1
00:00:06,950 --> 00:00:05,030
good evening from nasa's goddard space

2
00:00:09,750 --> 00:00:06,960
flight center located just outside

3
00:00:11,270 --> 00:00:09,760
washington dc and greenbelt maryland you

4
00:00:13,190 --> 00:00:11,280
are currently looking at a live view of

5
00:00:15,749 --> 00:00:13,200
the space telescope operations control

6
00:00:17,910 --> 00:00:15,759
center located here at goddard the space

7
00:00:20,550 --> 00:00:17,920
telescope operations control center also

8
00:00:24,310 --> 00:00:20,560
referred to as the stock is responsible

9
00:00:26,710 --> 00:00:24,320
24 7 365 days a year for monitoring all

10
00:00:29,669 --> 00:00:26,720
hubble systems and facilitating all of

11
00:00:31,429 --> 00:00:29,679
the telescope science observations

12
00:00:32,950 --> 00:00:31,439
as a way of setting the stage for what

13
00:00:35,750 --> 00:00:32,960
will be happening over the coming week

14
00:00:37,830 --> 00:00:35,760
during the sts-125 flight we will now

15
00:00:52,709 --> 00:00:37,840
show a short video feature package about

16
00:00:56,869 --> 00:00:54,950
the stock is the space telescope

17
00:00:58,790 --> 00:00:56,879
operations control center

18
00:01:00,709 --> 00:00:58,800
and in the stock is where we control

19
00:01:04,070 --> 00:01:00,719
hubble we control it on a day-to-day

20
00:01:05,590 --> 00:01:04,080
basis so all the activities we do the

21
00:01:07,270 --> 00:01:05,600
pointing the telescope at the different

22
00:01:09,670 --> 00:01:07,280
targets the different stars different

23
00:01:11,109 --> 00:01:09,680
galaxies getting the data back down

24
00:01:12,630 --> 00:01:11,119
sending commands up to tell a word to

25
00:01:14,710 --> 00:01:12,640
point moving at orington different

26
00:01:17,270 --> 00:01:14,720
positions all that originates in the

27
00:01:18,469 --> 00:01:17,280
stock we have a crew that's there 24

28
00:01:22,630 --> 00:01:18,479
hours a day seven days a week

29
00:01:26,710 --> 00:01:24,870
in normal day to day operations we don't

30
00:01:28,870 --> 00:01:26,720
perform the science activities here

31
00:01:30,069 --> 00:01:28,880
we're really running the telescope the

32
00:01:31,990 --> 00:01:30,079
scientists are up at the science

33
00:01:34,069 --> 00:01:32,000
institute in baltimore so the data is

34
00:01:35,429 --> 00:01:34,079
going to come back down through us and

35
00:01:36,469 --> 00:01:35,439
then get sent up to the scientists in

36
00:01:38,390 --> 00:01:36,479
baltimore and then they're going to

37
00:01:42,149 --> 00:01:38,400
decode the data and understand what

38
00:01:46,550 --> 00:01:44,630
it's a different operational atmosphere

39
00:01:48,710 --> 00:01:46,560
for servicing mission versus novel

40
00:01:51,030 --> 00:01:48,720
operations for a regular day to day we

41
00:01:52,870 --> 00:01:51,040
only have about three or so people

42
00:01:54,630 --> 00:01:52,880
really watching the telescope

43
00:01:56,469 --> 00:01:54,640
and telescopes are built very robustly

44
00:01:58,389 --> 00:01:56,479
if they have a problem they take care of

45
00:02:00,469 --> 00:01:58,399
themselves they put themselves in a safe

46
00:02:01,830 --> 00:02:00,479
state then you go back and you isolate

47
00:02:03,190 --> 00:02:01,840
the problem and fix to see what happens

48
00:02:05,749 --> 00:02:03,200
later on

49
00:02:07,670 --> 00:02:05,759
the difference is during a servicing

50
00:02:09,430 --> 00:02:07,680
mission the astronauts can only be out

51
00:02:10,869 --> 00:02:09,440
for six hours roughly at a time and

52
