1
00:00:10,310 --> 00:00:08,310
endeavors astronauts wrap up their

2
00:00:12,310 --> 00:00:10,320
experiments pack up their ship and head

3
00:00:13,990 --> 00:00:12,320
into the home stretch of their journey a

4
00:00:15,829 --> 00:00:14,000
look back at the mission and a look

5
00:00:17,910 --> 00:00:15,839
ahead to landing in the pre-dawn hours

6
00:00:19,590 --> 00:00:17,920
tomorrow we've got the details of the

7
00:00:21,670 --> 00:00:19,600
final hours of the first shuttle flight

8
00:00:35,670 --> 00:00:21,680
of the year next on the flight day 9

9
00:00:39,830 --> 00:00:37,510
welcome to mission update

10
00:00:41,430 --> 00:00:39,840
now less than 17 hours away from a

11
00:00:43,430 --> 00:00:41,440
scheduled nighttime landing at the

12
00:00:45,750 --> 00:00:43,440
kennedy space center the astronauts

13
00:00:47,750 --> 00:00:45,760
aboard endeavour are set for sleep after

14
00:00:49,910 --> 00:00:47,760
a day of deactivating secondary

15
00:00:52,389 --> 00:00:49,920
experiments packing up their equipment

16
00:00:54,150 --> 00:00:52,399
and testing the orbiter's flight systems

17
00:00:55,910 --> 00:00:54,160
late last night the six astronauts

18
00:00:58,470 --> 00:00:55,920
gathered to respond to reporters

19
00:01:00,549 --> 00:00:58,480
questions both in english and japanese

20
00:01:02,630 --> 00:01:00,559
about the achievements of their mission

21
00:01:04,549 --> 00:01:02,640
those include the successful retrieval

22
00:01:06,630 --> 00:01:04,559
of the japanese space flier unit

23
00:01:08,950 --> 00:01:06,640
satellite the deployment and retrieval

24
00:01:10,950 --> 00:01:08,960
of the oastflyer satellite and two

25
00:01:13,030 --> 00:01:10,960
spacewalks which contributed more than a

26
00:01:14,950 --> 00:01:13,040
day's worth of experience in working in

27
00:01:17,190 --> 00:01:14,960
a weightless environment and testing

28
00:01:18,789 --> 00:01:17,200
construction tools and techniques being

29
00:01:19,749 --> 00:01:18,799
planned for the international space

30
00:01:22,230 --> 00:01:19,759
station

31
00:01:24,149 --> 00:01:22,240
right now endeavour is flying some 190

32
00:01:27,109 --> 00:01:24,159
miles over the pacific ocean near the

33
00:01:29,510 --> 00:01:27,119
hawaiian islands on the 131st orbit of

34
00:01:32,550 --> 00:01:29,520
the mission traveling at 17

35
00:01:34,630 --> 00:01:32,560
500 miles an hour or five miles a second

36
00:01:35,590 --> 00:01:34,640
it circles the earth once every 90

37
00:01:37,590 --> 00:01:35,600
minutes

38
00:01:39,749 --> 00:01:37,600
having completed packing up all the

39
00:01:41,910 --> 00:01:39,759
equipment in the crew cabin all six

40
00:01:43,990 --> 00:01:41,920
astronauts are in their pre-sleep period

41
00:01:46,149 --> 00:01:44,000
now in fact they are scheduled to go to

42
00:01:48,149 --> 00:01:46,159
sleep for the last time this mission at

43
00:01:50,069 --> 00:01:48,159
9 11.

