1
00:00:00,359 --> 00:00:18,240
but we continue to search

2
00:00:44,950 --> 00:00:27,460
[Music]

3
00:00:44,960 --> 00:00:59,090
original goal

4
00:01:03,590 --> 00:01:00,470
s

5
00:01:06,950 --> 00:01:05,030
you're in for an extraordinary event

6
00:01:08,929 --> 00:01:06,960
today I'm Michelle Thaller from the NASA

7
00:01:11,690 --> 00:01:08,939
Goddard space flight center and this is

8
00:01:13,969 --> 00:01:11,700
live coverage of real-time operations as

9
00:01:15,469 --> 00:01:13,979
Mission managers continue the process of

10
00:01:16,910 --> 00:01:15,479
commissioning the James Webb Space

11
00:01:19,609 --> 00:01:16,920
Telescope

12
00:01:21,109 --> 00:01:19,619
this is a historic event web is the

13
00:01:23,330 --> 00:01:21,119
largest and most complex space

14
00:01:25,850 --> 00:01:23,340
Observatory ever launched and it's

15
00:01:27,890 --> 00:01:25,860
currently more than 650 000 miles away

16
00:01:29,749 --> 00:01:27,900
from Earth traveling out to its final

17
00:01:31,429 --> 00:01:29,759
parking orbit at a point in the solar

18
00:01:33,109 --> 00:01:31,439
system called L2

19
00:01:35,090 --> 00:01:33,119
shortly after it left the plan on

20
00:01:36,830 --> 00:01:35,100
December 25th Engineers have been

21
00:01:38,990 --> 00:01:36,840
following a detailed step-by-step

22
00:01:40,730 --> 00:01:39,000
checklist to get the telescope unfolded

23
00:01:42,350 --> 00:01:40,740
from its initial launch configuration

24
00:01:44,330 --> 00:01:42,360
and that's what brings us to today's

25
00:01:45,649 --> 00:01:44,340
live event

26
00:01:47,510 --> 00:01:45,659
now

27
00:01:49,310 --> 00:01:47,520
today the team plans to complete the

28
00:01:51,350 --> 00:01:49,320
Assembly of the telescope's main mirror

29
00:01:53,090 --> 00:01:51,360
that's this this huge golden eye that

30
00:01:54,109 --> 00:01:53,100
will gather light from distant points in

31
00:01:56,450 --> 00:01:54,119
the universe

32
00:01:59,149 --> 00:01:56,460
and and to be clear this is coverage of

33
00:02:01,190 --> 00:01:59,159
a real-time event so operations are

34
00:02:03,230 --> 00:02:01,200
happening as we speak to you I'm

35
00:02:05,389 --> 00:02:03,240
actually here at the Space Telescope

36
00:02:07,190 --> 00:02:05,399
Science Institute in Baltimore and above

37
00:02:08,809 --> 00:02:07,200
me is the mission operations center or

38
00:02:10,669 --> 00:02:08,819
the mock where people are actually

39
00:02:11,449 --> 00:02:10,679
sending commands to the telescope right

40
00:02:13,910 --> 00:02:11,459
now

41
00:02:16,010 --> 00:02:13,920
because this is a real-time event the

42
00:02:17,869 --> 00:02:16,020
actual schedule and and people that we

43
00:02:20,030 --> 00:02:17,879
have able to talk to us and all of that

44
00:02:21,949 --> 00:02:20,040
is pretty much in flux this is really

45
00:02:23,869 --> 00:02:21,959
happening uh the engineers will decide

46
00:02:26,330 --> 00:02:23,879
when the best times is to send different

47
00:02:28,790 --> 00:02:26,340
commands and we're also operating under

48
00:02:31,430 --> 00:02:28,800
some pretty amazing circumstances we had

49
00:02:33,170 --> 00:02:31,440
this uh incredibly beautiful set built

50
00:02:34,790 --> 00:02:33,180
at Goddard space flight center but then

51
00:02:37,369 --> 00:02:34,800
with the copen search we all went back

52
00:02:38,869 --> 00:02:37,379
to our homes and today I'm isolated in a

53
00:02:40,910 --> 00:02:38,879
room so I can talk to you without a mask

54
00:02:42,410 --> 00:02:40,920
and we're all trying to operate under

55
00:02:44,809 --> 00:02:42,420
these these very extraordinary

56
00:02:46,570 --> 00:02:44,819
conditions but the reason we're doing

57
00:02:48,710 --> 00:02:46,580
this is because this is something

58
00:02:51,229 --> 00:02:48,720
wonderful this is something really

59
00:02:53,270 --> 00:02:51,239
historic this incredible Observatory

60
00:02:54,470 --> 00:02:53,280
this commissioning unfolding of it is

61
00:02:57,050 --> 00:02:54,480
something that's never been done before

62
00:02:58,550 --> 00:02:57,060
and we wanted all of you along with us

63
00:03:00,470 --> 00:02:58,560
as we do this

64
00:03:01,729 --> 00:03:00,480
so today we will have time hopefully to

65
00:03:03,890 --> 00:03:01,739
take some of your questions through

66
00:03:06,290 --> 00:03:03,900
social media via the social media tag

67
00:03:08,210 --> 00:03:06,300
we're asking you to use today is hashtag

68
00:03:12,589 --> 00:03:08,220
unfold the universe

69
00:03:14,809 --> 00:03:12,599
hopefully get to as many of those

70
00:03:17,930 --> 00:03:14,819
questions as we can

71
00:03:19,190 --> 00:03:17,940
so moving on from there

72
00:03:21,710 --> 00:03:19,200
um throughout the process of watching

73
00:03:22,910 --> 00:03:21,720
live throughout the process we're going

74
00:03:24,170 --> 00:03:22,920
to be watching live footage from the

75
00:03:25,869 --> 00:03:24,180
mission operations center at the Space

76
00:03:28,369 --> 00:03:25,879
Telescope Science Institute in Baltimore

77
00:03:31,070 --> 00:03:28,379
and we also have an extraordinary

78
00:03:32,630 --> 00:03:31,080
real-time visualization which is an

79
00:03:34,550 --> 00:03:32,640
animation that's based on Telemetry

80
00:03:36,830 --> 00:03:34,560
actual data coming down from the James

81
00:03:38,630 --> 00:03:36,840
Webb Space Telescope to show us exactly

82
00:03:41,089 --> 00:03:38,640
what configuration the telescope is in

83
00:03:43,250 --> 00:03:41,099
so even though there are no cameras for

84
00:03:45,110 --> 00:03:43,260
us to see what's going on today this uh

85
00:03:47,210 --> 00:03:45,120
this animation will help us see exactly

86
00:03:48,170 --> 00:03:47,220
what's going on when this mirror Wing

87
00:03:50,690 --> 00:03:48,180
that we're going to deploy today

88
00:03:52,009 --> 00:03:50,700
actually gets into place so that will

89
00:03:53,809 --> 00:03:52,019
that will allow us to follow along

90
00:03:55,729 --> 00:03:53,819
pretty much as if we were there

91
00:03:57,170 --> 00:03:55,739
uh today I'm going to be joined by a

92
00:03:59,990 --> 00:03:57,180
collection of experts to help explain

93
00:04:01,670 --> 00:04:00,000
the operations the engineering and of

94
00:04:03,170 --> 00:04:01,680
course the science that this telescope

95
00:04:05,449 --> 00:04:03,180
was designed for because that's the real

96
00:04:07,250 --> 00:04:05,459
reason we're here is that this telescope

97
00:04:09,470 --> 00:04:07,260
was was made to answer some really

98
00:04:11,929 --> 00:04:09,480
extraordinary questions about the

99
00:04:13,670 --> 00:04:11,939
universe and also our own Origins where

100
00:04:16,610 --> 00:04:13,680
everything around us including you and

101
00:04:18,229 --> 00:04:16,620
me comes from and that's really exciting

102
00:04:19,909 --> 00:04:18,239
so uh what you're seeing on the screen

103
00:04:22,069 --> 00:04:19,919
is the real times that we mentioned the

104
00:04:24,530 --> 00:04:22,079
real-time Mission operations center and

105
00:04:27,050 --> 00:04:24,540
also this ovt The Observatory

106
00:04:28,670 --> 00:04:27,060
visualization tool and as we said this

107
00:04:30,469 --> 00:04:28,680
is a simulation that shows you exactly

108
00:04:33,590 --> 00:04:30,479
what it looks like in space

109
00:04:35,450 --> 00:04:33,600
so uh it's based on Telemetry but we

110
00:04:37,010 --> 00:04:35,460
consider this tool to be real time it's

111
00:04:38,749 --> 00:04:37,020
kind of worth mentioning that at the

112
00:04:40,909 --> 00:04:38,759
distance it takes signals to travel it's

113
00:04:42,230 --> 00:04:40,919
about three three light seconds away so

114
00:04:43,969 --> 00:04:42,240
there's a tiny little delay but of

115
00:04:45,170 --> 00:04:43,979
course that won't get in our our way of

116
00:04:47,270 --> 00:04:45,180
covering this

117
00:04:49,909 --> 00:04:47,280
so to begin with um I'm going to be

118
00:04:51,650 --> 00:04:49,919
joined Now by Julie van kampen and Julie

119
00:04:53,090 --> 00:04:51,660
is the Deputy commissioning lead and

120
00:04:55,070 --> 00:04:53,100
she's our gonna be our expert guide

121
00:04:57,950 --> 00:04:55,080
today of much of what's Happening that

122
00:04:59,810 --> 00:04:57,960
we watch unfolding so um Julie welcome

123
00:05:03,230 --> 00:04:59,820
how are you doing today

124
00:05:04,610 --> 00:05:03,240
I'm doing great good morning to you

125
00:05:06,770 --> 00:05:04,620
so one of the things I think that's

126
00:05:09,890 --> 00:05:06,780
worth oh please

127
00:05:12,350 --> 00:05:09,900
uh they're uh also doing well downstairs

128
00:05:16,490 --> 00:05:12,360
they're getting ready to to

129
00:05:19,610 --> 00:05:16,500
have us uh follow along with them

130
00:05:21,350 --> 00:05:19,620
yeah absolutely so um yeah the the the

131
00:05:22,969 --> 00:05:21,360
thing that we're going to be doing today

132
00:05:25,730 --> 00:05:22,979
is that pretty soon they're going to

133
00:05:27,710 --> 00:05:25,740
start unfolding this final wing of the

134
00:05:29,689 --> 00:05:27,720
mirror and when that happens we're going

135
00:05:31,010 --> 00:05:29,699
to be listening to real-time calls from

136
00:05:33,110 --> 00:05:31,020
the mock from the mission operations

137
00:05:34,249 --> 00:05:33,120
center so again what you're looking at

138
00:05:36,650 --> 00:05:34,259
on your screen is you see the mission

139
00:05:38,930 --> 00:05:36,660
operations center above Julie and myself

140
00:05:42,409 --> 00:05:38,940
and then over to the left you see this

141
00:05:44,689 --> 00:05:42,419
uh this uh wonderful simulation and uh

142
00:05:47,150 --> 00:05:44,699
yesterday we had the uh the deployment

143
00:05:49,249 --> 00:05:47,160
of the first of the side wings of the

144
00:05:50,990 --> 00:05:49,259
telescope which happened extremely

145
00:05:52,370 --> 00:05:51,000
successfully it was wonderful to to be

146
00:05:54,770 --> 00:05:52,380
there and today we're going to do the

147
00:05:58,490 --> 00:05:54,780
final Wing uh of the uh of the primary

148
00:06:00,050 --> 00:05:58,500
mirror so as throughout the day as calls

149
00:06:02,270 --> 00:06:00,060
come from the mock we're going to be

150
00:06:03,590 --> 00:06:02,280
pausing conversation so please bear with

151
00:06:05,330 --> 00:06:03,600
us because we might be sort of

152
00:06:06,469 --> 00:06:05,340
mid-conversation and we'll hear some

153
00:06:08,930 --> 00:06:06,479
sort of command that they're issuing

154
00:06:10,070 --> 00:06:08,940
from the mission control here and uh and

155
00:06:11,510 --> 00:06:10,080
we'll stop and make sure we know what's

156
00:06:14,029 --> 00:06:11,520
going on and Julie will give us some

157
00:06:15,409 --> 00:06:14,039
guide to that so uh please uh please

158
00:06:17,090 --> 00:06:15,419
bear with us if that seems a little bit

159
00:06:18,710 --> 00:06:17,100
rough around the edges but I think

160
00:06:21,710 --> 00:06:18,720
that's kind of the fun part about doing

161
00:06:23,689 --> 00:06:21,720
this live so um Julie I just sort of

162
00:06:25,370 --> 00:06:23,699
said it in general but give us some some

163
00:06:28,370 --> 00:06:25,380
more background so so what exactly is

164
00:06:30,409 --> 00:06:28,380
happening today that we're waiting for

165
00:06:32,809 --> 00:06:30,419
sure what they're currently working on

166
00:06:35,270 --> 00:06:32,819
right now is configuring The Observatory

167
00:06:38,450 --> 00:06:35,280
and specifically the the deployment

168
00:06:40,490 --> 00:06:38,460
voter and the uh Actuator motor to make

169
00:06:43,129 --> 00:06:40,500
sure that they are checked out and ready

170
00:06:45,710 --> 00:06:43,139
to go before we start using them so once

171
00:06:49,189 --> 00:06:45,720
those are checked out then we'll fire

172
00:06:51,650 --> 00:06:49,199
the final pins that are holding it in

173
00:06:53,570 --> 00:06:51,660
its launch locked configuration with the

174
00:06:55,850 --> 00:06:53,580
mirrors off to the side and then we'll

175
00:06:57,890 --> 00:06:55,860
use the deployment mirror I'm sorry the

176
00:07:00,589 --> 00:06:57,900
deployment motor to move the mirror into

177
00:07:03,650 --> 00:07:00,599
position and then use the Actuator motor

178
00:07:04,730 --> 00:07:03,660
to lock it into that position

179
00:07:06,589 --> 00:07:04,740
foreign

180
00:07:08,870 --> 00:07:06,599
now this is something that is happening

181
00:07:10,670 --> 00:07:08,880
at extremely cold temperatures uh it was

182
00:07:12,350 --> 00:07:10,680
about uh you know I forget exactly how

183
00:07:14,150 --> 00:07:12,360
many days now we've also lost track of

184
00:07:15,409 --> 00:07:14,160
time I know I think Julia I heard you

185
00:07:18,230 --> 00:07:15,419
saying that you've lost track of whether

186
00:07:20,029 --> 00:07:18,240
it's night or day well you've been sort

187
00:07:22,730 --> 00:07:20,039
of you know in the command center this

188
00:07:25,249 --> 00:07:22,740
whole time but uh we had the the sun

189
00:07:26,990 --> 00:07:25,259
shield deployed and those uh that five

190
00:07:29,029 --> 00:07:27,000
layer sun shield each layer being about

191
00:07:30,950 --> 00:07:29,039
the size of tennis courts it has been

192
00:07:32,990 --> 00:07:30,960
cooling the telescope down blocking the

193
00:07:34,610 --> 00:07:33,000
sunlight and I think you one of the

194
00:07:36,350 --> 00:07:34,620
interesting challenges of these motors

195
00:07:38,450 --> 00:07:36,360
is that these motors are operating at

196
00:07:39,290 --> 00:07:38,460
such low temperatures is that correct

197
00:07:42,290 --> 00:07:39,300
Julie

198
00:07:44,210 --> 00:07:42,300
yeah yeah the uh the motors are designed

199
00:07:47,510 --> 00:07:44,220
to operate at this temperature

200
00:07:49,189 --> 00:07:47,520
um uh however what we do do is have uh

201
00:07:51,650 --> 00:07:49,199
some heaters on them so we can warm them

202
00:07:53,689 --> 00:07:51,660
up to exactly the temperature we want

203
00:07:56,570 --> 00:07:53,699
them at for the deployments because it's

204
00:07:59,749 --> 00:07:56,580
a for contingency you also want to make

205
00:08:02,150 --> 00:07:59,759
sure that you could handle this no

206
00:08:05,270 --> 00:08:02,160
matter how long it took to take out the

207
00:08:07,790 --> 00:08:05,280
sun shield and get that tension so the

208
00:08:10,070 --> 00:08:07,800
actual final temperature of these

209
00:08:12,409 --> 00:08:10,080
assemblies could be very different at

210
00:08:14,689 --> 00:08:12,419
this time depending on how quickly or

211
00:08:16,969 --> 00:08:14,699
slowly those first steps of deployment

212
00:08:19,249 --> 00:08:16,979
went so what we have is we have some

213
00:08:21,230 --> 00:08:19,259
heaters on these motors and and some of

214
00:08:22,969 --> 00:08:21,240
the interfaces to make sure that they're

215
00:08:24,890 --> 00:08:22,979
at the exact temperature

216
00:08:26,809 --> 00:08:24,900
that we know that they can perform very

217
00:08:29,570 --> 00:08:26,819
well so that we have a very reliable

218
00:08:31,129 --> 00:08:29,580
operation today

219
00:08:33,409 --> 00:08:31,139
and just giving people a sense of what

220
00:08:34,790 --> 00:08:33,419
cold is so I know one of the things that

221
00:08:36,889 --> 00:08:34,800
people can do is actually follow along

222
00:08:38,630 --> 00:08:36,899
on a website that's that's where is web

223
00:08:41,149 --> 00:08:38,640
you can actually see where it is on its

224
00:08:43,610 --> 00:08:41,159
Journey out to the LaGrange Point L2 A

225
00:08:45,230 --> 00:08:43,620
Million Miles Away beyond the moon and

226
00:08:46,790 --> 00:08:45,240
you can see where it is there's also a

227
00:08:49,009 --> 00:08:46,800
measurement of temperature as to what

228
00:08:51,410 --> 00:08:49,019
the current temperature is both on the

229
00:08:53,930 --> 00:08:51,420
the warm side of the sun shield and then

230
00:08:55,370 --> 00:08:53,940
the cool side so uh what would what's

231
00:08:58,210 --> 00:08:55,380
our approximate operating temperature

232
00:09:02,329 --> 00:08:58,220
today do you happen to know Julie

233
00:09:05,030 --> 00:09:02,339
I didn't look specifically today at the

234
00:09:06,530 --> 00:09:05,040
uh overall telescope temperatures but we

235
00:09:09,290 --> 00:09:06,540
were running

236
00:09:13,790 --> 00:09:09,300
um down into the structural temperatures

237
00:09:16,009 --> 00:09:13,800
in the almost getting to a 140 Kelvin uh

238
00:09:19,550 --> 00:09:16,019
which I don't do the conversions in my

239
00:09:23,449 --> 00:09:19,560
head I just work in Kelvin

240
00:09:24,530 --> 00:09:23,459
but uh is scientists use and for those

241
00:09:26,630 --> 00:09:24,540
of you out there that don't know that

242
00:09:30,650 --> 00:09:26,640
scale it's the Celsius scale you know

243
00:09:33,889 --> 00:09:30,660
scientists uh use metric and um zero is

244
00:09:35,690 --> 00:09:33,899
defined as absolute zero so when Julie's

245
00:09:38,990 --> 00:09:35,700
talking about she's talking about you

246
00:09:40,970 --> 00:09:39,000
know 140 degrees above absolute zero uh

247
00:09:43,190 --> 00:09:40,980
and uh so so that's that's probably

248
00:09:45,350 --> 00:09:43,200
something well under under 300 degrees

249
00:09:49,070 --> 00:09:45,360
or so or maybe something around there

250
00:09:51,110 --> 00:09:49,080
but but yeah yeah so are there

251
00:09:52,550 --> 00:09:51,120
yeah right now in the mock are they are

252
00:09:54,949 --> 00:09:52,560
they are they checking on those Motors

253
00:09:57,350 --> 00:09:54,959
or what's going on right now

254
00:09:59,030 --> 00:09:57,360
right now in the mock yes they are

255
00:10:01,910 --> 00:09:59,040
checking out those Motors they're doing

256
00:10:04,310 --> 00:10:01,920
the um in the middle of an aliveness

257
00:10:07,069 --> 00:10:04,320
test and then what they do is they they

258
00:10:09,170 --> 00:10:07,079
make sure that the motor is right in the

259
00:10:12,230 --> 00:10:09,180
position that they want to start in

260
00:10:15,530 --> 00:10:13,910
one thing that I was rather surprised at

261
00:10:17,210 --> 00:10:15,540
yesterday during the deployment of the

262
00:10:19,990 --> 00:10:17,220
first Wing was just how quickly that

263
00:10:22,430 --> 00:10:20,000
goes so um today what we're going to see

264
00:10:25,850 --> 00:10:22,440
uh hopefully when they get the command

265
00:10:27,590 --> 00:10:25,860
is a relatively quick movement of the

266
00:10:29,150 --> 00:10:27,600
mirrors it takes it took was it was

267
00:10:31,430 --> 00:10:29,160
about four minutes or so that it took to

268
00:10:34,069 --> 00:10:31,440
actually swing that that Wing around and

269
00:10:35,569 --> 00:10:34,079
then after that comes a long series of

270
00:10:38,150 --> 00:10:35,579
locking it into place

271
00:10:39,530 --> 00:10:38,160
and and as we lock the mirror into place

272
00:10:41,690 --> 00:10:39,540
that's when we'll have a chance to bring

273
00:10:43,430 --> 00:10:41,700
on lots of guests talk a bit about some

274
00:10:45,050 --> 00:10:43,440
of the uh the other things that have

275
00:10:47,990 --> 00:10:45,060
been going on in the mission so that's

276
00:10:51,050 --> 00:10:48,000
that's part of our rundown today

277
00:10:52,550 --> 00:10:51,060
so let's see here

278
00:10:59,389 --> 00:10:52,560
I guess right now we're not getting any

279
00:11:04,550 --> 00:11:02,389
it's about right Julia is it

280
00:11:08,690 --> 00:11:04,560
is it about four minutes for the the

281
00:11:10,730 --> 00:11:08,700
actual uh movement of the mirror itself

282
00:11:12,110 --> 00:11:10,740
the movement of the mirror takes yeah

283
00:11:14,569 --> 00:11:12,120
just a few minutes

284
00:11:16,250 --> 00:11:14,579
um this it's all the setup and the

285
00:11:18,350 --> 00:11:16,260
preparation and the double checks that

286
00:11:20,329 --> 00:11:18,360
they do when they when they finally

287
00:11:23,569 --> 00:11:20,339
start to move the mirror they'll move at

288
00:11:26,389 --> 00:11:23,579
just a small amount just a 1.3 and a

289
00:11:28,610 --> 00:11:26,399
half degrees uh and then they'll stop

290
00:11:30,530 --> 00:11:28,620
and then they'll make sure that they go

291
00:11:32,150 --> 00:11:30,540
through all of their Telemetry to verify

292
00:11:34,069 --> 00:11:32,160
that everything's moving exactly the way

293
00:11:36,230 --> 00:11:34,079
they want before they complete the mood

294
00:11:39,610 --> 00:11:36,240
uh the move of the motor all the way out

295
00:11:44,090 --> 00:11:42,410
and uh I I can sort of think myself as

296
00:11:45,350 --> 00:11:44,100
to why that's a good idea but why was

297
00:11:46,550 --> 00:11:45,360
that particular procedure put in place

298
00:11:48,650 --> 00:11:46,560
that you move the mirror just a little

299
00:11:50,870 --> 00:11:48,660
bit and then and then you go ahead and

300
00:11:52,790 --> 00:11:50,880
make the large movement

301
00:11:56,389 --> 00:11:52,800
yeah if you had any

302
00:11:58,850 --> 00:11:56,399
um concern about your motor or your uh

303
00:12:00,889 --> 00:11:58,860
hinge or possibly any of the soft

304
00:12:03,410 --> 00:12:00,899
structure around it

305
00:12:06,050 --> 00:12:03,420
um being affected by this move you would

306
00:12:09,230 --> 00:12:06,060
want to stop and evaluate before you

307
00:12:10,850 --> 00:12:09,240
moved further you know possibly uh you

308
00:12:13,730 --> 00:12:10,860
needed to run your heater a little bit

309
00:12:16,069 --> 00:12:13,740
more or maybe back up and retry your

310
00:12:19,069 --> 00:12:16,079
your move if you're not seeing the

311
00:12:21,470 --> 00:12:19,079
expected results so there's a whole

312
00:12:24,050 --> 00:12:21,480
series of telemetry that we get we have

313
00:12:25,810 --> 00:12:24,060
so much instrumentation

314
00:12:29,449 --> 00:12:25,820
um all over the telescope whether it's

315
00:12:31,250 --> 00:12:29,459
motor Telemetry thermal telemetry

316
00:12:33,470 --> 00:12:31,260
whether it's

317
00:12:36,410 --> 00:12:33,480
um indications that the entire

318
00:12:39,050 --> 00:12:36,420
spacecraft has seen

319
00:12:43,129 --> 00:12:39,060
oh now we hear our

320
00:12:48,290 --> 00:12:45,170
so as you hear the control room speak

321
00:12:51,410 --> 00:12:48,300
you'll hear a couple of people uh

322
00:12:54,829 --> 00:12:51,420
talking a lot uh there's our deployment

323
00:12:57,769 --> 00:12:54,839
bleed uh she'll be walking through the

324
00:13:00,190 --> 00:12:57,779
procedures to handle all of the steps

325
00:13:03,290 --> 00:13:00,200
and going back and forth with our

326
00:13:05,710 --> 00:13:03,300
operational control center our flight

327
00:13:08,509 --> 00:13:05,720
control room our OC in the front room

328
00:13:10,970 --> 00:13:08,519
and if you look on your top picture

329
00:13:14,690 --> 00:13:10,980
they'll be the person and that

330
00:13:16,610 --> 00:13:14,700
closest row all the way in the center of

331
00:13:18,230 --> 00:13:16,620
the actually it's going to be to the

332
00:13:20,690 --> 00:13:18,240
right of everyone's screen but she's in

333
00:13:22,430 --> 00:13:20,700
the center there and she's the

334
00:13:24,170 --> 00:13:22,440
operational controller and she works

335
00:13:26,750 --> 00:13:24,180
with our deployment lead to walk through

336
00:13:27,829 --> 00:13:26,760
all the steps of today's procedure one

337
00:13:29,769 --> 00:13:27,839
by one

338
00:13:32,569 --> 00:13:29,779
you'll hear them talk back and forth

339
00:13:35,269 --> 00:13:32,579
confirm everything and every step along

340
00:13:37,550 --> 00:13:35,279
the way they'll they'll talk about what

341
00:13:40,550 --> 00:13:37,560
is into the command line and that means

342
00:13:42,530 --> 00:13:40,560
what has been put onto the the

343
00:13:44,449 --> 00:13:42,540
workstation in front of them and before

344
00:13:47,269 --> 00:13:44,459
the command is sent up to the

345
00:13:49,730 --> 00:13:47,279
observatory the deployment will check

346
00:13:52,970 --> 00:13:49,740
and verify that it's configured properly

347
00:13:55,250 --> 00:13:52,980
and written properly and ready to go and

348
00:13:57,170 --> 00:13:55,260
hit send and then once they hit send in

349
00:13:58,910 --> 00:13:57,180
the and the script starts you'll hear a

350
00:14:00,850 --> 00:13:58,920
lot of times that the script will

351
00:14:03,710 --> 00:14:00,860
confirm that it's been

352
00:14:06,050 --> 00:14:03,720
received and it then the next step will

353
00:14:07,910 --> 00:14:06,060
be to hit go it's like a lot of times on

354
00:14:11,389 --> 00:14:07,920
Windows it will say do you really want

355
00:14:12,889 --> 00:14:11,399
to do this so you have to say yes twice

356
00:14:14,569 --> 00:14:12,899
okay

357
00:14:16,910 --> 00:14:14,579
and I understand we're about four

358
00:14:19,490 --> 00:14:16,920
minutes uh from getting the command to

359
00:14:21,230 --> 00:14:19,500
start releasing to uh release to fire as

360
00:14:22,430 --> 00:14:21,240
they say so that will be happening

361
00:14:23,870 --> 00:14:22,440
pretty soon

362
00:14:26,030 --> 00:14:23,880
um another one of the people that you

363
00:14:27,410 --> 00:14:26,040
often hear called out is is sometimes

364
00:14:29,269 --> 00:14:27,420
it's a little bit funny to hear is is

365
00:14:31,670 --> 00:14:29,279
Mom you know he'll he'll say somebody

366
00:14:33,470 --> 00:14:31,680
that referred to as Mom and then tell us

367
00:14:36,050 --> 00:14:33,480
who that is Julie

368
00:14:37,970 --> 00:14:36,060
that's the mission operations manager

369
00:14:41,210 --> 00:14:37,980
and you'll hear him from time to time

370
00:14:43,310 --> 00:14:41,220
come on and do a poll of all of the

371
00:14:45,949 --> 00:14:43,320
various subsystems that are uh

372
00:14:49,069 --> 00:14:45,959
supporting today like the spacecraft

373
00:14:50,810 --> 00:14:49,079
um and the instruments uh Team sure that

374
00:14:52,910 --> 00:14:50,820
everyone's ready to go on with a major

375
00:14:54,829 --> 00:14:52,920
step as we go through our our

376
00:14:58,610 --> 00:14:54,839
deployments today

377
00:15:01,069 --> 00:14:58,620
um so he he's the uh overall lead of

378
00:15:04,389 --> 00:15:01,079
both the front and the back room so the

379
00:15:07,250 --> 00:15:04,399
back room is our spacecraft and our

380
00:15:09,949 --> 00:15:07,260
subsystems that that support that's that

381
00:15:12,110 --> 00:15:09,959
we also have a second back room which we

382
00:15:15,230 --> 00:15:12,120
call the SI room which has our

383
00:15:20,470 --> 00:15:16,970
in fact I think that person on screen

384
00:15:23,150 --> 00:15:20,480
that I see now is is Bill Oaks

385
00:15:25,370 --> 00:15:23,160
yeah exactly that's right so tell us a

386
00:15:26,810 --> 00:15:25,380
bit about Bill Oaks Bill Oaks role in

387
00:15:30,470 --> 00:15:26,820
this mission

388
00:15:33,710 --> 00:15:30,480
he's the program manager for jwst

389
00:15:35,749 --> 00:15:33,720
um and he's uh over over the whole

390
00:15:37,550 --> 00:15:35,759
program both the operation side the

391
00:15:39,170 --> 00:15:37,560
development side

392
00:15:41,810 --> 00:15:39,180
um

393
00:15:44,210 --> 00:15:41,820
everybody eventually works for Bill as

394
00:15:46,129 --> 00:15:44,220
you go up our chain so he's been great

395
00:15:47,810 --> 00:15:46,139
and he probably doesn't even know that

396
00:15:49,370 --> 00:15:47,820
he's currently on camera

397
00:15:51,470 --> 00:15:49,380
it's

398
00:15:53,990 --> 00:15:51,480
so one of the things that people were

399
00:15:55,370 --> 00:15:54,000
asking uh before is is how are we

400
00:15:56,629 --> 00:15:55,380
actually getting this information down

401
00:15:58,069 --> 00:15:56,639
from the spacecraft so you mentioned

402
00:15:59,629 --> 00:15:58,079
that there's Telemetry there are

403
00:16:01,610 --> 00:15:59,639
detectors all over the spacecraft

404
00:16:03,110 --> 00:16:01,620
measuring things like electrical current

405
00:16:04,850 --> 00:16:03,120
or temperature or all of these things

406
00:16:06,530 --> 00:16:04,860
but how is that data actually getting to

407
00:16:07,910 --> 00:16:06,540
us here at the Space Telescope Science

408
00:16:10,310 --> 00:16:07,920
Institute

409
00:16:13,370 --> 00:16:10,320
oh that's that's an interesting point so

410
00:16:17,030 --> 00:16:13,380
we have uh antennas on our Observatory

411
00:16:19,370 --> 00:16:17,040
and if people have watched along one of

412
00:16:21,170 --> 00:16:19,380
our very early deployments was was one

413
00:16:22,310 --> 00:16:21,180
of our antennas

414
00:16:26,829 --> 00:16:22,320
um and

415
00:16:30,230 --> 00:16:26,839
from that it is a signal is transmitted

416
00:16:31,970 --> 00:16:30,240
down to the deep space Network so this

417
00:16:35,810 --> 00:16:31,980
is the same network that we communicate

418
00:16:38,870 --> 00:16:35,820
with let's say the Mars rover uh on its

419
00:16:42,769 --> 00:16:38,880
uh there's a one in Canberra there's one

420
00:16:46,970 --> 00:16:42,779
in Madrid there's one in uh Goldstone uh

421
00:16:50,150 --> 00:16:46,980
and these um very large dishes then take

422
00:16:52,249 --> 00:16:50,160
that signal converted into something

423
00:16:54,829 --> 00:16:52,259
that can be sent on a ground Network and

424
00:16:56,810 --> 00:16:54,839
it's sent by ground Network to here

425
00:16:59,210 --> 00:16:56,820
where we were both we were both the

426
00:17:00,650 --> 00:16:59,220
Space Telescope Science Institute and

427
00:17:04,909 --> 00:17:00,660
the

428
00:17:06,949 --> 00:17:04,919
it goes through a whole series of

429
00:17:09,169 --> 00:17:06,959
processing and then it comes up to our

430
00:17:11,990 --> 00:17:09,179
screens and monitors in a way that we

431
00:17:15,309 --> 00:17:12,000
can interpret uh completed successfully

432
00:17:20,569 --> 00:17:18,590
693.027 bottom one door sink

433
00:17:27,890 --> 00:17:20,579
the command line looks good you're going

434
00:17:32,990 --> 00:17:30,409
and you're good that was the last

435
00:17:36,110 --> 00:17:33,000
if you have

436
00:17:38,810 --> 00:17:36,120
that was the last set of commands sent

437
00:17:40,370 --> 00:17:38,820
to get the motors ready before we to

438
00:17:42,350 --> 00:17:40,380
verify that the motors are ready before

439
00:17:46,510 --> 00:17:42,360
we go ahead and do the lock on our

440
00:17:52,490 --> 00:17:50,450
and manager Don John Vernon

441
00:17:54,890 --> 00:17:52,500
oh I'm not sure

442
00:17:56,690 --> 00:17:54,900
what is his signs that this is

443
00:17:59,390 --> 00:17:56,700
commissioning manager but he's the

444
00:18:02,090 --> 00:17:59,400
deputy project manager he works directly

445
00:18:05,750 --> 00:18:03,650
I believe we're about two minutes now

446
00:18:07,130 --> 00:18:05,760
away from firing for those of you who

447
00:18:10,310 --> 00:18:07,140
may have just joined us you're watching

448
00:18:12,169 --> 00:18:10,320
at live coverage of the unfolding of the

449
00:18:13,850 --> 00:18:12,179
primary mirror of for the James Webb

450
00:18:16,490 --> 00:18:13,860
Space Telescope yesterday they

451
00:18:18,169 --> 00:18:16,500
successfully unfolded one of the Wings I

452
00:18:20,570 --> 00:18:18,179
believe that was the port the left side

453
00:18:22,490 --> 00:18:20,580
wing and today we are doing the final

454
00:18:24,470 --> 00:18:22,500
Wing which will hopefully by the end of

455
00:18:27,409 --> 00:18:24,480
the day leave the primary mirror

456
00:18:29,270 --> 00:18:27,419
completely extended and unfolded so

457
00:18:32,510 --> 00:18:29,280
we're only a few minutes away from that

458
00:18:34,070 --> 00:18:32,520
command to uh to start first slowly and

459
00:18:36,470 --> 00:18:34,080
then and then a little bit more quickly

460
00:18:38,090 --> 00:18:36,480
unfolding that one of the telescope and

461
00:18:39,590 --> 00:18:38,100
you can see the configuration the

462
00:18:42,350 --> 00:18:39,600
telescope is in the left side of your

463
00:18:44,930 --> 00:18:42,360
screen this is a computer image but it's

464
00:18:46,730 --> 00:18:44,940
based on actual real-time data from The

465
00:18:48,049 --> 00:18:46,740
Observatory so this is what web would

466
00:18:49,549 --> 00:18:48,059
look like if you were out there to see

467
00:18:52,669 --> 00:18:49,559
it of course it would also look a lot

468
00:18:55,250 --> 00:18:52,679
darker because the uh the sun shield now

469
00:18:56,990 --> 00:18:55,260
is completely blocking uh light from the

470
00:18:58,669 --> 00:18:57,000
sun and any sort of heat from the Earth

471
00:19:00,470 --> 00:18:58,679
and the moon and the telescope is

472
00:19:01,730 --> 00:19:00,480
operating very dark and very cold as it

473
00:19:03,770 --> 00:19:01,740
was designed to do

474
00:19:05,150 --> 00:19:03,780
so we're very close

475
00:19:06,890 --> 00:19:05,160
I believe the calls will be coming

476
00:19:09,169 --> 00:19:06,900
shortly so we will uh we'll probably

477
00:19:10,730 --> 00:19:09,179
take a pause on conversation now and uh

478
00:19:12,770 --> 00:19:10,740
and begin listening to the calls and and

479
00:19:14,750 --> 00:19:12,780
Julie as as we have time in the

480
00:19:16,250 --> 00:19:14,760
conversation and the calls come uh

481
00:19:19,070 --> 00:19:16,260
please step in to tell us what those

482
00:19:20,630 --> 00:19:19,080
commands mean and be our interpreter so

483
00:19:25,490 --> 00:19:20,640
that we know how this uh how this

484
00:19:29,150 --> 00:19:27,770
to say it's tremendously exciting for me

485
00:19:32,270 --> 00:19:29,160
um you know I have been looking forward

486
00:19:33,770 --> 00:19:32,280
to this quite literally for decades uh

487
00:19:36,289 --> 00:19:33,780
and uh you know this is something that

488
00:19:38,870 --> 00:19:36,299
is uh has been a part of my my family uh

489
00:19:40,370 --> 00:19:38,880
have worked on this so this is a very

490
00:19:57,529 --> 00:19:40,380
proud and very exciting moment for me

491
00:20:01,730 --> 00:19:59,150
Julie how are you feeling I know

492
00:20:03,590 --> 00:20:01,740
yesterday we ended up smiling a lot as

493
00:20:06,470 --> 00:20:03,600
we as we as we saw that we move into

494
00:20:08,570 --> 00:20:06,480
place big smiles I I know that um you

495
00:20:09,710 --> 00:20:08,580
know one of the things that was uh uh

496
00:20:11,810 --> 00:20:09,720
tremendously important to the the

497
00:20:19,610 --> 00:20:11,820
unfolding of this telescope

498
00:20:19,620 --> 00:20:27,649
I

499
00:20:33,230 --> 00:20:29,890
am the only one left right

500
00:20:34,909 --> 00:20:33,240
I have confirmation from definitely that

501
00:20:36,950 --> 00:20:34,919
they agree that all of the pink moves

502
00:20:39,409 --> 00:20:36,960
look good we're ready to command the

503
00:20:40,870 --> 00:20:39,419
launch lock releases they're ready to go

504
00:20:44,330 --> 00:20:40,880
with

505
00:20:46,549 --> 00:20:44,340
693.029 all Channel 5 verified

506
00:20:54,289 --> 00:20:46,559
the command line looks good your go to

507
00:20:54,299 --> 00:21:04,370
you go to continue

508
00:21:07,669 --> 00:21:05,750
and at this point they're going to send

509
00:21:11,270 --> 00:21:07,679
the command with

510
00:21:13,909 --> 00:21:11,280
um puts a current through a fuse wire

511
00:21:16,490 --> 00:21:13,919
and releases the launch locks that are

512
00:21:20,210 --> 00:21:16,500
holding the side of the mirrors back

513
00:21:22,010 --> 00:21:20,220
against the structure of the back plane

514
00:21:24,350 --> 00:21:22,020
of the mirror and that was done so that

515
00:21:26,450 --> 00:21:24,360
we fit inside our fairing of our

516
00:21:29,029 --> 00:21:26,460
telescope we were all folded up like

517
00:21:30,409 --> 00:21:29,039
origami obviously the sun shield has

518
00:21:33,409 --> 00:21:30,419
been deployed and you can see how big

519
00:21:35,810 --> 00:21:33,419
that is relative to the to the mirror

520
00:21:38,630 --> 00:21:35,820
itself right now so the last of this is

521
00:21:40,789 --> 00:21:38,640
to bring out the mirrors and uh

522
00:21:44,450 --> 00:21:40,799
then we will have our telescope near

523
00:21:47,630 --> 00:21:46,190
and that's what makes this such a

524
00:21:49,610 --> 00:21:47,640
historic moment is that this is the

525
00:21:52,070 --> 00:21:49,620
first time we've unfolded such a large

526
00:21:54,470 --> 00:21:52,080
space Observatory and uh you know first

527
00:21:56,149 --> 00:21:54,480
came the the sun shield uh then there

528
00:21:58,070 --> 00:21:56,159
was the uh the secondary mirror the

529
00:21:59,630 --> 00:21:58,080
focus the focusing mirror that had to

530
00:22:02,029 --> 00:21:59,640
come out in front of the telescope to

531
00:22:04,070 --> 00:22:02,039
focus the light and then yesterday the

532
00:22:07,190 --> 00:22:04,080
uh the first of the the primary mirror

533
00:22:09,890 --> 00:22:07,200
side segments the wings and uh and then

534
00:22:11,570 --> 00:22:09,900
today the second one of that uh this

535
00:22:12,830 --> 00:22:11,580
this will not be the end today of

536
00:22:14,810 --> 00:22:12,840
commissioning the telescope there's

537
00:22:16,730 --> 00:22:14,820
still more to come one of the major

538
00:22:18,950 --> 00:22:16,740
things that needs to happen next is the

539
00:22:21,529 --> 00:22:18,960
focusing of the mirror the mirror has 18

540
00:22:23,690 --> 00:22:21,539
segments that all work independently and

541
00:22:25,430 --> 00:22:23,700
can all be adjusted independently and

542
00:22:27,169 --> 00:22:25,440
we'll talk more about that after we

543
00:22:28,730 --> 00:22:27,179
unfold the uh the wing segment we'll

544
00:22:30,890 --> 00:22:28,740
have some time to talk with some guests

545
00:22:32,690 --> 00:22:30,900
to talk about that but uh but that's the

546
00:22:34,370 --> 00:22:32,700
the incredible thing is that this large

547
00:22:37,070 --> 00:22:34,380
Observatory was folded up to fit inside

548
00:22:39,130 --> 00:22:37,080
the rocket the Ariane 5 rocket launched

549
00:22:41,810 --> 00:22:39,140
from uh Kuru French Guiana South America

550
00:22:43,669 --> 00:22:41,820
and and now we are unfolding this

551
00:22:45,710 --> 00:22:43,679
Observatory and this is the the first

552
00:22:47,690 --> 00:22:45,720
time this particular procedure has been

553
00:22:51,409 --> 00:22:47,700
done in space and this is this is just a

554
00:22:54,770 --> 00:22:52,909
so you were mentioning that there had

555
00:22:56,750 --> 00:22:54,780
you you send a current through these

556
00:22:58,130 --> 00:22:56,760
these is this an example of the

557
00:23:00,770 --> 00:22:58,140
actuators that we've been talking about

558
00:23:02,390 --> 00:23:00,780
before that uh they they're they're

559
00:23:04,250 --> 00:23:02,400
actuators that have to release or this

560
00:23:07,250 --> 00:23:04,260
is something a little bit different

561
00:23:08,510 --> 00:23:07,260
no this is this is the same um

562
00:23:09,169 --> 00:23:08,520
these are like

563
00:23:12,230 --> 00:23:09,179
uh

564
00:23:14,270 --> 00:23:12,240
um a pin that's held in a in a like a

565
00:23:17,930 --> 00:23:14,280
cup cone assembly

566
00:23:21,409 --> 00:23:17,940
um and when the uh fuse wire breaks it

567
00:23:23,930 --> 00:23:21,419
it loosens up our wire that's tightly

568
00:23:26,510 --> 00:23:23,940
wound around it allowing the pin and the

569
00:23:28,669 --> 00:23:26,520
cup to separate all that all those

570
00:23:31,430 --> 00:23:28,679
little components are captured into the

571
00:23:34,250 --> 00:23:31,440
mechanism cell itself so none of it's

572
00:23:36,950 --> 00:23:34,260
free-floating in space is debris but um

573
00:23:39,110 --> 00:23:36,960
it allows those two pieces to move apart

574
00:23:43,130 --> 00:23:39,120
um and there's going to be four that

575
00:23:52,909 --> 00:23:46,190
they're just about ready to continue

576
00:23:52,919 --> 00:23:58,789
she says go to execute executing

577
00:24:08,149 --> 00:24:00,830
and you're go to enable

578
00:24:12,350 --> 00:24:10,549
and what they'll see now in their

579
00:24:15,470 --> 00:24:12,360
Telemetry is they might see a

580
00:24:17,990 --> 00:24:15,480
disturbance on the entire Observatory of

581
00:24:21,169 --> 00:24:18,000
of these launch blocks actually coming

582
00:24:24,110 --> 00:24:21,179
apart the entire Observatory might just

583
00:24:26,750 --> 00:24:24,120
just like when you um unlock your

584
00:24:28,970 --> 00:24:26,760
vehicle you can hear the click of the

585
00:24:32,029 --> 00:24:28,980
door unlocked there's almost like a

586
00:24:33,769 --> 00:24:32,039
little vibe in the whole structure that

587
00:24:37,010 --> 00:24:33,779
comes through

588
00:24:42,049 --> 00:24:37,020
um to that that we can sometimes we can

589
00:24:42,059 --> 00:24:57,049
that these are fully released

590
00:25:00,529 --> 00:24:58,789
in fact I know the design of these

591
00:25:02,510 --> 00:25:00,539
actuators was specifically done so that

592
00:25:04,310 --> 00:25:02,520
they don't jar the telescope very much

593
00:25:05,690 --> 00:25:04,320
they're actually very gentle yes but but

594
00:25:07,490 --> 00:25:05,700
even just that that little bit of

595
00:25:09,169 --> 00:25:07,500
vibration could be detected and firm

596
00:25:11,930 --> 00:25:09,179
armed or waiting on this fourth command

597
00:25:17,409 --> 00:25:14,570
and the stories command sequence

598
00:25:21,250 --> 00:25:17,419
is we don't ever want to break a command

599
00:25:25,010 --> 00:25:21,260
between the time we tell it to Fire and

600
00:25:26,149 --> 00:25:25,020
all stations our next go will uh fire

601
00:25:27,710 --> 00:25:26,159
ordinance

602
00:25:30,169 --> 00:25:27,720
OTE

603
00:25:54,190 --> 00:25:30,179
um lrm group seven

604
00:25:54,200 --> 00:25:57,649
all right

605
00:25:57,659 --> 00:26:02,230
yeah thank you

606
00:26:05,690 --> 00:26:04,190
I believe the music you're hearing

607
00:26:08,169 --> 00:26:05,700
that's real that's in the control room

608