00:02:13,350 --> 00:02:10,879
that's because of a limit on how much

53
00:02:15,750 --> 00:02:13,360
oxygen water they carry on board so if a

54
00:02:17,430 --> 00:02:15,760
problem occurs we don't have the luxury

55
00:02:19,670 --> 00:02:17,440
of talking about it and debating what

56
00:02:21,830 --> 00:02:19,680
the right course of action is we have to

57
00:02:24,710 --> 00:02:21,840
take action right away so we have a team

58
00:02:26,949 --> 00:02:24,720
of experts who are on console somebody's

59
00:02:29,110 --> 00:02:26,959
watching the power somebody's watching

60
00:02:30,790 --> 00:02:29,120
the communications somebody's watching

61
00:02:32,949 --> 00:02:30,800
how the telescope will point and if they

62
00:02:34,470 --> 00:02:32,959
see a problem in one of those subsystems

63
00:02:36,710 --> 00:02:34,480
they alert the rest of the team and we

64
00:02:38,229 --> 00:02:36,720
have to quickly diagnose that problem

65
00:02:40,150 --> 00:02:38,239
and come up with a resolution because

66
00:02:41,670 --> 00:02:40,160
the astronauts they can't stand around

67
00:02:44,790 --> 00:02:41,680
if they're standing around and

68
00:02:47,270 --> 00:02:44,800
something's not going to get done

69
00:02:48,710 --> 00:02:47,280
so after we get released from the

70
00:02:50,390 --> 00:02:48,720
shuttle we're going to go through a

71
00:02:51,830 --> 00:02:50,400
series of commissioning exercises to

72
00:02:53,110 --> 00:02:51,840
make sure each of these cameras is

73
00:02:54,229 --> 00:02:53,120
working correctly each of these

74
00:02:55,589 --> 00:02:54,239
instruments

75
00:02:57,830 --> 00:02:55,599
so we're going to test them out over a

76
00:02:59,350 --> 00:02:57,840
series of months to make sure that the

77
00:03:01,270 --> 00:02:59,360
picture that we hope to get is really

78
00:03:03,190 --> 00:03:01,280
there and just like learning how to use

79
00:03:04,869 --> 00:03:03,200
any new camera you have to

80
00:03:07,110 --> 00:03:04,879
play with a little bit to try to get the

81
00:03:08,949 --> 00:03:07,120
exact focus exact orientation so it's

82
00:03:10,630 --> 00:03:08,959
working correctly so it really takes

83
00:03:12,949 --> 00:03:10,640
about four to five months after we

84
00:03:15,350 --> 00:03:12,959
release from the shuttle before the

85
00:03:19,190 --> 00:03:15,360
telescope is completely back and working

86
00:03:23,990 --> 00:03:21,430
back now with live mission coverage

87
00:03:25,509 --> 00:03:24,000
during sts-125 there will be two teams

88
00:03:26,470 --> 00:03:25,519
of flight controllers supporting the

89
00:03:28,390 --> 00:03:26,480
stock

90
00:03:30,390 --> 00:03:28,400
currently on duty is the planning team

91
00:03:32,949 --> 00:03:30,400
who have been on console since about 6

92
00:03:34,630 --> 00:03:32,959
pm this evening the other group of stock

93
00:03:36,869 --> 00:03:34,640
flight controllers known as the orbit

94
00:03:39,430 --> 00:03:36,879
team finished their first active mission

95
00:03:40,789 --> 00:03:39,440
shift about three and a half hours ago

96
00:03:42,789 --> 00:03:40,799
earlier this evening we had an

97
00:03:45,030 --> 00:03:42,799
opportunity to talk with the lead of the

98
00:03:47,270 --> 00:03:45,040
orbit team mission operations manager

99
00:03:48,309 --> 00:03:47,280
keith wallias just after he came off

100
00:03:50,309 --> 00:03:48,319
console

101
00:03:52,149 --> 00:03:50,319
we first asked keith about what it was

102
00:03:55,110 --> 00:03:52,159
like in the stock during the launch of

103
00:03:59,030 --> 00:03:57,670
