00:00:25,670 --> 00:00:22,950
and we have liftoff of tdrs m on the

atlas v rocket from space launch complex

nominal supersonic speed at one minute

25
00:01:23,510 --> 00:01:21,590
passing one minute into play

26
00:01:25,270 --> 00:01:23,520
the vehicle is now three miles in

27
00:01:32,950 --> 00:01:25,280
altitude

28
00:01:36,550 --> 00:01:35,109
standing by for max q and now passing

one minute

00:01:48,389 --> 00:01:39,200

00:01:54,469 --> 00:01:52,560
passing through max q maximum dynamic

pressure

34
00:01:58,149 --> 00:01:56,240
this is the point when mechanical stress

35
00:01:59,990 --> 00:01:58,159
on the rocket reaches its peak because

36
00:02:01,990 --> 00:02:00,000
of the rocket's velocity and resistance

37
00:02:04,950 --> 00:02:02,000
created by the rd-180 is throttled down

38
00:02:07,109 --> 00:02:04,960
to 95 thrust as expected engine response

39
00:02:08,630 --> 00:02:07,119
looks good this engine thrust profile

40
00:02:16,710 --> 00:02:08,640
will continue until the vehicle reaches

41
00:02:19,750 --> 00:02:18,070
about two minutes into the flight of

42
00:02:21,110 --> 00:02:19,760
that passing two minutes into flight

43
00:02:23,030 --> 00:02:21,120
approximately two minutes remaining in

44
00:02:25,030 --> 00:02:23,040

booster engine cut off slated for four

49
00:02:38,949 --> 00:02:37,360
minutes two seconds after launch atlas

50
00:02:40,630 --> 00:02:38,959
five rocket now weighs just one half of

51
00:02:42,710 --> 00:02:40,640
what it did at launch burning propellant

52
00:02:44,630 --> 00:02:42,720
at a rate of almost 2 600 pounds per

53
00:02:46,150 --> 00:02:44,640
second

54
00:02:48,070 --> 00:02:46,160

guidance

56
00:02:59,830 --> 00:02:50,000
now passing two minutes 30 seconds into

00:03:03,430 --> 00:03:01,750
and rcs pyro valve has been fired

58
00:03:05,910 --> 00:03:03,440
centaur reaction control system is now

59
00:03:08,710 --> 00:03:05,920
pressurizing the flight levels

60
00:03:10,630 --> 00:03:08,720
atlas 5 is now 30 miles in altitude 43

miles downrange distance traveling at 4

62
00:03:20,470 --> 00:03:19,110

limit

73
00:04:03,270 --> 00:04:01,360
and we've begun boost phase chill down

74
00:04:09,670 --> 00:04:03,280
less than 30 seconds away from booster

second stage will separate from the

79
00:04:26,230 --> 00:04:22,790
and we have beco booster engine cutoff

80
00:04:31,909 --> 00:04:27,830
ten seconds after separation good

00:04:37,430 --> 00:04:34,390
the central single rlc engine ignites

82
00:04:43,189 --> 00:04:39,270
we have ignition and full thrust on the

83
00:04:45,110 --> 00:04:43,199
rl10 the rl10 produces 22 900 pounds of

84

thrust and burns for just under eight

85
00:04:47,590 --> 00:04:46,240
minutes

86
00:04:49,270 --> 00:04:47,600

88
00:04:52,310 --> 00:04:50,880
this is the first of two planned burns

89
00:04:53,990 --> 00:04:52,320
for today's mission this first burn

90
00:04:58,710 --> 00:04:54,000
