George Diller/Ares I-X Commentator: T-10... nine... eight... seven... six... five... four... three... two... one.
Ignition and liftoff of Ares I-X, testing concepts for the future of new rocket design.
Marc Lavigne/Ares I-X Telemetry Engineer: Altitude now 2 miles. Camber pressure now tapering off, as designed.
Vehicle is aligning itself with the planned trajectory.
We've passed Mach 1 and we're now passing max Q. We have our max Q system ID maneuver PTI engaged.
Now passing Mach 2. Vehicle now 10 miles altitude, downrange distance 8 miles, and velocity of 1,540 mph.
Plus 80 seconds, we've started our supersonic large aptitude ID maneuver PTI.
We see the response. And we've started the last PTI maneuver, structural mode ID.
And we've passed T+ 105 seconds. Vehicle's now traveling Mach 4, 20 miles altitude, downrange distance 32 miles.
The SRM tailoff is observed. Burnout. Our APUs have shut down.
CRDs have shut down. Medium fire. And sep, we show a sep and a tumble motor ignition.
And we can also confirm on video we see both parts of the vehicle tumbling.
The first stage as well as the upper stage -- successful separation. Good, clean signal all the way. T+150 seconds.
