Agency
@KSA_MissionCtrl
[HOLD] Bob has confirmed he's flipped all the switches & pressed all the buttons needed on his end and the capsule is now initialized, lifter rdy for fueling. Tanker is already hooked up to the service tower but we just got a No GO from the weather desk monitoring a slow pressure drop
Kerbal Space Agency
@KSA_MissionCtrl
AFCS flight instructions update info can be found here: bit.ly/AFCS_ChangeLog - while Bob will handle a lot of normally automated preflight tasks so he's not sitting around bored, during the actual ascent the flight computer will be in command w/ a few manual emergency controls
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h10m] rocket mounted, launch team briefed, Val back on CapCom, Monolith chilled & weather desk has given an improved forecast of 85% favorable conditions @ launch time. We are GO to begin preflight procedures! Bob says he's doing "A-Okay" - voice quaver likely comm distortion
Kerbal Space Agency
@KSA_MissionCtrl
because the rocket will be spending more time in the atmosphere it will be holding a TWR of 1.65 during ascent, which will give Bob a very comfortable ride on the way up as well. This will reduce friction heating but is also necessary to not speed past the landing zone
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h40m] rocket mounting going well, nearing completion while Flight Director Lanalye assembles her A team in launch control for their final briefing on today's mission, which will send Bob downrange at a slightly shallower angle for a lower apokee and gentler re-entry
Kerbal Space Agency
@KSA_MissionCtrl
Commander Val, working CapCom, is actually down at the launch pad right now plugged straight into the capsule so she can keep in touch with Bob during mounting operations and alert the pad crew if anything appears to be going wrong from inside the capsule
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h10m] while rocket mounting continues we are rolling into the more-familiar prelaunch procedures with regional weather reports from stations, airships and maritime vessels being collected for a new forecast. Yesterday's forecast was only 70% favorable but expected to improve
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h20m] crew load was without issue. Although the capsule orientation makes it a bit awkward, lots of training helped. Bob is now situated and his suit life support will remain on internal capsule power until the rocket is mounted and service tower umbilical arm is connected
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h50m] Specialist Bob is ready to begin ingress procedures. He will be assisted into the capsule by the pad crew and then strapped down. The hatch will then be sealed in preparation for the mounting of the rocket
Kerbal Space Agency
@KSA_MissionCtrl
crew photo outside the rear of the Astronaut Complex as Bob boards the crew shuttle out to the pad. Bill will head back inside to the ready room and stand by in case he is needed. Rocket carry vehicle is nearing the pad and will position itself for the vertical lift
Kerbal Space Agency
@KSA_MissionCtrl
[L-5h10m] pre-launch operations have begun as the carry vehicle leaves the VAB with the Mk1 strapped atop, making its way slowly to the pad 655m away over the next 10 minutes. Meanwhile, crew is completing suit up in the Astronaut Complex. Expect updates at these milestones
Kerbal Space Agency
@KSA_MissionCtrl
several hours to go until the start of prelaunch ops but Bob & Bill have already awoken to eat their choice meal before beginning the process of getting suited up for flight. Bill says he slept soundly and Bob admits he had trouble getting to sleep but feels okay

all readiness reports have been submitted, reviewed and approved by @DKerman_KSA - which means we are 🚀 GO FOR LAUNCH! 🚀 launch pad has been reconfigured and is ready to receive the rocket AND CREW tomorrow after rollout. Pre-launch ops begin @ 14:11 UTC
Kerbal Space Agency
@KSA_MissionCtrl
Flight Director Lanalye's A team, with Jeb & Val, are working through final training exercises today while she prepares her launch readiness report. VAB is loading the rocket up onto the carry vehicle while Lead Engineer Simon completes his own report
Kerbal Space Agency
@KSA_MissionCtrl
doctors report both Bob & Bill are in good health and spirits. Both will be equally prepared for tomorrow's launch all the way up to L-0. If we need to swap out the capsule crew for any reason, even after its been buttoned up, Bill will be suited up and ready to go
Kerbal Space Agency
@KSA_MissionCtrl
the amount of ablative material on the heat shield is also not added as a resource to the Ops Tracker since there is no way we can track in flight the amount that has been used during re-entry so no point in showing it
Kerbal Space Agency
@KSA_MissionCtrl
Ascension capsule ECLSS has been properly supplied on all flights with food, water, nitrogen and oxygen however these resources have never been noted in the Ops Tracker since consumption is not vital - more than enough to last thru mission. Longer missions will have them
Kerbal Space Agency
@KSA_MissionCtrl
our new recovery vessel MSV Aldeny has left port in Umbarg to sail out to the recovery zone for tomorrow's mission. Having our own vessel has the potential to reduce mission costs since we no longer have to pay 4,500-6,200 funds to rent one from the Maritime Service fleet
Kerbal Space Agency
@KSA_MissionCtrl
Support Village lodging is already at capacity due to the Presider's presence requiring a security buffer and Monolith pilgrims looking to get in a visit before the temple is shut down prior to launch day. Anyone attending the launch viewing should plan to arrive on the day of
Kerbal Space Agency
@KSA_MissionCtrl
we've added a new visual aid to the streaming telemetry that will notify you when data is outside expected values but within predetermined tolerance (yellow flashes) or outside expected values like WTF oh noes (red flashes). You can check it out here: kerbalspace.agency/Tracker/tracke…
Kerbal Space Agency
@KSA_MissionCtrl
for security reasons we were not allowed to announce earlier that the Presider will be in attendance for this launch, but his flotilla just arrived and docked near the Support Village. We are honored by his presence & acknowledgement of our accomplishments to get to this point!
Kerbal Space Agency
@KSA_MissionCtrl
meanwhile Jeb & Val have remained involved in this mission by taking turns in training with launch team A stationed at Capsule Communications. Sticking to the crew rotation, Val will be primary on CapCom with Jeb as backup operator if she needs to be relieved
Kerbal Space Agency
@KSA_MissionCtrl
medical staff are doing checks on Bob & Bill every day, enforcing a strict diet of meals they dictate, but allowing them to sleep as they feel they need to. All this sets a baseline to help begin to determine what affects spaceflight has on an astronaut after returning to Kerbin
Kerbal Space Agency
@KSA_MissionCtrl
flight analysis is published for last week's Progeny Mk6-II mission and coupled with data from the dayside launch we have our first rough approximation of the true shape of the belts! Full details: kerbalspace.agency/?p=9336
Kerbal Space Agency
@KSA_MissionCtrl
although they can't run sims while stuck in quarantine, Bob and Bill have plenty of written manuals and procedures to review. Of course, they could also be relaxing and binging all the movies & TV shows they didn't have time to watch while training...
Kerbal Space Agency
@KSA_MissionCtrl
last week the capsule was stacked & the rocket is now undergoing final close out checks in the VAB. This flight uses a brand-new capsule. The 1st one is being used for the deceleration testing and the 2nd one that's flown to space twice will be used for further unkerbed missions

@KSA_MissionCtrl
#OTD back in 2017 we were still recovering from the massive outburst unleashed by the Monolith after first reaching space. You can read about it all here: kerbalspace.agency/?p=4567 - the Monolith continues its battle to keep us planetside to this day
Kerbal Space Agency
@KSA_MissionCtrl
today Bob & Bill have both gone into quarantine in the Astronaut Complex, where they will remain away from each other & everyone but medical teams until the mission next week. This is not only to reduce exposure but allow them time to rest from their rigorous training schedule
Kerbal Space Agency

check our Ops Summary for more details on what went down this week, including final mission preparations by Bob and his backup, Bill. Who is ready to witness history next week?? kerbalspace.agency/?p=9332
Kerbal Space Agency
@KSA_MissionCtrl
at this time there are no direct threats to the astronauts but we have had to cancel a few media events outside of KSC over the past month. It's disappointing to see some kerbs that don't want us to succeed in our quest to explore the Kerbol system and beyond
Kerbal Space Agency
@KSA_MissionCtrl
we are bringing in extra security after Monolithic graffiti was found scrawled on the side of the VAB, likely overnight by a religious follower or few who snuck over from the temple to the north. We've been dealing with various protests ever since the kerbed mission was announced
Kerbal Space Agency
@KSA_MissionCtrl
L-7 DAYS UNTIL WE LAUNCH A KERBAL INTO SPACE! This is Bob & Bill's final week for training and they have been training hard. Even when they do something right, they do it right again. And again. Danger is inevitable, risk mitigation is key. Prepare for everything & anything
Kerbal Space Agency
@KSA_MissionCtrl
our 3rd new K2-X engine has arrived, completing the order we placed back in Feb. It is earmarked for the first Ascension Mk2 flight and will be static fired next month when our new test stand completes construction since its flight tank won't be here by then
Kerbal Space Agency
@KSA_MissionCtrl
we gots all the details on what went down this week in our Ops Summary: kerbalspace.agency/?p=9303 We hope everyone has a fun and relaxing weekend. Rocketry teams: rest up!

@spacepotato101 Wow, nice! We will add a link to our program page next week for anyone who wants an alternate summary to the mission reports. Thanks!
Kerbal Space Agency
@KSA_MissionCtrl
the current Presider is running for a second term - he has neither interfered nor directly supported us but has acknowledged our potential for the advancement of kerbal society several times. A third candidate has been for some reason dodgy when asked about us
Kerbal Space Agency
@KSA_MissionCtrl
campaigns are ramping up towards this year's election for a new Presider in December - we are not directly controlled by the political machine however the government can make things difficult for us if they wanted. One of the candidates is heavily tied to Monolithic interests
Kerbal Space Agency
@KSA_MissionCtrl
allow us to remind everyone that bit.ly/KSA_Patreon is a way to help directly fund operations - more money means more rockets means more launches means more exploration! Of course, responsibility still lies with us to also produce viable commercial launch vehicles
Kerbal Space Agency
@KSA_MissionCtrl
swinging back into the red, June financial report leaves us without enough funds to launch an Ascension Mk2 unless we can put a kerbal in space this month. No pressure! Poor CFO Mortimer has quite a bit more gray hairs now... docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
Specialist Bob and his backup Specialist Bill have been working even more closely with Flight Director Lanalye's launch team A in rehearsals leading up to the kerbed mission later this month, while controllers on her launch team B also train for the Mk6 Block II mission
Kerbal Space Agency
@KSA_MissionCtrl
currently the Extremis team has put aside for now the multiple Grand Tour ambitions but are keeping their extra-planetary focus by helping the Ascension team figure out how well their Mk2 rocket is capable of executing individual missions to Minmus, Mun, Eve and Duna
Kerbal Space Agency
@KSA_MissionCtrl
#OTD in 2017 the bit.ly/ExtremisProgram was formed, with the over-ambitous goal of sending out three probes on Grand Tours of the Kerbol system. While we do have a fairly epic 2021 trip start planned for Eve-Jool-Plock, additional multi-flybys have been hard to find

@KSA_MissionCtrl
thanks to a generous donor, we now have our own MSV! It's an old hull, but will serve well as a recovery vessel after some retrofits to the stern to haul capsule aboard. It has been designated the MSV Aldeny & will be training to recover the first kerbed Ascension mission in July
Kerbal Space Agency
@KSA_MissionCtrl
FD Lanalye & her team today conducted a successful static fire of the lifter core that will power the next Ascension Mk1 flight set to carry Specialist Bob into space next month. Test data still has yet to be fully analyzed and verified however
Kerbal Space Agency
@KSA_MissionCtrl
the second of three new K2-X engines has arrived as NovaPunch works to close out the order we placed back in Feb & then get started on last month's order, which will see 3 more engines delivered to us Sept-Nov. So potentially 6 more Ascension flights this year
Kerbal Space Agency
@KSA_MissionCtrl
the flight was designed with very general drag calculations given lack of flight data for the Mk7 so we expect the rocket to under perform more than we would expect of the Ascension Mk1, but it should still make it to the ocean east of Ockr
Kerbal Space Agency
@KSA_MissionCtrl
in addition to checking out the steering and guidance of the Mk7 we'll be using this flight to test a trajectory that could give a more comfortable ride to Ascension astronauts

the sled track will be built along the entire 2.2km length of the paved runway, closing it to flight operations. The Deuce & Civvie however can both land and depart from the turf runways if needed (dotted outline) - Also, new chart ASA-002-R2 has the main runway marked paved now
Kerbal Space Agency
@KSA_MissionCtrl
final rocket sled and track design has been approved after Lead Engineer Simon worked to integrate the capsule into the sled. Dr. Murstap himself has volunteered to do the runs once the track is built (in July) and tested (in August)
Kerbal Space Agency
@KSA_MissionCtrl
Val got a bad sprain today during the astronaut's regular training run. It would not have prevented her from flying but does raise the question - what happens if an astronaut is injured in mission training or becomes sick? The next crew member in the rotation is their backup
Kerbal Space Agency
@KSA_MissionCtrl
the next Progeny Mk6 Block II scheduled to launch on 6/25 is now vertical in the VAB after a routine assembly process. Although an old photo, we do actually have a new Ascension tank and engine in the VAB now as well undergoing inspections
Kerbal Space Agency
@KSA_MissionCtrl
not everyone has given up the search, but even the area the plane was thought to have been found in hasn't been fully covered and expanding the search to an even wider area only means more time will be needed to uncover any possible signs of wreckage
Kerbal Space Agency
@KSA_MissionCtrl
the missing Deuce aircraft remains an aviation mystery - no trace has been found. The best theory accepted by most is the crew got lost, ran out of fuel and crashed. So it could be way, way out of the search area where it had planned to fly
Kerbal Space Agency
@KSA_MissionCtrl
construction wrapped up today at the launch pad for the new crew access tower and service arms. Thanks to a modular design the large pieces had already been assembled off-site and airshipped in for placement. We are now ready to support 5 different rockets on one pad!
Kerbal Space Agency
@KSA_MissionCtrl
the annual symposium of the Kerbal Astronomical Society was held in Kravass over this weekend. Asteroids was a big topic last year, still of concern this year but larger focus was on planetary science as guidelines for proposals for space missions were hashed out. Exciting!

additional big news from the report is that we have agreed to fund Dr. Murstap's deceleration research in conjunction with C7 Aerospace Division to not only benefit space flight but also design safer aircraft in the event of accidents. Two words: ROCKET SLED!!

flight analysis for the last Ascension Mk1 mission has been posted: kerbalspace.agency/?p=9214 - we continue to remain on track to launch a kerbal into space in July. Final major hurdle is the engine test towards the end of this month
Kerbal Space Agency
@KSA_MissionCtrl
astronauts took turns today sealed in the capsule with no power (except life support to their suits) as a stress test. Surprisingly Bill lasted the longest, then in order of decreasing time came Jeb, Val and Bob
Kerbal Space Agency
@KSA_MissionCtrl
the first of our new K2-X engines has arrived - this is the one that could carry a kerbal into space. Because we still have no test stand, the engine will be integrated with its flight tank and static fired out on the launchpad after the 6/20 Progeny Mk7-A flight
Kerbal Space Agency
@KSA_MissionCtrl
#OTD in 2018 we began our quest for orbit with the first launch of the Ascension Mk1 (ops.kerbalspace.agency) ultimately we have since discovered it was not as powerful as we thought we needed for an orbital insertion - but the upcoming Mk2 is!
Kerbal Space Agency
@KSA_MissionCtrl
next Ascension launch will be the last of the original Mk1 lifters built in 2018. New ones that have been ordered will be built with lighter fins & control surfaces now that we better understand the stress on the rocket during ascent, adding more than 150kg to payload capacity
Kerbal Space Agency
@KSA_MissionCtrl
astronauts have been running new sims now that they have actual data to work against in the control of the capsule while the LES tower is attached. The added mass makes a big difference in capsule motion and they need to be well trained both with & without it present
Kerbal Space Agency
@KSA_MissionCtrl
CFO Mortimer is pleased with our gains in May, but we will still be struggling these next few months to afford the test launches needed to draw in more commercial partners and thus more money. it's a vicious balancing game. Full report: docs.google.com/spreadsheets/d…

@KSA_MissionCtrl
ongoing analysis of the last Ascension Mk1 flight still shows re-entry in excess of 16Gs. We either have to fly a lower arc or prove a kerbal can indeed withstand that force without serious effects. We're looking into the latter option, mainly because someone already wants to

learn more details about what went down this past week, including extra information on the new Mobile Launch Platform, in our Ops Summary: kerbalspace.agency/?p=9183 what are everyone's plans for the weekend?
Kerbal Space Agency
@KSA_MissionCtrl
official search and rescue efforts were suspended today, making this the first ever aviation disappearance - no airship/craft as ever gone unaccounted for. Some private pilots have pledged to continue the search - which is entirely over land so the crash site must be *somewhere*
Kerbal Space Agency
@KSA_MissionCtrl
Deuce aircraft from SRG out on a pleasure cruise earlier this week was reported overdue for arrival at KGA according to its filed flight plan. Rescue airships were dispatched into the general area it should have flown through but no trace of the aircraft was found
Kerbal Space Agency
@KSA_MissionCtrl
the MLP can support the rocket unfueled - it will be strutted to the platform while moving. Once at the launch pad the service towers will be attached, the struts removed, and the engine support collar will be installed to help hold the full weight when fueled
Kerbal Space Agency
@KSA_MissionCtrl
you've seen the rocket, you've seen the service structures, you've seen the new boosters, now time to see it all together with the Mobile Launch Platform! This will be our first vehicle to move a rocket to the launch pad vertically from the VAB
Kerbal Space Agency
@KSA_MissionCtrl
with no launches until the Progeny Mk7-A towards the end of next month, work has begun out on the launch pad to erect the crew access tower and reconfigure the service towers to prepare to launch an Ascension Mk2 in July
Kerbal Space Agency
@KSA_MissionCtrl
because this time we flew an ascent path much more closely (to within less than half a degree in most cases) to the planned pitch profile, hopefully the Ascension team will be better able to figure it out & allow us to better aim our future orbital insertions or direct ejections
Kerbal Space Agency
@KSA_MissionCtrl
telemetry data from yesterday's flight is now available. Once again actual ascent came up shorter than planned. We know it's due to excess drag but what we don't yet know is how we are modeling it incorrectly in our ascent design docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
post-launch operations are wrapping up and the capsule plus its heat shield have been pulled from the water to sail back to KSC, they will arrive tomorrow. Expect another 2 weeks or so for mission analysis before we can talk about a possible kerbed flight in July
Kerbal Space Agency
@KSA_MissionCtrl
we lost signal just before splashdown but have data confirmation relayed via Hoodall the capsule is safely afloat in the water and they are moving in to begin recovery operations. ✨🎉 KERZZAH!! 🎉✨

