After nearly a year since the Mk7-A and numerous delays the Progeny Mk7-B finally makes its first trip up into space to test engine recovery and re-use, new reaction wheels and general flight characteristics
As the first mission of a new vehicle, this dispatch includes all the design and development leading up to launch. To skip to the launch, click here.
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
we expect several iterations as it's already known the SRM-L will need to be replaced with a more powerful solid and the SRM-XL needs to revert back to its old core, which can output up to 145kN of thrust ASL for the larger payloads that will be carried
Kerbal Space Agency
@KSA_MissionCtrl
contract evaluation by the Progenitor team is well underway for a new 0.625m solid rocket booster that will either replace the 1st and 2nd stages of the Mk7 entirely or just replace the 0.35m second stage solid booster. This will become the basis for the Mk7-B
Kerbal Space Agency
@KSA_MissionCtrl
depending on how the next Mk7-A flight goes will help to decide whether to make the full Mk7-B stack 0.625m, which is the eventual Mk7 goal but we'd like to stick to the 0.35m 3rd stage parts that are currently being manufactured as much as possible for as long as possible
Kerbal Space Agency
@KSA_MissionCtrl
lessons learned from the final Progeny Mk7-A mission have been published with the flight analysis report: kerbalspace.agency/?p=9928 - we look forward to revealing more about the Mk7-B that should fly in early 2020
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 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
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
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
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
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
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
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
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
@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…
Kerbal Space Agency
@KSA_MissionCtrl
we've used radial & nose cone chutes, now Wernher's R&D team is working on inline chutes we can stack atop the dual-segment Progeny Mk7-B booster so it can be recovered. initially this is just for post-launch assessment of the new design, but future reusability is possible
Kerbal Space Agency
@KSA_MissionCtrl
yet another new aspect of the upcoming Progeny Mk7-B has been revealed by the Progenitor team - the older MCU that ran on pre-Mk5 rockets will be upgraded to serve as a backup controller, providing redundancy during ascent for sub-orbital payloads
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
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
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
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
between launch campaigns now, the Tracking Station is taking the time to perform some maintenance and calibrations on the three 7m dishes to ensure they continue to steer and point accurately for future missions
Kerbal Space Agency
@KSA_MissionCtrl
✨KERZZAH!✨ today we get to celebrate our 11th trip around Kerbol on space ship Kerbin since the KSA began operations back in 2016. That brings our celestial odometer up to 939,011,983.1456km or nearly 1 light hour. Here's to another 106.5 day trip around the sun 🥂
Kerbal Space Agency
@KSA_MissionCtrl
several things to detail this past week - overall ops are running smooth. Rocket builds are on schedule & so is launch pad repair. R&D is quiet but that's also good in its own way. Anything you feel you might have missed can be found in our Ops Summary: kerbalspace.agency/?p=10089
Kerbal Space Agency
@KSA_MissionCtrl
CFO Mortimer is happy that we managed to squeeze out a slight profit last month! Thanks as always to our bit.ly/KSA_Patreon supporters for their help as well, with a new record for donations this month docs.google.com/spreadsheets/d…
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
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
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
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
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
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
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
although we had hoped to release a blueprint of the Progeny Mk7-B last month, issues still remain to be worked out with the rocket's current design, which places the LF/O tank in a position that leaves no good mounting options for its attachment to an existing service tower boom
Kerbal Space Agency
@KSA_MissionCtrl
additionally while it can reach perikee positive & perhaps even orbit with some more coaxing, program leads feel the design is trying too hard to satisfy too many test requirements & the 2nd stage SRB should be removed - just one of the many big decisions to be made this week...
