1
00:00:44,189 --> 00:00:42,240
using balloons and rockets astronomers

2
00:00:46,500 --> 00:00:44,199
have successfully launched telescopes

3
00:00:49,350 --> 00:00:46,510
into earth orbit above the distorting

4
00:00:51,840 --> 00:00:49,360
effects of the atmosphere to explore

5
00:00:55,110 --> 00:00:51,850
deep space nASA has had great success

6
00:00:57,360 --> 00:00:55,120
with robotic probes like Voyager that

7
00:01:00,329 --> 00:00:57,370
have observed and sent back images of

8
00:01:02,729 --> 00:01:00,339
our solar system NASA and its partner

9
00:01:04,979 --> 00:01:02,739
the European Space Agency are now on the

10
00:01:07,460 --> 00:01:04,989
verge of launching a huge optical

11
00:01:11,279 --> 00:01:07,470
Observatory into orbit around the earth

12
00:01:13,190 --> 00:01:11,289
Hubble Space Telescope will see objects

13
00:01:16,350 --> 00:01:13,200
even near the edge of the known universe

14
00:01:19,649 --> 00:01:16,360
with ten times finer detailed and

15
00:01:21,719 --> 00:01:19,659
possible from the ground at the heart of

16
00:01:24,990 --> 00:01:21,729
the observatory is an eight-foot mirror

17
00:01:27,270 --> 00:01:25,000
grounded near perfection when pointed at

18
00:01:30,840 --> 00:01:27,280
an object the mirror collects light and

19
00:01:33,149 --> 00:01:30,850
sends it to six instruments various

20
00:01:34,980 --> 00:01:33,159
satellites and ground stations relay the

21
00:01:37,200 --> 00:01:34,990
instruments information to the Space

22
00:01:40,380 --> 00:01:37,210
Telescope Science Institute in Baltimore

23
00:01:42,359 --> 00:01:40,390
Maryland viewing screens will allow

24
00:01:44,969 --> 00:01:42,369
scientists to make real-time

25
00:01:47,039 --> 00:01:44,979
observations at the same time a

26
00:01:49,980 --> 00:01:47,049
tremendous amount of data will be

27
00:01:51,630 --> 00:01:49,990
generated according to dr. Eric JSON

28
00:01:53,870 --> 00:01:51,640
we're talking about a huge amount of

29
00:01:55,980 --> 00:01:53,880
information in fact we colloquially

30
00:01:57,990 --> 00:01:55,990
refer to this as drinking from a

31
00:02:00,480 --> 00:01:58,000
firehose in order to help astronomers

32
00:02:03,779 --> 00:02:00,490
plan observations the Space Telescope

33
00:02:06,630 --> 00:02:03,789
Institute has the largest star catalogue

34
00:02:10,770 --> 00:02:06,640
in the world containing 19 million

35
00:02:13,349 --> 00:02:10,780
celestial objects the catalog was made

36
00:02:16,319 --> 00:02:13,359
by scanning over 1,400 photographic

37
00:02:19,380 --> 00:02:16,329
plates of the entire sky the plates are

38
00:02:21,720 --> 00:02:19,390
also stored in a giant database so

39
00:02:24,449 --> 00:02:21,730
astronomers can call up a region like

40
00:02:28,110 --> 00:02:24,459
the Andromeda galaxy and manipulate the

41
00:02:33,420 --> 00:02:31,199
in our lifetime Space Telescope should

42
00:02:37,589 --> 00:02:33,430
match the discoveries made since the

43
00:02:40,350 --> 00:02:37,599
beginning of astronomy we hope to see in

44
00:02:42,570 --> 00:02:40,360
the words of galileo galilei wondrous

45
00:02:43,740 --> 00:02:42,580
things those were the words that he used

46
00:02:46,979 --> 00:02:43,750
in 1609

47
00:02:50,009 --> 00:02:46,989
we want to see star systems we'll want

48
00:02:51,690 --> 00:02:50,019
to see images of the planets but in

49
00:02:54,270 --> 00:02:51,700
particular space dollars will be

50
00:02:57,030 --> 00:02:54,280
designed to look out into deep space to

51
00:02:58,740 --> 00:02:57,040
study deep space astrophysics to arrive

52
00:03:17,480 --> 00:02:58,750
to a realm that we've not yet been able

53
00:03:24,120 --> 00:03:21,180
in 1990 shuttle discovery launched

54
00:03:27,479 --> 00:03:24,130
NASA's Hubble Space Telescope the most

55
00:03:30,860 --> 00:03:27,489
powerful Observatory ever built able to

56
00:03:33,540 --> 00:03:30,870
image detail up to 15 billion miles away

57
00:03:44,729 --> 00:03:33,550
Hubble has provided astronomers with a

58
00:03:47,070 --> 00:03:44,739
clearer window to our universe soon

59
00:03:49,740 --> 00:03:47,080
after Hubble was deployed scientists

60
00:03:54,120 --> 00:03:49,750
discovered an aberration in the 94 inch

61
00:03:56,190 --> 00:03:54,130
primary mirror even so the huge space

62
00:03:58,430 --> 00:03:56,200
porn telescope has been returning a

63
00:04:01,290 --> 00:03:58,440
steady stream of new information

64
00:04:04,890 --> 00:04:01,300
particularly with the aid of computer

65
00:04:07,440 --> 00:04:04,900
enhancement similar processing has been

66
00:04:11,300 --> 00:04:07,450
used on data from other spacecraft like

67
00:04:13,830 --> 00:04:11,310
Voyager which traveled past the planets

68
00:04:18,479 --> 00:04:13,840
enhancement now brings up more detail

69
00:04:20,810 --> 00:04:18,489
for Hubble scientists this is the

70
00:04:24,540 --> 00:04:20,820
telescope's original image of a galaxy

71
00:04:29,430 --> 00:04:24,550
52 million light-years from Earth as it

72
00:04:32,130 --> 00:04:29,440
is cleaned up to its final version here

73
00:04:36,120 --> 00:04:32,140
light pulses in a straight line between

74
00:04:38,640 --> 00:04:36,130
Earth and a distant quasar years ago

75
00:04:41,490 --> 00:04:38,650
Albert Einstein suggested that if a

76
00:04:44,159 --> 00:04:41,500
uniform object crossed the path light

77
00:04:46,980 --> 00:04:44,169
would bend into a ring but if the object

78
00:04:50,250 --> 00:04:46,990