controllers had the time and cold gas reserves to take manual control of the capsule to point it retrograde. It was rolled "up" then maneuvered to the desired orientation without any issues. It is now back under computer control to hold retrograde until re-entry
Kerbal Space Agency
@KSA_MissionCtrl
As we expected, the rocket under-performed due to excess drag that wasn't modeled properly. It's a complex issue & we're still working to determine if it's us not plugging in the right numbers or LVD not doing the right calculations (or bit of both). Burn length was right on time
Kerbal Space Agency
@KSA_MissionCtrl
through apokee now and capsule has successfully oriented along all vectors. It's slower than before thanks to the LES tower but ascent steering is also not fighting for control this time. Just under half of cold gas capacity has been used up so far
Kerbal Space Agency
@KSA_MissionCtrl
MSV Hoodall is repositioning for recovery as capsule will be coming down ~20km short of its intended landing site, but still over water. We're about 4 minutes from apokee & capsule orientation commands are still underway
Kerbal Space Agency
@KSA_MissionCtrl
capsule separation was good & RCS thrusters fired for 10s to push it away from the lifter stage so it has room to maneuver. Controllers are sending it orientation commands while trajectory analysis is underway to see how the lower apokee affects the capsule return
Kerbal Space Agency
@KSA_MissionCtrl
MECO several seconds early, rocket coasted out of the atmosphere and we are now standing by for confirmation of capsule separation. As expected, we came up short of our target apokee - capsule will fly up to only 485km. That's a larger discrepancy than we hoped for though
Kerbal Space Agency
@KSA_MissionCtrl
nominal ascent so far. Just passing Mach 2 now, velocity 630m/s, altitude approaching 16km. Some transonic rollshake noticeable but guidance remains on target. Just under one minute left of fuel and then we'll be coasting through spaaaaaaace
Kerbal Space Agency
@KSA_MissionCtrl
main engine start was nominal, throttle up to TWR of 1.2 achieved and lift off occurred right on time. Rocket will shortly clear the tower and begin to roll before pitching downrange - this is the first time we are rolling the rocket off the pad in prep for the Mk2, which has a fixed launch orientation
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] countdown continues! We have a final poll of primary launch stations coming up at T-30s followed by these events leading up to T-0. Stand by, and be sure to load up the Ops Tracker for live updates! ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] back in the terminal countdown, AFCS has commanded the service arms to swing away and leave the rocket to its own internal resources. Battery drain and RF comms check underway - capsule telemetry should remain solid this time around
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] we are GO from all stations to continue the final count! Weather desk came back green on upper-level turbulence after some consultation with the engineers. FTS is on internal power, service arms are again unlocked for retraction, AFCS standing by
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] we are back to range closure, the RSO has announced rocket is ARMED and FTS/LES has been re-activated. Two minutes from now pressurization gas will be loaded back onto the rocket. Controllers working to ensure all systems were properly reset for new L-0
Kerbal Space Agency
@KSA_MissionCtrl
capsule is being sealed back up. Weather team had some concerns about upper-level turbulence & released their backup balloon shortly after the hold was called - countdown will pick back up at L-15min @ 18:15 UTC to ensure balloon has enough time to reach altitude
Kerbal Space Agency
@KSA_MissionCtrl
problem resolved - a wire harness was not fully plugged in & shook completely loose upon service arm retraction, which does jostle the rocket a bit. Now waiting for a battery swap to complete, since capsule has just enough EC for a mission that launches on time
Kerbal Space Agency
@KSA_MissionCtrl
countdown has been rolled back to L-15m & crew are preparing to enter the capsule by climbing the service tower, walking out atop the upper arm, hooking onto the LES tower & swinging around to the hatch. It's a procedure already in place for medical emergency pad egress
Kerbal Space Agency
@KSA_MissionCtrl
FD Lanalye reports that this won't be a quick fix - it has to be a loose cable inside the capsule. Controllers are backing off from launch readiness and prepping the rocket to be disarmed, hooked back up and depressurized. We still hope to launch before nightfall though
Kerbal Space Agency
@KSA_MissionCtrl
[HOLD] countdown was stopped shortly after terminal count when part of the telemetry from within the capsule was lost. That data is vital to this mission and needs to be brought back up. Team is working the problem - rocket remains on standby
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] terminal countdown has begun! Service tower arms have swung away from the rocket, no longer supplying power so batteries have switched on. Landline comms also cut so RF comms being checked for good signal. AFCS has control of the countdown
Kerbal Space Agency
@KSA_MissionCtrl
[L-3m] preliminary tank pressurization underway to give the rocket extra rigidity so it can stand atop the engine collar once the service tower arms swing away in one minute at the start of the terminal countdown - ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] Final readiness polls complete: Wx: GO; Range: GO; Flight: GO; Tracking Station: GO; Downrange Tracking: GO; Ops Director @DKerman_KSA: Launch permission granted! 🚀GO ASCENSION🚀 FTS power internal, service tower booms unlocked for retraction, AFCS rdy for terminal count
Kerbal Space Agency
@KSA_MissionCtrl
[L-13m] with the pad cleared, onload of nitrogen gas for pressurization of the fuel tanks has begun remotely from a tanker truck left hooked up to the service tower. Itself stored in a pressurized vessel, any rupture would be a danger to crew
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] RSO has closed the range - rocket is ARMED and Flight Termination System/Launch Escape System is activated. Anyone or anything spotted within 500m of the launch pad will hold the count. Anything within 25km airspace & 50km at sea will do the same
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] thumbs up from the weather desk and final countdown procedures are GO! Team is resetting from the rehearsal and switching all consoles back over to the live rocket, pad workers are performing final close-outs
Kerbal Space Agency
@KSA_MissionCtrl
[L-45m] all systems are set, all assets are in place so it's time for the team to run through a full launch rehearsal to make double sure everything is as it should be and all participants know their roles - including in the event of trouble
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h20m] high-altitude KerBalloon has begun its ascent to give us a reading on upper-level winds by the time final polls roll around at L-5min
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h30m] rocket is all prepped to go! MSV Lymun is on station 15km offshore and working to get setup with the Range Safety Officer. MSV Hoodall is within comm range in the landing zone east of Ockr & reports they are ready for recovery operations
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h55m] preliminary pre-flight checks are now complete, no issues currently being worked. Pad crew has secured the rocket and are clearing out minus the QRT members in the bunker. Once the all clear is given, controllers will run engine systems & ignition checks
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h40m] tanking completed on schedule without issue, pad workers are now cleaning things up & securing the rocket while launch controllers resume preflight checks, keeping a close eye on tank levels to ensure no leaks are present
Kerbal Space Agency
@KSA_MissionCtrl
the only reason we're using the single truck to shave time off the countdown is so that it's less time the eventual astronaut aboard has to wait for lift off, since they are put into the rocket before it's raised vertical and fueled
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h55m] rocket systems are online & configured for tanking. Pad crew has a GO to begin onload of 7t liquid propellant. We've cut 20min from our countdown thanks to a huge fuel truck (originally purchased for Dhumla) that can top off the rocket in one go
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h10m] we are GO for preflight! Forecast has improved to 95% favorable and launch team is on console waking up the rocket to onload flight instructions to the AFCS - you can check out the latest update here: bit.ly/AFCS_ChangeLog
Kerbal Space Agency
@KSA_MissionCtrl
the rocket should fly much closer to the planned ascent profile this time (red dots), but we still expect it to under-perform as it will probably experience more drag than is modeled. Hopefully though with smaller margins than last time
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h40m] Wx data has been gathered & is being processed while Flight Director Lanalye gives her launch team their final brief. This mission will follow the same major steps as the one last month, with tweaks to the ascent profile for a slightly flatter trajectory
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h10m] yesterday's weather forecast was 85% good launch conditions but a new forecast is being assembled now as we roll into prelaunch operations. Timeline has been slimmed - can you see where? Expect updates at these major milestones in the sequence

Kerbal Space Agency
@KSA_MissionCtrl
Bluedog Design Bureau won the contract for heavier-duty radial booster couplings for the Ascension Mk2 since the smaller ones used on the Progeny Mk6 Block II would have failed during ascent and also these have to do more than just hold the booster to the lifter
Kerbal Space Agency
@KSA_MissionCtrl
Ascension Mk1 rocket has been rolled out and hooked up to the service towers for launch controllers to do a systems check while the rest of KSC continues to prepare their launch readiness reviews. Downrange tracking stations are doing the same
Kerbal Space Agency
@KSA_MissionCtrl
this weekend workers will finish up a radio relay tower placed at 5.2km ASL - so high workers need to wear oxygen masks. This will allow us to extend sub-orbital flights further downrange & still stay in contact with Ockr on returns
Kerbal Space Agency
@KSA_MissionCtrl
report from Lead Engineer Simon is the Ascension Mk1 has completed final checkouts and has approval to be loaded up for rollout on Monday ahead of launch on Tuesday. Launchpad underwent checks today as well to ensure it is ready to receive the rocket
Kerbal Space Agency
@KSA_MissionCtrl
another step successfully taken on the path to kerbed flight - Ascension Mk1 ascent abort test was well-within tolerances for crew survival. Full flight analysis now available: kerbalspace.agency/?p=9148
Kerbal Space Agency
@KSA_MissionCtrl
being able to eject from the system also means the Mk2 could reach Minmus and Mun. Whether the payload mass that could get there would be enough fuel to enter into orbit is unknown. Extremis team is being leveraged to help w/these calculations. Still, even fly-bys would be great!
Kerbal Space Agency
@KSA_MissionCtrl
Ascension program has been working on determining the upper-limits of the Mk2 and the results are surprising. It has the potential to send a 255kg payload direct into kerbolar orbit, possibly to Duna or Eve - that's the next thing they will be looking at with LVD
Kerbal Space Agency
@KSA_MissionCtrl
Ascension Mk1 for next week's launch has been stacked vertical in the VAB today for fit and load checks, which is just the capsule being placed atop the lifter. Tomorrow it will be laid out horizontal for final checks prior to loading up on the carry vehicle Monday
Kerbal Space Agency
@KSA_MissionCtrl
the Mk1 will still be rolled out horizontally so the astronaut will board just prior to the rocket being raised vertical. The new launchpad configuration will still be able to support Progeny Mk7 launches as well
Kerbal Space Agency
@KSA_MissionCtrl
the Ascension Mk2 will require a reconfiguration of the current umbilical towers (top one stays put, becomes bottom while bottom one is built higher up) plus the addition of a new crew access tower since the Mk2 will be rolled out vertically from the VAB
Kerbal Space Agency
@KSA_MissionCtrl
the extensible truss is mainly to protect the spacecraft from heat generated by the RTG (for those that carry the most fuel) but it can also be useful to control spin rates when placed appropriately - mostly a planned feature for our Extremis probes
Kerbal Space Agency
@KSA_MissionCtrl
our partnership with Coatl Aerospace continues to bear fruit as they have submitted the final design revision of the RTG that has been under development the past year and a half and will be integrated into our first commercial satellites

telemetry data from yesterday's flight is now available, with a full analysis coming by the end of the month once the Ascension team is able to look closely at how the capsule and its test occupant Greggery ultimately fared docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
capsule is out of the water and being delivered back to KSC for post-flight analysis. Mission was a success in gathering the data needed but ultimately we have yet to determine if the LES did indeed operate within tolerances for a future onboard crew member
Kerbal Space Agency
@KSA_MissionCtrl
Tongjess got a good view of the capsule as it made its final decent under full chute and splashed down 32.429km downrange just off shore at the north end of the bay. Capsule heat shield was dropped and float collar deployed. Recovery operations are underway
Kerbal Space Agency
@KSA_MissionCtrl
good chute deploy as seen from ground tracking camera, canopies are reefed to create extra drag and slow the capsule as it descends into thicker air. They will fully deploy <1km above the surface to arrest descent and allow the capsule to land at around 5m/s
Kerbal Space Agency
@KSA_MissionCtrl
clean capsule separation! It is just about to finish coasting up to an apokee of ~35km. Flight computer will command the chute to pop at that point but the chute's own pressure mechanism will hold it in until the capsule falls below 30km
Kerbal Space Agency
@KSA_MissionCtrl
nominal ascent, rocket is stable and passing through 15km - coming up on capsule release in just a few seconds at 18.5km. Velocity is currently >600m/s (Mach 2)
Kerbal Space Agency
@KSA_MissionCtrl
good engine start, chamber pressure checks out for 1.2 TWR launch power - clamp release and lift off! Rocket will clear the launch tower and throttle up to full power and begin to pitch over downrange

you could hear a pin drop in launch control right now - but that's good! Everyone quiet means no issues being worked as all stations do a final review of their data to be ready to announce their go/no go status at the upcoming polling
Kerbal Space Agency
@KSA_MissionCtrl
[L-13m] tanker truck left hooked up to the service tower has been remotely commanded to begin pumping nitrogen onboard to be used to pressurize the fuel tanks. Late onload of the gas is to ensure any tank rupture doesn't endanger pad workers
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] RSO has closed the range, rocket is now ARMED and Flight Termination System/Launch Escape System has been activated. Anyone or anything spotted within 500m of the launch pad will hold the countdown from this point on
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] we are GO for final countdown procedures! Weather remains well within our loose constraints for today and now the Range Safety Officer is making sure all launch areas are clear and the eastern range is void of ships or aircraft

Kerbal Space Agency
@KSA_MissionCtrl
[L-1h20m] we will not be launching a high-altitude weather balloon today because we won't be flying through the upper atmosphere - also because Mortimer got stingy with funds and we actually don't have any more (but some additional units are now on the way for next launch)
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h30m] all rocket and capsule systems check out - FD Lanalye reports the vehicle is ready for flight! MSV Tongjess has sailed out to just over the horizon to ensure the eastern range stays clear and be ready to move further downrange after launch for recovery
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h55m] no issues being worked, launch operations proceeding on schedule. Pad is now clearing out except for a Quick Response Team sheltering in the bunker as controllers begin to check over the main engine ignition and control systems

@KSA_MissionCtrl
[L-2h40m] after a trip back to the VAB to refuel the tanker trucks have completed their task on schedule. Preflight is resuming in launch control while pad workers get things cleaned up and locked down. Tank levels will be closely monitored to ensure no leaks are present
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h15m] rocket is fully woke, weather remains stable and GO has been given to begin fueling, adding 7t of liquid propellant. The lifter stage will simply burn out and crash back onto the surface after the capsule separates. Look out below!

Kerbal Space Agency
@KSA_MissionCtrl
[L-4h] final mission brief under way at launch control. Flight will be relatively simple - after rocket ascends into the upper atmosphere the capsule will be detached and flown away using the Launch Escape System. It will then descend ballistically for splashdown
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h30m] rocket was mounted earlier without issue and time has come for pre-launch operations to kick off. Launch teams are assembling across campus as the weather desk begins collating reports from stations & airships to build a forecast. Expect updates at these milestones:

Kerbal Space Agency
@KSA_MissionCtrl
both Progenitor and Ascension teams are working together today to turn around the launch facilities and get everything ready for the Ascension Mk1 ascent abort test tomorrow. The mission is basic enough to allow the launches to happen almost back to back
Kerbal Space Agency
@KSA_MissionCtrl
Mk6 is on its way out to be mounted. Progeny rockets have their own carry vehicle but it won't do any longer once the Mk7 comes around - those will use the same carry vehicle that bears the Ascension Mk1. The Ascension Mk2 will also use its own, much bigger, vehicle
Kerbal Space Agency
@KSA_MissionCtrl
For now, the camera only stores/transmits back images at specific times to help confirm important events, like the payload separation. This image we posted earlier was nice from a PR standpoint, but for mission analysis it helped confirm the deflection of the elevator controls
Kerbal Space Agency
@KSA_MissionCtrl
the one example of video from the booster cam we have was just a short clip stored on the payload and unable to be viewed until the test mass was recovered. We are definitely looking to someday be able to both store and watch video from the booster camera
Kerbal Space Agency
@KSA_MissionCtrl
kerbs have been asking for video of an Ascension Mk1 launch into space but we're sorry to say we actually don't have any footage! Yes, that's a video cam on the booster but there is not much room in the capsule to store video footage or transmission bandwidth to beam it back
Kerbal Space Agency
@KSA_MissionCtrl
we are all still reeling from the events of yesterday. Aldeny will be a sorely missed ray of sunshine around campus - his energetic personality could motivate anyone. Altho it's hard, we must push on in his memory. Our Ops Summary has details on that: kerbalspace.agency/?p=9083
Kerbal Space Agency
@KSA_MissionCtrl
Progeny Mk6 has been laid horizontal for final payload checkouts before they button up the fairings and load it up onto the carry vehicle for rollout on Monday. The ascent abort test Ascension Mk1 lifter will have the capsule stacked atop it today for fit & load checks
Kerbal Space Agency
@KSA_MissionCtrl
despite best efforts to repair & refurbish, the L thrusters at the base of the Mk1 capsule saw too much damage during re-entry to be re-used on the next flight. The I thrusters used for roll control however still function well & will be tried for a consecutive mission
Kerbal Space Agency
@KSA_MissionCtrl
test stand will be rebuilt to better specs by August and the 3 engines already partway assembled are being resumed with an order for 3 more placed today. First new engine should arrive next month to be used on the Mk1 flight we hope will carry a kerbal into space by July
Kerbal Space Agency
@KSA_MissionCtrl
some good news today at least: K2-X engine has been cleared. Final report is the fuel tank, which was constantly re-used for each test, fatigued & shed some of its interior lining due to poor dampening. This entered the engine causing a cascading failure of the fuel pump system
Kerbal Space Agency
@KSA_MissionCtrl
deadline for number submissions will be midnight UTC on 5/15. Next Monday we will announce the date on which we will hold the selection process, which we are planning to live stream to ensure everyone can see there was no backroom meddling
Kerbal Space Agency
@KSA_MissionCtrl
who will be the first astronaut to go to space? All 4 of our original crew have trained for the privilege and now we want YOU to help us select the one to get the honor! All you need to do is reply to this tweet with 5 numbers between 0 and 100 (they don't all have to be unique)
Kerbal Space Agency
@KSA_MissionCtrl
one day we'll have spacecraft in orbit that can confirm such events, either directly or by their after-effects. In this case, the dust will likely fall into the ocean and create a super bloom of microscopic plant life feeding off the nutrients within it. Ain't life amazing?
Kerbal Space Agency
@KSA_MissionCtrl
low-altitude KerBalloon crew have returned from a successful mission with no report of being directly affected by an asteroid impact. They did note the sky took on a reddish tinge from dust however as they were leaving so it seems there was an impact
Kerbal Space Agency
@KSA_MissionCtrl
sliding backwards again, April financial report just published by Mortimer shows we should still have just enough money even if we continue to suffer losses to make to where we can launch commercial payloads later this year. Otherwise R&D will be shut down docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
if both missions go well, then the 3rd will send the first astronaut up no earlier than July - we'll need to get the first of the new engine shipment that was put on hold back in Feb, integrate it, test it & we are also still working on the 2nd new Mk1 capsule integration as well
Kerbal Space Agency
@KSA_MissionCtrl
Ascension team have finished planning out the use of the remaining 3 Mk1 lifters - ascent abort test will take place right after the Progeny Mk6-I mission on 5/16 @ 21:48 UTC followed by a re-fly of this past mission for more testing on 5/28 @ 16:28 UTC ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
TL;DR - everything remains on track to launch the other 3 Mk1 lifters currently in the VAB - one will fly an ascent abort, another will re-fly this past mission w/proper LES usage & return. If all still looks good, an astronaut will go on the 3rd rocket!
Kerbal Space Agency
@KSA_MissionCtrl
we've been dropping bits of important analysis results from this month's Ascension Mk1 launch here and there but for all the details on what went on during the mission you can now check out the full report: kerbalspace.agency/?p=8976
Kerbal Space Agency
@KSA_MissionCtrl
suffering minimal damage during re-entry, the Mk1 capsule from the last flight can be reflown. We would likely not refly a capsule for a kerbed mission, but for another uncrewed test the capsule is in good enough condition and will save us some much needed funds
Kerbal Space Agency
@KSA_MissionCtrl
HAB workers are getting the hangar cleaned up & the K2-X engine investigation is moving all its material offsite as it wraps up work and hopes to release results in a few days. Dhumla will be getting a full check-over this week in preparation for flight tests to resume next week