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
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
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
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
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/?vessel=ascens…
Kerbal Space Agency
@KSA_MissionCtrl
here is the final design of the Progeny Mk7-B! It will test reliability & recoverability of the new dual-segment SRB, vector control authority, PLF heat & pressure tolerances & better energy management for reaction wheel control of heavy masses. Full res: flickr.com/gp/kerbal_spac…
Kerbal Space Agency
@KSA_MissionCtrl
unfortunately integration issues prevented us from using the Parallel Control Unit as planned to begin experimenting with backup flight computers. This will attempt to instead be integrated with the Progeny Mk7-C later this year twitter.com/KSA_MissionCtr…
Kerbal Space Agency
@KSA_MissionCtrl
Periapsis Co. has confirmed our order for 8 Boostertron IIs. 4 will be used for flights of the Mk7-B and 4 will be used for ground testing. Starting next month 2 boosters will be delivered per month (Feb[test, test], Mar[flight, test], Apr[flight, test], May[flight, flight])
Kerbal Space Agency
@KSA_MissionCtrl
the remainder of the Mk7-B has also been ordered for delivery next month to allow the upper stage of the rocket to be fully assembled & integrated so if the SRB tests in February go well the first booster delivery in March can get hooked right up for flight ASAP
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
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
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
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
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
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
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
cargo airship has arrived with our first Boosterton II dual-segment SRB aboard, which will be offloaded at the Support Village warehouse then driven over to the VAB for initial checkouts. After ensuring it is undamaged from transport it will be mounted for static fire next week
Kerbal Space Agency
@KSA_MissionCtrl
did anyone happen to notice the horizontal test stand getting set up yesterday while the MLP was rolling out of the VAB? Final preparations are currently underway for SRB static fire later today, targeting ignition @ 16:00 UTC
Kerbal Space Agency
@KSA_MissionCtrl
🚨AAAHHWWHOOOOOOO🚨
warning horn has sounded, crews evacuated from the launch pad & the horizontal test stand will shortly trigger ignition of the dual-segment Boosterton II held within its grasp. This will be the 1st ever test firing - no underground facilities can handle this

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
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
Dhumla cargo aircraft has landed, carrying this month's second & final Boosterton SRB for test firing. After it is unloaded the Kerbin I recovery crew will load up with their equipment and fly out to the Kongo to prepare to hunt down the impending impact site
Kerbal Space Agency
@KSA_MissionCtrl
preliminary VAB inspection of the Boosterton II fired earlier this month shows it to be in good shape and we will now send back to Periapsis Co. for even more examination and then, if all checks out, recasting. We hope to test fire it again in April
Kerbal Space Agency
@KSA_MissionCtrl
another successful test firing of the latest Boostertron II was carried out today. We will get two more next month; the 1st one will be one final test to ensure manufacturing reliability, if good the 2nd will be integrated for flight with the first Progeny Mk7-B in late March
Kerbal Space Agency
@KSA_MissionCtrl
a historic month draws to a close. Recap the Kerbin I mission, learn more about our upcoming missions and what else transpired this past week over at the Ops Summary: kerbalspace.agency/?p=10499
Also, now all the parties
🎆🎉🎊🎇
Also, now all the parties
🎆🎉🎊🎇
Kerbal Space Agency
@KSA_MissionCtrl
production of Boostertron II SRBs has ramped up over at Periapsis Co. and we already have this month's test article for static fire later this week, after which we could have a Progeny Mk7-B launch date locked in if all goes well!
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
and with the 3rd successful SRB test firing early today the Progenitor team have locked in the first Progeny MK7-B launch date for 3/26 @ 21:32 UTC! Final mission details are still being worked out, expect an Ops Tracker entry sometime next week
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
the Ascension Mk1 delay will not have a knock-on effect for the Progeny Mk7-B mission, which uses the same launch pad but in a different configuration. Pad crews will have no problem getting the GSE turned around in the following 6 days to be ready for the next launch
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
💫 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
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
our next launch remains on schedule as the VAB completed stacking the Progeny Mk7-B today. Now laid back horizontal, final close out procedures have begun, which will continue into tomorrow before the rocket is loaded up onto the carry vehicle for rollout early the following day
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
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
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
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
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
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
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
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
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
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
damage assessment of the horizontal test stand shows that it will only require minor repairs over the next 2 weeks that will hopefully take no longer than the team at Periapsis Co. looking into the failure & getting another used booster ready for the next test firing
Kerbal Space Agency
@KSA_MissionCtrl
final major hurdle in getting back to rocket flight has been cleared with the full review & analysis of the orbital Kerbin I mission completed kerbalspace.agency/?p=10905 Now Progenitor & Ascension teams will spend May on upcoming mission plans
Kerbal Space Agency
@KSA_MissionCtrl
work continues to get our rocketry programs back to flying, but there is still a ways yet to go. Learn more about what lies ahead and take a look back at what transpired over these past two weeks: kerbalspace.agency/?p=10927 Everyone have a nice weekend!
Kerbal Space Agency
@KSA_MissionCtrl
VAB construction remains on hold until at least next month while procedures remain under review. The first completed Progeny Mk7-B has been re-examined for another round of final checks and the next booster to be assembled for flight is awaiting inspection
Kerbal Space Agency
@KSA_MissionCtrl
financial report for April is now available (docs.google.com/spreadsheets/d…) are we happy with this months earnings? Not really, because we want to be spending this money on space missions! We continue be thankful though for our bit.ly/KSA_Patreon contributors!