it was great it was a feeling that we've

104
00:04:00,470 --> 00:03:59,040
been here for seven years we've been

105
00:04:02,390 --> 00:04:00,480
great getting ready for the mission to

106
00:04:04,309 --> 00:04:02,400
go and it's finally happened it's just

107
00:04:06,229 --> 00:04:04,319
like again ready for the big game we've

108
00:04:08,949 --> 00:04:06,239
been practicing for years the game is on

109
00:04:12,789 --> 00:04:10,869
we then asked keith to summarize the

110
00:04:18,949 --> 00:04:12,799
activities that took place in the stock

111
00:04:23,110 --> 00:04:21,110
the main big event for today was the

112
00:04:25,510 --> 00:04:23,120
onboard inspection for the crew and that

113
00:04:27,270 --> 00:04:25,520
was taken on most of the day here we

114
00:04:29,110 --> 00:04:27,280
weren't as busy we were just doing some

115
00:04:30,469 --> 00:04:29,120
minor preparations but the real activity

116
00:04:32,230 --> 00:04:30,479
is going to begin in about a half an

117
00:04:34,150 --> 00:04:32,240
hour we're going to close the aperture

118
00:04:36,150 --> 00:04:34,160
door that's the door that hasn't been

119
00:04:37,270 --> 00:04:36,160
closed since 2007. of course we need

120
00:04:39,189 --> 00:04:37,280
that door open if we're going to be

121
00:04:40,469 --> 00:04:39,199
taking pictures but as you get close to

122
00:04:42,710 --> 00:04:40,479
the orbiter you worry about

123
00:04:44,390 --> 00:04:42,720
contamination on our mirror and hst is

124
00:04:46,230 --> 00:04:44,400
so sensitive you can't have any

125
00:04:47,749 --> 00:04:46,240
contamination so in about a half an hour

126
00:04:48,950 --> 00:04:47,759
from now we're going to shut that door

127
00:04:50,469 --> 00:04:48,960
it's going to stay closed for the

128
00:04:51,749 --> 00:04:50,479
duration of the mission and we're not

129
00:04:53,670 --> 00:04:51,759
going to open it until just before they

130
00:04:55,030 --> 00:04:53,680
release us the other big activity that's

131
00:04:56,390 --> 00:04:55,040
going to occur tonight

132
00:04:58,150 --> 00:04:56,400
is we have these large high gain

133
00:04:59,670 --> 00:04:58,160
antennas that we use to communicate with

134
00:05:01,430 --> 00:04:59,680
the telescope all the time center

135
00:05:03,189 --> 00:05:01,440
science data down while our science

136
00:05:04,469 --> 00:05:03,199
instruments are now in a safe state so

137
00:05:06,150 --> 00:05:04,479
we're going to retract those high gain

138
00:05:07,270 --> 00:05:06,160
antennas we're going to pull them in and

139
00:05:08,870 --> 00:05:07,280
they're going to be nested for the

140
00:05:10,870 --> 00:05:08,880
entire mission and we're going to open

141
00:05:12,310 --> 00:05:10,880
them up again shortly before we release

142
00:05:14,550 --> 00:05:12,320
so those are the big activities for

143
00:05:16,070 --> 00:05:14,560
tonight getting the high gain antennas

144
00:05:18,310 --> 00:05:16,080
pulled in and also getting our aperture

145
00:05:20,469 --> 00:05:18,320
door closed

146
00:05:21,830 --> 00:05:20,479
it's a pretty busy day tomorrow we're

147
00:05:24,390 --> 00:05:21,840
going to start off early we're getting

148
00:05:26,629 --> 00:05:24,400
the telescope in a state so that it can

149
00:05:28,150 --> 00:05:26,639
be serviced and just as if you were

150
00:05:29,510 --> 00:05:28,160
doing some work around your house if

151
00:05:31,110 --> 00:05:29,520
you're going to do some electrical work

152
00:05:33,430 --> 00:05:31,120
you want to turn things off that don't

153
00:05:34,710 --> 00:05:33,440
need to be on so we're going to turn off