were not uniform the ring would break up

79
00:04:53,640 --> 00:04:50,260
into four patches known as the Einstein

80
00:04:56,980 --> 00:04:53,650
cross Hubble's imagery confirmed this

81
00:05:02,080 --> 00:04:56,990
part of Einstein's theory of relativity

82
00:05:05,560 --> 00:05:02,090
a bull also showed scientists a

83
00:05:08,140 --> 00:05:05,570
celestial X marking the exact spot of a

84
00:05:13,300 --> 00:05:08,150
black hole with the possible mass of 1

85
00:05:15,040 --> 00:05:13,310
million of our Suns astronauts are

86
00:05:17,140 --> 00:05:15,050
already training to fix the Hubble

87
00:05:20,980 --> 00:05:17,150
mirror problem during a shuttle service

88
00:05:23,350 --> 00:05:20,990
call scheduled for late 1993 by

89
00:05:25,630 --> 00:05:23,360
substituting a special component in the

90
00:05:29,380 --> 00:05:25,640
telescope the aberration will be

91
00:05:31,540 --> 00:05:29,390
repaired called co-star this corrective

92
00:05:34,390 --> 00:05:31,550
optics package contains a series of

93
00:05:36,970 --> 00:05:34,400
mirrors that work like contact lenses to

94
00:05:41,920 --> 00:05:36,980
restore Hubble close to its full imaging

95
00:05:44,350 --> 00:05:41,930
potential in a clean room at NASA's

96
00:05:46,660 --> 00:05:44,360
Goddard Space Flight Center technicians

97
00:05:49,180 --> 00:05:46,670
also practice removing the spacecraft

98
00:05:57,160 --> 00:05:49,190
star tracker which helps point the

99
00:06:00,190 --> 00:05:57,170
telescope in the meantime I will

100
00:06:06,360 --> 00:06:00,200
continue to send back fine detail of the

101
00:06:10,960 --> 00:06:06,370
planets faraway galaxies black hole and

102
00:13:55,170 --> 00:06:10,970
distant stars rewriting the textbooks on

103
00:13:55,180 --> 00:13:59,050
yeah

104
00:14:04,340 --> 00:14:02,629
the science team knew that the best from

105
00:14:10,900 --> 00:14:04,350
the newly restored hubble space

106
00:14:17,480 --> 00:14:14,180
the purpose of today's press conference

107
00:14:19,930 --> 00:14:17,490
is to present and explain the first

108
00:14:23,120 --> 00:14:19,940
images from the hubble space telescope

109
00:14:27,139 --> 00:14:23,130
and i'm happy to announce today that

110
00:14:28,670 --> 00:14:27,149
after its launch now in 1990 some of its

111
00:14:32,780 --> 00:14:28,680
earlier disappointments

112
00:14:34,460 --> 00:14:32,790
the trouble with hubble is over it's

113
00:14:35,389 --> 00:14:34,470
often said that a picture is worth a

114
00:14:38,269 --> 00:14:35,399
thousand words

115
00:14:40,670 --> 00:14:38,279
in fact these corrected images are as

116
00:14:52,810 --> 00:14:40,680
perfect as engineering can achieve and

117
00:14:59,720 --> 00:14:56,480
for NASA at the beginning it had been

118
00:15:03,320 --> 00:14:59,730
tough to be the first then tougher still

119
00:15:16,890 --> 00:15:03,330
to stay at the front and now toughest of

120
00:15:20,940 --> 00:15:19,769
we appreciate your frankness ambling for

121
00:15:24,810 --> 00:15:20,950
the planning ship it's nice to know

122
00:15:28,040 --> 00:15:24,820
we're really working on yeah better

123
00:15:30,079 --> 00:15:28,050
educated or four-door

124
00:15:31,550 --> 00:15:30,089
our pleasure I've never seen the

125
00:15:33,680 --> 00:15:31,560
teamwork I've seen in this program

126
00:15:35,260 --> 00:15:33,690
people have pulled together from all the

127
00:15:39,199 --> 00:15:35,270
Centers Johnson at Kennedy Space Center

128
00:15:42,829 --> 00:15:39,209
Goddard headquarters contractors because

129
00:15:44,540 --> 00:15:42,839
I think deep down people realize because

130
00:15:48,410 --> 00:15:44,550
of what what's happened this program is

131
00:15:55,050 --> 00:15:52,500
to fix a telescope already in space the

132
00:15:57,210 --> 00:15:55,060
team had to diagnose the optics problem

133
00:15:59,760 --> 00:15:57,220
from the flawed images then build

134
00:16:02,760 --> 00:15:59,770
replicas of the telescope to develop

135
00:16:06,540 --> 00:16:02,770
test and retest the corrective optics

136
00:16:08,550 --> 00:16:06,550
and replacement hardware it was really

137
00:16:11,010 --> 00:16:08,560
exciting to see all the work that I had

138
00:16:13,140 --> 00:16:11,020
been manifested in in the tests because

139
00:16:15,720 --> 00:16:13,150
I spent you know two years preparing to

140
00:16:17,880 --> 00:16:15,730
actually test the co-star in the system

141
00:16:20,340 --> 00:16:17,890
functional and to have it all work

142
00:16:24,270 --> 00:16:20,350
quickly unplanned was really wonderful

143
00:16:26,490 --> 00:16:24,280
had to build mock-ups of every part of

144
00:16:30,450 --> 00:16:26,500
this of the servicing mission including

145
00:16:32,580 --> 00:16:30,460
the science instruments and complete

146
00:16:34,350 --> 00:16:32,590
mock-ups of the equipment going into the

147
00:16:36,600 --> 00:16:34,360
cargo bay of the shuttle what we're

148
00:16:39,270 --> 00:16:36,610
doing now is verifying that the camera

149
00:16:41,550 --> 00:16:39,280
is going to play properly with the rest

150
00:16:45,390 --> 00:16:41,560
of HST that it's going to fit into HST

151
00:16:47,670 --> 00:16:45,400
and that it's also going to be commanded

152
00:16:49,530 --> 00:16:47,680
properly by the ground system and talk

153
00:16:53,610 --> 00:16:49,540
to the computers onboard the HST

154
00:16:56,750 --> 00:16:53,620
properly to prepare the astronauts and

155
00:17:00,390 --> 00:16:56,760
servicing teams planned modified and

