00:00:00.000 --> 00:00:02.000


00:00:02.000 --> 00:00:11.000
George Diller/Ares I-X Commentator:  T-10... nine... eight... seven... six... five... four... three... two... one.

00:00:11.000 --> 00:00:43.000
Ignition and liftoff of Ares I-X, testing concepts for the future of new rocket design.

00:00:43.000 --> 00:00:52.000
Marc Lavigne/Ares I-X Telemetry Engineer:  
Altitude now 2 miles. Camber pressure now 
tapering off, as designed.

00:00:52.000 --> 00:00:58.000
Vehicle is aligning itself with the planned trajectory.

00:00:58.000 --> 00:01:12.000
We've passed Mach 1 and we're now passing max Q. We have our max Q system ID maneuver PTI engaged.

00:01:12.000 --> 00:01:24.000
Now passing Mach 2. Vehicle now 10 miles altitude, downrange distance 8 miles, and velocity of 1,540 mph.

00:01:24.000 --> 00:01:29.000
Plus 80 seconds, we've started our 
supersonic large aptitude ID maneuver PTI.

00:01:29.000 --> 00:01:45.000
We see the response. And we've started the last PTI maneuver, structural mode ID.

00:01:45.000 --> 00:01:56.000
And we've passed T+ 105 seconds. 
Vehicle's now traveling Mach 4, 20 miles 
altitude, downrange distance 32 miles.

00:01:56.000 --> 00:02:08.000
The SRM tailoff is observed. Burnout.
Our APUs have shut down.

00:02:08.000 --> 00:02:16.000
CRDs have shut down. Medium fire. And 
sep, we show a sep and a tumble motor 
ignition.

00:02:16.000 --> 00:02:21.000
And we can also confirm on video we see both parts of the vehicle tumbling.

00:02:21.000 --> 00:02:34.000
The first stage as well as the upper stage -- successful separation. Good, clean signal all the way. T+150 seconds.

00:02:34.000 --> 00:02:41.000