@KSA_MissionCtrl
two of the remaining three Ascension Mk1 lifters are having their horizontal fins angled 5° as the recent ascent showed it was successful at giving the rocket more nose-down pitch control while still allowing the elevators to pitch the nose up or hold level when needed
Kerbal Space Agency
@KSA_MissionCtrl
we've realized that our earlier tweet could be misleading - the Ascension Mk2 will likely *not* make its 1st flight w/ a capsule on top, but eventually it will. First mission or two would prove orbital placement with a test mass or commercial probe payload twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
our astronaut crew are readying for a full day of physical evaluation, both medical and aerobic - it's important we gather regular data on their health and performance for a baseline to compare against after their return from spaceflight (and one day, during spaceflight!)
Kerbal Space Agency
@KSA_MissionCtrl
the heat shield dropped from the Mk1 capsule shows only 2.5% of its surface was ablated away during re-entry. This is good news because a thinner heat shield can save as much as 180kg - atop an Ascension Mk2 upper stage that's an extra 65m/s of Δv
Kerbal Space Agency
@KSA_MissionCtrl
pad workers have been inspecting the launch towers and engine clamps and Lead Engineer Simon reports the amount of wear they are experiencing is less than predicted for this many launches, meaning we can choose to let loose an Ascension rocket at full thrust if needed

bit.ly/AscensionProgr… team have decided there's no mission profile that fits the Mk1 Block II so it will be merged with the Viklun Mk1 to create a single vehicle: the Ascension Mk2. So the Mk1 will carry sub-orbital payloads and the Mk2 will be for orbital missions
Kerbal Space Agency
@KSA_MissionCtrl
re-entry data from last week's flight shows Greggery experienced a crushing 17G of peak force - survivable but not without some possible nasty side-effects. We're aiming for 10-12G and may need to shoot for a lower altitude next time or just go further for a flatter trajectory
Kerbal Space Agency
@KSA_MissionCtrl
because it uses a lot of major parts that have already been manufactured, the first launch could be as early as June and interspersed between the launches of our remaining three Ascension Mk1 lifters (although one is still missing an engine)
Kerbal Space Agency
@KSA_MissionCtrl
say hello to the Progeny Mk7-A, the first iteration on the path to a cheaper small-sat option for deploying 0.35-0.625m payloads to low-Kerbin orbit (<250km). Unable to make orbit, this rocket will be a technology pathfinder. More info: kerbalspace.agency/?p=8963
Kerbal Space Agency
@KSA_MissionCtrl
#ICYMI we had our latest rocket launch this week. Here is the Ascension Mk1 Block I lifter carrying the Mk1 capsule for a test ride into space (unkerbed) clearing the tower moments after liftoff. For more on the mission see our Ops Tracker: ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
we're not digging any deeper into this week's flight, but if you fear you may have missed anything these past few days you'll find it in our weekly Ops Summary: kerbalspace.agency/?p=8957 a well-deserved rest to all our rocketry team members this weekend!
Kerbal Space Agency
@KSA_MissionCtrl
even though this ascent trajectory wasn't as demanding as the last, the real goal was to follow the programmed path as closely as possible to better analyze the accuracy of the Launch Vehicle Designer and in this the rocket was successful
Kerbal Space Agency
@KSA_MissionCtrl
ironically the heavier payload of yesterday's flight meant the rocket flew a more vertical trajectory than the last when it was modified to be able to fly more horizontal. The two paths diverge downrange thanks to the LES malfunction, which sent the rocket off radially
Kerbal Space Agency
@KSA_MissionCtrl
here's a view we'll never get tired of - Kerbin from the edge of space. Taken shortly before MECO. The outside pressure is near vacuum and the engine plume has expanded into a gaseous cloud
Kerbal Space Agency
@KSA_MissionCtrl
Ascension team will begin reviewing yesterday's flight over this next week or two and determine what went right/wrong & good/bad - but you can draw your own conclusions (literally - graphs!) with the flight telemetry available here: docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
both the capsule and heatshield will be back at KSC late tomorrow and we may also have some preliminary analysis of the flight to share, but the full analysis will not be available until at least the end of the month
Kerbal Space Agency
@KSA_MissionCtrl
✨🎉 KERZZAH! 🎉✨ we have word from MSV Tongjess that they located the capsule still afloat, altho it took extra time to find the heat shield, which detached moments before splashdown to reduce damage for post-flight inspection & clear the way for the float collar to deploy
Kerbal Space Agency
@KSA_MissionCtrl
post-launch operations winding down - KerBalloon probe was returned after splashing down & Lymun has moved off station, launch pad confirmed clear of any debris and all equipment is in good shape. Launch team debrief has wrapped & all data is prepped for review starting tomorrow
Kerbal Space Agency
@KSA_MissionCtrl
we lost signal shortly after initial chute deployment but it's good to know at least that they have popped out! Now we must wait and hope - Tongjess is still over 1.5hrs away from the new recovery zone & may not be able to still contact Ockr when they get there
Kerbal Space Agency
@KSA_MissionCtrl
just enough cold gas remained to get capsule re-oriented properly and re-entry is now in progress. During this time, after MaxQ, is when we were going to fire the LES push motors to see how it affected the capsule for potential future use as an emergency braking system
Kerbal Space Agency
@KSA_MissionCtrl
radial out orientation finally achieved after resetting the control system - it seemed to still want to orient along the ascent trajectory & was fighting with radial out hold command. Cold gas almost used up so RCS switched off so capsule can point retrograde before re-entry
Kerbal Space Agency
@KSA_MissionCtrl
capsule is thru apokee - LES tower burn took our original apokee of 423km and boosted it up to 506km. New trajectory puts re-entry ~100km further downrange than planned so Tongjess is already on the move. RCS testing continues - capsule having trouble orienting radial out
Kerbal Space Agency
@KSA_MissionCtrl
parachute had to be disarmed so it wouldn't try to pop out as soon as the capsule re-entered the atmosphere, but otherwise all systems are looking good. Controllers have begun to send orientation commands to point the capsule various directions & fully check out the RCS system
Kerbal Space Agency
@KSA_MissionCtrl
RCS system has zeroed out the tumble and capsule has been re-oriented to hold prograde. Rate of turn confirms the LES tower has indeed been detached. Controllers still working to determine any additional ways this unexpected event could affect the mission
Kerbal Space Agency
@KSA_MissionCtrl
we are dealing with an unplanned triggering of the Launch Escape System just after capsule separation! Controllers are working to recover the capsule, which has gone into a bit of a tumble. LES tower has burned out and reports that it detached
Kerbal Space Agency
@KSA_MissionCtrl
hello again, space! Overall ascent was nominal, with acceptable deviation from planned trajectory (MaxQ was late, apokee is low). Control team plotting new course to see how it will affect the rest of the mission. Standing by for capsule separation in just a few seconds
Kerbal Space Agency
@KSA_MissionCtrl
just over halfway to space and all systems remain nominal. Pitch deflection barely at 50% which means the angled fins are doing their job well. Some roll wobble detected going supersonic but rocket remains stable overall and on the planned track
Kerbal Space Agency
@KSA_MissionCtrl
engine startup nominal, chamber pressures good, throttle-up to 1.2TWR successful and we have lift off!! Rocket will clear the tower before going full thrust, saving wear on the pad infrastructure, then enabling guidance control to begin pitching over as it heads downrange
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] if all is GO at 30s final primary polls then the following steps will take place leading up to launch. Don't forget to tune into the Ops Tracker for real time updates! Stand by! ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] we are GO for terminal count. AFCS now has full control of the rocket, which is switching over to internal power and RF comms. Battery drain levels and comm signal will be checked prior to final primary polls at T-30s
Kerbal Space Agency
@KSA_MissionCtrl
[L-3m] tank pressurization has begun to ensure that fuel flow to the engine remains constant and also provide extra rigidity to allow the rocket to stand on its own atop the engine clamp after umbilicals swing away prior to launch
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] Final readiness polls complete: Wx: GO; Range: GO; Flight: GO; Tracking Station: GO; Downrange Tracking: GO; Ops Director: Launch permission granted! 🚀GO ASCENSION🚀 FTS on internal power, service tower booms unlocked to prep for retraction, AFCS ready for terminal count
Kerbal Space Agency
@KSA_MissionCtrl
[L-13m] nitrogen gas has started to get pumped onto the rocket from a service truck left hooked up to the tower. The pressurized gas is loaded late to prevent any injury to pad workers should a tank rupture
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] RSO has closed the range, rocket is ARMED and Flight Termination System, including the LES, is ACTIVE. Arming allows a few final checks to be performed on the engine. Weather desk is analyzing upper-wind data just now coming in from the balloon probe
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] Final countdown! No problems arose during rehearsal and weather is still green. Final health checks of various systems are underway and the last pad workers are loading up to be trucked away from the rocket so it can be armed for launch
Kerbal Space Agency
@KSA_MissionCtrl
[L-45m] launch control is performing a final check of the onboard software and then running a launch rehearsal to ensure all systems and assets are setup and properly configured for the mission. Lanalye also likes to sometimes throw in some issues as well
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h20m] high-altitude KerBalloon has been released from the deck of the Lymun as light winds are blowing off the sea today. It will ascend above 18km into the upper atmosphere shortly before final poll to give us an idea of what upper-level wind conditions are like
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h30m] countdown continues on schedule. With preflight wrapping up focus shifts off the rocket and to the surrounding/supporting infrastructure. Pad is being closed out & secured while Range Safety Officer works with MSV Lymun, on station offshore, to setup range monitoring
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h55m] preflight continues without major issue, now coming up on engine checkouts which require the pad crew to evacuate. Rocket remains unarmed but always better safe than sorry when dealing with something as combustible as rockets
Kerbal Space Agency
@KSA_MissionCtrl
as usual, it is important everyone stick to the designated viewing areas if you are here to spectate the launch. Anyone seen entering the 500m keep out radius will be escorted off campus. If it happens after L-15m you'll also hold up the entire countdown! How about no
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h40m] sun has set and tanks are topped off after the trucks each made a trip back to the VAB for refueling. Pad workers are cleaning up while the launch team continues preflight, keeping a close watch on tank levels to ensure there are no leaks present
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h15m] tanker trucks are already hooked up to the service tower, fuel system is initialized, valves are open and the GO has been given by the launch team to begin onloading propellants, totaling 7 metric tons of liquid fuel and oxidizer
Kerbal Space Agency
@KSA_MissionCtrl
check out bit.ly/AFCS_ChangeLog for the latest software update, which is quite large to take into account the many operations of the capsule and new Launch Escape System
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h30m] launch team is rdy, Monolith temple is chilled & we have a GO from the weather desk to begin preflight by waking up the rocket to prepare for tanking operations. Capsule is fully-automated - when kerbed it will simply be more resilient to failure via manual operation
Kerbal Space Agency
@KSA_MissionCtrl
finally, the timeline & data in the previous images are known to be approximations - the rocket will not follow the ascent trajectory perfectly even if it does manage to pitch over faster due to software guidance limitations. But it should be close enough for similar results
Kerbal Space Agency
@KSA_MissionCtrl
additionally the flight profile had to be adjusted to account for the capsule weighing more than anticipated, mainly due to not factoring in the LES on the last flight. Result is the rocket will now carry a full load of fuel to haul the extra ~300kg on a similar trajectory
Kerbal Space Agency
@KSA_MissionCtrl
the previous mission attempted a similar trajectory but the rocket did not have enough pitch authority to lower its nose far enough. This rocket's elevator fins are themselves pitched to provide downward force in addition to the control surfaces, tho ascent is a bit steeper
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h] launch team has assembled for their final briefing from Flight Director Lanalye. Here's a comprehensive look at today's mission, which will be similar to the last flight except using the actual capsule instead of a test weight. Also some LES usage experimentation
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h30m] pre-launch operations officially kicking off as all teams report for duty. Shuttle buses for visitors viewing the launch will begin to run across the causeway from the Support Village in 30min. We will have updates at the following milestones in the countdown
Kerbal Space Agency
@KSA_MissionCtrl
Monolith temple has been closed up and chilldown has begun to lower the internal temperature to below freezing by the time the rocket is switched on, robbing it of the heat energy needed to form severe storms and endanger the launch

final readiness review is complete, Ops Dir @DKerman_KSA has signed off the paperwork and we are 🚀 GO FOR LAUNCH 🚀!! Weather is looking great with over 95% chance of favorable conditions. Pre-launch operations will kick off tomorrow at 15:42 UTC. Get hype!!
Kerbal Space Agency
@KSA_MissionCtrl
tracking station has confirmed they are ready to monitor tomorrow's launch and coordinate with the downrange stations. We also have confirmation that MSV Tongjess has left port in Umbarg to set sail for the recovery zone - hopefully the payload makes it there this time!
Kerbal Space Agency
@KSA_MissionCtrl
Flight Director Lanalye has been rehearsing her team hard for the past 2 weeks and reports they are ready to support tomorrow's launch, which will be conducted as an automated flight since it will just be the test dummy Greggery going for the ride (tho capsule ECLS is supplied)
Kerbal Space Agency
@KSA_MissionCtrl
mounting has been completed without issue, the Ops Tracker is now updated with dry mass/resources information (ops.kerbalspace.agency). Pad crew now working to get the launch tower umbilicals connected while the rest of KSC also works through launch readiness checks
Kerbal Space Agency
@KSA_MissionCtrl
the rocket has left the VAB and is doing the slow(er) roll to the launch pad, putt-putting along at just 1m/s (slightly faster than the average walking kerbal) taking ~11 minutes to travel to the pad 655m away. It used to travel a bit faster but w/capsule the mass is near limits
Kerbal Space Agency
@KSA_MissionCtrl
Sheltered Rock and Ockr have confirmed they are both ready to deliver downrange tracking for this week's launch. For orbital launches, we also have DSN Central. Nothing to the south? No worries - anything we launch south will also eventually pass over areas north of the equator
Kerbal Space Agency
@KSA_MissionCtrl
our order for 3 additional K2-X engines, scheduled to be filled at the end of this month, remains on hold until the completion of the investigation into the explosion that occurred during static firing back at the end of Feb. Extra checks were made on the engine for this launch
Kerbal Space Agency
@KSA_MissionCtrl
with this week's launch fast approaching, the Ascension Mk1 lifter in the VAB has been fully stacked, laid horizontal and will be undergoing final closeouts today in preparation for loading onto the carry vehicle for transportation out to the pad tomorrow
Kerbal Space Agency
@KSA_MissionCtrl
also, while we will eventually have an 0.625m LF/O vacuum engine designed for satellites that will be more powerful for a few dozen extra kilos of mass, this engine is vastly simpler and thus more reliable for the years-long service time most satellite missions will require
Kerbal Space Agency
@KSA_MissionCtrl
the cold gas engine is nowhere near powerful enough for orbital insertion, which is why it was so important that the Viklun upper stage was designed to be able to reach orbit on its own and reduce the requirements placed on the payload to allow more mass for instruments
Kerbal Space Agency
@KSA_MissionCtrl
our partners over at Archtagon Aerospace have come up with a cold gas engine future satellites can use to adjust their orbits with the same resources needed for orientation at better efficiency with greater thrust (so better than placing 4 or even 8 thrusters pointing aft)
Kerbal Space Agency
@KSA_MissionCtrl
we bet you all thought *next week* was going to be the exciting one! We made quite a few ambitious announcements this past week, so let's take a closer look at what still needs to be done to get something up into orbit in our Ops Summary: kerbalspace.agency/?p=8935
Kerbal Space Agency
@KSA_MissionCtrl
the overall success rate so far for every mission we've conducted across all programs is 86% - not too shabby! You can see success rates for individual programs on their page (kerbalspace.agency/?page_id=1824) & also success rates for individual vessels
Kerbal Space Agency
@KSA_MissionCtrl
one week to our next launch (ops.kerbalspace.agency) and while the rocket gets ready in the VAB work has also been done out on the launch pad to ensure that it is all set to support the launch. Photo taken just a short while ago at 3rd sunset
Kerbal Space Agency
@KSA_MissionCtrl
our astronauts officially have a ride into orbit! Assuming everything was modeled properly, the Ascension Mk1 Block II lifter + the Viklun orbital stage can successfully place a capsule into a 40° inclined 100km circular orbit with ~230m/s of spare Δv! Here's a full render
Kerbal Space Agency
@KSA_MissionCtrl
announced earlier this week, our Viklun orbital stage still doesn't have its own tab on the Ascension program page as we're working out how we want to identify this vehicle on the site and Ops Tracker, since the lifter stage also has its own patch & blueprint...
Kerbal Space Agency
@KSA_MissionCtrl
thankfully no one was seriously injured by the rocks they were pelted with. We have a writeup on the site to provide more info on what happened: kerbalspace.agency/?p=8922 the government is currently discussing what actions, if any, should be taken to contact these isolated kerbs
Kerbal Space Agency
@KSA_MissionCtrl
our high-alt KerBalloon crew is back, partially successful since they failed to recover 1 of the 2 balloons. Why they failed however is amazing news - they were attacked by an unknown group of kerbals that ambushed them from caves near the landing site!
Kerbal Space Agency
@KSA_MissionCtrl
today our astronaut crew achieved an important milestone in their training - they have collectively succeeded more times than failed in the capsule simulator. Congrats - keep working hard, space is only getting closer!
Kerbal Space Agency
@KSA_MissionCtrl
furthermore, in the case of this 100km orbit the Block II has enough power on its own to lob the entire Viklun upper stage to that height, so the Viklun only has to start twice in some cases, although it is capable of as many as three restarts (ascent/orbit/de-orbit)
Kerbal Space Agency
@KSA_MissionCtrl
even if we cut the tank size in half, the Block I was unable to make orbit without the payload itself requiring its own engine to complete the burn and we don't want to waste payload mass on more fuel. The Block II will be the only lifter to carry Viklun upper stages
Kerbal Space Agency
@KSA_MissionCtrl
the Mk1 Capsule tips the scale at ~1.5t so it should be able to make a low orbit - we'll have news on that later this week as work is still being done to confirm it's possible. Even if not, we already know we can design satellites massing <1t
Kerbal Space Agency
@KSA_MissionCtrl
we are happy to reveal the blueprint of the complete Viklun upper stage for the Ascension Mk1-II lifter! Two images after shows it modeled to place a 1t payload into a circular 40° inclined 100km orbit with a hefty error margin of nearly 700m/s of Δv to spare
Kerbal Space Agency
@KSA_MissionCtrl
final assembly for next week's launch is well underway on the Ascension side of the VAB with the lifter in place for stacking the capsule later this week after it finishes integration. Wondering where the RCS blocks went from last week's capsule test? Wonder no more!
Kerbal Space Agency
@KSA_MissionCtrl
last week's LES pad abort test went off perfectly and ends the test series. Ascension team is currently considering the need for an ascent abort test as well, which would finally discard the beat-up test capsule since it can't operate in space anymore anyways
Kerbal Space Agency
@KSA_MissionCtrl
end of the week is here at last! Catch anything you may have missed in our Ops Summary: kerbalspace.agency/?p=8916 we suggest all our rocketry crews get some rest this weekend - launch campaign for the next Ascension mission kicks off in earnest next week!
Kerbal Space Agency
@KSA_MissionCtrl
preliminary review of telemetry data and video footage confirm the test went off as planned. You can barely see the difference in motor ignition but it's there. LES tower impacts first (with unspent kick motor making a bit of boom) followed by heat shield after full chute deploy
Kerbal Space Agency
@KSA_MissionCtrl
recovery crews report the capsule has landed without issue around 800m from the launch pad. Flight data shows it reached a height of just over 300m, nearly as high as the last test. Kerzzah! This fine-control over the LES motors is just the beginning of our plans...
Kerbal Space Agency
@KSA_MissionCtrl
pad abort test in 5 minutes! A single push motor will light off just 2 milliseconds before the other three to tip the capsule over slightly before it flies up and away. At least, that is the plan. Stand by...
Kerbal Space Agency
@KSA_MissionCtrl
30 minutes to pad abort test. Rocket was rolled out and mounted the previous day cycle, Monolith is chilled and capsule is powered up. FD Lanalye and her team are beginning their system checks while pad crews close out and pull back to prep for recovery operations
Kerbal Space Agency
@KSA_MissionCtrl
Lead Engineer Simon has reported the test rocket completed integration in the VAB today and has been laid horizontal on the carry vehicle for rollout tomorrow after 2nd sunrise. Pad abort remains on schedule for 20:00 UTC

the shake table that R&D is working on will be used to help certify rocket payloads for flight by subjecting them to the vibrations they will undergo during launch. Small & simple payloads launched so far not as easy to disrupt as larger more complex satellites of the future
Kerbal Space Agency
@KSA_MissionCtrl
lunchtime at KSC is a great chance for all depts to mingle & share stories - helpful like in the case of the engineering labs realizing the groundquake picked up by their instruments was actually the shake table down the hall at R&D, which suffered a damper failure