156
00:17:05,159 --> 00:17:00,400
endlessly practiced each task using a

157
00:17:10,749 --> 00:17:07,480
every time we set out to think through a

158
00:17:13,029 --> 00:17:10,759
task during every step along the way we

159
00:17:14,499 --> 00:17:13,039
go well what if that doesn't work what

160
00:17:16,509 --> 00:17:14,509
if this happens what if that happened

161
00:17:19,539 --> 00:17:16,519
and for each one of those what ifs we

162
00:17:22,470 --> 00:17:19,549
need to have a plan before the actual

163
00:17:25,870 --> 00:17:22,480
spacewalks astronaut story Musgrave

164
00:17:27,819 --> 00:17:25,880
predicted what they would face for every

165
00:17:30,190 --> 00:17:27,829
sub task I've looked at the things which

166
00:17:33,070 --> 00:17:30,200
are the most delicate and required the

167
00:17:36,399 --> 00:17:33,080
most really critical care the rate

168
00:17:38,680 --> 00:17:36,409
sensing units a place in name on and

169
00:17:44,919 --> 00:17:38,690
they have very narrow tolerance placing

170
00:17:47,390 --> 00:17:44,929
those on the tooth pins and then the

171
00:17:53,180 --> 00:17:47,400
solar rays I think it is making you like

172
00:17:55,970 --> 00:17:53,190
Snickers wide field planetary theory

173
00:17:58,580 --> 00:17:55,980
it's taken the mirror off in a very and

174
00:18:00,590 --> 00:17:58,590
very careful way and then protected and

175
00:18:07,010 --> 00:18:00,600
that optics which is right out there in

176
00:18:09,830 --> 00:18:07,020
front of your face the coasts are as big

177
00:18:21,410 --> 00:18:09,840
as a telephone booth very squared it's

178
00:18:24,080 --> 00:18:21,420
gotta go into the Ray that's exactly all

179
00:18:26,900 --> 00:18:24,090
the careful planning really paid off

180
00:18:29,240 --> 00:18:26,910
during the mission the crew and ground

181
00:18:32,090 --> 00:18:29,250
team even had prepared for surprises

182
00:18:34,940 --> 00:18:32,100
when a broken solar array wouldn't roll

183
00:18:42,450 --> 00:18:34,950
up for storage Kathy Thornton jettison

184
00:19:03,280 --> 00:18:46,080
it was caught like a sail on the wind of

185
00:19:10,610 --> 00:19:07,180
the mission sharpened Hubble's sight and

186
00:19:17,120 --> 00:19:14,510
we're actually building up our abilities

187
00:19:21,279 --> 00:19:17,130
to work in space we're laying the

188
00:19:23,259 --> 00:19:21,289
groundwork for the future

189
00:19:25,240 --> 00:19:23,269
the Hubble is our eyes that's how we're

190
00:19:26,560 --> 00:19:25,250
going to see back to the beginning of

191
00:19:28,330 --> 00:19:26,570
the universe that's how we tell what's

192
00:22:01,470 --> 00:19:28,340
happened to us in the past and where our

193
00:22:05,560 --> 00:22:04,180
so in some sense when we look at an

194
00:22:25,440 --> 00:22:05,570
object like this we're looking at the

195
00:25:01,730 --> 00:22:27,629
and the same fear well it's possible at

196
00:25:11,100 --> 00:25:09,180
moving material out there yeah and the

197
00:25:15,210 --> 00:25:11,110
same day well it's possibly the coldest

198
00:25:18,120 --> 00:25:15,220
actual was produced by a yeah in fact

199
00:25:21,650 --> 00:25:18,130
you could have particular future

200
00:25:24,770 --> 00:25:21,660
producing us in the structure

201
00:25:40,070 --> 00:25:24,780
that item look at those little tiny

202
00:25:42,230 --> 00:25:40,080
knots that's because this represents the

203
00:25:46,280 --> 00:25:42,240
last stage in the evolution of ordinary

204
00:25:49,400 --> 00:25:46,290
stars a star like our own like our own

205
00:25:52,250 --> 00:25:49,410
Sun is going to go through an episode of

206
00:25:53,030 --> 00:25:52,260
this sort in maybe 5 6 billion years

207
00:25:55,340 --> 00:25:53,040
from now

208
00:25:56,750 --> 00:25:55,350
so in some sense when we look at an

209
00:26:06,290 --> 00:25:56,760
object like this we're looking at the

210
00:26:08,690 --> 00:26:06,300
future of our own solar system if this

211
00:26:12,110 --> 00:26:08,700
star did have planets they would have

212
00:26:21,950 --> 00:26:12,120
been vaporized early in the stages of

213
00:26:24,710 --> 00:26:21,960
ejection they're not there anymore it

214
00:26:27,080 --> 00:26:24,720
was clearly the best image of planetary

215
00:26:29,050 --> 00:26:27,090
that I have certainly ever been involved

216
00:26:33,500 --> 00:26:29,060
with and that I've really ever seen and

217
00:26:35,480 --> 00:26:33,510
I remember stopping on the way home from

218
00:26:37,640 --> 00:26:35,490
looking at this and saying we've got to

219
00:26:40,220 --> 00:26:37,650
get a bottle of champagne and and have a

220
00:26:47,950 --> 00:26:40,230
toast because this is a spectacular

221
00:26:52,060 --> 00:26:49,900
I think it's beautiful for the same

222
00:27:03,060 --> 00:26:52,070
reason that it's interesting which is

223
00:27:06,610 --> 00:27:03,070
all the symmetry I think that this is

224
00:27:08,680 --> 00:27:06,620
probably the most exciting image of a

225
00:27:11,170 --> 00:27:08,690
planetary that I have seen because of

226
00:27:12,070 --> 00:27:11,180
the level of complexity in detail that

227
00:27:15,460 --> 00:27:12,080
we see here

228
00:27:17,440 --> 00:27:15,470
it's really quite unprecedented other

229
00:27:19,690 --> 00:27:17,450
objects are simply messy but this one

230
00:27:29,470 --> 00:27:19,700
has got all sorts of fascinating

231
00:27:32,050 --> 00:27:29,480
structure well this is a planetary

232