00:26:10,490 --> 00:26:08,179
they're uh yeah

609
00:26:13,490 --> 00:26:10,500
I actually hear it twice because I have

610
00:26:15,049 --> 00:26:13,500
the my my earphone on and then I hear it

611
00:26:16,730 --> 00:26:15,059
through here so I had a hard time

612
00:26:19,250 --> 00:26:16,740
figuring out if you could really hear it

613
00:26:24,350 --> 00:26:19,260
if it was just me for a second

614
00:26:28,850 --> 00:26:26,149
there's obviously an air of excitement

615
00:26:30,470 --> 00:26:28,860
you know and uh you know certainly you

616
00:26:32,990 --> 00:26:30,480
know everybody is a little bit uh you

617
00:26:34,789 --> 00:26:33,000
know the nerves are you know on edge but

618
00:26:37,310 --> 00:26:34,799
but lots of optimism lots of excitement

619
00:26:39,409 --> 00:26:37,320
and lots of smiles so that's uh it's an

620
00:26:41,210 --> 00:26:39,419
emotional moment for all of us

621
00:26:42,890 --> 00:26:41,220
everyone's been working on this since

622
00:26:45,710 --> 00:26:42,900
the day of launch that our launch

623
00:26:47,450 --> 00:26:45,720
deployments started uh with our very

624
00:26:49,490 --> 00:26:47,460
first one that uh

625
00:26:53,029 --> 00:26:49,500
um was caught by the

626
00:26:55,430 --> 00:26:53,039
rocket itself as it floated jwc floated

627
00:26:58,010 --> 00:26:55,440
away from it the upper stage and it's

628
00:27:02,450 --> 00:26:58,020
been non-stop day after day since then

629
00:27:05,049 --> 00:27:02,460
uh having each deployment come along in

630
00:27:08,390 --> 00:27:05,059
series everyone has gone very well

631
00:27:12,710 --> 00:27:08,400
so I can confirm safe and disabled and

632
00:27:12,720 --> 00:27:16,010
still do that

633
00:27:19,789 --> 00:27:17,870
this is the step to actually do the

634
00:27:23,090 --> 00:27:19,799
environment line look good this is for

635
00:27:24,409 --> 00:27:23,100
OTE lrm group eight and you are going to

636
00:27:26,750 --> 00:27:24,419
execute

637
00:27:29,389 --> 00:27:26,760
coffee to see you have to go certificate

638
00:27:31,430 --> 00:27:29,399
executing

639
00:27:35,630 --> 00:27:31,440
and you're going to continue

640
00:27:41,269 --> 00:27:38,210
there's a total of four mechanisms that

641
00:27:43,549 --> 00:27:41,279
do the launch lock uh two are at the

642
00:27:46,490 --> 00:27:43,559
hinge where the uh which is actually

643
00:27:48,649 --> 00:27:46,500
closest to us in the display at the

644
00:27:50,750 --> 00:27:48,659
joints one at the top one at the bottom

645
00:27:53,690 --> 00:27:50,760
and then two kind of hold the wing back

646
00:27:55,669 --> 00:27:53,700
to keep it from rattling during launch

647
00:27:58,850 --> 00:27:55,679
um and are at the at the Far Corners

648
00:28:02,450 --> 00:27:58,860
yeah I can confirm enough

649
00:28:02,460 --> 00:28:20,810
you see Optical term

650
00:28:27,769 --> 00:28:23,210
I can confirm armed waiting for the

651
00:28:30,769 --> 00:28:29,930
I think that's so amazing to me is that

652
00:28:32,690 --> 00:28:30,779
this

653
00:28:36,590 --> 00:28:32,700
what's happening today is the is the end

654
00:28:38,510 --> 00:28:36,600
of the of 178 release mechanisms you

655
00:28:40,610 --> 00:28:38,520
know every single one had to work all

656
00:28:41,630 --> 00:28:40,620
stations authorizations our next go it

657
00:28:44,510 --> 00:28:41,640
will fire

658
00:28:47,409 --> 00:28:44,520
um o t e lrm group eight

659
00:28:54,470 --> 00:28:47,419
OC you are go to fire

660
00:28:57,649 --> 00:28:56,090
yeah this uh

661
00:28:59,389 --> 00:28:57,659
there was a lot of work to put into

662
00:29:01,730 --> 00:28:59,399
these a lot of people have heard about

663
00:29:03,529 --> 00:29:01,740
our single point failures each one of

664
00:29:06,110 --> 00:29:03,539
these itself was a single point failure

665
00:29:08,029 --> 00:29:06,120
in other words if one of those four uh

666
00:29:11,510 --> 00:29:08,039
launch releases does not release it

667
00:29:14,570 --> 00:29:11,520
we're not able to move this uh side of

668
00:29:17,389 --> 00:29:14,580
the mirror forward into position uh so

669
00:29:18,889 --> 00:29:17,399
this would be our last of these four uh

670
00:29:20,570 --> 00:29:18,899
single point failures there's there's

671
00:29:23,210 --> 00:29:20,580
still other single point failures and

672
00:29:24,529 --> 00:29:23,220
some some that stay with us for the life

673
00:29:27,769 --> 00:29:24,539
of the mission

674
00:29:29,930 --> 00:29:27,779
um different areas of structure or a

675
00:29:32,510 --> 00:29:29,940
mechanism that the mechanism fails we

676
00:29:34,970 --> 00:29:32,520
don't we don't have a second path of

677
00:29:35,990 --> 00:29:34,980
light to bring the light down but these

678
00:29:38,510 --> 00:29:36,000
are major

679
00:29:45,830 --> 00:29:38,520
milestones and getting the observatory

680
00:29:49,130 --> 00:29:47,029
for those of you who are joining us

681
00:29:50,570 --> 00:29:49,140
you're looking at live coverage of the

682
00:29:52,850 --> 00:29:50,580
commissioning of the James Webb Space

683
00:29:54,529 --> 00:29:52,860
Telescope today we are unfolding the

684
00:29:56,210 --> 00:29:54,539
second of the wings of the primary

685
00:29:58,490 --> 00:29:56,220
mirrors

686
00:30:00,710 --> 00:29:58,500
joining with joining me is Julie van

687
00:30:02,990 --> 00:30:00,720
kampen she is the Deputy commissioning

688
00:30:07,630 --> 00:30:03,000
engineer

689
00:30:10,610 --> 00:30:07,640
and see people there excited and happy

690
00:30:11,810 --> 00:30:10,620
mom copies thanks Steph lead glad to

691
00:30:14,690 --> 00:30:11,820
have the plot so we could follow along

692
00:30:18,049 --> 00:30:14,700
share your enthusiasm that's awesome 178

693
00:30:20,330 --> 00:30:18,059
out of 178 congratulations

694
00:30:22,250 --> 00:30:20,340
thank you they just fired

695
00:30:30,430 --> 00:30:22,260
it confirms that all of those mechanisms

696
00:30:36,230 --> 00:30:33,789
we're ready to continue with

697
00:30:38,510 --> 00:30:36,240
693.032.eu to stand by

698
00:30:40,570 --> 00:30:38,520
I'll be there

699
00:30:49,730 --> 00:30:40,580
and they could see indications

700
00:30:49,740 --> 00:30:59,630
and you're going to continue

701
00:31:03,529 --> 00:31:01,310
the next couple steps are going to be

702
00:31:05,570 --> 00:31:03,539
getting the um the deployment Motors

703
00:31:07,190 --> 00:31:05,580
ready again so before they check them

704
00:31:09,950 --> 00:31:07,200
out they had to put them into a standby

705
00:31:11,990 --> 00:31:09,960
mode while they were doing the firing uh

706
00:31:14,810 --> 00:31:12,000
that was the safe configuration that you

707
00:31:16,190 --> 00:31:14,820
heard the deployment lead speak to now

708
00:31:19,070 --> 00:31:16,200
they're going to get them back into the

709
00:31:29,750 --> 00:31:19,080
configuration and then uh they'll get

710
00:31:35,409 --> 00:31:32,690
you actually I can confirm uh burn

711
00:31:37,730 --> 00:31:35,419
standby round robin we're ready for

712
00:31:40,730 --> 00:31:37,740
693.033 to

713
00:31:42,470 --> 00:31:40,740
um restore default torque limits

714
00:31:43,909 --> 00:31:42,480
the command line looks good you're going

715
00:31:49,250 --> 00:31:43,919
to execute

716
00:31:55,970 --> 00:31:50,950
and you're going to continue

717
00:32:00,350 --> 00:31:58,370
and earlier we had mentioned uh the

718
00:32:03,110 --> 00:32:00,360
position called Mom a submission

719
00:32:04,970 --> 00:32:03,120
operations manager and the elbow we're

720
00:32:08,930 --> 00:32:04,980
seeing in the top screen and that's Carl

721
00:32:20,870 --> 00:32:08,940
Starr who's the mama jwst

722
00:32:26,810 --> 00:32:23,389
when they do the small mirror move the

723
00:32:28,190 --> 00:32:26,820
small motor move on the mirror here in

724
00:32:28,850 --> 00:32:28,200
our uh

725
00:32:30,889 --> 00:32:28,860
um

726
00:32:33,049 --> 00:32:30,899
and our tool that we get to see on the

727
00:32:35,090 --> 00:32:33,059
screen the ovt The Observatory

728
00:32:37,250 --> 00:32:35,100
visualization tool we don't actually

729
00:32:39,950 --> 00:32:37,260
it's such a small move we won't see the

730
00:32:42,049 --> 00:32:39,960
tool actually uh change at all it won't

731
00:32:44,450 --> 00:32:42,059
be until the major move before we can

732
00:32:46,549 --> 00:32:44,460
actually see it on this tool

733
00:32:48,649 --> 00:32:46,559
and it looks like they're calculating

734
00:32:51,169 --> 00:32:48,659
that's going to be another 20 or more

735
00:32:52,850 --> 00:32:51,179
minutes until we actually see the full

736
00:33:04,370 --> 00:32:52,860
move take place

737
00:33:08,210 --> 00:33:06,590
we're sitting here now with worksheet uh

738
00:33:10,009 --> 00:33:08,220
watching the uh the mission operation

739
00:33:11,389 --> 00:33:10,019
manager and you'll also be seeing live

740
00:33:13,190 --> 00:33:11,399
coverage from the mock the mission

741
00:33:15,289 --> 00:33:13,200
operations center at the Space Telescope

742
00:33:18,470 --> 00:33:15,299
Science Institute in Baltimore Maryland

743
00:33:20,690 --> 00:33:18,480
I'm there as well although in a uh in an

744
00:33:22,310 --> 00:33:20,700
isolated conference room so I can speak

745
00:33:24,230 --> 00:33:22,320
to you unmasked

746
00:33:26,990 --> 00:33:24,240
of course we're operating under coveted

747
00:33:29,330 --> 00:33:27,000
protocols which has made a challenge but

748
00:33:31,070 --> 00:33:29,340
uh it's a happy and and festive day here

749
00:33:36,529 --> 00:33:31,080
and uh we are we're really looking

750
00:33:39,470 --> 00:33:38,149
later on in the program we'll have a

751
00:33:41,389 --> 00:33:39,480
chance to take some of your questions

752
00:33:43,909 --> 00:33:41,399
from social media and today we're asking

753
00:33:46,190 --> 00:33:43,919
you to use the hashtag unfold the

754
00:33:51,529 --> 00:33:46,200
universe so on hashtag unfold the

755
00:33:56,509 --> 00:33:53,570
we'll be stopping our commentaries with

756
00:33:58,130 --> 00:33:56,519
your commands so uh you know we may have

757
00:34:00,409 --> 00:33:58,140
a conversation but then we'll stop to

758
00:34:02,389 --> 00:34:00,419
hear how the commands are progressing as

759
00:34:04,490 --> 00:34:02,399
first they make a very small movement to

760
00:34:05,690 --> 00:34:04,500
make sure the wing is uh is moving

761
00:34:07,549 --> 00:34:05,700
correctly and all the motors are

762
00:34:10,069 --> 00:34:07,559
functioning correctly and then in about

763
00:34:11,510 --> 00:34:10,079
20 minutes from now you will see uh on

764
00:34:13,250 --> 00:34:11,520
the uh on the left hand side of your

765
00:34:15,470 --> 00:34:13,260
screen you will actually see the wing

766
00:34:18,710 --> 00:34:15,480
click into place and then after that

767
00:34:20,750 --> 00:34:18,720
there will be a couple hours of uh of

768
00:34:23,450 --> 00:34:20,760
latching it of making sure that this is

769
00:34:28,609 --> 00:34:23,460
fully in it's extended permanent

770
00:34:32,329 --> 00:34:30,409
I see Julie's got a big smile on her

771
00:34:37,369 --> 00:34:32,339
face which I I love to see because uh

772
00:34:37,379 --> 00:34:42,470
um

773
00:34:46,849 --> 00:34:45,290
Bill Oaks is the program manager and uh

774
00:34:49,250 --> 00:34:46,859
you'll uh you'll see him throughout this

775
00:34:50,569 --> 00:34:49,260
as Julie said in the he's sort of the

776
00:34:53,389 --> 00:34:50,579
the head of the mission everybody kind

777
00:34:55,069 --> 00:34:53,399
of reports to him at this point

778
00:34:57,589 --> 00:34:55,079
there's an interesting

779
00:34:59,569 --> 00:34:57,599
um uh teamwork between scientists and

780
00:35:00,770 --> 00:34:59,579
Engineers on a mission like this and

781
00:35:03,530 --> 00:35:00,780
actually Julie and I were talking about

782
00:35:04,670 --> 00:35:03,540
this earlier that uh you know I come

783
00:35:06,230 --> 00:35:04,680
from the background of being an

784
00:35:08,150 --> 00:35:06,240
astrophysicist and and when I think

785
00:35:09,950 --> 00:35:08,160
about web I mainly think of all of the

786
00:35:11,510 --> 00:35:09,960
incredible data and the questions the

787
00:35:13,130 --> 00:35:11,520
scientific questions that I I'm looking

788
00:35:15,410 --> 00:35:13,140
forward to being able to explore with

789
00:35:17,990 --> 00:35:15,420
the telescope uh Julie has a very

790
00:35:20,450 --> 00:35:18,000
different perspective Julie tell us a

791
00:35:22,670 --> 00:35:20,460
bit about your your position as the uh

792
00:35:25,510 --> 00:35:22,680
the deputy commissioning engineer tell

793
00:35:28,790 --> 00:35:25,520
us about what that what that job entails

794
00:35:30,109 --> 00:35:28,800
sure as the deputy commissioning

795
00:35:32,990 --> 00:35:30,119
engineer

796
00:35:35,690 --> 00:35:33,000
um I've worked to try to make sure all

797
00:35:38,390 --> 00:35:35,700
of the various pieces that it takes to

798
00:35:42,829 --> 00:35:38,400
commission the telescope come together

799
00:35:46,069 --> 00:35:42,839
um in a way that uh makes an engineering

800
00:35:48,109 --> 00:35:46,079
sense so there's a lot of people who uh

801
00:35:50,530 --> 00:35:48,119
have worked many many years to make sure

802
00:35:54,310 --> 00:35:50,540
that it comes together operationally

803
00:35:59,089 --> 00:35:54,320
working with how the commands are sent

804
00:36:01,130 --> 00:35:59,099
how the the control is done of the

805
00:36:03,530 --> 00:36:01,140
observatory making sure our

806
00:36:06,530 --> 00:36:03,540
Communications with the Ascend is is

807
00:36:07,550 --> 00:36:06,540
worked out and timed with all of our

808
00:36:10,490 --> 00:36:07,560
activities

809
00:36:12,770 --> 00:36:10,500
but I I deal with the

810
00:36:13,990 --> 00:36:12,780
um engineering aspect of that to make

811
00:36:18,530 --> 00:36:14,000
sure that

812
00:36:20,569 --> 00:36:18,540
if things are happening in a faster

813
00:36:23,750 --> 00:36:20,579
sense that will

814
00:36:25,970 --> 00:36:23,760
still be safe like our operations can be

815
00:36:28,430 --> 00:36:25,980
handled uh two days earlier or two days

816
00:36:30,650 --> 00:36:28,440
later should the timeline move one way

817
00:36:34,310 --> 00:36:30,660
or another from a hardware perspective

818
00:36:36,710 --> 00:36:34,320
uh so I I you know so many people are

819
00:36:38,210 --> 00:36:36,720
very interested in how the signs will

820
00:36:40,310 --> 00:36:38,220
work but I'm interested in how the parts

821
00:36:42,290 --> 00:36:40,320
of the telescope work themselves to make

822
00:36:45,530 --> 00:36:42,300
sure that they work together to actually

823
00:36:49,910 --> 00:36:47,990
thank you and uh you know that that's

824
00:36:51,349 --> 00:36:49,920
the the question of course about you

825
00:36:52,970 --> 00:36:51,359
know how you become an engineer or how

826
00:36:54,650 --> 00:36:52,980
you become a scientist

827
00:36:56,450 --> 00:36:54,660
um well what what is your background I

828
00:36:57,530 --> 00:36:56,460
mean what what do you have a degree in

829
00:36:59,210 --> 00:36:57,540
for example that led you to this

830
00:37:01,550 --> 00:36:59,220
particular job

831
00:37:03,829 --> 00:37:01,560
uh my actual degree both my

832
00:37:06,890 --> 00:37:03,839
undergraduate and I have a master's

833
00:37:10,670 --> 00:37:06,900
degree in mechanical engineering uh and

834
00:37:12,890 --> 00:37:10,680
basically I started off uh being

835
00:37:16,310 --> 00:37:12,900
interested in in how to design and build

836
00:37:17,950 --> 00:37:16,320
things uh as a kid I like to to build

837
00:37:20,990 --> 00:37:17,960
forts

838
00:37:24,050 --> 00:37:21,000
uh you know you name it I like to put it

839
00:37:26,210 --> 00:37:24,060
together so uh I went to school to be a

840
00:37:28,910 --> 00:37:26,220
mechanical engineer graduated from

841
00:37:31,430 --> 00:37:28,920
school my first uh company was a small

842
00:37:33,650 --> 00:37:31,440
it was a small company so it kind of got

843
00:37:35,390 --> 00:37:33,660
to do a little bit of everything so you

844
00:37:38,510 --> 00:37:35,400
kind of learned to be the Jill of all

845
00:37:41,390 --> 00:37:38,520
trades uh and from that I moved to NASA

846
00:37:43,550 --> 00:37:41,400
and uh got into into the testing

847
00:37:44,870 --> 00:37:43,560
department and was able to do actually a

848
00:37:47,390 --> 00:37:44,880
lot of the Hubble servicing missions

849
00:37:49,190 --> 00:37:47,400
from from the testing side to get those

850
00:37:50,569 --> 00:37:49,200
instruments and components that were

851
00:37:52,609 --> 00:37:50,579
being

852
00:37:54,950 --> 00:37:52,619
um sent to Hubble on the on the

853
00:37:57,710 --> 00:37:54,960
different servicing missions ready for

854
00:38:00,470 --> 00:37:57,720
those uh missions

855
00:38:04,370 --> 00:38:00,480
uh then eventually I moved over to jwst

856
00:38:06,290 --> 00:38:04,380
and I've been on jwst since 2003 and

857
00:38:08,569 --> 00:38:06,300
I've been a systems engineer on the

858
00:38:11,270 --> 00:38:08,579
instruments and then the payload and now

859
00:38:13,130 --> 00:38:11,280
onto the commissioning

860
00:38:15,109 --> 00:38:13,140
wonderful

861
00:38:17,329 --> 00:38:15,119
so we will pause our commentary when we

862
00:38:19,069 --> 00:38:17,339
see your commands from the uh the

863
00:38:20,390 --> 00:38:19,079
mission operations center but we do have

864
00:38:23,450 --> 00:38:20,400
time to take a few questions on social

865
00:38:24,950 --> 00:38:23,460
media so um whenever people ask

866
00:38:26,569 --> 00:38:24,960
questions like this I'm I'm touching

867
00:38:28,490 --> 00:38:26,579
wood right now it says it's as Nicholas

868
00:38:29,690 --> 00:38:28,500
on Twitter asks would the Observer store

869
00:38:31,609 --> 00:38:29,700
would the observatory still be

870
00:38:32,810 --> 00:38:31,619
operational if one or a few of the

871
00:38:34,849 --> 00:38:32,820
mirrors break

872
00:38:37,190 --> 00:38:34,859
is there anything out there that could

873
00:38:38,210 --> 00:38:37,200
break them so I mean so that there's

874
00:38:40,010 --> 00:38:38,220
maybe a couple of different ways to

875
00:38:41,510 --> 00:38:40,020
answer this I mean what what happens all

876
00:38:43,609 --> 00:38:41,520
of the mirrors will be aimed

877
00:38:45,290 --> 00:38:43,619
independently what happens if for

878
00:38:46,609 --> 00:38:45,300
example one of them doesn't aim

879
00:38:49,250 --> 00:38:46,619
correctly

880
00:38:50,690 --> 00:38:49,260
well the great thing about the the web

881
00:38:52,310 --> 00:38:50,700
telescope is with these independent

882
00:38:54,349 --> 00:38:52,320
mirrors is that

883
00:38:57,829 --> 00:38:54,359
um we can handle so many different

884
00:39:01,609 --> 00:38:57,839
scenarios like that uh for instance if

885
00:39:05,390 --> 00:39:01,619
um one of the mirrors either let's say a

886
00:39:08,210 --> 00:39:05,400
a piece of debris hits it or during its

887
00:39:10,430 --> 00:39:08,220
launch and Ascent phase uh some of the

888
00:39:13,670 --> 00:39:10,440
stresses were higher than predicted and

889
00:39:16,250 --> 00:39:13,680
and we had a problem that that broke a

890
00:39:17,990 --> 00:39:16,260
mirror or an actuator uh behind the

891
00:39:20,930 --> 00:39:18,000
mirror we could actually take that in

892
00:39:23,930 --> 00:39:20,940
your essentially out of the image

893
00:39:26,750 --> 00:39:23,940
by making it very much out of focus with

894
00:39:29,150 --> 00:39:26,760
the rest of the telescope and uh you

895
00:39:31,910 --> 00:39:29,160
know if anyone's ever experienced having

896
00:39:35,210 --> 00:39:31,920
a floater in their eye or or something

897
00:39:37,569 --> 00:39:35,220
uh like a scratch one on your eye you

898
00:39:40,190 --> 00:39:37,579
can you can realize how much you can see

899
00:39:43,569 --> 00:39:40,200
and it is completely unaffected by that

900
00:39:46,730 --> 00:39:43,579
so when something's not quite

901
00:39:49,370 --> 00:39:46,740
in sync with the rest of of the primary

902
00:39:51,589 --> 00:39:49,380
mirror there's there's different ways to

903
00:39:53,630 --> 00:39:51,599
take that impact out some of it's

904
00:39:55,730 --> 00:39:53,640
physically by moving the mirror out of

905
00:39:57,890 --> 00:39:55,740
its focus and some of it's digitally by

906
00:40:00,770 --> 00:39:57,900
knowing that there's a uh imperfection

907
00:40:03,589 --> 00:40:00,780
that's going to be in each and every

908
00:40:06,470 --> 00:40:03,599
um uh image that gets subtracted out

909
00:40:07,730 --> 00:40:06,480
digitally from those images

910
00:40:09,770 --> 00:40:07,740
thank you

911
00:40:11,030 --> 00:40:09,780
maybe another social media question for

912
00:40:12,589 --> 00:40:11,040
those of you that would like to uh

913
00:40:14,870 --> 00:40:12,599
actually have questions uh answered live

914
00:40:16,730 --> 00:40:14,880
on air with us use the hashtag unfold

915
00:40:18,349 --> 00:40:16,740
the universe so we'll be looking for

916
00:40:20,270 --> 00:40:18,359
hashtag unfold the universe take your

917
00:40:23,630 --> 00:40:20,280
questions on social media

918
00:40:25,190 --> 00:40:23,640
and so uh this actually kind of uh goes

919
00:40:27,290 --> 00:40:25,200
along with the second one so Michael on

920
00:40:29,390 --> 00:40:27,300
Facebook asks what protects the mirror

921
00:40:30,650 --> 00:40:29,400
from micrometeors and other fine space

922
00:40:32,710 --> 00:40:30,660
dust debris

923
00:40:35,410 --> 00:40:32,720
I think the answer is

924
00:40:38,390 --> 00:40:35,420
not much nothing

925
00:40:42,890 --> 00:40:38,400
what you see is what you get

926
00:40:46,190 --> 00:40:42,900
um the this this the sun shield

927
00:40:48,890 --> 00:40:46,200
um is facing the the Earth and the Sun

928
00:40:50,150 --> 00:40:48,900
so not only does it protect it a little

929
00:40:51,829 --> 00:40:50,160
bit from

930
00:40:55,250 --> 00:40:51,839
um

931
00:40:57,710 --> 00:40:55,260
from a little bit of possibly Duster or

932
00:40:59,990 --> 00:40:57,720
anything coming from the Sun but you

933
00:41:03,589 --> 00:41:00,000
know the heat of the sun is basically

934
00:41:05,450 --> 00:41:03,599
what it does if the sun shield itself

935
00:41:07,309 --> 00:41:05,460
you know this isn't quite the question

936
00:41:10,130 --> 00:41:07,319
he asked but if the sun shield itself

937
00:41:11,930 --> 00:41:10,140
got hit by a micrometeoroid

938
00:41:13,849 --> 00:41:11,940
um and got a little tear or a rip in it

939
00:41:17,390 --> 00:41:13,859
we have that's part of why we have five

940
00:41:20,450 --> 00:41:17,400
layers and we can tolerate so much

941
00:41:22,010 --> 00:41:20,460
um damage throughout time and it was

942
00:41:25,190 --> 00:41:22,020
part of our lifetime calculations to

943
00:41:27,290 --> 00:41:25,200
make sure based on

944
00:41:30,109 --> 00:41:27,300
um our little bit of knowledge that we

945
00:41:33,410 --> 00:41:30,119
have of other observatories at the L2

946
00:41:34,990 --> 00:41:33,420
point to make sure that the the

947
00:41:38,450 --> 00:41:35,000
environment there

948
00:41:40,910 --> 00:41:38,460
can be sustained by all of our Optics

949
00:41:44,930 --> 00:41:40,920
and all of our sun shield over the time

950
00:41:47,990 --> 00:41:46,730
and just to give you an update you're

951
00:41:49,730 --> 00:41:48,000
looking at live commissioning of the

952
00:41:51,589 --> 00:41:49,740
James Webb Space Telescope from what I

953
00:41:54,589 --> 00:41:51,599
understand uh there will be a call in

954
00:41:55,910 --> 00:41:54,599
about four minutes releasing the uh the

955
00:41:57,770 --> 00:41:55,920
larger mechanism and about four minutes

956
00:42:00,710 --> 00:41:57,780
after that we should be able to see the

957
00:42:02,510 --> 00:42:00,720
wings start to move so in uh now in a

958
00:42:03,770 --> 00:42:02,520
bit under 10 minutes we'll see the wing

959
00:42:06,109 --> 00:42:03,780
move

960
00:42:08,109 --> 00:42:06,119
in the first release at this time we're

961
00:42:12,170 --> 00:42:08,119
ready to continue with

962
00:42:17,089 --> 00:42:12,180
693.034 deu to operate frame six

963
00:42:17,099 --> 00:42:22,910
executed

964
00:42:30,349 --> 00:42:25,970
and you're going to continue

965
00:42:34,910 --> 00:42:32,809
when they do the small move this will

966
00:42:36,770 --> 00:42:34,920
verify for sure and for certain that all

967
00:42:39,050 --> 00:42:36,780
of those launch release mechanisms have

968
00:42:41,270 --> 00:42:39,060
released and that the mirror is free to

969
00:42:44,450 --> 00:42:41,280
move into its final position

970
00:42:48,470 --> 00:42:46,550
continuing our conversation I mean in

971
00:42:50,990 --> 00:42:48,480
some small impacts for micrometeorites

972
00:42:52,970 --> 00:42:51,000
will happen you know over the lifetime

973
00:42:55,130 --> 00:42:52,980
of the mission there there will be some

974
00:42:57,650 --> 00:42:55,140
damage to the uh the the the mirrors of

975
00:42:59,930 --> 00:42:57,660
the telescope I I remember

976
00:43:01,490 --> 00:42:59,940
um I The Goddard space flight center

977
00:43:03,290 --> 00:43:01,500
when they replaced some of the cameras

978
00:43:04,670 --> 00:43:03,300
on the Huddle Space Telescope they

979
00:43:07,010 --> 00:43:04,680
brought some of the old cameras back for

980
00:43:09,770 --> 00:43:07,020
an hour can they confirm operation

981
00:43:12,410 --> 00:43:09,780
framework and we're ready to continue

982
00:43:19,910 --> 00:43:12,420
with the small motor move

983
00:43:22,609 --> 00:43:20,870
the window

984
00:43:24,230 --> 00:43:22,619
that command line looks good you're

985
00:43:26,150 --> 00:43:24,240
going to execute

986
00:43:29,150 --> 00:43:26,160
I'll be back you see you have to go to

987
00:43:33,910 --> 00:43:29,160
skip executing

988
00:43:40,490 --> 00:43:37,190
there we go

989
00:43:48,170 --> 00:43:40,500
and stand by probably review parameter

990
00:43:53,630 --> 00:43:51,470
so we were talking about the the degree

991
00:43:54,950 --> 00:43:53,640
um also being at L2 is very useful

992
00:43:56,390 --> 00:43:54,960
parameters what good you're going to

993
00:44:03,109 --> 00:43:56,400
move the motor

994
00:44:07,849 --> 00:44:05,450
complete

995
00:44:20,329 --> 00:44:07,859
the above copies and you can queue up

996
00:44:20,339 --> 00:44:59,150
and The Meta status is moving

997
00:45:02,270 --> 00:45:01,370
I'm singing got it I remember the uh the

998
00:45:04,790 --> 00:45:02,280
camera is being brought back for

999
00:45:06,770 --> 00:45:04,800
analysis they were uh they were you know

1000
00:45:08,510 --> 00:45:06,780
analyzing every tiny tiny little crater

1001
00:45:10,670 --> 00:45:08,520
that was made by a little piece of dust

1002
00:45:12,650 --> 00:45:10,680
or a little piece of debris so but you

1003
00:45:14,150 --> 00:45:12,660
said that L2 for example is actually a

1004
00:45:16,069 --> 00:45:14,160
very nice place to be it's actually a

1005
00:45:17,990 --> 00:45:16,079
kind of a cleaner place when it comes to

1006
00:45:21,530 --> 00:45:18,000
space jump because is that correct yes

1007
00:45:24,650 --> 00:45:21,540
yes uh low earth orbit tubble is in is

1008
00:45:26,150 --> 00:45:24,660
is uh has a lot of space debris as

1009
00:45:27,730 --> 00:45:26,160
everybody has seen the move things

1010
00:45:30,710 --> 00:45:27,740
gravity

1011
00:45:32,930 --> 00:45:30,720
execute stop deploy

1012
00:45:35,569 --> 00:45:32,940
copy that since you have about your

1013
00:45:37,910 --> 00:45:35,579
suggests XK

1014
00:45:42,109 --> 00:45:37,920
and you're going to continue but we're

1015
00:45:42,119 --> 00:45:53,690
they're stopping the motor move now

1016
00:45:58,190 --> 00:45:56,569
and I see the matter of thought

1017
00:46:02,990 --> 00:45:58,200
that this time we're ready to continue

1018
00:46:06,170 --> 00:46:03,000
with uh 693.041 deu to stand by

1019
00:46:07,730 --> 00:46:06,180
but looks good you are good to execute

1020
00:46:11,329 --> 00:46:07,740
right there if you have the

1021
00:46:11,339 --> 00:46:25,190
and you're going to continue

1022
00:46:29,270 --> 00:46:27,050
once they've taken a moment to analyze

1023
00:46:31,250 --> 00:46:29,280
their Telemetry and then move on again

1024
00:46:33,349 --> 00:46:31,260
with the mirror moves uh they're going

1025
00:46:36,170 --> 00:46:33,359
to take the motor and they're going to

1026
00:46:37,309 --> 00:46:36,180
drive the mirror up against a hard stop

1027
00:46:38,990 --> 00:46:37,319
all

1028
00:46:40,790 --> 00:46:39,000
once they move it up against the hard

1029
00:46:42,470 --> 00:46:40,800
stop and they verify that they they're

1030
00:46:45,050 --> 00:46:42,480
happy with that position then they're

1031
00:46:46,430 --> 00:46:45,060
going to start moving some latch latches

1032
00:46:47,809 --> 00:46:46,440
into position

1033
00:46:49,370 --> 00:46:47,819
but when they move the latches into

1034
00:46:51,109 --> 00:46:49,380
position they'll kind of back off on

1035
00:46:53,270 --> 00:46:51,119
that deployment motor a little bit to

1036
00:46:54,490 --> 00:46:53,280
make sure that the latches are the ones

1037
00:46:57,589 --> 00:46:54,500
that

1038
00:46:59,710 --> 00:46:57,599
can confirm standby round robin at this

1039
00:47:03,290 --> 00:46:59,720
time we're ready to continue with

1040
00:47:04,970 --> 00:47:03,300
693.042 to restore the gainsmap

1041
00:47:07,010 --> 00:47:04,980
parameter to default

1042
00:47:08,450 --> 00:47:07,020
that command line looks good you are

1043
00:47:11,930 --> 00:47:08,460
going to continue

1044
00:47:11,940 --> 00:47:20,990
executing

1045
00:47:27,049 --> 00:47:23,210
sending some configuration commands to

1046
00:47:30,049 --> 00:47:28,730
so once again you're joining us for the

1047
00:47:31,549 --> 00:47:30,059
live commissioning of the James Webb

1048
00:47:35,329 --> 00:47:31,559
Space Telescope

1049
00:47:37,430 --> 00:47:35,339
the uh the starboard wing of the primary

1050
00:47:38,510 --> 00:47:37,440
mirror is being deployed today in just a

1051
00:47:40,490 --> 00:47:38,520
few minutes we should be able to

1052
00:47:41,809 --> 00:47:40,500
actually see it moving on the left-hand

1053
00:47:43,910 --> 00:47:41,819
side of your screen is a real-time

1054
00:47:46,069 --> 00:47:43,920
visualization based on Telemetry Based

1055
00:47:48,049 --> 00:47:46,079
on data from the telescope it's uh it's

1056
00:47:49,250 --> 00:47:48,059
generated by a computer this is not a

1057
00:47:51,470 --> 00:47:49,260
camera we do not have cameras

1058
00:47:52,670 --> 00:47:51,480
unfortunately on board web but this will

1059
00:47:55,069 --> 00:47:52,680
show us the configuration that's

1060
00:47:56,450 --> 00:47:55,079
actually in in real time and in just a

1061
00:47:59,089 --> 00:47:56,460
few minutes from now we will begin

1062
00:48:02,270 --> 00:47:59,099
actually bringing that side part of the

1063
00:48:04,490 --> 00:48:02,280
primary mirror around to form one large

1064
00:48:06,650 --> 00:48:04,500
mirror of 18 segments

1065
00:48:08,270 --> 00:48:06,660
segments that you see are colored gold

1066
00:48:10,130 --> 00:48:08,280
which we'll talk more about the mirrors

1067
00:48:12,349 --> 00:48:10,140
after we do this deployment we'll have

1068
00:48:13,910 --> 00:48:12,359
some time as the the telescope is

1069
00:48:16,910 --> 00:48:13,920
latched into its into its final

1070
00:48:19,250 --> 00:48:16,920
configuration but that uh that is uh

1071
00:48:21,470 --> 00:48:19,260
actual gold very very thin coating of

1072
00:48:23,450 --> 00:48:21,480
gold just a few hundred atoms thick

1073
00:48:24,770 --> 00:48:23,460
and uh

1074
00:48:26,089 --> 00:48:24,780
the telescope would actually look quite

1075
00:48:27,770 --> 00:48:26,099
a bit darker than you see in that

1076
00:48:29,809 --> 00:48:27,780
animation that the sun shield is

1077
00:48:31,730 --> 00:48:29,819
blocking out all of the light from the

1078
00:48:33,829 --> 00:48:31,740
sun and any reflected light from the

1079
00:48:35,390 --> 00:48:33,839
Earth and the moon and and so those

1080
00:48:39,650 --> 00:48:35,400
mirrors right now are exposed to the

1081
00:48:41,450 --> 00:48:39,660
dark cold space that will be uh doing

1082
00:48:49,609 --> 00:48:41,460
its primary science you know looking out

1083
00:48:57,230 --> 00:48:51,230
I understand the call to move is

1084
00:49:00,890 --> 00:48:59,089
and when the uh the mirror begins to

1085
00:49:03,950 --> 00:49:00,900
move we will just uh I'll sit back

1086
00:49:05,930 --> 00:49:03,960
together and enjoy watching that and uh

1087
00:49:08,690 --> 00:49:05,940
we'll come back with commentary uh after

1088
00:49:10,970 --> 00:49:08,700
that has completed and uh we have some

1089
00:49:13,430 --> 00:49:10,980
time as a latch telescope a couple of

1090
00:49:15,470 --> 00:49:13,440
hours uh into its final configuration so

1091
00:49:17,030 --> 00:49:15,480
we'll have different guests and experts

1092
00:49:25,670 --> 00:49:17,040
to uh to talk about what's going on when

1093
00:49:30,890 --> 00:49:27,950
I'm joined by Julie van kampen and she's

1094
00:49:46,430 --> 00:49:30,900
the deputy Observatory commissioning

1095
00:49:52,250 --> 00:49:48,890
rtcp is complete

1096
00:49:54,109 --> 00:49:52,260
because of and devops copies that looks

1097
00:49:56,170 --> 00:49:54,119
like that load completed successfully

1098
00:50:00,650 --> 00:49:56,180
we're ready to continue with

1099
00:50:03,349 --> 00:50:00,660
693.043 be to operate frame six

1100
00:50:05,030 --> 00:50:03,359
oh is that on the window and the command

1101
00:50:06,770 --> 00:50:05,040
line looks good you're going to execute

1102
00:50:11,329 --> 00:50:06,780
project

1103
00:50:16,790 --> 00:50:12,890
so they've just put that you're going to

1104
00:50:22,549 --> 00:50:19,370
the deployment motor back into its uh

1105
00:50:23,630 --> 00:50:22,559
operational state it was uh taken out of

1106
00:50:25,190 --> 00:50:23,640
operational state to do a

1107
00:50:27,049 --> 00:50:25,200
reconfiguration

1108
00:50:30,470 --> 00:50:27,059
and now it's ready to do the full move

1109
00:50:32,089 --> 00:50:30,480
once this this is done

1110
00:50:33,530 --> 00:50:32,099
we're coming to you live from Space

1111
00:50:34,849 --> 00:50:33,540
Telescope Science Institute in Baltimore

1112
00:50:37,069 --> 00:50:34,859
Maryland

1113
00:50:40,970 --> 00:50:37,079
this is happening in real time uh the

1114
00:50:50,270 --> 00:50:40,980
James Webb Space Telescope commissioning

1115
00:51:09,829 --> 00:50:51,770
you're looking at live coverage from the

1116
00:51:13,970 --> 00:51:11,930
command to deploy the wing is imminent

1117
00:51:15,770 --> 00:51:13,980
we're waiting for it any minute now and

1118
00:51:18,049 --> 00:51:15,780
then we will uh we'll watch on the uh

1119
00:51:19,790 --> 00:51:18,059
The Observatory visualization tool

1120
00:51:21,109 --> 00:51:19,800
to see that it'll just be a couple of

1121
00:51:22,970 --> 00:51:21,119
minutes something like four to five

1122
00:51:24,650 --> 00:51:22,980
minutes and then after that we will come

1123
00:51:26,390 --> 00:51:24,660
back with more more commentary about the

1124
00:51:27,650 --> 00:51:26,400
observatory and we'll talk to some of

1125
00:51:29,030 --> 00:51:27,660
the people that are some of the science

1126
00:51:30,589 --> 00:51:29,040
leads as well about some of the

1127
00:51:33,950 --> 00:51:30,599
scientific questions this Observatory

1128
00:51:41,030 --> 00:51:36,109
they've just given the campaign probably

1129
00:51:41,040 --> 00:51:46,010
I think

1130
00:51:51,049 --> 00:51:48,309
they're reviewing the parameters

1131
00:51:57,230 --> 00:51:51,059
parameters what goods you are going to

1132
00:52:08,809 --> 00:51:59,270
and this will move the mirrors into

1133
00:52:13,250 --> 00:52:11,329
the screen to the right shows us our

1134
00:52:16,910 --> 00:52:13,260
ground station

1135
00:52:19,130 --> 00:52:16,920
and the motor status is moving

1136
00:52:30,470 --> 00:52:19,140
doesn't see the mirrors move in the

1137
00:52:35,870 --> 00:52:32,270
it will take about four minutes for them

1138
00:52:40,549 --> 00:52:37,910
and a reminder this is real live footage

1139
00:52:42,829 --> 00:52:40,559
the there's a three second time delay it

1140
00:52:46,250 --> 00:52:42,839
takes that long for light to travel at

1141
00:52:48,230 --> 00:52:46,260
186 000 miles per second

1142
00:52:55,490 --> 00:52:48,240
um the James Webb Space Telescope is now

1143
00:52:59,930 --> 00:52:58,609
I think you remember about this

1144
00:53:01,670 --> 00:52:59,940
go ahead

1145
00:53:04,069 --> 00:53:01,680
I was just going to say just remember

1146
00:53:06,349 --> 00:53:04,079
that this visualization is real this is

1147
00:53:08,150 --> 00:53:06,359
not pre-recorded it's based on actual

1148
00:53:12,290 --> 00:53:08,160
data coming to us from the telescope

1149
00:53:16,790 --> 00:53:14,030
and the important thing about the light

1150
00:53:18,890 --> 00:53:16,800
delay is not that the light takes that

1151
00:53:20,150 --> 00:53:18,900
long but the data which moves at the

1152
00:53:27,530 --> 00:53:20,160
speed of light

1153
00:53:33,109 --> 00:53:30,230
I know that was a question we had on

1154
00:53:36,710 --> 00:53:33,119
some of ourselves with the status we

1155
00:53:38,990 --> 00:53:36,720
have started our uh deployment into the

1156
00:53:44,150 --> 00:53:39,000
deployed hard stops and our current

1157
00:53:44,160 --> 00:53:50,809
Mount copy

1158
00:53:55,370 --> 00:53:52,910
that was another of our deployment

1159
00:53:56,870 --> 00:53:55,380
Engineers uh confirming that everything

1160
00:54:01,010 --> 00:53:56,880
looks good with our mission operations

1161
00:54:04,190 --> 00:54:03,049
it's exciting to actually see it moving

1162
00:54:05,630 --> 00:54:04,200
you know there it is on the

1163
00:54:07,609 --> 00:54:05,640
visualization tool it's getting closer

1164
00:54:11,510 --> 00:54:07,619
and closer

1165
00:54:19,430 --> 00:54:11,520
yep it's it's gonna be momentous when it

1166
00:54:23,870 --> 00:54:21,049
the first Wing was successfully deployed

1167
00:54:25,790 --> 00:54:23,880
yesterday and uh and now this is the the

1168
00:54:29,329 --> 00:54:25,800
final part the primary mirror being

1169
00:54:33,230 --> 00:54:31,490
Julie give us a sense of the scale uh

1170
00:54:35,390 --> 00:54:33,240
these mirror segments I mean I had the

1171
00:54:36,589 --> 00:54:35,400
honor of watching this being built a lot

1172
00:54:38,990 --> 00:54:36,599
of it at Goddard

1173
00:54:40,789 --> 00:54:39,000
um how big a cross for example is is one

1174
00:54:43,430 --> 00:54:40,799
of those hexagons

1175
00:54:47,510 --> 00:54:43,440
uh they're about a meter and a half

1176
00:54:49,849 --> 00:54:47,520
across uh from tip to tip uh the

1177
00:54:51,530 --> 00:54:49,859
the hexagons are quite large it's

1178
00:54:54,049 --> 00:54:51,540
amazing to actually be in the clean room

1179
00:54:56,089 --> 00:54:54,059
and look up to see the whole mirror

1180
00:54:59,030 --> 00:54:56,099
assembled towering above you there's no

1181
00:55:00,230 --> 00:54:59,040
amount of seeing it on photos that kind

1182
00:55:03,109 --> 00:55:00,240
of gives you the sense of actually

1183
00:55:04,430 --> 00:55:03,119
standing next to it in a playroom when

1184
00:55:07,549 --> 00:55:04,440
it was assembled

1185
00:55:10,609 --> 00:55:07,559
and as we talked about before and uh

1186
00:55:13,010 --> 00:55:10,619
once it's uh fully into position here

1187
00:55:14,630 --> 00:55:13,020
the final shape that our primary mirror

1188
00:55:20,410 --> 00:55:14,640
is going to be called a tri-contagon

1189
00:55:20,420 --> 00:55:25,609
and everything still looks really good

1190
00:55:25,619 --> 00:55:28,549
it's so full

1191
00:55:37,490 --> 00:55:32,089
will be concave you can sort of just see

1192
00:55:42,470 --> 00:55:40,250
they actually have simulated some some

1193
00:55:50,510 --> 00:55:42,480
stars and things in space that you can

1194
00:55:54,049 --> 00:55:52,549
also as the mirror comes forward and I'm

1195
00:55:55,970 --> 00:55:54,059
not sure that we can see it at this

1196
00:55:58,490 --> 00:55:55,980
angle but there's a thing called it's

1197
00:56:00,829 --> 00:55:58,500
called the bat wing and it's a it's a

1198
00:56:05,270 --> 00:56:00,839
shade that falls down behind the mirror

1199
00:56:08,510 --> 00:56:05,280
to help shade any light or heat that

1200
00:56:09,910 --> 00:56:08,520
might be coming up through the hole in

1201
00:56:13,490 --> 00:56:09,920
the sun shade

1202
00:56:15,770 --> 00:56:13,500
from keeping any of the back side of the

1203
00:56:18,170 --> 00:56:15,780
telescope warm there's one on each side

1204
00:56:23,289 --> 00:56:18,180
that comes down passively as the motor

1205
00:56:28,789 --> 00:56:26,210
the mirrors

1206
00:56:32,109 --> 00:56:28,799
are very small

1207
00:56:34,670 --> 00:56:32,119
I think it's on the order of severeign

1208
00:56:36,829 --> 00:56:34,680
Ops we have reached the end of

1209
00:56:38,569 --> 00:56:36,839
deployment and we are pre-loading into

1210
00:56:40,990 --> 00:56:38,579
the latch pads

1211
00:56:43,549 --> 00:56:41,000
all right

1212
00:56:46,930 --> 00:56:43,559
[Laughter]

1213
00:56:53,089 --> 00:56:46,940
you see people clapping yes

1214
00:56:57,470 --> 00:56:54,770
wow just look at that

1215
00:57:00,829 --> 00:56:57,480
the primary mirror is successfully

1216
00:57:02,870 --> 00:57:00,839
deployed this is a first we have made a

1217
00:57:04,730 --> 00:57:02,880
space Observatory that was the mirror

1218
00:57:06,890 --> 00:57:04,740
was so large that it had to be folded up

1219
00:57:09,490 --> 00:57:06,900
to fit inside the room I don't see at

1220
00:57:12,950 --> 00:57:09,500
this time we're ready to continue with

1221
00:57:14,750 --> 00:57:12,960
693.046 enable activate scs250

1222
00:57:17,530 --> 00:57:14,760
um 240 um

1223
00:57:20,870 --> 00:57:17,540
256.

