00:00:31,580 --> 00:00:29,630
rockaway discovery discoveries roll

5
00:00:33,799 --> 00:00:31,590
maneuver is completed it is now in a

00:00:35,180 --> 00:00:33,809
heads down position on track parts

7
00:00:43,130 --> 00:00:35,190
flight to the International Space

8
00:00:48,740 --> 00:00:47,299
discovery flying 365 miles per hour one

00:00:50,869 --> 00:00:48,750
a half one and a half miles in altitude

Space Center discoveries engines are

12
00:00:57,590 --> 00:00:55,860
throttling down as the orbiter passes

13
00:01:14,610 --> 00:00:57,600
through the area of maximum pressure on

14
00:01:23,260 --> 00:01:19,660
discovery go at throttle up this country

15
00:01:26,560 --> 00:01:23,270
go and throw up three main engines on

16
00:01:28,030 --> 00:01:26,570
board are throttling back up now one

00:01:30,760 --> 00:01:28,040
minute 12 seconds into the flight

18
00:01:33,250 --> 00:01:30,770
discovery flying it 1800 miles per hour

19
00:01:34,930 --> 00:01:33,260
ten miles in altitude and eleven and a

00:01:49,359 --> 00:01:47,509
four and a half million pounds the total

24
00:01:53,100 --> 00:01:49,369
thrust at launch was six million four

25
00:01:55,749 --> 00:01:53,110
hundred and twenty-five thousand pounds

26
00:01:58,660 --> 00:01:55,759
all systems continue to function well

27
00:02:00,790 --> 00:01:58,670
three good main engines three good power

28
00:02:03,190 --> 00:02:00,800
generating fuel cells and three good

29
00:02:07,749 --> 00:02:03,200
auxiliary power units for the hydraulic

30
00:02:09,340 --> 00:02:07,759
system we will now stand by for burnout

31
00:02:11,979 --> 00:02:09,350
and separation of the solid rocket

32
00:02:14,590 --> 00:02:11,989
boosters combined the twin boosters

33
00:02:27,330 --> 00:02:14,600
provide 5.3 million pounds of thrust to