@KSA_MissionCtrl
Head of Finances Mortimer confirms we had another profitable month in March, although just barely and only because Genesis is still largely on hold until C7 gets its affairs in order and spending on Dhumla testing is nonexistent. Full report: docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
K2-X engine explosion investigation remains ongoing and confirmation has just been released that it was definitely the engine that blew up, not the fuel tank so use of the engine for kerbed flight remains restricted until the investigation completes its work
Kerbal Space Agency
@KSA_MissionCtrl
originally designed as an 0.625m engine, it was scaled up to 1.25m for use with Ascension and instead became the precursor for the 0.625m Ospray engine planned for Progenitor. The enlarged design puts out 68kN of thrust with an ISP of 360
Kerbal Space Agency
@KSA_MissionCtrl
the C7/Airship fiasco has thrown global shipping into a bit of disarray and delayed the arrival of our 2nd stage vacuum engine but the Viklun from Bluedog Design Bureau is at last in the VAB undergoing initial checkouts! It will hopefully power 1.25m payloads into orbit
Kerbal Space Agency
@KSA_MissionCtrl
test capsule is being re-integrated today with the dummy heatshield (now rather beat up but still usable) and LES tower to prep for its third pad abort test at the end of the week, currently targeting 20:00 UTC
Kerbal Space Agency
@KSA_MissionCtrl
we don't mess around when it comes to calculating launch profiles for our rockets. How do we get the precise surface area that will be encountering the atmosphere on ascent? A new KSPTOT wiki article reveals all: github.com/Arrowstar/kspt…
Kerbal Space Agency

another week behind us, catch up on all that happened with additional details via our Ops Summary: kerbalspace.agency/?p=8899 have a relaxing weekend, everybody!
Kerbal Space Agency
@KSA_MissionCtrl
next week we will have another LES pad abort test to see if we can still send the capsule off the flight path of the rocket or to the side while on the pad if the kick motor fails. In that scenario, one of the push motors will fire off a split second earlier than the others
Kerbal Space Agency
@KSA_MissionCtrl
full video of yesterday's LES pad abort test now available. Data review shows everything worked perfectly. The LES will be integrated for the next Ascension launch even tho it will be uncrewed to ensure it doesn't upset the rocket's flight youtube.com/watch?v=zubZ6G…
Kerbal Space Agency
@KSA_MissionCtrl
the new Mk1 capsule has arrived on schedule, which means the next Ascension Mk1 launch also remains on schedule, still slated for no earlier than 4/16. We will be able to lock in a launch date next week once the capsule is through preliminary inspections
Kerbal Space Agency
@KSA_MissionCtrl
full video with additional angles will be posted tomorrow but here's a look at the capsule flying up into the air and nearly out of sight into the distance from the launch tower camera. Now that's more like it!
Kerbal Space Agency
@KSA_MissionCtrl
recovery crews confirm the capsule is in good shape and work has begun to get everything back to the VAB. Launch control team is busy already reviewing video footage and telemetry data - we'll get a clip up later today
Kerbal Space Agency
@KSA_MissionCtrl
success! The capsule flew to a height of 384m before coming down under 3 good chutes to land almost 700m from the launch pad. Almost flipped over once but after LES tower jettison aero forces turned it bottom-first along its trajectory for clean chute deploy & heat shield drop
Kerbal Space Agency
@KSA_MissionCtrl
5 minutes! Unlike our first test, the adjusted LES tower should now angle the capsule up and away a good distance from the rocket as the kick motor at the top of the tower will not fire with the same duration as the 4 push motors at the base. Stand by!
Kerbal Space Agency
@KSA_MissionCtrl
10 minutes to test! Weather remains green, Flight Director Lanalye and her launch team are back to work arming the abort system and finalizing the capsule for its ejection from the stack
Kerbal Space Agency
@KSA_MissionCtrl
30 minute to LES pad abort test, rocket is online and all systems are nominal. Team is now holding to ensure weather continues to cooperate. Pad crews are finishing securing the rocket and clearing back to prepare for recovery operations
Kerbal Space Agency
@KSA_MissionCtrl
sun is rising and preparations are underway to begin powering up the capsule and run through pre-test checks. Monolith chilldown was begun earlier and while we still have some time buffered in to account for any serious weather, we don't expect any
Kerbal Space Agency
@KSA_MissionCtrl
Mk1 lifter and capsule have successfully been rolled out and mounted on the launch pad, configured the same as last time with the single umbilical connected to provide power to the capsule for the test, which remains on schedule for later today @ 19:50 UTC
Kerbal Space Agency
@KSA_MissionCtrl
Ascension LES pad abort test is now scheduled for tomorrow, 19:50 UTC. Rocket was moved out to the pad however a mechanical issue arose with the arm that lifts the rocket vertical. After trying to fix it out on the pad the vehicle has now been rolled back to the VAB for repairs
Kerbal Space Agency
@KSA_MissionCtrl
we were unable to get the Mk1 rocket/capsule out to the pad this day cycle due to adverse weather conditions. The pad crew is capable of mounting at night and as soon as conditions improve they will begin work to get everything set up for a test later today closer to 3rd sunset
Kerbal Space Agency
@KSA_MissionCtrl
Mk1 capsule test article was re-integrated with the dummy heatshield and fixed Launch Escape System tower yesterday. Today it is being re-mounted atop an Ascension Mk1 lifter. All remains on schedule for another pad abort test of the LES tomorrow at 19:30 UTC

@KSA_MissionCtrl
break time for the astronauts? Hardly! Bill will be helping to fix it, Bob will be helping to re-write the sim software while Jeb & Val plan a Deuce flight for tomorrow to take care of a contract that's been laying in wait since the C7 Aerospace fallout
Kerbal Space Agency
@KSA_MissionCtrl
one of Flight Director Lanalye's sim scenarios got a bit *too* realistic in shorting out part of the capsule console and actually damaged some of the instruments, necessitating repairs that will last at least two days
Kerbal Space Agency

operations are in a bit of a lull right now but still there are things to report in our weekly Ops Summary: kerbalspace.agency/?p=8859 everyone have a happy weekend!
Kerbal Space Agency
@KSA_MissionCtrl
the plan of course is to return all RTGs under chute at the end of the satellite's mission for reuse or at the end of their lifespans but we have to also be prepared for a worst-case scenario where a planned recovery fails & the satellite crashes into the surface instead
Kerbal Space Agency
@KSA_MissionCtrl
while the RTG casing has been proven to contain the radiation, one of the Mk7's first missions will be to launch a dummy satellite which will be crashed down onto Kerbin to assure that the RTG can withstand the impact and not leak any radioactive material
Kerbal Space Agency
@KSA_MissionCtrl
kuudite-powered radioisotope thermoelectric generators, which have been under development since late 2017, have proven to be reliable sources of energy that could power our first satellites, although the Progeny Mk7 will be needed to finish qualification
Kerbal Space Agency
@KSA_MissionCtrl
although not capable of flight, the test capsule can still work for another LES pad abort test. It will be re-integrated with the fixed LES tower and mounted to a different Mk1 lifter (we have 3 other ones ready). Re-test will take place next week on 3/27
Kerbal Space Agency
@KSA_MissionCtrl
Lead Engineer Simon has confirmed the test capsule is no longer structurally fit for flight. New capsule is set to arrive next week, will undergo inspection the following week and then begin integration for flight. Next Ascension Mk1 launch date NET 4/16
Kerbal Space Agency
@KSA_MissionCtrl
LES solid rocket pitch motor atop the tower is confirmed to simply be the same as the push motors, which means the simple fix is to replace the pitch motor on the 2nd LES meant for flight with the proper one and test again, altho whether the capsule can be reused still a question

@KSA_MissionCtrl
learn more about today's semi-successful launch escape system pad abort test and more happenings from this past week in our Ops Summary: kerbalspace.agency/?p=8845 Sadly yes, this will delay getting a kerbal aboard for a sub-orbital flight
Kerbal Space Agency
@KSA_MissionCtrl
chutes normally deploy in about 8sec but they are reefed to allow safe deceleration at transonic speeds. This low in atmo & moving slower when allowed to deploy fully without reefing they can arrest descent in just over 2sec - it was barely enough to spare the capsule!
Kerbal Space Agency
@KSA_MissionCtrl
here's how the pad abort test went down earlier today. Poor Bob managed to turn even greener watching it. Greggery the test dummy was aboard and only had to suffer through just under 5Gs of force during the tumble. Capsule flew about 70 meters from the pad
Kerbal Space Agency
@KSA_MissionCtrl
capsule & LES are being moved back to the VAB while pad crews begin to dismount the Mk1 lifter to roll it back to the VAB - the first time we've taken one down after setting it up. Video of the abort test will be posted later today before our Ops Summary
Kerbal Space Agency
@KSA_MissionCtrl
here's an enhanced image from the video footage showing all 5 solid rocket motors on the LES firing very late into the abort burn. This is improper behavior indicating a design flaw - top motor only supposed to fire a short duration to tilt capsule away from rocket
Kerbal Space Agency
@KSA_MissionCtrl
more information coming in now that pad workers have reached and inspected the capsule. Lead Engineer Simon reports heavy damage to the exterior that likely renders it unfit for future missions. LES tower is thankfully mostly intact so we can study what went wrong with it
Kerbal Space Agency
@KSA_MissionCtrl
test complete! That - did not quite go exactly as planned. FD Lanalye is still having her team do a quick review of video & telemetry data to determine exactly what went wrong but at least we can report the capsule appears to have somewhat survived
Kerbal Space Agency
@KSA_MissionCtrl
5min until test. LES is armed for abort procedure and flight computer is standing by for the command to initiate. If all goes well the capsule will be rocketed away on an arc that takes it clear of the launch pad, then deploy chutes, drop the heat shield and land
Kerbal Space Agency
@KSA_MissionCtrl
15min until test! Weather remains stable, final arming and system checks are underway now in launch control under the watchful eye of Flight Director Lanalye. Astronauts are also here to witness what they could possibly have to endure someday (hopefully never though)
Kerbal Space Agency
@KSA_MissionCtrl
all systems looking good, now just over an hour away from test time we are holding and still making sure no storms are forming. Final test preparations will commence at 18:45 UTC if weather conditions remain stable
Kerbal Space Agency
@KSA_MissionCtrl
LES test proceeding as scheduled. Monolith temple chilled - once stable temps confirmed the rocket will be powered on to load test routines and prepare the systems for action. Pad crew is pulling back to 100m and standing by for recovery after the test
Kerbal Space Agency
@KSA_MissionCtrl
with the sun fully set, the Monolith temple chill down has begun. We considered leaving it alone to see if storms formed as this is a different rocket design but being already behind schedule we want to avoid further delays & any damage to the rocket itself from lightning
Kerbal Space Agency
@KSA_MissionCtrl
we were able to complete rollout of the Ascension Mk1 earlier this day cycle and it is now vertical on the pad. Only the top umbilical is attached to supply power to the capsule, which will be switched on to begin preflight after 17:30 UTC
Kerbal Space Agency
@KSA_MissionCtrl
forecast models are still not very reliable unfortunately and the storm system has moved inland. Pad abort test has been scrubbed for today. We will make another attempt tomorrow with rollout after 2nd sunrise and test scheduled for 19:00 UTC
Kerbal Space Agency
@KSA_MissionCtrl
high winds have prevented us from completing rollout of the Ascension Mk1, mainly the process of lifting the rocket vertical. We should have better conditions later today if a nearby storm system stays out to sea as forecast. New test time is 3/15 @ 00:45 UTC
Kerbal Space Agency
@KSA_MissionCtrl
Ascension engine clamp has been installed out on the launch pad for tomorrow's rollout and pad abort test. Rocket has been loaded up onto the carry vehicle in the VAB. Test is currently scheduled for 18:30 UTC
Kerbal Space Agency
@KSA_MissionCtrl
Jeb boasted he's been simming so hard he could do a mission blind folded. Flight Director Lanalye told him to prove it. It did not go well. Worse - she now has new ideas for impaired vision emergency practice scenarios
Kerbal Space Agency
@KSA_MissionCtrl
post-launch operations wrapping up, which included hauling the Progeny launch base back to the VAB so tomorrow pad workers can install the Ascension engine clamp in its place. MSV Tongjess returned the splashed down weather balloon & has returned to port in Umbarg
Kerbal Space Agency
@KSA_MissionCtrl
we have liftoff!! Lower 0.625m booster has ignited with an intial force of 67.2kN to push the rocket off the pad at ~4Gs. It will burn for ~34 seconds and stage a second later. The rocket will then coast until its nose drops 1.5° before igniting the 2nd stage SRB
Kerbal Space Agency
@KSA_MissionCtrl
recap and learn more about the events from this past week via our Ops Summary, including the return of a Desk Note now that @DKerman_KSA is back from his trip to Sheltered Rock kerbalspace.agency/?p=8811
Kerbal Space Agency
@KSA_MissionCtrl
additionally of note, the heat shield seen in the last posted image is a mock-up, since it will be dropped shortly after chute deploy during the LES pad abort test. The real one will be attached prior to the actual launch
Kerbal Space Agency
@KSA_MissionCtrl
there are no nose thrusters hidden under the escape tower, the capsule can pitch/yaw/roll just fine with the thrusters mounted near the base, and while it can only thrust in one direction, it can re-orient itself to push along whatever vector is needed
Kerbal Space Agency
@KSA_MissionCtrl
up it goes! The Mk1 capsule begins integration today with the Ascension Mk1 lifter while the next Progeny Mk6 waits in the background for its launch attempt the following week. Note the RCS thrusters, which we neglected to include in the infographic released last month
Kerbal Space Agency

Kerbal Space Agency
@KSA_MissionCtrl
It was actually scheduled for 3/7 but yes the Ascension schedule will be pushed back as well - it is taller than the launch towers and we don’t want to risk a storm developing if it is brought out to the pad and switched on twitter.com/rocketbeing/st…
Kerbal Space Agency
@KSA_MissionCtrl
monolith temple A/C install was completed over the weekend however the system broke down shortly after it was turned on. Contractor has looked into the issue and says it will take the remainder of the week to repair. New L-0 for next launch is now 3/12 @ 18:10 UTC
Kerbal Space Agency
@KSA_MissionCtrl
Ops Director @DKerman_KSA has been mostly stone-walled in Sheltered Rock attempting to get some answers on the whole C7 debacle. Learn more along with what else went on this week in our Ops Summary: kerbalspace.agency/?p=8798
Kerbal Space Agency
@KSA_MissionCtrl
work on the next Ascension Mk1 and Progeny Mk6 rockets proceeding apace in the VAB. Lead Engineer Simon has reported all remains on schedule for our next launch attempt the following week: ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
spending the last two days searching up to several hundred meters from around the test stand to collect all the debris, the HAB is being used during its downtime to hold everything and allow investigators to rebuild things and conduct their review of the engine explosion
Kerbal Space Agency
@KSA_MissionCtrl
today's accident with the 1.25m test stand will not affect Progeny Mk7 development, as its new vacuum engine is small enough to test at Rockomax's own facility. The Viklun 1.25m vac engine will simply be tested during unkerbed flight as it is far & away by the time it ignites
Kerbal Space Agency
@KSA_MissionCtrl
all previous engines passed static fire testing without issue & Ascension Mk1 capsule test flights are still GO. However, until the investigation concludes no kerbed flights will be conducted. Astronauts are bummed, but everyone understands crew safety is paramount
Kerbal Space Agency
@KSA_MissionCtrl
all safety protocols were followed & no one was nearby when the incident occurred. Test stand will be rebuilt after a thorough investigation looks over it and the remains of the engine as well as test data to attempt to determine what went wrong
Kerbal Space Agency
@KSA_MissionCtrl
earlier today before 2nd sunset the latest K2-X engine was undergoing a routine ascent simulation static fire on our test stand. Some fault during testing led the engine to explode, causing irreparable damage to the test stand and rattling the windows of the R&D complex
Kerbal Space Agency
@KSA_MissionCtrl
we have learned all we know from the press conference just held: kerbalspace.agency/?p=8781 this will have an immediate impact on fixed-wing flight here at the Cape, however the long-term impact is still largely speculative since more details have yet to be released by authorities
Kerbal Space Agency
@KSA_MissionCtrl
BREAKING: KNN has reported that the entire executive division of C7 Aerospace has been arrested and the government is launching a full scale investigation into the company. We are partners with them and have no idea what is going on - this is all news to us!!
Kerbal Space Agency
@KSA_MissionCtrl
a visitor today asked their guide a reasonable question: why haven't we used the Ascension Mk1 Block II to try to make orbit? It would certainly get the rocket moving faster, but the real issue is following a proper ascent profile - it can't steer any better than a Block I
Kerbal Space Agency
@KSA_MissionCtrl
our week of operations has concluded, be sure to check out our Weekly Ops Report to get all the information on what has transpired: kerbalspace.agency/?p=8769 (BTW new altitude record is 8.683km ASL)
Kerbal Space Agency
@KSA_MissionCtrl
assuming the next Progeny Mk6-I launches on time we will have the Ascension Mk1-I out on the pad two days later for its LES test on 3/7. If that goes well, the capsule LES will be replaced & capsule re-integrated w/rocket over the following week for launch on 3/14
Kerbal Space Agency
@KSA_MissionCtrl
Lead Engineer Simon reports the horizontal fins for the next Ascension Mk1 lifter have been removed and meticulously replaced at a 5° angle to cause the rocket to naturally nose downwards. Seems slight, but these fins are quite large & will have a noticeable effect
Kerbal Space Agency
@KSA_MissionCtrl
astronauts are setting up for another grueling day of simulation runs. The only good news is that FD Lanalye has begun to run out of ideas for new scenarios, allowing the crew to slowly work towards a better success/fail ratio thx to encountering similar problems more often
Kerbal Space Agency
@KSA_MissionCtrl
additional Ascension news includes a look at the complete assembly of the Mk1 capsule. Decision has been made for the Launch Escape System to undergo a pad abort test prior to the next Ascension launch, which will push it back closer to the middle of March
Kerbal Space Agency
@KSA_MissionCtrl
both of the K2-X engines that were delivered back at the end of Jan have been successfully static-fired on our test stand and are finishing up their refurbishment & integration into the Ascension Mk1 lifters. 5th engine received yesterday will be tested next week
Kerbal Space Agency
@KSA_MissionCtrl
if the K2-X falls short of our orbital needs, we will have to wait about a year for a new 1.25m lifter engine to allow some design iteration with the gimbal system on the smaller Progeny Mk7 engine. Still, it can continue to support sub-orbital capsule flights
Kerbal Space Agency
@KSA_MissionCtrl
our initial order of 5 K2-X lifters for the Ascension Mk1 has been satisfied today with the final engine delivery. We will soon have 3 more on the way as well. Additional orders will depend on the success of the upcoming 2nd-stage engine orbital test flight later this year
Kerbal Space Agency
@KSA_MissionCtrl
astronauts took time from their busy schedule to visit a school in Umbarg as part of their educational outreach. One kerbling asked what happens if you peed in your space suit. Bob promised him he would find out. Such bold frontiers to explore!
Kerbal Space Agency
@KSA_MissionCtrl
before we can announce the date of the next Ascension mission we have to wait for the VAB crews to complete their modifications to the rocket fins for the next vehicle. Lead Engineer Simon reports they hope to wrap things up by the end of the week
Kerbal Space Agency
@KSA_MissionCtrl
the Ascension Mk1 capsule has been flight certified! The current one has undergone too many tests to safely carry an astronaut, but we can still use it for the next Ascension flight as a test vehicle. A new capsule for the first crewed flight is currently under construction
Kerbal Space Agency
@KSA_MissionCtrl
ever since the Mk6 debuted a year ago Progenitor has been cranking away at R&D and accumulating design goals for the Mk7. Like all its forebears, it will be a pathfinder for new technologies, most of which will make their way onto Ascension rockets. Here they are:
Kerbal Space Agency
@KSA_MissionCtrl
this flight analysis was also conducted in part with the Progenitor team, who were working on the finishing touches to the Progeny Mk7 design when Ascension made some requests for technology they'd like to see prototyped. Stay tuned for details next week!
Kerbal Space Agency
@KSA_MissionCtrl
the results are finally in from last month's Ascension Mk1 flight and there's still a lot of work to be done since much of the data was inconclusive in determining key aspects of the flight profile that we plan to send kerbals along kerbalspace.agency/?p=8614
Kerbal Space Agency
@KSA_MissionCtrl
despite the recent ups and down our rocket program has been having we're still seeing growing interest in the commercial sector and Head of Finances Mortimer is already drawing up contract paperwork. We hope to make some exciting announcements soon!
Kerbal Space Agency
@KSA_MissionCtrl
Bob deserves to be embarrassed for his performance so far, but we’ll save him total mortification and keep the numbers private. Unsurprisingly Jeb & Val are duking it out for the top spot. Currently Val has a slight lead
Kerbal Space Agency
@KSA_MissionCtrl
capsule simulator has gotten a lot less buggy and faulty, meaning more training runs for the astronauts to do battle with Flight Director Lanalye, who has been coming up with increasingly more creative ways to kill them. So far she's still winning 248 failures to 129 successes
Kerbal Space Agency
@KSA_MissionCtrl
our brief unexpected foray out into inter-planetary space found much less radiation than predicted, which is great news. How far our magnetotail stretches in the opposite direction is still unknown, but could potentially cross Mun orbit
Kerbal Space Agency
@KSA_MissionCtrl
second belt cannot be avoided when leaving Kerbin orbit, but it is not as dense or as wide as the inner belt so can be traversed with minimal shielding as vessels will be traveling through at high velocities
Kerbal Space Agency
@KSA_MissionCtrl
the prominent journal Science Source has published our paper discussing the radiation data from the recent Progeny MK6-II launch. The highlights are the confirmation of the second outer radiation belt and discovering the sunward boundary of the magnetosphere!