1224
00:57:23,809 --> 00:57:20,880
I am back that command line looks good

1225
00:57:28,789 --> 00:57:23,819
your go to execute don't be that

1226
00:57:32,510 --> 00:57:30,770
I think you can hear the relief in our

1227
00:57:40,970 --> 00:57:32,520
deployment Ops and you're going to

1228
00:57:45,530 --> 00:57:43,670
I it's I have to say it I I just feel

1229
00:57:47,510 --> 00:57:45,540
this kind of glow you know in my in my

1230
00:57:50,150 --> 00:57:47,520
my chest right now just seeing that that

1231
00:57:52,849 --> 00:57:50,160
mirror all deployed all together

1232
00:57:54,829 --> 00:57:52,859
the um the size of a mirror allows us to

1233
00:57:57,109 --> 00:57:54,839
collect uh more light from fainter

1234
00:57:58,970 --> 00:57:57,119
objects and a lot of cases that means

1235
00:58:01,970 --> 00:57:58,980
farther away objects that light took

1236
00:58:03,770 --> 00:58:01,980
many billions of years to travel to us a

1237
00:58:06,470 --> 00:58:03,780
chance to see the universe as it was

1238
00:58:08,030 --> 00:58:06,480
perhaps uh only a couple hundred million

1239
00:58:10,549 --> 00:58:08,040
years after the start after the big bang

1240
00:58:13,069 --> 00:58:10,559
the sensitivity of this mirror will

1241
00:58:15,710 --> 00:58:13,079
allow that and uh and the size of the

1242
00:58:17,870 --> 00:58:15,720
mirror also gives us a clearer uh higher

1243
00:58:20,329 --> 00:58:17,880
resolution able to see more detail in

1244
00:58:22,069 --> 00:58:20,339
space than ever before so this was

1245
00:58:23,809 --> 00:58:22,079
something that absolutely had to happen

1246
00:58:26,089 --> 00:58:23,819
you know we had to I had to unfold this

1247
00:58:28,849 --> 00:58:26,099
mirror the secondary focusing mirror had

1248
00:58:30,589 --> 00:58:28,859
to come out and uh and then a little bit

1249
00:58:32,630 --> 00:58:30,599
more than a week ago the the amazing sun

1250
00:58:34,789 --> 00:58:32,640
shield and there it is in front of us

1251
00:58:37,490 --> 00:58:34,799
you're looking at this uh this animation

1252
00:58:39,470 --> 00:58:37,500
this is not a pre-made animation this is

1253
00:58:42,410 --> 00:58:39,480
based on actual data coming from the

1254
00:58:44,030 --> 00:58:42,420
telescope to us right now we are live at

1255
00:58:47,510 --> 00:58:44,040
the Space Telescope Science Institute

1256
00:58:50,150 --> 00:58:47,520
and uh we have successfully unfolded the

1257
00:58:52,250 --> 00:58:50,160
the last part of the primary mirror

1258
00:58:53,630 --> 00:58:52,260
after this there is are still more

1259
00:58:55,430 --> 00:58:53,640
commissioning acts to come very

1260
00:58:57,309 --> 00:58:55,440
important ones for uh example focusing

1261
00:59:01,670 --> 00:58:57,319
okay

1262
00:59:03,950 --> 00:59:01,680
56 is active in the delayed state

1263
00:59:06,950 --> 00:59:03,960
and I've confirmed with the depth read

1264
00:59:10,250 --> 00:59:06,960
they're ready to begin this three-door

1265
00:59:12,730 --> 00:59:10,260
um latch off stow and latch to say

1266
00:59:15,770 --> 00:59:12,740
so we're ready to continue with

1267
00:59:18,530 --> 00:59:15,780
693.048 move one of 20.

1268
00:59:20,690 --> 00:59:18,540
popular Sunday window

1269
00:59:31,370 --> 00:59:20,700
and that proc looks good you are going

1270
00:59:36,710 --> 00:59:33,829
uh go through a mouthful of description

1271
00:59:38,329 --> 00:59:36,720
there of what happens next uh there

1272
00:59:41,210 --> 00:59:38,339
there's a

1273
00:59:44,390 --> 00:59:41,220
a hook latch and it's basically really

1274
00:59:47,150 --> 00:59:44,400
that it looks like a a big latch like

1275
00:59:50,510 --> 00:59:47,160
you would hook possibly on a bathroom

1276
00:59:53,750 --> 00:59:50,520
door or a tie down if you were if you

1277
00:59:55,910 --> 00:59:53,760
had tie down straps to hold some some uh

1278
00:59:57,710 --> 00:59:55,920
some packaging onto the back of a

1279
00:59:59,990 --> 00:59:57,720
vehicle

1280
01:00:00,950 --> 01:00:00,000
um it's a it's a it's a it's actually a

1281
01:00:03,950 --> 01:00:00,960
hook

1282
01:00:06,589 --> 01:00:03,960
um and you heard her call it three-door

1283
01:00:08,630 --> 01:00:06,599
and what that means is um it's

1284
01:00:10,670 --> 01:00:08,640
essentially it has a couple of different

1285
01:00:13,849 --> 01:00:10,680
degrees of motion that it can do okay

1286
01:00:18,950 --> 01:00:13,859
and by for perimeter review

1287
01:00:23,270 --> 01:00:20,990
each of each of the latches are a little

1288
01:00:25,490 --> 01:00:23,280
different in in which degrees of freedom

1289
01:00:27,950 --> 01:00:25,500
that they can move in and so the three

1290
01:00:29,270 --> 01:00:27,960
doors can see the parameters look good

1291
01:00:30,849 --> 01:00:29,280
you're going to continue with the motor

1292
01:00:35,510 --> 01:00:30,859
move

1293
01:00:35,520 --> 01:00:41,390
it's one of the types that we have

1294
01:00:45,109 --> 01:00:43,309
this latching procedure will take a

1295
01:00:46,730 --> 01:00:45,119
couple of hours we will be here through

1296
01:00:49,549 --> 01:00:46,740
the entirety of it we will be able to

1297
01:00:52,010 --> 01:00:49,559
tell you when it is complete uh and uh

1298
01:00:53,569 --> 01:00:52,020
we may pause our commentary uh now and

1299
01:00:55,190 --> 01:00:53,579
again that we'll have different guests

1300
01:00:56,750 --> 01:00:55,200
talking about aspects of the engineering

1301
01:00:59,150 --> 01:00:56,760
and science of the James Webb Space

1302
01:01:00,650 --> 01:00:59,160
Telescope through the next few hours and

1303
01:01:02,510 --> 01:01:00,660
uh this uh this procedure will take

1304
01:01:03,950 --> 01:01:02,520
quite a while but can you tell us a

1305
01:01:05,630 --> 01:01:03,960
little bit more about the latching but

1306
01:01:07,789 --> 01:01:05,640
we're going to be uh we're just saying

1307
01:01:10,609 --> 01:01:07,799
in the next few hours Julie

1308
01:01:13,069 --> 01:01:10,619
sure uh there's there's actually several

1309
01:01:15,230 --> 01:01:13,079
latches uh the next one that you'll hear

1310
01:01:17,569 --> 01:01:15,240
her talk about will be one of the two

1311
01:01:18,589 --> 01:01:17,579
doors uh and there's

1312
01:01:21,650 --> 01:01:18,599
um

1313
01:01:24,650 --> 01:01:21,660
there's there's four in total I believe

1314
01:01:26,329 --> 01:01:24,660
and each of these will will come into

1315
01:01:28,130 --> 01:01:26,339
position and then they'll very slowly

1316
01:01:29,450 --> 01:01:28,140
they want to make sure that they don't

1317
01:01:33,470 --> 01:01:29,460
do something that's called like over

1318
01:01:36,470 --> 01:01:33,480
constrained uh and as uh anyone who

1319
01:01:39,650 --> 01:01:36,480
understands how a mechanism might move

1320
01:01:41,750 --> 01:01:39,660
you can you can easily kind of get

1321
01:01:44,750 --> 01:01:41,760
yourself jammed into a position if you

1322
01:01:46,430 --> 01:01:44,760
uh try to tighten one thing before

1323
01:01:48,950 --> 01:01:46,440
you're completely aligned with another

1324
01:01:51,170 --> 01:01:48,960
almost like when you change your tire

1325
01:01:53,210 --> 01:01:51,180
you want to kind of do that star pattern

1326
01:01:55,069 --> 01:01:53,220
to wiggle it into the just the right

1327
01:01:56,510 --> 01:01:55,079
position to make sure it's flat you

1328
01:01:58,670 --> 01:01:56,520
don't want to tighten one of those bolts

1329
01:02:00,230 --> 01:01:58,680
before you before you get the others

1330
01:02:01,789 --> 01:02:00,240
snug and you want to tighten them up in

1331
01:02:03,349 --> 01:02:01,799
a pattern so they'll do the same thing

1332
01:02:06,710 --> 01:02:03,359
with these latches they'll make sure

1333
01:02:08,510 --> 01:02:06,720
that that they're done in a very precise

1334
01:02:10,730 --> 01:02:08,520
order that the different degrees of

1335
01:02:12,529 --> 01:02:10,740
freedoms of each of the latches are

1336
01:02:15,890 --> 01:02:12,539
coming into play in the order that they

1337
01:02:19,309 --> 01:02:15,900
had planned to make sure that they uh

1338
01:02:22,069 --> 01:02:19,319
get that mirror latched in and locked

1339
01:02:24,589 --> 01:02:22,079
down in the absolute best position so

1340
01:02:27,529 --> 01:02:24,599
that those mirrors are in range for what

1341
01:02:29,990 --> 01:02:27,539
they need to do for actually defining

1342
01:02:31,910 --> 01:02:30,000
the surface of that mirror with the

1343
01:02:36,230 --> 01:02:31,920
actuators and motions that will come

1344
01:02:39,289 --> 01:02:37,789
well Julie thank you so much for being

1345
01:02:40,970 --> 01:02:39,299
with us for this procedure uh we're

1346
01:02:43,250 --> 01:02:40,980
going to come back to you later on as

1347
01:02:45,230 --> 01:02:43,260
this happens at the moment we are going

1348
01:02:46,930 --> 01:02:45,240
to uh have one of our expert guests come

1349
01:02:49,870 --> 01:02:46,940
up here

1350
01:02:53,329 --> 01:02:49,880
we are ready to continue with

1351
01:02:54,950 --> 01:02:53,339
693.049 three door latch to save move

1352
01:03:03,589 --> 01:02:54,960
two of 20.

1353
01:03:07,670 --> 01:03:06,349
thank you for having me to continue

1354
01:03:13,730 --> 01:03:07,680
okay we'll come back to you later

1355
01:03:16,549 --> 01:03:15,230
the uh the next person we're going to be

1356
01:03:18,410 --> 01:03:16,559
talking to is the associate

1357
01:03:20,569 --> 01:03:18,420
administrator for science at Nasa Dr

1358
01:03:22,970 --> 01:03:20,579
Thomas circlekin Thomas it is wonderful

1359
01:03:24,950 --> 01:03:22,980
to see you how are you feeling to tell

1360
01:03:27,950 --> 01:03:24,960
me about what you just observed

1361
01:03:29,450 --> 01:03:27,960
oh I'm emotional about it that what an

1362
01:03:31,190 --> 01:03:29,460
amazing Milestone received that

1363
01:03:33,710 --> 01:03:31,200
beautiful pattern out there in the sky

1364
01:03:36,049 --> 01:03:33,720
now almost complete of course it needs

1365
01:03:38,289 --> 01:03:36,059
to latch but what an amazing Milestone

1366
01:03:42,529 --> 01:03:38,299
just ahead of it

1367
01:03:45,289 --> 01:03:42,539
178 out of 178 of these uh you know

1368
01:03:48,289 --> 01:03:45,299
actuators that uh that had to fire the

1369
01:03:50,750 --> 01:03:48,299
right way uh I'm just so amazed and they

1370
01:03:52,910 --> 01:03:50,760
know about this team

1371
01:03:54,170 --> 01:03:52,920
so one of the things that I've just sort

1372
01:03:55,670 --> 01:03:54,180
of I I haven't seen you for a while

1373
01:03:58,309 --> 01:03:55,680
without a mask you know they have a

1374
01:04:00,049 --> 01:03:58,319
solid isolated rooms and uh you're

1375
01:04:01,670 --> 01:04:00,059
you're always clean-shaven you're a

1376
01:04:05,329 --> 01:04:01,680
little bit different today is is there

1377
01:04:07,789 --> 01:04:05,339
is there some story behind that you

1378
01:04:10,309 --> 01:04:07,799
notice right so you know basically what

1379
01:04:12,170 --> 01:04:10,319
happened is after we launched frankly I

1380
01:04:13,670 --> 01:04:12,180
basically said I told my wife I'm not

1381
01:04:15,829 --> 01:04:13,680
going to shave until this entire

1382
01:04:17,390 --> 01:04:15,839
telescope is fully uh deployed this is

1383
01:04:19,609 --> 01:04:17,400
like my favorite sports team when

1384
01:04:22,190 --> 01:04:19,619
they're in the playoffs right you have

1385
01:04:23,870 --> 01:04:22,200
to be sure that you fully support them

1386
01:04:26,630 --> 01:04:23,880
so that's what I'm doing here I can't

1387
01:04:28,100 --> 01:04:26,640
wait to shave uh Michelle my wife says

1388
01:04:31,270 --> 01:04:28,110
like are they done soon

1389
01:04:33,589 --> 01:04:31,280
[Laughter]

