1
00:00:07,590 --> 00:00:04,470
from the first grainy pictures of earth

2
00:00:10,709 --> 00:00:07,600
to today's high definition imagery

3
00:00:15,190 --> 00:00:10,719
nasa tv has provided the world with a

4
00:00:18,150 --> 00:00:16,470
i think that's one of the best things we

5
00:00:20,310 --> 00:00:18,160
ever we ever did in the space program

6
00:00:22,390 --> 00:00:20,320
one of the best decisions ever made

7
00:00:24,310 --> 00:00:22,400
with regard to the space program was uh

8
00:00:32,870 --> 00:00:24,320
to share that with the world

9
00:00:37,670 --> 00:00:35,670
this kind of footage is a major

10
00:00:39,510 --> 00:00:37,680
wonderful major accomplishment

11
00:00:41,990 --> 00:00:39,520
and for people to be able to see this i

12
00:00:44,389 --> 00:00:42,000
think it's just absolutely exhilarating

13
00:00:46,869 --> 00:00:44,399
not a tv channel or network

14
00:00:49,029 --> 00:00:46,879
nasa television is a service that helps

15
00:00:51,270 --> 00:00:49,039
assure the mission success of the space

16
00:00:53,110 --> 00:00:51,280
shuttle and international space station

17
00:00:55,670 --> 00:00:53,120
programs and

18
00:00:58,310 --> 00:00:55,680
safety of their astronauts one

19
00:01:00,470 --> 00:00:58,320
and liftoff of space shuttle discovery

20
00:01:03,830 --> 00:01:00,480
beginning america's new journey to the

21
00:01:06,429 --> 00:01:03,840
moon mars and beyond and the vehicle has

22
00:01:07,990 --> 00:01:06,439
cleared the tower such as on

23
00:01:09,990 --> 00:01:08,000
sts-114

24
00:01:12,469 --> 00:01:10,000
the space shuttle's return to flight

25
00:01:14,149 --> 00:01:12,479
mission after the columbia disaster just

26
00:01:16,230 --> 00:01:14,159
you know we have a great downlink of

27
00:01:17,510 --> 00:01:16,240
steve's wps right now we're really

28
00:01:20,230 --> 00:01:17,520
enjoying the view

29
00:01:23,030 --> 00:01:20,240
the live video provided by nasa tv's

30
00:01:24,789 --> 00:01:23,040
robust communications infrastructure

31
00:01:27,429 --> 00:01:24,799
helped ground controllers guide

32
00:01:29,670 --> 00:01:27,439
astronaut steve robinson as he plucked a

33
00:01:31,190 --> 00:01:29,680
protruding gap filler from discovery's

34
00:01:33,030 --> 00:01:31,200
underbelly

35
00:01:36,550 --> 00:01:33,040
okay i'm grabbing it and i'm pulling

36
00:01:41,109 --> 00:01:39,190
beautiful nicely downstairs

37
00:01:43,350 --> 00:01:41,119
on sts-120

38
00:01:46,469 --> 00:01:43,360
ground-based engineers could watch on

39
00:01:49,030 --> 00:01:46,479
nasa television as astronauts dan tawney

40
00:01:52,950 --> 00:01:49,040
and scott parazynski worked outside the

41
00:01:55,350 --> 00:01:52,960
iss to successfully free a snagged solar

42
00:01:57,350 --> 00:01:55,360
array we've got deployed discretes to

43
00:01:58,870 --> 00:01:57,360
deploy the streets

44
00:02:00,069 --> 00:01:58,880
all right

45
00:02:02,389 --> 00:02:00,079
great news

46
00:02:04,709 --> 00:02:02,399
beautiful what an accomplishment

47
00:02:06,550 --> 00:02:04,719
nice teamwork and on the final space

48
00:02:09,669 --> 00:02:06,560
shuttle mission to service the hubble

49
00:02:12,150 --> 00:02:09,679
space telescope mission control could

50
00:02:16,229 --> 00:02:12,160