Head of Finances Mortimer has our books balanced for January. We expected a loss thanks to the Dhumla testing but the failure of the Progeny Mk6-I mission was a big blow. Not a strong fiscal start to 2019... docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
on a related note, Head of R&D Wernher von Kerman is *not* happy with Head of Finances Mortimer and the cuts he made to our R&D budget this year, so we hope to get him some operational test data soon because, well - an unhappy Wernher is not a thing you want around...
Kerbal Space Agency
@KSA_MissionCtrl
all the science instruments we'll be including on the Extremis probes are ready to be tested in space, we're just waiting on a good means of getting them up there. Primary vehicle would be Ascension but can't rule out a future Progenitor rocket either twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
Ascension capsule has completed its test regimen and is undergoing final certification review, which will take about 2 weeks as engineers look over the copious amounts of data collected, as well as conduct one last thorough inspection of the capsule itself
Kerbal Space Agency
@KSA_MissionCtrl
head on over to bit.ly/AFCS_ChangeLog to check out the latest updates to both the flight computer and mission software. We are excited to be using the hibernation capabilities for the first time on this launch, a vital test for future unkerbed orbital missions

@KSA_MissionCtrl
2 more K2-X lifter engines have arrived to complete some add'l Ascension Mk1 boosters next month. With 4 remaining in our current inventory the plan right now is to allot 2 for more sub-orbital capsule testing, 1 for a kerbed flight & 1 for 2nd stage vac engine orbital flight
Kerbal Space Agency
@KSA_MissionCtrl
PLOT ALL THE THINGS!! Ascension flight analysis is well underway and the team has plenty of things to look at when comparing the actual flight data to the planned flight data. Numerous deviations are evident and all need to be explained
Kerbal Space Agency
@KSA_MissionCtrl
astronauts have begun their capsule sim training - or rather, have begun figuring out what's wrong with the capsule simulator training program. This is supposed to be easy?? We think not. Jeb has found the most problems so far. He says it's in his nature to break things

photo from this week's launch as the rocket passed through 25km, looking back towards KSC, nearly hidden by the expanding exhaust plume. This is well above the thickest part of the atmosphere, seen as a thin layer separating the horizon from the blackness of space
Kerbal Space Agency
@KSA_MissionCtrl
what a long and busy week! So much to talk about in our weekly ops report - stop by even if you've seen all our tweets as we do like to include additional information here: kerbalspace.agency/?p=8434
Kerbal Space Agency
@KSA_MissionCtrl
here's the full video of the payload separation from yesterday. So smooth! A very small initial force was given to the payload at separation in case the RCS system failed & the 2 pieces would have eventually drifted far enough away by the time of re-entry youtube.com/watch?v=bqa7Wk…
Kerbal Space Agency
@KSA_MissionCtrl
telemetry data recorded during yesterday's flight is now available. For the first time we will be comparing this to data projected by the Launch Vehicle Designer tool to see how our planned launch matched up with the real one docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
we have two celebrations going on today - one in the VAB for the success of today's mission and another in the HAB for the completion of the Dhumla, which will be deployed tomorrow to begin its ground testing ahead of flight trials
Kerbal Space Agency
@KSA_MissionCtrl
we should have the payload back by tomorrow, then it will likely be at least 2 weeks of post-flight analysis - the trajectory compared to LVD, how the heat shield handled re-entry, inspection of the RCS system, review of tlm data, review of software issues... lots of work!
Kerbal Space Agency
@KSA_MissionCtrl
great news - payload was found buried 1/4 of a meter up its nose into the dirt of a hillside - which means those nose thrusters are probably a write-off but at least it didn't roll down the slope and the rest is in great shape! Mission success! KERZZAH!! 🎉🥂✨
Kerbal Space Agency
@KSA_MissionCtrl
airship is en-route, radio beacon still being received so it landed intact and in sight of Ockr aerial. While we await word on the overall condition of the payload, post-launch operations continue, which also include removal of the engine collar to get set for next week's launch
Kerbal Space Agency
@KSA_MissionCtrl
an airship was on standby & is being dispatched to the landing area. Chutes were mounted on the bottom to flip the payload over to land nose first, allowing a faster descent using smaller chutes & still protect the heat shield from damage so it can be inspected post-flight
Kerbal Space Agency
@KSA_MissionCtrl
full chute deploy confirmed! We did suffer a flight computer crash shortly after regaining comms but chutes have a backup air pressure sensor for deployment & payload still transmitting a signal if not data so we can see speed change thanks to doppler effect
Kerbal Space Agency
@KSA_MissionCtrl
testing was completed in time and with enough propellant remaining to point retrograde for the heat shield to face the atmosphere. Payload has just come out of plasma blackout - it is falling well short of the intended landing zone but thankfully in a relatively flat area
Kerbal Space Agency
@KSA_MissionCtrl
we're through apokee and on the way back down, control testing going well. Two control models are being put through pointing the rocket along the 6 main axis of orbit. Coarse control always uses full thruster power while a Fine control model adjusts the thruster output as needed
Kerbal Space Agency
@KSA_MissionCtrl
thankfully the fix was simply to cut the throttle. Time in space is already counting down, approaching 255km apokee in <2min and there are lots of tests that need to be run before we hit the atmosphere ~5min after that. Hopefully we didn't use up too much propellant already
Kerbal Space Agency
@KSA_MissionCtrl
controllers are working an issue. RCS was supposed to stop thrusting after 10s but is still pushing forwards. Yes, we did try to turn it off and back on again. It looks like we may need to send up some new commands - careful! We don't want to crash the system...
Kerbal Space Agency
@KSA_MissionCtrl
beautiful confirmation of separation from the booster camera, which has a power/data cable hooked to the payload to give us this view for a few seconds before it gets pulled out. That is Eve just to the right and Jool up in the right corner
Kerbal Space Agency
@KSA_MissionCtrl
MECO right on schedule although we were 8km lower than expected. Having coasted out of the atmosphere the payload has been decoupled and will use its RCS thrusters to push it away from the fuel tank. Controllers will then begin a series of control tests
Kerbal Space Agency
@KSA_MissionCtrl
rocket is through Max Q & throttling back to reduce heating in the upper atmosphere, chamber pressures are nominal. No rolling showing up in tlm data but pitch controls are at full deflection unable to maintain desired pitch over rate. We are heading up steeper than planned
Kerbal Space Agency
@KSA_MissionCtrl
main engine ignition, throttle up and LIFT OFF for the 3rd Ascension Mk1 Block I, aiming to pave the way for sub-orbital kerbed spaceflight! Rocket has cleared the tower & guidance has kicked in, throttling up to full and pitching over towards the horizon, aiming for 70° by 10km
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] the flight computer will perform these final steps to ensure the rocket is ready for ascent when the engine clamp lets go at T-0. Any abort after T-30s final primary station poll will most likely be automated but controllers can call a hold all the way up to launch
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] rocket has entered the terminal countdown phase, where the flight computer takes control. Service tower arms have disconnected and swung away leaving the rocket running on internal power with RF comms signaling Mission Control to let us know all is still well
Kerbal Space Agency
@KSA_MissionCtrl
[L-3m] tank pressurization has begun to ensure the rocket is able to stand on its own atop the engine collar once both the service tower arms have retracted. Helium may one day be used when we really need to save weight, but for now we need to save cost
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] Final readiness polls complete: Wx: GO; Range: GO; Flight: GO; Tracking Station: GO; Downrange Tracking: GO; Ops Director: Launch permission granted! 🚀GO ASCENSION🚀 FTS on internal power, service tower booms unlocked to prep for retraction, AFCS ready for terminal count
Kerbal Space Agency
@KSA_MissionCtrl
the lack of full tanks led to some issues during the WDR earlier this week getting them up to flight pressure in time for launch during the final seconds of countdown and is why the launch was delayed so we could improve the pumping system in the service tower
Kerbal Space Agency
@KSA_MissionCtrl
[L-13m] a truck still hooked up to the service tower has begun to pump nitrogen into pressure vessels on the rocket, which will then be used to pressurize the main tanks during the flight. Late onload protects pad workers from any rupture and explosion
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] RSO has closed the range - pad is clear, waters are clear, airspace is clear. Rocket has been ARMED for ignition and Flight Termination System is ACTIVE. Final checks on the primed rocket underway that couldn't be performed prior to this point
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] it is literally the crack of dawn (Eve shining above) right now as we move into final countdown procedures with a GO from the weather team - all surface weather constraints are showing <5% chance of violation over the coming hour. Be nice, @upperlevelwinds!
Kerbal Space Agency
@KSA_MissionCtrl
[L-45m] pad has been evacuated of all crew, rocket remains healthy & ready to go. Sheltered Rock & Ockr comm relays have been established. Comms with MSV Lymun offshore east of Ockr have also been received. Full launch rehearsal getting underway to ensure all systems configured
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h20m] Hoodall has also launched our weather balloon due to current wind conditions - it will be either recovered by the ship if it lands back at sea or UTVs are standing by to track it down overland. Upper-level wind report will arrive just prior to final polls
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h30m] FD Lanalye reports issues board remains clear, all systems are nominal. Ground crew moving back in to ensure rocket is secure before everyone pulls back. Flight Control now moving to external tasks such as range setup - today's monitor will be MSV Hoodall
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h55m] ground crews have cleaned up after fueling & secured the service towers. Pad evacuation underway ahead of engine and ignition system checks. Fuel levels are still being monitored for leaks, but so far no evidence seen. QRT sheltering in nearby bunker
Kerbal Space Agency
@KSA_MissionCtrl
we are happy to be welcoming back the crowds for another launch, but please remember if you're outdoors hearing protection is REQUIRED. KSC employees will be on the lookout - anyone caught without it will be banned from future launches. Same goes for leaving designated viewing areas!
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h47m] wrapping up early, still after two trips each for the fuel trucks, the tanks are topped off with a total of 5.95t of fuel, or 85% of full capacity. This will allow us to expend all the fuel on our trip to space and still stay within mission constraints
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h15m] after initialization the rocket was configured to begin tanking operations. Similar to our last launch, as the sun sets liquid fuel and oxidizer trucks take turns hooking up to the service tower to pump fuel aboard the rocket. Ground crews have the GO to begin
Kerbal Space Agency
@KSA_MissionCtrl
all the control files contain just 1-2 lines of code, but we call a file instead of entering commands directly because the code in the files are run-checked for errors. Much easier for the flight computer to spot & handle a bad filename instead of bad code w/o crashing
Kerbal Space Agency
@KSA_MissionCtrl
rocket is initialized, flight code has been onloaded to the flight computer, along with the various control commands that will be used once in space to test the new RCS system. You can check out the changes and new command additions via bit.ly/AFCS_ChangeLog
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h30m] flight team is ready, ground crews are ready and weather kerbs have finished analyzing the various regional reports and consulted earlier forecasts to give us a GO to proceed into preflight! Surface conditions around launch time look 90% favorable
Kerbal Space Agency
@KSA_MissionCtrl
finally, we know from bit.ly/ProgenyMk6B1-5 that this trajectory can go as high as nearly 500km and still not encounter the radiation belt, making it a good option for future sub-orbital kerbed missions. A radiation instrument is onboard though just to make sure
Kerbal Space Agency
@KSA_MissionCtrl
launching again on a 45° azimuth will take the rocket over Sheltered Rock & Ockr for downrange signal reception, which will allow it to travel the farthest distance and spend the most time in space while still coming down (hopefully) over smooth terrain or water
Kerbal Space Agency
@KSA_MissionCtrl
here's another look at the mission and its goals. Three main objectives for this flight are:
◾ gathering ascent data to compare to LVD predictions
◾ testing the reaction control system & guidance
◾ testing the heat shield ablative surface

after a long day of work resolving GSE issues we are happy to say that all is finally 🚀GO FOR LAUNCH!🚀 It's going to be an early day tomorrow, with pre-launch operations kicking off at 11:53 UTC. Everyone get some rest!
Kerbal Space Agency
@KSA_MissionCtrl
we've isolated the problem with the service towers and a fix is imminent. Weather forecast has been delivered and tomorrow is looking better anyways, with only 26% chance of violation. We'll conduct another WDR later today to confirm launch readiness
Kerbal Space Agency
@KSA_MissionCtrl
Mk1 capsule is undergoing more trials this week, over land this time. This includes another landing and recovery test under chute. Here is what the triple canopy looks like. Not only does it provide redundancy, but also makes the capsule easier to spot on descent
Kerbal Space Agency
@KSA_MissionCtrl
we've confirmed that it's not the rocket that is the problem, which is good news because we can fix the service tower while the rocket remains on the pad, so less time will hopefully be needed to get to launch readiness. Technicians are still closing in on the issue

@KSA_MissionCtrl
today the Ascension Mk1 was rolled out, installed into its engine clamp & hooked up to the service tower. A wet dress rehearsal was carried out but tank pressurization was unable to reach flight levels. We are still troubleshooting. Launch is now targeting 1/24 @ 16:13 UTC
Kerbal Space Agency
@KSA_MissionCtrl
weather for tomorrow's launch looking good at only 40% chance of violation mainly from the possibility of overcast skies. We prefer not to shoot through clouds - yes there are minor technical reasons but mainly it's so we can get good visual tracking for post-launch assessment
Kerbal Space Agency
@KSA_MissionCtrl
we never did figure out why our last rocket wanted to roll, so Simon and his team took extra care in assembling these ones - they have an assembly paper trail a kilometer long. If anything abnormal shows up in this launch, we can trace it back if it's a build issue
Kerbal Space Agency
@KSA_MissionCtrl
Lead Engineer Simon has reported the Ascension Mk1 is all closed out and ready to head to the pad early tomorrow for another full day of checks ahead of launch on Wed. We will also have a better idea tomorrow what the weather will be like
Kerbal Space Agency
@KSA_MissionCtrl
wet & dreary weather at the Cape throughout today - bring the rain gear if you've got a tour booked! This system should definitely move on before launch later this week but we can't yet forecast what might come after it by then
Kerbal Space Agency
@KSA_MissionCtrl
one launch week down, two more to go! We have more details on what went down this past week over at kerbalspace.agency/?p=8347 have a nice weekend, everyone!
Kerbal Space Agency
@KSA_MissionCtrl
astronauts will be conducting their final day of sea exercises with the Mk1 capsule today. We'll have more details in our Ops Report later. Next week the capsule will undergo similar exercises over land
Kerbal Space Agency
@KSA_MissionCtrl
@starseeker8749 you mean the yellow protrusions of the test mass? Just generic hard points. We are using them for the RCS thrusters but they could be used for strut attachments if extra reinforcement between it and the lift stage was needed, or maybe something mounted atop the test mass
Kerbal Space Agency
@KSA_MissionCtrl
the NRAP test weight has arrived to be integrated, which will complete the vertical stacking of the rocket. It has been designed to mimic the mass & size of the Mk1 capsule, and will test two important new technologies - a heat shield & reaction control system (RCS)
Kerbal Space Agency
@KSA_MissionCtrl
successful test firing today of the second K2-X engine. We will have 2 more delivered at the end of the month and our last one in February. The other engine has already been integrated into the Ascension Mk1 rocket set for launch next week
Kerbal Space Agency
@KSA_MissionCtrl
crews will bring the capsule aboard and further exercises will be conducted after the Progeny launch with the astronauts taking turns being loaded into the capsule on the deck then extricated while afloat under various simulated conditions, such as injuries, deflation, etc
Kerbal Space Agency
@KSA_MissionCtrl
recovery teams have reached the capsule after it splashed down and automatically deployed its built-in float collar, which will rest underneath the heat shield that would have by now been jettisoned after the chutes were deployed
Kerbal Space Agency
@KSA_MissionCtrl
chute deployment confirmed! A triple canopy has opened above the capsule, providing redundancy in the event of a chute failure. The capsule can tolerate a landing with just one chute, although the occupant may not escape serious injury even on water
Kerbal Space Agency
@KSA_MissionCtrl
we've had capsule release, it will now undergo a ballistic fall down to just 1.5km before its parachutes deploy to arrest the descent. It won't reach speeds anywhere near what it will on re-entry from space but the lower deployment height will help stress test the chutes
Kerbal Space Agency
@KSA_MissionCtrl
MSV Hoodall arrived yesterday to support today's launch, but since it has been delayed Hoodall will be taking the Ascension capsule out for its first sea trial this day cycle. Similar to tests last year, it will be dropped from 16km and recovered after splashdown
Kerbal Space Agency
@KSA_MissionCtrl
being stuck underground for so long gave society an excuse to develop a new way to mark the passage of time, but we still like to make note of a "kerbolar year" on occasions like today - the start of our 8th trip around the sun since the KSA was founded back in Sep 2016! 🥂🎉✨
Kerbal Space Agency
@KSA_MissionCtrl
oh hey! We're still getting back into the habit of having to write up our weekly operations reports. Even if you don't think you missed anything this week, we also tend to elaborate on various things: kerbalspace.agency/?p=8305
Kerbal Space Agency
@KSA_MissionCtrl
today we got a stripped-down version of the Mk1 command pod that will be integrated into a simulator. All 4 astronauts are lending a hand getting it built while the actual pod prepares for drop testing next week
Kerbal Space Agency
@KSA_MissionCtrl
Ascension team reports the static firing of a K2-X engine earlier today shows good data. It has already been unmounted from the test stand and returned to the VAB to be attached this week to the Mk1 lifter that will go up later this month. 2nd engine will be tested next week
Kerbal Space Agency
@KSA_MissionCtrl
additionally, head over to our website for a press release from the Ascension team with further details on the next Mk1 flight, which will *NOT* be trying to achieve orbit kerbalspace.agency/?p=8387
Kerbal Space Agency
@KSA_MissionCtrl
future launches are not scheduled yet because each rocket's future plans will depend on the outcome of its mission:
Mk6-I: survive re-entry?
Mk1-I: tech demo
MK6-II: useful if expendable?

we didn't have nearly as many photos to sort through this past year as we did at the end of 2017 so we've already picked out our top 100 images from 2018: flickr.com/photos/kerbal_… overall favorite is the Ascension Mk1 going vertical for the 1st time

Head of Finances Mortimer has completed his financial analysis from 2018 and you can see the summary sheet here: bit.ly/2018FiscalSumm…. We have also decided that we will begin accepting donations as a way for the public to lend support
Kerbal Space Agency
@KSA_MissionCtrl
as eager as the astronauts are to train in the capsule for actual recovery events, first up will be Greggery - a test weight fitted w/ sensors to sit in the capsule as it's dropped for recovery testing later this month. Apparently the name is some kind of joke but we don't get it
Kerbal Space Agency
@KSA_MissionCtrl
final day of general staff meetings for all programs. Debates have raged but everyone is still friends so far. Great to see so many opinions and ideas being expressed by team members on the various goals that should be pursued this year
Kerbal Space Agency
@KSA_MissionCtrl
one of the reasons Head of R&D Wernher von Kerman wanted to get back to work so badly is because he says they are close to a breakthrough at last & they've also begun to work on studying the Monolith crystal vein's conductive properties twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
our crew had the whole day to come back but all of them were here early to begin getting organized for their return to active duty. Astronauts have nailed down their training schedule while the Flight Officers have inspected & cleared both aircraft ready for service
Kerbal Space Agency
@KSA_MissionCtrl
operational teams from all our programs will be meeting over the course of this week to review 2018 and solidify plans for 2019. We'll have all the details next week about new launch times as well as any additional 2019 goals we didn't mention in our last tweet
Kerbal Space Agency
@KSA_MissionCtrl
everyone is psyched to get some kerbals into space this year! That's pretty much a definite after capsule is certified - Ascension Mk1 is what we would use and it looks like a solid lifter. Orbit? Well, we have a whole year but we'll have to see how the Viklun performs
Kerbal Space Agency
@KSA_MissionCtrl
🎊🎉 HAPPY NEW YEAR!! 🎉🎊
we hope everyone is having a great holiday and look forward to hitting the ground running tomorrow to begin solidifying our plans for 2019, which is looking to be another exciting year for space exploration 🥂✨