1390
01:04:34,789 --> 01:04:33,599
so I mean did that actually gives us a

1391
01:04:37,069 --> 01:04:34,799
chance to talk a bit about what's coming

1392
01:04:38,150 --> 01:04:37,079
out next so you know about how long do

1393
01:04:39,430 --> 01:04:38,160
you think it's going to be until you

1394
01:04:42,529 --> 01:04:39,440
shave

1395
01:04:44,690 --> 01:04:42,539
well I I fully expect assuming that

1396
01:04:46,970 --> 01:04:44,700
everything goes well uh today I fully

1397
01:04:48,650 --> 01:04:46,980
expect to shave today and and I just

1398
01:04:51,710 --> 01:04:48,660
want you to know a lot you know this

1399
01:04:53,930 --> 01:04:51,720
team is basically uh on track within a

1400
01:04:56,210 --> 01:04:53,940
half a day or so of the fastest uh

1401
01:04:58,250 --> 01:04:56,220
schedule that we had to outline frankly

1402
01:05:01,130 --> 01:04:58,260
I sat there today with some of the

1403
01:05:05,829 --> 01:05:01,140
managers and said if you ask somebody uh

1404
01:05:12,950 --> 01:05:08,150
what would you have said I said it's

1405
01:05:15,109 --> 01:05:12,960
massively optimistic unrealistic I I

1406
01:05:17,270 --> 01:05:15,119
think this team is just incredible you

1407
01:05:18,710 --> 01:05:17,280
know back to my sports analogy you know

1408
01:05:20,870 --> 01:05:18,720
we're seeing that the team on the

1409
01:05:23,510 --> 01:05:20,880
playing field and it's just an awesome

1410
01:05:25,910 --> 01:05:23,520
team and frankly kind of over and above

1411
01:05:27,890 --> 01:05:25,920
all expectations that anybody might have

1412
01:05:29,690 --> 01:05:27,900
had

1413
01:05:31,069 --> 01:05:29,700
you're talking about the team you know

1414
01:05:32,750 --> 01:05:31,079
and all coming together but then there

1415
01:05:34,789 --> 01:05:32,760
are also some tremendous challenges that

1416
01:05:35,870 --> 01:05:34,799
this team has faced and you know I know

1417
01:05:37,010 --> 01:05:35,880
that that's something that you've been

1418
01:05:38,870 --> 01:05:37,020
you've been there with the team for

1419
01:05:40,789 --> 01:05:38,880
quite a while now can you give us a

1420
01:05:42,589 --> 01:05:40,799
sense about I mean not only did we have

1421
01:05:45,109 --> 01:05:42,599
covid you know where we were all trying

1422
01:05:46,370 --> 01:05:45,119
to do this and uh be isolated and be

1423
01:05:47,750 --> 01:05:46,380
careful for each other's safety and all

1424
01:05:49,490 --> 01:05:47,760
that but there were there were all kinds

1425
01:05:50,990 --> 01:05:49,500
of other challenges I mean tell us about

1426
01:05:53,150 --> 01:05:51,000
some of the things that you know in your

1427
01:05:55,910 --> 01:05:53,160
years on this Mission you were like wow

1428
01:05:58,130 --> 01:05:55,920
I'm amazed they overcame that

1429
01:06:00,049 --> 01:05:58,140
look um I just want to tell you first

1430
01:06:02,569 --> 01:06:00,059
Michelle I'm I'm uh you know very

1431
01:06:04,430 --> 01:06:02,579
humbled to be part of this uh team right

1432
01:06:06,529 --> 01:06:04,440
now and I know so many others who are

1433
01:06:08,150 --> 01:06:06,539
part of this team for decades before I

1434
01:06:09,170 --> 01:06:08,160
even showed up I've only been part of

1435
01:06:12,529 --> 01:06:09,180
this team

1436
01:06:15,289 --> 01:06:12,539
for uh five years and I'm honored uh to

1437
01:06:16,910 --> 01:06:15,299
be part of the team uh yes uh we've had

1438
01:06:19,490 --> 01:06:16,920
a number of challenges you know if you

1439
01:06:21,890 --> 01:06:19,500
uh of course look at everything that you

1440
01:06:24,230 --> 01:06:21,900
know go backwards uh anything with the

1441
01:06:26,150 --> 01:06:24,240
deployments uh uh some of the challenges

1442
01:06:28,490 --> 01:06:26,160
frankly that the team immediately uh

1443
01:06:30,190 --> 01:06:28,500
addressed uh they made it look easy even

1444
01:06:33,650 --> 01:06:30,200
though some of these challenges frankly

1445
01:06:36,170 --> 01:06:33,660
were tough uh you go back in time

1446
01:06:39,349 --> 01:06:36,180
and of course it's very hard to think

1447
01:06:41,329 --> 01:06:39,359
about uh the grit of this team that that

1448
01:06:44,450 --> 01:06:41,339
we're seeing without thinking of covet

1449
01:06:47,210 --> 01:06:44,460
right I mean uh what's really amazing uh

1450
01:06:49,370 --> 01:06:47,220
uh is how they overcame that right how

1451
01:06:51,770 --> 01:06:49,380
they did not you know they took every

1452
01:06:54,529 --> 01:06:51,780
excuse they could to stay on track right

1453
01:06:57,170 --> 01:06:54,539
that's it so often uh Michelle you know

1454
01:06:59,630 --> 01:06:57,180
uh we sometimes we see teams you know in

1455
01:07:01,309 --> 01:06:59,640
our private lives or even uh you know uh

1456
01:07:03,950 --> 01:07:01,319
elsewhere where where all of a sudden

1457
01:07:06,289 --> 01:07:03,960
you know people take excuses to do not

1458
01:07:09,710 --> 01:07:06,299
fulfill our goals this team found every

1459
01:07:12,529 --> 01:07:09,720
excuse to do so you go back in time and

1460
01:07:15,650 --> 01:07:12,539
you realize you know how hard it is to

1461
01:07:18,109 --> 01:07:15,660
be truly a single team and Michelle it's

1462
01:07:21,289 --> 01:07:18,119
not just the engineers it's our the good

1463
01:07:24,170 --> 01:07:21,299
people on uh on Capitol Hill who are uh

1464
01:07:26,510 --> 01:07:24,180
allocating the budgets uh uh the people

1465
01:07:28,849 --> 01:07:26,520
in the White House you know the all the

1466
01:07:30,650 --> 01:07:28,859
stakeholders there and I think what

1467
01:07:32,390 --> 01:07:30,660
correct Robinson and for me it's it's

1468
01:07:34,609 --> 01:07:32,400
just really important to say that name

1469
01:07:37,789 --> 01:07:34,619
on what he managed to do and kind of

1470
01:07:40,849 --> 01:07:37,799
overcame is really building a team from

1471
01:07:43,370 --> 01:07:40,859
the top all the way to the technician

1472
01:07:45,470 --> 01:07:43,380
the single team and of course that's why

1473
01:07:47,870 --> 01:07:45,480
that's why it's going so well right

1474
01:07:49,670 --> 01:07:47,880
because of you know unified teams you

1475
01:07:51,549 --> 01:07:49,680
know are a beautiful thing to watch and

1476
01:07:55,130 --> 01:07:51,559
yeah

1477
01:07:57,470 --> 01:07:55,140
for a couple minutes and into our move

1478
01:07:59,510 --> 01:07:57,480
to the safe position on the three-door

1479
01:08:02,390 --> 01:07:59,520
latch everything looks really good

1480
01:08:04,130 --> 01:08:02,400
strains are low and the strain offset

1481
01:08:06,470 --> 01:08:04,140
came in right where we wanted it so

1482
01:08:08,089 --> 01:08:06,480
we're looking good

1483
01:08:12,349 --> 01:08:08,099
mom copies that's awesome definitely

1484
01:08:16,010 --> 01:08:13,849
so as the associate administrator for

1485
01:08:18,050 --> 01:08:16,020
science at Nasa uh you know you are a

1486
01:08:20,390 --> 01:08:18,060
scientist and uh you know there's this

1487
01:08:21,950 --> 01:08:20,400
incredible scientific goals with this

1488
01:08:24,110 --> 01:08:21,960
Mission and like we said that this all

1489
01:08:25,550 --> 01:08:24,120
started from from questions you know we

1490
01:08:26,990 --> 01:08:25,560
launched the Hubble Space Telescope we

1491
01:08:29,149 --> 01:08:27,000
understood there was there was so many

1492
01:08:31,130 --> 01:08:29,159
more things to see even farther back in

1493
01:08:32,390 --> 01:08:31,140
time it could give me a sense about some

1494
01:08:34,309 --> 01:08:32,400
of the signs that you're most looking

1495
01:08:35,829 --> 01:08:34,319
forward to hoping that this Mission will

1496
01:08:38,269 --> 01:08:35,839
accomplish

1497
01:08:40,809 --> 01:08:38,279
how much time do you have Michelle right

1498
01:08:44,030 --> 01:08:40,819
I'm not gonna give you like a couple

1499
01:08:46,550 --> 01:08:44,040
but but you know I you know I've been

1500
01:08:48,349 --> 01:08:46,560
I've been doing a lot of reading and

1501
01:08:51,110 --> 01:08:48,359
thinking about this kind of early

1502
01:08:54,349 --> 01:08:51,120
universe and the galaxies and and for me

1503
01:08:57,289 --> 01:08:54,359
you know the the impact potential impact

1504
01:08:59,510 --> 01:08:57,299
of prime more Geo black holes uh in this

1505
01:09:02,149 --> 01:08:59,520
whole discussion really the relationship

1506
01:09:05,030 --> 01:09:02,159
of galaxies and black holes that are so

1507
01:09:06,709 --> 01:09:05,040
tight uh as we look at today's uh

1508
01:09:08,870 --> 01:09:06,719
galaxies kind of in our neighborhood

1509
01:09:11,090 --> 01:09:08,880
like how did that go there for me it

1510
01:09:13,490 --> 01:09:11,100
just boggles my mind you know to think

1511
01:09:15,289 --> 01:09:13,500
of these enormous structures in the

1512
01:09:17,209 --> 01:09:15,299
universe that are in the past I'm going

1513
01:09:18,590 --> 01:09:17,219
to give you a second example I'm

1514
01:09:19,370 --> 01:09:18,600
Michelle and you know of course it's

1515
01:09:21,769 --> 01:09:19,380
about

1516
01:09:24,769 --> 01:09:21,779
finding life elsewhere but I'm going to

1517
01:09:26,570 --> 01:09:24,779
focus on our own solar system we're

1518
01:09:28,910 --> 01:09:26,580
going to take observations make

1519
01:09:30,950 --> 01:09:28,920
observations for example of Europa you

1520
01:09:33,530 --> 01:09:30,960
know we did that with Hubble and there's

1521
01:09:35,149 --> 01:09:33,540
amazing papers out there from in nature

1522
01:09:38,329 --> 01:09:35,159
and science that says hey just

1523
01:09:41,570 --> 01:09:38,339
marginally we can see kind of emissions

1524
01:09:43,910 --> 01:09:41,580
of Europa that kind of are similar to

1525
01:09:46,849 --> 01:09:43,920
Enceladus for example where you know

1526
01:09:50,149 --> 01:09:46,859
water from these subsurface oceans are

1527
01:09:51,829 --> 01:09:50,159
coming out together with uh Organics uh

1528
01:09:53,149 --> 01:09:51,839
at then sellers the question is does

1529
01:09:53,990 --> 01:09:53,159
that happen with Europe and of course

1530
01:09:56,450 --> 01:09:54,000
we're

1531
01:10:00,649 --> 01:09:56,460
moving towards a launch of Clipper and

1532
01:10:02,689 --> 01:10:00,659
24 and we wanna make sure that if there

1533
01:10:04,490 --> 01:10:02,699
are such uh you know emission points

1534
01:10:06,290 --> 01:10:04,500
that we know that because we want to

1535
01:10:09,290 --> 01:10:06,300
take the measurements with that amazing

1536
01:10:11,450 --> 01:10:09,300
Mass spectrometer on uh Clipper a

1537
01:10:13,310 --> 01:10:11,460
similar type of discussions on Mars

1538
01:10:16,250 --> 01:10:13,320
where of course we're in the middle of

1539
01:10:18,050 --> 01:10:16,260
another huge Adventure trying to get the

1540
01:10:21,110 --> 01:10:18,060
samples back in the first round trip to

1541
01:10:23,209 --> 01:10:21,120
another planet and and for me again uh

1542
01:10:26,030 --> 01:10:23,219
observations of the Martian atmosphere

1543
01:10:28,910 --> 01:10:26,040
its composition and its dust components

1544
01:10:31,010 --> 01:10:28,920
are just so critical

1545
01:10:32,930 --> 01:10:31,020
this is something that I I think that

1546
01:10:35,030 --> 01:10:32,940
you know I really enjoyed seeing your

1547
01:10:37,910 --> 01:10:35,040
leadership on in the last years is is no

1548
01:10:40,010 --> 01:10:37,920
Mission stands alone you know we we have

1549
01:10:42,050 --> 01:10:40,020
missions each one supports the other

1550
01:10:43,850 --> 01:10:42,060
that it's not just this Mission then

1551
01:10:45,350 --> 01:10:43,860
that one there's a strategy that

1552
01:10:47,570 --> 01:10:45,360
everything works together so like you

1553
01:10:48,890 --> 01:10:47,580
said for exploring the solar system you

1554
01:10:50,750 --> 01:10:48,900
have something like the web telescope

1555
01:10:53,450 --> 01:10:50,760
which from a distance can see things

1556
01:10:55,189 --> 01:10:53,460
like like Mars Europa places like Titan

1557
01:10:57,470 --> 01:10:55,199
but but then we have missions that are

1558
01:11:00,189 --> 01:10:57,480
uh are poised to go there and explore

1559
01:11:03,169 --> 01:11:00,199
closer up as well

1560
01:11:05,570 --> 01:11:03,179
oh I I strongly believe that right and

1561
01:11:08,870 --> 01:11:05,580
it was so beautiful about nature and so

1562
01:11:10,850 --> 01:11:08,880
be amazing about the science program we

1563
01:11:12,770 --> 01:11:10,860
have at Nasa is data connectedness

1564
01:11:14,750 --> 01:11:12,780
between the different questions that are

1565
01:11:17,630 --> 01:11:14,760
there and and I to me that has always

1566
01:11:20,050 --> 01:11:17,640
been one of the most exciting parts of

1567
01:11:22,729 --> 01:11:20,060
uh studying nature is to see

1568
01:11:25,010 --> 01:11:22,739
relationships that were not innately

1569
01:11:27,530 --> 01:11:25,020
recognized there and I think the more we

1570
01:11:29,689 --> 01:11:27,540
learn about nature and especially in

1571
01:11:31,850 --> 01:11:29,699
astrophysics the more we see some of

1572
01:11:34,010 --> 01:11:31,860
these connections right what you know I

1573
01:11:36,229 --> 01:11:34,020
I'm always saying I'll I read some

1574
01:11:38,270 --> 01:11:36,239
papers not as many as I would like to uh

1575
01:11:39,790 --> 01:11:38,280
Michelle but but nonetheless I read some

1576
01:11:42,950 --> 01:11:39,800
of the papers I realized that

1577
01:11:45,229 --> 01:11:42,960
atmospheric models of exoplanets so

1578
01:11:54,910 --> 01:11:45,239
often are done by our good people and

1579
01:11:54,920 --> 01:11:59,770
haven't changed significantly

1580
01:12:04,010 --> 01:12:02,149
thank you

1581
01:12:05,570 --> 01:12:04,020
listening to the uh listening to assist

1582
01:12:06,950 --> 01:12:05,580
commands from the mock making sure we we

1583
01:12:08,990 --> 01:12:06,960
stay up to date on them

1584
01:12:10,729 --> 01:12:09,000
but uh but but you know absolutely I

1585
01:12:12,649 --> 01:12:10,739
mean you you mentioned the first stars

1586
01:12:14,030 --> 01:12:12,659
and uh there's probably plenty of people

1587
01:12:15,770 --> 01:12:14,040
in the audience that that don't really

1588
01:12:17,330 --> 01:12:15,780
know your background as the scientists I

1589
01:12:19,189 --> 01:12:17,340
mean maybe a little sense about your

1590
01:12:22,430 --> 01:12:19,199
scientific expertise and how you came to

1591
01:12:25,550 --> 01:12:22,440
be associate administrator of NASA

1592
01:12:27,530 --> 01:12:25,560
well so I I studied astrophysics and you

1593
01:12:30,050 --> 01:12:27,540
know uh uh you know I was really

1594
01:12:31,850 --> 01:12:30,060
inspired by some of these uh missions

1595
01:12:33,590 --> 01:12:31,860
frankly I remember when I was eight

1596
01:12:35,330 --> 01:12:33,600
years old I got this book about the

1597
01:12:38,209 --> 01:12:35,340
Voyager missions and some of these

1598
01:12:40,370 --> 01:12:38,219
telescope that Nancy Grace Roman right

1599
01:12:43,310 --> 01:12:40,380
uh it really started imagining that was

1600
01:12:45,830 --> 01:12:43,320
in the 70s uh when I got this book and

1601
01:12:47,870 --> 01:12:45,840
that inspired me out of the Little

1602
01:12:49,850 --> 01:12:47,880
Mountain Village in Switzerland to be

1603
01:12:52,250 --> 01:12:49,860
where I am right now I'm an

1604
01:12:54,470 --> 01:12:52,260
astrophysicist but I mostly focused uh

1605
01:12:56,450 --> 01:12:54,480
my work about the Sun and kind of the

1606
01:12:58,729 --> 01:12:56,460
inner solar system so I know how to do

1607
01:13:00,470 --> 01:12:58,739
mass spectrometers and I've worked with

1608
01:13:02,570 --> 01:13:00,480
teams and you know what I fell in love

1609
01:13:05,390 --> 01:13:02,580
with Michelle is really the ability of

1610
01:13:08,209 --> 01:13:05,400
working with amazing teams uh when I see

1611
01:13:10,550 --> 01:13:08,219
a team whether it's in athletics uh you

1612
01:13:13,189 --> 01:13:10,560
know or whether I see it in this control

1613
01:13:14,990 --> 01:13:13,199
room right there uh team that is truly

1614
01:13:18,530 --> 01:13:15,000
operating at their highest capability

1615
01:13:20,689 --> 01:13:18,540
I'm so excited to see it it's the most

1616
01:13:22,310 --> 01:13:20,699
beautiful thing but I'm also gives me so

1617
01:13:24,649 --> 01:13:22,320
much hope of all these other things

1618
01:13:26,149 --> 01:13:24,659
things we can do so so when I look at

1619
01:13:28,070 --> 01:13:26,159
astrophysics of course I think of the

1620
01:13:29,689 --> 01:13:28,080
classes and so many of the things that I

1621
01:13:31,910 --> 01:13:29,699
learned in the late 90s that are no

1622
01:13:34,910 --> 01:13:31,920
longer true and that's what science is

1623
01:13:36,890 --> 01:13:34,920
about because we learn all the time and

1624
01:13:39,530 --> 01:13:36,900
can you imagine even in five years from

1625
01:13:41,270 --> 01:13:39,540
now how classes everywhere around the

1626
01:13:43,910 --> 01:13:41,280
world will be affected by this very

1627
01:13:46,370 --> 01:13:43,920
amazing Observatory that's being set up

1628
01:13:49,310 --> 01:13:47,930
yeah there's going to be some very very

1629
01:13:50,930 --> 01:13:49,320
profound things I mean you were talking

1630
01:13:53,810 --> 01:13:50,940
about looking at some of the first

1631
01:13:55,610 --> 01:13:53,820
galaxies to form and this of course is

1632
01:13:57,050 --> 01:13:55,620
one of the reasons why we have an

1633
01:13:58,729 --> 01:13:57,060
infrared telescope which is different

1634
01:14:00,890 --> 01:13:58,739
from Hubble which was largely an

1635
01:14:02,870 --> 01:14:00,900
invisible light infrared actually allows

1636
01:14:04,610 --> 01:14:02,880
us to see and to some extent farther

1637
01:14:05,930 --> 01:14:04,620
back in time farther away in the

1638
01:14:07,970 --> 01:14:05,940
universe where the expansion of the

1639
01:14:09,770 --> 01:14:07,980
universe has actually stretched out the

1640
01:14:11,630 --> 01:14:09,780
light from visible light into the

1641
01:14:13,070 --> 01:14:11,640
infrared wavelengths and you mentioned

1642
01:14:15,229 --> 01:14:13,080
this close relationship between black

1643
01:14:17,030 --> 01:14:15,239
holes and galaxies I mean a lot of our

1644
01:14:18,830 --> 01:14:17,040
viewers out there probably don't realize

1645
01:14:20,510 --> 01:14:18,840
that we are orbiting around a giant

1646
01:14:22,490 --> 01:14:20,520
black hole right now at about half a

1647
01:14:23,750 --> 01:14:22,500
million miles an hour uh the giant black

1648
01:14:25,610 --> 01:14:23,760
hole in the middle of the the center of

1649
01:14:27,169 --> 01:14:25,620
the Galaxy and there seems to be some

1650
01:14:29,149 --> 01:14:27,179
relationship between how galaxies form

1651
01:14:31,370 --> 01:14:29,159
and how black holes form but there's

1652
01:14:34,430 --> 01:14:31,380
there's a real mystery about these big

1653
01:14:36,830 --> 01:14:34,440
black holes that we see so far away and

1654
01:14:38,450 --> 01:14:36,840
therefore so so far back in time maybe

1655
01:14:39,770 --> 01:14:38,460
give us a little more sense about this

1656
01:14:42,470 --> 01:14:39,780
is one of the things that as an

1657
01:14:45,229 --> 01:14:42,480
astrophysicist we look at we say I don't

1658
01:14:47,570 --> 01:14:45,239
understand how that happened

1659
01:14:49,970 --> 01:14:47,580
right it's it's truly a chicken and egg

1660
01:14:52,189 --> 01:14:49,980
problem right kind of right now it seems

1661
01:14:54,229 --> 01:14:52,199
to be the case that black horse and

1662
01:14:56,990 --> 01:14:54,239
galaxies really coexist right it's

1663
01:14:58,729 --> 01:14:57,000
actually really hard to find a Galaxy in

1664
01:15:00,770 --> 01:14:58,739
which there's no black hole there it

1665
01:15:03,350 --> 01:15:00,780
really seems that it's a really

1666
01:15:06,290 --> 01:15:03,360
important part of uh of the galactic

1667
01:15:08,810 --> 01:15:06,300
Evolution but how does that start is uh

1668
01:15:11,149 --> 01:15:08,820
is the black hole first what is the role

1669
01:15:12,169 --> 01:15:11,159
of the black holes uh uh you know from

1670
01:15:14,390 --> 01:15:12,179
the beginning you talked about the

1671
01:15:16,790 --> 01:15:14,400
interconnectedness uh Michelle we're

1672
01:15:20,510 --> 01:15:16,800
right now setting up a small telescope

1673
01:15:23,090 --> 01:15:20,520
we launched a few uh weeks ago uh XP you

1674
01:15:26,209 --> 01:15:23,100
know at the polarimetry Explorer uh that

1675
01:15:28,130 --> 01:15:26,219
uh and that and hopefully next week uh

1676
01:15:30,950 --> 01:15:28,140
we'll be able to give kind of first

1677
01:15:33,050 --> 01:15:30,960
slide of that kind of X-ray observation

1678
01:15:35,510 --> 01:15:33,060
kind of again providing new insights

1679
01:15:37,370 --> 01:15:35,520
about some of these uh kind of more

1680
01:15:39,050 --> 01:15:37,380
recent black calls kind of really trying

1681
01:15:41,930 --> 01:15:39,060
to understand what the mechanisms really

1682
01:15:43,970 --> 01:15:41,940
are and that that in that in those black

1683
01:15:46,189 --> 01:15:43,980
holes but also uh the environment around

1684
01:15:47,990 --> 01:15:46,199
it for example the roles of magnetic

1685
01:15:51,169 --> 01:15:48,000
fields that are so critical in so many

1686
01:15:55,790 --> 01:15:53,750
I know for me one of the things is

1687
01:15:57,050 --> 01:15:55,800
looking at the universe in the case of

1688
01:15:59,990 --> 01:15:57,060
Hubble we've

1689
01:16:01,850 --> 01:16:00,000
we met holes that are are gigantic they

1690
01:16:03,830 --> 01:16:01,860
are millions of times the mass of the

1691
01:16:06,229 --> 01:16:03,840
Sun and we're seeing them at a time when

1692
01:16:08,630 --> 01:16:06,239
the universe was only say you know 500

1693
01:16:10,550 --> 01:16:08,640
million years old and black holes you

1694
01:16:13,550 --> 01:16:10,560
know we tend to think of as being formed

1695
01:16:14,870 --> 01:16:13,560
by stars that die but you know when you

1696
01:16:17,510 --> 01:16:14,880
think about the universe being that

1697
01:16:20,630 --> 01:16:17,520
young you know how did such a huge black

1698
01:16:22,790 --> 01:16:20,640
hole form that quickly and as a as an

1699
01:16:24,350 --> 01:16:22,800
astrophysicist myself that studies stars

1700
01:16:26,450 --> 01:16:24,360
one of the things that I'm hoping web

1701
01:16:27,890 --> 01:16:26,460
will shed some light on is the fact that

1702
01:16:30,110 --> 01:16:27,900
the very first stars in the universe

1703
01:16:32,149 --> 01:16:30,120
might have been quite different than the

1704
01:16:33,110 --> 01:16:32,159
Stars today and maybe maybe that's

1705
01:16:35,330 --> 01:16:33,120
something you can give us a little bit

1706
01:16:37,310 --> 01:16:35,340
of an idea why why would the first Stars

1707
01:16:39,890 --> 01:16:37,320
be that much different from the Stars we

1708
01:16:41,990 --> 01:16:39,900
see around us right now

1709
01:16:43,970 --> 01:16:42,000
I think it's a really great question and

1710
01:16:46,790 --> 01:16:43,980
I think it's one of the most amazing

1711
01:16:49,310 --> 01:16:46,800
parts of uh really talking about how we

1712
01:16:51,590 --> 01:16:49,320
relate to our universe and that is that

1713
01:16:53,870 --> 01:16:51,600
of course when the universe starts uh at

1714
01:16:57,110 --> 01:16:53,880
the beginning that Adam's that form

1715
01:16:59,270 --> 01:16:57,120
really are much less rich in terms of

1716
01:17:02,510 --> 01:16:59,280
diversity than we have today you know on

1717
01:17:05,209 --> 01:17:02,520
my hands I have gold and platinum uh

1718
01:17:07,490 --> 01:17:05,219
rings that my wife gave me and uh we

1719
01:17:09,229 --> 01:17:07,500
know that those are not from the

1720
01:17:11,930 --> 01:17:09,239
beginning of the universe frankly they

1721
01:17:14,330 --> 01:17:11,940
come from neutron stars that are merging

1722
01:17:16,370 --> 01:17:14,340
that are much much later kind of after a

1723
01:17:18,590 --> 01:17:16,380
lifetime of a star so so when you look

1724
01:17:20,510 --> 01:17:18,600
at the first Stars you know like what

1725
01:17:24,470 --> 01:17:20,520
you have kind of the material you build

1726
01:17:26,630 --> 01:17:24,480
with is much lighter than stars that are

1727
01:17:29,510 --> 01:17:26,640
kind of that most of the stars that were

1728
01:17:31,850 --> 01:17:29,520
looking at night through a telescope

1729
01:17:34,430 --> 01:17:31,860
because those stars are Next Generation

1730
01:17:36,890 --> 01:17:34,440
stars in so many of the cases with much

1731
01:17:38,330 --> 01:17:36,900
heavier components that are there so the

1732
01:17:40,430 --> 01:17:38,340
question really is how do you build

1733
01:17:42,050 --> 01:17:40,440
those first stars and and for frankly

1734
01:17:43,729 --> 01:17:42,060
how do they then kick off that

1735
01:17:46,370 --> 01:17:43,739
evolutionary process there's a lot of

1736
01:17:47,990 --> 01:17:46,380
models and the data will of course

1737
01:17:50,030 --> 01:17:48,000
constrain these models that's what we

1738
01:17:52,250 --> 01:17:50,040
call learning right kind of it's say

1739
01:17:54,050 --> 01:17:52,260
this model is correct this model is not

1740
01:17:56,030 --> 01:17:54,060
correct and by the way there's some an

1741
01:17:58,310 --> 01:17:56,040
observation that none of the models

1742
01:18:00,050 --> 01:17:58,320
predicts which is the element of

1743
01:18:01,910 --> 01:18:00,060
surprise we can always bet on the

1744
01:18:03,890 --> 01:18:01,920
element of surprise Michelle frankly

1745
01:18:05,990 --> 01:18:03,900
often the surprising parts are the most

1746
01:18:07,729 --> 01:18:06,000
important ones

1747
01:18:09,410 --> 01:18:07,739
I sort of like that we're talking about

1748
01:18:11,090 --> 01:18:09,420
the history of chemical elements but in

1749
01:18:13,910 --> 01:18:11,100
there is always the element of surprise

1750
01:18:16,610 --> 01:18:13,920
yes the um you know the universe began

1751
01:18:18,290 --> 01:18:16,620
you know with hydrogen and helium you

1752
01:18:19,970 --> 01:18:18,300
know a tiny tiny little bit of a couple

1753
01:18:21,410 --> 01:18:19,980
other elements but as you mentioned

1754
01:18:22,970 --> 01:18:21,420
everything that really makes us up

1755
01:18:25,430 --> 01:18:22,980
things that make up a human body like

1756
01:18:27,110 --> 01:18:25,440
carbon or the calcium in our teeth or or

1757
01:18:30,050 --> 01:18:27,120
phosphorus or sulfur of the things that

1758
01:18:32,870 --> 01:18:30,060
we need for a DNA we have completed this

1759
01:18:34,610 --> 01:18:32,880
move of the three-door latch to save

1760
01:18:40,750 --> 01:18:34,620
so we're going to proceed with the

1761
01:18:45,590 --> 01:18:43,010
one of the things

1762
01:18:47,810 --> 01:18:45,600
hoping that the James Webb Observatory

1763
01:18:50,330 --> 01:18:47,820
will shed some light on is what the

1764
01:18:52,310 --> 01:18:50,340
universe was like before most of that

1765
01:18:54,350 --> 01:18:52,320
formed I mean really the origins of the

1766
01:18:56,030 --> 01:18:54,360
stuff that we are coming from but

1767
01:19:00,130 --> 01:18:56,040
there's another part of our origin too

1768
01:19:04,070 --> 01:19:00,140
you mentioned you know in five years

1769
01:19:06,290 --> 01:19:04,080
though that is the motor move 3 of 20

1770
01:19:07,610 --> 01:19:06,300
the command line looks good you're going

1771
01:19:13,070 --> 01:19:07,620
to execute

1772
01:19:20,810 --> 01:19:15,410
and you're going to continue I hope you

1773
01:19:24,709 --> 01:19:22,430
one of the things that I'm really

1774
01:19:26,570 --> 01:19:24,719
looking forward to is being able to uh

1775
01:19:29,270 --> 01:19:26,580
maybe in a few years from now point to a

1776
01:19:31,370 --> 01:19:29,280
star in this up in the sky and say that

1777
01:19:34,430 --> 01:19:31,380
there's a planet around that star that

1778
01:19:37,010 --> 01:19:34,440
has an environment similar to us here on

1779
01:19:38,990 --> 01:19:37,020
Earth maybe to take us through how how

1780
01:19:41,270 --> 01:19:39,000
will God do that how will I be able to

1781
01:19:43,430 --> 01:19:41,280
explore what the actual environments on

1782
01:19:46,669 --> 01:19:43,440
planets that far away around other stars

1783
01:19:49,310 --> 01:19:46,679
how will I be able to do that

1784
01:19:51,530 --> 01:19:49,320
so if you go back in time of the earth

1785
01:19:53,750 --> 01:19:51,540
of course long before we were here

1786
01:19:56,689 --> 01:19:53,760
uh the atmosphere of our planet was very

1787
01:19:57,790 --> 01:19:56,699
different and uh frankly the emergence

1788
01:20:00,110 --> 01:19:57,800
of Life

1789
01:20:03,410 --> 01:20:00,120
the atmosphere you can open that

1790
01:20:06,169 --> 01:20:03,420
Goldilocks song right now

1791
01:20:07,910 --> 01:20:06,179
the emergence of uh of life really

1792
01:20:09,830 --> 01:20:07,920
changed the atmosphere frankly there's a

1793
01:20:11,810 --> 01:20:09,840
number of uh papers out there that said

1794
01:20:14,209 --> 01:20:11,820
a large fraction of the nitrogen in our

1795
01:20:16,129 --> 01:20:14,219
atmosphere may very well be from the

1796
01:20:19,550 --> 01:20:16,139
emergence of life there's other of

1797
01:20:22,129 --> 01:20:19,560
course elements oxygen type of uh you

1798
01:20:24,410 --> 01:20:22,139
know ozone uh kind of elements like that

1799
01:20:27,350 --> 01:20:24,420
that really come of course are very much

1800
01:20:30,729 --> 01:20:27,360
part of that cycle of life that is here

1801
01:20:34,450 --> 01:20:30,739
so as we look at others monetary

1802
01:20:38,629 --> 01:20:34,460
what are the patterns there

1803
01:20:41,810 --> 01:20:38,639
are indicative of the presence both the

1804
01:20:44,149 --> 01:20:41,820
ability to have life there but even in

1805
01:20:46,729 --> 01:20:44,159
some cases kind of the the follow-up or

1806
01:20:48,709 --> 01:20:46,739
kind of the consistency with life uh

1807
01:20:50,689 --> 01:20:48,719
there is certainly from what we've

1808
01:20:53,570 --> 01:20:50,699
learned here but perhaps also other

1809
01:20:55,010 --> 01:20:53,580
versions that we yet have to

1810
01:20:57,530 --> 01:20:55,020
um well we have to learn of course

1811
01:20:59,810 --> 01:20:57,540
what's so hard about life is we have n

1812
01:21:02,450 --> 01:20:59,820
equals one we know only one life all

1813
01:21:04,430 --> 01:21:02,460
life on Earth is related and and you

1814
01:21:06,290 --> 01:21:04,440
know we learned a lot when went from one

1815
01:21:08,629 --> 01:21:06,300
solar system to many solar systems

1816
01:21:11,090 --> 01:21:08,639
Stellar systems you know frankly many of

1817
01:21:13,610 --> 01:21:11,100
the models crumbled within weeks of the

1818
01:21:17,090 --> 01:21:13,620
first observations that were published

1819
01:21:19,790 --> 01:21:17,100
in 1995 so when we look at life I'm sure

1820
01:21:23,330 --> 01:21:19,800
similar things will happen but for me

1821
01:21:26,629 --> 01:21:25,010
well that's absolutely wonderful so so

1822
01:21:28,490 --> 01:21:26,639
once again we're speaking to Dr Thomas

1823
01:21:30,290 --> 01:21:28,500
rebukin he's the associate administrator

1824
01:21:32,030 --> 01:21:30,300
for science at Nasa

1825
01:21:33,890 --> 01:21:32,040
um Thomas and our audience out there

1826
01:21:35,270 --> 01:21:33,900
we're going to take a short break we're

1827
01:21:37,370 --> 01:21:35,280
going to take a pause in the commentary

1828
01:21:39,590 --> 01:21:37,380
and we will be coming back at 11 o'clock

1829
01:21:41,450 --> 01:21:39,600
in the morning Eastern Standard Time to

1830
01:21:43,370 --> 01:21:41,460
resume our commentary but Thomas thank

1831
01:21:45,350 --> 01:21:43,380
you so much for joining us what an

1832
01:21:48,470 --> 01:21:45,360

so I'll wave to you from down in the

1837
01:21:57,590 --> 01:21:55,199

01:22:03,770 --> 01:22:01,500
Michelle it's just been wonderful I've

1841
01:22:05,750 --> 01:22:03,780
watched you many times uh from different

1842
01:22:07,610 --> 01:22:05,760
locations I know you have exactly the

1843
01:22:09,290 --> 01:22:07,620
same passion I do about this amazing

1844
01:22:12,169 --> 01:22:09,300
science and you can't wait to get those

1845
01:22:13,669 --> 01:22:12,179
data back in just a few months time

1846
01:22:15,050 --> 01:22:13,679
absolutely

1847
01:22:16,430 --> 01:22:15,060
thank you so much for joining us and

1848
01:22:18,350 --> 01:22:16,440
we'll be back in our commentary just a

1849
01:22:22,930 --> 01:22:18,360
few minutes

1850
01:22:22,940 --> 01:22:36,830
yeah yeah

1851
01:22:40,610 --> 01:22:38,689
okay and I would see that motor move

1852
01:22:42,010 --> 01:22:40,620
completed successfully we're ready to

1853
01:22:45,470 --> 01:22:42,020
continue with

1854
01:22:48,890 --> 01:22:45,480
693.052 it's the door latch to safe mode

1855
01:22:52,610 --> 01:22:50,450
it's not just on the win

1856
01:22:54,770 --> 01:22:52,620
and that command line looks good you're

1857
01:22:57,350 --> 01:22:54,780
going to execute

1858
01:23:00,290 --> 01:22:57,360
okay excuse me go ahead and Mr good

1859
01:23:43,550 --> 01:23:02,750
and you're going to continue hope we go

1860
01:23:47,629 --> 01:23:45,770
and stand by while we review the

1861
01:23:57,790 --> 01:23:47,639
parameters

1862
01:23:57,800 --> 01:24:46,430
go to continue with the move to continue

1863
01:24:51,350 --> 01:24:48,709
and I see the mirror movies in progress

1864
01:24:53,990 --> 01:24:51,360
this will take about 14 minutes

1865
01:27:34,910 --> 01:24:54,000
coffee for two minutes well let's stand

1866
01:27:38,629 --> 01:27:37,370
for the depth lead on Ops with the

1867
01:27:42,470 --> 01:27:38,639
status

1868
01:27:45,590 --> 01:27:42,480
um we are on step four of 20 of latching

1869
01:27:47,990 --> 01:27:45,600
we're latching the two-door to the safe

1870
01:27:48,890 --> 01:27:48,000
position uh into it a couple of minutes

1871
01:27:51,470 --> 01:27:48,900
now

1872
01:27:55,490 --> 01:27:51,480
again strains look really good nice and

1873
01:28:01,070 --> 01:27:55,500
low and our strain offset is uh matched

1874
01:28:01,080 --> 01:31:33,530
excellent mom copies thank you

1875
01:31:38,390 --> 01:31:35,930
this is definitely done Ops we are

1876
01:31:41,270 --> 01:31:38,400
halfway through this uh latching to the

1877
01:31:46,430 --> 01:31:41,280
safe position on the two-door and

1878
01:31:46,440 --> 01:31:56,209
welcome back to our live commentary

1879
01:31:59,810 --> 01:31:57,950
if you're joining us right now you're

1880
01:32:01,129 --> 01:31:59,820
looking at live coverage of the

1881
01:32:03,290 --> 01:32:01,139
commissioning of the James Webb Space

1882
01:32:04,910 --> 01:32:03,300
Telescope I'm here at the Space

1883
01:32:05,930 --> 01:32:04,920
Telescope Science Institute in Baltimore

1884
01:32:07,850 --> 01:32:05,940
Maryland

1885
01:32:10,729 --> 01:32:07,860
and what you're seeing on the screen

1886
01:32:13,010 --> 01:32:10,739
above me is a live live footage from the

1887
01:32:14,870 --> 01:32:13,020
mock Mission operations center for the

1888
01:32:17,810 --> 01:32:14,880
James Webb Space Telescope and then to

1889
01:32:20,810 --> 01:32:17,820
my left is an observatory visualization

1890
01:32:22,970 --> 01:32:20,820
tool which is showing you real-time data

1891
01:32:25,129 --> 01:32:22,980
Telemetry as they say from the James

1892
01:32:27,229 --> 01:32:25,139
Webb Space Telescope which is now over

1893
01:32:29,750 --> 01:32:27,239
600 000 miles away from us on its way

1894
01:32:32,570 --> 01:32:29,760
out to uh and orbit about A Million

1895
01:32:33,350 --> 01:32:32,580
Miles Away past the moon L2 the LaGrange

1896
01:32:35,689 --> 01:32:33,360
point

1897
01:32:38,990 --> 01:32:35,699
and just a few minutes ago we

1898
01:32:41,209 --> 01:32:39,000
successfully deployed the uh the final

1899
01:32:43,910 --> 01:32:41,219
part of the primary mirror the side Wing

1900
01:32:46,729 --> 01:32:43,920
So this has been a a wonderful morning

1901
01:32:49,370 --> 01:32:46,739
so far here in Baltimore we still have a

1902
01:33:21,590 --> 01:32:49,380
few hours oh as they latch this primary

1903
01:38:08,930 --> 01:33:53,870
foreign

1904
01:38:13,729 --> 01:38:11,090
so there's a step lead on Ops with the

1905
01:38:17,209 --> 01:38:13,739
status we've just completed the two-door

1906
01:38:20,270 --> 01:38:17,219
move to Safe position uh so now we're in

1907
01:38:26,870 --> 01:38:20,280
a position to stop the deployment motor

1908
01:38:26,880 --> 01:38:34,729
possible

1909
01:38:39,470 --> 01:38:37,790
let's see there's the step up sign up so

1910
01:38:41,870 --> 01:38:39,480
um per depth lead that murder myth

1911
01:38:43,330 --> 01:38:41,880
completed successfully we are going to

1912
01:38:48,109 --> 01:38:43,340
continue at

1913
01:38:51,890 --> 01:38:48,119
693.054 to determinate scf-256

1914
01:38:56,270 --> 01:38:53,510
that command line looks good you're

1915
01:38:57,350 --> 01:38:56,280
going to execute poppy you see how

1916
01:39:03,830 --> 01:38:57,360
devoted

1917
01:39:10,070 --> 01:39:05,750
you're going to terminate

1918
01:39:53,330 --> 01:39:11,810
you have to go

1919
01:39:57,709 --> 01:39:56,149
is complete

1920
01:40:00,169 --> 01:39:57,719
possible

1921
01:40:03,530 --> 01:40:00,179
and I see this with step UPS you are

1922
01:40:06,350 --> 01:40:03,540
going to disable scsid 256

1923
01:40:08,149 --> 01:40:06,360
that's 55. the command line looks good

1924
01:40:16,850 --> 01:40:08,159
you're going to execute

1925
01:40:20,810 --> 01:40:19,370
and you're going to disable so we go to

1926
01:40:45,050 --> 01:40:20,820
disable

1927
01:40:45,060 --> 01:40:49,570
rtcp is complete okay

1928
01:40:55,669 --> 01:40:53,270
k-n-o-c-u-r go to execute the deu stop

1929
01:40:57,229 --> 01:40:55,679
deploy at five six

1930
01:40:59,689 --> 01:40:57,239
that command line looks good you're

1931
01:41:03,950 --> 01:40:59,699
going to execute copy that do you see

1932
01:41:07,310 --> 01:41:05,689
and you're going to continue

1933
01:41:28,970 --> 01:41:07,320
hope you go to continue

1934
01:41:34,430 --> 01:41:31,550
rtcp is complete

1935
01:41:36,590 --> 01:41:34,440
you'll see devops can confirm that the

1936
01:41:39,649 --> 01:41:36,600
motor is stopped we're ready for two

1937
01:41:42,530 --> 01:41:39,659
nine six nine three zero five seven d EU

1938
01:41:45,770 --> 01:41:44,149
and the command line looks good you're

1939
01:41:52,070 --> 01:41:45,780
going to execute

1940
01:42:34,189 --> 01:41:53,870
you're gonna continue

1941
01:42:39,790 --> 01:42:36,709
the devops can confirm standby round

1942
01:42:45,970 --> 01:42:39,800
robin I see we're ready for step

1943
01:42:55,490 --> 01:42:48,530
and that proc looks good you're going to

1944
01:42:55,500 --> 01:43:20,990
is you're going to continue

1945
01:43:24,169 --> 01:43:22,910
the time we'll have some chance to uh to

1946
01:43:26,270 --> 01:43:24,179
recap some of the story of the James

1947
01:43:27,890 --> 01:43:26,280
Webb Space Telescope as well as talk to

1948
01:43:30,109 --> 01:43:27,900
some of the expert scientists engineers

1949
01:43:31,970 --> 01:43:30,119
that are working on that so if you're

1950
01:43:34,010 --> 01:43:31,980
just joining us you can also talk to us

1951
01:43:37,010 --> 01:43:34,020
on social media we ask that you use the

1952
01:43:38,750 --> 01:43:37,020
hashtag unfold the universe so hashtag

1953
01:43:41,570 --> 01:43:38,760
unfold the universe and we'll get to as

1954
01:43:43,609 --> 01:43:41,580
many as those questions as possible

1955
01:43:45,709 --> 01:43:43,619
so this has really been a momentous day

1956
01:43:47,689 --> 01:43:45,719
everybody is very happy with how things

1957
01:43:49,129 --> 01:43:47,699
have proceeded I think that it's a

1958
01:43:51,169 --> 01:43:49,139
really nice chance to kind of go back

1959
01:43:52,609 --> 01:43:51,179
and talk a bit about the larger story of

1960
01:43:54,649 --> 01:43:52,619
how the James Webb spells Space

1961
01:43:57,290 --> 01:43:54,659
Telescope got to where it is today over

1962
01:43:59,270 --> 01:43:57,300
600 000 miles out in space headed toward

1963
01:44:01,010 --> 01:43:59,280
a LaGrange point a balance between the

1964
01:44:03,350 --> 01:44:01,020
Sun and the Earth's gravity where it

1965
01:44:04,850 --> 01:44:03,360
will uh hopefully have many years ahead

1966
01:44:07,310 --> 01:44:04,860
of it observing the early universe

1967
01:44:09,830 --> 01:44:07,320
exoplanets and all things like that

1968
01:44:12,050 --> 01:44:09,840
so the uh that this telescope has

1969
01:44:15,050 --> 01:44:12,060
actually been uh in development for many

1970
01:44:17,030 --> 01:44:15,060
many years a lot of people say that 1995

1971
01:44:18,830 --> 01:44:17,040
was the time when it began when we

1972
01:44:20,570 --> 01:44:18,840
started planning for this Observatory

1973
01:44:22,669 --> 01:44:20,580
and what you're seeing now is some

1974
01:44:25,250 --> 01:44:22,679
footage of actually putting together the

1975
01:44:26,629 --> 01:44:25,260
primary mirror uh much of this work but

1976
01:44:28,430 --> 01:44:26,639
building the primary mirror and the

1977
01:44:30,109 --> 01:44:28,440
observatory and testing it was done at

1978
01:44:31,910 --> 01:44:30,119
Goddard space flight center these are

1979
01:44:33,649 --> 01:44:31,920
acoustic and vibration tests which were

1980
01:44:35,750 --> 01:44:33,659
necessary to make sure the telescope

1981
01:44:38,629 --> 01:44:35,760
could withstand the pressures of launch

1982
01:44:40,490 --> 01:44:38,639
so there's our acoustic test chamber and

1983
01:44:43,430 --> 01:44:40,500
you can see there there the telescope is

1984
01:44:45,590 --> 01:44:43,440
wrapped keep it clean this is a vacuum

1985
01:44:47,629 --> 01:44:45,600
test that was done at the Johnson Space

1986
01:44:49,790 --> 01:44:47,639
Center in Houston this is what we call

1987
01:44:52,370 --> 01:44:49,800
chamber a this is the largest vacuum

1988
01:44:54,530 --> 01:44:52,380
chamber that NASA has and this was made

1989
01:44:56,750 --> 01:44:54,540
during the Apollo era it was actually

1990
01:44:58,310 --> 01:44:56,760
large enough to fit full command modules

1991
01:45:01,010 --> 01:44:58,320
of the Apollo mission in there to test

1992
01:45:02,990 --> 01:45:01,020
so what you're seeing now on the screen

1993
01:45:04,310 --> 01:45:03,000
in front of you right now is live

1994
01:45:06,229 --> 01:45:04,320
footage from the mock the vision

1995
01:45:08,450 --> 01:45:06,239
operations center that's right above me

1996
01:45:10,910 --> 01:45:08,460
as I'm speaking to you and to the left

1997
01:45:13,129 --> 01:45:10,920
is our Observatory visualization tool

1998
01:45:15,470 --> 01:45:13,139
this is a computer-generated image but

1999
01:45:16,669 --> 01:45:15,480
this is a live image generated by data

2000
01:45:19,070 --> 01:45:16,679
that's actually coming from the

2001
01:45:21,470 --> 01:45:19,080
telescope as we speak so what happened

2002
01:45:23,629 --> 01:45:21,480
just a few minutes ago was the the

2003
01:45:27,050 --> 01:45:23,639
starboard side of the primary mirror the

2004
01:45:28,550 --> 01:45:27,060
mirror Wing was released into place and

2005
01:45:31,010 --> 01:45:28,560
uh and that's an incredible

2006
01:45:34,490 --> 01:45:31,020
accomplishment the the mirror is now

2007
01:45:39,550 --> 01:45:34,500
fully unable and uh that's uh for all of

2008
01:45:46,609 --> 01:45:41,990
incredible Joy Joy command line Looks

2009
01:45:49,850 --> 01:45:48,350
you'll hear me pause as I listen to

2010
01:45:51,109 --> 01:45:49,860
what's happening in the control room uh

2011
01:45:57,410 --> 01:45:51,119
they are just making sure that all the

2012
01:46:00,709 --> 01:45:59,149
and as I mentioned this procedure will

2013
01:46:02,570 --> 01:46:00,719
go on for a couple more hours we will

2014
01:46:03,830 --> 01:46:02,580
stay with it through the entire thing so

2015
01:46:05,330 --> 01:46:03,840
that at the end we'll be able to tell

2016
01:46:08,030 --> 01:46:05,340
you that the mirror has been safely

2017
01:46:09,590 --> 01:46:08,040
latched into its final position and that

2018
01:46:11,209 --> 01:46:09,600
will Mark the end of some major

2019
01:46:13,070 --> 01:46:11,219
commissioning efforts of the James Webb

2020
01:46:16,250 --> 01:46:13,080
Space Telescope there is more to come

2021
01:46:17,990 --> 01:46:16,260
this is not the last phase after this we

2022
01:46:19,970 --> 01:46:18,000
will be focusing the primary mirror

2023
01:46:21,410 --> 01:46:19,980
which is made of 18 independent segments

2024
01:46:23,030 --> 01:46:21,420
and then there will be Again Begin

2025
01:46:23,930 --> 01:46:23,040
commissioning of the science instruments

2026
01:46:26,450 --> 01:46:23,940
as well

2027
01:46:28,129 --> 01:46:26,460
so I think right now it's also a chance

2028
01:46:29,629 --> 01:46:28,139
to sort of talk about the journey that

2029
01:46:32,149 --> 01:46:29,639
Webb has been on

2030
01:46:33,890 --> 01:46:32,159
um this is a portable clean room the web

2031
01:46:36,649 --> 01:46:33,900
telescope of course had to be kept under

2032
01:46:39,590 --> 01:46:36,659
very very clean circumstances and that

2033
01:46:40,970 --> 01:46:39,600
left California on a special ship that

2034
01:46:43,250 --> 01:46:40,980
is actually designed to take a lot of

2035
01:46:45,649 --> 01:46:43,260
these uh specialized space spacecraft

2036
01:46:47,870 --> 01:46:45,659
cargo to the launch sites that the

2037
01:46:49,550 --> 01:46:47,880
European Space Agency runs in Peru

2038
01:46:51,410 --> 01:46:49,560
French Guiana this is in South America

2039
01:46:52,609 --> 01:46:51,420
and here you're seeing footage of that

2040
01:46:55,550 --> 01:46:52,619
portable clean room with the web

2041
01:46:58,430 --> 01:46:55,560
Observatory inside uh being taken off

2042
01:47:00,109 --> 01:46:58,440
the ship and being loaded onto the the

2043
01:47:02,450 --> 01:47:00,119
place where it will go up on an area in

2044
01:47:04,850 --> 01:47:02,460
five rocket so that's part of the

2045
01:47:06,530 --> 01:47:04,860
Journey of web and here you see uh

2046
01:47:08,510 --> 01:47:06,540
actually uh opening up that portable

2047
01:47:10,850 --> 01:47:08,520
clean room web is in its stowed

2048
01:47:12,290 --> 01:47:10,860
configuration folded up this is one of

2049
01:47:14,810 --> 01:47:12,300
the reasons it's been so exciting the

2050
01:47:15,950 --> 01:47:14,820
last couple of days this Observatory for

2051
01:47:18,169 --> 01:47:15,960
the first time we've launched an

2052
01:47:20,870 --> 01:47:18,179
observatory that was so big the mirror

2053
01:47:22,729 --> 01:47:20,880
had to be folded up and uh as people

2054
01:47:24,229 --> 01:47:22,739
often compared it to origami folding the

2055
01:47:26,870 --> 01:47:24,239
physical scope so it could fit inside

2056
01:47:41,330 --> 01:47:26,880
the fairing of the uh of the Ariane 5

2057
01:47:49,450 --> 01:47:45,530
and oh see you are going to continue to

2058
01:47:49,460 --> 01:47:55,010
is possible

2059
01:48:02,510 --> 01:47:56,810
as they continue the latching procedure

2060
01:48:06,649 --> 01:48:04,729
uh this was a Christmas present for all

2061
01:48:07,910 --> 01:48:06,659
of us this was about 7 30 in the morning

2062
01:48:10,310 --> 01:48:07,920
Eastern Standard Time in the United

2063
01:48:13,070 --> 01:48:10,320
States and there you see the launch of

2064
01:48:15,530 --> 01:48:13,080
the Ariane 5 rocket it was an absolutely

2065
01:48:18,169 --> 01:48:15,540
perfect launch uh they were able to get

2066
01:48:19,970 --> 01:48:18,179
enough energy from the launch itself to

2067
01:48:21,649 --> 01:48:19,980
uh to save some of the fuel on the web

2068
01:48:22,310 --> 01:48:21,659
telescope which we hope will extend its

2069
01:48:24,590 --> 01:48:22,320
life

2070
01:48:26,209 --> 01:48:24,600
and here you see some of the uh the

2071
01:48:28,070 --> 01:48:26,219
people at admission control and French

2072
01:48:29,870 --> 01:48:28,080
Guiana cheering after the successful

2073
01:48:32,330 --> 01:48:29,880
launch and what you're looking at here

2074
01:48:34,070 --> 01:48:32,340
is an animation of the observatory going

2075
01:48:35,990 --> 01:48:34,080
away from the rocket this is not an

2076
01:48:38,090 --> 01:48:36,000
anime animation this one here is the

2077
01:48:39,590 --> 01:48:38,100
actual footage there was a a camera on

2078
01:48:42,830 --> 01:48:39,600
the rocket itself and here we see the

2079
01:48:45,290 --> 01:48:42,840
web telescope coming off the Ariane 5 uh

2080
01:48:47,810 --> 01:48:45,300
second stage on its way out to the

2081
01:48:49,310 --> 01:48:47,820
LaGrange boy L2 that's about a million

2082
01:48:51,590 --> 01:48:49,320
miles away from Earth it's on the other

2083
01:48:53,629 --> 01:48:51,600
side of the moon it's a wonderful

2084
01:48:55,129 --> 01:48:53,639
environment for an infrared telescope

2085
01:48:56,810 --> 01:48:55,139
that needs to be very cold

2086
01:48:58,430 --> 01:48:56,820
here you're actually seeing again this

2087
01:49:00,530 --> 01:48:58,440
is real footage from the camera you're

2088
01:49:03,410 --> 01:49:00,540
seeing that the solar uh the solar

2089
01:49:05,090 --> 01:49:03,420
panels unfold this was the very first of

2090
01:49:06,950 --> 01:49:05,100
the uh the actual unfoldings that had to

2091
01:49:09,290 --> 01:49:06,960
occur because now the telescope was able

2092
01:49:11,810 --> 01:49:09,300
to power itself up using uh using

2093
01:49:13,729 --> 01:49:11,820
radiation from the Sun and then after

2094
01:49:16,010 --> 01:49:13,739
that of course came the amazing oh

2095
01:49:18,229 --> 01:49:16,020
there's everybody celebrating uh people

2096
01:49:20,390 --> 01:49:18,239
of course put in huge amounts of time uh

2097
01:49:22,250 --> 01:49:20,400
they uh they were here over the holidays

2098
01:49:23,570 --> 01:49:22,260
uh all of us have been working uh

2099
01:49:25,669 --> 01:49:23,580
straight through Christmas and New

2100
01:49:26,990 --> 01:49:25,679
Year's of course it's been wonderfully

2101
01:49:29,270 --> 01:49:27,000
joyful but there are a lot of families

2102
01:49:31,070 --> 01:49:29,280
back at home that uh I'm sure missed us

2103
01:49:32,870 --> 01:49:31,080
as well uh here's the animation of some

2104
01:49:34,790 --> 01:49:32,880
of the major commissioning points that

2105
01:49:36,890 --> 01:49:34,800
we've actually accomplished so the uh

2106
01:49:38,930 --> 01:49:36,900
the the the solar array was unfurled and

2107
01:49:40,370 --> 01:49:38,940
also the antenna that allows the web to

2108
01:49:42,950 --> 01:49:40,380
communicate with the uh with the Earth

2109
01:49:45,770 --> 01:49:42,960
uh now you see the web moving up from

2110
01:49:49,910 --> 01:49:45,780
the sun shield which is now beginning to

2111
01:49:52,010 --> 01:49:49,920
unfold this is a five layer kept on sun

2112
01:49:54,109 --> 01:49:52,020
shield it's a material that's very much

2113
01:49:56,930 --> 01:49:54,119
like mylar it's a very thin very strong

2114
01:49:58,850 --> 01:49:56,940
material in this case it actually has

2115
01:50:01,370 --> 01:49:58,860
some silicon in it to make it more

2116
01:50:02,870 --> 01:50:01,380
reflective and also uh put together in

2117
01:50:04,550 --> 01:50:02,880
in small segments so that it's very

2118
01:50:06,290 --> 01:50:04,560
strong and can withstand any sort of

2119
01:50:08,089 --> 01:50:06,300
small impacts from micro meteorites

2120
01:50:09,229 --> 01:50:08,099
which we micrometeorites which we do

2121
01:50:12,350 --> 01:50:09,239
expect over the course of the mission

2122
01:50:14,810 --> 01:50:12,360
and now that incredible sun shield is

2123
01:50:17,870 --> 01:50:14,820
fully extended the secondary mirror came

2124
01:50:19,810 --> 01:50:17,880
out a few days ago yesterday we saw the

2125
01:50:22,070 --> 01:50:19,820
first of the Wings

2126
01:50:24,530 --> 01:50:22,080
and today we're just kind of leaving the

2127
01:50:26,510 --> 01:50:24,540
second part

2128
01:50:28,550 --> 01:50:26,520
so now that we've gone through a little

2129
01:50:30,709 --> 01:50:28,560
bit of an update as to uh what this

2130
01:50:32,990 --> 01:50:30,719
tremendous Journey that this Observatory

2131
01:50:35,149 --> 01:50:33,000
has been on it's my pleasure to talk to

2132
01:50:37,250 --> 01:50:35,159
me Feinberg who is one of the senior

2133
01:50:38,689 --> 01:50:37,260
Engineers on the web telescope and he's

2134
01:50:40,370 --> 01:50:38,699
going to talk to us a bit more about

2135
01:50:42,649 --> 01:50:40,380
some of these mirrors of some of the

2136
01:50:45,169 --> 01:50:42,659
technology in web so so for one thing

2137
01:50:47,030 --> 01:50:45,179
Lee wonderful to see you uh I uh we're

2138
01:50:48,609 --> 01:50:47,040
all isolated from each other so that we

2139
01:50:52,750 --> 01:50:48,619
can okay

2140
01:50:58,850 --> 01:50:56,149
Michelle we are ready to continue to

2141
01:51:02,990 --> 01:50:58,860
begin the three-door cup latch to

2142
01:51:09,129 --> 01:51:04,790
so as we said

2143
01:51:20,589 --> 01:51:11,209
in our conversation you'll probably

2144
01:51:23,270 --> 01:51:22,310
I'm sorry can you say that again

2145
01:51:24,950 --> 01:51:23,280
Michelle

2146
01:51:26,450 --> 01:51:24,960
where you're sitting can you hear those

2147
01:51:29,330 --> 01:51:26,460
calls from the mock

2148
01:51:31,910 --> 01:51:29,340
uh I can hear yeah I can hear them yes

2149
01:51:34,010 --> 01:51:31,920
okay right excellent

2150
01:51:35,930 --> 01:51:34,020
so for one thing you know but before we

2151
01:51:37,189 --> 01:51:35,940
we launch right into the technical to

2152
01:51:39,950 --> 01:51:37,199
tell me a bit about how you're feeling

2153
01:51:42,709 --> 01:51:39,960
right now we're human beings first

2154
01:51:44,149 --> 01:51:42,719
yeah well I feel I feel good

2155
01:51:45,530 --> 01:51:44,159
um you know I feel like the the

2156
01:51:47,810 --> 01:51:45,540
mechanical and the deployment teams

2157
01:51:49,729 --> 01:51:47,820
really have done a phenomenal job

2158
01:51:52,129 --> 01:51:49,739
um you know the the optical team

2159
01:51:54,410 --> 01:51:52,139
actually is just about to get started so

2160
01:51:56,930 --> 01:51:54,420
it's sort of a transition time

2161
01:51:58,430 --> 01:51:56,940
um but it but to see a full primary

2162
01:52:00,410 --> 01:51:58,440
mirror this is something we've really

2163
01:52:02,750 --> 01:52:00,420
been thinking about for a long time and

2164
01:52:05,330 --> 01:52:02,760
uh it's it's just a great it's a great

2165
01:52:07,609 --> 01:52:05,340
thing to to see and and to be ready to

2166
01:52:09,770 --> 01:52:07,619
start aligning those mirrors

2167
01:52:11,149 --> 01:52:09,780
absolutely well let's talk a bit about

2168
01:52:12,290 --> 01:52:11,159
those mirrors I mean that's uh that's

2169
01:52:14,390 --> 01:52:12,300
sort of the expertise that you bring

2170
01:52:16,129 --> 01:52:14,400
with us so to begin with

2171
01:52:17,570 --> 01:52:16,139
these are very different mirrors than

2172
01:52:19,310 --> 01:52:17,580
most people are used to in their in

2173
01:52:21,290 --> 01:52:19,320
their regular life and in in many many

2174
01:52:23,030 --> 01:52:21,300
ways obviously incredibly specialized

2175
01:52:24,950 --> 01:52:23,040
and tell us about some of the ways these

2176
01:52:26,750 --> 01:52:24,960
mirrors are are just completely unique

2177
01:52:29,450 --> 01:52:26,760
and very different

2178
01:52:31,250 --> 01:52:29,460
yeah well let me start by just saying

2179
01:52:32,930 --> 01:52:31,260
you know when we when we started this a

2180
01:52:34,250 --> 01:52:32,940
couple decades ago

2181
01:52:35,750 --> 01:52:34,260
um you know we knew from the very

2182
01:52:37,850 --> 01:52:35,760
beginning that one of the hardest parts

2183
01:52:40,010 --> 01:52:37,860
of of making the observatory was going

2184
01:52:41,149 --> 01:52:40,020
to be the nurse and in fact if you go

2185
01:52:43,970 --> 01:52:41,159
all the way back to the first project

2186
01:52:45,589 --> 01:52:43,980
manager Bernie Siri he used to have this

2187
01:52:47,149 --> 01:52:45,599
chart that would show that you know one

2188
01:52:49,070 --> 01:52:47,159
of the key goals was to make a mirror

2189
01:52:51,050 --> 01:52:49,080
that could be lighter than the Hubble

2190
01:52:53,390 --> 01:52:51,060
nerve by about 10 times per unit area

2191
01:52:54,890 --> 01:52:53,400
and it had to work at incredibly cold

2192
01:52:57,350 --> 01:52:54,900
temperatures minus 400 degrees

2193
01:52:59,390 --> 01:52:57,360
Fahrenheit and it had to have a quality

2194
01:53:01,310 --> 01:52:59,400
of the mirror that was approaching the

2195
01:53:03,470 --> 01:53:01,320
quality of like visible mirrors like the

2196
01:53:05,750 --> 01:53:03,480
Hubble Space Telescope kind of image

2197
01:53:07,129 --> 01:53:05,760
quality and so these were you know a set

2198
01:53:08,510 --> 01:53:07,139
of challenges that were extremely

2199
01:53:10,010 --> 01:53:08,520
difficult there were some people who

2200
01:53:12,589 --> 01:53:10,020
thought we couldn't even make mirrors

2201
01:53:15,589 --> 01:53:12,599
that were this light and this quality

2202
01:53:17,330 --> 01:53:15,599
um so so actually it was it was a pretty

2203
01:53:18,589 --> 01:53:17,340
um collaborative effort we actually

2204
01:53:21,169 --> 01:53:18,599
worked with

2205
01:53:23,930 --> 01:53:21,179
um other other government agencies

2206
01:53:25,669 --> 01:53:23,940
including the Department of Defense it

2207
01:53:28,450 --> 01:53:25,679
was a collaboration to invest in

2208
01:53:31,729 --> 01:53:28,460
multiple different Technologies

2209
01:53:34,070 --> 01:53:31,739
one of which was actually a technology

2210
01:53:35,510 --> 01:53:34,080
in which the Mirror Has a bed of nails

2211
01:53:37,669 --> 01:53:35,520
under it a whole series of little tiny

2212
01:53:40,430 --> 01:53:37,679
actuators but one of them was a

2213
01:53:42,050 --> 01:53:40,440
brillianter and the beryllium that was

2214
01:53:43,910 --> 01:53:42,060
developed for web it was actually a new

2215
01:53:46,850 --> 01:53:43,920
form of beryllium it was they called it

2216
01:53:48,530 --> 01:53:46,860
an optical grade beryllium and it was it

2217
01:53:50,450 --> 01:53:48,540
was developed by a company it was called

2218
01:53:53,089 --> 01:53:50,460
brush Wellman that then later became a

2219
01:53:55,370 --> 01:53:53,099
Tyrion but this Optical grade brilliant

2220
01:53:56,689 --> 01:53:55,380
was supposed to be more uniform it was

2221
01:53:59,570 --> 01:53:56,699
going to have better properties for

2222
01:54:01,370 --> 01:53:59,580
being a telescope and um the key though

2223
01:54:04,129 --> 01:54:01,380
was could you build large mirrors that

2224
01:54:06,410 --> 01:54:04,139
are about almost 1.3 1.4 meters in

2225
01:54:07,910 --> 01:54:06,420
diameter these are segments

2226
01:54:08,990 --> 01:54:07,920
um that are incredibly lightweight so

2227
01:54:11,390 --> 01:54:09,000
you have to be able to machine the

2228
01:54:13,430 --> 01:54:11,400
mirrors from the back uh to lightweight

2229
01:54:16,010 --> 01:54:13,440
them and so it was really it was a

2230
01:54:18,709 --> 01:54:16,020
several year technology development

2231
01:54:21,350 --> 01:54:18,719
um it took it really took uh groups from

2232
01:54:23,810 --> 01:54:21,360
all over the United States the Machining

2233
01:54:25,970 --> 01:54:23,820
was done in Alabama and the polishing

2234
01:54:27,470 --> 01:54:25,980
was done in California and

2235
01:54:29,330 --> 01:54:27,480
um here actually you could see some of

2236
01:54:31,669 --> 01:54:29,340
the the beryllium billets that were made

2237
01:54:34,430 --> 01:54:31,679
in in Ohio

2238
01:54:36,890 --> 01:54:34,440
um so so so we developed the technology

2239
01:54:38,689 --> 01:54:36,900
and there was a mirror that was almost

2240
01:54:40,490 --> 01:54:38,699
the full size of what the ultimate

2241
01:54:43,189 --> 01:54:40,500
segments looked like that was we called

2242
01:54:44,570 --> 01:54:43,199
it a prototype mirror and here you could

2243
01:54:46,189 --> 01:54:44,580
see the light waiting of the of the

2244
01:54:48,530 --> 01:54:46,199
mirror from the back and and so that was

2245
01:54:50,030 --> 01:54:48,540
the first phase was just making a single

2246
01:54:52,609 --> 01:54:50,040
mirror that could meet our requirements

2247
01:54:55,250 --> 01:54:52,619
including a coating a gold coating that

2248
01:54:56,930 --> 01:54:55,260
would uh reflect the infrared light and

2249
01:54:59,030 --> 01:54:56,940
so um it was it was a large team effort

2250
01:55:02,149 --> 01:54:59,040
ball Aerospace and build Colorado kind

2251
01:55:03,410 --> 01:55:02,159
of LED that team and uh and that mirror

2252
01:55:07,250 --> 01:55:03,420
actually was competing with other

2253
01:55:08,629 --> 01:55:07,260
mirrors we had a very intense process by

2254
01:55:10,330 --> 01:55:08,639
which we selected which whatever

2255
01:55:12,709 --> 01:55:10,340
technology we would use but beryllium

2256
01:55:14,030 --> 01:55:12,719
won out because of its Superior

2257
01:55:14,930 --> 01:55:14,040
qualities at these very cold

2258
01:55:16,729 --> 01:55:14,940
temperatures

2259
01:55:18,470 --> 01:55:16,739
and that's really the key beryllium has

2260
01:55:20,330 --> 01:55:18,480
this amazing property that when you take

2261
01:55:22,669 --> 01:55:20,340
it to these very cold temperatures it's

2262
01:55:23,870 --> 01:55:22,679
incredibly stable there's there's a

2263
01:55:26,330 --> 01:55:23,880
there's a material property called

2264
01:55:28,850 --> 01:55:26,340
coefficient of thermal expansion and for

2265
01:55:30,709 --> 01:55:28,860
beryllium that material property is like

2266
01:55:32,629 --> 01:55:30,719
as perfect as could be at these very

2267
01:55:34,129 --> 01:55:32,639
cold temperatures and that really was

2268
01:55:36,050 --> 01:55:34,139
one of the key reasons we selected

2269
01:55:37,850 --> 01:55:36,060
brilliant along with the fact I mean one

2270
01:55:40,430 --> 01:55:37,860
of the big benefits is it's extremely

2271
01:55:41,689 --> 01:55:40,440
light and if you look at how large the

2272
01:55:43,850 --> 01:55:41,699
telescope is you know six and a half

2273
01:55:45,709 --> 01:55:43,860
meter diameter if we didn't make mirrors

2274
01:55:47,510 --> 01:55:45,719
this light we would not be able to lift

2275
01:55:49,910 --> 01:55:47,520
them with a rocket so it was it was a

2276
01:55:51,830 --> 01:55:49,920
long effort we then had to manufacture

2277
01:55:55,010 --> 01:55:51,840
the mirrors but but that's that's what

2278
01:55:57,109 --> 01:55:55,020
led to the mirrors have confirmed the

2279
01:55:58,550 --> 01:55:57,119
story actually goes you know even

2280
01:56:00,350 --> 01:55:58,560
farther back than that I mean so so

2281
01:56:02,290 --> 01:56:00,360
where was the beryllium mind I mean

2282
01:56:04,370 --> 01:56:02,300
you're saying this sort of a new type

2283
01:56:06,109 --> 01:56:04,380
where did it start where did the

2284
01:56:09,410 --> 01:56:06,119
brilliant come out of the ground

2285
01:56:12,830 --> 01:56:09,420
well so it's actually mined in Utah

2286
01:56:13,970 --> 01:56:12,840
um and and uh and you know it's mined in

2287
01:56:16,490 --> 01:56:13,980
sort of these

2288
01:56:19,070 --> 01:56:16,500
chunks and rocks that eventually will

2289
01:56:20,089 --> 01:56:19,080
get ground up and eventually made into a

2290
01:56:22,129 --> 01:56:20,099
powder form

2291
01:56:24,410 --> 01:56:22,139
and that was one of the things that they

2292
01:56:26,689 --> 01:56:24,420
were able to do was make a finer powder

2293
01:56:29,810 --> 01:56:26,699
a powder that has more spherical

2294
01:56:31,790 --> 01:56:29,820
qualities and um and then once you get

2295
01:56:34,370 --> 01:56:31,800
that powder and this was what brush

2296
01:56:36,530 --> 01:56:34,380
Wellman did in in Ohio just outside of

2297
01:56:38,209 --> 01:56:36,540
Cleveland once you get that powder you

2298
01:56:41,450 --> 01:56:38,219
can actually do a process that's called

2299
01:56:43,669 --> 01:56:41,460
hipping It's Hot isostatic pressure it's

2300
01:56:46,070 --> 01:56:43,679
a process that puts heat and pressure on

2301
01:56:48,350 --> 01:56:46,080
the beryllium and forms a Billet a

2302
01:56:50,270 --> 01:56:48,360
beryllium a block of beryllium that we

2303
01:56:53,209 --> 01:56:50,280
would slice like an Oreo cookie into two

2304
01:56:55,129 --> 01:56:53,219
mirror blanks and that's how we got sort

2305
01:56:57,890 --> 01:56:55,139
of the large blanks that would make up

2306
01:57:00,050 --> 01:56:57,900
what we would ultimately then machine

2307
01:57:03,350 --> 01:57:00,060
and so that so the first step was to go

2308
01:57:05,390 --> 01:57:03,360
from Utah to Ohio and then and then they

2309
01:57:07,669 --> 01:57:05,400
would be sent out to the uh Coleman

2310
01:57:08,810 --> 01:57:07,679
Alabama where the Machine Shop was that

2311
01:57:10,790 --> 01:57:08,820
would lightweight the mirror and they

2312
01:57:12,410 --> 01:57:10,800
would also put on the front surface they

2313
01:57:14,870 --> 01:57:12,420
would they would literally machine a

2314
01:57:17,209 --> 01:57:14,880
surface that was approximately the

2315
01:57:18,430 --> 01:57:17,219
surface we needed for each mirror

2316
01:57:20,750 --> 01:57:18,440
um but that was only the beginning

2317
01:57:22,609 --> 01:57:20,760
because the next phase was you had to

2318
01:57:23,750 --> 01:57:22,619
grind and polish the mirror and that you

2319
01:57:25,129 --> 01:57:23,760
know you know typically when you make a

2320
01:57:27,109 --> 01:57:25,139
mirror it's a polishing that's the

2321
01:57:29,330 --> 01:57:27,119
hardest part and actually the hardest

2322
01:57:31,790 --> 01:57:29,340
part of that process is testing the

2323
01:57:33,890 --> 01:57:31,800
mirror and one of the key things we had

2324
01:57:35,930 --> 01:57:33,900
to figure out was how do you test

2325
01:57:37,030 --> 01:57:35,940
mirrors that are inside of a cryogenic

2326
01:57:39,530 --> 01:57:37,040
chamber

2327
01:57:41,930 --> 01:57:39,540
the level that we needed and nobody had

2328
01:57:44,270 --> 01:57:41,940
done that before and we also needed to

2329
01:57:45,169 --> 01:57:44,280
make sure that all 18 mirrors matched

2330
01:57:47,390 --> 01:57:45,179
each other

2331
01:57:49,070 --> 01:57:47,400
so that you know if you make wonder and

2332
01:57:51,530 --> 01:57:49,080
then you made a second mirror and you

2333
01:57:52,910 --> 01:57:51,540
and you and you you align them relative

2334
01:57:54,830 --> 01:57:52,920
to each other they need to have the same

2335
01:57:56,149 --> 01:57:54,840
curvature and that actually turned out

2336
01:57:59,330 --> 01:57:56,159
to be one of the more difficult problems

2337
01:58:01,250 --> 01:57:59,340
so we had to develop uh methods you know

2338
01:58:03,709 --> 01:58:01,260
for testing mirrors and then for

2339
01:58:05,270 --> 01:58:03,719
polishing the mirrors when you when you

2340
01:58:06,709 --> 01:58:05,280
cool the mirror down at minus 400

2341
01:58:08,089 --> 01:58:06,719
degrees Fahrenheit it will literally

2342
01:58:10,490 --> 01:58:08,099
deform

2343
01:58:13,370 --> 01:58:10,500
um because things shrink but they shrink

2344
01:58:15,169 --> 01:58:13,380
in a way that's not perfect and so when

2345
01:58:16,790 --> 01:58:15,179
you when we made these mirrors what we

2346
01:58:18,649 --> 01:58:16,800
did is we would put them inside of a

2347
01:58:20,330 --> 01:58:18,659
chamber that would cool them down we

2348
01:58:22,910 --> 01:58:20,340
would test them with devices that are

2349
01:58:24,890 --> 01:58:22,920
outside of the chamber and once we know

2350
01:58:27,530 --> 01:58:24,900
how they deform we would warm the mirror

2351
01:58:29,089 --> 01:58:27,540
back up send it back to the place that

2352
01:58:31,490 --> 01:58:29,099
polished the mirror and we would polish

2353
01:58:34,729 --> 01:58:31,500
the inverse of the way they deformed

2354
01:58:35,689 --> 01:58:34,739
that process we call cryopolishing and

2355
01:58:37,729 --> 01:58:35,699
and here you can actually see the

2356
01:58:38,870 --> 01:58:37,739
mirrors going into the chamber this is

2357
01:58:40,609 --> 01:58:38,880
actually at the Marshall space flight

2358
01:58:43,250 --> 01:58:40,619
center it's a chamber that was used for

2359
01:58:45,649 --> 01:58:43,260
the X for the Chandra Space Telescope

2360
01:58:47,510 --> 01:58:45,659
was converted for testing these mirrors

2361
01:58:50,450 --> 01:58:47,520
we put a special liquid helium shroud

2362
01:58:52,729 --> 01:58:50,460
inside of it and we also developed new

2363
01:58:54,290 --> 01:58:52,739
test equipment that could work in the

2364
01:58:55,790 --> 01:58:54,300
presence of all the vibration that we

2365
01:58:58,850 --> 01:58:55,800
would get inside of a vacuum chamber so

2366
01:59:00,950 --> 01:58:58,860
so we did all that work we we polished

2367
01:59:03,410 --> 01:59:00,960
the mirrors with the inverse to deal

2368
01:59:04,550 --> 01:59:03,420
with these cool down effects and we also

2369
01:59:05,990 --> 01:59:04,560
had to deal with the fact that these

2370
01:59:07,970 --> 01:59:06,000
very lightweight mirrors to form under

2371
01:59:09,589 --> 01:59:07,980
Gravity you know right now is actually

2372
01:59:11,870 --> 01:59:09,599
the first time these mirrors have ever

2373
01:59:13,669 --> 01:59:11,880
been in microgravity but on the ground

2374
01:59:15,410 --> 01:59:13,679
there was always a gravity and literally

2375
01:59:17,450 --> 01:59:15,420
the mirrors are so light that the

2376
01:59:19,850 --> 01:59:17,460
gravity would deform the mirror so we

2377
01:59:21,350 --> 01:59:19,860
not only had to polish the them for the

2378
01:59:24,290 --> 01:59:21,360
cool down but we also had to polish them

2379
01:59:25,970 --> 01:59:24,300
for the effects of gravity and uh and

2380
01:59:27,589 --> 01:59:25,980
deal with the effects of gravity and so

2381
01:59:29,030 --> 01:59:27,599
we had to combine all that with the fact

2382
01:59:30,830 --> 01:59:29,040
that we had 18 mirrors that all had to

2383
01:59:32,810 --> 01:59:30,840
match each other so it was it was a

2384
01:59:35,030 --> 01:59:32,820
challenging process the whole the whole

2385
01:59:37,910 --> 01:59:35,040
effort from technology development to

2386
01:59:40,970 --> 01:59:37,920
manufacturing was about a decade from

2387
01:59:42,950 --> 01:59:40,980
about 2000 to 2010.