154
00:05:36,550 --> 00:05:34,720
some of our critical electronic

155
00:05:38,310 --> 00:05:36,560
equipment because you don't want things

156
00:05:40,390 --> 00:05:38,320
to be on and jostled as you're getting

157
00:05:41,749 --> 00:05:40,400
ready to be birthed and grappled so

158
00:05:43,749 --> 00:05:41,759
we're going to start turning some things

159
00:05:45,350 --> 00:05:43,759
off we're going to do some tests make

160
00:05:48,070 --> 00:05:45,360
sure our safe mode test everything is

161
00:05:49,590 --> 00:05:48,080
working correctly we have to turn the

162
00:05:51,590 --> 00:05:49,600
telescope so that the orbiter can

163
00:05:53,110 --> 00:05:51,600
grapple us it's not in a position right

164
00:05:54,469 --> 00:05:53,120
now where it can be grappled so we're

165
00:05:56,390 --> 00:05:54,479
going to send some commands to put it in

166
00:05:58,469 --> 00:05:56,400
the right position so that it can be

167
00:06:00,390 --> 00:05:58,479
grabbed by the orbiter and then finally

168
00:06:01,749 --> 00:06:00,400
just before they grapple with us

169
00:06:03,590 --> 00:06:01,759
we're going to essentially put ourselves

170
00:06:04,870 --> 00:06:03,600
in a drifting state we're not going to

171
00:06:07,029 --> 00:06:04,880
have any control to point anyway

172
00:06:09,029 --> 00:06:07,039
whatsoever so when the orbiter grabs us

173
00:06:10,870 --> 00:06:09,039
it's going to get us and put us into the

174
00:06:12,950 --> 00:06:10,880
back of the bay once we're in the back

175
00:06:15,029 --> 00:06:12,960
of the bay then we start turning things

176
00:06:16,469 --> 00:06:15,039
on again we start applying power to the

177
00:06:18,070 --> 00:06:16,479
vehicle and we're going to start to get

178
00:06:19,830 --> 00:06:18,080
power not only going to charge our

179
00:06:21,590 --> 00:06:19,840
batteries up one more time with the

180
00:06:23,189 --> 00:06:21,600
solar rays but then we're going to go to

181
00:06:24,150 --> 00:06:23,199
internal power from the orbiter and

182
00:06:27,749 --> 00:06:24,160
we're going to get power from the

183
00:06:31,510 --> 00:06:29,830
in an effort to maximize science data

184
00:06:33,350 --> 00:06:31,520
gathering the stock continued with

185
00:06:35,110 --> 00:06:33,360
hubble science operations right up until

186
00:06:36,390 --> 00:06:35,120
the launch of shuttle atlantis yesterday

187
00:06:37,990 --> 00:06:36,400
afternoon

188
00:06:40,070 --> 00:06:38,000
when the call came from mission control

189
00:06:42,230 --> 00:06:40,080
in houston the crew was go for on-orbit

190
00:06:44,629 --> 00:06:42,240
operations the stock team began

191
00:06:46,710 --> 00:06:44,639
transitioning hubble out of science ops

192
00:06:49,350 --> 00:06:46,720
and preparing the observatory for the

193
00:06:51,029 --> 00:06:49,360
shuttle's arrival on wednesday afternoon

194
00:06:52,950 --> 00:06:51,039
as keith mentioned

195
00:06:55,110 --> 00:06:52,960
early tomorrow morning the two large

196
00:06:57,510 --> 00:06:55,120
high gain antenna mast on the telescope

197
00:06:59,589 --> 00:06:57,520
will be retracted that activity should

198
00:07:00,790 --> 00:06:59,599
happen somewhere around 2 am eastern

199
00:07:02,469 --> 00:07:00,800
time

200
00:07:04,390 --> 00:07:02,479
the change in the position of hubble

201
00:07:07,589 --> 00:07:04,400
solar rays that keith talked about

202
00:07:09,430 --> 00:07:07,599
should take place at about 7 45 a.m

203
00:07:11,749 --> 00:07:09,440
and as keith also described the stock

204
00:07:13,510 --> 00:07:11,759
