00:00:00.000 --> 00:00:04.000
George Diller/OSTM/Jason-2 Launch Commentator: Nine...Eight...Seven...Six

00:00:04.000 --> 00:00:05.000
Five

00:00:05.000 --> 00:00:06.000
Four

00:00:06.000 --> 00:00:07.000
Three

00:00:07.000 --> 00:00:09.000
Main engine start.

00:00:09.000 --> 00:00:09.000
Two

00:00:09.000 --> 00:00:10.000
One

00:00:10.000 --> 00:00:19.000
and liftoff of the Delta II with Jason-2 for the Ocean Surface Topography Mission, measuring sea level from space.

00:00:19.000 --> 00:00:30.000
(Rumbling)

00:00:30.000 --> 00:00:43.000
Mission Control: Solid motors reaching their peak chamber pressures.

00:00:43.000 --> 00:00:52.000
First stage has worked its way out of the liftoff transients. Main engine, verniers, and solid motors continue to burn well.

00:00:52.000 --> 00:01:05.000
We have exceeded Mach-1. And now exceeded Max-Q.

00:01:05.000 --> 00:01:24.000
First stage altitude disturbances are nominal. Reaching solid motor burnout of the three solid motors.

00:01:24.000 --> 00:01:35.000
Vehicle now at an altitude nine nautical miles. Downrange distance 11.

00:01:35.000 --> 00:01:43.000
Coming up on T plus 85 seconds.

00:01:43.000 --> 00:01:49.000
Main engine and verniers continue to burn well. Very solid chamber pressures there.

00:01:49.000 --> 00:01:55.000
And we?re coming up on solid motor jettison. Yes, confirmed solid motor jettison. All three.

00:01:55.000 --> 00:02:03.000
We?re looking at the normal roll disturbances at solid motor jettison. Vehicle now at a velocity of 1,200 miles per hour.

00:02:03.000 --> 00:02:04.000
