00:00A gas closeout
00:02has also begun
00:04just now, so we're isolating
00:06all the feed lines for the different gas
00:08systems from the Falcon 9
00:10rocket. Those gases will then
00:12get vented overboard through umbilicals
00:14and the strong back.
00:16And actually, if you listen closely, you can hear
00:18some of that venting from the vehicle.
00:20Obviously, rockets are very loud
00:22and sound can impart pressure
00:24loads back on the rocket itself.
00:26A ton of water absorbs and prevents
00:28the sound from hitting the structure and
00:30reverberating back onto the vehicle.
00:32FTS is armed and Falcon 9 is in startup.
00:35Dragon is in countdown.
00:39Dragon's flight
00:40computer is now in countdown
00:42and configured for launch.
00:44Now less than one minute away from the launch
00:46of Crew 12. Dragon, SpaceX, go for launch.
00:49Great call out there.
00:50Go for launch. At the time of launch,
00:52Space Station. Dragon, we are go for launch.
00:57At the time of launch, Space Station
00:59will be flying 260 statute miles
01:01over the South Pacific Ocean
01:03east of New Zealand.
01:05SpaceX is go. Crew is go.
01:06Let's watch as Falcon 9 takes
01:08Crew 12 out into space.
01:15T-minus 15 seconds.
01:20T-minus 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, ignition and liftoff.
01:33Go Falcon, go Dragon, and Godspeed Crew 12.
01:37And liftoff. Freedom flies
01:40bound for the International Space Station.
01:431.7 million pounds of thrust
01:45now propelling Falcon 9 and Crew 12.
01:49Vehicle is pitching downrange
01:51and all nine Merlin vehicles have lit.
01:53We're getting good call outs
01:54on the first stage performance
01:56and propulsion so far.
02:03T-plus 30 seconds
02:04into the Crew 12 mission
02:06on board Dragon and Falcon 9.
02:09Vehicle is going to throttle down
02:11in preparation for a max-q.
02:13That's the largest structural load
02:14that the vehicle will see on ascent.
02:17Power until on train nominal.
02:19Good call outs there.
02:20Stage one throttle down.
02:22There's that call out
02:23for stage one throttle down.
02:25Pass through max-q
02:26in a few seconds here.
02:29Max-q.
02:31Great news.
02:32We have passed through max-q.
02:35Vehicle is supersonic.
02:39That call out
02:40that the vehicle is supersonic
02:41means it's traveling faster
02:43than the speed of sound.
02:44Stage one throttle up.
02:46Stage one now throttling up.
02:50One bravo.
02:52That call out for one bravo
02:54means we're in the second
02:55and final abort mode
02:56for the first stage.
02:58Continuing to get good performance.
03:00The crew is now
03:01already pulling over two G's.
03:04Next up,
03:04we'll have a couple events
03:05happening in rapid succession.
03:08First is that engine chill
03:10on the second stage
03:11and back engine.
03:12And then we'll have MECO
03:14or main engine cutoff
03:15where the nine engines
03:16on the first stage
03:17will cut off
03:18ahead of the first
03:19and second stages
03:20separating from one another.
03:22Then the single Merlin vacuum engine
03:24on the second stage
03:25will ignite,
03:26continuing to carry
03:27Crew-12 to orbit
03:28while the first stage
03:29begins its journey
03:30back to Earth.
03:33The nine Merlin engines
03:36are starting to thrall down
03:37and standing by
03:38for MECO
03:39or main engine cutoff.
03:40Stage one throttle down.
03:42There's that call out.
03:43and in just a few seconds here,
03:47we will have MECO
03:48stage separation.
03:49Stage one flip maneuver
03:50for the booster
03:51to make its way back
03:52to Earth.
03:53SCS-1
03:54and the start
03:55of the boost back burn.
03:58MECO.
03:58Q alpha.
04:01Copy.
04:01Two alpha.
04:03Stage separation confirmed.
04:08End execution.
04:14And incredible views.
04:16We've had MECO
04:17stage separation.
04:18You can see that booster
04:19coming back down to Earth
04:21and that MVAC ignition,
04:23that MVAC engine
04:24has ignited,
04:25which you can see clearly.
04:27where we...
