liftoff of the united launch alliance

00:00:22,790 --> 00:00:18,640
atlas v rocket with the stp-3 mission

14
00:00:26,470 --> 00:00:24,070
vehicle has cleared the tower and is

15
00:00:28,070 --> 00:00:26,480
beginning the pitchover program

16
00:00:29,910 --> 00:00:28,080
and the rd-180 is throttling down

17
00:00:32,229 --> 00:00:29,920
slightly as expected engine response

18
00:00:34,069 --> 00:00:32,239
looks good

19
00:00:36,549 --> 00:00:34,079
and passing 20 seconds into flight the

20
00:00:38,229 --> 00:00:36,559
pu system has gone to close loop control

21
00:00:40,630 --> 00:00:38,239

mach 1 atlas 5 is now supersonic

passing 45 seconds into flight the

26
00:01:08,310 --> 00:01:00,480
vehicle is now passing through max q

27
00:01:13,109 --> 00:01:10,390
and the rd-180 is throttling back up as

28
00:01:14,630 --> 00:01:13,119
expected engine response looks good

29
00:01:17,830 --> 00:01:14,640
passing one minute into flight the

30
00:01:20,070 --> 00:01:17,840
vehicle is now nine miles in altitude

00:01:30,149 --> 00:01:20,080
uh seven miles downrange traveling at

32
00:01:34,149 --> 00:01:31,910
and the rd-180 is throttling down again

33
00:01:45,590 --> 00:01:34,159
as expected engine response looks good

34
00:01:49,109 --> 00:01:47,270
and just past a minute and a minute and

35
00:01:51,270 --> 00:01:49,119
a half into flight we have burnout on

00:01:52,710 --> 00:01:51,280
all five srbs burnout pressure

37
00:01:54,950 --> 00:01:52,720
signatures are looking good and the

38
00:01:57,350 --> 00:01:54,960
rd180 is being throttled back up as

39
00:02:09,990 --> 00:01:57,360
expected following srb burnout

40
00:02:13,350 --> 00:02:11,510
and we have good indication of jettison

41
00:02:15,030 --> 00:02:13,360
of all five srbs and the vehicle has

42
00:02:18,070 --> 00:02:15,040
gone to closed loop q alpha limited