team will be sending commands to reduce

205
00:07:16,230 --> 00:07:13,520
electrical power load demands on the

206
00:07:19,990 --> 00:07:16,240
telescope tomorrow that activity should

207
00:07:21,830 --> 00:07:20,000
happen just before 9 30 a.m eastern time

208
00:07:24,230 --> 00:07:21,840
on wednesday the stock team will also be

209
00:07:26,469 --> 00:07:24,240
turning off some built-in safing systems

210
00:07:28,550 --> 00:07:26,479
on hubble to prevent the observatory

211
00:07:30,390 --> 00:07:28,560
from going into a safe mode condition

212
00:07:31,749 --> 00:07:30,400
just before grapple of the telescope

213
00:07:34,469 --> 00:07:31,759
happens

214
00:07:36,629 --> 00:07:34,479
at about 10 40 am eastern on wednesday

215
00:07:38,550 --> 00:07:36,639
the terminal initiation or ti burn will

216
00:07:40,950 --> 00:07:38,560
take place which will put atlantis on a

217
00:07:42,629 --> 00:07:40,960
final intercept course with hubble

218
00:07:44,629 --> 00:07:42,639
when hubble is within about seven miles

219
00:07:46,710 --> 00:07:44,639
of atlantis commanding by the stock to

220
00:07:48,950 --> 00:07:46,720
the telescope will transition from the

221
00:07:50,790 --> 00:07:48,960
tdrs system to the space shuttle's

222
00:07:52,309 --> 00:07:50,800
s-band communications

223
00:07:53,830 --> 00:07:52,319
use of s-band communication will

224
00:07:55,189 --> 00:07:53,840
continue until after hubble is

225
00:07:56,710 --> 00:07:55,199
redeployed

226
00:07:58,390 --> 00:07:56,720
and the shuttle is greater than seven

227
00:07:59,909 --> 00:07:58,400
miles in distance

228
00:08:01,749 --> 00:07:59,919
when the shuttle is in close proximity

229
00:08:03,430 --> 00:08:01,759
to hubble on wednesday megan macarthur

230
00:08:05,430 --> 00:08:03,440
will use the shuttle's robot arm to grab

231
00:08:07,270 --> 00:08:05,440
hold of hubble she will then maneuver

232
00:08:10,150 --> 00:08:07,280
the telescope onto the flight support

233
00:08:13,749 --> 00:08:10,160
system or fss platform in atlantis's

234
00:08:15,589 --> 00:08:13,759
payload bay after hubble is on the fss

235
00:08:17,830 --> 00:08:15,599
the first activity will be to orient the

236
00:08:19,990 --> 00:08:17,840
shuttle and telescope so that hubble's

237
00:08:21,350 --> 00:08:20,000
solar arrays can face the sun and

238
00:08:22,950 --> 00:08:21,360
hubble's batteries can get a full

239
00:08:24,950 --> 00:08:22,960
recharge

240
00:08:26,790 --> 00:08:24,960
shortly after that

241
00:08:28,469 --> 00:08:26,800
an external connection from the flight

242
00:08:29,350 --> 00:08:28,479
support system to the telescope will

243
00:08:31,029 --> 00:08:29,360
happen

244
00:08:33,190 --> 00:08:31,039
at that point the telescope's batteries

245
00:08:35,190 --> 00:08:33,200
will be taken offline and hubble will

246
00:08:36,949 --> 00:08:35,200
receive all of its electrical power from

247
00:08:40,469 --> 00:08:36,959
shuttle until just before it is

248
00:08:42,550 --> 00:08:40,479
redeployed on flight day nine so here at

249
00:08:44,790 --> 00:08:42,560
goddard the entire service emission four

250
00:08:46,630 --> 00:08:44,800
team will be anxiously standing by for

251
00:08:48,389 --> 00:08:46,640
their first close-up look at hubble

252
00:08:51,110 --> 00:08:48,399
since the telescope was deployed at the

253
00:08:53,190 --> 00:08:51,120
end of the sts-109 servicing mission in

254
00:08:54,949 --> 00:08:53,200
march two thousand two

255
00:08:57,110 --> 00:08:54,959
we will now return to mission control in

256
00:08:58,630 --> 00:08:57,120
