1
00:00:15,799 --> 00:00:13,520
skylab was the first test of our ability

2
00:00:17,540 --> 00:00:15,809
to endure weightlessness and astronauts

3
00:00:20,120 --> 00:00:17,550
found that they could effectively work

4
00:00:23,179 --> 00:00:20,130
exercise eat and sleep in their

5
00:00:25,070 --> 00:00:23,189
temporary home more recently the space

6
00:00:27,800 --> 00:00:25,080
shuttle has allowed us to fly into orbit

7
00:00:29,660 --> 00:00:27,810
conduct our business and return in

8
00:00:31,510 --> 00:00:29,670
addition to providing a laboratory for

9
00:00:33,740 --> 00:00:31,520
carrying out experiments in microgravity

10
00:00:35,930 --> 00:00:33,750
Arizona was also renovated us

11
00:00:39,010 --> 00:00:35,940
commercially and scientifically through

12
00:00:41,840 --> 00:00:39,020
the deployment and capture of satellites

13
00:00:44,360 --> 00:00:41,850
hello world the shuttle was designed

14
00:00:46,400 --> 00:00:44,370
with a larger goal in mind to transport

15
00:00:54,960 --> 00:00:46,410
astronauts and materials to a proposed

16
00:01:01,119 --> 00:00:58,479
in November of 1985 shuttle astronauts

17
00:01:03,160 --> 00:01:01,129
Jerry Ross and sherwin spring tested an

18
00:01:05,530 --> 00:01:03,170
assembly concept for construction of

19
00:01:09,490 --> 00:01:05,540
erectile structures in space more

20
00:01:11,650 --> 00:01:09,500
commonly known as access holes were

21
00:01:13,300 --> 00:01:11,660
linked together to make a frame similar

22
00:01:18,640 --> 00:01:13,310
to Romero will be used to build the

23
00:01:20,290 --> 00:01:18,650
space station in the early 1990s at the

24
00:01:22,540 --> 00:01:20,300
McDonnell Douglas underwater test

25
00:01:24,700 --> 00:01:22,550
facility astronauts can practice outer

26
00:01:27,969 --> 00:01:24,710
space construction in a neutral buoyancy

27
00:01:30,190 --> 00:01:27,979
tank here they assemble poles in 25

28
00:01:32,609 --> 00:01:30,200
meter cube at central service building

29
00:01:34,990 --> 00:01:32,619
blocks for the framework of the station

30
00:01:36,370 --> 00:01:35,000
sophisticated robot systems will assist

31
00:01:38,710 --> 00:01:36,380
in the building of the station and

32
00:01:41,310 --> 00:01:38,720
capture of satellites according to space

33
00:01:43,779 --> 00:01:41,320
station chief scientist dr. David black

34
00:01:46,690 --> 00:01:43,789
now one of the crucial capabilities and

35
00:01:48,730 --> 00:01:46,700
it's being provided by Canada is a major

36
00:01:51,639 --> 00:01:48,740
remote manipulator that will run around

37
00:01:53,650 --> 00:01:51,649
and on a trust like structure on tracks

38
00:01:55,480 --> 00:01:53,660
and be able to move all throughout the

39
00:01:57,069 --> 00:01:55,490
space station and the reason that's

40
00:02:00,520 --> 00:01:57,079
important is that we plan on using that

41
00:02:03,310 --> 00:02:00,530
robust very healthy arm to assemble the

42
00:02:04,810 --> 00:02:03,320
space station itself the OMB are the

43
00:02:07,240 --> 00:02:04,820
orbiting maneuvering vehicle is in

44
00:02:10,710 --> 00:02:07,250
effect a little space tug and its

45
00:02:13,090 --> 00:02:10,720
purpose is to go out attach itself to

46
00:02:15,610 --> 00:02:13,100
satellites which we want to bring back

47
00:02:17,050 --> 00:02:15,620
to the space station for repair hold

48
00:02:18,490 --> 00:02:17,060
them back into the vicinity of the space

49
00:02:20,440 --> 00:02:18,500
station then they can be put in the

50
00:02:23,710 --> 00:02:20,450
hangar or the garage where the

51
00:02:25,630 --> 00:02:23,720
astronauts can then work on it the new

52
00:02:28,300 --> 00:02:25,640
space station is designed to avoid the

53
00:02:30,699 --> 00:02:28,310
tremendous drag of solar arrays by

54
00:02:32,440 --> 00:02:30,709
incorporating solar dynamics large

55
00:02:34,600 --> 00:02:32,450
mirrors will reflect the sun's energy

56
00:02:38,690 --> 00:02:34,610
onto a fluid which becomes superheated

57
00:02:43,290 --> 00:02:41,430
roughly the size of a football field the

58
00:02:45,230 --> 00:02:43,300
space station will house modules from

59
00:02:47,670 --> 00:02:45,240
the United States Japan and Europe

60
00:02:51,440 --> 00:02:47,680
modules provide space for housing

61
00:02:54,000 --> 00:02:51,450
microgravity and life science research

62
00:02:56,040 --> 00:02:54,010
making a place to live that meets crew

63
00:02:58,320 --> 00:02:56,050
needs in an airless weightless

64
00:03:01,230 --> 00:02:58,330
environment is a primary importance in

65
00:03:03,930 --> 00:03:01,240
the space station design again dr. black

66
00:03:07,650 --> 00:03:03,940
we are trying to make the habitability

67
00:03:09,510 --> 00:03:07,660
part of the structure comfortable as

68
00:03:11,460 --> 00:03:09,520
much space as we possibly get so that

69
00:03:12,990 --> 00:03:11,470
the astronauts don't feel crime there

70
00:03:14,160 --> 00:03:13,000
will be windows in the facility so they

71
00:03:17,970 --> 00:03:14,170
can look out and it turns out that's

72
00:03:23,250 --> 00:03:20,940
NASA's Space Station a springboard for