Kerbal Space Agency
@KSA_MissionCtrl
our horizontal test stand has been repaired but the kerbs at Periapsis Co. are still working on getting another refurbished booster ready for us to test, hopefully later this month. This will be from the second test conducted back in February
Kerbal Space Agency
@KSA_MissionCtrl
we've received the 1st of 2 new Boostertron II SRBs that will arrive this month to fly future Progeny Mk7-B missions. This will round out the initial order purchased back in January however more are already being assembled for the upcoming Ascension Mk3
Kerbal Space Agency
@KSA_MissionCtrl
our bi-weekly Ops Summary has more information on Alaba's latest trajectory analysis and also details on a recent announcement that Umbra Space Industries, long-time supplier for our Progenitor rockets, has gone bankrupt! kerbalspace.agency/?p=10937
Kerbal Space Agency
@KSA_MissionCtrl
rail depot at the end of the tracks coming from Umbarg has been completed, making for a high-capacity cargo link between us and the nearest underground cavern. The train will also be used occasionally to transport kerbs and large rocket parts
Kerbal Space Agency
@KSA_MissionCtrl
events late last week postponed our bi-weekly Ops Summary to allow us to share better details, unfortunately the news from USI is not good & has temporarily suspended Progeny launches. Ascension looking better, but still behind sched. More details: kerbalspace.agency/?p=10993
Kerbal Space Agency
@KSA_MissionCtrl
today's test firing of a recast SRB on the horizontal test stand (the 2nd one tested in Feb) went better than the first - it didn't explode! Early data analysis shows however that thrust was diminished rapidly towards the end of the burn, indicating casing issues still remain
Kerbal Space Agency
@KSA_MissionCtrl
May finances have been published (docs.google.com/spreadsheets/d…). The centrifuge has been paid off and we have built up a bit more spending capital to hopefully finally put to use this month. We hope to lose money in June cause then we'd be exploring hard!
Kerbal Space Agency
@KSA_MissionCtrl
once we heard Progeny launches were suspended due to the legal battle involving USI we filed an appeal but it was just denied, leaving the Progenitor program to just continue building the 4 Mk7-Bs already ordered & hoping this mess is cleared up soon so they can launch
Kerbal Space Agency
@KSA_MissionCtrl
we're ramping rocket operations back up! Sadly Progenitor remains sidelined but Ascension is free to fly and we have three launches in the queue:
6/23 @ TBD - Mk1 (unkerbed)
7/16 @ TBD - Mk1 (Spc Bob)
TBD August - Mk2
Save the dates! More details in the coming days 🚀✨
6/23 @ TBD - Mk1 (unkerbed)

Save the dates! More details in the coming days 🚀✨
Kerbal Space Agency
@KSA_MissionCtrl
work is all set to resume in the VAB next week. Progeny Mk7-B assembly atop the 4 boosters will continue while we await launch permission. This month's rocket just needs to be stacked for final closeouts. Bob's ride still has a lot of prep for next month
Kerbal Space Agency
@KSA_MissionCtrl
news just came in that Umbra Space Industries, our long-time partner for Progenitor rocket parts that went bankrupt earlier this year, has been bought up - a deal that has been rumored for some time now. More information is expected to be released next month
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
over to the side of the VAB where the Progenitor rockets are assembled two Progeny Mk7-Bs are now completed, with the remaining two Boostertrons waiting on parts to be delivered by USI that were delayed due to their bankruptcy. Back to back launches soon? We hope so too!
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
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
we finally know the name of our new rocket supplier - Luciole! They will be meeting with us later this month to discuss plans for future Progenitor rockets, are committed to a 0.625m orbital launch vehicle & are also continuing to develop a 0.625m aerospike engine
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
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'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
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
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
while we've set initial dates for the first two (of four) Mk7-B launches, mission objectives are still being finalized now that the Mk7-C is shelved and there will not be a direct continuation to the Mk8. Expect time/date confirmation & Ops Tracker mission details next week
Kerbal Space Agency
@KSA_MissionCtrl
Progeny Mk7-B launch dates & times confirmed!