@KSA_MissionCtrl
getting a look at all the launch trajectories was much harder this year given the overall height of the missions & the spread of launch azimuths used, but we did our best. You can always download telemetry for individual flights from the Ops Tracker to graph your own data
Kerbal Space Agency
@KSA_MissionCtrl
the final tally for rocket flights from this past year is in! We did not include the Mk1-B, as that counted for atmospheric flight
Kerbal Space Agency
@KSA_MissionCtrl
the data from tests last week of the Viklun have been transferred in full to Bluedog - it looked good in our analysis! Unless they find anything serious we should have first delivery around March 2019 twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
given the financial struggle we had this year, ending up with a huge loss, Head of Finances Mortimer is going to be looking very carefully at whether it was our fault in over-reaching ambition or more a matter of unfortunate external circumstances (*cough*Monolith*cough*)
Kerbal Space Agency
@KSA_MissionCtrl
this week is administrative-focused, getting everything from this past year organized and filed away for review at the start of next year. We'll have a financial analysis in early Jan but for now the basic report including this month has been released bit.ly/Finances_12-18

2018 operations have officially ceased! We will resume operations on Jan 2nd, 2019. We are very pleased we were able to squeeze in so much this final week, here is one last Ops Summary to close out the year: kerbalspace.agency/?p=8189
Kerbal Space Agency
@KSA_MissionCtrl
all 5 of the Ascension Mk1 fuel tanks have been assembled with fins and control surfaces. 2 of the 5 engines have arrived so they can be integrated next month to prepare for the next set of launches - we are currently aiming for late January
Kerbal Space Agency
@KSA_MissionCtrl
after fit testing last week the astronauts have all been doing basic flight operation exercises in the pod to give all the electrical and computer systems a good work through. Bugs & issues have been noted. Remember - this is looking straight upwards, back to the floor
Kerbal Space Agency
@KSA_MissionCtrl
the Viklun vacuum engine had a successful first run on our test stand today. It is using a bell made for sea-level pressures from which the design team can validate the planned performance of the larger vacuum bell. There will be more static fires throughout this week
Kerbal Space Agency
@KSA_MissionCtrl
we have confirmation from Flight Director Lanalye that all systems are GO over at Mission/Launch Control! Monday will see more drills, flight prep and a Deuce flight for final system checks before repeating the release rehearsal that was interrupted back in August
Kerbal Space Agency
@KSA_MissionCtrl
Flight Director Lanalye and her team are moving back into Mission/Launch Control today, will be spending the rest of the week running drills and tests to ensure all the systems are back to full operational status after the repairs
Kerbal Space Agency
@KSA_MissionCtrl
basic capsule testing for this month is going well, finishing up crew fit tests today. Astronauts have taken turns ensuring everyone can be seated properly inside, can reach all the controls and can be extracted both under their own power and while disabled
Kerbal Space Agency
@KSA_MissionCtrl
that still is too much according to the LVD, but the software is still under development and we will continue to work with ArrowstarTech to ensure what we're doing is giving us the proper result and making sure the software is free of any bugs
Kerbal Space Agency
@KSA_MissionCtrl
working with the new Launch Vehicle Designer from ArrowstarTech, based on previous launch data, we've determined our 1t test weight is just too much mass for the Ascension Mk1 to push into even a decaying orbit. We've talked to the NRAP folks and best they can do is 278kg
Kerbal Space Agency
@KSA_MissionCtrl
there were enough changes made to the new capsule prototype that it took the astronaut crew the better part of the week to get back up to speed on systems and procedures to prepare to begin various tests next week
Kerbal Space Agency
@KSA_MissionCtrl
Lead Engineer Simon says the HAB and VAB are ready to get back to work, but Flight Director Lanalye is still waiting for Mission/Launch Control to be brought back online, as it contains the most electronic components. She says mid-next week should see them fully operational again
Kerbal Space Agency
@KSA_MissionCtrl
the fiscal roller coaster ride continues this year, as Head of Finances Mortimer has published bit.ly/FinanceReport_…. We're glad though Genesis was able to afford to continue Dhumla production off-site so it could be ready for testing sooner rather than later
Kerbal Space Agency
@KSA_MissionCtrl
all crew have been recalled this weekend to begin active duty once again starting next week. Everyone else is still working through the weekend and almost around the clock to get KSC back to operational status. Right now that's looking like sometime towards the end of next week
Kerbal Space Agency
@KSA_MissionCtrl
we've taken delivery of the Mk1 Ascension crew capsule, which will be prepared over the next month to be put through a variety of tests starting in January to certify it fit for space flight hopefully later in the year so we can begin sub-orbital kerbed missions
Kerbal Space Agency
@KSA_MissionCtrl
Lead Engineer Simon is happy to be resuming integration in the VAB soon, confirms that we have all the parts ready or on order to arrive in time to complete 2 Mk6-I rockets and 1 Mk6-II rocket for launch in Jan/Feb. 5 Ascension boosters will also be made ready for 2019 launches
Kerbal Space Agency
@KSA_MissionCtrl
no time off this weekend! Everyone is pitching in to begin getting the KSC buildings affected by the EM field back up to operational status by the end of the month, including the VAB and HAB so work can resume on Ascension, Progeny and Genesis projects in December
Kerbal Space Agency
@KSA_MissionCtrl
we just got word from the surface that the EM field has collapsed down to 150m! It will continue to be monitored this week and if it looks to be holding steady we'll begin the work of getting the affected buildings back up to operational status over the next few weeks
Kerbal Space Agency
@KSA_MissionCtrl
we are now just 2 days from projected closure of the bore hole into the crystal base of the Monolith. EM field remains stable - scientists were hoping to see it begin to reduce by now. A large influx of pilgrims has begun to arrive for what they believe will be an event this wknd
Kerbal Space Agency
@KSA_MissionCtrl
the Mk1 crew capsule underwent some more late design changes that builders hoped wouldn't affect the schedule too much but turns out their hopes were a bit too optimistic. Still, delivery is now expected by the end of the month rather than this week so not too bad
Kerbal Space Agency
@KSA_MissionCtrl
bit.ly/KSA_Finances_1… has been posted by Head of Finances Mortimer. We managed a small profit this month thanks to the science missions that were able to be carried out off campus
Kerbal Space Agency
@KSA_MissionCtrl
while we don't need this for our next few Ascension launches, we will still be actively working with the developer to ensure it is a robust and stable tool for more complicated orbital injections in the future. Exciting! 🚀 forum.kerbalspaceprogram.com/index.php?/top…
Kerbal Space Agency
@KSA_MissionCtrl
kerbed space capsule is still on track to be delivered towards the middle of Nov as well and will resume testing ASAP as we would like it to be certified no later than mid-2019. Lots of iffyness but that's the best planning we can do under current circumstances
Kerbal Space Agency
@KSA_MissionCtrl
bore hole measurements made yesterday show it continues to close at a rate that will see it healed up by mid-Nov. We still have to see whether the EM field drops or further reduces its size but if able to resume surface ops, would work towards Jan '19 Ascension & Progeny launches
Kerbal Space Agency
@KSA_MissionCtrl
the effort to penetrate the Monolith has been indefinitely suspended and the bore hole will be allowed to heal. Current estimates put this happening by mid-November. We still don't know if this will bring about the end of the EM field as well, but everyone is hoping it will
Kerbal Space Agency
@KSA_MissionCtrl
Head of Finances Mortimer hasn't had much bookkeeping to do this past month but thanks to KerBalloon we have a small profit to post for September at least docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
the capsule will begin manufacturing to be delivered late November for initial trials to start in December. It will be assembled here in Umbarg and parts come from other caverns, including Kravass, so any future power issues could affect the delivery date
Kerbal Space Agency
@KSA_MissionCtrl
the decision was made late last month during the final stages of capsule testing that neither pod prototype was quite good enough, so engineers spent the last few weeks working furiously on combining the best of both to design the final Mk1 capsule

✨🎊 happy birthday to us!! 🎉✨ Today marks the start of Year 3 for KSA operations. Our founder and Ops Director @DKerman_KSA has some words to share on the current state of things 🥂 kerbalspace.agency/?p=8039
Kerbal Space Agency
@KSA_MissionCtrl
following the Kerbin probes will be named missions into longer-term orbits to carry out various tasks including mapping, communications, science studies and technology testing. Larger Ascension vehicles will be developed to lift heavier loads. No timeline yet for a Munshot, sry!
Kerbal Space Agency
@KSA_MissionCtrl
ultimately, unless failures occur on orbit, none of the Kerbin probes will remain in space and all will eventually decay back into the atmosphere to burn up - except for the RTG test missions of course, which will return the generator to the surface for re-use or safe disposal
Kerbal Space Agency
@KSA_MissionCtrl
what we can say is that the Kerbin series of satellites will test numerous new tech, including reaction control systems, larger-capacity batteries, a radioisotope thermoelectric generator and all the science instruments that will eventually fly on the Extremis probes
Kerbal Space Agency
@KSA_MissionCtrl
not much has been said still of Kerbin I, our first planned satellite to launch when Ascension Mk1 proves it is able to make orbit reliably. It is still under constant redesign as the capabilities of the Ascension Mk1 & satellite requirements on orbit become clearer
Kerbal Space Agency
@KSA_MissionCtrl
although we pulled a net profit for mission expenses, the cost of buying up parts for 5 new Ascension Mk1 rockets, even minus the engines, has once again set us back in the red. August financial report is now available: docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
we've finished transferring what equipment we can from KSC to Umbarg HQ so programs can continue development work as best as possible. Progeny still analyzing Mk6 debris. Extremis plotting trajectories. Ascension reviewing capsule tests. Genesis prepping Dhumla test requirements
Kerbal Space Agency
@KSA_MissionCtrl
great news from across the Kerblantic - bit.ly/DSN_Central has completed construction! It still has a few months of equipment setup & comms cabling to undergo but by early next year we can begin using the 27m dishes for extended downrange tracking of Ascension
Kerbal Space Agency
@KSA_MissionCtrl
TL;DR - we can well-define a "no go" region for future space missions that leaves plenty of room in LKO for kerbed space flight, but there still may be some challenges to advancing further out towards Mun if the radiation discovered at the poles extends far out into space
Kerbal Space Agency
@KSA_MissionCtrl
meet the radiation belt! Or maybe it's just the *inner* belt? Report has been published detailing what our Progeny rocket missions have discovered about the so-called hazardous radiation region up in space: kerbalspace.agency/?p=7937
Kerbal Space Agency
@KSA_MissionCtrl
we now know the EM field is still active because the bore hole is in fact continuing to fill, just at a pace now only measurable in days. New estimates say it could take as long as 3 months to heal. Here is an updated report for the past 2 weeks: kerbalspace.agency/?p=7933
Kerbal Space Agency
@KSA_MissionCtrl
we have released the report on the events that occurred this past Tuesday, which will serve as our Ops Summary for this week. Additional updates will be posted as we get more information on the EM field surrounding KSC. kerbalspace.agency/?p=7917

high-level KSA staff meeting will be held tomorrow to work up a full assessment of the current situation and decide what steps will be taken moving forward over the next several days. We will have details in our Ops Summary
Kerbal Space Agency
@KSA_MissionCtrl
surface team has returned, reports there is a consistent EM field over KSC, tho they found it has a radius of 10km in all directions (assumed out over the water as well) & is not specifically directed @ the space center. Generated current is strong enough to still fry electronics
Kerbal Space Agency
@KSA_MissionCtrl
website and Ops Tracker are now back online as electrical services here in Umbarg become more stable. Still no word from the team dispatched to KSC, but they are not overdue unless they fail to return or get in contact with us by later today
Kerbal Space Agency
@KSA_MissionCtrl
we will release more information on the current situation once we have a better idea what we are dealing with; the past two days have mainly been working to recover basic infrastructure & ensure all our injured employees are being taken care of
Kerbal Space Agency
@KSA_MissionCtrl
hello from KSA HQ in Umbarg! Just calling out to let everyone know we are okay - electrical services are gradually coming back online in all caverns here, but KSC remains off limits until a team sent out yesterday to assess the Monolith's new activity has returned
Kerbal Space Agency
@KSA_MissionCtrl
sorry, we were told it should be STEADLER Engineering Corps. We asked them what it stood for and they said "nothing". Okay.

astronauts are gearing up for a final day of wet capsule testing/training. We'll have more information on what they've been up to these past few weeks in our Ops Summary later today once exercises have concluded
Kerbal Space Agency
@KSA_MissionCtrl
project scientists are monitoring the Monolith for any signs of its old subsonic/EM disturbances as well as the crystal veins locally and off in Kravass & Umbarg for any electrical activity. So far, all signs point to the Monolith remaining inactive
Kerbal Space Agency
@KSA_MissionCtrl
from roughly 30 meters below the Monolith researchers continue to carefully bore up into the crystalline structure they hope leads into the edifice itself. They have nearly reached the bottom and have slowed down to ensure they aren't damaging or triggering anything in the way
Kerbal Space Agency
@KSA_MissionCtrl
Head of Finances Mortimer has posted up our fiscal report for July. Thanks to launch delays and the failed Progenitor mission, this month went far deeper into the red than we planned. Here's hoping we can bounce back a bit in August docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
which, paradoxically, aren't actually that hard. Especially since we are just doing flybys without orbital insertions or landings. Getting the probe safely into an optimal ejection orbit ready to go? Half the journey
Kerbal Space Agency
@KSA_MissionCtrl
weather remains unsuitable for flight so Deuce mission will have to try again on Monday. It was a slow week, but you can still check out our weekly Ops Summary in case you missed anything: kerbalspace.agency/?p=7811
Kerbal Space Agency
@KSA_MissionCtrl
astronauts just finished their second night time wet capsule exercise today, working to ensure that we can return and recover a vessel under as many conditions as possible, since landing where we want to land might not always be an option
Kerbal Space Agency
@KSA_MissionCtrl
Progeny Mk6 launches are so routine nowadays but Ascension Mk1? Not even close! Here's the meaty flight analysis read you've been waiting for. Third time is very much looking to be the charm: kerbalspace.agency/?p=7786
Kerbal Space Agency
@KSA_MissionCtrl
KSC has weathered the storms and we'll be moving operations back to the campus today. We will have updates throughout the day on new dates for the various missions that were put on hold as staff get re-situated and back on track
Kerbal Space Agency
@KSA_MissionCtrl
latest report from the surface is the high pressure system has collapsed and strong storms are now sweeping through the region. KSC is buttoned up and shouldn't have any issues with the weather although flooding is a minor concern
Kerbal Space Agency
@KSA_MissionCtrl
astronauts also remain stood down from capsule testing - though there was the idea to move north to Kravass, which is seeing normal weather patterns, logistically by the time all was said and done, conditions likely would have returned to normal here at KSC anyways
Kerbal Space Agency
@KSA_MissionCtrl
science team was back up on the surface earlier at mid-day to gather temperature data & took a photo as they headed back to Umbarg - rarely do we see perfectly clear skies at KSC. You can almost feel the heat coming off the photo. It was baking up there, reaching 102°F!
Kerbal Space Agency
@KSA_MissionCtrl
because of the hold on production, we won't have another engine delivered until the beginning of Sept at the earliest, but after that they will start arriving more frequently and allow us to condense our launch schedule for Ascension rockets
Kerbal Space Agency
@KSA_MissionCtrl
Ascension team is still going through their post-flight analysis but enough data has been reviewed to clear the K2-X engine of any issues & confirm metal fatigue was to blame for the first launch engine failure. NovaPunch will now resume production of the engine
Kerbal Space Agency
@KSA_MissionCtrl
the last episode, back in 2016, lasted several days. Hopefully this one is shorter. Either way, both Progeny launches are now suspended and will be assigned new launch dates once we can comfortably resume surface activity twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
this has happened before & after much investigation scientists still don't fully understand what's going on but say a mixture of ocean currents, jet stream bending and moisture levels in the air can apparently combine under the right conditions to form a very localized heat wave
Kerbal Space Agency
@KSA_MissionCtrl
we are suspending all surface operations and pulling back all staff to Umbarg HQ due to temperatures increasing near 100°F as a high-pressure system sits over our region. We just can't keep our facilities cool enough in this heat for a proper work environment
Kerbal Space Agency
@KSA_MissionCtrl
initial testing earlier today after 2nd sunrise has shown the concept of hooking a capsule via airship for extraction at sea (and no doubt easier on land) is a feasible idea that still has a lot of problems to be worked out
Kerbal Space Agency
@KSA_MissionCtrl
an airship has been tethered to the KSC Village warehouse berth this week, where it has been fitted with a hook and winch mechanism so tomorrow they can test picking up the capsule prototypes out of the water
Kerbal Space Agency
@KSA_MissionCtrl
decision was made to recall the airship rather then expend further funds searching an ever-increasing area. Our primary goal being reaching orbit and with no inflight mechanical anomalies, recovering the rocket is not a priority. Ascent data we have is good enough to work with
Kerbal Space Agency
@KSA_MissionCtrl
earlier today the recovery airship flew in contact range of Ockr to report that they have failed to find any locator beacon signal nor sign of impact area on the landscape. They dropped a sonar buoy in the waters of the search area and heard no pings
Kerbal Space Agency
@KSA_MissionCtrl
astronauts are ending the day cycle soaking wet after various attempts at being recovered from both capsule prototypes out at sea. A larger float collar for the taller one has worked well, but the extra weight and packaged size isn't pleasing engineers
Kerbal Space Agency
@KSA_MissionCtrl
although we're hoping to hear from the recovery airship today, chances are that since it hasn't reported back yet then it's on a hunt for a crash site somewhere in the yellow area. We can only make a best guess of rocket heading at re-entry based on data we have prior to LOS
Kerbal Space Agency
@KSA_MissionCtrl
KerBalloon mission to the Badlands has returned after a successful trip. It was night for them during the Ascension launch but unfortunately it was too low over the northern horizon for them to see it re-enter
Kerbal Space Agency
@KSA_MissionCtrl
telemetry data from yesterday's flight up to the point where signal was lost has been posted. Mission analysis has already begun, taking a close look at why the rocket failed to pitch over as much as it should have in early ascent phase docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
no word still from the airship, but it has several hundred km to search along since we don't know how fast the rocket will fall when it's using its control surfaces to glide down. If it fails to pick up a signal it will backtrack slower & lower to look for a crash site
Kerbal Space Agency
@KSA_MissionCtrl
post-launch activities winding down, 2nd Wx balloon recovered offshore. Progeny launch base will be returned to the pad today. The earliest we would expect to hear from the airship would be late tonight, as it still has not even gotten halfway to the search area as of right now
Kerbal Space Agency
@KSA_MissionCtrl
we had airships staged at Ockr & Kravass to head east or west as needed, and the one at Ockr already departed once we knew rocket was sub-orbital. It'll search along the last known trajectory for the landing site, listening for the radio locator beacon, which has 2 days of power
Kerbal Space Agency
@KSA_MissionCtrl
we got one last photo from 200km (it was every x50 on the way up and x00 on the way down) before Ockr lost signal, looking south along the terminator over the night side of Kerbin. Fabulous! Now let's just hope we can recover all the rest of the data