see the problem encountered by astronaut

51
00:02:20,630 --> 00:02:18,949
but i think it's the gasket

52
00:02:21,430 --> 00:02:20,640
i think the gasket is kind of keeping it

53
00:02:26,229 --> 00:02:21,440
off

54
00:02:28,949 --> 00:02:26,239
at a picture we think one option would

55
00:02:30,949 --> 00:02:28,959
be to take it off completely and flip it

56
00:02:33,430 --> 00:02:30,959
over and try to roll that edge of the

57
00:02:36,309 --> 00:02:33,440
gasket of course it wasn't always this

58
00:02:38,390 --> 00:02:36,319
is such a device as the lunar tv camera

59
00:02:40,070 --> 00:02:38,400
does one really exist

60
00:02:42,470 --> 00:02:40,080
well judge for yourself

61
00:02:45,030 --> 00:02:42,480
on my right is a monitor in which the

62
00:02:46,869 --> 00:02:45,040
signal from the actual lunar camera is

63
00:02:50,309 --> 00:02:46,879
being received

64
00:02:52,470 --> 00:02:50,319
no redundancy no second camera so it was

65
00:02:54,630 --> 00:02:52,480
going to be one camera on the moon with

66
00:02:55,830 --> 00:02:54,640
one little wire going back

67
00:02:57,270 --> 00:02:55,840
and that was it

68
00:02:59,030 --> 00:02:57,280
honeystop got a converter they would

69
00:03:00,949 --> 00:02:59,040
convert send to signal sydney parks

70
00:03:02,710 --> 00:03:00,959
didn't have a converter they would send

71
00:03:04,149 --> 00:03:02,720
what's called the sliscan tv down to

72
00:03:05,830 --> 00:03:04,159
sydney where we had our guys with the

73
00:03:07,910 --> 00:03:05,840
converter and then they would select the

74
00:03:09,830 --> 00:03:07,920
best source and send it out to nlsat to

75
00:03:11,750 --> 00:03:09,840
come to california to come to houston

76
00:03:13,830 --> 00:03:11,760
and it only took one guy with one patch

77
00:03:16,229 --> 00:03:13,840
to kill this whole event

78
00:03:18,869 --> 00:03:16,239
richard nafsker was the one nasa

79
00:03:21,589 --> 00:03:18,879
engineer most responsible for getting

80
00:03:24,309 --> 00:03:21,599
live pictures back from the moon on july

81
00:03:26,789 --> 00:03:24,319
20th 1969.

82
00:03:28,229 --> 00:03:26,799
once we landed safely the only thing

83
00:03:32,710 --> 00:03:28,239
that counted was

84
00:03:37,509 --> 00:03:35,190
the tv better worker else and if it

85
00:03:39,270 --> 00:03:37,519
doesn't they really will know who i am

86
00:03:50,710 --> 00:03:39,280
because i'll be the man who didn't bring

87
00:03:55,830 --> 00:03:53,429
as nasa tv has striven for mission

88
00:03:58,390 --> 00:03:55,840
success it has also produced some

89
00:04:00,550 --> 00:03:58,400
extraordinarily compelling television

90
00:04:13,110 --> 00:04:00,560
while keeping the world informed of and

91
00:04:18,469 --> 00:04:15,910
what was once a single analog part-time

92
00:04:20,870 --> 00:04:18,479
five-day-a-week offering has matured

93
00:04:23,510 --> 00:04:20,880
into a four-channel digital array

94
00:04:25,990 --> 00:04:23,520
including an hd outlet to fulfill the

95
00:04:28,710 --> 00:04:26,000
secondary yet important role of

96
00:04:30,469 --> 00:04:28,720
informing the public of nasa's mission

97
00:04:32,710 --> 00:04:30,479

events

100
00:04:37,270 --> 00:04:36,080

101

interviews

102
00:04:41,590 --> 00:04:38,960
