00:00:12,370 --> 00:00:22,070
one . . . drop. And Pegasus is away, standing by for ignition.

4
00:00:22,070 --> 00:00:25,960
George Diller/Launch Commentator: And we have Stage 1 ignition.

5
00:00:25,960 --> 00:00:34,300
Ignition of the Pegasus rocket with NuSTAR for an understanding of the ultimate destinies of our stars and galaxies.

6
00:00:34,300 --> 00:00:36,550
Ascent Commentator: Fin actuator system operating nominally.

7
00:00:36,550 --> 00:00:41,430
Fins following commands and controlling the flight of the vehicle.

8
00:00:41,430 --> 00:00:48,200
Power bus is strong, PDUs enabled. Vehicle flight path is nominal, flying the normal trajectory.

9
00:00:48,200 --> 00:00:51,000
George Diller/Launch Commentator: This is Steve Hollo, our launch systems engineer.

10
00:00:51,000 --> 00:01:02,220
Ascent Commentator: Ignition time was 16:00:42. Attitude remains nominal. Past max Q.

11
00:01:02,220 --> 00:01:12,160
Power bus is strong. Nominal voltage and currents on all buses. Aft power bus strong.

12
00:01:12,160 --> 00:01:19,740
Passing 100,000 feet. Approximately 10 seconds to Stage 1 burnout.

13
00:01:19,740 --> 00:01:22,520
Launch Controller: 10 seconds to Stage 1 burnout.

14
00:01:22,520 --> 00:01:26,720
Ascent Commentator: Vehicle IIP is through the narrowest part of the corridor. Stage 1 burnout.

15
00:01:26,720 --> 00:01:28,480
Launch Controller: Stage 1 burnout.

16
00:01:28,480 --> 00:01:36,430
Ascent Commentator: Approximately 15 seconds to Stage 1 separation, Stage 2 ignition.

17
00:01:36,430 --> 00:01:47,840
Vehicle power buses remain strong. Stage 2 TVC on and nominal. Stage 1 sep.

18
00:01:47,840 --> 00:01:48,770
Launch Controller: We have Stage 1 sep.