2388
01:59:44,750 --> 01:59:42,960
it's absolutely incredible and and what

2389
01:59:46,970 --> 01:59:44,760
you just said the whole idea is you get

2390
01:59:48,649 --> 01:59:46,980
these 18 mirrors and they all they all

2391
01:59:51,229 --> 01:59:48,659
have to work together as one single

2392
01:59:52,129 --> 01:59:51,239
mirror and and that's a big part of the

2393
01:59:53,810 --> 01:59:52,139
commissioning that's actually going to

2394
01:59:55,490 --> 01:59:53,820
be happening you know in a couple of you

2395
01:59:56,810 --> 01:59:55,500
know in the future now but let's talk

2396
01:59:58,850 --> 01:59:56,820
about some of those that there's

2397
02:00:01,010 --> 01:59:58,860
actuators on the back right that can

2398
02:00:03,890 --> 02:00:01,020
control each of these mirror segments

2399
02:00:05,750 --> 02:00:03,900
individually yeah you know it's funny

2400
02:00:07,430 --> 02:00:05,760
because a lot of people see pictures of

2401
02:00:10,189 --> 02:00:07,440
the web Space Telescope and they see the

2402
02:00:13,070 --> 02:00:10,199
front and it's gold and it looks amazing

2403
02:00:14,990 --> 02:00:13,080
but for an engineer uh it's really the

2404
02:00:17,390 --> 02:00:15,000
back of the mirror that is where all the

2405
02:00:19,550 --> 02:00:17,400
engineering goes in and in fact you know

2406
02:00:21,350 --> 02:00:19,560
maybe if we could freeze uh the picture

2407
02:00:22,729 --> 02:00:21,360
in about a second

2408
02:00:24,770 --> 02:00:22,739
um if you look at the back of the mirror

2409
02:00:26,149 --> 02:00:24,780
that's where all the engineering is the

2410
02:00:27,890 --> 02:00:26,159
you know the first part was the light

2411
02:00:29,750 --> 02:00:27,900
weighting and the rip structure and how

2412
02:00:32,750 --> 02:00:29,760
you do that so that the mirror is strong

2413
02:00:34,550 --> 02:00:32,760
enough to take to to launch but then you

2414
02:00:37,070 --> 02:00:34,560
also have to be able to to connect

2415
02:00:38,570 --> 02:00:37,080
actuators to the mirror and each primary

2416
02:00:41,330 --> 02:00:38,580
mirror segment actually has seven

2417
02:00:43,490 --> 02:00:41,340
different actuators there's there's

2418
02:00:46,550 --> 02:00:43,500
three pairs of actuators that you can

2419
02:00:49,070 --> 02:00:46,560
see in this video that are we call them

2420
02:00:52,370 --> 02:00:49,080
bipods that literally allow the mirror

2421
02:00:54,530 --> 02:00:52,380
to tip and tilt and move around in six

2422
02:00:56,330 --> 02:00:54,540
different degrees of freedom and then we

2423
02:00:58,550 --> 02:00:56,340
have also one actuator at the center of

2424
02:00:59,810 --> 02:00:58,560
the mirror which allows us to change the

2425
02:01:01,430 --> 02:00:59,820
curvature

2426
02:01:03,310 --> 02:01:01,440
and so each of the primary mirror

2427
02:01:06,589 --> 02:01:03,320
segments actually has seven actuators

2428
02:01:07,910 --> 02:01:06,599
and it wasn't obvious exactly how to

2429
02:01:10,490 --> 02:01:07,920
design those from the beginning in fact

2430
02:01:12,410 --> 02:01:10,500
the very first design only had three

2431
02:01:14,870 --> 02:01:12,420
actuators plus a central actuator so

2432
02:01:17,089 --> 02:01:14,880
four total and as time went on we

2433
02:01:18,709 --> 02:01:17,099
understood better you know how we needed

2434
02:01:20,510 --> 02:01:18,719
to move the mirrors in order to make a

2435
02:01:23,209 --> 02:01:20,520
perfect primary mirror over the full

2436
02:01:25,629 --> 02:01:23,219
primary and we also needed to understand

2437
02:01:27,970 --> 02:01:25,639
how to mount those actuators

2438
02:01:30,350 --> 02:01:27,980
the actuators themselves are actually

2439
02:01:31,790 --> 02:01:30,360
you know an amazing achievement

2440
02:01:34,070 --> 02:01:31,800
themselves they were they were designed

2441
02:01:35,990 --> 02:01:34,080
by ball Aerospace using these special

2442
02:01:39,169 --> 02:01:36,000
little gear Motors that can move the

2443
02:01:40,790 --> 02:01:39,179
mirrors in steps that are so small

2444
02:01:43,189 --> 02:01:40,800
they're just a fraction of a human hair

2445
02:01:46,010 --> 02:01:43,199
in fact the smallest step that we can

2446
02:01:48,229 --> 02:01:46,020
move is about 120 000 of a human hair

2447
02:01:50,330 --> 02:01:48,239
and that is so that we can move the

2448
02:01:53,270 --> 02:01:50,340
mirrors into position so that all 18

2449
02:01:55,310 --> 02:01:53,280
mirrors together are will be aligned to

2450
02:01:56,570 --> 02:01:55,320
less than a wavelength of light if you

2451
02:01:58,669 --> 02:01:56,580
were to kind of go across the whole

2452
02:02:00,950 --> 02:01:58,679
surface and so we needed an actuator

2453
02:02:02,930 --> 02:02:00,960
that could move in these tiny steps but

2454
02:02:05,689 --> 02:02:02,940
do it at minus 400 degrees Fahrenheit

2455
02:02:07,430 --> 02:02:05,699
and that's a lot of complexity and

2456
02:02:09,169 --> 02:02:07,440
challenges and then at the same time

2457
02:02:10,790 --> 02:02:09,179
these actuators have to survive launch

2458
02:02:12,109 --> 02:02:10,800
and they you know so they have to be

2459
02:02:15,350 --> 02:02:12,119
able to deal with you know vibrations

2460
02:02:17,030 --> 02:02:15,360
large vibrations and get the mirrors

2461
02:02:19,850 --> 02:02:17,040
into the right position initially

2462
02:02:21,310 --> 02:02:19,860
because when we launch the mirrors we

2463
02:02:23,810 --> 02:02:21,320
actually have them in a special position

2464
02:02:25,729 --> 02:02:23,820
that is designed for launching them

2465
02:02:27,109 --> 02:02:25,739
where the mirrors are up against we call

2466
02:02:30,709 --> 02:02:27,119
it a hard stop so they're in a nice

2467
02:02:32,270 --> 02:02:30,719
secure way secure position but actually

2468
02:02:34,870 --> 02:02:32,280
in the coming week we're going to deploy

2469
02:02:36,770 --> 02:02:34,880
the mirrors about a half inch forward

2470
02:02:38,870 --> 02:02:36,780
to this point where we can start

2471
02:02:40,609 --> 02:02:38,880
aligning them so these so these motors

2472
02:02:41,750 --> 02:02:40,619
had to be able to get you forward by

2473
02:02:43,609 --> 02:02:41,760
about a half an inch and then move in

2474
02:02:46,550 --> 02:02:43,619
these very small steps and so that's

2475
02:02:48,410 --> 02:02:46,560
there's a lot of different challenges it

2476
02:02:50,390 --> 02:02:48,420
took a huge team of people across the

2477
02:02:52,790 --> 02:02:50,400
country there's there's companies that

2478
02:02:54,589 --> 02:02:52,800
develop the motors and in Florida a

2479
02:02:57,169 --> 02:02:54,599
company that developed the bearings in

2480
02:02:58,430 --> 02:02:57,179
New Hampshire I mean all over you know

2481
02:03:00,350 --> 02:02:58,440
while web is an international

2482
02:03:02,570 --> 02:03:00,360
collaboration

2483
02:03:05,629 --> 02:03:02,580
the the telescope itself was actually

2484
02:03:07,970 --> 02:03:05,639
built within the United States but you

2485
02:03:10,310 --> 02:03:07,980
know maybe 20 or 30 States made major

2486
02:03:12,470 --> 02:03:10,320
contributions just to the primary mayor

2487
02:03:14,270 --> 02:03:12,480
itself that's how that's how significant

2488
02:03:16,070 --> 02:03:14,280
an effort it was and that's how much

2489
02:03:17,330 --> 02:03:16,080
coordination it took the team from

2490
02:03:20,450 --> 02:03:17,340
Northrop Grumman the team from ball

2491
02:03:22,310 --> 02:03:20,460
Aerospace uh the teams from L3 Harris

2492
02:03:23,629 --> 02:03:22,320
and ATK that all worked on this primary

2493
02:03:25,070 --> 02:03:23,639
mirror they had to work with all these

2494
02:03:27,550 --> 02:03:25,080
subcontractors from all over the United

2495
02:03:29,930 --> 02:03:27,560
States to make all these pieces

2496
02:03:31,370 --> 02:03:29,940
in fact I actually believe we have a map

2497
02:03:32,990 --> 02:03:31,380
that we could show the different

2498
02:03:35,390 --> 02:03:33,000
collaborators you know all over the

2499
02:03:36,350 --> 02:03:35,400
United States uh the primary mirror I

2500
02:03:37,970 --> 02:03:36,360
think they're gonna they're gonna run

2501
02:03:40,250 --> 02:03:37,980
that yes here we are

2502
02:03:42,890 --> 02:03:40,260
okay yeah

2503
02:03:45,530 --> 02:03:42,900
um yeah I mean it's it's literally you

2504
02:03:48,470 --> 02:03:45,540
know all over the country and obviously

2505
02:03:51,530 --> 02:03:48,480
the people who kind of worked on this

2506
02:03:53,810 --> 02:03:51,540
got a lot of frequent flyer mileage

2507
02:03:55,250 --> 02:03:53,820
um but yeah I mean it was it was a team

2508
02:03:56,990 --> 02:03:55,260
effort and we we had three different

2509
02:03:59,149 --> 02:03:57,000
NASA centers early in the program

2510
02:04:01,370 --> 02:03:59,159
working on this um you know I I come

2511
02:04:03,530 --> 02:04:01,380
from Goddard which was the lead for the

2512
02:04:05,390 --> 02:04:03,540
The Observatory and the telescope where

2513
02:04:06,649 --> 02:04:05,400
it was all integrated but we had uh the

2514
02:04:08,870 --> 02:04:06,659
folks from Marshall space flight center

2515
02:04:10,430 --> 02:04:08,880
who had a lot of uh you know who helped

2516
02:04:12,890 --> 02:04:10,440
us with the testing and the mirror

2517
02:04:14,390 --> 02:04:12,900
technology we had JPL involved in the in

2518
02:04:15,350 --> 02:04:14,400
the algorithms

2519
02:04:17,510 --> 02:04:15,360
um and then there was this large

2520
02:04:19,370 --> 02:04:17,520
contractor team led by Northrop Grumman

2521
02:04:21,410 --> 02:04:19,380
but with companies all over the country

2522
02:04:23,450 --> 02:04:21,420
and for the mirrors it really was ball

2523
02:04:26,209 --> 02:04:23,460
Aerospace that was the lead so it really

2524
02:04:27,770 --> 02:04:26,219
took a large collaborative effort and

2525
02:04:30,229 --> 02:04:27,780
one of the really neat things about it

2526
02:04:32,089 --> 02:04:30,239
was when you work on something like like

2527
02:04:34,910 --> 02:04:32,099
the James Webb Space Telescope that is

2528
02:04:37,010 --> 02:04:34,920
so incredible important capabilities

2529
02:04:38,689 --> 02:04:37,020
it's not hard to get people to want to

2530
02:04:40,970 --> 02:04:38,699
work on it you get you get the most

2531
02:04:42,890 --> 02:04:40,980
incredible people and they're so

2532
02:04:45,290 --> 02:04:42,900
dedicated because they know how exciting

2533
02:04:47,450 --> 02:04:45,300
it is and so and and they all you know

2534
02:04:49,129 --> 02:04:47,460
everyone worked really collaboratively I

2535
02:04:51,229 --> 02:04:49,139
know a lot of the folks who worked on

2536
02:04:53,930 --> 02:04:51,239
this you know from the people who were

2537
02:04:56,149 --> 02:04:53,940
you know ground the nerves people put

2538
02:04:57,910 --> 02:04:56,159
the motors together we know they're all

2539
02:04:59,990 --> 02:04:57,920
following you know a lot of them

2540
02:05:01,490 --> 02:05:00,000
a lot of them haven't even been on the

2541
02:05:03,290 --> 02:05:01,500
program for over 10 years but they're

2542
02:05:05,930 --> 02:05:03,300
following every little step in detail

2543
02:05:07,669 --> 02:05:05,940
with a lot of Pride and and I will tell

2544
02:05:09,530 --> 02:05:07,679
you that for you know you see a few

2545
02:05:12,169 --> 02:05:09,540
folks on television that you're watching

2546
02:05:13,250 --> 02:05:12,179
in the mission operations center but for

2547
02:05:16,609 --> 02:05:13,260
every one of those people there's

2548
02:05:18,229 --> 02:05:16,619
probably you know hundreds of people who

2549
02:05:20,089 --> 02:05:18,239
led up to that point who are all

2550
02:05:22,550 --> 02:05:20,099
watching with pride and that's what it

2551
02:05:25,189 --> 02:05:22,560
took to get to this point

2552
02:05:26,450 --> 02:05:25,199
yeah it's amazing I mean you talk about

2553
02:05:27,950 --> 02:05:26,460
every step of the way you know I

2554
02:05:30,350 --> 02:05:27,960
remember at one point uh they were

2555
02:05:32,810 --> 02:05:30,360
flying uh parts of the primary for

2556
02:05:35,270 --> 02:05:32,820
testing on the C5 which is a gigantic

2557
02:05:37,250 --> 02:05:35,280
aircraft that has this huge Hollow

2558
02:05:39,290 --> 02:05:37,260
interior that you can take very very

2559
02:05:40,910 --> 02:05:39,300
large objects and I got a chance to talk

2560
02:05:42,530 --> 02:05:40,920
to the flight crew and you know and and

2561
02:05:44,510 --> 02:05:42,540
these these young men who were actually

2562
02:05:46,490 --> 02:05:44,520
in charge of flying the airplane were so

2563
02:05:48,050 --> 02:05:46,500
excited to be flying the James Webb

2564
02:05:50,930 --> 02:05:48,060
Space Telescope they just thought that

2565
02:05:52,550 --> 02:05:50,940
was a wonderful thing to do so we talked

2566
02:05:54,229 --> 02:05:52,560
a bit about well we talked a bit about

2567
02:05:55,970 --> 02:05:54,239
about building and testing the primary

2568
02:05:57,770 --> 02:05:55,980
mirrors and then the idea that these

2569
02:06:00,169 --> 02:05:57,780
segments like you said that they have to

2570
02:06:01,609 --> 02:06:00,179
function in in zero gravity which is

2571
02:06:03,470 --> 02:06:01,619
something that you can't do on Earth you

2572
02:06:05,750 --> 02:06:03,480
need to make sure you you compensate for

2573
02:06:07,910 --> 02:06:05,760
that and also at the low temperature but

2574
02:06:09,649 --> 02:06:07,920
what comes next in commissioning is is

2575
02:06:11,629 --> 02:06:09,659
something pretty incredible and that is

2576
02:06:13,790 --> 02:06:11,639
getting all of these 18 segments to work

2577
02:06:15,229 --> 02:06:13,800
together and maybe you can step us

2578
02:06:17,330 --> 02:06:15,239
through a little bit about what you know

2579
02:06:18,709 --> 02:06:17,340
what comes next you know with a little

2580
02:06:20,270 --> 02:06:18,719
bit of a timeline and what we're going

2581
02:06:21,790 --> 02:06:20,280
to do to actually make this thing into

2582
02:06:24,890 --> 02:06:21,800
one big mirror

2583
02:06:27,109 --> 02:06:24,900
yeah well um so first of all in just a

2584
02:06:28,430 --> 02:06:27,119
few days we're going to start

2585
02:06:29,530 --> 02:06:28,440
um exercising all the little Motors

2586
02:06:33,709 --> 02:06:29,540
there's actually

2587
02:06:35,569 --> 02:06:33,719
132 we call them actuators total on the

2588
02:06:37,129 --> 02:06:35,579
telescope um there's seven on each of

2589
02:06:39,109 --> 02:06:37,139
the primary mirror segments and there's

2590
02:06:40,250 --> 02:06:39,119
six on the secondary mirror and so the

2591
02:06:42,530 --> 02:06:40,260
first thing we're going to do is what we

2592
02:06:43,910 --> 02:06:42,540
call mirror deployment that's a that's

2593
02:06:45,350 --> 02:06:43,920
about a week and a half to two week

2594
02:06:46,609 --> 02:06:45,360
operation

2595
02:06:48,709 --> 02:06:46,619
um so that'll be starting actually as

2596
02:06:50,629 --> 02:06:48,719
early as this Tuesday and that's just to

2597
02:06:52,729 --> 02:06:50,639
get the mirrors at a point where we can

2598
02:06:55,370 --> 02:06:52,739
start tipping and tilting them in order

2599
02:06:57,350 --> 02:06:55,380
to align them but um after that we'll

2600
02:06:59,089 --> 02:06:57,360
wait a little bit we wait about a week

2601
02:07:00,890 --> 02:06:59,099
are a little over a week for the

2602
02:07:02,750 --> 02:07:00,900
instruments to get cold enough so that

2603
02:07:04,490 --> 02:07:02,760
we can get images so so we can't

2604
02:07:06,649 --> 02:07:04,500
actually start we can't get first light

2605
02:07:08,270 --> 02:07:06,659
until the instruments are cold enough

2606
02:07:11,089 --> 02:07:08,280
this is one of the things about being an

2607
02:07:12,770 --> 02:07:11,099
infrared Observatory uh is you need very

2608
02:07:14,990 --> 02:07:12,780
cold detectors so we've got to wait for

2609
02:07:16,370 --> 02:07:15,000
the instruments to get cold but once

2610
02:07:17,990 --> 02:07:16,380
that happens the very first thing we're

2611
02:07:19,310 --> 02:07:18,000
going to do is we'll look at a bright

2612
02:07:27,470 --> 02:07:19,320
star

2613
02:07:29,149 --> 02:07:27,480
are really blurry okay and it's not

2614
02:07:33,910 --> 02:07:29,159
going to look real pretty

2615
02:07:39,229 --> 02:07:37,069
yeah yeah so you can see light will come

2616
02:07:41,030 --> 02:07:39,239
into the 18 mirrors and they'll they'll

2617
02:07:42,770 --> 02:07:41,040
behave like 18 separate telescopes

2618
02:07:44,209 --> 02:07:42,780
because they're not aligned yet so each

2619
02:07:46,370 --> 02:07:44,219
mirror actually forms a telescope

2620
02:07:48,229 --> 02:07:46,380
between the primary mirror segment and

2621
02:07:50,330 --> 02:07:48,239
the secondary mirror and that makes a

2622
02:07:52,069 --> 02:07:50,340
series of spots and one of the first

2623
02:07:54,410 --> 02:07:52,079
things we're going to do is find all 18

2624
02:07:56,030 --> 02:07:54,420
segments with those spots and then

2625
02:07:57,950 --> 02:07:56,040
ultimately what we need to do is get

2626
02:08:00,169 --> 02:07:57,960
those spots on top of each other so so

2627
02:08:02,270 --> 02:08:00,179
we'll align the spots we'll line those

2628
02:08:04,609 --> 02:08:02,280
primary mirror segments well enough that

2629
02:08:06,229 --> 02:08:04,619
we have nice spots that we can form on

2630
02:08:07,609 --> 02:08:06,239
top of each other we call that the

2631
02:08:09,649 --> 02:08:07,619
forming on top of each other image

2632
02:08:11,089 --> 02:08:09,659
stacking but it is a little bit of a

2633
02:08:13,010 --> 02:08:11,099
long process because we have to take

2634
02:08:15,290 --> 02:08:13,020
images we have to figure out how to move

2635
02:08:17,930 --> 02:08:15,300
the mirrors we actually have a special

2636
02:08:19,970 --> 02:08:17,940
wavefront room here at Space Telescope

2637
02:08:23,089 --> 02:08:19,980
Science Institute and we'll have it team

2638
02:08:24,410 --> 02:08:23,099
of real experts from Bull aerospace and

2639
02:08:26,270 --> 02:08:24,420
from Space Telescope Science Institute

2640
02:08:28,669 --> 02:08:26,280
from Goddard that all will work together

2641
02:08:30,830 --> 02:08:28,679
and they'll get the images they'll

2642
02:08:33,050 --> 02:08:30,840
analyze them using software that they've

2643
02:08:35,330 --> 02:08:33,060
rehearsed all of this with they've done

2644
02:08:37,609 --> 02:08:35,340
simulations of all this and we've tested

2645
02:08:39,410 --> 02:08:37,619
a lot of this with a testbed telescope

2646
02:08:42,050 --> 02:08:39,420
that was built up and they will go

2647
02:08:44,450 --> 02:08:42,060
through and they'll get those 18 images

2648
02:08:46,129 --> 02:08:44,460
on top of each other and at that point

2649
02:08:48,950 --> 02:08:46,139
we're ready to get into what we call

2650
02:08:51,410 --> 02:08:48,960
phasing and phasing is a little bit like

2651
02:08:52,850 --> 02:08:51,420
if you think of sort of oceans I'm sorry

2652
02:08:55,550 --> 02:08:52,860
if you think of waves in an ocean

2653
02:08:57,169 --> 02:08:55,560
imagine you have different Surfers and

2654
02:08:59,689 --> 02:08:57,179
they're each surfing on a different wave

2655
02:09:02,270 --> 02:08:59,699
what we need is for all of those Surfers

2656
02:09:04,129 --> 02:09:02,280
to be on the same wave and so we need

2657
02:09:07,189 --> 02:09:04,139
all of those mirrors to be essentially

2658
02:09:09,589 --> 02:09:07,199
on the same wave wave of light light

2659
02:09:11,510 --> 02:09:09,599
travels in electromagnetic waves and we

2660
02:09:13,550 --> 02:09:11,520
need them all to be on the same wave of

2661
02:09:15,589 --> 02:09:13,560
light otherwise we will get images that

2662
02:09:16,850 --> 02:09:15,599
are kind of confusing

2663
02:09:18,229 --> 02:09:16,860
um and so we'll go through a process

2664
02:09:21,229 --> 02:09:18,239
first we go through a process called

2665
02:09:23,209 --> 02:09:21,239
course phasing where we'll get

2666
02:09:25,310 --> 02:09:23,219
every you know all the waves all the

2667
02:09:27,530 --> 02:09:25,320
mirrors lined up to maybe one or two

2668
02:09:29,990 --> 02:09:27,540
waves so imagine the Surfers are almost

2669
02:09:31,850 --> 02:09:30,000
all in the same wave but not quite and

2670
02:09:34,030 --> 02:09:31,860
then we'll go through fine phasing and

2671
02:09:36,709 --> 02:09:34,040
fine phasing is the very final sequence

2672
02:09:38,030 --> 02:09:36,719
we actually use special algorithms that

2673
02:09:39,830 --> 02:09:38,040
were developed

2674
02:09:42,169 --> 02:09:39,840
primarily actually if you go all the way

2675
02:09:44,270 --> 02:09:42,179
back to when Hubble Space Telescope had

2676
02:09:46,250 --> 02:09:44,280
its blurry problem you know that the

2677
02:09:47,750 --> 02:09:46,260
sphere collaboration problem there were

2678
02:09:49,310 --> 02:09:47,760
algorithms that were developed to figure

2679
02:09:51,589 --> 02:09:49,320
out the prescription of Hubble so that

2680
02:09:54,229 --> 02:09:51,599
we could repair Hubble and those same

2681
02:09:56,089 --> 02:09:54,239
algorithms are actually being applied

2682
02:09:57,830 --> 02:09:56,099
here to align

2683
02:09:59,629 --> 02:09:57,840
the primary mirror in this very final

2684
02:10:01,609 --> 02:09:59,639
stage it's almost like you have a blurry

2685
02:10:03,530 --> 02:10:01,619
primary mirror and so we'll take images

2686
02:10:05,629 --> 02:10:03,540
in the main science camera the near

2687
02:10:06,830 --> 02:10:05,639
infrared camera but we'll take them

2688
02:10:08,510 --> 02:10:06,840
through Focus you know we'll take

2689
02:10:10,490 --> 02:10:08,520
different it's almost like you move the

2690
02:10:12,709 --> 02:10:10,500
focus on your camera so we'll take a

2691
02:10:14,270 --> 02:10:12,719
series of images and then we'll run them

2692
02:10:15,890 --> 02:10:14,280
through these special algorithms that

2693
02:10:17,390 --> 02:10:15,900
we've developed we've we started what

2694
02:10:19,430 --> 02:10:17,400
with what we did on how about we've

2695
02:10:21,229 --> 02:10:19,440
adapted them for the fact that this is a

2696
02:10:23,270 --> 02:10:21,239
segmented telescope but that's what's

2697
02:10:26,209 --> 02:10:23,280
going to allow us to align this mirror

2698
02:10:28,850 --> 02:10:26,219
perfectly and eventually we're going to

2699
02:10:30,109 --> 02:10:28,860
get an image of a single star so a star

2700
02:10:33,410 --> 02:10:30,119
will come in

2701
02:10:34,910 --> 02:10:33,420
very early on and maybe you know a

2702
02:10:37,010 --> 02:10:34,920
couple weeks three weeks or so it'll

2703
02:10:38,689 --> 02:10:37,020
look like 18 separate images but we

2704
02:10:41,689 --> 02:10:38,699
think by sometime in March we'll

2705
02:10:44,149 --> 02:10:41,699
actually have a star form a single image

2706
02:10:46,430 --> 02:10:44,159
and that's kind of the first goal

2707
02:10:47,810 --> 02:10:46,440
um of of the alignment process and then

2708
02:10:49,430 --> 02:10:47,820
from there really what we're doing is

2709
02:10:51,950 --> 02:10:49,440
we're aligning the secondary mirror to

2710
02:10:53,450 --> 02:10:51,960
give us uh image an image of a star that

2711
02:10:55,310 --> 02:10:53,460
works in all the four instruments you

2712
02:10:57,229 --> 02:10:55,320
know over the full field that takes

2713
02:10:59,030 --> 02:10:57,239
about another month and a month and a

2714
02:11:01,069 --> 02:10:59,040
half so that so the whole process is

2715
02:11:03,589 --> 02:11:01,079
about three and a half months we call it

2716
02:11:05,149 --> 02:11:03,599
wave front sensing and control but

2717
02:11:06,890 --> 02:11:05,159
really what it is is it's aligning all

2718
02:11:09,350 --> 02:11:06,900
these mirrors to act like a perfect

2719
02:11:11,510 --> 02:11:09,360
telescope and um and at the end of all

2720
02:11:13,430 --> 02:11:11,520
that we'll be able to hand off a

2721
02:11:15,109 --> 02:11:13,440
telescope some of the science instrument

2722
02:11:16,370 --> 02:11:15,119
teams who will be finishing up the

2723
02:11:18,290 --> 02:11:16,380
collaboration

2724
02:11:21,050 --> 02:11:18,300
um and then get on with some of the

2725
02:11:24,709 --> 02:11:22,850
well that's absolutely incredible and

2726
02:11:25,850 --> 02:11:24,719
that's probably a nice place for us to

2727
02:11:28,069 --> 02:11:25,860
break because we're going to bring on

2728
02:11:30,350 --> 02:11:28,079
one of those uh scientists that is

2729
02:11:32,450 --> 02:11:30,360
waiting to use uh web uh so again we're

2730
02:11:33,830 --> 02:11:32,460
talking to Lee Feinberg uh one of the

2731
02:11:35,569 --> 02:11:33,840
senior Engineers on the James Webb Space

2732
02:11:38,750 --> 02:11:35,579
Telescope it's such a pleasure to have

2733
02:11:41,030 --> 02:11:38,760
you here Lee congratulations thank you

2734
02:11:42,530 --> 02:11:41,040
and uh the rest of the day goes very

2735
02:11:45,530 --> 02:11:42,540
well for you

2736
02:11:47,330 --> 02:11:45,540
yeah thank you very much

2737
02:11:48,890 --> 02:11:47,340
so for those of you that are joining us

2738
02:11:50,149 --> 02:11:48,900
you're watching live coverage of the

2739
02:11:52,310 --> 02:11:50,159
commissioning of the James Webb Space

2740
02:11:53,930 --> 02:11:52,320
Telescope we are all here at the Space

2741
02:11:56,689 --> 02:11:53,940
Telescope Science Institute in Baltimore

2742
02:11:58,790 --> 02:11:56,699
Maryland and I'm Michelle Fowler I'm

2743
02:12:00,050 --> 02:11:58,800
from Goddard space flight center and if

2744
02:12:01,490 --> 02:12:00,060
you'd like to join us later on we'll

2745
02:12:03,250 --> 02:12:01,500
probably have some time for social media

2746
02:12:05,330 --> 02:12:03,260
questions so you can use the hashtag

2747
02:12:08,270 --> 02:12:05,340
unfold the universe so once again

2748
02:12:09,770 --> 02:12:08,280
hashtag unfold the universe and that

2749
02:12:11,350 --> 02:12:09,780
will allow us to to see your questions

2750
02:12:13,430 --> 02:12:11,360
and answers

2751
02:12:16,189 --> 02:12:13,440
so the next person that I'm going to

2752
02:12:17,930 --> 02:12:16,199
talk to is Dr Antonella Nota and

2753
02:12:19,609 --> 02:12:17,940
Antonella works here at the Space

2754
02:12:21,169 --> 02:12:19,619
Telescope Science Institute she's the

2755
02:12:23,990 --> 02:12:21,179
representative for the European Space

2756
02:12:26,810 --> 02:12:24,000
Agency so Antonella first off

2757
02:12:28,490 --> 02:12:26,820
many congratulations it's been a

2758
02:12:29,629 --> 02:12:28,500
wonderful morning so far how are you

2759
02:12:32,450 --> 02:12:29,639
doing

2760
02:12:35,810 --> 02:12:32,460
it is amazing it has been an amazing

2761
02:12:39,470 --> 02:12:35,820
morning and the team made it look so

2762
02:12:41,629 --> 02:12:39,480
easy I we know how many years of

2763
02:12:43,910 --> 02:12:41,639
preparation that were behind the moves

2764
02:12:46,609 --> 02:12:43,920
this morning but it just looks so

2765
02:12:49,010 --> 02:12:46,619
amazingly easy I'm so delighted to

2766
02:12:52,069 --> 02:12:49,020
represent the European Space Agency at

2767
02:12:56,330 --> 02:12:52,079
this time and this is the moment we have

2768
02:12:59,569 --> 02:12:56,340
been waiting for for so long so we are

2769
02:13:01,609 --> 02:12:59,579
ready to move to the next step

2770
02:13:02,990 --> 02:13:01,619
it's incredible so for those of you that

2771
02:13:05,589 --> 02:13:03,000
may have just joined us today that we

2772
02:13:08,930 --> 02:13:05,599
deployed the uh the the second and final

2773
02:13:10,669 --> 02:13:08,940
uh to the primary mirror and uh that was

2774
02:13:12,589 --> 02:13:10,679
a major commissioning exercise there are

2775
02:13:14,089 --> 02:13:12,599
there are definitely things to come but

2776
02:13:16,490 --> 02:13:14,099
yeah this is you know what's been

2777
02:13:18,109 --> 02:13:16,500
accomplished is absolutely the story and

2778
02:13:20,290 --> 02:13:18,119
really incredible

2779
02:13:23,750 --> 02:13:20,300
um you're looking at live coverage

2780
02:13:24,890 --> 02:13:23,760
Center yeah command line and that looks

2781
02:13:26,270 --> 02:13:24,900
good too occasionally you'll hear me

2782
02:13:29,270 --> 02:13:26,280
pause because we're listening to the

2783
02:13:31,790 --> 02:13:29,280
commands so uh that's all fine

2784
02:13:34,310 --> 02:13:31,800
and uh in between commands we'll have a

2785
02:13:37,250 --> 02:13:34,320
chance to talk to Antonella so um

2786
02:13:39,350 --> 02:13:37,260
Antonella you are an an astrophysicist

2787
02:13:41,209 --> 02:13:39,360
an astronomer and uh tell us a bit about

2788
02:13:42,290 --> 02:13:41,219
some of the major science goals that

2789
02:13:44,209 --> 02:13:42,300
you're looking forward to but maybe

2790
02:13:46,370 --> 02:13:44,219
maybe before we do that we should back

2791
02:13:48,589 --> 02:13:46,380
up a little bit and talk about infrared

2792
02:13:51,410 --> 02:13:48,599
well why is web an infrared telescope

2793
02:13:54,950 --> 02:13:51,420
and and why is that so important

2794
02:13:57,890 --> 02:13:54,960
it's easy for us because it's

2795
02:14:00,470 --> 02:13:57,900
um the sources that web wants to look at

2796
02:14:02,810 --> 02:14:00,480
and meet indeed for example when we look

2797
02:14:05,510 --> 02:14:02,820
at the distant Universe we're all

2798
02:14:08,330 --> 02:14:05,520
familiar with the Hubble they feel that

2799
02:14:14,390 --> 02:14:08,340
the Hubble took several years ago and we

2800
02:14:20,089 --> 02:14:16,550
the big guy just at the very beginning

2801
02:14:23,450 --> 02:14:20,099
Hubble with the 2.4 meter could push us

2802
02:14:26,270 --> 02:14:23,460
to see that Horizon web will go way past

2803
02:14:29,589 --> 02:14:26,280
and look at the first few Millionaires

2804
02:14:33,530 --> 02:14:29,599
and see those galaxies that are small

2805
02:14:35,689 --> 02:14:33,540
irregular compact we want to know how

2806
02:14:40,430 --> 02:14:35,699
those galaxies became the Milky Way

2807
02:14:42,770 --> 02:14:40,440
after that and those galaxies emit in

2808
02:14:46,129 --> 02:14:42,780
the infrared here you see a beautiful

2809
02:14:49,729 --> 02:14:46,139
fly through the um the hubbledy field

2810
02:14:52,370 --> 02:14:49,739
and it's amazing that in the size of a

2811
02:14:54,950 --> 02:14:52,380
pencil we could see thousands and

2812
02:14:59,089 --> 02:14:54,960
thousands of galaxies including some

2813
02:15:01,850 --> 02:14:59,099
very very old as I said as old as 400

2814
02:15:03,189 --> 02:15:01,860
million years after the big bang so

2815
02:15:06,169 --> 02:15:03,199
we're talking

2816
02:15:08,810 --> 02:15:06,179
13.2 billion years old and those

2817
02:15:10,910 --> 02:15:08,820
galaxies look very different from today

2818
02:15:13,790 --> 02:15:10,920
and so I think the challenge for the

2819
02:15:17,390 --> 02:15:13,800
astronomers is to understand how they

2820
02:15:20,209 --> 02:15:17,400
evolve from how we look at them then and

2821
02:15:20,870 --> 02:15:20,219
how we see them today and where we'll do

2822
02:15:24,709 --> 02:15:20,880
that

2823
02:15:27,350 --> 02:15:24,719
web will also make be able to actually

2824
02:15:29,890 --> 02:15:27,360
individually take Spectra of these

2825
02:15:32,569 --> 02:15:29,900
galaxies because it has powerful

2826
02:15:34,490 --> 02:15:32,579
spectrograph on board including for

2827
02:15:37,010 --> 02:15:34,500
example near spec the word for

2828
02:15:40,129 --> 02:15:37,020
spectrograph provided by the European

2829
02:15:43,430 --> 02:15:40,139
space agency and near spec will be able

2830
02:15:46,729 --> 02:15:43,440
to actually take Spectra and and for all

2831
02:15:49,669 --> 02:15:46,739
of you who are watching Spectra are when

2832
02:15:51,589 --> 02:15:49,679
the light of an astronomical Target gets

2833
02:15:52,450 --> 02:15:51,599
split into its component like for

2834
02:15:55,010 --> 02:15:52,460
example

2835
02:15:58,430 --> 02:15:55,020
raindrop let's do after a thunderstorm

2836
02:16:00,770 --> 02:15:58,440
and you see a rainbow so why Spectra are

2837
02:16:04,490 --> 02:16:00,780
important because Factor telestronomer

2838
02:16:07,069 --> 02:16:04,500
what the object is made of images tell

2839
02:16:09,530 --> 02:16:07,079
us how objects look like but we really

2840
02:16:12,229 --> 02:16:09,540
want to know the physical chemical

2841
02:16:15,290 --> 02:16:12,239
composition the elements that are there

2842
02:16:19,250 --> 02:16:15,300
and for that we inspector and because

2843
02:16:22,010 --> 02:16:19,260
web will be so powerful 100 times more

2844
02:16:23,930 --> 02:16:22,020
powerful than web with do believe that

2845
02:16:26,990 --> 02:16:23,940
we'll be able to expect that all these

2846
02:16:29,390 --> 02:16:27,000
faint objects that we see at the edge of

2847
02:16:31,669 --> 02:16:29,400
our observable universe we are ready to

2848
02:16:32,870 --> 02:16:31,679
continue with it's absolutely incredible

2849
02:16:33,950 --> 02:16:32,880
for those of you that might not be

2850
02:16:35,209 --> 02:16:33,960
familiar with the Hubble Deep Field

2851
02:16:37,190 --> 02:16:35,219
which was the image that we had started

2852
02:16:39,589 --> 02:16:37,200
with there when Antonella says the size

2853
02:16:41,990 --> 02:16:39,599
of a pencil it's looking down the narrow

2854
02:16:44,209 --> 02:16:42,000
part and so that tiny little bit of the

2855
02:16:46,790 --> 02:16:44,219
sky anywhere you look in the sky there

2856
02:16:50,089 --> 02:16:46,800
are many thousands very very far away

2857
02:16:52,009 --> 02:16:50,099
from us so um again and for our viewers

2858
02:16:53,870 --> 02:16:52,019
we often get a lot of questions about

2859
02:16:55,969 --> 02:16:53,880
how is it that we're able to look back

2860
02:16:57,230 --> 02:16:55,979
in time a lot of people I've actually

2861
02:16:59,870 --> 02:16:57,240
gotten questions on social media

2862
02:17:01,490 --> 02:16:59,880
recently about what direction do you

2863
02:17:02,929 --> 02:17:01,500
need to look to see that far back in

2864
02:17:04,610 --> 02:17:02,939
time maybe you could give us just a

2865
02:17:06,709 --> 02:17:04,620
little bit of an astronomy lesson about

2866
02:17:07,910 --> 02:17:06,719
how is it that we can view the normal

2867
02:17:11,030 --> 02:17:07,920
universe

2868
02:17:14,450 --> 02:17:11,040
yes you look anywhere because wherever

2869
02:17:16,549 --> 02:17:14,460
you look your eyesight basically looks

2870
02:17:18,830 --> 02:17:16,559
as far as you can go and the farthest

2871
02:17:21,469 --> 02:17:18,840
you go you go the farthest you go back

2872
02:17:24,650 --> 02:17:21,479
in time so as I was saying this very

2873
02:17:27,770 --> 02:17:24,660
faint Galaxy that we see in the Hubble

2874
02:17:31,429 --> 02:17:27,780
the field I've traveled for the light

2875
02:17:34,849 --> 02:17:31,439
for those galaxies has traveled for 13.2

2876
02:17:38,030 --> 02:17:34,859
billion years so we see them today as

2877
02:17:40,849 --> 02:17:38,040
they were 13 billion years ago and this

2878
02:17:43,610 --> 02:17:40,859
is the powerful of this amazing

2879
02:17:45,589 --> 02:17:43,620
telescope who can actually look at the

2880
02:17:47,990 --> 02:17:45,599
beginning of the formation of the

2881
02:17:50,389 --> 02:17:48,000
universe because one of the things that

2882
02:17:53,270 --> 02:17:50,399
uh rev will do you know it will be

2883
02:17:56,389 --> 02:17:53,280
focusing on Origins what is the origin

2884
02:17:59,270 --> 02:17:56,399
of our universe as well as other origin

2885
02:18:02,150 --> 02:17:59,280
things like how stars form what's the

2886
02:18:05,629 --> 02:18:02,160
origin of stars so you can see the web

2887
02:18:08,330 --> 02:18:05,639
is going to look we hope in the up to

2888
02:18:10,849 --> 02:18:08,340
the first hundred or two hundred million

2889
02:18:12,830 --> 02:18:10,859
years after the big time if we are

2890
02:18:15,049 --> 02:18:12,840
really lucky we might even see the first

2891
02:18:18,230 --> 02:18:15,059
star Thomas was talking about first star

2892
02:18:21,290 --> 02:18:18,240
earlier on that's a challenge but this

2893
02:18:23,389 --> 02:18:21,300
is one maybe of the surprises that the

2894
02:18:26,330 --> 02:18:23,399
web will bring us together with many

2895
02:18:28,009 --> 02:18:26,340
others I'm sure

2896
02:18:30,169 --> 02:18:28,019
you know I've also gotten questions

2897
02:18:32,270 --> 02:18:30,179
about who gets to use web you know I

2898
02:18:33,410 --> 02:18:32,280
mean how is it you know one of the

2899
02:18:34,969 --> 02:18:33,420
questions that I actually got on social

2900
02:18:36,650 --> 02:18:34,979
media is you know the only people from

2901
02:18:39,110 --> 02:18:36,660
NASA get to use web and that's that's

2902
02:18:40,549 --> 02:18:39,120
very much not the case are you you work

2903
02:18:41,750 --> 02:18:40,559
at the Space Telescope Science Institute

2904
02:18:42,950 --> 02:18:41,760
where a lot of this happens it could

2905
02:18:46,070 --> 02:18:42,960
give us a sense

2906
02:18:49,250 --> 02:18:46,080
how how is time on web allocated

2907
02:18:52,669 --> 02:18:49,260
absolutely so the entire worldwide

2908
02:18:55,849 --> 02:18:52,679
Community can can use web to observe

2909
02:18:58,190 --> 02:18:55,859
they just need to have a good idea and a

2910
02:19:00,830 --> 02:18:58,200
laptop and an internet connection and

2911
02:19:03,290 --> 02:19:00,840
they can submit their proposal and their

2912
02:19:06,230 --> 02:19:03,300
proposal they will say I want to use

2913
02:19:09,410 --> 02:19:06,240
these instruments to make this amazing

2914
02:19:12,349 --> 02:19:09,420
Discovery will be evaluated by a group

2915
02:19:16,610 --> 02:19:12,359
of peers experts in the various Fields

2916
02:19:19,070 --> 02:19:16,620
And if that idea is compelling that idea

2917
02:19:21,650 --> 02:19:19,080
will be scheduled on the telescope and

2918
02:19:24,889 --> 02:19:21,660
as we speak we have already a first year

2919
02:19:27,410 --> 02:19:24,899
already scheduled of observations that

2920
02:19:29,629 --> 02:19:27,420
have been given out to the community to

2921
02:19:32,030 --> 02:19:29,639
the instrument Builders who have the

2922
02:19:34,969 --> 02:19:32,040
right to get the fruit of our hard work

2923
02:19:38,469 --> 02:19:34,979
over so many years and the early release

2924
02:19:40,910 --> 02:19:38,479
signs scientists

2925
02:19:47,330 --> 02:19:40,920
definitely it's ready to begin with the

2926
02:19:47,340 --> 02:20:11,050
foreign

2927
02:20:17,030 --> 02:20:14,389
for for doing such an amazing amazing

2928
02:20:20,330 --> 02:20:17,040
world you know for astronomers this is

2929
02:20:22,849 --> 02:20:20,340
the biggest gift that we can get and

2930
02:20:25,070 --> 02:20:22,859
we're just looking forward to see what

2931
02:20:27,889 --> 02:20:25,080
level it has but I was saying the early

2932
02:20:30,650 --> 02:20:27,899
release science this is something that

2933
02:20:33,469 --> 02:20:30,660
the director of Staci use some of his

2934
02:20:36,889 --> 02:20:33,479
precious directory with rational hours

2935
02:20:39,830 --> 02:20:36,899
to actually tell the community submit

2936
02:20:42,590 --> 02:20:39,840
proposals for approximately a couple of

2937
02:20:44,809 --> 02:20:42,600
hundred hours and they will be evaluated

2938
02:20:47,510 --> 02:20:44,819
with this travel there will be done

2939
02:20:49,790 --> 02:20:47,520
right away the observation will become

2940
02:20:52,190 --> 02:20:49,800
public they will go in their time they

2941
02:20:54,530 --> 02:20:52,200
will be made available to all because

2942
02:20:56,889 --> 02:20:54,540
this observation will show the

2943
02:20:59,510 --> 02:20:56,899
capability of this very powerful

2944
02:21:01,610 --> 02:20:59,520
Observatory so there are a number of

2945
02:21:03,770 --> 02:21:01,620
programs some of Which Europeans that

2946
02:21:06,349 --> 02:21:03,780
are going to execute in the very very

2947
02:21:10,389 --> 02:21:06,359
first few months and those are the ones

2948
02:21:12,969 --> 02:21:10,399
that will show the work or how actually

2949
02:21:16,190 --> 02:21:12,979
web performs

2950
02:21:19,190 --> 02:21:16,200
before that we will have the early

2951
02:21:22,070 --> 02:21:19,200
release observations and those are

2952
02:21:26,090 --> 02:21:22,080
really the ones that I'm waiting for to

2953
02:21:28,910 --> 02:21:26,100
see this is super secret list of targets

2954
02:21:31,250 --> 02:21:28,920
I don't know you know what targets will

2955
02:21:34,969 --> 02:21:31,260
be but I know one thing that they will

2956
02:21:37,990 --> 02:21:34,979
be absolutely spectacular and they will

2957
02:21:41,950 --> 02:21:38,000
be shown to the world

2958
02:21:43,969 --> 02:21:41,960
200 days after launch at the end of the

2959
02:21:48,290 --> 02:21:43,979
commissioning instrument commissioning

2960
02:21:50,510 --> 02:21:48,300
but I hold your brand because it will

2961
02:21:52,429 --> 02:21:50,520
they will be just I've been working at

2962
02:21:54,170 --> 02:21:52,439
the uh so we've talked a bit about the

2963
02:21:56,389 --> 02:21:54,180
early universe and I know that another

2964
02:21:58,130 --> 02:21:56,399
you know primary science goal of web has

2965
02:21:59,630 --> 02:21:58,140
to do with exoplanets we mentioned that

2966
02:22:00,889 --> 02:21:59,640
a little bit with Thomas but I think

2967
02:22:03,770 --> 02:22:00,899
maybe you could take us a bit more

2968
02:22:05,750 --> 02:22:03,780
through how does web actually analyze

2969
02:22:07,450 --> 02:22:05,760
yeah the atmospheres of planets around

2970
02:22:10,130 --> 02:22:07,460
other stars

2971
02:22:12,650 --> 02:22:10,140
absolutely so this is a technique that

2972
02:22:14,110 --> 02:22:12,660
Hubble had already pioneered and I want

2973
02:22:16,910 --> 02:22:14,120
just to to

2974
02:22:18,710 --> 02:22:16,920
tell the community who is listening you

2975
02:22:22,070 --> 02:22:18,720
know when Harbor was launch we didn't

2976
02:22:25,250 --> 02:22:22,080
know exoplanets now we know that every

2977
02:22:27,889 --> 02:22:25,260
Star is exoplanet around so this

2978
02:22:31,670 --> 02:22:27,899
technique allows to study the atmosphere

2979
02:22:35,450 --> 02:22:31,680
of the exoplanet as they move in front

2980
02:22:38,510 --> 02:22:35,460
of their hostiles and by doing that we

2981
02:22:40,429 --> 02:22:38,520
can see but via spectroscopy will

2982
02:22:43,070 --> 02:22:40,439
actually the components of that

2983
02:22:45,290 --> 02:22:43,080
atmosphere and so you can see here the

2984
02:22:48,349 --> 02:22:45,300
planet basically moving in front of the

2985
02:22:51,790 --> 02:22:48,359
star the lights did and the in the

2986
02:22:54,710 --> 02:22:51,800
infrared we can see uh important

2987
02:22:57,410 --> 02:22:54,720
component elements that are the building

2988
02:23:01,870 --> 02:22:57,420
block We Believe of life in the future

2989
02:23:05,210 --> 02:23:01,880
so water vapor uh carbon dioxide

2990
02:23:08,210 --> 02:23:05,220
oxygen all the complex molecules based

2991
02:23:11,210 --> 02:23:08,220
on oxygen why we're looking for these

2992
02:23:14,150 --> 02:23:11,220
molecules because the ultimate goal is

2993
02:23:16,849 --> 02:23:14,160
to see if there is life out there so we

2994
02:23:19,370 --> 02:23:16,859
start looking at the building blocks and