00:27:36,730 --> 00:27:32,060
nebula planetary nebula is sort of a

233
00:27:39,250 --> 00:27:36,740
misnomer actually it's sort of gas cloud

234
00:27:41,680 --> 00:27:39,260
the fireworks that are produced when a

235
00:27:44,260 --> 00:27:41,690
fairly ordinary star reaches the end of

236
00:27:46,000 --> 00:27:44,270
its life and throws its outer layers

237
00:27:47,620 --> 00:27:46,010
into space the reason they're called

238
00:27:49,450 --> 00:27:47,630
planetary nebulae is because in the last

239
00:27:52,210 --> 00:27:49,460
century when people were using small

240
00:27:54,430 --> 00:27:52,220
telescopes some of the small round ones

241
00:27:56,560 --> 00:27:54,440
looked a little bit like the planets

242
00:27:58,660 --> 00:27:56,570
Uranus and Neptune in our solar system

243
00:28:01,870 --> 00:27:58,670
and that's how they picked up that name

244
00:28:03,580 --> 00:28:01,880
but really it is the cloud of gas which

245
00:28:15,010 --> 00:28:03,590
is produced at the end of the star's

246
00:28:19,300 --> 00:28:15,020
lifetime what we see here is a record of

247
00:28:21,160 --> 00:28:19,310
a multi-stage process the actual loss of

248
00:28:24,070 --> 00:28:21,170
the outer layers of the star turns out

249
00:28:27,230 --> 00:28:24,080
to be enormous ly complicated we can see

250
00:28:33,680 --> 00:28:27,240
that at the present time

251
00:28:39,010 --> 00:28:33,690
the star is blowing a bubble it has a a

252
00:28:42,710 --> 00:28:39,020
wind which is flowing rapidly into space

253
00:28:45,020 --> 00:28:42,720
and this tenuous fast wind is sweeping

254
00:28:47,300 --> 00:28:45,030
up the nebula material and constructing

255
00:28:50,390 --> 00:28:47,310
a bubble but outside of that we see this

256
00:28:53,030 --> 00:28:50,400
ring of knots which must correspond to

257
00:28:55,070 --> 00:28:53,040
some earlier stage rejection and further

258
00:28:57,520 --> 00:28:55,080
beyond the boundary of the picture that

259
00:29:00,770 --> 00:28:57,530
we see there's actually an outer halo

260
00:29:05,030 --> 00:29:00,780
furthermore the Jets that we can see in

261
00:29:08,510 --> 00:29:05,040
some of the images represent the very

262
00:29:10,370 --> 00:29:08,520
rapid phase of mass loss which occurs

263
00:29:12,380 --> 00:29:10,380
after the main structures have been

264
00:29:23,530 --> 00:29:12,390
formed so it's an extremely complicated

265
00:29:25,850 --> 00:29:23,540
process for a specialist like myself

266
00:29:29,360 --> 00:29:25,860
there's an enormous amount of detail

267
00:29:31,160 --> 00:29:29,370
that's going to tell us about many

268
00:29:32,780 --> 00:29:31,170
things it's going to tell us about the

269
00:29:34,700 --> 00:29:32,790
kinds of elements that are created in

270
00:29:37,340 --> 00:29:34,710
the last stages of the star's life it's

271
00:29:39,110 --> 00:29:37,350
going to tell us about the ejection

272
00:29:41,180 --> 00:29:39,120
process itself

273
00:29:43,160 --> 00:29:41,190
it raises interesting questions about

274
00:29:45,140 --> 00:29:43,170
how these Jets can form in the last

275
00:29:50,110 --> 00:29:45,150
stages and then change their direction

276
00:29:53,930 --> 00:29:50,120
suddenly but from the point of view of

277
00:29:55,550 --> 00:29:53,940
just the average person I suppose you

278
00:29:59,570 --> 00:29:55,560
could say that it's interesting because

279
00:30:03,110 --> 00:29:59,580
it's a window on our own future it tells

280
00:32:03,520 --> 00:30:03,120
us what is going to happen to a star

281
00:32:15,550 --> 00:32:05,710
or tell me what you're putting in I'm

282
00:32:19,930 --> 00:32:18,250
if you don't go with mark and start

283
00:32:27,760 --> 00:32:19,940
thinking about the positions that stick

284
00:32:29,470 --> 00:32:27,770
this puppy in bad thing about this is

285
00:32:33,070 --> 00:32:29,480
Ron you can cheat and look through it

286
00:32:40,000 --> 00:32:33,080
yeah I understand but you wouldn't do

287
00:32:43,900 --> 00:32:40,010
that come from it I know look at the big

288
00:32:45,970 --> 00:32:43,910
picture here okay looks fairly looks

289
00:32:47,980 --> 00:32:45,980
little to me yeah looks good

290
00:32:50,770 --> 00:32:47,990
okay this dropped me down now mark a

291
00:32:52,240 --> 00:32:50,780
little bit gently don't take me any

292
00:32:54,790 --> 00:32:52,250
forward so I can keep pressure in it

293
00:32:56,920 --> 00:32:54,800
here just dropped me straight down okay

294
00:32:59,920 --> 00:32:56,930
now I can apply pressure back here now

295
00:33:03,550 --> 00:32:59,930
I've got it on the handrail okay let's

296
00:33:07,240 --> 00:33:03,560
go down barn let's just wait till I get

297
00:33:08,980 --> 00:33:07,250
in position now Jen okay okay I've got

298
00:33:11,590 --> 00:33:08,990
it I want to get over on this left side

299
00:33:13,090 --> 00:33:11,600
now I've got it I've got it good hand on

300
00:33:15,400 --> 00:33:13,100
it you can even let go if you have to

301
00:33:17,800 --> 00:33:15,410
want to watch this guy but drop me down

302
00:33:19,450 --> 00:33:17,810
mark can you see the guide rail up there

303
00:33:20,080 --> 00:33:19,460
yep that's what I'm getting down to yes

304
00:33:24,310 --> 00:33:20,090
I can

305
00:33:32,410 --> 00:33:24,320
okay coming down mark you're coming down

306
00:33:34,690 --> 00:33:32,420
mark okay I'm happy Stephen in okay we

307
00:33:37,060 --> 00:33:34,700
we're back at the end of the forward

308
00:33:38,920 --> 00:33:37,070
