T+40 seconds. First stage propulsion looks good.

All nine Merlin 1D+ engines producing over 1.5 million pounds of thrust.

MaxQ all nominal so far

ZachS09 · « **Reply #248 on:** 12/15/2017 02:38 pm »

T+1 minute, 5 seconds. Going through Mach 1.

Coming up in about ten seconds will be Max-Q.

90 seconds into the flight.

First stage Main Engine Cut-Off is scheduled for 2 minutes, 21 seconds. Stage separation will occur four seconds later followed by ignition of the MVac engine eight seconds afterwards. From there, the first stage will begin its boostback burn five seconds after MVac engine start.

T+2 minutes. Main engine throttling in work to limit acceleration stresses.

And there's MECO-1. We've separated the stages and the first stage is flipping to boostback burn attitude.

Second stage engine start has occurred as part of a 387-second orbit insertion burn.

Stage 1 boostback burn has started. This will null all of the first stage's horizontal velocity and put its impact point over LZ-1.

T+3 minutes.

Second stage propulsion looks good.

3 minutes into the mission.

Stage 1 boostback burn has ended.
