00:00:01,000 --> 00:00:06,200
JESSICA RYE: T-minus 10, nine, eight, seven, six, five, four, three, two, one.

2
00:00:12,000 --> 00:00:20,533
We have ignition and liftoff of the Delta II rocket, carrying THEMIS, NASA's revolutionary journey to study the Northern Lights.

3
00:00:26,000 --> 00:00:32,133
Everything continues to look good with the Delta II rocket with the THEMIS payload on board.

4
00:00:37,000 --> 00:00:44,266
Nine solid rocket strap-on boosters are burning fine and the spacecraft is on its way to its intended target.

5
00:00:54,000 --> 00:01:01,200
VOICE: All solid motors have reached their peak chamber pressure and now beginning to taper off as expected.

6
00:01:02,000 --> 00:01:09,533
T+48 seconds, we've passed "max Q." All solid motors burning symmetrically, now starting their burnout phase. OK.

7
00:01:18,000 --> 00:01:26,600
All solid, all six ground starts are burned out, and we have ignited the air starts and jettisoned the ground start solid motors.

8
00:01:34,000 --> 00:01:41,800
Vehicle transients at solid motor jettison are nominal. Three air start motors picking up, all burning symmetrically.

9
00:01:42,000 --> 00:01:45,666
They've reached their peak chamber pressure, excuse me.

10
00:01:49,000 --> 00:01:55,933
Vehicle now at an altitude of 16 miles, downrange distance 36 miles and velocity of 3,400 miles an hour.

11
00:01:57,000 --> 00:02:00,066
Main engine and burners continue to burn well.
