space shuttle discovery the venerable

00:00:11,270 --> 00:00:08,880
veteran of america's human space flight

00:00:13,589 --> 00:00:11,280
fleet proudly resting atop launch pad

00:00:15,350 --> 00:00:13,599
39a here at nasa's kennedy space center

5
00:00:18,150 --> 00:00:15,360
in florida

6
00:00:22,550 --> 00:00:18,160
her wings outstretched and ready to soar

7
00:00:24,950 --> 00:00:22,560
into space for the 39th and final time

8
00:00:28,070 --> 00:00:24,960
and here we have the crew

9
00:00:30,070 --> 00:00:28,080
walking out of crew corners

10
00:00:31,990 --> 00:00:30,080
this is a very historical walkway it's

11
00:00:34,310 --> 00:00:32,000
the same path that uh the apollo

12
00:00:36,470 --> 00:00:34,320
astronauts took to go to the moon

13
00:00:39,590 --> 00:00:36,480
and over the last 30 years there's been

14
00:00:40,389 --> 00:00:39,600
a 133 odd shuttle crews that walked out

15
00:00:42,950 --> 00:00:40,399
here

16
00:00:45,510 --> 00:00:42,960
to catch this bus for the exciting ride

17
00:00:47,910 --> 00:00:45,520
out to the launch pad

18
00:00:49,510 --> 00:00:47,920
the crew will step out of the astro van

19
00:00:54,950 --> 00:00:49,520
and

20
00:00:57,430 --> 00:00:54,960
look up which is a little hard to do in

21
00:00:59,349 --> 00:00:57,440
the uh

22
00:01:00,470 --> 00:00:59,359
heavy suits that they have

23
00:01:02,950 --> 00:01:00,480
but uh

24
00:01:04,630 --> 00:01:02,960
you get an opportunity to stand there

25
00:01:07,270 --> 00:01:04,640
and see the shuttle from a very unique

26
00:01:09,030 --> 00:01:07,280
perspective uh

27
00:01:10,710 --> 00:01:09,040
the view itself is spectacular but your

28
00:01:12,390 --> 00:01:10,720
perspective is particularly unique

29
00:01:15,190 --> 00:01:12,400
because you know that it is the ride

30
00:01:18,149 --> 00:01:15,200
that's going to take you

31
00:01:21,830 --> 00:01:20,390
there you can see the crew having a

32
00:01:25,830 --> 00:01:21,840
group hug and

33
00:01:31,910 --> 00:01:25,840
a little quiet moment for themselves to

34
00:01:38,310 --> 00:01:34,149
wish each other well

35
00:01:43,270 --> 00:01:41,590
20 seconds the sound suppression water

36
00:01:45,510 --> 00:01:43,280
system

37
00:01:47,429 --> 00:01:45,520
has been activated protecting discovery

38
00:01:50,069 --> 00:01:47,439
and the launch pad from acoustical

39
00:01:52,710 --> 00:01:50,079
energy waves

40
00:01:55,749 --> 00:01:52,720
go for main engine start

41
00:01:56,709 --> 00:01:55,759
we have main engine start

42
00:01:57,990 --> 00:01:56,719
two

43
00:02:00,630 --> 00:01:58,000
one

44
00:02:03,590 --> 00:02:00,640
booster ignition and the final liftoff

45
00:02:05,670 --> 00:02:03,600
of discovery a tribute to the dedication

46
00:02:07,670 --> 00:02:05,680
hard work and pride of america's space

47
00:02:13,030 --> 00:02:07,680

mission control houston space shuttle

49
00:02:18,390 --> 00:02:16,560
now rolling over onto its back for a

50
00:02:20,309 --> 00:02:18,400
10-minute ride

51
00:02:43,430 --> 00:02:20,319
discovery now making one last reach for

52
00:02:46,229 --> 00:02:44,790
engines are now throttling down as the

53
00:02:47,990 --> 00:02:46,239
orbiter passes through the area of

54
00:03:01,190 --> 00:02:48,000
maximum pressure reducing the stress on

55
00:03:10,949 --> 00:03:03,350
discovery houston you are go at throttle

56
00:03:13,350 --> 00:03:11,990
well commander steve lindsay

57
00:03:15,110 --> 00:03:13,360
acknowledging the call from capcom

58
00:03:20,550 --> 00:03:15,120

59
00:03:23,750 --> 00:03:21,990
lindsay is joined on the flight deck by

steve bowen

63
00:03:37,670 --> 00:03:36,480
discovery's three main engines are

64
00:03:39,509 --> 00:03:37,680
burning fuel at a rate that would drain

65
00:03:41,430 --> 00:03:39,519
an average swimming pool in about 25

66
00:03:42,789 --> 00:03:41,440
seconds

67
00:03:44,470 --> 00:03:42,799
the engines combined with the solid

68
00:03:47,509 --> 00:03:44,480
rocket boosters produce more than seven

69
00:03:49,190 --> 00:03:47,519
million pounds of thrust

70
00:03:50,550 --> 00:03:49,200
one minute 50 seconds into the flight

71
00:03:52,550 --> 00:03:50,560
we're standing by for separation of the

72
00:03:55,509 --> 00:03:52,560
twin solid rocket boosters discovery now

73
00:03:57,750 --> 00:03:55,519
traveling 2695 miles an hour its

74
00:04:12,869 --> 00:03:57,760
altitude 24 miles downrange from the

75
00:04:16,310 --> 00:04:14,789
booster separation confirmed discovery's

76
00:04:18,150 --> 00:04:16,320
guidance is now converging as the

77
00:04:23,670 --> 00:04:18,160
shuttle's onboard computers fine-tune

78
00:04:27,670 --> 00:04:25,430