loss of signal from KSC, but both Ockr and Sheltered Rock still have line of sight and data relay is up and running great. Trajectory analysis however shows Ockr will lose signal well before the rocket begins to re-enter the atmosphere in ~5 minutes
Kerbal Space Agency
@KSA_MissionCtrl
the view from apokee, 268km and rocket has drifted around looking along its direction of travel towards the terminator. We are high enough the glare from the planet is reduced enough the camera can resolve some stars and nebulae filaments
Kerbal Space Agency
@KSA_MissionCtrl
250km up a short while ago, still looking towards Sheltered Rock but Ockr is also now in the frame, hidden below cloud cover in the bottom right. Rocket was 572km downrange at the time of the photo, is currently 726km downrange and approaching apokee
Kerbal Space Agency
@KSA_MissionCtrl
here's a shot from 150km, looking down at Sheltered Rock. We may not have Kerbin in the frame for all these photos - rocket is on a slow spin and tumble so wherever the camera ends up pointing is what we get. Also takes 1-2min to downlink photo so rocket is already past 150km
Kerbal Space Agency
@KSA_MissionCtrl
behold our first photo from space! Booster cam is capturing video but we don't have enough power to spare to beam that back so it will send us still images instead at preset points along the trajectory. First one is from 80km, looking back down towards KSC
Kerbal Space Agency
@KSA_MissionCtrl
flameout! Tanks have run dry and left us on a sub-orbital trajectory, but we did come very close to perikee positive (it starts at nearly -600km). Rocket now coasting up to a 268km apokee over the next 8 minutes
Kerbal Space Agency
@KSA_MissionCtrl
46° at 20km was better but the slower-than-planned pitch-over in the beginning may have cost us an orbit. Perikee is dropping fast now as rocket pushes through the outer atmo, pitched at 14°. Only a few seconds of fuel remaining. Engine chamber pressure remains nominal
Kerbal Space Agency
@KSA_MissionCtrl
rocket is through max dynamic pressure and throttle hold is engaged to ensure the rocket does not go too fast through the atmosphere. 66° pitch at 10km is bit behind target - now passing through 15km we want it to reach 45° by 20km. It also just passed Mach 2
Kerbal Space Agency
@KSA_MissionCtrl
good ignition, throttle up and clamp release for LIFT OFF of the 2nd Ascension Mk1 Block I making another attempt at orbit! Tower is cleared and the rocket has begun to turn towards the horizon, aiming to be at 60° pitch by 10km
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] rocket is on internal power and service tower booms have moved aside. RF comms check is good, battery drain rate is nominal. These are the final steps the rocket will take before lift off. Follow its ascent on our Ops Tracker! bit.ly/AscensionMk1B1…
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] Terminal countdown begins! AFCS now takes full control of the rocket from this point forward, ensuring all systems remain nominal during engine ignition and run-up prior to commanding release of the support collar to begin ascent
Kerbal Space Agency
@KSA_MissionCtrl
[L-3m] preliminary tank pressurization underway to add structural rigidity to allow the rocket to stand on its own atop its engine support collar once the service tower booms swing away prior to ignition
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] Final readiness polls complete: Wx: GO; Range: GO; Flight: GO; Tracking Station: GO; Downrange Tracking: GO; Ops Director: Launch permission granted! 🚀 GO ASCENSION 🚀 FTS on internal power, service tower booms unlocked to prep retraction, AFCS awaits terminal count
Kerbal Space Agency
@KSA_MissionCtrl
[L-13m] nitrogen gas now being pumped into pressure containers onboard the rocket and will be used to maintain tank pressure during flight to feed the engine. This is done late to ensure any tank rupture does not harm pad workers
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] we have broken skies to the south and Umbarg confirms clearer weather is heading our way! Countdown has been restarted. RSO confirms pad is clear, Hoodall confirms range is clear - rocket is now ARMED for ignition, Flight Termination System is ACTIVE
Kerbal Space Agency
@KSA_MissionCtrl
Wx update: sky remains overcast, clouds low at ~2.5km. Winds still light out of the SW. Hold remains, rocket still healthy. Controllers using the time to run extra system checks and launch drills
Kerbal Space Agency
@KSA_MissionCtrl
upper-level wind conditions are nominal. Balloon will pop soon & splashdown just off the coast, where a recovery boat from MSV Hoodall will collect it and return it to shore so its meteorological instrument can be mounted to the second balloon if needed
Kerbal Space Agency
@KSA_MissionCtrl
[HOLD] we will standby at L-15min, prior to range closure and tank pre-pressurization, until we have indication of clearer skies coming our way. Umbarg is to the SW and will be able to give us notice of better conditions. Wx updates will be posted every 30min
Kerbal Space Agency
@KSA_MissionCtrl
sunrise shows we have broken skies off in the distance to the east but unfortunately off to the right out of picture to the south no clear skies are in sight at the moment
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] winds continue to remain light out of the southwest, no showers or thunderstorms in the area. Clouds remain overcast and low but we still have time for skies to clear so weather is GO to continue into final countdown!
Kerbal Space Agency
@KSA_MissionCtrl
[L-45m] inside an hour to launch and all continues to progress well - pad is secure and clear of personnel. A fuel truck left behind hooked up to the service tower contains the pressurization gas to onload later in the countdown. Launch rehearsal has begun
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h20m] balloon crews have driven UTVs southwest of KSC beyond the hills to the grasslands near the shores to release the high-altitude balloon for checking upper-level winds. Three are prepared but all are sharing parts so only one is ready to go at a time
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h30m] wrapping up preflight with a clear issues board - a few minor problems cropped up yesterday leading up to the hold-down fire test and were resolved. MSV Hoodall is on station and working with the Range Safety Officer to secure the ascent corridor
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h55m] no issues being worked, rocket is now ready for controllers to check over its engine and ignition systems. Pad is clearing of personnel out to 500m, with a quick response team sheltering in the nearby bunker
Kerbal Space Agency
@KSA_MissionCtrl
all viewing areas are open - please remember that hearing protection is REQUIRED! KSC staff will be checking all kerbs and moving any without protection indoors. If you're seen removing protection during the launch you will be banned from future visits
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h40m] after a trip to the VAB to refill and back to the pad for each tanker, 7 tons of liquid fuel and oxidizer have now been onloaded to the rocket. System checks and pad close outs will now continue as fuel levels are monitored for any leaks
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h15m] Automated Flight Control System initialized, rocket and pad are configured for fueling operations to begin, FD Lanalye has given the GO for tankers to hook up and begin pumping propellants onboard. AFCS code changes can be viewed at bit.ly/AFCS_ChangeLog
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h30m] we are GO to enter pre-flight ops! Weather reports show no rain or storms in the area, chance of development throughout today is low. Winds are light, leaving mostly cloudy skies to be our main source of weather issues leading up to launch time
Kerbal Space Agency
@KSA_MissionCtrl
the one noteable change between this flight and the first launch is the rocket won't increase pitch-over once it's past MaxQ - it will be aggressively pitching over from the moment it clears the tower, moreso than the first launch
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h] Launch Control begins to fill up with staff as Flight Director Lanalye prepares to brief the team one last time on today's flight, which they've been rehearsing the past 2 weeks. Here's what the rocket will aim to accomplish on this mission
Kerbal Space Agency
@KSA_MissionCtrl
launch day! Weather reports have begun to be collected by our meteorological team from around the region via airships, weather station and maritime vessels. The rest of today's launch timeline will also be the same as last launch. Expect updates at these milestones

@KSA_MissionCtrl
Ascension Mk1 was successfully raised vertical and hooked up to its engine support collar and service tower umbilicals. Flight Director Lanalye and her team are now prepping the rocket for a hold-down fire to check the engine's flight readiness
Kerbal Space Agency
@KSA_MissionCtrl
Sheltered Rock and Ockr have completed comms testing and Tracking Station reports all is ready to keep tabs on the Ascension Mk1 as it makes a second attempt for orbit tomorrow, passing northeast over both caverns on its way... into the history books?

@KSA_MissionCtrl
3rd sunrise approaches and weather remains poor for both flight crew and astronaut crew. Don't think they're sitting around twiddling their toes though, everyone still has plenty of indoor work to keep them busy. Still continuing to hope for better weather later today
Kerbal Space Agency
@KSA_MissionCtrl
Ascension Mk1 Block I rocket is loaded up on its carry vehicle ready for rollout early on Monday and later in the day will undergo a hold-down firing test of its engine prior to being cleared for launch on Tuesday
Kerbal Space Agency
@KSA_MissionCtrl
rocket carry/release standing down until next day cycle. Weather has also so far prevented the astronaut crew from performing wet capsule exercises thanks to excessive waves heights, even in the bay, due to winds
Kerbal Space Agency
@KSA_MissionCtrl
Ascension Mk1 was laid horizontal today after no issues were found with load bearing after vertical stacking yesterday. It will undergo final checkouts today and tomorrow before being loaded up on the carry vehicle for its trip out to the pad on Monday
Kerbal Space Agency
@KSA_MissionCtrl
you didn't forget there was a rocket launching next week did you? Two, in fact! An Ascension Mk1 Block I is being topped off today while a Progeny Mk6 Block I works to complete assembly next week. See the bit.ly/Ops_Tracker for launch date details!
Kerbal Space Agency
@KSA_MissionCtrl
astronaut crew spent today getting ready to begin wet capsule testing over the next week - starting in the calmer bay waters north of KSC. These operations will be planned & executed carefully as the risk of drowning is ever present
Kerbal Space Agency
@KSA_MissionCtrl
astronauts spent a good deal of time today clambering into and out of both pods under various conditions - some cases were flagged as potentially life-threatening, twice two of them "died". This is why we test & train hard!
Kerbal Space Agency
@KSA_MissionCtrl
all the parts are here for the second Ascension Mk1 Block I vehicle to finish assembly on schedule next week. VAB is also sending the Progeny MK1-B back over to the HAB to be mounted atop the Deuce, itself finishing repairs just yesterday
Kerbal Space Agency
@KSA_MissionCtrl
issues with the trajectory analysis tool that were causing problems giving us future SOI encounters for Alaba have been confirmed fixed. We will definitely continue to help make KSPTOT a more robust tool for everyone! forum.kerbalspaceprogram.com/index.php?/top…

@KSA_MissionCtrl
another successful splashdown, although the taller capsule had trouble staying upright and will need a larger flotation collar. Crews are hauling it back onbard MSV Tongjess to sail home
Kerbal Space Agency
@KSA_MissionCtrl
successful splashdown of the first capsule, second capsule is already halfway through its ascent. First capsule will be towed back to the MSV by the tender then winched up to the deck via the wet ramp in the rear
Kerbal Space Agency
@KSA_MissionCtrl
first capsule has begun its ascent up to 16.5km, the thin ring of float collar can be seen underneath. It will reside beneath the heat shield, which would have been dropped after chute deployment to clear the float for touchdown
Kerbal Space Agency
@KSA_MissionCtrl
MSV Tongjess has the capsules and crew aboard and has departed to sail about 20 kilometers offshore to release and recover the first capsule. Like the previous land-based exercise, capsules will remain unkerbed
Kerbal Space Agency
@KSA_MissionCtrl
although sunrise is still a ways off, much like this old photo an MSV is parked offshore and crews will be ferrying equipment and the capsules over for water recovery checkouts a few kilometers out into the Kerblantic next day cycle
Kerbal Space Agency
@KSA_MissionCtrl
we can get into a low orbit on a single burn but for higher altitude/heavier payloads we'll need a vacuum engine to take up the charge in space. Bluedog Design Bureau has won the contract, presenting us with a great second-stage pusher
Kerbal Space Agency
@KSA_MissionCtrl
both capsules will be given a thorough check-out in the VAB to ensure that they were not damaged by yesterday's test. Chutes will be repacked and flotation collars are ready to be installed through tomorrow for water recovery exercises later this week
Kerbal Space Agency
@KSA_MissionCtrl
crews were better positioned for recovery of the 2nd capsule, the triple chute makes it easier to spot from further away and provides some redundancy - if one fails that will be a rough but still survivable landing
Kerbal Space Agency
@KSA_MissionCtrl
same routine, different capsule - crews are heading back out west for another drop and recovery. Astronauts are involved with both exercises even if none of them are actually inside the capsules as they return (yet)
Kerbal Space Agency
@KSA_MissionCtrl
report from recovery crew is the capsule landed just fine, if a bit buried in the mud. They are digging it out and packing everything up to head back to KSC so they can finish preparing the second capsule for its test later today
Kerbal Space Agency
@KSA_MissionCtrl
we had a good ascent, capsule was released at max altitude and fell to 1.5km AGL before chutes were popped. Telemetry reports a descent rate that matches full deployment of the canopies. Crews are still trying to reach the landing site - ground remains soggy
Kerbal Space Agency
@KSA_MissionCtrl
capsule has begun its journey up to 16.5km, Tracking Station will soon pickup its signal and monitor the internal pressure as it rises at ~5m/s. Crews are piling back into vehicles to track and be nearby for recovery when it lands
Kerbal Space Agency
@KSA_MissionCtrl
the convoy has departed KSC, making for the Grasslands just a few km to the west - carry vehicle isn't really an off-roader so they can't go far but want to ensure wherever balloon drifts after release it stays over land for recovery
Kerbal Space Agency
@KSA_MissionCtrl
weather looking much more favorable today, crews loading the first capsule onto the carry vehicle to head out with sunrise. Capsule will be unkerbed but onboard pressure systems will be running and a dummy weight will be inside
Kerbal Space Agency
@KSA_MissionCtrl
adverse weather has kept Ascension crews from performing capsule drop tests today as planned. It's not the rain itself but the fact that vehicles will be more likely to get stuck in mud out in the Grasslands where the exercise will take place
Kerbal Space Agency
@KSA_MissionCtrl
in related news however scientists have released a new post detailing the findings of the recent Progeny flights in regards to the hazardous radiation region, now closer to being called a "belt" - kerbalspace.agency/?p=7542

Ascension engine support collar has been removed and the Progeny launch base has been returned to the launch pad, strengthened to handle the extra weight and length of the Mk6 Block II. Launching direct east, service towers pose no hazard. Hopefully weather improves for launch
Kerbal Space Agency
@KSA_MissionCtrl
VAB is so busy right now the two capsule prototypes that arrived today have just been parked outside until the Progeny Mk6-II rolls out tomorrow. The astronauts and other Ascension team members can't wait to get hands-on with them to begin assessing the designs

Kerbal Space Agency
@KSA_MissionCtrl
telemetry data from last flight has been updated, but not fully as there was a crash at chute deploy, which did fail. Onboard accelerometer though froze with last reading on impact and rocket hit the water traveling just over 300m/s docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
inspection of the pad and ground service equipment has been completed without issue. A good deal of refurbishment will still be needed to get everything ready to launch again next month, but this was expected & crews will get to work on that tomorrow
Kerbal Space Agency
@KSA_MissionCtrl
the nose of the test weight is almost completely crushed, so looked at first glance earlier like chute deployment failed and the rocket dove straight into the water. But we'll find out for sure because data onboard is intact! Test weight was purposely built to insane tolerances
Kerbal Space Agency
@KSA_MissionCtrl
the engine looks as we would expect if the bell failed during flight but we also don't know yet for sure exactly how the rocket landed so too soon still to say whether all the damage seen is just from during flight
Kerbal Space Agency
@KSA_MissionCtrl
test weight and engine have come ashore and will be moved into the HAB for analysis since the VAB is rather packed right now. Everyone is eager to see if the data stored in the test weight is still intact
Kerbal Space Agency
@KSA_MissionCtrl
we've called off the search for any large remains of the fuel tank and are certainly satisfied with the engine and test weight. They'll be in the hands of Lead Engineer Simon and the Progenitor teams early tomorrow so they can begin analysis
Kerbal Space Agency
@KSA_MissionCtrl
the second of 4 potential sites for the Ascension Mk1 engine turned out to be the real deal. More searching is being done for the fuel tank but salvage crews say both the test weight and engine show significant damage unrelated to impact with the water
Kerbal Space Agency
@KSA_MissionCtrl
report from the salvage ship is they think scans of the bottom have found the engine, but no sign so far of the fuel tank - at least nothing big enough to guess is the fuel tank. If it did explode, not much would be left to pick out among the surface scatter
Kerbal Space Agency
@KSA_MissionCtrl
several days since launch now and still no outwards signs of activity from the Monolith, according to researchers. New plans are still being drawn up to attempt to get access to the inside
Kerbal Space Agency
@KSA_MissionCtrl
salvage ship raising the Ascension Mk1 rocket says they have only brought the test weight to the surface. They are searching the sea bed starting in a 5km area to see if the rest of the rocket can be found. Test weight was the only part with a locator signal
Kerbal Space Agency
@KSA_MissionCtrl
salvage ship has contacted us through Sheltered Rock that they have arrived over the splashdown site, still have a strong ping from the rocket and will begin operations to raise it tomorrow

astronauts are glad for a weekend break, say their heads are about to explode cramming all the information just from the two capsule manuals, which they are still working through ahead of their delivery later this month
Kerbal Space Agency
@KSA_MissionCtrl
what a week! Lots to do now before we're ready to send up the second Mk1 next month, learn about that and more on what else transpired at KSC via bit.ly/OpSummary6-4-18
Kerbal Space Agency
@KSA_MissionCtrl
we're a bit concerned that it's on the sea floor as the fuel tanks should have kept it afloat after splashdown. They could have been damaged and ruptured however since they were still pressurized and if impact was too fast... we'll find out next week
Kerbal Space Agency
@KSA_MissionCtrl
the rocket survived!! Lymun picked up its locator ping and was able to reach Sheltered Rock with the news. It is submerged in ~400m of water and we will have a salvage ship onsite early next week to haul it up and bring it back. Whoop whoop! \[0o]/
Kerbal Space Agency
@KSA_MissionCtrl
despite the engine failure, achieving orbit wasn't the only goal of this mission. The new flight guidance software worked as expected, the ground support equipment functioned as planned, overall we are pleased with the rocket's performance up to engine failure
Kerbal Space Agency
@KSA_MissionCtrl
we figure Lymun is still ~1.5hr away from the estimated landing area, and even then we don't know if they will be able to reach us or Sheltered Rock via skip comms to pass on any information. Might be a late day waiting...
Kerbal Space Agency
@KSA_MissionCtrl
post-launch ops are ongoing, everyone outside was in awe of the launch, said they could feel the sound of the rocket engine in their bones as it headed skyward. Science and education committee chair says she was impressed yet again by what we are doing here
Kerbal Space Agency
@KSA_MissionCtrl
rocket should have returned by now, over land or water? Hard to tell - it's right near the coast. MSV Lymun is in the process of retrieving the KerBalloon launched earlier & will then head for the landing zone to see if it can pick up a locator beacon (land) or sonar ping (water)
Kerbal Space Agency
@KSA_MissionCtrl
ok, we got a "status dump" that shows the code did hang up somewhere but not completely, is prepping for re-entry & chute deploy. We expect loss of signal soon, don't expect to pick it up again before landing - rocket is falling into a comms dead zone between us & Sheltered Rock
Kerbal Space Agency
@KSA_MissionCtrl
passed through apokee of 101.82km, strangely we're not getting expected status updates from the AFCS but the telemetry data it collects is still being transmitted so the computer hasn't frozen... hopefully the return code will trigger for chute deployment...
Kerbal Space Agency
@KSA_MissionCtrl
reports of absurdly low chamber pressure and fuel drainage spiked @ L+1m32s - it looks like the engine bell has failed. Rocket will coast through space a little bit before returning, sadly will not be orbiting Kerbin. Sheltered Rock reports AOS
Kerbal Space Agency
@KSA_MissionCtrl
rocket is actively steering itself downrange, pitching gradually through Max Q before really starting to work towards flying more horizontally, throttling back as it climbs to maintain constant acceleration. All systems remain nominal, now passing thru 16km @ 664m/s
Kerbal Space Agency
@KSA_MissionCtrl
we have LIFT OFF!! Initial ascent is slow after launch as full thrust is not needed & would just add wear to the pad, engine clamp, and possibly the service towers. Once the rocket is clear of the towers the engines throttle up to full thrust for a TWR of 1.7
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] prepping for ignition again. The hold-down sequence prior to lift off could one day be removed but for these initial flights, as demonstrated, it serves as a good checkpoint for new hardware and systems. Crossing fingers now...
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] second launch attempt is underway as the countdown restarts from 2min and the AFCS once again takes control of the launch sequence. If everything else remains the same as last time, we should be good to go!
Kerbal Space Agency
@KSA_MissionCtrl
although it's been a while since the originally planned launch time, upper-level wind data remains valid. If this launch attempt fails though we will have to release a second balloon and wait an hour for it to ascend into the upper atmosphere for new data
Kerbal Space Agency
@KSA_MissionCtrl
Lead Engineer Simon has conferred with Ascension engineers and all agree we can widen our constraints. FD Lanalye has reset the count to T-2min but cloudy skies have returned. Broken clouds are approaching though & L-0 is set for 21:07 UTC
Kerbal Space Agency
@KSA_MissionCtrl
full check of all systems has not turned up any issues that may have been missed during preflight ops, so conclusion is the inputted constraints on chamber pressure did not take into account this engine has undergone multiple static fires and is not brand new
Kerbal Space Agency
@KSA_MissionCtrl
abort thrown was related to engine chamber pressure, which was slightly lower than what the AFCS was programmed to expect. Controllers will now work to determine why. Tank pressure? Pumps? Mixture? Meanwhile, rocket can and will remain primed for launch. Standby!
Kerbal Space Agency
@KSA_MissionCtrl
AFCS threw an abort after engine ignition at approx T-3s. Engine was automatically shut down and controllers are reviewing abort data to determine if we can attempt another launch. Engine can be ignited as often as needed as long as it's hooked up to pad equipment
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] assuming all is Go on final primary station readiness poll at T-30s here is what will happen in the final moments leading up to launch. Don't forget the Ops Tracker has real-time ascent updates: ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] terminal count sequence has begun as the AFCS takes over to perform the sequence of events that will lead to launch. Service towers have retracted. Rocket is now on internal power, RF comm check underway
Kerbal Space Agency
@KSA_MissionCtrl
[L-3m] preliminary tank pressurization underway to add rigidity so the rocket can stand on its own, mainly against lateral movement from winds (not a high concern today) atop the engine support collar until launch once the service tower booms have detached and swung away
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] Final readiness polls complete: Wx: GO; Range: GO; Flight: GO; Tracking: GO; Ops Director: Launch permission granted! 🚀 GO ASCENSION 🚀 FTS transitioning to internal power, service tower boom locks disabled to prepare for retraction
Kerbal Space Agency
@KSA_MissionCtrl
[HOLD] final readiness poll was not passed, both weather and range agreed cloud conditions are no conducive to good viewing for initial ascent. Good news is that clearer skies are on the way and we've only pushed L-0 back by 5 minutes, now 20:29 UTC
Kerbal Space Agency
@KSA_MissionCtrl
[L-13m] new procedure in our launch timeline has nitrogen gas onloaded for tank pressurization. This gas is itself stored under high pressure when onboard the rocket on the pad and is an explosive risk when crews are in the area

