00:00:06,680 --> 00:00:04,350
most prized pieces of oceanfront

00:00:09,620 --> 00:00:06,690
property and lit up like a four and a

4
00:00:11,959 --> 00:00:09,630
half million pound candle space shuttle

5
00:00:13,910 --> 00:00:11,969
Discovery is fully fueled and ready for

6
00:00:16,369 --> 00:00:13,920
its early morning liftoff from launch

7
00:00:20,929 --> 00:00:16,379
pad 39a here at Kennedy Space Center in

8
00:00:22,960 --> 00:00:20,939
Florida discoveries bright orange

9
00:00:25,460 --> 00:00:22,970
external tank is filled with more than

10
00:00:28,250 --> 00:00:25,470
500,000 gallons of liquid hydrogen and

11
00:00:30,500 --> 00:00:28,260
liquid oxygen the shuttles power

12
00:00:33,590 --> 00:00:30,510
producing fuel cells general-purpose

13
00:00:35,569 --> 00:00:33,600
computers and life-support systems are

14
00:00:39,500 --> 00:00:35,579
all activated and everything is working

15
00:00:41,780 --> 00:00:39,510
as expected about three and a half miles

16
00:00:43,369 --> 00:00:41,790
away from discovery launch controllers

17
00:00:45,770 --> 00:00:43,379
in kennedy's launch control center

18
00:00:47,479 --> 00:00:45,780
firing room for our overseeing all of

19
00:00:49,400 --> 00:00:47,489
the shuttle systems and verifying the

20
00:00:53,720 --> 00:00:49,410
step-by-step processes that will lead to

21
00:00:59,260 --> 00:00:53,730
an expected liftoff at 6 21 and 25

22
00:01:05,210 --> 00:01:02,090
Discovery's crew is awakened at 8pm

Easter Sunday ate breakfast at

24
00:01:10,130 --> 00:01:07,950
eight-thirty underwent standard medical

25
00:01:12,410 --> 00:01:10,140
checks at nine o'clock and has been

26
00:01:16,070 --> 00:01:12,420
making last-minute preparations for this

27
00:01:18,620 --> 00:01:16,080
morning's launch attempt this will be

28
00:01:21,830 --> 00:01:18,630
the 35th night launch and space shuttle

29
00:01:23,870 --> 00:01:21,840
program history and as the shuttle

30
00:01:25,999 --> 00:01:23,880
rockets to the Northeast it will make an

31
00:01:27,950 --> 00:01:26,009
early morning wake-up call to residents

32
00:01:30,620 --> 00:01:27,960
of the Space Coast as well as much of

33
00:01:34,429 --> 00:01:30,630
America's East Coast as it climbs and

34
00:01:38,780 --> 00:01:34,439
accelerates to 17,500 miles an hour in

35
00:01:40,190 --> 00:01:38,790
just eight and a half minutes right

36
00:01:42,050 --> 00:01:40,200
after the launch tower is cleared

37
00:01:44,569 --> 00:01:42,060
discovery will perform a roll maneuver

38
00:01:48,350 --> 00:01:44,579
pointing it precisely on the trajectory

39
00:01:51,469 --> 00:01:48,360
of 51.6 degrees to catch up to the

40
00:01:53,899 --> 00:01:51,479
International Space Station at the time

41
00:01:55,999 --> 00:01:53,909
of liftoff the station will be about 220

42
00:01:58,760 --> 00:01:56,009
miles over the Atlantic Ocean south west

43
00:02:02,780 --> 00:01:58,770
of Ireland but about 17 minutes before

44
00:02:04,870 --> 00:02:02,790
launch at 604 am the space station will

45
00:02:07,069 --> 00:02:04,880
pass over the kennedy space center

46
00:02:08,630 --> 00:02:07,079
providing an excellent sighting

47
00:02:11,660 --> 00:02:08,640
opportunity as it moves from the south

48
00:02:13,220 --> 00:02:11,670
south west to the east and it should be

49
00:02:17,000 --> 00:02:13,230
visible for about three minutes

50
00:02:18,559 --> 00:02:17,010
peeking out of 43 degree elevation so

51
00:02:20,270 --> 00:02:18,569
here inside the launch control center

52
00:02:22,399 --> 00:02:20,280
the countdown for Discovery's launch is

53
00:02:25,820 --> 00:02:22,409
continuing on schedule the launch window

54
00:02:27,380 --> 00:02:25,830
opens at six 16 and 25 seconds and are

55
00:02:31,089 --> 00:02:27,390
preferred and planned launch time is

56
00:02:33,830 --> 00:02:31,099
exactly five minutes later at six 2125

57
00:02:37,070 --> 00:02:33,840
the launch window for a flight day three

58
00:02:39,380 --> 00:02:37,080
rendezvous closes at six 26 and 25

59
00:02:41,900 --> 00:02:39,390
seconds and for a flight day for

60
00:02:45,470 --> 00:02:41,910
rendezvous three minutes later at six 29

61
00:02:46,880 --> 00:02:45,480
and 35 seconds NASA managers have

62
00:02:49,220 --> 00:02:46,890
determined that they would use the

63
00:02:53,089 --> 00:02:49,230
flight day for opportunity if it became

64
00:02:55,009 --> 00:02:53,099
necessary we're at t-minus three hours