Flight 1: 8/12 @ 17:23 UTC
Flight 2: 8/26 @ 18:11 UTC
Next 2 will launch Oct, not just cause they still need to be assembled but to give us time for any adjustments based on these initial flights. More info: bit.ly/Ops_Tracker

Lead Engineer Simon reports that the first Progeny Mk7-B has passed its final flight readiness checks and has been loaded up onto the carry vehicle. We remain on schedule for rollout and WDR tomorrow ahead of launch attempt Wed ops.kerbalspace.agency/?vessel=progen…
Kerbal Space Agency
@KSA_MissionCtrl
looks like we should have checked out the carry vehicle as well as we did the rocket - rollout delayed until tomorrow & launch pushed to Thurs @ 17:27 UTC. We could rollout & launch in a single day but with a new rocket FD Lanalye says she wants a full day for pre-launch checks
Kerbal Space Agency
@KSA_MissionCtrl
the rocket is nearing the pad as the carry vehicle plods along at just 7m/s - faster than when carrying a heavier Ascension load. It will be lifted vertical, mounted to the engine clamp, then the service tower, then the 4th support leg will be installed
Kerbal Space Agency
@KSA_MissionCtrl
pre-launch checks going well. Wet Dress Rehearsal completed, no issues, launch support arms were now just tested, actuation was good. They will pull back seconds before launch, otherwise they could obstruct the guidance fins. Example from Mk7-A launch: youtube.com/watch?v=9x8MJL…
Kerbal Space Agency
@KSA_MissionCtrl
the support arms keep the rocket stable against any sudden wind gusts during the 2min terminal count when the service tower is no longer connected. The 0.625m SRB does not sit fully within in the 1.25m launch clamp so it does not provide good lateral support on its own
Kerbal Space Agency
@KSA_MissionCtrl
FD Lanalye says she wants one more day of checking out the rocket and testing new control systems that were installed between this mission and the last unkerbed flight back in June. Always better safe than RUD - new launch time has been set for 8/14 @ 17:30 UTC
Kerbal Space Agency
@KSA_MissionCtrl
another day of checkouts gets underway as FD Lanalye and her team work to get new flight systems to fully cooperate with the rocket and ground service equipment. When it works it works great, but it doesn't always work 100%
Kerbal Space Agency
@KSA_MissionCtrl
Ops Director @DKerman_KSA has approved all readiness reports from Simon & Lanalye - we are 🚀 GO 🚀 for launch attempt tomorrow! Weather forecast 60% favorable - today was of course nicer. Pre-launch operations are scheduled to begin at 12:45 UTC ops.kerbalspace.agency/?vessel=progen…

[L-4h45m] prelaunch ops are GO with updated weather forecast improving conditions to 80%. Launch teams are dispersing to get ready for their various duties. Countdown is slightly condensed as rocket remained fueled after WDR on Wed. Expect updates at these milestones:
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h15m] Flight Director Lanalye has gathered her B team of launch controllers for their final pre-flight briefing. Primary mission goals are:
• Recover both stages
• Reaction wheel control
• Re-light 2nd stage in space
Mission overviews:
• Recover both stages
• Reaction wheel control
• Re-light 2nd stage in space
Mission overviews:
Kerbal Space Agency
@KSA_MissionCtrl
Here's a look at the mission animated, with the SRB falling close to KSC while the second stage flies further downrange, talking to all major ground stations to ensure we have backup data collection. 2nd propulsion not shown, will be triggered by controllers prior to apokee
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h45m] controllers are on console, launch crew is at the pad, preflight operations are now fully underway to prepare the rocket for lift off. Booting up flight computer - you can review mission control code here: bit.ly/AFCS_ChangeLog
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h40m] pre-launch proceeding on schedule, no issues raised so far. Rocket is woke & configured, launch crew have ensured all is as they left it after WDR. Pad now being cleared out so engine system tests can be performed
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h30m] all the work done over the past 2 days continues to give us no issues to work & preflight is now completed, rocket stands ready! Word has been passed along from MSV vessels that the Aldeny is on station in good sea conditions. Booster recovery vessel has been launched
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h20m] surface conditions have continued to improve but another check of high-altitude winds is needed so a second high-altitude KerBalloon has been released with enough time to ascend up past 18km well before analysis needs to be complete prior to final polling at L-5min
Kerbal Space Agency
@KSA_MissionCtrl
[L-45m] moving into the final stage of prelaunch operations, launch team preparing for mission rehearsal to ensure all systems are properly configured. Pad crew are hooking up pressurized gas tanker to the service tower and then making final clear out
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] surface weather continues to hold and we are GO to proceed into the final countdown, the point at which we would need to back up to if a hold is called. Pad is locked down, Range Safety Officer working to confirm launch corridor is clear
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] RSO has confirmed clear air, land and water. Rocket is ARMED, Flight Termination System ACTIVE. Despite this being an inaugural launch, small crowd outside today. All visitors must remain in designated areas
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] we have a GO from all stations as final polls wrap up and launch permission is given by @DKerman_KSA. Service tower boom is unlocked for retraction, FTS already on internal power and the Automated Flight Control System is preparing to switch over to batteries as well
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] AFCS has activated to take control of the rocket and begin terminal countdown procedures. Service boom has swung away, rocket is draining internal power and on RF comms, both being checked ahead of primary station polls at L-30s
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] the minutes tick down into seconds! If you're not already watching, the live ascent telemetry will load in the Ops Tracker after we pass primary station polling - tune in now: ops.kerbalspace.agency/?vessel=progen…

@KSA_MissionCtrl
good ignition of the Boostertron II and we have lift off! The first Progeny Mk7-B screams skyward with an initial TWR of 3 as the guidance program immediately kicks in to angle the fins and begin pitching over downrange. Go Progeny Go!