guide rail we've got to lift it up a

309
00:33:41,500 --> 00:33:38,930
little bit to get onto the Afghan realm

310
00:33:47,280 --> 00:33:41,510
okay come on down then mark well I can

311
00:33:52,500 --> 00:33:49,230
okie-dokie

312
00:33:54,360 --> 00:33:52,510
Oh key whoa here I come

313
00:33:57,520 --> 00:33:54,370
are you clear and I'm gonna help you

314
00:34:04,440 --> 00:34:00,100
okay mark keep bringing me out keep some

315
00:34:06,789 --> 00:34:04,450
pressure on the door Jeff here

316
00:34:10,899 --> 00:34:06,799
possibility that it's cocked slightly

317
00:34:13,030 --> 00:34:10,909
okay okay story yes remember and Cathy

318
00:34:14,740 --> 00:34:13,040
when you get about five foot out you

319
00:34:16,810 --> 00:34:14,750
want to we want to stop take a picture

320
00:34:19,359 --> 00:34:16,820
okay no Katie you want to put a tether

321
00:34:22,180 --> 00:34:19,369
on it I could have a tether okay okay

322
00:34:24,700 --> 00:34:22,190
okay my clear tonight right yes right

323
00:34:27,330 --> 00:34:24,710
level yes you got it okay she's coming

324
00:34:30,220 --> 00:34:27,340
straight out have at it

325
00:34:31,930 --> 00:34:30,230
okay it's clear okay I want a picture

326
00:34:37,210 --> 00:34:31,940
time here no I think you wants you out a

327
00:34:41,050 --> 00:34:37,220
little further b5 quarter-turn t-handles

328
00:34:43,599 --> 00:34:41,060
yes - Cathy you're going to translate

329
00:34:45,460 --> 00:34:43,609
the HSP to the or to the F fixture at

330
00:34:48,190 --> 00:34:45,470
the or you carrier and temporaries throw

331
00:34:50,919 --> 00:34:48,200
the HST by engaging the one pit pin on

332
00:34:55,149 --> 00:34:50,929
the top fork now this does not slide in

333
00:35:00,700 --> 00:34:55,159
sideways a slide in from the top yes

334
00:35:02,109 --> 00:35:00,710
ma'am you got it in right you could if

335
00:35:03,520 --> 00:35:02,119
you were to pick it down now you're okay

336
00:35:05,200 --> 00:35:03,530
Teddy that's the way you want it to go

337
00:35:11,860 --> 00:35:05,210
in I'm talking about down on the a

338
00:35:17,230 --> 00:35:15,280
and if you could roll me 90 to my left

339
00:35:20,340 --> 00:35:17,240
Martin and then go down I'll come in on

340
00:35:25,590 --> 00:35:23,370
and if well that is if the RMS is going

341
00:35:27,990 --> 00:35:25,600
to clear that forward picture I won't be

342
00:35:36,870 --> 00:35:28,000
able to tell you that pain going after

343
00:35:42,180 --> 00:35:36,880
about a foot okay an outboard I need to

344
00:35:54,790 --> 00:35:44,460
if you need me to scoot over there Katie

345
00:35:54,800 --> 00:38:06,210
a story you can tell you're gonna

346
00:38:06,220 --> 00:38:24,640
the other glove is better actually

347
00:38:29,180 --> 00:38:27,770
reach reach down and get those pop - but

348
00:38:30,290 --> 00:38:29,190
if you are into a high doesn't really

349
00:38:31,700 --> 00:38:30,300
matter because this is where we would

350
00:38:34,280 --> 00:38:31,710
take you from there on you would

351
00:38:42,120 --> 00:38:34,290
Saturday see if it is you think far to a

352
00:38:59,870 --> 00:38:45,250
yeah let me do that no statute needs to

353
00:38:59,880 --> 00:39:10,120
doesn't want them stanchion

354
00:39:10,130 --> 00:39:15,760
can we open the radial site

355
00:39:34,600 --> 00:39:19,640
okay well that's okay we're positioned

356
00:39:34,610 --> 00:39:45,060
he's me and Claude

357
00:39:48,210 --> 00:39:46,800
you can have to look there's riding up

358
00:39:49,500 --> 00:39:48,220
on the rail and I need to lift up just a

359
00:39:50,190 --> 00:39:49,510
little bit to get it up on this rail

360
00:39:52,800 --> 00:39:50,200
down here

361
00:39:54,000 --> 00:39:52,810
no Katie can you transition to the LMA

362
00:39:57,330 --> 00:39:54,010
oh yeah you ought to be able to help

363
00:40:01,380 --> 00:39:57,340
down there now Katie yeah but I can't

364
00:40:03,150 --> 00:40:01,390
push much okay hold on a second

365
00:40:04,410 --> 00:40:03,160
bring your end out a little Katie we're

366
00:40:06,390 --> 00:40:04,420
pitching in at the bottom you're way

367
00:40:10,350 --> 00:40:06,400
ahead of me down there hey bring me down

368
00:40:13,080 --> 00:40:10,360
Claud a foot down Claud thank you wait a

369
00:40:22,670 --> 00:40:13,090
second here tone that's a good stuff on

370
00:40:39,720 --> 00:40:37,050
okay let's stop right there all right

371
00:40:41,880 --> 00:40:39,730
budget okay now drop me down Claud where

372
00:40:45,240 --> 00:40:41,890
I get more on the seat you can't push

373
00:40:52,410 --> 00:40:45,250
any I can't push me Paul here hang on a

374
00:40:58,230 --> 00:40:52,420
sec hey bring me up Claud stop they meet

375
00:40:58,590 --> 00:40:58,240
up Klaus stop we had a strap hang in

376
00:41:00,750 --> 00:40:58,600
there

377
00:41:02,850 --> 00:41:00,760
that's Matt be real world what's your

378
00:41:04,410 --> 00:41:02,860
hang-up from who knows bring me up a

379
00:41:12,590 --> 00:41:04,420
little more of is in the way they bring

380
00:41:16,910 --> 00:41:16,160
how they say we're okay now Katie can

381
00:41:27,020 --> 00:41:16,920
you look at it

382
00:41:30,400 --> 00:41:27,030
see y'all eyes if we're okay presently

383
00:41:34,090 --> 00:41:30,410
the technicians the psychic crew are

384
00:41:38,120 --> 00:41:34,100
attempting to align the co-star into the

385
00:41:41,330 --> 00:41:38,130
extender rails and adjusting for pitch

386