2995
02:23:22,250 --> 02:23:19,380
the humble has already moved the field

2996
02:23:24,410 --> 02:23:22,260
forward but it's a small telescope we do

2997
02:23:27,110 --> 02:23:24,420
believe that being a hundred times more

2998
02:23:30,110 --> 02:23:27,120
sensitive web will just revolutionize

2999
02:23:33,170 --> 02:23:30,120
this field so our knowledge of exoplanet

3000
02:23:36,530 --> 02:23:33,180
composition will be just spectacular and

3001
02:23:39,590 --> 02:23:36,540
maybe we will find another Earth out

3002
02:23:42,969 --> 02:23:39,600
there that's the big you know uh award

3003
02:23:45,230 --> 02:23:42,979
for for this work

3004
02:23:47,330 --> 02:23:45,240
absolutely wonderful Antonella thank you

3005
02:23:49,910 --> 02:23:47,340
so much for joining us I hope the the

3006
02:23:51,530 --> 02:23:49,920
day continues to be joyful and exciting

3007
02:23:53,330 --> 02:23:51,540
and uh and after this we all get a bit

3008
02:23:55,309 --> 02:23:53,340
of a break so I thank you again for

3009
02:23:57,590 --> 02:23:55,319
joining us that's uh that's Dr Antonella

3010
02:23:59,030 --> 02:23:57,600
Nota the uh the Europeans uh the

3011
02:24:00,290 --> 02:23:59,040
European Space Agency representative

3012
02:24:02,150 --> 02:24:00,300
here at the Space Telescope Science

3013
02:24:09,110 --> 02:24:02,160
Institute thank you so much thank you

3014
02:24:14,389 --> 02:24:10,910
so the next uh person we're going to be

3015
02:24:15,590 --> 02:24:14,399
talking to is uh is Joe uh spofera and

3016
02:24:17,150 --> 02:24:15,600
uh he will tell us a little bit more

3017
02:24:18,830 --> 02:24:17,160
about some of the engineering aspects of

3018
02:24:20,150 --> 02:24:18,840
the web telescope for those of you that

3019
02:24:22,130 --> 02:24:20,160
are just joining us you're looking at

3020
02:24:23,929 --> 02:24:22,140
live commissioning of the James Webb

3021
02:24:25,490 --> 02:24:23,939
Space Telescope I'm here at the Space

3022
02:24:28,070 --> 02:24:25,500
Telescope Science Institute in Baltimore

3023
02:24:29,510 --> 02:24:28,080
Maryland I'm Michelle Thaller and Joe

3024
02:24:30,530 --> 02:24:29,520
thank you so much for for joining us

3025
02:24:33,050 --> 02:24:30,540
today

3026
02:24:34,550 --> 02:24:33,060
um so to begin with please introduce

3027
02:24:36,830 --> 02:24:34,560
yourself and tell us a bit about your

3028
02:24:39,410 --> 02:24:36,840
role on the web telescope

3029
02:24:41,210 --> 02:24:39,420
uh yeah so yeah you mentioned my name's

3030
02:24:42,469 --> 02:24:41,220
Joseph so

3031
02:24:44,570 --> 02:24:42,479
um I've been working on the web

3032
02:24:47,570 --> 02:24:44,580
telescope for 16 and a half years now

3033
02:24:50,330 --> 02:24:47,580
with Northrop Grumman uh currently the

3034
02:24:52,429 --> 02:24:50,340
program Dynamics lead uh for Northrop as

3035
02:24:54,590 --> 02:24:52,439
well as doing a lot of lead

3036
02:24:56,690 --> 02:24:54,600
responsibilities for deployments with

3037
02:24:57,710 --> 02:24:56,700
the team that we have uh both what we've

3038
02:25:01,370 --> 02:24:57,720
done on the ground and what we're doing

3039
02:25:02,929 --> 02:25:01,380
today here at the mock for on orbit

3040
02:25:04,790 --> 02:25:02,939
and how's how's the morning gone for you

3041
02:25:06,170 --> 02:25:04,800
are you are you as excited as everybody

3042
02:25:07,010 --> 02:25:06,180
else and happy that things have gone

3043
02:25:09,650 --> 02:25:07,020
well

3044
02:25:10,969 --> 02:25:09,660
yeah it's it's been going fantastic it

3045
02:25:12,230 --> 02:25:10,979
really has for the last two weeks as

3046
02:25:14,570 --> 02:25:12,240
well kind of everything we could have

3047
02:25:17,389 --> 02:25:14,580
hoped for uh with all the operations

3048
02:25:19,910 --> 02:25:17,399
have really gone quite nominal and quite

3049
02:25:23,510 --> 02:25:19,920
to our expectations so it's been a great

3050
02:25:27,110 --> 02:25:25,550
so uh I guess one of the things that we

3051
02:25:29,030 --> 02:25:27,120
have that we can show our audience are

3052
02:25:30,830 --> 02:25:29,040
some footage from the tests that came

3053
02:25:32,630 --> 02:25:30,840
before the launch of the James Webb

3054
02:25:34,849 --> 02:25:32,640
Space Telescope different tests in the

3055
02:25:36,349 --> 02:25:34,859
clean room so I I believe we're gonna

3056
02:25:38,450 --> 02:25:36,359
roll some video and you can tell me what

3057
02:25:41,090 --> 02:25:38,460
we're seeing here please Joe

3058
02:25:42,590 --> 02:25:41,100
yeah so this is uh actually the wing

3059
02:25:44,809 --> 02:25:42,600
we're deploying today so that was the

3060
02:25:46,370 --> 02:25:44,819
ground deployment test for that Wing the

3061
02:25:48,410 --> 02:25:46,380
the last time through

3062
02:25:50,150 --> 02:25:48,420
uh and actually if we end up deploying

3063
02:25:51,950 --> 02:25:50,160
both when deployed this is our our

3064
02:25:53,510 --> 02:25:51,960
pre-observatory environment deployment

3065
02:25:55,910 --> 02:25:53,520
was the last time that both wings were

3066
02:25:57,889 --> 02:25:55,920
deployed at the same time on the ground

3067
02:26:00,110 --> 02:25:57,899
uh so you can kind of see the the

3068
02:26:02,450 --> 02:26:00,120
operations that went through there with

3069
02:26:05,809 --> 02:26:02,460
all of the individuals in the high Bay

3070
02:26:07,309 --> 02:26:05,819
Performing their jobs getting through so

3071
02:26:09,349 --> 02:26:07,319
um down on the left there watching that

3072
02:26:11,570 --> 02:26:09,359
Wing deployment uh that's Paul Reynolds

3073
02:26:13,250 --> 02:26:11,580
who's downstairs right now uh as the

3074
02:26:15,950 --> 02:26:13,260
deputy doing the deployment kind of

3075
02:26:17,330 --> 02:26:15,960
watching for what's going on both like

3076
02:26:19,309 --> 02:26:17,340
he would have on the floor there doing

3077
02:26:20,809 --> 02:26:19,319
uh observing the deployment looking to

3078
02:26:22,670 --> 02:26:20,819
see any interaction seeing what's

3079
02:26:24,790 --> 02:26:22,680
happening and uh he's down there right

3080
02:26:27,590 --> 02:26:24,800
now today with the rest of the mock team

3081
02:26:29,030 --> 02:26:27,600
doing that deployment watching for the

3082
02:26:32,690 --> 02:26:29,040
Telemetry to make sure we see what we

3083
02:26:35,809 --> 02:26:34,309
and actually in this footage you can see

3084
02:26:38,210 --> 02:26:35,819
that there's sort of this this black

3085
02:26:39,889 --> 02:26:38,220
border on the outside of the mirror and

3086
02:26:42,290 --> 02:26:39,899
and that's for a very specific purpose

3087
02:26:43,610 --> 02:26:42,300
maybe you can tell us a bit about that

3088
02:26:45,410 --> 02:26:43,620
uh you're speaking about the black

3089
02:26:47,150 --> 02:26:45,420
quarter on the very outsides of all the

3090
02:26:50,990 --> 02:26:47,160
mirrors yes that's right yeah that's

3091
02:26:52,429 --> 02:26:51,000
there for uh the frill section that goes

3092
02:26:54,110 --> 02:26:52,439
around the outside the fixed frill

3093
02:26:57,170 --> 02:26:54,120
outside of the the mirrors themselves

3094
02:26:59,090 --> 02:26:57,180
for uh thermal purposes so that you kind

3095
02:27:01,969 --> 02:26:59,100
of have this deep black right next to

3096
02:27:07,010 --> 02:27:01,979
the mirrors that would not pick up the

3097
02:27:10,429 --> 02:27:08,570
and then of course uh those beautiful

3098
02:27:11,750 --> 02:27:10,439
that beautiful gold coating and that

3099
02:27:13,250 --> 02:27:11,760
that's something that we get a lot of

3100
02:27:16,490 --> 02:27:13,260
questions about as to why why the

3101
02:27:18,349 --> 02:27:16,500
mirrors are are coated with gold uh can

3102
02:27:19,730 --> 02:27:18,359
you give us an explanation for that

3103
02:27:21,889 --> 02:27:19,740
please

3104
02:27:23,230 --> 02:27:21,899
uh I'm probably not the best person to

3105
02:27:26,389 --> 02:27:23,240
give you the explanations

3106
02:27:27,889 --> 02:27:26,399
the best material that was determined by

3107
02:27:29,809 --> 02:27:27,899
you know a number of scientists and

3108
02:27:31,670 --> 02:27:29,819
Engineers to to give us the best

3109
02:27:33,130 --> 02:27:31,680
performance for the Optics and for

3110
02:27:35,450 --> 02:27:33,140
taking data

3111
02:27:37,309 --> 02:27:35,460
when you see the deployment of the tests

3112
02:27:38,990 --> 02:27:37,319
that were done the thing that amazes me

3113
02:27:40,969 --> 02:27:39,000
is that all this was done here on Earth

3114
02:27:43,070 --> 02:27:40,979
there was no way to take this up into

3115
02:27:44,510 --> 02:27:43,080
space and test it in space and of course

3116
02:27:46,730 --> 02:27:44,520
in space you don't have the influence of

3117
02:27:48,650 --> 02:27:46,740
gravity whereas here on Earth you do how

3118
02:27:51,349 --> 02:27:48,660
do you design a test that you know that

3119
02:27:52,730 --> 02:27:51,359
it's it's going to work in zero gravity

3120
02:27:54,349 --> 02:27:52,740
you know how do you design to take that

3121
02:27:55,670 --> 02:27:54,359
into account when you're testing here on

3122
02:27:58,370 --> 02:27:55,680
Earth

3123
02:27:59,750 --> 02:27:58,380
right so the key thing there is uh we

3124
02:28:02,210 --> 02:27:59,760
have to have a very good understanding

3125
02:28:03,710 --> 02:28:02,220
of the loads that we want to see in the

3126
02:28:05,510 --> 02:28:03,720
deployment and the loads that we want to

3127
02:28:07,969 --> 02:28:05,520
kind of counteract or counterbalance in

3128
02:28:10,610 --> 02:28:07,979
the gravity field so we do want to try

3129
02:28:11,750 --> 02:28:10,620
to maintain the the resistances that

3130
02:28:13,150 --> 02:28:11,760
we're trying to characterize or

3131
02:28:16,070 --> 02:28:13,160
understand so there are certain

3132
02:28:17,570 --> 02:28:16,080
harnessing or insulation that provides a

3133
02:28:18,830 --> 02:28:17,580
drag or resistance in the deployment we

3134
02:28:20,630 --> 02:28:18,840
still want to capture that in the test

3135
02:28:22,610 --> 02:28:20,640
so we can characterize it understand it

3136
02:28:24,469 --> 02:28:22,620
on the ground but you do need to

3137
02:28:25,610 --> 02:28:24,479
counteract the gravity you need to take

3138
02:28:27,410 --> 02:28:25,620
away the fact that there's weight

3139
02:28:29,750 --> 02:28:27,420
reacting on hinges and different

3140
02:28:32,389 --> 02:28:29,760
locations in the Deployable Hardware so

3141
02:28:34,730 --> 02:28:32,399
uh there is an offload system that we

3142
02:28:37,070 --> 02:28:34,740
use for that and it was visible a little

3143
02:28:38,990 --> 02:28:37,080
bit in the video that you did show and I

3144
02:28:41,090 --> 02:28:39,000
don't know if going back to that or not

3145
02:28:43,190 --> 02:28:41,100
but uh in the case of the Wings there

3146
02:28:45,469 --> 02:28:43,200
was an overhead system and actually you

3147
02:28:48,110 --> 02:28:45,479
can see it right here so there's a cable

3148
02:28:49,490 --> 02:28:48,120
going up from the wing itself uh from

3149
02:28:52,070 --> 02:28:49,500
some Hardware attached on the back so

3150
02:28:54,469 --> 02:28:52,080
that we can attach basically through the

3151
02:28:56,990 --> 02:28:54,479
CG of the wing and you can see the cable

3152
02:28:58,910 --> 02:28:57,000
running up to the crane structure to

3153
02:29:00,830 --> 02:28:58,920
what looks sort of like a balanced beam

3154
02:29:03,170 --> 02:29:00,840
or a teeter-totter that's up there and

3155
02:29:05,750 --> 02:29:03,180
that cable that the beam that's up there

3156
02:29:08,030 --> 02:29:05,760
can pivot and rotate and the rotation

3157
02:29:10,190 --> 02:29:08,040
points aligned to the rotation axis of

3158
02:29:11,870 --> 02:29:10,200
the wing so that you get a one-to-one

3159
02:29:14,510 --> 02:29:11,880
rotation there as the wing is turning

3160
02:29:16,790 --> 02:29:14,520
it's turning the hardware up above in

3161
02:29:19,670 --> 02:29:16,800
the crane area and at the opposite end

3162
02:29:21,230 --> 02:29:19,680
of that rotating arm is also a weight to

3163
02:29:24,230 --> 02:29:21,240
kind of balance that out so you get a

3164
02:29:25,969 --> 02:29:24,240
load or attention in that cable that's

3165
02:29:28,309 --> 02:29:25,979
effectively equivalent to what the wing

3166
02:29:30,770 --> 02:29:28,319
weighs so that now as you're rotating

3167
02:29:32,750 --> 02:29:30,780
the hinges that you have in this system

3168
02:29:35,090 --> 02:29:32,760
don't actually see the weight of the

3169
02:29:37,730 --> 02:29:35,100
wing they're nearly weightless you know

3170
02:29:40,130 --> 02:29:37,740
as as best as we can on the grounds that

3171
02:29:42,170 --> 02:29:40,140
you can Instead try to capture just the

3172
02:29:43,849 --> 02:29:42,180
loads of the nominal flight deployment

3173
02:29:45,230 --> 02:29:43,859
which would be like I mentioned

3174
02:29:46,730 --> 02:29:45,240
something like a harness or some

3175
02:29:49,130 --> 02:29:46,740
insulation

3176
02:29:50,630 --> 02:29:49,140
or some you know very low nominal drag

3177
02:29:53,750 --> 02:29:50,640
that you get from driving at the one

3178
02:29:57,349 --> 02:29:56,210
really wonderful

3179
02:29:59,150 --> 02:29:57,359
so it's

3180
02:30:00,830 --> 02:29:59,160
a pleasure having you here Joe you know

3181
02:30:02,450 --> 02:30:00,840
congratulations again on everything

3182
02:30:03,950 --> 02:30:02,460
that's happened this morning and the

3183
02:30:05,330 --> 02:30:03,960
continued commissioning of the sales

3184
02:30:08,090 --> 02:30:05,340
book is coming up

3185
02:30:10,730 --> 02:30:08,100
so uh we'll we'll let you go thank you

3186
02:30:13,010 --> 02:30:10,740
so much for taking us to consistent

3187
02:30:14,990 --> 02:30:13,020
thank you very good to have you here

3188
02:30:16,250 --> 02:30:15,000
so for uh those people in the audience

3189
02:30:17,929 --> 02:30:16,260
that are just joining us you're looking

3190
02:30:20,030 --> 02:30:17,939
at live commissioning of the James Webb

3191
02:30:22,969 --> 02:30:20,040
Space Telescope today we have successful

3192
02:30:25,130 --> 02:30:22,979
deployed yeah uh with the second wing of

3193
02:30:27,290 --> 02:30:25,140
the primary mirror we now have the whole

3194
02:30:29,389 --> 02:30:27,300
primary mayor together and we are

3195
02:30:31,670 --> 02:30:29,399
currently uh involved in latching that

3196
02:30:33,349 --> 02:30:31,680
into its final place so that that

3197
02:30:34,849 --> 02:30:33,359
procedurally good happening for a couple

3198
02:30:37,130 --> 02:30:34,859
more hours and we'll be here to the end

3199
02:30:38,570 --> 02:30:37,140
of it uh right now however uh we will

3200
02:30:40,490 --> 02:30:38,580
probably take a short break in our

3201
02:30:41,990 --> 02:30:40,500
commentary and when we come back we will

3202
02:30:43,790 --> 02:30:42,000
talk to some more experts on the the

3203
02:30:45,410 --> 02:30:43,800
James Webb Space Telescope you'll be

3204
02:30:47,030 --> 02:30:45,420
seeing more live coverage from the mock

3205
02:30:48,889 --> 02:30:47,040
the mission operations center here at

3206
02:30:51,230 --> 02:30:48,899
the Space Telescope Science Institute in

3207
02:30:52,610 --> 02:30:51,240
Baltimore Maryland and I'll be here to

3208
02:30:55,010 --> 02:30:52,620
take more of your questions on social

3209
02:30:56,870 --> 02:30:55,020
media once again you can use the hashtag

3210
02:30:58,849 --> 02:30:56,880
unfold the universe and we'll get to

3211
02:31:00,170 --> 02:30:58,859
some questions after the break so thank

3212
02:31:02,990 --> 02:31:00,180
you very much and we'll we'll see you

3213
02:31:12,849 --> 02:31:05,770
hmm

3214
02:31:12,859 --> 02:31:16,670
in progress

3215
02:31:30,950 --> 02:31:19,190
and the mirror may just complete

3216
02:31:30,960 --> 02:31:33,469
um

3217
02:31:39,170 --> 02:31:35,690
okay and OC

3218
02:31:40,490 --> 02:31:39,180
um definitely have confirmed that um I

3219
02:31:44,150 --> 02:31:40,500
just look good we're ready to continue

3220
02:31:50,030 --> 02:31:44,160
with the three door latched oh

3221
02:31:50,040 --> 02:31:53,510
standby

3222
02:31:53,520 --> 02:32:14,889
anyway

3223
02:32:38,630 --> 02:32:34,750
thank you

3224
02:32:43,610 --> 02:32:38,640
um you could just steal one off one of

3225
02:32:43,620 --> 02:33:00,110
self-cent matters

3226
02:33:04,450 --> 02:33:02,330
hello Julie

3227
02:33:08,929 --> 02:33:04,460
hello

3228
02:33:15,650 --> 02:33:12,650
we're currently in our final steps of

3229
02:33:19,070 --> 02:33:15,660
the first latching of the three degree

3230
02:33:21,110 --> 02:33:19,080
of Freedom uh latch this is bringing it

3231
02:33:23,929 --> 02:33:21,120
up to its full load

3232
02:33:26,570 --> 02:33:23,939
uh they've been as you've been talking

3233
02:33:28,849 --> 02:33:26,580
with your other guests you can hear that

3234
02:33:30,230 --> 02:33:28,859
they've been talking through all the

3235
02:33:32,929 --> 02:33:30,240
steps as they move through all the

3236
02:33:35,330 --> 02:33:32,939
different levels of load on the on the

3237
02:33:37,969 --> 02:33:35,340
latches and they're coming up on what

3238
02:33:39,590 --> 02:33:37,979
they call the three-door latch and it's

3239
02:33:42,830 --> 02:33:39,600
going to be

3240
02:33:47,270 --> 02:33:42,840
um uh loaded up to its final and uh

3241
02:33:51,170 --> 02:33:49,010
as they've been going through they've

3242
02:33:53,450 --> 02:33:51,180
been checking out their system checking

3243
02:33:55,070 --> 02:33:53,460
out their Motors making sure that each

3244
02:33:58,010 --> 02:33:55,080
step of the way that everything's good

3245
02:34:01,370 --> 02:33:58,020
they're in their final checkouts now and

3246
02:34:02,990 --> 02:34:01,380
this first complete latch is a is a big

3247
02:34:05,150 --> 02:34:03,000
milestone

3248
02:34:07,130 --> 02:34:05,160
excellent for those of you who've just

3249
02:34:08,929 --> 02:34:07,140
joined us uh that's uh Julie van kempen

3250
02:34:10,309 --> 02:34:08,939
she is the the deputy commissioning

3251
02:34:12,110 --> 02:34:10,319
engineer for the James Webb Space

3252
02:34:14,630 --> 02:34:12,120
Telescope and I am Michelle Fowler

3253
02:34:16,070 --> 02:34:14,640
you're we're joining you from uh the

3254
02:34:17,450 --> 02:34:16,080
Space Telescope Science Institute today

3255
02:34:19,849 --> 02:34:17,460
in Baltimore Maryland

3256
02:34:22,250 --> 02:34:19,859
and uh earlier in the day we

3257
02:34:24,290 --> 02:34:22,260
successfully deployed the wing the final

3258
02:34:25,429 --> 02:34:24,300
wing of the primary mirror and what's

3259
02:34:27,230 --> 02:34:25,439
going to be happening for the next

3260
02:34:30,290 --> 02:34:27,240
couple of hours is latching that into

3261
02:34:32,570 --> 02:34:30,300
place now uh during our broadcast you'll

3262
02:34:34,610 --> 02:34:32,580
probably see us pause as we listen to

3263
02:34:37,250 --> 02:34:34,620
commentary from the mock or the mission

3264
02:34:39,110 --> 02:34:37,260
operations center here so if we're

3265
02:34:41,510 --> 02:34:39,120
causing vid conversation we will start

3266
02:34:43,849 --> 02:34:41,520
right back up as soon as we get the call

3267
02:34:45,349 --> 02:34:43,859
and of course we're operating under some

3268
02:34:47,990 --> 02:34:45,359
very interesting circumstances today

3269
02:34:50,210 --> 02:34:48,000
because of the uh the The covid Surge we

3270
02:34:51,710 --> 02:34:50,220
were all isolated I'm downstairs in a

3271
02:34:53,990 --> 02:34:51,720
conference room so I can speak to you

3272
02:34:56,690 --> 02:34:54,000
without a mask on and Julie is in a room

3273
02:34:58,610 --> 02:34:56,700
upstairs so we're all isolated from each

3274
02:35:00,050 --> 02:34:58,620
other to keep each other safe you'll

3275
02:35:03,410 --> 02:35:00,060
notice that everybody is masked inside

3276
02:35:04,849 --> 02:35:03,420
the control room uh we had a uh a large

3277
02:35:06,110 --> 02:35:04,859
and beautiful set at Goddard space

3278
02:35:07,910 --> 02:35:06,120
flight center that we were going to do

3279
02:35:09,950 --> 02:35:07,920
perhaps a much more polished and

3280
02:35:11,929 --> 02:35:09,960
professional looking broadcast but in a

3281
02:35:13,849 --> 02:35:11,939
way this is kind of wonderful because it

3282
02:35:16,309 --> 02:35:13,859
was so important for us to bring you all

3283
02:35:18,110 --> 02:35:16,319
along on this very historic day this is

3284
02:35:20,389 --> 02:35:18,120
the the largest most complex space

3285
02:35:22,309 --> 02:35:20,399
Observatory ever built it's built to

3286
02:35:24,950 --> 02:35:22,319
answer some incredible questions about

3287
02:35:27,469 --> 02:35:24,960
the origins of stars and galaxies and

3288
02:35:29,090 --> 02:35:27,479
planets the origins of us uh the

3289
02:35:30,770 --> 02:35:29,100
possibility of there being environments

3290
02:35:33,650 --> 02:35:30,780
like the Earth on planets around other

3291
02:35:36,410 --> 02:35:33,660
stars and many many things in between

3292
02:35:38,330 --> 02:35:36,420
so the the rocket was launched carrying

3293
02:35:40,670 --> 02:35:38,340
the James Webb Space Telescope on

3294
02:35:43,370 --> 02:35:40,680
December 25th from French Guiana from

3295
02:35:46,130 --> 02:35:43,380
Peru that's in South America it's now

3296
02:35:48,290 --> 02:35:46,140
traveled more than 600 000 miles on its

3297
02:35:50,750 --> 02:35:48,300
way out to its final resting place at L2

3298
02:35:52,610 --> 02:35:50,760
L2 is a LaGrange point which is a

3299
02:35:54,110 --> 02:35:52,620
balance point between the gravity of the

3300
02:35:56,270 --> 02:35:54,120
Earth and the Sun that's a wonderful

3301
02:35:59,030 --> 02:35:56,280
stable place to put in Observatory web

3302
02:36:01,610 --> 02:35:59,040
is on it's way out there right now but

3303
02:36:03,770 --> 02:36:01,620
as it does so it is unfolding it's the

3304
02:36:05,929 --> 02:36:03,780
observatory is so large had to be folded

3305
02:36:07,910 --> 02:36:05,939
up to fit inside the rocket and that's

3306
02:36:09,349 --> 02:36:07,920
uh that's a unique thing about web that

3307
02:36:11,389 --> 02:36:09,359
has not been attempted before this

3308
02:36:13,370 --> 02:36:11,399
degree of unfolding and commissioning

3309
02:36:15,710 --> 02:36:13,380
and that's why we wanted to bring this

3310
02:36:18,230 --> 02:36:15,720
to you live because this is a live

3311
02:36:20,929 --> 02:36:18,240
broadcast based on an actual engineering

3312
02:36:22,969 --> 02:36:20,939
event the schedule is not known uh to

3313
02:36:25,130 --> 02:36:22,979
the minute the engineers will call out

3314
02:36:27,050 --> 02:36:25,140
the commands you know as they see fit

3315
02:36:30,650 --> 02:36:27,060
and at the pace that they want to go at

3316
02:36:33,590 --> 02:36:30,660
so this is a a broadcast that is not

3317
02:36:35,510 --> 02:36:33,600
only live but sort of you know very much

3318
02:36:37,730 --> 02:36:35,520
of the moment as we wait to see which

3319
02:36:39,950 --> 02:36:37,740
commands come in and how long they

3320
02:36:42,050 --> 02:36:39,960
decide to take from each step but but

3321
02:36:43,790 --> 02:36:42,060
Julie I I think you can um you can

3322
02:36:45,349 --> 02:36:43,800
reiterate everybody that things are

3323
02:36:48,650 --> 02:36:45,359
going very well this morning so far

3324
02:36:55,190 --> 02:36:51,950
yes so far our

3325
02:36:58,250 --> 02:36:55,200
actual motion of the mirrors segments as

3326
02:37:00,469 --> 02:36:58,260
they folded from being back alongside of

3327
02:37:02,870 --> 02:37:00,479
the structure to its final position as

3328
02:37:06,050 --> 02:37:02,880
you see it now in our visualization Tool

3329
02:37:08,870 --> 02:37:06,060
uh went extremely well uh the the motors

3330
02:37:11,570 --> 02:37:08,880
work perfectly the uh the launch

3331
02:37:13,070 --> 02:37:11,580
releases before that went perfectly and

3332
02:37:15,530 --> 02:37:13,080
uh now they're in the process of

3333
02:37:18,770 --> 02:37:15,540
latching into their final position so

3334
02:37:21,530 --> 02:37:18,780
that those mirrors are are aligned and

3335
02:37:26,389 --> 02:37:21,540
ready for the next steps which Leanne

3336
02:37:29,090 --> 02:37:27,710
so I'm just looking at some of the

3337
02:37:30,290 --> 02:37:29,100
social media questions that are coming

3338
02:37:31,490 --> 02:37:30,300
in and there's there's a lot of

3339
02:37:33,770 --> 02:37:31,500
different ones on the mirrors actually

3340
02:37:35,990 --> 02:37:33,780
this is probably one that we can answer

3341
02:37:38,090 --> 02:37:36,000
um so it's uh it's uh Jemison on Twitter

3342
02:37:40,429 --> 02:37:38,100
States my eight-year-old son wants to

3343
02:37:42,410 --> 02:37:40,439
know why the mirror is a set of hexagons

3344
02:37:44,210 --> 02:37:42,420
why why was that why was that shape

3345
02:37:46,010 --> 02:37:44,220
chosen for the mirror Julie you can

3346
02:37:48,590 --> 02:37:46,020
probably answer that one

3347
02:37:51,349 --> 02:37:48,600
as chores as you can kind of see in the

3348
02:37:54,590 --> 02:37:51,359
picture the hexagon shape uh packs in

3349
02:37:56,990 --> 02:37:54,600
nicely into a circle uh you know uh most

3350
02:38:00,050 --> 02:37:57,000
most telescopes you can

3351
02:38:02,870 --> 02:38:00,060
buy in the store or anywhere that you've

3352
02:38:06,530 --> 02:38:02,880
seen typically in in movies or whatnot

3353
02:38:08,090 --> 02:38:06,540
is um has a round mirror it gives you

3354
02:38:11,990 --> 02:38:08,100
the the best

3355
02:38:14,809 --> 02:38:12,000
um amount of light collected per per use

3356
02:38:16,090 --> 02:38:14,819
it it gives you a nice usable beam the

3357
02:38:18,469 --> 02:38:16,100
hexagon

3358
02:38:21,230 --> 02:38:18,479
approximated that very closely it has a

3359
02:38:24,530 --> 02:38:21,240
nice packing shape you can see how it um

3360
02:38:27,590 --> 02:38:24,540
fits in around the Optics that that kind

3361
02:38:30,050 --> 02:38:27,600
of poke out that nose in the middle is

3362
02:38:32,630 --> 02:38:30,060
um is called the AFT Optics it's the

3363
02:38:33,889 --> 02:38:32,640
Optics that kind of fold the beam a

3364
02:38:37,070 --> 02:38:33,899
couple times before it sends it back

3365
02:38:39,469 --> 02:38:37,080
into the science instruments the

3366
02:38:43,670 --> 02:38:39,479
the outside shape of the mirror itself

3367
02:38:47,929 --> 02:38:43,680
it doesn't matter as much of each of the

3368
02:38:50,210 --> 02:38:47,939
uh edges of those those mirrors are very

3369
02:38:52,910 --> 02:38:50,220
carefully handled to make sure that they

3370
02:38:56,090 --> 02:38:52,920
don't have glints off the edges uh and

3371
02:38:59,210 --> 02:38:56,100
to make sure that the uh the the edges

3372
02:39:01,250 --> 02:38:59,220
are perfectly uh handled with how the

3373
02:39:04,130 --> 02:39:01,260
gold coating reaches the edges of those

3374
02:39:04,849 --> 02:39:04,140
so the the

3375
02:39:07,250 --> 02:39:04,859
um

3376
02:39:09,410 --> 02:39:07,260
the hexagon gave us a great shape for

3377
02:39:11,690 --> 02:39:09,420
handling the mirror in its movement the

3378
02:39:15,050 --> 02:39:11,700
way that Lee had described and it gave

3379
02:39:17,870 --> 02:39:15,060
us the best approximation of round

3380
02:39:19,010 --> 02:39:17,880
okay and it's worth mentioning we've got

3381
02:39:20,630 --> 02:39:19,020
a couple different questions about the

3382
02:39:22,250 --> 02:39:20,640
gold coating that we're just going to

3383
02:39:25,010 --> 02:39:22,260
pause see what they're saying in the

3384
02:39:30,410 --> 02:39:28,070
go ahead this is

3385
02:39:31,969 --> 02:39:30,420
um so at this time I can really confirm

3386
02:39:34,910 --> 02:39:31,979
that definitely just ready to begin the

3387
02:39:39,290 --> 02:39:34,920
three door a couple hatch to full and

3388
02:39:44,150 --> 02:39:42,230
copia and that command line looks good

3389
02:39:46,130 --> 02:39:44,160
you're going to execute

3390
02:39:50,570 --> 02:39:46,140
talking

3391
02:39:52,969 --> 02:39:50,580
to see how they go to Circuit executed

3392
02:39:56,809 --> 02:39:52,979
and you're going to continue

3393
02:39:56,819 --> 02:40:07,610
nice to see you smile there Julie

3394
02:40:11,450 --> 02:40:09,530
not at all

3395
02:40:13,250 --> 02:40:11,460
let's say we're actually right now in

3396
02:40:15,230 --> 02:40:13,260
the latching procedure this will take a

3397
02:40:17,030 --> 02:40:15,240
couple of hours as the uh the mirror was

3398
02:40:19,490 --> 02:40:17,040
moved this morning and now it's being

3399
02:40:20,690 --> 02:40:19,500
latched into its its final place

3400
02:40:23,030 --> 02:40:20,700
that there are a couple different

3401
02:40:25,490 --> 02:40:23,040
questions on how we design things to

3402
02:40:28,550 --> 02:40:25,500
operate at this you know very very low

3403
02:40:29,450 --> 02:40:28,560
uh temperature in fact um I mean this

3404
02:40:31,190 --> 02:40:29,460
may be something that you as a

3405
02:40:33,170 --> 02:40:31,200
mechanical engineer so so Jerry from

3406
02:40:34,730 --> 02:40:33,180
Twitter asked what kind of lubricants

3407
02:40:36,769 --> 02:40:34,740
are required for the bearings or the

3408
02:40:38,690 --> 02:40:36,779
wing segments and mirrors or there or

3409
02:40:39,950 --> 02:40:38,700
are they electrically heated in the way

3410
02:40:42,469 --> 02:40:39,960
that they can actually you know move

3411
02:40:44,389 --> 02:40:42,479
around at these very low temperatures

3412
02:40:46,670 --> 02:40:44,399
like you said I mean not much more than

3413
02:40:48,590 --> 02:40:46,680
you know 100 degrees above absolute zero

3414
02:40:50,510 --> 02:40:48,600
can you give us a sense about about how

3415
02:40:52,550 --> 02:40:50,520
you design an actuator to actually move

3416
02:40:56,170 --> 02:40:52,560
and function you know things to actually

3417
02:40:59,030 --> 02:40:56,180
swing around that when they're that cold

3418
02:41:01,190 --> 02:40:59,040
that's a great question and it's been

3419
02:41:04,570 --> 02:41:01,200
one of our major challenges

3420
02:41:12,830 --> 02:41:04,580
um as you heard a little bit about that

3421
02:41:17,809 --> 02:41:16,429
that the uh

3422
02:41:19,910 --> 02:41:17,819
the

3423
02:41:21,469 --> 02:41:19,920
uh

3424
02:41:25,570 --> 02:41:21,479
I'm sorry I lost my chain of thought

3425
02:41:32,330 --> 02:41:28,730
but uh when Lee was talking about the

3426
02:41:34,370 --> 02:41:32,340
the ears swinging into position

3427
02:41:36,950 --> 02:41:34,380
um they have a particular type of Lube

3428
02:41:39,110 --> 02:41:36,960
on it we did heat these particular ones

3429
02:41:42,170 --> 02:41:39,120
up because they are what is called a wet

3430
02:41:44,809 --> 02:41:42,180
Lube um which means that we want them to

3431
02:41:46,250 --> 02:41:44,819
be at a special temperature many many of

3432
02:41:48,110 --> 02:41:46,260
our other actuators are the ones that

3433
02:41:50,690 --> 02:41:48,120
they was talking about that on the backs

3434
02:41:53,269 --> 02:41:50,700
of the mirrors and lots of other places

3435
02:41:55,610 --> 02:41:53,279
throughout the telescope

3436
02:41:58,550 --> 02:41:55,620
uh called what is a

3437
02:42:01,429 --> 02:41:58,560
a dry lube and most of the time the dry

3438
02:42:04,130 --> 02:42:01,439
lube that's used is a molybden uh

3439
02:42:07,070 --> 02:42:04,140
disulfide and it's this um it's

3440
02:42:08,690 --> 02:42:07,080
essentially a very very soft material

3441
02:42:12,830 --> 02:42:08,700
that um

3442
02:42:15,410 --> 02:42:12,840
is uh is is not uh

3443
02:42:17,570 --> 02:42:15,420
a liquid at all it's actually a solid

3444
02:42:20,450 --> 02:42:17,580
material that gets coated onto the

3445
02:42:22,190 --> 02:42:20,460
surface of a of a joint and the the

3446
02:42:26,510 --> 02:42:22,200
surface of the joint kind of smears

3447
02:42:27,950 --> 02:42:26,520
across that soft metal and and uh has a

3448
02:42:31,969 --> 02:42:27,960
very low friction

3449
02:42:35,570 --> 02:42:31,979
it's interesting uh because we're using

3450
02:42:37,910 --> 02:42:35,580
it at such low temperatures and

3451
02:42:39,410 --> 02:42:37,920
um as as we've talked about before there

3452
02:42:41,809 --> 02:42:39,420
was such a long period of time in

3453
02:42:43,309 --> 02:42:41,819
designing and building web so one of the

3454
02:42:46,250 --> 02:42:43,319
major things that we had to go through

3455
02:42:49,309 --> 02:42:46,260
was a lifetime test and in our lifetime

3456
02:42:53,090 --> 02:42:49,319
tests it's very difficult to simulate

3457
02:42:56,630 --> 02:42:53,100
exactly how long you're going to be in

3458
02:42:58,490 --> 02:42:56,640
and testing the ground so if you want to

3459
02:43:03,050 --> 02:42:58,500
say that your mechanism is going to be

3460
02:43:06,650 --> 02:43:03,060
good you know from the day we coat our

3461
02:43:08,750 --> 02:43:06,660
um our our joint to the day that we're

3462
02:43:11,210 --> 02:43:08,760
finished using it on orbit and maybe

3463
02:43:13,910 --> 02:43:11,220
that's a period of of 10 years maybe

3464
02:43:16,730 --> 02:43:13,920
that's a period of 20 years maybe we've

3465
02:43:18,769 --> 02:43:16,740
got you know lots of fuel and we we get

3466
02:43:20,750 --> 02:43:18,779
to do it for 30 years how do you get to

3467
02:43:22,269 --> 02:43:20,760
qualify that

3468
02:43:25,370 --> 02:43:22,279
um

3469
02:43:32,750 --> 02:43:25,380
transition to Mattress in an hour and 10

3470
02:43:37,969 --> 02:43:35,030
in a way might be actually the simplest

3471
02:43:39,889 --> 02:43:37,979
part of it uh it's steady state it's

3472
02:43:42,349 --> 02:43:39,899
always uh set steady state temperature

3473
02:43:45,050 --> 02:43:42,359
it's always a cryogenic temperature it

3474
02:43:47,570 --> 02:43:45,060
doesn't come back to error uh it's never

3475
02:43:51,290 --> 02:43:47,580
exposed to oxygen again oxygen is one of

3476
02:43:54,710 --> 02:43:51,300
the things that can degrade surfaces it

3477
02:43:57,650 --> 02:43:54,720
oxidizes creates little little uh chunky

3478
02:43:59,269 --> 02:43:57,660
pieces of oxidation so once we're in

3479
02:44:00,769 --> 02:43:59,279
orbit like we're pretty good with this

3480
02:44:04,250 --> 02:44:00,779
the

3481
02:44:06,469 --> 02:44:04,260
out well how many times are we going to

3482
02:44:07,849 --> 02:44:06,479
move this mechanism in air how many

3483
02:44:09,170 --> 02:44:07,859
times we're going to use it in vacuum

3484
02:44:11,150 --> 02:44:09,180
how many times we're going to use it at

3485
02:44:14,030 --> 02:44:11,160
cryogenic temperatures all through our

3486
02:44:14,990 --> 02:44:14,040
testing Lifetime and then put on top of

3487
02:44:17,809 --> 02:44:15,000
that

3488
02:44:20,090 --> 02:44:17,819
how long is it going to be used in space

3489
02:44:22,190 --> 02:44:20,100
in those conditions and will it have

3490
02:44:24,710 --> 02:44:22,200
enough life of that joint

3491
02:44:26,750 --> 02:44:24,720
so that was a great question

3492
02:44:29,510 --> 02:44:26,760
yeah absolutely I mean I mean this is

3493
02:44:30,710 --> 02:44:29,520
part of this idea of cryoengineering you

3494
02:44:32,929 --> 02:44:30,720
know but making things that are going to

3495
02:44:34,790 --> 02:44:32,939
be work and work for a long time and

3496
02:44:36,950 --> 02:44:34,800
work reliably under these sorts of

3497
02:44:38,090 --> 02:44:36,960
temperatures and and actually there

3498
02:44:39,650 --> 02:44:38,100
there are you know there are more

3499
02:44:41,870 --> 02:44:39,660
questions coming in from social media

3500
02:44:43,670 --> 02:44:41,880
about you know like for example uh

3501
02:44:45,290 --> 02:44:43,680
Dorian on Twitch said how did you manage

3502
02:44:47,389 --> 02:44:45,300
to test the focusing of the mirrors on

3503
02:44:48,830 --> 02:44:47,399
Earth with all the deformations so we've

3504
02:44:51,710 --> 02:44:48,840
mentioned that it's you know it's not

3505
02:44:53,870 --> 02:44:51,720
just uh you know one of the deformations

3506
02:44:55,670 --> 02:44:53,880
is caused by gravity versus no gravity

3507
02:44:57,469 --> 02:44:55,680
but there's also the deformations caused

3508
02:44:58,969 --> 02:44:57,479
by temperature and and this is something

3509
02:45:01,250 --> 02:44:58,979
that you know I've had the pleasure of

3510
02:45:03,710 --> 02:45:01,260
being able to watch for the last years

3511
02:45:05,929 --> 02:45:03,720
is all of the different stages of

3512
02:45:07,370 --> 02:45:05,939
testing of this uh maybe you can talk a

3513
02:45:09,050 --> 02:45:07,380
bit about some of the cryo tests that

3514
02:45:10,670 --> 02:45:09,060
this uh that this telescope had to go

3515
02:45:12,170 --> 02:45:10,680
through

3516
02:45:15,170 --> 02:45:12,180
sure

3517
02:45:17,929 --> 02:45:15,180
um you know the way NASA approaches this

3518
02:45:20,870 --> 02:45:17,939
and all the contractors that work for us

3519
02:45:22,849 --> 02:45:20,880
and and uh Isa too and their nominal

3520
02:45:25,250 --> 02:45:22,859
test program is you start at like the

3521
02:45:28,070 --> 02:45:25,260
very most basic level uh you saw some of

3522
02:45:30,950 --> 02:45:28,080
the the pictures of the mirrors being uh

3523
02:45:32,389 --> 02:45:30,960
uh built and assembled and Lee talked a

3524
02:45:35,210 --> 02:45:32,399
little bit about their manufacturer

3525
02:45:37,730 --> 02:45:35,220
along the way well that happens with

3526
02:45:41,510 --> 02:45:37,740
every component is you start at like the

3527
02:45:44,929 --> 02:45:41,520
component level like the piece parts and

3528
02:45:47,450 --> 02:45:44,939
you um you started testing them and

3529
02:45:49,250 --> 02:45:47,460
understanding them and even at cryogenic

3530
02:45:52,010 --> 02:45:49,260
temperatures you might start off with

3531
02:45:55,070 --> 02:45:52,020
just doing cryo Cycles to make sure that

3532
02:46:06,110 --> 02:45:55,080
those standby

3533
02:46:10,809 --> 02:46:08,450
so there's positive conversations we

3534
02:46:12,950 --> 02:46:10,819
listen to the Box yes

3535
02:46:15,170 --> 02:46:12,960
sometimes I get more conversation about

3536
02:46:17,570 --> 02:46:15,180
you and from the deaf lead um if happy

3537
02:46:20,510 --> 02:46:17,580
with the two-door latch to fall already

3538
02:46:22,670 --> 02:46:20,520
continue with the three door

3539
02:46:24,469 --> 02:46:22,680
oh sorry we're he was happy with the

3540
02:46:26,269 --> 02:46:24,479
three door latch to full we're ready to

3541
02:46:30,530 --> 02:46:26,279
continue with the two-door latch to full

3542
02:46:34,610 --> 02:46:30,540
and that is motor move 14 of 20.

3543
02:46:40,670 --> 02:46:37,010
and that command line looks good you are

3544
02:46:43,790 --> 02:46:40,680
going to execute okay

3545
02:46:50,150 --> 02:46:45,429
and you're gonna continue

3546
02:46:55,190 --> 02:46:52,010
so just to wrap up our conversation on

3547
02:46:58,969 --> 02:46:55,200
on cryo testing like some materials like

3548
02:47:01,370 --> 02:46:58,979
specifically are are carbon tube

3549
02:47:03,050 --> 02:47:01,380
material that you you could see in our

3550
02:47:05,090 --> 02:47:03,060
current visualization with the tubes

3551
02:47:06,889 --> 02:47:05,100
that hang the secondary mirror out in

3552
02:47:10,070 --> 02:47:06,899
front of us are all of our backplane

3553
02:47:13,510 --> 02:47:10,080
materials they're made of a carbon

3554
02:47:16,990 --> 02:47:13,520
structure that has a cyanate uh

3555
02:47:21,070 --> 02:47:19,250
polymer that binds all those carbons

3556
02:47:24,469 --> 02:47:21,080
together and that's like a special

3557
02:47:26,870 --> 02:47:24,479
polymer that's designed for high

3558
02:47:30,650 --> 02:47:26,880
stability at cryogenic temperatures but

3559
02:47:33,830 --> 02:47:30,660
in order to deal with that parameters

3560
02:47:37,130 --> 02:47:33,840
and know it at a higher temperature

3561
02:47:39,290 --> 02:47:37,140
you have to go through a Cycles to kind

3562
02:47:41,389 --> 02:47:39,300
of cryo stress relieve it and the

3563
02:47:43,910 --> 02:47:41,399
mirrors had the same thing so there's

3564
02:47:46,010 --> 02:47:43,920
lots of stuff that we do early on to to

3565
02:47:47,170 --> 02:47:46,020
help these materials deal with that cry

3566
02:47:49,610 --> 02:47:47,180
death

3567
02:47:56,929 --> 02:47:49,620
cryogenic temperature

3568
02:48:03,889 --> 02:48:00,730
project so they're in their final stages

3569
02:48:06,230 --> 02:48:03,899
of uh moving each of these latches into

3570
02:48:08,630 --> 02:48:06,240
their full position so they get their

3571
02:48:11,809 --> 02:48:08,640
full load on them and this will this

3572
02:48:14,090 --> 02:48:11,819
will um be the be the final thing that

3573
02:48:16,730 --> 02:48:14,100
holds that mirror down we did this with

3574
02:48:18,530 --> 02:48:16,740
the other side yesterday once it's in

3575
02:48:20,990 --> 02:48:18,540
its final position we've never touched

3576
02:48:22,730 --> 02:48:21,000
these latches again every motion from

3577
02:48:24,710 --> 02:48:22,740
that point forward is happening at the

3578
02:48:26,990 --> 02:48:24,720
mechanism level that's behind each of

3579
02:48:29,809 --> 02:48:27,000
the mirrors and not at the frame and the

3580
02:48:33,230 --> 02:48:29,819
structure uh behind it that we're

3581
02:48:34,910 --> 02:48:33,240
latching into position today

3582
02:48:36,290 --> 02:48:34,920
well Julie thank you so much for joining

3583
02:48:37,250 --> 02:48:36,300
us hopefully we I think we'll have a

3584
02:48:39,830 --> 02:48:37,260
chance to talk to you a little bit later

3585
02:48:41,330 --> 02:48:39,840
in the broadcast uh for those of you

3586
02:48:43,309 --> 02:48:41,340
that are just joining us you're watching

3587
02:48:46,510 --> 02:48:43,319
the live commissioning of the James Webb

3588
02:48:49,610 --> 02:48:46,520
Space Telescope okay and uh

3589
02:48:51,590 --> 02:48:49,620
be advised at this time we have just

3590
02:48:53,450 --> 02:48:51,600
about uh just a little more than an hour

3591
02:48:56,690 --> 02:48:53,460
before we begin our activities to hand

3592
02:49:00,050 --> 02:48:56,700
over from BSN Canberra to DSN Madrid

3593
02:49:01,969 --> 02:49:00,060
that will start at 18 15 when we will

3594
02:49:04,130 --> 02:49:01,979
lose coverage on the Madrid backup

3595
02:49:07,190 --> 02:49:04,140
station or remember a backup station

3596
02:49:09,650 --> 02:49:07,200
excuse me pss36 we will have command and

3597
02:49:11,389 --> 02:49:09,660
Telemetry through Canberra Prime dss34

3598
02:49:14,570 --> 02:49:11,399
for another five minutes

3599
02:49:16,550 --> 02:49:14,580
at 1820 Canberra Prime will bring down

3600
02:49:18,769 --> 02:49:16,560
their Uplink and we will have single

3601
02:49:22,550 --> 02:49:18,779
antenna Telemetry only at Canberra for

3602
02:49:25,730 --> 02:49:22,560
another five minutes at 1825 Canberra

3603
02:49:28,130 --> 02:49:25,740
will end their track Madrid Prime dss54

3604
02:49:30,110 --> 02:49:28,140
will start their track

3605
02:49:33,710 --> 02:49:30,120
then bring up the Uplink as soon as they

3606
02:49:40,250 --> 02:49:37,490
and at 18 35 minutes later our Madrid

3607
02:49:42,830 --> 02:49:40,260
backup station dss56 will acquire the

3608
02:49:46,429 --> 02:49:42,840
downlines so to reiterate we will lose

3609
02:49:48,170 --> 02:49:46,439
back up to Lem at 1815 lose command at

3610
02:49:51,769 --> 02:49:48,180
18 20.