Kerbal Space Agency
@KSA_MissionCtrl
rocket had a rough time pushing through MaxQ but did become more stable as pressure eased and air continued to thin. BECO also occurred almost 5km lower than expected, likely due to way larger drag losses than predicted due to excess fin movement
Kerbal Space Agency
@KSA_MissionCtrl
2nd stage burn completed, with the flight computer terminating it early to save enough fuel for our restart attempt while still pushing out of the atmosphere. Not the ideal flight we had planned but still making do with the under-performing initial ascent
Kerbal Space Agency
@KSA_MissionCtrl
we've had a successful restart of the Ospray engine while in space! This isn't the first time we've restarted an engine in flight but is the first time this particular engine has been restarted in flight. Without air pressure, gas plume from engine expands rapidly
Kerbal Space Agency
@KSA_MissionCtrl
rocket is through apokee (planned was ~160km) & controllers will use the reaction wheels to get it slowly turned around retrograde before hitting the atmosphere again. MSV Aldeny should have already begun steaming westward after picking up the rocket low over the horizon
Kerbal Space Agency
@KSA_MissionCtrl
rocket was able to re-orient properly in time but coming in so shallow questionable whether it will remain upright into air stream. Definite that reaction wheels cannot hold it there. Relatively slow speed means we may hold comms until the horizon
Kerbal Space Agency
@KSA_MissionCtrl
we just lost comms due to plasma blackout & rocket will soon fall over the horizon. Last-known position puts it ~90km from the planned recovery zone, so it will take MSV Aldeny almost 3 hours to reach & begin search operations
Kerbal Space Agency
@KSA_MissionCtrl
while we await word on recovery of the second stage, good news from closer downrange as the first stage booster is being hooked up for tow back to shore, where it will be hauled out then shipped off to Periapsis Co. to see whether it could possibly be re-used in the future
Kerbal Space Agency
@KSA_MissionCtrl
still awaiting word from the Aldeny, which will have a decent area to search for the beacon signal given currents could have carried the rocket several kilometers away from the estimated landing area by now. Post-launch operations here at KSC are wrapping up
Kerbal Space Agency
@KSA_MissionCtrl
we finally have word on the second stage - it was recovered, but not fully intact. The lower half of the fuel tank & engine were missing. Unfortunately engine recovery was a primary goal & thus we will have to mark this mission as a failure, but still mostly successful
Kerbal Space Agency
@KSA_MissionCtrl
while today was slightly disappointing, we're still happy to finally get to start working through the Progeny MK7-B launch campaign! Recap the major events from the past two weeks in our Ops Summary if you need to quickly catch up: kerbalspace.agency/?p=11190
Kerbal Space Agency
@KSA_MissionCtrl
more photos from the Mk7-B flight. Not going as high as planned, there was no time to "look around" so we just got whatever the cameras happened to be pointing at while thrusting prograde & re-orienting, facing retrograde. Descriptive text is included for each image
Kerbal Space Agency
@KSA_MissionCtrl
rocket breakup messed with sensor wires running up the fuel tanks and crashed the flight computer attempting to access those sensors a few seconds after signal loss, so telemetry data is incomplete but as always still available for review: docs.google.com/spreadsheets/d…
Kerbal Space Agency
@KSA_MissionCtrl
the booster cam was not recording video fast enough to really appreciate just how wibbly wobbly the rocket was on intial ascent, so to the ground tracking camera we go. Everyone is still amazed it managed to hold together, altho this likely contributed to the re-entry break-up
Kerbal Space Agency
@KSA_MissionCtrl
flight analysis report on the first progeny Mk7-B launch has been published: kerbalspace.agency/?p=11203 TL;DR - we might hot-fire 2nd stage this next flight to get higher apokee & guidance control tweaked to hopefully lessen roll-shake on initial ascent