[L-15m] RSO has confirmed the launch pad is cleared of all ground crew, Lymun reports waters and airspace northeast of the pad are clear - rocket ignition system is ARMED and flight termination system is ACTIVE. Anything seen w/in 500m will hold count
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] still a few minutes from sunrise but general weather conditions are deemed good enough to proceed into the final countdown. Cloud cover is still looking low and thick, so that will likely be our main concern this day cycle. No issues being worked
Kerbal Space Agency
@KSA_MissionCtrl
[L-45m] launch rehearsal gearing up to get underway and ensure that all systems, pad and range assets are properly configured and controllers know their roles
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h20m] KB crew has released a weather balloon to ascend up and assess upper-level winds by launch time. Surface winds out of the SSW tailing the rocket give us a large margin but are currently nowhere near violation levels
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h30m] pre-flight operations are wrapping up, issues board remains clear. MSV Lymun will be providing range services for us today, has reported on station to work with Range Safety Officer to ensure our launch corridor is secure. Final pad closeouts underway
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h55m] fuel system is showing no leaks, all pad workers except the bunkered quick response team are clearing out to 500m so launch controllers can run checks of the engine and ignition systems. This engine does not gimbal - one less thing to worry about
Kerbal Space Agency
@KSA_MissionCtrl
viewing areas have been modified to provide faster access to shelter even tho still outside of blast area. In addition, *anyone* outside MUST wear hearing protection. We have rentals at the Support Village if you did not bring your own. NO EXCEPTIONS
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h40m] fueling was completed without issue, tanks are topped off with 3.150t of liquid fuel and 3.850t of oxidizer. Rocket now masses a total of 10.427t. Payload is 1t. Want more info? Check it out on our Ops Tracker: ops.kerbalspace.agency
Kerbal Space Agency
@KSA_MissionCtrl
yes we can, but it hasn't yet become anywhere near impractical using these to justify the cost of purchasing new ones. If it took like 8 trips and half a day cycle to fill a rocket then that would be a bit absurd...
Kerbal Space Agency
@KSA_MissionCtrl
halfway done with fueling, trucks have to return to the VAB to top off their tanks and make a second trip out to the pad to get the rocket to flight levels
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h15m] rocket is in good condition and configured for fueling. Trucks are out at the pad getting hooked up, service structure is also configured for fueling - manual valves are set by the pad crew to allow fuel to flow through the towers - 7t worth
Kerbal Space Agency
@KSA_MissionCtrl
software engineers have shuffled around some core AFCS components and streamlined the overall operations sequence. Lessons learned from the last Progeny flight have also been implemented, like radar altitude measurements for chute deployment
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h30m] controllers are all on console ready to begin preflight procedures, starting with waking up the rocket and ensuring everything is still nominal from its rest on the pad, then loading operations code: bit.ly/AFCS_ChangeLog
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h] Flight Director Lanalye is assembling her team for final pre-launch brief. Here's an overview of what is planned for today's mission. If anyone has any questions, just ask!
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h30m] the launch timeline is mostly similar to Progeny launches with a few additions and 20 minutes extra time for tanking. Starting to gather weather reports from maritime and airship sources in the region. Expect further updates at these milestones
Kerbal Space Agency
@KSA_MissionCtrl
hopefully we get to launch a rocket today! Hopefully that rocket makes it into orbit! Kerbs across campus are well-rested and all in the process of gearing up and getting organized to begin pre-launch operations @ 15:54 UTC

@KSA_MissionCtrl
it's a late call but WDR was solid and everyone is in favor of launching tomorrow. Ops Director @dkerman_ksa can't see any reason for further postponement and has signed off on the readiness reports. We are 🚀 GO FOR LAUNCH! 🚀 L-0 set for 20:24 UTC
Kerbal Space Agency
@KSA_MissionCtrl
the "launch" was good and propellant is now being offloaded for crews to approach the pad for a final check of all ground systems. Lanalye is working with Lead Engineer Simon to assess rehearsal performance & submit a final readiness report for review
Kerbal Space Agency
@KSA_MissionCtrl
nearing simulated launch time and surprisingly things are going very well. Flight Director Lanalye says all systems are operating nominally. Although no launch is planned, the area around the pad out to 500m is still clear of personnel
Kerbal Space Agency
@KSA_MissionCtrl
tanks are at flight levels! Countdown procedures continuing all the way to L-0 (no hold-down engine firing) and then a launch simulation will run the flight software through its paces. Still lots of problems to discover, no doubt
Kerbal Space Agency
@KSA_MissionCtrl
teams feel they have resolved all issues with our ground support equipment and are prepping for another tanking of the rocket, hoping to top off and continue with the wet dress rehearsal countdown timeline
Kerbal Space Agency
@KSA_MissionCtrl
VAB has begun to work on finishing the assembly of the Progeny Mk1-B that will be carried atop the Deuce while integration work continues on the two Mk6 Block II vehicles and parts are starting to arrive for the second Ascension Mk1 launching next month
Kerbal Space Agency
@KSA_MissionCtrl
while service tower issues are being worked, launch readiness is still ongoing at the Tracking Station, working once again with comm substations in Sheltered Rock and Ockr to ensure we can follow the flight all the way to orbit
Kerbal Space Agency
@KSA_MissionCtrl
it's worth pointing out that both the Progeny Mk6 and the Ascension Mk1, in terms of power, are capable of achieving orbit. The only thing that allows the Ascension Mk1 to actually do it (relatively easier) is the fact that it can steer itself
Kerbal Space Agency
@KSA_MissionCtrl
taken earlier at sunset a replica of the Progeny Mk4, first rocket to space, and off in the distance stands the Ascension Mk1, first rocket capable of orbital flight. Hopefully it can achieve it tomorrow. Crews are back to work resolving service structure issues
Kerbal Space Agency
@KSA_MissionCtrl
Monolith researchers have been continuing to monitor the edifice closely as we approach full launch readiness. There is still no outwards signs of activity but concern remains (mostly among the public) that bringing a bigger rocket out to the launch pad could have some effect
Kerbal Space Agency
@KSA_MissionCtrl
today's second attempt at fueling progressed further, but we're still experiencing multiple issues that need to be resolved, mainly regarding the service towers. Launch attempt has been pushed further back to NET than 6/8 @ 14:23 UTC
Kerbal Space Agency
@KSA_MissionCtrl
did you know it costs less to build (not buy) and deliver to the launch pad an Ascension Mk1 rocket as opposed to a Progeny Mk6? The Ascension may be bigger but it is also relatively less complex. The size increase is mainly due to needing more fuel
Kerbal Space Agency
@KSA_MissionCtrl
Assembly member who chairs the committee for science and education will be making her second visit to KSC to witness the upcoming launch, she was last here back in Oct '16 to see a Progeny Mk1-B take flight. We appreciate the government's continued interest in our activities
Kerbal Space Agency
@KSA_MissionCtrl
several minor issues cropped up during fueling of the Mk1, rocket is being drained back and crews will endeavor to resolve the problems for another attempt later today
Kerbal Space Agency
@KSA_MissionCtrl
sunrise approaching, prepwork underway for the Ascension Mk1 wet dress rehearsal after a dry one yesterday. Today we will actually be loading propellant onboard through the service towers. Fuel trucks hook up at the base
Kerbal Space Agency
@KSA_MissionCtrl
Flight Director Lanalye and Lead Engineer Simon are both satisfied with testing today and have cleared the Ascension Mk1 through to its wet dress rehearsal tomorrow. One step closer to launch!
Kerbal Space Agency
@KSA_MissionCtrl
today Ascension teams will be working to ensure all launch systems are ready, both in the control center and out on the pad. The rocket is already pointed 45°N, the NRAP logo marks the "top" if it were laid horizontal, and defines which of the 4 ctrl surfaces roll/pitch/yaw
Kerbal Space Agency
@KSA_MissionCtrl
the rocket will remain out on the pad until launch, tomorrow the teams will run through checks of the ground support equipment (service towers & engine collar). If all looks good a wet dress rehearsal will take place on Wednesday. Launch is now NET than 6/7 @ 14:20 UTC
Kerbal Space Agency
@KSA_MissionCtrl
pad workers have successfully placed the rocket into its engine support collar and hooked up the service tower arms. Here is a look at the lift from earlier - the collar raises to attach to the engine base
Kerbal Space Agency
@KSA_MissionCtrl
3rd sunrise is here, winds are still out of the east but have died down enough that crews feel safe erecting the rocket, now making its way back to the pad aboard the carry vehicle at 1.5m/s, just a bit faster than the average walking pace
Kerbal Space Agency
@KSA_MissionCtrl
high winds off the water with stronger gusts have prevented the Ascension Mk1 rollout this day cycle. No one wants to see it make a successful lift to vertical only to be blown over (main concern is the wide lift platform, not the rocket itself)
Kerbal Space Agency
@KSA_MissionCtrl
carry vehicle has been repaired and tested in the VAB, Lead Engineer Simon reports it will be ready to attempt another roll out tomorrow
Kerbal Space Agency
@KSA_MissionCtrl
let's wrap up this week with bit.ly/OpSummary5-28-… - learn more about our new recruits and why female flight instructor Helta turned down our request to join the Agency
Kerbal Space Agency
@KSA_MissionCtrl
good news however is everyone volunteered to work over the weekend on the problem and there is plenty of room to raise the rocket vertical for tests in the VAB to work out any other issues that may arise before attempting another rollout
Kerbal Space Agency
@KSA_MissionCtrl
bad news, the rocket made it almost halfway vertical before the hydraulics failed - thankfully fail-safes prevented it from crashing back down, but it will need to return to the VAB and be offloaded so repairs can be made to the carry vehicle
Kerbal Space Agency
@KSA_MissionCtrl
very nice to see others with this point of view. We are getting tired of KNN putting on talking heads that try to convince everyone the event had malicious intent, when scientists still know so little! In fact, be sure to check today's Ops Summary for an update related to this...
Kerbal Space Agency
@KSA_MissionCtrl
yes, this is a concern we share! The ongoing research project is working closely with us to monitor our progress towards launch and see if any new activity can be detected. It remains quiet so far, and there was a build-up recorded prior to The Incident last year
Kerbal Space Agency
@KSA_MissionCtrl
Mounted atop the Ascension Mk1 lifter is a test weight that masses 1t. What else is on the rocket? Hover over its image and over the dots that appear to learn more about its various parts in our Ops Tracker: ops.kerbalspace.agency (tap on touchscreens) twitter.com/lastcartridge/…
Kerbal Space Agency
@KSA_MissionCtrl
there she goes! The Ascension Mk1 is finally on its way to the launch pad to be raised vertical and hooked up to the service towers. Still lots of things that need to be confirmed working properly before launch but definitely a big milestone for the teams

@KSA_MissionCtrl
Jeb & Val have just completed their final mission for the Genesis program! Tomorrow they will officially transfer over with Bob and Bill to Ascension and begin to focus solely on training for space flight
Kerbal Space Agency
@KSA_MissionCtrl
final checkouts on the Ascension Mk1 are completed, Lead Engineer Simon reports "that's a fine looking rocket!". It will now be loaded up aboard the carry vehicle for transport out to the launch pad tomorrow
Kerbal Space Agency
@KSA_MissionCtrl
VAB crew pulled a long day in order to get the Ascension Mk1 stacked vertically by adding the test weight to the top of the fuel tank. Initial mating was troublesome and the test weight had to be modified slightly for a good fit. Final checkouts begin tomorrow
Kerbal Space Agency
@KSA_MissionCtrl
construction has completed on the Ascension service towers, shown here in their post-launch position. The arms swing in to the left to hook up to the rocket once it is on the launch pad - which it will be next week!
Kerbal Space Agency
@KSA_MissionCtrl
both Sheltered Rock and Ockr have confirmed with us they have acquisition of telemetry signal. For the first time in a long time we will be able to follow the rocket all the way through to landing - no waiting to find out what happens!
Kerbal Space Agency
@KSA_MissionCtrl
we have booster ignition and the rocket has cleared the launch base on its ascent to explore space far north of the equator! Initial boost phase will end at L+35s, pitch nominal and spin-up has begun to stabilize the rocket (Minmus is hiding in the clouds)

@KSA_MissionCtrl
no issues on departure, Val is now turning in course for bit.ly/Area_B-1F following Jeb's directions as he plots their course. Looking back from the rear-facing booster camera saw this while climbing out - look closely & you can just make out the runway threshold markers
Kerbal Space Agency
@KSA_MissionCtrl
Deuce mission is a Go for this day cycle, Jeb & Val are finishing up preflight. Above the cockpit you can see mounted the booster camera that will get to undergo some relatively light aerodynamic stress testing while the aircraft is in flight

fully exploring this region will be a goal of our first orbital probe Kerbin I, but until then we'll get what data we can from our sub-orbital missions, such as correlating data with a northward launch & flying higher with a Mk6 Block II
Kerbal Space Agency
@KSA_MissionCtrl
the data we have so far on the hazardous radiation region in space tells us three main things:
1: it extends above 580km near the equator
2: it gets "fuzzy" around the edges with a larger area extending closer to the surface
3: it stops entirely if you travel south far enough

Kerbal Space Agency
@KSA_MissionCtrl
today's K2-X test has been cancelled after further data review found it to be redundant and unnecessarily risky given that we would like to use this engine for our first Ascension Mk1 flight to meet our original schedule - which we can't do if it blows up
Kerbal Space Agency
@KSA_MissionCtrl
Ascension teams report the K2-X has passed all primary testing and want to run one more test tomorrow to really push the limits by kicking off the engine at full thrust for a 60s burn
Kerbal Space Agency
@KSA_MissionCtrl
second hot-fire test was also successful, running the engine through a Block II launch with partial thrust to start until SRB release and throttle up to full power (MaxQ during SRB burn) for the remainder. Tomorrow will be dedicated to further data review & engine inspections
Kerbal Space Agency
@KSA_MissionCtrl
nominal first hot fire test for today saw the K2-X run through a Block I launch of full thrust at takeoff with a pull-down through MaxQ regime followed by return to full thrust for the remainder of the burn. Post-testing inspection & prep for next test underway
Kerbal Space Agency
@KSA_MissionCtrl
Ascension teams report the K2-X engine is good to go for another round of testing tomorrow, which will put it through full burns simulating the flight profile of both the Block I and Block II ascents

second engine hot fire of today was another success, igniting at 15% thrust with only 5% of fuel remaining in the tanks. Next week will begin with more comprehensive reviews of test data before two final tests to close out the run by the end of the week
Kerbal Space Agency
@KSA_MissionCtrl
good first K2-X test of the day, with the engine being ignited while already throttled to 50% but only with 25% of fuel remaining to test conditions (except air pressure) where the engine could one day be made restartable while in flight
Kerbal Space Agency
@KSA_MissionCtrl
We just don’t push it past tolerances and it doesn’t run long enough to melt, tho it does go red hot. One of the things being tested is how stressed the bell gets after repeated testing, and whether any fatigue from the heating/cooling will be apparent by the end of next week twitter.com/lastcartridge/…
Kerbal Space Agency
@KSA_MissionCtrl
Lead Engineer Simon reports the K2-X is holding up just fine, so we will continue with testing tomorrow and then pause at the start of next week for our second comprehensive data review

@KSA_MissionCtrl
shortly after sunrise and KSC stands ready to resume operations as we complete our initial move back onto campus today. Will take another week or so to complete the transition but activities will pick up & a rocket will be back on the pad soon!
Kerbal Space Agency
@KSA_MissionCtrl
KSC will re-open for operations this week! We will endeavor to show the Presider that his potential "sacrifice" will not be in vain and we thank him immensely for his support. Read more on the operations restart here: kerbalspace.agency/?p=7024

@KSA_MissionCtrl
the new offices still have to be setup with equipment and everything wired up but it should be all set for our return. Although the underground areas could be used before then, pointless to do so without any ongoing operations at KSC
Kerbal Space Agency
@KSA_MissionCtrl
we can't occupy permanent structures above ground but we can continue to build them! Our new Administration Complex is complete on schedule. Original bldg rebuilt w/new & better materials, second bldg is 3rd story, with 2 levels sprawling underground (high water table)

@KSA_MissionCtrl
find out more about the Ascension Mk1 designs released earlier this week via bit.ly/OpSummary3-12-… and tell us - are you doing anything sciencey this weekend?
Kerbal Space Agency
@KSA_MissionCtrl
our legal team isn't just *our* legal team, unfortunately, so while we'd like them to get these laws rewritten and put through for review by the Assembly posthaste they do have to deal with the needs of their other clients as well
Kerbal Space Agency
@KSA_MissionCtrl
our crew have been busy the past week advising the Ascension engineers as the final design specifications for the 1.25m crew capsule were finalized. The actual design will be finalized later this year after a few months of prototyping & testing

@KSA_MissionCtrl
vessel patches for the Ascension Mk1, and once they start lifting actual payloads we will be able to also begin featuring mission patches!
Kerbal Space Agency
@KSA_MissionCtrl
it is important to note that Lift Capacity is how much mass it can push off the ground. Payload Capacity (LKO/UKO/KEO), still unknown, is how much mass it can put into a given orbit.

the fight to resume surface operations continues, get additional information on that and more via bit.ly/OpSummary3-5-18 - a relaxing weekend is wished upon all
Kerbal Space Agency
@KSA_MissionCtrl
fortunately we expect to have majority support in the Assembly as well as the backing of the Presider so hopes are high we can get all this ratified in a matter of weeks instead. Still - well played, Monolithic followers. Well played.
Kerbal Space Agency
@KSA_MissionCtrl
the High Court has ruled that the injunction against surface operations is legal, which means our team of lawyers now has to get to work writing up amendments to the current laws that will have to be cleared through Assembly. This could take months!!

upcoming Progeny launch via the Ops Tracker will still have status updates similar to the old Flight Tracker as we use the launch to code for and test the general updating of page information. Will eventually reach the point of live telemetry, hopefully by 1st Ascension launch
Kerbal Space Agency
@KSA_MissionCtrl
our Admin building has served us well, but with Ascension & Extremis set to move ops onsite this year it's going to get a bit cramped. A 780,000F expansion project will begin this month & conclude in March. In the meantime all programs will be run from KSA HQ in Umbarg

Oct focus is now on 2018-19 Extremis 1 launch window for an idea of mission requirements w/plan to announce orbital program in early Nov
Kerbal Space Agency
@KSA_MissionCtrl
delay to Extremis has a slight knock-on for our orbital program as we expected to base engine requirements on Extremis probe escape needs
Kerbal Space Agency
@KSA_MissionCtrl
tl;dr - we will launch a high-alt KerBalloon from the range monitoring vessel or KSC prior to launch to check for any wind shear conditions
