Lowering the first stage TWR to 2 failed to generate enough thrust to keep the rocket pointed east, and the flight was terminated shortly after launch when the rocket began to fly west over KSC

@KSA_MissionCtrl
senior staff & crew gathering in the Admin bldg for 1st daily ops meeting in 2wks! Been a struggle but we are gradually returning to normal

@KSA_MissionCtrl
FD Lanalye reports Launch Ctrl primaries up & rdy for launch in Aug, may still be missing redundancies but that won't stop launch attempt
Kerbal Space Agency
@KSA_MissionCtrl
any lack in redundant systems only means a greater chance of a hold prior to launch, as a failed primary will have no backup to fall back on

@KSA_MissionCtrl
Lead Engineer Simon just brought everyone up to speed on VAB & HAB status - both are set to resume work on Deuce and Progeny Mk4s this week
Kerbal Space Agency
@KSA_MissionCtrl
VAB had a great 1st day back at work, assembly of both new Mk4 rockets are moving along well. Simon & Bill were both there wrenching as well
Kerbal Space Agency
@KSA_MissionCtrl
Simon has our final 2 Progeny Mk4 launches, save the dates!
bit.ly/ProgenyMk4-4 @ 8/4 14:55 UTC
bit.ly/ProgenyMk4-5 @ 8/8 21:09 UTC
bit.ly/ProgenyMk4-4 @ 8/4 14:55 UTC
bit.ly/ProgenyMk4-5 @ 8/8 21:09 UTC
Kerbal Space Agency
@KSA_MissionCtrl
both Mk4 payloads are being closed up today so the rockets can be topped off tmrw. VAB handling the dual-assembly without any issues so far
Kerbal Space Agency
@KSA_MissionCtrl
Simon reports both Mk4 rockets have been topped off, they look great next to one another! Yes, a simultaneous launch would be cool but, no
Kerbal Space Agency
@KSA_MissionCtrl
moving into post-launch cleanup, VAB workers also getting back to bit.ly/ProgenyMk4-5, which will undergo final closeouts today
Kerbal Space Agency
@KSA_MissionCtrl
5th Mk4 is ready for rollout on Monday reports Simon. bit.ly/ProgenyMk4-4 has final update. Ops summary: bit.ly/OpsSummary7-31…
Kerbal Space Agency
@KSA_MissionCtrl
with the first hint of dawn on a moonless night, the KerBalloon UTVs depart w/Bill in the lead. They will be covering familiar terrain in the low light
Kerbal Space Agency
@KSA_MissionCtrl
also being done this day cycle is the roll-out & mounting of bit.ly/ProgenyMk4-5 to the launch base, Bill bummed he can't take part
Kerbal Space Agency
@KSA_MissionCtrl
KB crew has setup camp after an uneventful 132km traverse & Progeny Mk4 is mounted, undergoing final readiness checks via Launch Control
Kerbal Space Agency
@KSA_MissionCtrl
other areas of the KSC have also been ensuring they are rdy for launch ops tomorrow, including Tracking Stn which now has our new dish setup
Kerbal Space Agency
@KSA_MissionCtrl
tomorrow the VAB dish will also gather launch telemetry, though not as primary receiver, to fully test out its signal reception & tracking
Kerbal Space Agency
@KSA_MissionCtrl
Launch Control reports the rocket mount is good & now @DKerman_KSA just has to sign & file a bunch of paperwork - his favorite thing! (Not)
Kerbal Space Agency
@KSA_MissionCtrl
it's an end to regular KSC ops for today & all Progeny Mk4 launch readiness items have been cleared. We are 🚀 GO FOR LAUNCH 🚀 tomorrow!!
Kerbal Space Agency
@KSA_MissionCtrl
as with our previous late-day launch, we will still begin preparations early @ 15:09 UTC to give us extra time in case of preflight issues

