00:00:06,019 --> 00:00:04,039
we are transferring to orbiter internal

2
00:00:08,410 --> 00:00:06,029
power at this time discovery is now

3
00:00:11,000 --> 00:00:08,420
running off its three onboard fuel cells

4
00:00:22,640 --> 00:00:11,010
coming up on a go for all the sequence

5
00:00:24,740 --> 00:00:22,650
start go for autosequence apart and we

6
00:00:26,750 --> 00:00:24,750
have a go for autosequence start scart

7
00:00:29,210 --> 00:00:26,760
discoveries onboard computers have

8
00:00:33,170 --> 00:00:29,220
primary control of all the vehicles

9
00:00:48,940 --> 00:00:33,180
critical functions t-minus 17 seconds

10
00:00:52,880 --> 00:00:48,950
and counting 15 12 11 10 9 8 7 6 start

00:00:55,459 --> 00:00:52,890
21 booster ignition and liftoff of the

12
00:00:57,260 --> 00:00:55,469
space shuttle Discovery returning to the

13
00:01:01,030 --> 00:00:57,270
space station paving the way for future

14
00:01:01,040 --> 00:01:09,930
the government program

15
00:01:20,310 --> 00:01:11,360
which is roll

16
00:01:20,320 --> 00:01:23,480
new discoveries

17
00:01:23,490 --> 00:01:28,200
start to discover his mission

18
00:01:31,980 --> 00:01:30,390
discovery's 3 liquid fuel main engines

19
00:01:33,690 --> 00:01:31,990
now throttling back to sixty-seven

20
00:01:35,010 --> 00:01:33,700
percent of rated performance reducing

21
00:01:37,920 --> 00:01:35,020
the stress on the shuttle as it breaks

22
00:01:39,450 --> 00:01:37,930
through the sound barrier discovery

23
00:01:41,249 --> 00:01:39,460
already three and a half miles in

24
00:01:44,420 --> 00:01:41,259
altitude one and a half miles downrange

25
00:01:49,889 --> 00:01:44,430
traveling almost 750 miles an hour

26
00:01:51,870 --> 00:01:49,899
everything looking good on the bird 57

27
00:01:57,270 --> 00:01:51,880
seconds into the flight engines

28
00:02:06,030 --> 00:01:59,370
standing by for the throttle up call

29
00:02:09,510 --> 00:02:06,040
from Capcom Steve Frank every you can go

30
00:02:12,480 --> 00:02:09,520
and throttle up the proprietor going

31
00:02:14,100 --> 00:02:12,490
problem here at have only the throttle

32
00:02:16,320 --> 00:02:14,110
up call acknowledged by Commander Steve

33
00:02:24,059 --> 00:02:16,330
Lindsey every youth in its expected data

34
00:02:25,740 --> 00:02:24,069
hits it'll clear shortly Lindsay joined