3611
02:49:54,290 --> 02:49:51,779
get command back at 1825 and get back up

3612
02:49:56,090 --> 02:49:54,300
to Lem back at 18 30. uh there will be

3613
02:49:57,769 --> 02:49:56,100
continuous Telemetry despite the

3614
02:49:59,630 --> 02:49:57,779
five-minute command outage except for a

3615
02:50:01,730 --> 02:49:59,640
few interruptions I will call them out

3616
02:50:06,530 --> 02:50:01,740
before they occur

3617
02:50:10,070 --> 02:50:07,790
once again thank you for joining us

3618
02:50:13,250 --> 02:50:11,750
all right so we're listening to uh live

3619
02:50:14,750 --> 02:50:13,260
commands from the mission operations

3620
02:50:16,910 --> 02:50:14,760
center at the Space Telescope Science

3621
02:50:18,469 --> 02:50:16,920
Institute in Baltimore Maryland I'm

3622
02:50:19,610 --> 02:50:18,479
Michelle Thaller for anybody just

3623
02:50:22,610 --> 02:50:19,620
joining us you're watching live

3624
02:50:24,170 --> 02:50:22,620
commissioning we'll see you guys at this

3625
02:50:26,389 --> 02:50:24,180
time you have one hour of command

3626
02:50:29,330 --> 02:50:26,399
remaining on DSM Canberra

3627
02:50:30,769 --> 02:50:29,340
copia would you would you hear them

3628
02:50:33,530 --> 02:50:30,779
talking about is something called the

3629
02:50:34,790 --> 02:50:33,540
deep space Network the DSi the way that

3630
02:50:38,269 --> 02:50:34,800
web

3631
02:50:40,790 --> 02:50:38,279
Earth is that there are several large uh

3632
02:50:42,830 --> 02:50:40,800
antennas radio dishes around the world

3633
02:50:44,389 --> 02:50:42,840
and of course as the Earth turns

3634
02:50:45,830 --> 02:50:44,399
different ones different different

3635
02:50:47,630 --> 02:50:45,840
different dishes come into view and out

3636
02:50:49,910 --> 02:50:47,640
of view of the web telescope the web

3637
02:50:51,710 --> 02:50:49,920
telescope itself is now uh more than

3638
02:50:54,710 --> 02:50:51,720
twice as far away as the moon it's about

3639
02:50:57,230 --> 02:50:54,720
600 000 miles away today and it's going

3640
02:50:59,210 --> 02:50:57,240
out to about a million miles away a

3641
02:51:00,769 --> 02:50:59,220
point called L2 the LaGrange point a

3642
02:51:02,510 --> 02:51:00,779
balance between the gravity of Earth and

3643
02:51:04,730 --> 02:51:02,520
the Earth and the Sun a wonderful place

3644
02:51:06,230 --> 02:51:04,740
to park a telescope for the long and

3645
02:51:08,510 --> 02:51:06,240
hopefully very successful Mission ahead

3646
02:51:11,210 --> 02:51:08,520
of it it's been an absolutely incredible

3647
02:51:13,849 --> 02:51:11,220
journey uh the uh the James Webb Space

3648
02:51:16,309 --> 02:51:13,859
Telescope launched on December 25th from

3649
02:51:18,110 --> 02:51:16,319
French Guiana from Coro this is the main

3650
02:51:19,670 --> 02:51:18,120
launch site of the European Space Agency

3651
02:51:21,950 --> 02:51:19,680
one of the major Partners in the James

3652
02:51:23,510 --> 02:51:21,960
Webb Space Telescope other major

3653
02:51:26,990 --> 02:51:23,520
Partners include the Canadian space

3654
02:51:28,610 --> 02:51:27,000
agency and of course NASA and uh the uh

3655
02:51:31,610 --> 02:51:28,620
the telescope has been on an incredible

3656
02:51:33,050 --> 02:51:31,620
journey I have been honored to have been

3657
02:51:34,550 --> 02:51:33,060
working in government at least in there

3658
02:51:36,410 --> 02:51:34,560
while much of it was built so I was able

3659
02:51:38,570 --> 02:51:36,420
to see some of the testing and something

3660
02:51:40,910 --> 02:51:38,580
of the primary mirror as well as the

3661
02:51:42,590 --> 02:51:40,920
instrument package and and then it was

3662
02:51:45,469 --> 02:51:42,600
shipped to north of Grumman in

3663
02:51:48,530 --> 02:51:45,479
California where it was uh actually put

3664
02:51:50,090 --> 02:51:48,540
onto the um uh the the actual spacecraft

3665
02:51:52,130 --> 02:51:50,100
and you see here some of the the

3666
02:51:53,870 --> 02:51:52,140
integration you see that large primary

3667
02:51:56,690 --> 02:51:53,880
mirror and that's exactly what happened

3668
02:51:58,250 --> 02:51:56,700
earlier today is that the final Wing was

3669
02:52:00,349 --> 02:51:58,260
deployed so we now have the full

3670
02:52:02,150 --> 02:52:00,359
complete mirror uh deployed and it's now

3671
02:52:03,830 --> 02:52:02,160
being lashed into place what you see

3672
02:52:06,710 --> 02:52:03,840
here is the testing of the incredible

3673
02:52:09,230 --> 02:52:06,720
sun shield this is a five layer shield

3674
02:52:11,690 --> 02:52:09,240
made of Captain a very light a very

3675
02:52:13,550 --> 02:52:11,700
strong material each one of those layers

3676
02:52:15,230 --> 02:52:13,560
makes the layer above it a little bit

3677
02:52:16,730 --> 02:52:15,240
colder until you finally get up to the

3678
02:52:19,250 --> 02:52:16,740
telescope that has an operating

3679
02:52:22,190 --> 02:52:19,260
temperature of under 400 Degrees my

3680
02:52:24,769 --> 02:52:22,200
under minus 400 degrees Fahrenheit so uh

3681
02:52:26,450 --> 02:52:24,779
just an incredible Marvel that was Julie

3682
02:52:28,010 --> 02:52:26,460
van kampen who was talking to us a bit

3683
02:52:29,570 --> 02:52:28,020
about some of the testing that was

3684
02:52:31,250 --> 02:52:29,580
required to make sure that different

3685
02:52:33,050 --> 02:52:31,260
components actually worked at that

3686
02:52:35,090 --> 02:52:33,060
incredible temperature

3687
02:52:37,490 --> 02:52:35,100
so here you see a beautiful picture of

3688
02:52:40,190 --> 02:52:37,500
that large primary mirror the mirror

3689
02:52:42,349 --> 02:52:40,200
segments are each each one of those

3690
02:52:44,690 --> 02:52:42,359
mirror segments is a bit over a meter uh

3691
02:52:46,790 --> 02:52:44,700
in in length so the mirror itself is

3692
02:52:48,349 --> 02:52:46,800
about a little bit over a little bit

3693
02:52:50,269 --> 02:52:48,359
over seven meters about seven and a half

3694
02:52:52,730 --> 02:52:50,279
meters across which is absolutely

3695
02:52:54,889 --> 02:52:52,740
incredible a long journey to get it here

3696
02:52:56,750 --> 02:52:54,899
from Goddard space flight center uh the

3697
02:52:59,090 --> 02:52:56,760
different universities where instruments

3698
02:53:00,950 --> 02:52:59,100
were built to uh north of Grumman where

3699
02:53:03,050 --> 02:53:00,960
it was all put together and and finally

3700
02:53:05,570 --> 02:53:03,060
tested and then put on a boat through

3701
02:53:07,550 --> 02:53:05,580
the Panama Canal and to uh to Kuro and

3702
02:53:16,010 --> 02:53:07,560
then the European space agency's launch

3703
02:53:20,150 --> 02:53:18,290
you'll uh you'll hear me pausing in the

3704
02:53:22,130 --> 02:53:20,160
commentary just so we can listen to what

3705
02:53:23,990 --> 02:53:22,140
the commands are currently they are

3706
02:53:27,110 --> 02:53:24,000
latching the telescope into its final

3707
02:53:30,650 --> 02:53:27,120
place and uh it's been an amazing

3708
02:53:33,110 --> 02:53:30,660
continue with the matter move

3709
02:53:34,910 --> 02:53:33,120
to continue

3710
02:53:36,889 --> 02:53:34,920
Roger the first thing that happened

3711
02:53:38,990 --> 02:53:36,899
about a week ago was the deployment of

3712
02:53:41,269 --> 02:53:39,000
the sun shield that was a very dramatic

3713
02:53:43,910 --> 02:53:41,279
and incredible and then came the the

3714
02:53:46,250 --> 02:53:43,920
secondary mirror the secondary mirror is

3715
02:53:47,630 --> 02:53:46,260
on a large boom that has to come out in

3716
02:53:49,730 --> 02:53:47,640
front of the primary mirrors the

3717
02:53:51,349 --> 02:53:49,740
focusing mirror the light from all of

3718
02:53:53,330 --> 02:53:51,359
those wonderful gold coated mirror

3719
02:53:55,370 --> 02:53:53,340
segments they're all focused up to the

3720
02:53:56,929 --> 02:53:55,380
secondary mirror which then directs the

3721
02:53:58,849 --> 02:53:56,939
light down into the instrument packages

3722
02:54:00,290 --> 02:53:58,859
and you can see here some of the major

3723
02:54:02,090 --> 02:54:00,300
deployments that Webb has been through

3724
02:54:04,070 --> 02:54:02,100
the very first deployment which we

3725
02:54:06,349 --> 02:54:04,080
actually saw on cameras from the rocket

3726
02:54:08,510 --> 02:54:06,359
was the uh the the solar panels to power

3727
02:54:10,910 --> 02:54:08,520
up the spacecraft and here you see that

3728
02:54:13,010 --> 02:54:10,920
incredible sun shield uh being unfolded

3729
02:54:15,290 --> 02:54:13,020
so there are the front and back

3730
02:54:16,969 --> 02:54:15,300
components of the sun shield web was

3731
02:54:18,950 --> 02:54:16,979
then lifted away from the sun shield

3732
02:54:21,110 --> 02:54:18,960
where it will be isolated and cold

3733
02:54:23,630 --> 02:54:21,120
operating temperatures like I said near

3734
02:54:27,050 --> 02:54:23,640
minus 400 degrees Fahrenheit

3735
02:54:28,670 --> 02:54:27,060
and uh that was a a baffled actually uh

3736
02:54:30,590 --> 02:54:28,680
that was put up to help it helped steady

3737
02:54:32,450 --> 02:54:30,600
itself in the solar wind a wind of

3738
02:54:34,429 --> 02:54:32,460
particles from the Sun and now we're

3739
02:54:35,510 --> 02:54:34,439
going to see the deployment of the sun

3740
02:54:37,670 --> 02:54:35,520
shield

3741
02:54:39,469 --> 02:54:37,680
this of course is a computer animation

3742
02:54:40,490 --> 02:54:39,479
we did not have any cameras on web

3743
02:54:41,990 --> 02:54:40,500
itself

3744
02:54:44,690 --> 02:54:42,000
but uh one of the things that we've been

3745
02:54:47,690 --> 02:54:44,700
able to do today is uh see live

3746
02:54:48,889 --> 02:54:47,700
visualizations from data from Telemetry

3747
02:54:50,510 --> 02:54:48,899
that's been coming down from the

3748
02:54:52,370 --> 02:54:50,520
telescopes

3749
02:54:54,889 --> 02:54:52,380
so the telescope has been sending us

3750
02:54:57,110 --> 02:54:54,899
signals as to what configuration it's in

3751
02:54:59,030 --> 02:54:57,120
and we've been following that this

3752
02:55:00,650 --> 02:54:59,040
morning and of course that was one here

3753
02:55:02,510 --> 02:55:00,660
you see that secondary mirror coming out

3754
02:55:05,389 --> 02:55:02,520
on those long long booms

3755
02:55:07,849 --> 02:55:05,399
and then uh yesterday you'll see the

3756
02:55:09,710 --> 02:55:07,859
next thing that happens is is one of

3757
02:55:11,929 --> 02:55:09,720
these uh these mirror segments was

3758
02:55:14,870 --> 02:55:11,939
clicked into place that was the activity

3759
02:55:17,030 --> 02:55:14,880
yesterday and this morning the final uh

3760
02:55:18,650 --> 02:55:17,040
the final wing of the primary mirror is

3761
02:55:21,170 --> 02:55:18,660
in place

3762
02:55:23,809 --> 02:55:21,180
so we have a a very special guest uh

3763
02:55:26,210 --> 02:55:23,819
joining us uh next we have Greg Robinson

3764
02:55:27,889 --> 02:55:26,220
and uh there are a few different people

3765
02:55:29,269 --> 02:55:27,899
including Tom Mister bookend who had

3766
02:55:35,530 --> 02:55:29,279
mentioned Greg earlier in the broadcast

3767
02:55:40,670 --> 02:55:38,150
uh definitely have confirmed that the

3768
02:55:43,670 --> 02:55:40,680
latch off stove performed as expected

3769
02:55:49,690 --> 02:55:43,680
he's ready to continue to the top one

3770
02:55:54,650 --> 02:55:51,469
10x1 please

3771
02:56:04,730 --> 02:55:56,570
and Greg will continue with you as soon

3772
02:56:09,490 --> 02:56:06,769
thank you

3773
02:56:12,889 --> 02:56:09,500
I think we're good to go welcome Greg

3774
02:56:13,910 --> 02:56:12,899
Michelle glad to be here oh what what

3775
02:56:16,190 --> 02:56:13,920
wonderful to have you here

3776
02:56:18,230 --> 02:56:16,200
congratulations on this this very

3777
02:56:20,030 --> 02:56:18,240
successful and exciting morning how are

3778
02:56:22,370 --> 02:56:20,040
you feeling right now

3779
02:56:24,769 --> 02:56:22,380
I'm feeling pretty good uh this is

3780
02:56:27,830 --> 02:56:24,779
certainly a huge milestone to complete

3781
02:56:29,630 --> 02:56:27,840
the all of the deployments uh as you

3782
02:56:31,490 --> 02:56:29,640
know this was the stage where we thought

3783
02:56:33,650 --> 02:56:31,500
we had the most risk in the mission

3784
02:56:36,230 --> 02:56:33,660
still have a long ways to go

3785
02:56:37,969 --> 02:56:36,240
uh but certainly uh it's great to have

3786
02:56:41,870 --> 02:56:37,979
this part behind us

3787
02:56:46,309 --> 02:56:44,330
so uh tell us a bit about your role on

3788
02:56:48,950 --> 02:56:46,319
on the James Webb Space Telescope I know

3789
02:56:50,570 --> 02:56:48,960
no you you are at NASA headquarters and

3790
02:56:52,190 --> 02:56:50,580
and what what has been your role for the

3791
02:56:54,469 --> 02:56:52,200
larger mission

3792
02:56:57,530 --> 02:56:54,479
so I've been on the program four years

3793
02:57:00,349 --> 02:56:57,540
so I'm the baby uh my role as program

3794
02:57:04,490 --> 02:57:00,359
director is to provide oversight to the

3795
02:57:06,469 --> 02:57:04,500
project uh execution uh leadership going

3796
02:57:08,570 --> 02:57:06,479
up to the administrative level to what

3797
02:57:10,130 --> 02:57:08,580
we call the non-floor and external

3798
02:57:14,389 --> 02:57:10,140
without stakeholders

3799
02:57:18,530 --> 02:57:16,849
and uh people time and time again have

3800
02:57:20,269 --> 02:57:18,540
commented on what a wonderful team this

3801
02:57:22,190 --> 02:57:20,279
is you know can you give us some

3802
02:57:23,570 --> 02:57:22,200
observations and maybe maybe some

3803
02:57:25,010 --> 02:57:23,580
personal stories about just how well

3804
02:57:25,969 --> 02:57:25,020
this team has worked together and

3805
02:57:29,210 --> 02:57:25,979
there's some very challenging

3806
02:57:31,670 --> 02:57:29,220
circumstances stand by

3807
02:57:33,710 --> 02:57:31,680
Cinema

3808
02:57:35,750 --> 02:57:33,720
yeah this is certainly an amazing team

3809
02:57:37,550 --> 02:57:35,760
honestly I will interview this

3810
02:57:40,010 --> 02:57:37,560
parameters and they look good we are

3811
02:57:41,870 --> 02:57:40,020
going to continue with the better move

3812
02:57:44,389 --> 02:57:41,880
topical to continue

3813
02:57:46,610 --> 02:57:44,399
Roger

3814
02:57:49,990 --> 02:57:46,620
I'd love to hear the voices because that

3815
02:57:52,790 --> 02:57:50,000
means we're making creepy progress

3816
02:57:54,769 --> 02:57:52,800
yeah so uh you know a very large team

3817
02:57:57,950 --> 02:57:54,779
across the globe if you've mentioned

3818
02:57:59,630 --> 02:57:57,960
that and certainly a lot of you look at

3819
02:58:02,870 --> 02:57:59,640
leaders at different locations at

3820
02:58:05,210 --> 02:58:02,880
Goddard at Northrop Institute here and

3821
02:58:08,210 --> 02:58:05,220
across the entire industrial base in the

3822
02:58:10,550 --> 02:58:08,220
U.S and across the globe a really good

3823
02:58:13,130 --> 02:58:10,560
team uh certainly at headquarters uh at

3824
02:58:15,230 --> 02:58:13,140
Bond level and Thomas the administrator

3825
02:58:16,730 --> 02:58:15,240
we've had tremendous support engagement

3826
02:58:19,130 --> 02:58:16,740
and focus

3827
02:58:21,530 --> 02:58:19,140
and so um

3828
02:58:22,670 --> 02:58:21,540
and the two it's kind of kind of funny

3829
02:58:25,309 --> 02:58:22,680
uh

3830
02:58:28,730 --> 02:58:25,319
going into the market how committed

3831
02:58:37,250 --> 02:58:28,740
people no idea which badges

3832
02:58:40,730 --> 02:58:38,870
I think this is often something that

3833
02:58:44,210 --> 02:58:40,740
surprises people about large missions

3834
02:58:46,130 --> 02:58:44,220
and it's not just a single take about 14

3835
02:58:58,190 --> 02:58:46,140
minutes

3836
02:59:00,710 --> 02:58:59,330
for those of you joining us for

3837
02:59:02,690 --> 02:59:00,720
listening to live commentary from the

3838
02:59:04,370 --> 02:59:02,700
mock the mission operations center and

3839
02:59:05,630 --> 02:59:04,380
they are latching in place the uh the

3840
02:59:07,670 --> 02:59:05,640
wing of the primary mirror that was

3841
02:59:09,050 --> 02:59:07,680
deployed earlier today that process is

3842
02:59:10,610 --> 02:59:09,060
going to take a few hours and we will be

3843
02:59:11,990 --> 02:59:10,620
here through the whole thing so at the

3844
02:59:13,610 --> 02:59:12,000
end of it we'll be able to say that that

3845
02:59:15,290 --> 02:59:13,620
procedure has been completed

3846
02:59:16,550 --> 02:59:15,300
successfully but Greg we were just

3847
02:59:18,830 --> 02:59:16,560
talking about that a lot of people don't

3848
02:59:20,330 --> 02:59:18,840
realize that that you know pretty much

3849
02:59:21,349 --> 02:59:20,340
you know all of the large missions that

3850
02:59:23,510 --> 02:59:21,359
they may have heard of and everything

3851
02:59:25,010 --> 02:59:23,520
from Mars rovers to the Hubble Space

3852
02:59:26,929 --> 02:59:25,020
Telescope and now the web telescope

3853
02:59:28,730 --> 02:59:26,939
these are international collaborations

3854
02:59:30,950 --> 02:59:28,740
and not just that collaborations between

3855
02:59:33,050 --> 02:59:30,960
industrial Partners government Partners

3856
02:59:34,610 --> 02:59:33,060
University Partners all of that maybe

3857
02:59:36,290 --> 02:59:34,620
you can give us a sense of just the the

3858
02:59:38,870 --> 02:59:36,300
range of partners that went into

3859
02:59:40,610 --> 02:59:38,880
something like the web mission

3860
02:59:42,530 --> 02:59:40,620
so the partnership but certainly

3861
02:59:44,150 --> 02:59:42,540
internationally includes the European

3862
02:59:48,050 --> 02:59:44,160
space agency and the Canadian space

3863
02:59:49,309 --> 02:59:48,060
agency really uh great Partners uh

3864
02:59:52,070 --> 02:59:49,319
they're partnering with us on many

3865
02:59:54,469 --> 02:59:52,080
missions and and they've brought a lot

3866
02:59:56,269 --> 02:59:54,479
to have instruments and there you have

3867
02:59:58,990 --> 02:59:56,279
five launch vehicle and we really

3868
03:00:02,570 --> 02:59:59,000
appreciate uh of course in the U.S

3869
03:00:05,030 --> 03:00:02,580
states 14 countries across the globe

3870
03:00:08,450 --> 03:00:05,040
saw a tremendous amount of support and

3871
03:00:10,490 --> 03:00:08,460
engagement that excellent development to

3872
03:00:13,370 --> 03:00:10,500
get web to this point and further along

3873
03:00:15,110 --> 03:00:13,380
in the operations so it's been a huge

3874
03:00:17,630 --> 03:00:15,120
team

3875
03:00:19,070 --> 03:00:17,640
um and and the industrial basis is

3876
03:00:21,050 --> 03:00:19,080
almost Limitless

3877
03:00:23,030 --> 03:00:21,060
if I try to name all of the the

3878
03:00:24,830 --> 03:00:23,040
companies and institutes and

3879
03:00:26,690 --> 03:00:24,840
universities I'd probably be here until

3880
03:00:28,429 --> 03:00:26,700
late today

3881
03:00:30,410 --> 03:00:28,439
um and and over the life of the

3882
03:00:33,290 --> 03:00:30,420
development more than 10 000 people have

3883
03:00:34,910 --> 03:00:33,300
actually touched web and externally we

3884
03:00:37,790 --> 03:00:34,920
we talk a lot when we go to schools and

3885
03:00:40,309 --> 03:00:37,800
things about technical careers many

3886
03:00:43,730 --> 03:00:40,319
people have touched Webb uh made it

3887
03:00:44,990 --> 03:00:43,740
possible including book Affairs and

3888
03:00:47,750 --> 03:00:45,000
finance

3889
03:00:50,269 --> 03:00:47,760
all types of disciplines of course they

3890
03:00:52,550 --> 03:00:50,279
have a lift thinking was done technical

3891
03:00:55,730 --> 03:00:52,560
teams

3892
03:00:59,750 --> 03:00:57,830
your careers so what what you know what

3893
03:01:02,030 --> 03:00:59,760
was your education and how did how did

3894
03:01:05,330 --> 03:01:02,040
your career bring you to this point

3895
03:01:07,910 --> 03:01:05,340
see so I'm I'm a double e

3896
03:01:10,130 --> 03:01:07,920
um and I started my career in industry

3897
03:01:13,370 --> 03:01:10,140
and then many years ago seemed so long

3898
03:01:15,590 --> 03:01:13,380
ago uh I got a space flight center I've

3899
03:01:19,610 --> 03:01:15,600
had many leadership roles

3900
03:01:21,170 --> 03:01:19,620
at Goddard uh at headquarters I was

3901
03:01:23,389 --> 03:01:21,180
Deputy out of the Glenn Research Center

3902
03:01:25,190 --> 03:01:23,399
for a couple years and prior to this

3903
03:01:29,630 --> 03:01:25,200
role I was uh

3904
03:01:32,150 --> 03:01:29,640
paid an SMD for programs which consists

3905
03:01:34,070 --> 03:01:32,160
of oversight of all of the

3906
03:01:36,469 --> 03:01:34,080
smms I think at the time they were

3907
03:01:38,870 --> 03:01:36,479
between 110 and 114

3908
03:01:41,389 --> 03:01:38,880
and then um

3909
03:01:43,969 --> 03:01:41,399
four years ago someone Twisted both of

3910
03:01:46,070 --> 03:01:43,979
my arms and said let's go look at this

3911
03:01:48,710 --> 03:01:46,080
thing over the goal line and and I think

3912
03:01:51,590 --> 03:01:48,720
we're pretty close

3913
03:01:53,389 --> 03:01:51,600
and just of course you know that NASA

3914
03:01:55,550 --> 03:01:53,399
loves acronyms SMD stands for the

3915
03:01:56,510 --> 03:01:55,560
science Mission directorate and as Greg

3916
03:01:58,730 --> 03:01:56,520
was saying the science Mission

3917
03:02:00,290 --> 03:01:58,740
directorate now has it's it's over a

3918
03:02:01,910 --> 03:02:00,300
hundred of course it changes week to

3919
03:02:03,469 --> 03:02:01,920
week as different missions launch and

3920
03:02:05,630 --> 03:02:03,479
different missions uh come to the end of

3921
03:02:08,150 --> 03:02:05,640
their lifetime but uh over over a

3922
03:02:10,790 --> 03:02:08,160
hundred uh missions all being science

3923
03:02:12,590 --> 03:02:10,800
Mission directorate at Nasa and again uh

3924
03:02:15,349 --> 03:02:12,600
perhaps uh perhaps those of you who

3925
03:02:18,370 --> 03:02:15,359
don't know what a double e is Greg what

3926
03:02:22,309 --> 03:02:20,570
electrical engineer

3927
03:02:25,130 --> 03:02:22,319
absolutely

3928
03:02:26,690 --> 03:02:25,140
so this you know the the wonderful

3929
03:02:28,130 --> 03:02:26,700
groundwork that you've laid with these

3930
03:02:30,469 --> 03:02:28,140
Partnerships you know and working

3931
03:02:31,910 --> 03:02:30,479
together you know I mean how does how

3932
03:02:34,370 --> 03:02:31,920
would this Mission shape the future of

3933
03:02:36,710 --> 03:02:34,380
astrophysics at NASA

3934
03:02:39,290 --> 03:02:36,720
so you've probably heard from some of us

3935
03:02:41,630 --> 03:02:39,300
you hear from boy uh so from uh what I

3936
03:02:46,070 --> 03:02:41,640
would call a Layman standpoint uh

3937
03:02:49,010 --> 03:02:46,080
certainly for NASA it's huge it adds to

3938
03:02:51,410 --> 03:02:49,020
the history of what NASA can do uh very

3939
03:02:54,050 --> 03:02:51,420
complex large missions

3940
03:02:56,269 --> 03:02:54,060
really open the doors for for many

3941
03:02:57,670 --> 03:02:56,279
discoveries and of course you've heard

3942
03:02:59,809 --> 03:02:57,680
all of the

3943
03:03:03,230 --> 03:02:59,819
Discovery certainly searching for with

3944
03:03:04,849 --> 03:03:03,240
web including looking back 13 and a half

3945
03:03:07,610 --> 03:03:04,859
plus billion years

3946
03:03:09,710 --> 03:03:07,620
between there and uh looking at having a

3947
03:03:13,309 --> 03:03:09,720
little habitability of

3948
03:03:15,950 --> 03:03:13,319
exoplanets and also studying within our

3949
03:03:19,190 --> 03:03:15,960
solar system so it's going to do a lot

3950
03:03:21,590 --> 03:03:19,200
a lot better than anything we have today

3951
03:03:23,929 --> 03:03:21,600
so certainly to that but from a

3952
03:03:25,969 --> 03:03:23,939
programmatic standpoint it further shows

3953
03:03:27,950 --> 03:03:25,979
uh with an asset within the broader

3954
03:03:31,010 --> 03:03:27,960
community of stakeholders and across the

3955
03:03:33,290 --> 03:03:31,020
globe uh what what NASA is capable of

3956
03:03:35,090 --> 03:03:33,300
doing and and

3957
03:03:36,769 --> 03:03:35,100
we can actually do a lot more when we

3958
03:03:40,910 --> 03:03:36,779
have excellent Partnerships like we have

3959
03:03:42,530 --> 03:03:40,920
today with our two primary partners

3960
03:03:44,510 --> 03:03:42,540
well Greg thank you so much for joining

3961
03:03:46,910 --> 03:03:44,520
us you know again congratulations on a

3962
03:03:48,590 --> 03:03:46,920
wonderful uh morning but congratulations

3963
03:03:51,170 --> 03:03:48,600
on the excellent leadership that you've

3964
03:03:52,790 --> 03:03:51,180
uh you've led into this program and

3965
03:03:54,769 --> 03:03:52,800
we're going to take a short break now

3966
03:03:56,510 --> 03:03:54,779
we're going to keep these images up in

3967
03:03:57,950 --> 03:03:56,520
front of you uh there there you see Greg

3968
03:03:59,809 --> 03:03:57,960
and me and then we take when we take a

3969
03:04:01,490 --> 03:03:59,819
break you'll see uh continuous images

3970
03:04:03,170 --> 03:04:01,500
from the mock the mission operations

3971
03:04:05,210 --> 03:04:03,180
center at the Space Telescope Science

3972
03:04:06,889 --> 03:04:05,220
Institute and also our Observatory

3973
03:04:09,410 --> 03:04:06,899
visualization tool which you see on the

3974
03:04:11,210 --> 03:04:09,420
left this is a computer generated image

3975
03:04:13,130 --> 03:04:11,220
but it's based on real-time data coming

3976
03:04:14,450 --> 03:04:13,140
down from the observatory so we're going

3977
03:04:16,190 --> 03:04:14,460
to take a short break and we'll be back

3978
03:04:17,929 --> 03:04:16,200
in just a little while to continue our

3979
03:10:38,929 --> 03:04:17,939
live commentary and the commissioning of

3980
03:10:38,939 --> 03:10:45,469
693.085

3981
03:10:45,479 --> 03:11:47,630
we still have three more minutes to go

3982
03:11:47,640 --> 03:11:52,130
and I see that better match complete

3983
03:11:52,140 --> 03:12:12,050
also copy

3984
03:12:16,969 --> 03:12:14,929
our gcp is complete

3985
03:12:19,190 --> 03:12:16,979
and Dropbox copy

3986
03:12:22,190 --> 03:12:19,200
and OC we're ready to continue with

3987
03:12:26,330 --> 03:12:22,200
693.086

3988
03:12:28,190 --> 03:12:26,340
pop one door latch to full 17 of 20.

3989
03:12:29,590 --> 03:12:28,200
the command line looks good you're good

3990
03:12:34,670 --> 03:12:29,600
to execute

3991
03:12:34,680 --> 03:12:38,150
and you're going to continue

3992
03:13:20,630 --> 03:12:39,830
so we go to continue

3993
03:13:30,110 --> 03:13:23,809
and standby for parameter review

3994
03:13:33,469 --> 03:13:32,330
and I see those parameters look good

3995
03:13:34,370 --> 03:13:33,479
you're going to continue with the motor

3996
03:13:36,889 --> 03:13:34,380
move

3997
03:14:19,969 --> 03:13:36,899
but we go to continue with the model

3998
03:14:19,979 --> 03:14:24,290
and the motor move has been progress

3999
03:14:24,300 --> 03:15:55,490
how to copy

4000
03:16:01,610 --> 03:15:58,670
all the Stations of the ROMs with

4001
03:16:08,030 --> 03:16:01,620
47 minutes to get alert and Plantation

4002
03:16:13,729 --> 03:16:10,969
and uh oh see this is gsion Ops be

4003
03:16:17,030 --> 03:16:13,739
advised in 32 minutes will be the end of

4004
03:16:47,450 --> 03:16:17,040
our Command coverage at DSN Canberra

4005
03:17:29,150 --> 03:16:49,670
and I see we're about halfway on this

4006
03:17:29,160 --> 03:19:09,590
cool

4007
03:19:09,600 --> 03:19:16,849
station three four Mississippi

4008
03:19:16,859 --> 03:19:31,269
completely

4009
03:19:38,030 --> 03:19:34,610
hey I see this is

4010
03:19:40,490 --> 03:19:38,040
um the motor moves complete of 17 of 20.

4011
03:19:42,190 --> 03:19:40,500
we're ready to continue

4012
03:19:46,250 --> 03:19:42,200
um with

4013
03:19:48,110 --> 03:19:46,260
693.088 bottom one door lash off so 18

4014
03:19:51,590 --> 03:19:48,120
of 20.