@KSA_MissionCtrl
[L-6h] launch prep officially begins! Updates to be expected during these major events. Wx data is collected from Umbarg, Kravass & airships
Kerbal Space Agency
@KSA_MissionCtrl
we are going to say that a Kerbolar eclipse on launch day is good luck. Top-bottom Moho, Sarnus & Eve are also visible in the darkened sky
Kerbal Space Agency
@KSA_MissionCtrl
[L-5h30m] we continue to be treated to favorable weather conditions thruout the region - no storms/precipitation nearby. GO for preflight!
Kerbal Space Agency
@KSA_MissionCtrl
[L-5h] sticking to sched, launch briefing completed & preflight underway. Ascent will be the same as last launch, depicted via this graphic
Kerbal Space Agency
@KSA_MissionCtrl
we may alter our ascent profile further with the Mk5 but for now we only want to see how changes to lower booster thrusts affects the flight
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h45m] GO for tanking, loading 109kg of liquid propellants to the 3rd stage. So far we have encountered no issues during preflight
Kerbal Space Agency
@KSA_MissionCtrl
[L-4h30m] tanks are topped off, allowing us to begin work checking the rocket fuel systems & begin monitoring fuel levels to ensure no leaks
Kerbal Space Agency
@KSA_MissionCtrl
[L-3h45m] all nominal, we are moving on to engine/ignition checks, pad being cleared of crew out to 300m for safety in event of explosion
Kerbal Space Agency
@KSA_MissionCtrl
sun is setting, Mun not far behind. VAB dish is oriented & ready for testing. Hopefully this great weather continues into the next day cycle
Kerbal Space Agency
@KSA_MissionCtrl
[L-2h15m] after a routine & uneventful preflight we are now STANDING BY at launch readiness, continuing to monitor the rocket for any issues
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h30m] once again swapping roles, MSV Tongjess is holding station 15km southeast to monitor the eastern range stays free of wayward boats
Kerbal Space Agency
@KSA_MissionCtrl
[L-1h] successful check-in with MSV Lymun 150km downrange, skip comms working great today. Bob & Jeb both tagged along w/recovery crew
Kerbal Space Agency
@KSA_MissionCtrl
[L-45m] with no issues still on the board & both MSVs in place Flight Director Lanalye can run her team thru a full launch dress rehearsal
Kerbal Space Agency
@KSA_MissionCtrl
Cdr Val is taking the place of a launch controller who fell ill yesterday. Only a minor monitoring role. Still, she's excited to take part
Kerbal Space Agency
@KSA_MissionCtrl
[L-30m] Wx remains good, we have a GO to begin final countdown! Skies seem to be mostly clear, we'll have a better look as sun rises higher
Kerbal Space Agency
@KSA_MissionCtrl
[L-20m] still in touch with Lymun, they report Bob, Jeb & the rest of the crew are ready to launch for recovery after rocket clears horizon
Kerbal Space Agency
@KSA_MissionCtrl
[L-15m] Tongjess reports eastern range clear, RSO is GO to ARM rocket, FTS active. Really no reason any boats should ever be nearby the Cape
Kerbal Space Agency
@KSA_MissionCtrl
to those in the viewing areas remember: 1st stage is only boosting @ 2Gs so nobody panic when you don't see the rocket fly fast off the pad
Kerbal Space Agency
@KSA_MissionCtrl
Scattered clouds, but clearing well - we're looking at an on-time launch! Coming up on final all-stations poll, issues board remains clear
Kerbal Space Agency
@KSA_MissionCtrl
[L-5m] Wx GO, Range GO, Flight GO, Tracking GO, Launch clearance: authorized! 🚀GO PROGENY!!🚀 Barring tech issues we are committed to launch!
Kerbal Space Agency
@KSA_MissionCtrl
[T-2m] AFCS active, ready to fire the rocket at precisely 19:09:00.0 UTC. Umbilicals severed, rocket is on internal power, EC drain nominal
Kerbal Space Agency
@KSA_MissionCtrl
[T-1m] can tune into bit.ly/ProgenyMk4-5 at any time for live updates but why not right now if you haven't already? Here. We. Go!
Kerbal Space Agency
@KSA_MissionCtrl
Liftoff!! How slow can we go? The rocket has left the launch base at only 2Gs. As with our last launch, lift at the nose could be an issue
Kerbal Space Agency
@KSA_MissionCtrl
the RSO was forced to activate the Flight Termination System at L+17s as the rocket was climbing westward over the KSC shortly after launch
Kerbal Space Agency
@KSA_MissionCtrl
we had some lighter pieces of debris drifting down towards spectator areas, but warning sirens went off & everyone pulled back past the VAB
Kerbal Space Agency
@KSA_MissionCtrl
post-termination procedures well underway, Launch Ctrl ensuring all console data preserved & UTVs patrolling for any still-burning debris
Kerbal Space Agency
@KSA_MissionCtrl
.@Three_Pounds we went 8-6-4-2 so it's been a steady decrease, we've just finally hit the low-end limit. Suspected <2G would be it, but now we know!
Kerbal Space Agency
@KSA_MissionCtrl
MSVs Lymun & Tongjess are moving off station w/our thx. Bob & Jeb are bummed they don't get to take part in a payload recovery operation
Kerbal Space Agency
@KSA_MissionCtrl
post-termination & post-launch ops winding down. Disappointing but at the same time good to know we have found some more limits for Progeny
Kerbal Space Agency
@KSA_MissionCtrl
launch photo from the HAB roof. We should have more details on the launch failure later this week, after a full data review is completed
Kerbal Space Agency
@KSA_MissionCtrl
while KerBalloon preps for a mission today, Progenitor will be reviewing launch data. Not much to cover, so we expect a report by tomorrow
Kerbal Space Agency
@KSA_MissionCtrl
launch analysis complete for the final Mk4 flight. As suspected, nose lift to blame although the launch rail may have also struck the rocket
Kerbal Space Agency
@KSA_MissionCtrl
check out a comparison of the last 3 Mk4 launches for an idea of how TWR affects the rocket during initial ascent youtube.com/watch?v=SEvVtM…
Kerbal Space Agency
@KSA_MissionCtrl
note how it's not just the speed that is affected but burn time as well, 6Gs burnt out in 6s, 4Gs in 9s & 2Gs took 17s - big diff from 4-2!