00:41:43,210 --> 00:41:41,340
roll and yaw make sure that the co-star

387
00:41:46,130 --> 00:41:43,220
is correctly aligned with the rails

388
00:41:49,160 --> 00:41:46,140
prior to inserting into the - mechanical

389
00:41:53,360 --> 00:41:49,170
simulator well they'll have to make sure

390
00:41:57,060 --> 00:41:53,370
that the rails capture the co-star guide

391
00:41:59,070 --> 00:41:57,070
blocks and rails and so that

392
00:42:03,720 --> 00:41:59,080
when the co-star is correctly aligned it

393
01:00:31,250 --> 00:42:03,730
will insert all the way into the OTA in

394
01:00:37,850 --> 01:00:36,140
three two one and liftoff of the space

395
01:00:41,860 --> 01:00:37,860

396
01:00:44,930 --> 01:00:41,870
Telescope our window on the universe in

397
01:00:47,270 --> 01:00:44,940
1990 ISA and NASA launched the most

398
01:00:50,870 --> 01:00:47,280
powerful astronomical tool ever built

399
01:00:52,700 --> 01:00:50,880
the Hubble Space Telescope since then

400
01:00:54,650 --> 01:00:52,710
astronomers have been making

401
01:00:58,910 --> 01:00:54,660
observations which are at the forefront

402
01:01:00,470 --> 01:00:58,920
of space science in December 1993 space

403
01:01:02,780 --> 01:01:00,480
shuttle Endeavour will link up with

404
01:01:05,170 --> 01:01:02,790
Hubble in orbit to carry out a space

405
01:01:07,820 --> 01:01:05,180
mission never before attempted

406
01:01:10,010 --> 01:01:07,830
astronauts will make several spacewalks

407
01:01:12,980 --> 01:01:10,020
during which they will service the key

408
01:01:15,590 --> 01:01:12,990
components one of our first tasks will

409
01:01:31,230 --> 01:01:15,600
be to replace the solar arrays the power

410
01:01:37,390 --> 01:01:34,600
Hubble has some 50,000 individual solar

411
01:01:40,420 --> 01:01:37,400
cells mounted on its - 12 meter long

412
01:01:42,880 --> 01:01:40,430
solar arrays each cell receives energy

413
01:01:46,960 --> 01:01:42,890
from the sun's rays and converts them

414
01:01:49,510 --> 01:01:46,970
into electricity since the launch in

415
01:01:52,720 --> 01:01:49,520
1990 the arrays have successfully

416
01:01:56,800 --> 01:01:52,730
produced a reliable 4.5 to 5 kilowatts

417
01:01:58,480 --> 01:01:56,810
of output this electricity is used to

418
01:02:00,490 --> 01:01:58,490
power the telescope's scientific

419
01:02:03,730 --> 01:02:00,500
instruments and communication systems

420
01:02:05,980 --> 01:02:03,740
the cells are glued to a blanket which

421
01:02:13,930 --> 01:02:05,990
expands and contracts as the spacecraft

422
01:02:15,970 --> 01:02:13,940
orbits in and out of the Sun radiation

423
01:02:18,880 --> 01:02:15,980
and other processes such as atomic

424
01:02:21,370 --> 01:02:18,890
oxygen erosion however gradually degrade

425
01:02:24,760 --> 01:02:21,380
spacecraft and in particular the

01:02:27,100 --> 01:02:24,770
sensitive solar sounds after four years

427
01:02:29,410 --> 01:02:27,110
in space the arrays are coming to the

428
01:02:32,350 --> 01:02:29,420
end of their useful lifespan and like a

429
01:02:34,270 --> 01:02:32,360
further 49 key components of Hubble they

430
01:02:43,500 --> 01:02:34,280
were designed and are ready to be

431
01:02:48,370 --> 01:02:46,120
though scheduled servicing mission has

432
01:02:50,740 --> 01:02:48,380
given ISA the opportunity to redesign

433
01:02:54,010 --> 01:02:50,750
the solar arrays in order to cure a

434
01:02:55,810 --> 01:02:54,020
curious problem extremely rapid

435
01:02:58,300 --> 01:02:55,820
temperature changes during the sunrise

436
01:03:01,060 --> 01:02:58,310
and sunset together with some friction

437
01:03:03,850 --> 01:03:01,070
effects are causing uneven movement of

438
01:03:05,710 --> 01:03:03,860
the system of pulleys and Springs these

439
01:03:08,710 --> 01:03:05,720
compensate for the expansion and

440
01:03:10,330 --> 01:03:08,720
contraction of the blanket additional

441
01:03:13,150 --> 01:03:10,340
movement is being detected at the drum

for the blanket is anchored at the same

443
01:03:20,580 --> 01:03:15,290
time the temperature changes cause the

444
01:03:25,630 --> 01:03:23,860
this stick-slip movement causes a slight

445
01:03:28,080 --> 01:03:25,640
jitter at the observing end of the

when Hubble observes a distant celestial

448
01:03:36,460 --> 01:03:33,440
object it does so with minut accuracy

449
01:03:39,250 --> 01:03:36,470
the jitter although very small has an

450
01:03:41,260 --> 01:03:39,260
obvious effect imagine looking through a

451
01:03:44,440 --> 01:03:41,270
pair of binoculars whilst traveling

452
01:03:46,180 --> 01:03:44,450
along a bumpy road up to now engineers

453
01:03:49,420 --> 01:03:46,190
have minimized the effect of the jitter

454
01:03:51,490 --> 01:03:49,430
by using special computer software but

455
01:03:55,900 --> 01:03:51,500
this takes up valuable memory capacity

456
01:03:58,030 --> 01:03:55,910
within HSTs onboard computers to make

457
01:04:00,280 --> 01:03:58,040
this capacity available for scientific

458
01:04:02,890 --> 01:04:00,290
purposes and to correct the stick-slip

course before doing that we'll have to

497
01:05:55,049 --> 01:05:51,549
remove the old solar arrays and put them

498
01:05:57,539 --> 01:05:55,059

most sophisticated space astronomical

506
01:06:56,750 --> 01:06:54,510
observatory ever launched by NASA it's

507
01:06:58,539 --> 01:06:56,760
data has already rewritten much of what

508
01:07:01,370 --> 01:06:58,549
we thought we knew about our universe

509