4015
03:19:53,330 --> 03:19:51,600
yeah copy that it's on the window

4016
03:19:56,269 --> 03:19:53,340
and that product looks good you're going

4017
03:19:59,990 --> 03:19:56,279
to execute puppy to see how they go to

4018
03:20:43,670 --> 03:20:02,150
and you're going to continue

4019
03:20:43,680 --> 03:20:47,570
let's stand by for parameter review

4020
03:20:47,580 --> 03:20:59,809
traffic up with standing one

4021
03:21:02,809 --> 03:21:01,790
and the overseas parameters are good

4022
03:21:04,670 --> 03:21:02,819
you're going to continue with the

4023
03:21:06,390 --> 03:21:04,680
measurement I'll be able to continue

4024
03:21:18,110 --> 03:21:06,400
with more remote

4025
03:21:18,120 --> 03:21:32,229
all right

4026
03:21:37,490 --> 03:21:34,490
I don't want to just turn your mic game

4027
03:21:37,500 --> 03:21:41,809
free

4028
03:21:45,590 --> 03:21:44,090
hello and welcome back to live coverage

4029
03:21:47,750 --> 03:21:45,600
of the commissioning of the James Webb

4030
03:21:51,170 --> 03:21:47,760
Space Telescope I'm Michelle Thaller I'm

4031
03:21:53,030 --> 03:21:51,180
joining you here Science Institute

4032
03:21:54,710 --> 03:21:53,040
and you're listening to a live

4033
03:21:56,389 --> 03:21:54,720
commentary

4034
03:21:57,769 --> 03:21:56,399
you'll notice that I'm positing because

4035
03:21:59,450 --> 03:21:57,779
there are different commands coming in

4036
03:22:01,309 --> 03:21:59,460
from the mission operations center or

4037
03:22:04,190 --> 03:22:01,319
the mock uh what has happened this

4038
03:22:06,590 --> 03:22:04,200
morning is we have deployed the final

4039
03:22:08,690 --> 03:22:06,600
part of the primary mirror this giant

4040
03:22:10,729 --> 03:22:08,700
gold coated mirror of the James Webb

4041
03:22:13,010 --> 03:22:10,739
Space Telescope there were two wings

4042
03:22:14,090 --> 03:22:13,020
that had to be deployed into place for

4043
03:22:16,370 --> 03:22:14,100
the whole primary mirror to be

4044
03:22:18,650 --> 03:22:16,380
functioning that has happened and was

4045
03:22:20,750 --> 03:22:18,660
happening now is latching these are

4046
03:22:23,450 --> 03:22:20,760
latches that will secure the mirror into

4047
03:22:25,309 --> 03:22:23,460
its final configuration and you'll hear

4048
03:22:27,170 --> 03:22:25,319
commands going on I'll pause the

4049
03:22:28,729 --> 03:22:27,180
commentary when uh when I hear different

4050
03:22:31,490 --> 03:22:28,739
commands coming in from the mission

4051
03:22:33,769 --> 03:22:31,500
operations center

4052
03:22:35,510 --> 03:22:33,779
so it's been an incredible morning an

4053
03:22:40,490 --> 03:22:35,520
incredible journey for all of us on the

4054
03:22:45,650 --> 03:22:43,670
and uh is now on its way out to its

4055
03:22:48,050 --> 03:22:45,660
final uh its final location its final

4056
03:22:53,809 --> 03:22:48,060
parking orbit at L2 a LaGrange point

4057
03:22:58,429 --> 03:22:56,450
of course coverage is a live event and

4058
03:23:01,790 --> 03:22:58,439
this schedule is set by the engineering

4059
03:23:04,309 --> 03:23:01,800
so we don't know exactly what time this

4060
03:23:06,590 --> 03:23:04,319
will end the idea is that we will be

4061
03:23:08,630 --> 03:23:06,600
here through the lectures

4062
03:23:11,469 --> 03:23:08,640
that looks like that proc's complete and

4063
03:23:14,870 --> 03:23:11,479
we are ready to continue with

4064
03:23:17,750 --> 03:23:14,880
693.089 bottom one door latch to Safe

4065
03:23:19,610 --> 03:23:17,760
move 19 of 20. manned line looks good

4066
03:23:25,250 --> 03:23:19,620
you're going to execute

4067
03:23:30,650 --> 03:23:26,870
and you're going to continue

4068
03:23:34,610 --> 03:23:32,690
so by the end of the broadcast we will

4069
03:23:36,830 --> 03:23:34,620
have uh the final confirmation that

4070
03:23:39,349 --> 03:23:36,840
everything is latched into place and

4071
03:23:41,990 --> 03:23:39,359
this has been an amazing couple days of

4072
03:23:43,250 --> 03:23:42,000
the the major installations required for

4073
03:23:45,950 --> 03:23:43,260
the functioning of the James Webb Space

4074
03:23:49,370 --> 03:23:45,960
Telescope it's not the end we still have

4075
03:23:50,510 --> 03:23:49,380
plenty left to do so uh um we will the

4076
03:23:52,490 --> 03:23:50,520
next thing after this is that the

4077
03:23:54,290 --> 03:23:52,500
telescope will have to cool down and

4078
03:23:56,630 --> 03:23:54,300
then we will begin commissioning the

4079
03:23:58,729 --> 03:23:56,640
primary mirror which is in 18 separate

4080
03:24:00,710 --> 03:23:58,739
segments each of those segments can be

4081
03:24:03,710 --> 03:24:00,720
individually moved to focus this into

4082
03:24:05,809 --> 03:24:03,720
one large functioning telescope

4083
03:24:09,170 --> 03:24:05,819
and I believe with me I'm going to have

4084
03:24:15,650 --> 03:24:09,180
Julie van kampen Julie is the Deputy uh

4085
03:24:18,830 --> 03:24:17,330
and so what you'll see on your screen is

4086
03:24:20,929 --> 03:24:18,840
you'll see a Julie and I on the bottom

4087
03:24:23,030 --> 03:24:20,939
here above us his live coverage from the

4088
03:24:25,190 --> 03:24:23,040
mock and oh at the moment it's just us

4089
03:24:27,290 --> 03:24:25,200
and then there'll also be data coming in

4090
03:24:28,849 --> 03:24:27,300
on an observatory visualization tool to

4091
03:24:31,070 --> 03:24:28,859
show us what the observatory is doing at

4092
03:24:32,870 --> 03:24:31,080
the moment so um Julie we have a few

4093
03:24:33,889 --> 03:24:32,880
moments and I know that one of the

4094
03:24:36,769 --> 03:24:33,899
things we're getting lots of questions

4095
03:24:38,150 --> 03:24:36,779
about are careers in science and we have

4096
03:24:40,190 --> 03:24:38,160
two sort of different people to

4097
03:24:43,490 --> 03:24:40,200
represent engineering and the science

4098
03:24:45,410 --> 03:24:43,500
aspect of working for NASA so um how

4099
03:24:46,790 --> 03:24:45,420
about uh how about if you start out tell

4100
03:24:48,469 --> 03:24:46,800
us a bit about careers in science and

4101
03:24:50,290 --> 03:24:48,479
how you came to be in the position that

4102
03:24:54,229 --> 03:24:50,300
you're in now Julie

4103
03:24:55,969 --> 03:24:54,239
oh well going through

4104
03:24:57,650 --> 03:24:55,979
um you know everybody that you've talked

4105
03:24:59,330 --> 03:24:57,660
to today has talked to you've asked the

4106
03:25:01,490 --> 03:24:59,340
same question and gone through the how

4107
03:25:03,349 --> 03:25:01,500
they've become uh careers in science and

4108
03:25:05,809 --> 03:25:03,359
and I think it's it's really interesting

4109
03:25:07,550 --> 03:25:05,819
to hear how everybody kind of like

4110
03:25:08,929 --> 03:25:07,560
everybody kind of goes back to like how

4111
03:25:10,250 --> 03:25:08,939
they got started and then they talk

4112
03:25:10,849 --> 03:25:10,260
about

4113
03:25:12,469 --> 03:25:10,859
um

4114
03:25:14,990 --> 03:25:12,479
you know kind of where they went through

4115
03:25:17,630 --> 03:25:15,000
their career but I think uh a couple

4116
03:25:19,070 --> 03:25:17,640
people have said uh a couple of really

4117
03:25:20,690 --> 03:25:19,080
important things and you even mentioned

4118
03:25:23,990 --> 03:25:20,700
it once when you were talking about the

4119
03:25:27,469 --> 03:25:24,000
the pilots that flew the plane to bring

4120
03:25:29,630 --> 03:25:27,479
the uh the telescope to a particular

4121
03:25:32,090 --> 03:25:29,640
place or portions of the telescope to a

4122
03:25:34,490 --> 03:25:32,100
particular place what's

4123
03:25:35,750 --> 03:25:34,500
always been

4124
03:25:37,849 --> 03:25:35,760
um

4125
03:25:39,710 --> 03:25:37,859
something that I knew that I wanted to

4126
03:25:41,570 --> 03:25:39,720
do and I didn't necessarily know I

4127
03:25:43,010 --> 03:25:41,580
wanted to be an engineer and I didn't

4128
03:25:45,290 --> 03:25:43,020
necessarily know that I wanted to work

4129
03:25:47,330 --> 03:25:45,300
for NASA but what I did know is that I

4130
03:25:49,969 --> 03:25:47,340
wanted to do something that I really

4131
03:25:51,349 --> 03:25:49,979
cared about and I think

4132
03:25:52,969 --> 03:25:51,359
um you know as you've gone through your

4133
03:25:55,610 --> 03:25:52,979
program today you've you've seen

4134
03:25:57,830 --> 03:25:55,620
technicians working in the clean room

4135
03:26:00,050 --> 03:25:57,840
um you've seen machinists you've seen

4136
03:26:01,729 --> 03:26:00,060
people who had to work in coding

4137
03:26:03,290 --> 03:26:01,739
departments

4138
03:26:06,229 --> 03:26:03,300
um you've talked to lots of engineers in

4139
03:26:09,290 --> 03:26:06,239
science uh scientists

4140
03:26:12,469 --> 03:26:09,300
and the thing that that everyone

4141
03:26:14,150 --> 03:26:12,479
um has in common and Greg had mentioned

4142
03:26:16,490 --> 03:26:14,160
how many people over the years had

4143
03:26:18,769 --> 03:26:16,500
really kind of touched jwst throughout

4144
03:26:21,410 --> 03:26:18,779
its life and whether you're a lawyer or

4145
03:26:24,650 --> 03:26:21,420
you're a finance or whether you're in

4146
03:26:25,670 --> 03:26:24,660
the immediate Department here today

4147
03:26:27,650 --> 03:26:25,680
um

4148
03:26:30,830 --> 03:26:27,660
you have to be really excited about what

4149
03:26:33,530 --> 03:26:30,840
you do it almost doesn't matter what it

4150
03:26:35,630 --> 03:26:33,540
is that you do or where you wind up or

4151
03:26:39,349 --> 03:26:35,640
what path that you take to do there as

4152
03:26:41,750 --> 03:26:39,359
long as you find it so compelling that

4153
03:26:42,950 --> 03:26:41,760
you want to get up today and that's what

4154
03:26:44,870 --> 03:26:42,960
you want to do

4155
03:26:47,269 --> 03:26:44,880
and that's and that's

4156
03:26:49,190 --> 03:26:47,279
um you know when people say well what

4157
03:26:51,229 --> 03:26:49,200
should I do what should I study it

4158
03:26:54,110 --> 03:26:51,239
almost really doesn't

4159
03:26:55,910 --> 03:26:54,120
um matter in particular what you pick as

4160
03:26:59,450 --> 03:26:55,920
long as you were really interested in it

4161
03:27:01,309 --> 03:26:59,460
and as long as you find your path to be

4162
03:27:03,229 --> 03:27:01,319
the most exciting thing of your life you

4163
03:27:06,290 --> 03:27:03,239
spend so much of your life doing it you

4164
03:27:09,710 --> 03:27:08,510
I I couldn't agree more Julie I mean

4165
03:27:10,910 --> 03:27:09,720
there's a few things there that you

4166
03:27:13,070 --> 03:27:10,920
touched on that I think are really

4167
03:27:15,050 --> 03:27:13,080
important you know one is the range of

4168
03:27:17,269 --> 03:27:15,060
people that can work for an organization

4169
03:27:19,550 --> 03:27:17,279
like NASA or our partner organizations

4170
03:27:22,010 --> 03:27:19,560
either universities or in the the

4171
03:27:23,450 --> 03:27:22,020
Aerospace industry you know I mean I I

4172
03:27:24,950 --> 03:27:23,460
don't just work with other scientists

4173
03:27:26,450 --> 03:27:24,960
like you mentioned you know when you

4174
03:27:28,429 --> 03:27:26,460
have all of the different nations and

4175
03:27:29,990 --> 03:27:28,439
all the different companies involved you

4176
03:27:32,210 --> 03:27:30,000
know you have lawyers you have people

4177
03:27:33,590 --> 03:27:32,220
that are experts in finances

4178
03:27:35,330 --> 03:27:33,600
um you have all of the people that are

4179
03:27:36,650 --> 03:27:35,340
generating the incredible animations

4180
03:27:38,030 --> 03:27:36,660
that we're seeing you know in the

4181
03:27:40,130 --> 03:27:38,040
computer scientists and the graphics

4182
03:27:41,990 --> 03:27:40,140
people and the visualizers the people

4183
03:27:44,030 --> 03:27:42,000
that can make this uh these beautiful

4184
03:27:46,010 --> 03:27:44,040
images that we see the people that will

4185
03:27:48,530 --> 03:27:46,020
eventually work on the images that come

4186
03:27:51,889 --> 03:27:48,540
down from web there there are so many

4187
03:27:54,229 --> 03:27:51,899
different ways to work at Nasa and you

4188
03:27:56,809 --> 03:27:54,239
know I mean for me it really was a dream

4189
03:27:58,670 --> 03:27:56,819
early on to work at Nasa that's because

4190
03:28:01,790 --> 03:27:58,680
I couldn't get these questions out of my

4191
03:28:04,070 --> 03:28:01,800
head about space I remember we opened

4192
03:28:06,229 --> 03:28:04,080
the program today with uh a little bit

4193
03:28:08,030 --> 03:28:06,239
of a voiceover from Carl Sagan who was a

4194
03:28:10,070 --> 03:28:08,040
a famous scientist when I was growing up

4195
03:28:13,490 --> 03:28:10,080
and when I was 10 years old he had his

4196
03:28:16,490 --> 03:28:13,500
program Cosmos that was back in 1980 and

4197
03:28:18,889 --> 03:28:16,500
I I was so taken with the questions and

4198
03:28:20,630 --> 03:28:18,899
the drama of the universe that even

4199
03:28:22,429 --> 03:28:20,640
though by the time I got to college I

4200
03:28:24,469 --> 03:28:22,439
didn't necessarily find the physics and

4201
03:28:27,290 --> 03:28:24,479
math classes easy I didn't get the best

4202
03:28:29,990 --> 03:28:27,300
grades but I could not stop thinking

4203
03:28:31,729 --> 03:28:30,000
about this and when people sometimes

4204
03:28:33,650 --> 03:28:31,739
your parents will say to me you know how

4205
03:28:36,349 --> 03:28:33,660
can I encourage my child to be a

4206
03:28:38,090 --> 03:28:36,359
scientist and and just like you said

4207
03:28:39,830 --> 03:28:38,100
I'm not so concerned about people

4208
03:28:41,330 --> 03:28:39,840
becoming scientists necessarily or

4209
03:28:44,330 --> 03:28:41,340
Engineers I'm concerned about them

4210
03:28:47,210 --> 03:28:44,340
following their own curiosity and and

4211
03:28:49,849 --> 03:28:47,220
then life becomes a jewelry yeah I mean

4212
03:28:51,710 --> 03:28:49,859
I I am so privileged to work with people

4213
03:28:53,870 --> 03:28:51,720
like you and people that we're seeing

4214
03:28:55,550 --> 03:28:53,880
today in the films and the footage live

4215
03:28:58,490 --> 03:28:55,560
here at the Space Telescope Science

4216
03:28:59,929 --> 03:28:58,500
Institute the the amazing thing is the

4217
03:29:02,090 --> 03:28:59,939
people that we work with and the passion

4218
03:29:06,410 --> 03:29:02,100
that we share

4219
03:29:10,250 --> 03:29:08,809
right so um I believe what we're going

4220
03:29:11,929 --> 03:29:10,260
to do now is talk a bit about the

4221
03:29:13,610 --> 03:29:11,939
science of web so we've just talked

4222
03:29:15,050 --> 03:29:13,620
about all of the passion and all of the

4223
03:29:17,570 --> 03:29:15,060
questions that we answered with the web

4224
03:29:19,130 --> 03:29:17,580
telescope and uh being an astronomer

4225
03:29:21,710 --> 03:29:19,140
like I said this is a particularly

4226
03:29:23,809 --> 03:29:21,720
exciting time for me I am personally

4227
03:29:25,250 --> 03:29:23,819
very very much looking forward to the

4228
03:29:28,550 --> 03:29:25,260
data that the web telescope is coming

4229
03:29:29,870 --> 03:29:28,560
back so um I I believe there are a

4230
03:29:31,550 --> 03:29:29,880
couple different animations we can run

4231
03:29:33,710 --> 03:29:31,560
while we talk about the science first of

4232
03:29:36,830 --> 03:29:33,720
all let me talk about why the web

4233
03:29:38,330 --> 03:29:36,840
telescope is an infrared telescope and

4234
03:29:40,010 --> 03:29:38,340
this is something that's different from

4235
03:29:42,110 --> 03:29:40,020
our eyes our eyes are not sensitive to

4236
03:29:44,210 --> 03:29:42,120
this color so infrared is a type of

4237
03:29:46,370 --> 03:29:44,220
light that is a lower energy light than

4238
03:29:47,870 --> 03:29:46,380
the eye the light that our eye sees what

4239
03:29:50,210 --> 03:29:47,880
you see here is the electromagnetic

4240
03:29:52,969 --> 03:29:50,220
spectrum but that's a word a term for

4241
03:29:55,309 --> 03:29:52,979
all of the type of light that exists and

4242
03:29:57,229 --> 03:29:55,319
our eyes are only sensitive to a tiny

4243
03:29:58,790 --> 03:29:57,239
bit of that so you know the

4244
03:30:00,410 --> 03:29:58,800
electromagnetic spectrum includes things

4245
03:30:02,570 --> 03:30:00,420
like gamma rays and x-rays and

4246
03:30:04,429 --> 03:30:02,580
UltraViolet that's over to the left of

4247
03:30:06,769 --> 03:30:04,439
your screen and those are types of

4248
03:30:09,170 --> 03:30:06,779
lights that are just too high energy for

4249
03:30:10,010 --> 03:30:09,180
our eyes to detect and then as you go on

4250
03:30:11,450 --> 03:30:10,020
to the other parts of the

4251
03:30:13,490 --> 03:30:11,460
electromagnetic spectrum you have things

4252
03:30:15,349 --> 03:30:13,500
like infrared light which we commonly

4253
03:30:18,530 --> 03:30:15,359
think of as heat light or also

4254
03:30:20,750 --> 03:30:18,540
microwaves and radio these are all parts

4255
03:30:22,429 --> 03:30:20,760
of light just things that we are not

4256
03:30:24,050 --> 03:30:22,439
sensitive to and there have been

4257
03:30:25,610 --> 03:30:24,060
telescopes before that have looked a

4258
03:30:27,170 --> 03:30:25,620
little bit in space into these different

4259
03:30:29,269 --> 03:30:27,180
types of light the Hubble Space

4260
03:30:30,349 --> 03:30:29,279
Telescope saw a little bit and still

4261
03:30:33,349 --> 03:30:30,359
does see a little bit into the

4262
03:30:35,570 --> 03:30:33,359
ultraviolet and the infrared and the

4263
03:30:38,030 --> 03:30:35,580
Spitzer Space Telescope was a mission

4264
03:30:40,550 --> 03:30:38,040
that that launched uh that I was part of

4265
03:30:42,469 --> 03:30:40,560
all the way back in 1998 I started

4266
03:30:44,570 --> 03:30:42,479
working on the specific Space Telescope

4267
03:30:46,729 --> 03:30:44,580
Mission and you can see that James Webb

4268
03:30:49,550 --> 03:30:46,739
was designed to look at this particular

4269
03:30:51,769 --> 03:30:49,560
wavelength of light infrared light and

4270
03:30:54,530 --> 03:30:51,779
infrared light has several incredible

4271
03:30:56,090 --> 03:30:54,540
advantages to it this is a famous image

4272
03:30:57,830 --> 03:30:56,100
from the Hubble Space Telescope in

4273
03:30:59,690 --> 03:30:57,840
visible light the type of light that our

4274
03:31:02,389 --> 03:30:59,700
eye sees of something called The Pillars

4275
03:31:05,030 --> 03:31:02,399
of Creation these are giant clouds of

4276
03:31:07,729 --> 03:31:05,040
dust and gas they are there are hundreds

4277
03:31:09,349 --> 03:31:07,739
of billions of miles across and this

4278
03:31:12,110 --> 03:31:09,359
image that you see here in infrared

4279
03:31:13,670 --> 03:31:12,120
that's a real image so this is an image

4280
03:31:15,229 --> 03:31:13,680
taken by the Hubble Space Telescope

4281
03:31:17,870 --> 03:31:15,239
looking a little bit into the infrared

4282
03:31:20,510 --> 03:31:17,880
our eyes can't see this it's invisible

4283
03:31:22,849 --> 03:31:20,520
to our eyes but all of those stars that

4284
03:31:25,729 --> 03:31:22,859
you're seeing there are really there the

4285
03:31:27,710 --> 03:31:25,739
light was obscured by dust visible light

4286
03:31:29,809 --> 03:31:27,720
that our eye sees is very easily

4287
03:31:31,250 --> 03:31:29,819
obscured by dust and some of the more

4288
03:31:33,830 --> 03:31:31,260
interesting things in the universe

4289
03:31:36,290 --> 03:31:33,840
actually happen inside these big clouds

4290
03:31:38,330 --> 03:31:36,300
and dust and gas this is a visualization

4291
03:31:40,969 --> 03:31:38,340
again produced by our amazing animators

4292
03:31:43,849 --> 03:31:40,979
based on real Hubble observations of the

4293
03:31:46,550 --> 03:31:43,859
Orion Nebula the Orion Nebula is one of

4294
03:31:48,769 --> 03:31:46,560
the largest places close to us in our

4295
03:31:51,889 --> 03:31:48,779
galaxy where new stars and planetary

4296
03:31:54,229 --> 03:31:51,899
systems are forming by the thousands and

4297
03:31:57,229 --> 03:31:54,239
inside this Cloud we see all of these

4298
03:31:59,090 --> 03:31:57,239
young Stars young planetary systems uh

4299
03:32:01,250 --> 03:31:59,100
normally much of this cloud is obscured

4300
03:32:03,650 --> 03:32:01,260
from us the dust is so thick we can't

4301
03:32:04,969 --> 03:32:03,660
see it uh but in infrared we can see

4302
03:32:07,250 --> 03:32:04,979
right through that dust and we can

4303
03:32:09,110 --> 03:32:07,260
actually you'll really have a chance to

4304
03:32:11,929 --> 03:32:09,120
witness the birth of stars and planets

4305
03:32:14,090 --> 03:32:11,939
themselves so infrared has this very

4306
03:32:16,210 --> 03:32:14,100
specific property of being able to see

4307
03:32:19,130 --> 03:32:16,220
places we can't see with visible light

4308
03:32:20,929 --> 03:32:19,140
and this is also something that comes in

4309
03:32:23,809 --> 03:32:20,939
handy with seeing the very early

4310
03:32:26,210 --> 03:32:23,819
universe the farther away you look out

4311
03:32:28,550 --> 03:32:26,220
into space the longer that light has

4312
03:32:30,889 --> 03:32:28,560
taken time to travel to us light travels

4313
03:32:33,769 --> 03:32:30,899
at 186 000 miles per second that's very

4314
03:32:36,290 --> 03:32:33,779
fast but it is a finite speed the Hubble

4315
03:32:38,330 --> 03:32:36,300
Space Telescope could see uh so far away

4316
03:32:41,030 --> 03:32:38,340
that the light was coming to us about

4317
03:32:43,010 --> 03:32:41,040
500 million years after the big bang but

4318
03:32:45,530 --> 03:32:43,020
Webb can see farther still

4319
03:32:47,690 --> 03:32:45,540
Webb can actually look so far away that

4320
03:32:49,969 --> 03:32:47,700
it's looking back to a time where the

4321
03:32:51,950 --> 03:32:49,979
light left when the universe was only a

4322
03:32:54,290 --> 03:32:51,960
couple hundred million years old that's

4323
03:32:56,929 --> 03:32:54,300
amazing that's actually the time when

4324
03:32:59,210 --> 03:32:56,939
the very first galaxies were forming and

4325
03:33:01,309 --> 03:32:59,220
this is a visualization based on on

4326
03:33:03,349 --> 03:33:01,319
physics based on how we think the early

4327
03:33:05,990 --> 03:33:03,359
Universe came together what you're

4328
03:33:08,150 --> 03:33:06,000
seeing here are young galaxies a galaxy

4329
03:33:10,610 --> 03:33:08,160
is a family of hundreds of billions of

4330
03:33:12,769 --> 03:33:10,620
stars and in the early Universe there

4331
03:33:15,050 --> 03:33:12,779
were many smaller galaxies that began to

4332
03:33:17,450 --> 03:33:15,060
combine into the large galaxies we see

4333
03:33:19,969 --> 03:33:17,460
today like our own Milky Way galaxy our

4334
03:33:22,010 --> 03:33:19,979
own Milky Way galaxy today has half a

4335
03:33:23,929 --> 03:33:22,020
trillion Stars more than 500 billion

4336
03:33:26,510 --> 03:33:23,939
stars it's a hundred thousand light

4337
03:33:29,090 --> 03:33:26,520
years across from end to end but we're

4338
03:33:31,550 --> 03:33:29,100
also part of a cluster of galaxies and

4339
03:33:33,349 --> 03:33:31,560
galaxies seem to Cluster together based

4340
03:33:35,510 --> 03:33:33,359
on something called dark matter that was

4341
03:33:37,190 --> 03:33:35,520
present in the early Universe web is

4342
03:33:39,349 --> 03:33:37,200
going to be probing this mysterious form

4343
03:33:41,929 --> 03:33:39,359
of matter and trying to understand how

4344
03:33:43,910 --> 03:33:41,939
it led to the formation of galaxies and

4345
03:33:45,590 --> 03:33:43,920
of course the Stars the planets and

4346
03:33:47,210 --> 03:33:45,600
everything else that we see today

4347
03:33:49,070 --> 03:33:47,220
what you're looking at right now are

4348
03:33:51,290 --> 03:33:49,080
some beautiful pictures of galaxies from

4349
03:33:52,670 --> 03:33:51,300
the Hubble telescope another thing that

4350
03:33:54,170 --> 03:33:52,680
we're really proud about with the web

4351
03:33:56,389 --> 03:33:54,180
telescope and really looking forward to

4352
03:33:59,030 --> 03:33:56,399
is we think we will have the ability to

4353
03:34:02,570 --> 03:33:59,040
understand what exoplanets are like

4354
03:34:04,010 --> 03:34:02,580
so exoplanets are our wonderful objects

4355
03:34:07,370 --> 03:34:04,020
that are planets going around other

4356
03:34:09,110 --> 03:34:07,380
stars so far we can measure the mass of

4357
03:34:10,969 --> 03:34:09,120
these planets so we can measure their

4358
03:34:12,950 --> 03:34:10,979
density but we really have no

4359
03:34:15,050 --> 03:34:12,960
understanding of their environments do

4360
03:34:16,670 --> 03:34:15,060
they have atmospheres like the Earth are

4361
03:34:19,610 --> 03:34:16,680
there things like water vapor present

4362
03:34:21,710 --> 03:34:19,620
carbon monoxide carbon dioxide the way

4363
03:34:24,530 --> 03:34:21,720
we find that is we watch the planet

4364
03:34:26,210 --> 03:34:24,540
actually we call transit in front of its

4365
03:34:28,370 --> 03:34:26,220
star actually make a tiny little solar

4366
03:34:30,650 --> 03:34:28,380
eclipse and when that happens The

4367
03:34:32,870 --> 03:34:30,660
Starlight shines through the atmosphere

4368
03:34:34,490 --> 03:34:32,880
of that planet and some of it goes right

4369
03:34:36,710 --> 03:34:34,500
on through the atmosphere and continues

4370
03:34:38,990 --> 03:34:36,720
toward us and the web telescope can pick

4371
03:34:41,510 --> 03:34:39,000
up that radiation and actually analyze

4372
03:34:43,309 --> 03:34:41,520
what's inside that that atmosphere the

4373
03:34:45,170 --> 03:34:43,319
reason we're able to do that is that

4374
03:34:47,570 --> 03:34:45,180
every different chemical like for

4375
03:34:49,969 --> 03:34:47,580
example oxygen carbon dioxide water

4376
03:34:52,010 --> 03:34:49,979
vapor methane all of these have very

4377
03:34:54,590 --> 03:34:52,020
specific wavelengths of light that are

4378
03:34:56,570 --> 03:34:54,600
absorbed and because of that with the

4379
03:34:59,510 --> 03:34:56,580
light we can tell what that atmosphere

4380
03:35:01,130 --> 03:34:59,520
is actually made of made of so so it's

4381
03:35:02,809 --> 03:35:01,140
it's a wonderful chance to give you a

4382
03:35:05,030 --> 03:35:02,819
little bit of a recap of some of the

4383
03:35:08,150 --> 03:35:05,040
major science goals of the web telescope

4384
03:35:09,290 --> 03:35:08,160
and uh I guess at the moment we are

4385
03:35:11,690 --> 03:35:09,300
getting ready for some of the more

4386
03:35:13,550 --> 03:35:11,700
significant calls we're going to take a

4387
03:35:14,809 --> 03:35:13,560
small break right now as we get ready

4388
03:35:17,870 --> 03:35:14,819
for some of the final latching

4389
03:35:19,790 --> 03:35:17,880
procedures uh so here again I'm joined

4390
03:35:22,010 --> 03:35:19,800
by by Julie van kampen we will be back

4391
03:35:23,929 --> 03:35:22,020
later we are going to be uh taking a

4392
03:35:26,570 --> 03:35:23,939
short break as we get ready for some of

4393
03:35:29,269 --> 03:35:26,580
the the finale of the latching

4394
03:35:31,250 --> 03:35:29,279
procedures coming up

4395
03:35:32,570 --> 03:35:31,260
you're watching live coverage of the

4396
03:35:39,290 --> 03:35:32,580
commissioning of the James Webb Space

4397
03:35:44,110 --> 03:35:41,410
yeah

4398
03:35:45,769 --> 03:35:44,120
they started at

4399
03:37:38,389 --> 03:35:45,779
54.

4400
03:37:38,399 --> 03:37:41,750
faster

4401
03:37:41,760 --> 03:38:27,969
complete

4402
03:38:32,689 --> 03:38:30,830
oh stations be advised we have 10

4403
03:38:34,189 --> 03:38:32,699
minutes of command coverage remaining on

4404
03:38:56,349 --> 03:38:34,199
DSN Canberra

4405
03:39:00,650 --> 03:38:58,269
prayers

4406
03:39:02,229 --> 03:39:00,660
thank you that's not completed we're

4407
03:39:07,269 --> 03:39:02,239
ready for

4408
03:39:16,189 --> 03:39:09,889
the command line looks good you will go

4409
03:39:40,490 --> 03:39:17,929
and you're going to continue

4410
03:39:44,330 --> 03:39:42,110
e at the Space Telescope Science

4411
03:39:47,809 --> 03:39:44,340
Institute in Baltimore Maryland and I'm

4412
03:39:49,429 --> 03:39:47,819
joined by uh Julian campus she is the uh

4413
03:39:51,950 --> 03:39:49,439
the deputy commissioning engineer for

4414
03:39:53,570 --> 03:39:51,960
the James Webb Space Telescope we had a

4415
03:39:55,670 --> 03:39:53,580
wonderfully active and successful

4416
03:39:57,889 --> 03:39:55,680
morning where the second wing of the

4417
03:40:00,229 --> 03:39:57,899
primary mirror was deployed and we are

4418
03:40:03,110 --> 03:40:00,239
now in these weasels of latching that

4419
03:40:05,870 --> 03:40:04,610
Julie can you give us a little bit of an

4420
03:40:07,010 --> 03:40:05,880
update as to what's going on right now

4421
03:40:08,950 --> 03:40:07,020
and some of the commands that we're

4422
03:40:14,030 --> 03:40:08,960
hearing coming along

4423
03:40:18,830 --> 03:40:15,769
they're getting ready to send the very

4424
03:40:21,710 --> 03:40:18,840
last move command uh to latch the the

4425
03:40:23,929 --> 03:40:21,720
bottom latch of the mirrors that were

4426
03:40:25,550 --> 03:40:23,939
deployed today the uh the wing that was

4427
03:40:26,510 --> 03:40:25,560
deployed today with the three mirrors on

4428
03:40:28,910 --> 03:40:26,520
it

4429
03:40:31,490 --> 03:40:28,920
um this last command uh will take a few

4430
03:40:36,290 --> 03:40:31,500
minutes and it will pull the the latch

4431
03:40:38,689 --> 03:40:36,300
into its final uh full load and uh we

4432
03:40:40,670 --> 03:40:38,699
will hear them talk and and as they give

4433
03:40:43,910 --> 03:40:40,680
that last command and then finally

4434
03:40:47,150 --> 03:40:43,920
they'll verify that the uh the command

4435
03:40:50,809 --> 03:40:47,160
was successful in the voters uh brought

4436
03:40:52,370 --> 03:40:50,819
it to full uh load and you can see

4437
03:40:54,710 --> 03:40:52,380
everybody here in the in the room is

4438
03:40:57,290 --> 03:40:54,720
ready to see that last and final stage

4439
03:40:58,910 --> 03:40:57,300
this is the very last move of our

4440
03:41:02,870 --> 03:40:58,920
deployment sequence

4441
03:41:06,469 --> 03:41:02,880
for the structural deployments for jwst

4442
03:41:07,729 --> 03:41:06,479
just incredible it's been an amazing a

4443
03:41:11,269 --> 03:41:07,739
little bit more than a week now it

4444
03:41:13,729 --> 03:41:11,279
launched on December 25th and uh then

4445
03:41:16,070 --> 03:41:13,739
the uh the amazing Sun field was the

4446
03:41:17,750 --> 03:41:16,080
philosophy began to cool of going down

4447
03:41:20,929 --> 03:41:17,760
to an operating temperature of close to

4448
03:41:23,630 --> 03:41:20,939
minus 400 degrees Fahrenheit

4449
03:41:26,150 --> 03:41:23,640
and uh after that we had the deployment

4450
03:41:28,790 --> 03:41:26,160
of the secondary focusing mirror then

4451
03:41:31,670 --> 03:41:28,800
yesterday saw the deployment of the

4452
03:41:33,349 --> 03:41:31,680
first wing of the primary mirror and uh

4453
03:41:35,389 --> 03:41:33,359
then today that the second one and now

4454
03:41:38,090 --> 03:41:35,399
we are finishing up latching that into

4455
03:41:40,189 --> 03:41:38,100
its final stable configuration those

4456
03:41:41,990 --> 03:41:40,199
latches will not be touched again the

4457
03:41:44,269 --> 03:41:42,000
mirror will be in its file configuration

4458
03:41:45,469 --> 03:41:44,279
but that's not the end uh in the weeks

4459
03:41:47,269 --> 03:41:45,479
to come there are some pretty uh

4460
03:41:49,309 --> 03:41:47,279
important things coming up and maybe

4461
03:41:50,510 --> 03:41:49,319
Julie as we as we're waiting for this

4462
03:41:52,429 --> 03:41:50,520
final conference give us a sense about

4463
03:41:54,469 --> 03:41:52,439
what's coming up next for the uh the

4464
03:41:58,070 --> 03:41:54,479
commissioning of web

4465
03:42:00,650 --> 03:41:58,080
yeah uh over the next several weeks as

4466
03:42:03,769 --> 03:42:00,660
you uh talked with Lou Feinberg earlier

4467
03:42:05,929 --> 03:42:03,779
today we'll be taking the mirrors off of

4468
03:42:07,670 --> 03:42:05,939
their launch position and they're

4469
03:42:09,830 --> 03:42:07,680
they're up against hard stops we'll be

4470
03:42:11,269 --> 03:42:09,840
moving them a half an inch forward uh

4471
03:42:13,969 --> 03:42:11,279
once they're all a half an inch forward

4472
03:42:16,610 --> 03:42:13,979
then we'll start the steps involved in

4473
03:42:19,910 --> 03:42:16,620
actually turning our mirror into a a

4474
03:42:21,950 --> 03:42:19,920
nice clean image a one smooth mirror

4475
03:42:24,830 --> 03:42:21,960
we'll we'll first figure out which

4476
03:42:27,590 --> 03:42:24,840
mirror is which uh for the

4477
03:42:29,389 --> 03:42:27,600
um images that we see off of the sky and

4478
03:42:31,189 --> 03:42:29,399
then we'll bring all those into one

4479
03:42:34,429 --> 03:42:31,199
image and then we'll start to actually

4480
03:42:36,349 --> 03:42:34,439
change the mirror to make sure it's uh

4481
03:42:38,210 --> 03:42:36,359
all in one shape

4482
03:42:40,130 --> 03:42:38,220
um we'll also move the secondary mirror

4483
03:42:42,889 --> 03:42:40,140
which is a couple of days ago we

4484
03:42:44,450 --> 03:42:42,899
deployed the secondary structure

4485
03:42:47,590 --> 03:42:44,460
you can see people starting to get

4486
03:42:51,410 --> 03:42:49,849
yeah they can just kind of see the

4487
03:42:53,450 --> 03:42:51,420
tension there

4488
03:42:57,530 --> 03:42:53,460
um we'll bring the secondary mirror off

4489
03:42:59,510 --> 03:42:57,540
off of its hard stops too and and uh I

4490
03:43:01,729 --> 03:42:59,520
move that forward and back and do a

4491
03:43:04,070 --> 03:43:01,739
final Focus adjust of the telescope

4492
03:43:06,170 --> 03:43:04,080
during that time all of our instruments

4493
03:43:08,870 --> 03:43:06,180
are cooling down and being powered on

4494
03:43:12,170 --> 03:43:08,880
and checked out for the first time we'll

4495
03:43:13,969 --> 03:43:12,180
we'll move our filter wheels and all of

4496
03:43:16,370 --> 03:43:13,979
our mechanisms with inside the

4497
03:43:17,689 --> 03:43:16,380
instruments we'll uh check out our

4498
03:43:19,309 --> 03:43:17,699
detectors and make sure they're

4499
03:43:22,189 --> 03:43:19,319
operating at their their proper

4500
03:43:26,330 --> 03:43:22,199
temperatures and then

4501
03:43:32,929 --> 03:43:30,050
and uh the uh final thing that we'll do

4502
03:43:35,570 --> 03:43:32,939
is we'll start taking images and

4503
03:43:38,330 --> 03:43:35,580
calibrate those instruments uh we'll

4504
03:43:40,130 --> 03:43:38,340
make sure that everything is is set to

4505
03:43:42,050 --> 03:43:40,140
go and ready to start our early science

4506
03:43:46,910 --> 03:43:42,060
operations which you heard several of

4507
03:43:50,929 --> 03:43:48,769
there's a question that we get a lot on

4508
03:43:52,550 --> 03:43:50,939
on social media it might be kind of fun

4509
03:43:54,710 --> 03:43:52,560
to take the time and like I said we will

4510
03:43:55,910 --> 03:43:54,720
break our commentary when we see that

4511
03:43:58,429 --> 03:43:55,920
the command has come through for that

4512
03:44:00,349 --> 03:43:58,439
final latch but Kelly on Facebook asks

4513
03:44:01,610 --> 03:44:00,359
how do infrared signals taken by the

4514
03:44:03,410 --> 03:44:01,620
James Webb Space Telescope get

4515
03:44:04,910 --> 03:44:03,420
translated into pictures are the

4516
03:44:07,250 --> 03:44:04,920
pictures we will get the same as if we

4517
03:44:10,429 --> 03:44:07,260
looked at it up close at this time we

4518
03:44:12,650 --> 03:44:10,439
have a nominal Los on dss36 our backup

4519
03:44:14,450 --> 03:44:12,660
antenna at Canberra we will continue to

4520
03:44:16,429 --> 03:44:14,460
have Telemetry on the prime antenna for

4521
03:44:20,090 --> 03:44:16,439
another 10 minutes

4522
03:44:21,950 --> 03:44:20,100
demand coverage will end in four minutes

4523
03:44:23,870 --> 03:44:21,960
as the Earth rotates there are different

4524
03:44:25,570 --> 03:44:23,880
uh antennas that the James Webb Space

4525
03:44:28,389 --> 03:44:25,580
Telescope is using to download its

4526
03:44:40,910 --> 03:44:28,399
Telemetry to tell us

4527
03:44:46,070 --> 03:44:43,729
my command button I see that on the

4528
03:44:49,490 --> 03:44:46,080
ground Cecil

4529
03:44:51,830 --> 03:44:49,500
that keyword looks good CC

4530
03:44:57,769 --> 03:44:51,840
next game

4531
03:45:03,889 --> 03:44:59,269
confirmation that the mirror has been

4532
03:45:06,050 --> 03:45:03,899
lasted on Ops uh we've only had 5 000

4533
03:45:08,389 --> 03:45:06,060
steps remaining in our final latch

4534
03:45:15,849 --> 03:45:08,399
reload move

4535
03:45:15,859 --> 03:45:21,769
multiculties three thousand

4536
03:45:21,779 --> 03:45:50,510
foreign

4537
03:45:54,889 --> 03:45:53,090
and we have a fully deployed jwsp

4538
03:45:57,030 --> 03:45:54,899
Observatory

4539
03:45:57,050 --> 03:45:57,040
all right

4540
03:45:59,150 --> 03:45:57,060
[Music]

4541
03:46:03,769 --> 03:45:59,160
[Applause]

4542
03:46:08,150 --> 03:46:05,389
thousands of people around the world

4543
03:46:09,530 --> 03:46:08,160
have worked on this and you see here the

4544
03:46:11,380 --> 03:46:09,540
people at the Space Telescope Science

4545
03:46:16,910 --> 03:46:11,390
Institute in Baltimore Maryland

4546
03:46:18,050 --> 03:46:16,920
[Applause]

4547
03:46:20,510 --> 03:46:18,060
hopefully we'll get a little bit of

4548
03:46:22,070 --> 03:46:20,520
audio from that room too

4549
03:46:23,570 --> 03:46:22,080
even if we don't we can see the Joy on

4550
03:46:25,429 --> 03:46:23,580
their faces

4551
03:46:29,170 --> 03:46:25,439
everybody of course being very careful

4552
03:46:33,469 --> 03:46:32,030
I'm joining you from an isolated room so

4553
03:46:35,809 --> 03:46:33,479
I can talk to you without a mask on

4554
03:46:48,010 --> 03:46:35,819
everybody else is wearing their masks

4555
03:46:52,729 --> 03:46:50,809
even though I'm a floor below the

4556
03:46:55,490 --> 03:46:52,739
control room I can hear people cheering

4557
03:46:58,150 --> 03:46:55,500
in the background

4558
03:47:01,010 --> 03:46:58,160
[Applause]

4559
03:47:04,030 --> 03:47:01,020
stand by for the project manager stand

4560
03:47:04,040 --> 03:47:07,670
I think

4561
03:47:12,830 --> 03:47:09,849
it's okay

4562
03:47:15,670 --> 03:47:12,840
yeah I just want to thank everyone and

4563
03:47:18,229 --> 03:47:15,680
congratulate them on stage mirror move

4564
03:47:20,150 --> 03:47:18,239
the last two weeks have been totally

4565
03:47:22,490 --> 03:47:20,160
amazing

4566
03:47:24,950 --> 03:47:22,500
thousands of people have worked on jvst

4567
03:47:26,630 --> 03:47:24,960
at this point to get get us here

4568
03:47:29,450 --> 03:47:26,640
but I have a couple of special shout

4569
03:47:32,330 --> 03:47:29,460
outs one to the deployment team

4570
03:47:34,250 --> 03:47:32,340
you guys have done a phenomenal job over

4571
03:47:37,670 --> 03:47:34,260
the last two weeks but also over the

4572
03:47:39,309 --> 03:47:37,680
last probably 15 20 years to get it to

4573
03:47:42,950 --> 03:47:39,319
this point

4574
03:47:45,650 --> 03:47:42,960
I do want to also thank the Northrop int

4575
03:47:47,630 --> 03:47:45,660
team and The Goddard folks who

4576
03:47:51,110 --> 03:47:47,640
participated in the actual stowing of

4577
03:47:54,170 --> 03:47:51,120
the observatory about a year ago

4578
03:47:56,389 --> 03:47:54,180
if they hadn't done it perfectly these

4579
03:47:58,490 --> 03:47:56,399
last two weeks would not have gone as

4580
03:48:01,670 --> 03:47:58,500
well as they have

4581
03:48:04,429 --> 03:48:01,680
finally on a personal note

4582

I'll take you to be advised in just a

4587
03:48:29,570 --> 03:48:27,479
few seconds station three four will

4588
03:48:31,070 --> 03:48:29,580
bring down the Uplink we will see a

4589
03:48:43,490 --> 03:48:31,080
brief lot of telemetry at that time

4590
03:48:49,790 --> 03:48:46,969
you can hear me also uh I'm Thomas and

4591
03:48:51,590 --> 03:48:49,800
I'm the head of Science and NASA and I I

4592
03:48:55,550 --> 03:48:51,600
want to tell you

4593
03:48:57,889 --> 03:48:55,560

right now we have

4595
03:49:02,689 --> 03:49:00,600
a deployed telescope on orbit a

4596
03:49:04,790 --> 03:49:02,699
magnificent telescope likes of which the

4597
03:49:07,250 --> 03:49:04,800
world has never seen so how does it feel

4598
03:49:10,230 --> 03:49:07,260

4601
03:49:19,490 --> 03:49:16,920
time

4602
03:49:20,570 --> 03:49:19,500
that most of you would offend with your

4603
03:49:24,410 --> 03:49:20,580
families

4604
03:49:28,429 --> 03:49:24,420

harder than perhaps you ever worked in

4607
03:49:36,050 --> 03:49:33,180
your life and I just want to tell you

4608
03:49:37,330 --> 03:49:36,060

telescopes

4615
03:49:56,650 --> 03:49:55,199
you know what work cannot pay you back

4616
03:49:59,809 --> 03:49:56,660

think of them also in each one of them

4647
03:51:20,150 --> 03:51:18,180
please help Science Institute what a

4648
03:51:22,130 --> 03:51:20,160
great place to be here looking out at

4649
03:51:25,130 --> 03:51:22,140
the trees that we think of the deep

4650
03:51:27,290 --> 03:51:25,140
space and uh you know being a single

4651
03:51:29,090 --> 03:51:27,300
team here and that of course uh the

4652
03:51:31,910 --> 03:51:29,100
partner that's going to add a lot here

4653
03:51:35,030 --> 03:51:31,920
are going forward and

4654
03:51:37,729 --> 03:51:35,040
roll a small Aerospace as we're starting

4655
03:51:38,929 --> 03:51:37,739
to work out with this entire team uh

4656
03:51:41,389 --> 03:51:38,939
going forward

4657
03:51:43,550 --> 03:51:41,399
so what I'd like to do is quickly just

4658
03:51:56,530 --> 03:51:43,560
uh introduce somebody else and frankly I

4659
03:52:02,229 --> 03:52:00,170
I actually have not received more texts

4660
03:52:04,450 --> 03:52:02,239
from anybody else

4661
03:52:08,150 --> 03:52:04,460
except my kids

4662
03:52:12,769 --> 03:52:08,160
uh uh in the last few months and weeks

4663
03:52:17,090 --> 03:52:15,170
work and his partnership and friendship

4664
03:52:19,729 --> 03:52:17,100
as we go forward so I wanted to see what

4665
03:52:21,189 --> 03:52:19,739
he wants to add a couple sentences uh

4666
03:52:26,290 --> 03:52:21,199
you tell me whether it's going to work

4667
03:52:32,929 --> 03:52:29,210
you but he is just talking about how

4668
03:52:34,370 --> 03:52:32,939
much of an honor is to uh to be part of

4669
03:52:36,769 --> 03:52:34,380
this incredible mission

4670
03:52:38,330 --> 03:52:36,779
and uh I think they're uh

4671
03:52:41,330 --> 03:52:38,340
they need to be working on his his audio

4672
03:52:43,729 --> 03:52:41,340
right now it it's something that you

4673
03:52:45,469 --> 03:52:43,739
hear a lot for people at Nasa about how

4674
03:52:47,210 --> 03:52:45,479
privileged we are to work in this group

4675
03:52:48,469 --> 03:52:47,220
it's something that you hear a lot of

4676
03:52:51,410 --> 03:52:48,479
people say that I I have to really

4677
03:52:53,809 --> 03:52:51,420
reiterate just how much we feel this it

4678
03:52:57,050 --> 03:52:53,819
is a tremendous honor and privilege to

4679
03:53:00,170 --> 03:52:57,060
work on something large and to have a

4680
03:53:01,309 --> 03:53:00,180
goal that you know I believe you know is

4681
03:53:04,130 --> 03:53:01,319
Noble

4682
03:53:05,929 --> 03:53:04,140
we are trying to advance knowledge there

4683
03:53:07,910 --> 03:53:05,939
are risks we have never deployed an

4684
03:53:10,250 --> 03:53:07,920
observatory like this before

4685
03:53:12,170 --> 03:53:10,260
tens of thousands of people are actually

4686
03:53:13,670 --> 03:53:12,180
waiting around the world for this to

4687
03:53:16,250 --> 03:53:13,680
work who have worked on this who have

4688
03:53:21,769 --> 03:53:16,260
given years of their life as as Thomas

4689
03:53:30,170 --> 03:53:23,510
so I think with that we're going to uh

4690
03:53:37,370 --> 03:53:33,530
I hear some Applause in the background

4691
03:53:39,769 --> 03:53:37,380
okay so the uh the final guest we have

4692
03:53:43,189 --> 03:53:39,779
is a head of NASA the administrator of

4693
03:53:46,130 --> 03:53:43,199
NASA Bill Nelson uh Bill comes from uh a

4694
03:53:47,510 --> 03:53:46,140
huge amount of experience a former

4695
03:53:50,990 --> 03:53:47,520
Senator and I might also mention a

4696
03:53:53,389 --> 03:53:51,000
former astronaut uh Billy it is an

4697
03:53:59,450 --> 03:53:53,399
honored to have you here please give us

4698
03:54:01,780 --> 03:54:00,830
and unfortunately I think you may have

4699
03:54:03,710 --> 03:54:01,790
to unmute bill

4700
03:54:12,229 --> 03:54:03,720
[Laughter]

4701
03:54:16,189 --> 03:54:14,510
I am unmuted

4702
03:54:19,910 --> 03:54:16,199
there you go

4703
03:54:22,729 --> 03:54:19,920
okay I want to uh

4704
03:54:24,889 --> 03:54:22,739
say again what Thomas just said and what

4705
03:54:29,349 --> 03:54:24,899
Bill Oakes just said

4706
03:54:32,450 --> 03:54:29,359
uh it's an incredible team

4707
03:54:35,210 --> 03:54:32,460
uh NASA

4708
03:54:38,990 --> 03:54:35,220
is a place where

4709
03:54:42,610 --> 03:54:39,000
The Impossible becomes possible

4710
03:54:45,170 --> 03:54:42,620
and that's why so many people have

4711
03:54:49,010 --> 03:54:45,180
stayed with NASA over the years that's

4712
03:54:51,710 --> 03:54:49,020
why nine years in a row NASA has been

4713
03:54:53,809 --> 03:54:51,720
voted as the best place to work in the

4714
03:54:55,429 --> 03:54:53,819
entire federal government nine years in

4715
03:54:58,490 --> 03:54:55,439
a row

4716
03:55:03,710 --> 03:54:58,500
uh we bring in and we value our interns

4717
03:55:07,849 --> 03:55:03,720
from college and we bring them in and

4718
03:55:10,610 --> 03:55:07,859
30 percent of them end up having a a

4719
03:55:12,650 --> 03:55:10,620
career at NASA

4720
03:55:15,490 --> 03:55:12,660
and then we have these incredible

4721
03:55:18,950 --> 03:55:15,500
Partners outside of NASA

4722
03:55:21,290 --> 03:55:18,960
that Thomas has mentioned just just take

4723
03:55:24,170 --> 03:55:21,300
the Aerospace company Northrop Grumman

4724
03:55:26,269 --> 03:55:24,180
that oversaw all this take the people

4725
03:55:30,110 --> 03:55:26,279
that Goddard take the people at the

4726
03:55:34,429 --> 03:55:30,120
Space Telescope Institute

4727
03:55:38,990 --> 03:55:34,439
this is uh just incredible input think

4728
03:55:41,689 --> 03:55:39,000
about the delivery in packaging of that

4729
03:55:43,790 --> 03:55:41,699
telescope when it was put on the ship

4730
03:55:48,010 --> 03:55:43,800
and they had to have special security

4731
03:55:51,410 --> 03:55:48,020
going through the Panama Canal

4732
03:55:54,050 --> 03:55:51,420
and then of course area in space I mean

4733
03:55:57,830 --> 03:55:54,060
right on the money

4734
03:56:00,050 --> 03:55:57,840
and our International Partners which are

4735
03:56:02,630 --> 03:56:00,060
are so important to us

4736
03:56:05,150 --> 03:56:02,640
in this particular mission

4737
03:56:07,610 --> 03:56:05,160
uh the Canadian space agency the

4738
03:56:11,450 --> 03:56:07,620
European Space Agency

4739
03:56:15,729 --> 03:56:11,460
but in NASA at large you know we've got

4740
03:56:18,530 --> 03:56:15,739
over 30 to 50 partners for example

4741
03:56:21,429 --> 03:56:18,540
International involved in the

4742
03:56:24,710 --> 03:56:21,439
International Space Station and look

4743
03:56:27,050 --> 03:56:24,720
look at the politics on Earth where it's

4744
03:56:30,830 --> 03:56:27,060
so rough between Russia

4745
03:56:34,309 --> 03:56:30,840
and the United States right to today

4746
03:56:38,090 --> 03:56:34,319
over terrestrial matters and yet what's

4747
03:56:42,229 --> 03:56:39,950
we're cooperating and we've been

4748
03:56:47,090 --> 03:56:42,239
cooperating in the civilian Space

4749
03:56:52,969 --> 03:56:50,809
when an American spacecraft and a Soviet

4750
03:56:55,729 --> 03:56:52,979
spacecraft Rendezvous and docked and the

4751
03:56:58,490 --> 03:56:55,739
crews lived together for nine days

4752
03:57:01,550 --> 03:56:58,500
and that has continued all the way up to

4753
03:57:04,490 --> 03:57:01,560
today where they the Russians have

4754
03:57:07,010 --> 03:57:04,500
helped us build and operate the

4755
03:57:09,950 --> 03:57:07,020
International Space Station so I give

4756
03:57:12,170 --> 03:57:09,960
you the examples because when people put

4757
03:57:14,570 --> 03:57:12,180
their mind to it

4758
03:57:17,389 --> 03:57:14,580
and start cooperating and working

4759
03:57:20,570 --> 03:57:17,399
together as a team

4760
03:57:23,150 --> 03:57:20,580
as we say at Nasa they

4761
03:57:27,410 --> 03:57:23,160
impossible becomes possible

4762
03:57:31,189 --> 03:57:27,420
and here is another example of that

4763
03:57:34,250 --> 03:57:31,199
so how can I thank you enough

4764
03:57:36,370 --> 03:57:34,260
uh how can I thank the support that

4765
03:57:40,250 --> 03:57:36,380
we've gotten from the White House

4766
03:57:43,250 --> 03:57:40,260
President Biden specifically

4767
03:57:46,370 --> 03:57:43,260
uh is watching this Mission the vice

4768
03:57:49,070 --> 03:57:46,380
president Kamala Harris same thing

4769
03:57:51,290 --> 03:57:49,080
our partners in the house and the Senate

4770
03:57:53,090 --> 03:57:51,300
my old colleagues that I love to

4771
03:57:54,769 --> 03:57:53,100
continue to harass

4772
03:57:57,050 --> 03:57:54,779
uh

4773
03:57:59,150 --> 03:57:57,060
and yet they have supported this I want

4774
03:58:03,170 --> 03:57:59,160
to single out one person

4775
03:58:06,050 --> 03:58:03,180
because James Webb is long overdue and

4776
03:58:07,849 --> 03:58:06,060
it's uh way over budget on the original

4777
03:58:11,510 --> 03:58:07,859
budget

4778
03:58:15,110 --> 03:58:11,520
but James Webb was kept alive in large

4779
03:58:18,650 --> 03:58:15,120
part by Senator Barbara mikulski of

4780
03:58:21,050 --> 03:58:18,660
Maryland now retired I've called her

4781
03:58:24,229 --> 03:58:21,060
personally to thank her

4782
03:58:27,469 --> 03:58:24,239
and indeed this is a proud day for her

4783
03:58:29,510 --> 03:58:27,479
too because when it was needed for

4784
03:58:31,729 --> 03:58:29,520
additional preparations

4785
03:58:34,309 --> 03:58:31,739
she was there

4786
03:58:35,929 --> 03:58:34,319
so what a great day now we got a long

4787
03:58:39,889 --> 03:58:35,939
way to go

4788
03:58:41,450 --> 03:58:39,899
uh we we got to get out there to day 29

4789
03:58:43,510 --> 03:58:41,460
and that the

4790
03:58:45,889 --> 03:58:43,520
those uh

4791
03:58:49,370 --> 03:58:45,899
thrusters have got to work to get us

4792
03:58:52,370 --> 03:58:49,380
into that orbit around L2

4793
03:58:53,929 --> 03:58:52,380
a lot of other mechanisms to work and

4794
03:58:56,990 --> 03:58:53,939
then it's going to take us about six

4795
03:59:01,370 --> 03:58:57,000
months to start receiving those pictures

4796
03:59:05,090 --> 03:59:01,380
but when we do as you have had Michelle

4797
03:59:08,929 --> 03:59:05,100
explain to you oh

4798
03:59:11,990 --> 03:59:08,939
The Horizon is not the limit

4799
03:59:16,250 --> 03:59:12,000
we're going to have all kind of new out

4800
03:59:18,410 --> 03:59:16,260
knowledge about who we are what we are

4801
03:59:21,530 --> 03:59:18,420
where we came from

4802
03:59:22,790 --> 03:59:21,540
are there others out there

4803
03:59:26,630 --> 03:59:22,800
uh

4804
03:59:29,630 --> 03:59:26,640
did any wonder why it's such a privilege

4805
03:59:31,750 --> 03:59:29,640
to be involved in NASA

4806
03:59:36,290 --> 03:59:31,760
so

4807
03:59:37,729 --> 03:59:36,300
just like Thomas I'm emotional too

4808
03:59:45,170 --> 03:59:37,739
thank you

4809
03:59:48,650 --> 03:59:45,180
have you here with us and yes it's a

4810
03:59:50,030 --> 03:59:48,660
very emotional day for all of us

4811
03:59:51,889 --> 03:59:50,040
ah

4812
03:59:54,050 --> 03:59:51,899
absolutely incredible

4813
03:59:56,150 --> 03:59:54,060
so on behalf of everybody here at the

4814
03:59:58,070 --> 03:59:56,160
Space Telescope Science Institute this

4815
03:59:59,870 --> 03:59:58,080
will actually begin the conclusion of

4816
04:00:02,510 --> 03:59:59,880
our broadcast it has been an amazing

4817
04:00:05,030 --> 04:00:02,520
couple of weeks actually first the

4818
04:00:06,950 --> 04:00:05,040
run-up to the launch then the launch uh

4819
04:00:09,590 --> 04:00:06,960
the successful deployment of the

4820
04:00:10,910 --> 04:00:09,600
observatory and we look forward now to a

4821
04:00:12,950 --> 04:00:10,920
few more months

4822
04:00:16,130 --> 04:00:12,960
and until we release those those first

4823
04:00:18,769 --> 04:00:16,140
images and they proved to be amazing

4824
04:00:21,349 --> 04:00:18,779
it's we're all all of it because we're

4825
04:00:23,090 --> 04:00:21,359
all just so happy to be here

4826
04:00:25,969 --> 04:00:23,100
again what we were saying before that

4827
04:00:29,090 --> 04:00:25,979
it's easy you keep hearing it again this

4828
04:00:31,429 --> 04:00:29,100
team of people as much as I love science

4829
04:00:33,590 --> 04:00:31,439
I've been fascinated all my life the

4830
04:00:36,170 --> 04:00:33,600
best part about working at Nasa are the

4831
04:00:38,870 --> 04:00:36,180
people around us none of this is

4832
04:00:40,910 --> 04:00:38,880
possible without everybody listening

4833
04:00:43,189 --> 04:00:40,920
here today people that are members of

4834
04:00:45,050 --> 04:00:43,199
countries all over the world people who

4835
04:00:46,929 --> 04:00:45,060
can support science through their tax

4836
04:00:49,130 --> 04:00:46,939
money people you know at universities

4837
04:00:51,229 --> 04:00:49,140
seriously everywhere in every country

4838
04:00:53,090 --> 04:00:51,239
that there is we are all in this

4839
04:00:55,250 --> 04:00:53,100
together and this is something amazing

4840
04:00:57,050 --> 04:00:55,260
that we have just begun this new journey

4841
04:00:59,150 --> 04:00:57,060
to have an entirely new view of the

4842
04:01:01,189 --> 04:00:59,160
universe it's been an honor to be with

4843
04:01:03,530 --> 04:01:01,199
you through this part of commissioning I

4844
04:01:05,269 --> 04:01:03,540
hope to be here on as this continues uh

4845
04:01:07,010 --> 04:01:05,279
so this is Michelle Thaller wishing you

4846
04:01:23,090 --> 04:01:07,020
a very good day from the Space Telescope