01:07:03,349 --> 01:07:01,380
launched in April of 1990 it carries

510
01:07:05,150 --> 01:07:03,359
five scientific instruments to look at

511
01:07:07,819 --> 01:07:05,160
the universe in both visible light and

512
01:07:09,890 --> 01:07:07,829
the ultraviolet wavelengths one of those

513
01:07:12,799 --> 01:07:09,900
instruments the goddard high-resolution

514
01:07:14,870 --> 01:07:12,809
spectrograph or G hrs for short was

515
01:07:16,700 --> 01:07:14,880
built by Ball corporation's aerospace

516
01:07:19,549 --> 01:07:16,710
and communications group in Boulder

517
01:07:21,589 --> 01:07:19,559
Colorado during orbital checkout however

518
01:07:23,960 --> 01:07:21,599
a flaw was discovered in the telescope's

519
01:07:26,329 --> 01:07:23,970
primary mirror that blurred the images

520
01:07:28,700 --> 01:07:26,339
enough to reduce the image quality to

521
01:07:30,980 --> 01:07:28,710
some instruments and require computer

522
01:07:33,440 --> 01:07:30,990
enhancements it was determined that the

523
01:07:35,660 --> 01:07:33,450
giant 94 inch circular mirror had an

524
01:07:38,270 --> 01:07:35,670
edge that was one ten thousandth of an

525
01:07:40,309 --> 01:07:38,280
inch too low the telescope had been

526
01:07:42,950 --> 01:07:40,319
designed for on-orbit maintenance and

527
01:07:45,500 --> 01:07:42,960
repair over its 15-year life including

528
01:07:48,230 --> 01:07:45,510
replacement of instruments but the giant

529
01:07:50,510 --> 01:07:48,240
mirror was another story then a group of

530
01:07:52,430 --> 01:07:50,520
scientists including optical experts at

531
01:07:54,109 --> 01:07:52,440
ball developed a design for an

532
01:07:56,059 --> 01:07:54,119
instrument that might correct the flaw

533
01:07:58,279 --> 01:07:56,069
when NASA decided to build this

534
01:08:00,710 --> 01:07:58,289
instrument ball was chosen as the prime

535
01:08:02,779 --> 01:08:00,720
contractor balls aerospace group

536
01:08:05,779 --> 01:08:02,789
produced the instrument called co-star

537
01:08:07,370 --> 01:08:05,789
in just 26 months about half the time

538
01:08:09,279 --> 01:08:07,380
considered routine for a space

539
01:08:11,779 --> 01:08:09,289
instrument of its size and complexity

540
01:08:15,349 --> 01:08:11,789
co-star is short for corrective optics

541
01:08:17,390 --> 01:08:15,359
Space Telescope axial replacement if all

542
01:08:19,490 --> 01:08:17,400
goes as planned space shuttle astronauts

543
01:08:22,370 --> 01:08:19,500
will capture the telescope and perform a

544
01:08:25,130 --> 01:08:22,380
variety of tasks on orbit one of those

545
01:08:27,289 --> 01:08:25,140
will be installing co-star once inserted

546
01:08:29,479 --> 01:08:27,299
into place co-star will extend five

547
01:08:31,459 --> 01:08:29,489
pairs of mirrors into the light path

548
01:08:33,979 --> 01:08:31,469
between the flawed mirror and three

549
01:08:36,110 --> 01:08:33,989
other instruments in each pair the first

550
01:08:38,059 --> 01:08:36,120
mirror images the distorted light onto

551
01:08:39,740 --> 01:08:38,069
the second mirror the second mirror is

552
01:08:42,709 --> 01:08:39,750
designed to correct the flaw in the

553
01:08:44,630 --> 01:08:42,719
telescope's primary mirror but by far

554
01:08:46,180 --> 01:08:44,640
the most demanding part of this mission

555
01:08:48,950 --> 01:08:46,190
will follow the crew of Endeavour

556
01:08:51,289 --> 01:08:48,960
astronauts also will have to install new

557
01:08:54,260 --> 01:08:51,299
solar panels a new wide field planetary

558
01:08:57,680 --> 01:08:54,270
camera and install an electronics repair

559
01:08:59,599 --> 01:08:57,690
kit on the G hrs that's why in March of

560
01:09:01,760 --> 01:08:59,609
1993 the crew came

561
01:09:04,039 --> 01:09:01,770
two balls Boulder Colorado operations

562
01:09:07,280 --> 01:09:04,049
for some visual and hands-on training

563
01:09:09,200 --> 01:09:07,290
with co-star ng hrs the astronauts

564
01:09:11,720 --> 01:09:09,210
inspected co-star and discussed how to

565
01:09:14,059 --> 01:09:11,730
handle and install it as well as testing

566
01:09:16,189 --> 01:09:14,069
the tools they will use they also gained

567
01:09:19,160 --> 01:09:16,199
experience with the electronics kit for

568
01:09:21,439 --> 01:09:19,170
the GH RS the upcoming space telescope

569
01:09:22,700 --> 01:09:21,449
servicing mission will no doubt be one

570
01:09:25,070 --> 01:09:22,710
of the most exciting and challenging

571
01:11:14,770 --> 01:09:25,080
ever attempted and Boulder Colorado

572
01:11:20,060 --> 01:11:18,020
after launching it into space NASA and

573
01:11:23,060 --> 01:11:20,070
the nation realized the hubble space

574
01:11:25,839 --> 01:11:23,070
telescope had a perfectly smooth yet

575
01:11:28,609 --> 01:11:25,849
flawed mirror the NASA teams challenge

576
01:11:31,430 --> 01:11:28,619
find the prescription and restore

577
01:11:36,200 --> 01:11:31,440
precision optics on a spacecraft already

578
01:11:38,540 --> 01:11:36,210
flying to fly what you test and test

579
01:11:42,529 --> 01:11:38,550
what you fly would be easier if the

580
01:11:44,569 --> 01:11:42,539
telescope were back on Earth but landing

581
01:11:49,689 --> 01:11:44,579
and relaunching could contaminate the

582
01:11:54,709 --> 01:11:52,279
NASA couldn't test the new corrective

583
01:11:57,200 --> 01:11:54,719
optics in the actual telescope so to

584
01:11:59,149 --> 01:11:57,210
make sure the optics will work the team

585
01:12:01,669 --> 01:11:59,159
had to determine the condition of Hubble

586
01:12:06,109 --> 01:12:01,679
in space and replicate that on the

587
01:12:08,209 --> 01:12:06,119
ground one independent review panel used

588
01:12:10,430 --> 01:12:08,219
Hubble images to determine the precise

589
01:12:14,660 --> 01:12:10,440
shape of the flawed primary mirror and

590
01:12:16,910 --> 01:12:14,670
the prescription to fix it another team

591
01:12:20,569 --> 01:12:16,920
had to verify that the corrective optics

592
01:12:23,120 --> 01:12:20,579
will work teams had to test two optical

593
01:12:25,669 --> 01:12:23,130
packages the replacement wide field

594
01:12:27,830 --> 01:12:25,679
planetary camera and the corrective

595
01:12:31,040 --> 01:12:27,840
optics for the other instruments called

596
01:12:33,529 --> 01:12:31,050
co-star engineers built several

597
01:12:35,510 --> 01:12:33,539
independent analyzers to test that they

598
01:12:39,859 --> 01:12:35,520
had replicated what the Hubble telescope

599
01:12:42,589 --> 01:12:39,869
does to light an independent team here

600
01:12:45,140 --> 01:12:42,599
at Ball Aerospace measured both sets of

601
01:12:49,399 --> 01:12:45,150
optics then we measured the measuring

602
01:12:51,350 --> 01:12:49,409
tools for mechanical testing engineers

603
01:12:53,660 --> 01:12:51,360
built a simulator at Goddard Space

604
01:12:55,729 --> 01:12:53,670
Flight Center using the same precision

605
01:12:58,549 --> 01:12:55,739
equipment that built Hubble originally

606
01:13:00,709 --> 01:12:58,559
the corrective optics and the new camera

607
01:13:02,779 --> 01:13:00,719
attachments were installed so that their

608
01:13:05,750 --> 01:13:02,789
locations duplicate the telescope

609
01:13:08,620 --> 01:13:05,760
attachments within six thousandths of an

610
01:13:11,209 --> 01:13:08,630
inch the thickness of a piece of paper

611
01:13:13,069 --> 01:13:11,219
the clearances are even tighter in the

612
01:13:19,359 --> 01:13:13,079
simulator than they will be on the real

613
01:13:24,080 --> 01:13:22,250
to replicate Hubble during electrical

614
01:13:26,479 --> 01:13:24,090
tests of the corrective optics package

615
01:13:28,189 --> 01:13:26,489
and the new camera an electrical test

616
01:13:30,890 --> 01:13:28,199
facility was built with the same

617
01:13:33,439 --> 01:13:30,900
schematics as the original telescope and

618
01:13:38,510 --> 01:13:33,449
it too was audited by an independent

619
01:13:41,270 --> 01:13:38,520
team all three optical mechanical and

620
01:13:44,149 --> 01:13:41,280
electrical were merged together in a

621
01:13:45,649 --> 01:13:44,159
test of the whole system data from the

622
01:13:48,589 --> 01:13:45,659
tests were sent to the Space Telescope

623
01:13:53,930 --> 01:13:48,599
Science Institute just the way data will

624
01:13:56,660 --> 01:13:53,940
be sent from the telescope hardware has

625
01:13:59,000 --> 01:13:56,670
been thoroughly tested on the ground the

626
01:14:01,339 --> 01:13:59,010
Hubble servicing team is preparing for

627
01:14:04,580 --> 01:14:01,349
contingencies but this mission is a

628
01:14:07,729 --> 01:14:04,590
first so no one can predict everything

629
01:14:45,129 --> 01:14:07,739
that could happen the real test will be

630
01:14:45,139 --> 01:16:07,739
you understand

631
01:16:07,749 --> 01:18:48,350
yes ready

632
01:18:54,840 --> 01:18:52,680
well neutral buoyancy and having been

633
01:18:56,070 --> 01:18:54,850
EBA you get up there and you go out in

634
01:18:57,720 --> 01:18:56,080
the payload Bay and you think you're

635
01:19:00,030 --> 01:18:57,730
right back in the pool I mean it's just

636
01:19:02,100 --> 01:19:00,040
as realistic as you can get and being

637
01:19:03,899 --> 01:19:02,110
able to float around like you do in the

638
01:19:06,180 --> 01:19:03,909
suit so that's the real advantage of it

639
01:19:08,580 --> 01:19:06,190
because you can train almost exactly

640
01:19:10,020 --> 01:19:08,590
like being in space you have a little

641
01:19:12,149 --> 01:19:10,030
bit of drag from the water but you're

642
01:19:14,189 --> 01:19:12,159
able to move around the bay test out the

643
01:19:15,750 --> 01:19:14,199
tools we make them the tools neutrally

644
01:19:17,550 --> 01:19:15,760
buoyant also so you don't have a lot of

645
01:19:19,560 --> 01:19:17,560
a lot of weight and it just gets you

646
01:19:25,169 --> 01:19:19,570
very well prepared to do the job in

647
01:19:27,629 --> 01:19:25,179
orbit well I think everyone remembers

648
01:19:29,340 --> 01:19:27,639
the last Hubble repair mission and what

649
01:19:32,280 --> 01:19:29,350
we're doing right now is we're going

650
01:19:33,689 --> 01:19:32,290
through a series of possible tasks that

651
01:19:35,669 --> 01:19:33,699
they're gonna do on a second servicing

652
01:19:37,500 --> 01:19:35,679
mission so we're trying to do is see if

653
01:19:39,360 --> 01:19:37,510
we need new tools new equipment and

654
01:19:41,490 --> 01:19:39,370
that's the real reason we're here is see

655
01:19:44,220 --> 01:19:41,500
if we have any long lead items to get

656
01:19:46,740 --> 01:19:44,230
ready for that second repair mission and

657
01:19:48,330 --> 01:19:46,750
then later on probably by the end of

658
01:19:50,790 --> 01:19:48,340
this year they're gonna decide exactly

659
01:19:52,560 --> 01:19:50,800
what tasks we're gonna do and the next

660
01:19:54,450 --> 01:19:52,570
series of runs and on in the next year