44
00:01:51,990 --> 00:01:50,079
since getting up yesterday afternoon the

45
00:01:53,670 --> 00:01:52,000
astronauts focused on ensuring that

46
00:01:55,910 --> 00:01:53,680
everything with their ship is set to

47
00:01:58,149 --> 00:01:55,920
come home tomorrow morning they also

48
00:01:59,830 --> 00:01:58,159
took time out a little time out to share

49
00:02:02,709 --> 00:01:59,840
their thoughts about the mission with

50
00:02:04,230 --> 00:02:02,719
reporters on the ground

51
00:02:05,990 --> 00:02:04,240
with their mission nearing an end

52
00:02:07,990 --> 00:02:06,000
endeavors astronauts began what is

53
00:02:10,150 --> 00:02:08,000
expected to be their final full day in

54
00:02:21,190 --> 00:02:10,160
space last night with a wake-up call

55
00:02:24,790 --> 00:02:22,869
the theme from the motion picture star

56
00:02:26,630 --> 00:02:24,800
wars sent the astronauts off and running

57
00:02:29,270 --> 00:02:26,640
to prepare for saturday's scheduled

58
00:02:30,790 --> 00:02:29,280
landing commander brian duffy and pilot

59
00:02:32,949 --> 00:02:30,800
brent jett took their seats on the

60
00:02:35,350 --> 00:02:32,959
flight deck to conduct routine tests of

61
00:02:38,070 --> 00:02:35,360
endeavor's flight control systems they

62
00:02:39,830 --> 00:02:38,080
then fired endeavour's 44 steering jets

63
00:02:41,509 --> 00:02:39,840
two of which failed but flight

64
00:02:43,509 --> 00:02:41,519
controllers said backup jets would be

65
00:02:45,910 --> 00:02:43,519
used during entry with no impact to the

66
00:02:48,070 --> 00:02:45,920
ship's landing as the astronauts began

67
00:02:49,750 --> 00:02:48,080
to pack up their ship flight controllers

68
00:02:50,949 --> 00:02:49,760
told duffy that weather conditions at

69
00:02:52,949 --> 00:02:50,959
the cape were looking good for

70
00:02:54,710 --> 00:02:52,959
tomorrow's homecoming

71
00:02:57,830 --> 00:02:54,720
what we've got is we've got some great

72
00:03:00,309 --> 00:02:57,840
weather for you both saturday and sunday

73
00:03:03,270 --> 00:03:00,319
at both landing sites

74
00:03:04,710 --> 00:03:03,280
we will be bringing up ksc only on

75
00:03:07,830 --> 00:03:04,720
saturday

76
00:03:09,750 --> 00:03:07,840
with two opportunities there

77
00:03:11,589 --> 00:03:09,760
midway through their day the astronauts

78
00:03:13,750 --> 00:03:11,599
began to shut down some of endeavour's

79
00:03:15,830 --> 00:03:13,760
secondary experiments including the

80
00:03:17,830 --> 00:03:15,840
shuttle laser altimeter payload in the

81
00:03:19,670 --> 00:03:17,840
cargo bay the experiment has been

82
00:03:21,750 --> 00:03:19,680
collecting data on topographical

83
00:03:23,589 --> 00:03:21,760
features on earth and measuring the

84
00:03:25,670 --> 00:03:23,599
distance between the shuttle and those

85
00:03:27,670 --> 00:03:25,680
land masses

86
00:03:29,589 --> 00:03:27,680
before stowing endeavour's ku band

87
00:03:31,190 --> 00:03:29,599
antenna the crew gathered on the flight

88
00:03:34,149 --> 00:03:31,200
deck to answer questions about their

89
00:03:36,309 --> 00:03:34,159
mission from u.s and japanese reporters

90
00:03:38,070 --> 00:03:36,319
astronauts leroy chao and winston scott

91
00:03:40,149 --> 00:03:38,080
discussed the spacewalks conducted

92
00:03:42,149 --> 00:03:40,159
earlier this week improvements made to

93
00:03:43,910 --> 00:03:42,159
their spacesuits and the effect the

94
00:03:46,229 --> 00:03:43,920
spacewalks will have on the assembly of

95
00:03:48,070 --> 00:03:46,239
the international space station but

96
00:03:50,149 --> 00:03:48,080
overall i felt very good in the suit i

97
00:03:52,470 --> 00:03:50,159
could have continued to work in the suit

98
00:03:54,149 --> 00:03:52,480
regardless of the uh temperatures so i

99
00:03:56,229 --> 00:03:54,159
would say with we certainly have a good

100
00:03:58,789 --> 00:03:56,239
baseline for which we can

101
00:04:00,630 --> 00:03:58,799
uh going and do our work obviously you

102
00:04:02,149 --> 00:04:00,640
always want to look for improvements but

103
00:04:04,470 --> 00:04:02,159
i think we're to the point where we can

104
00:04:06,309 --> 00:04:04,480
take that suit airborne and begin to

105
00:04:07,830 --> 00:04:06,319
construct the station with it it was a

106
00:04:09,350 --> 00:04:07,840
very successful flight test we learned a

107
00:04:11,509 --> 00:04:09,360
lot it's going to feed right back into

108
00:04:14,869 --> 00:04:11,519
the space station and the space station

109
00:04:16,550 --> 00:04:14,879
program and we're ready to go build it

110
00:04:18,789 --> 00:04:16,560
endeavour's landing will be the eighth

111
00:04:21,509 --> 00:04:18,799
in darkness in shuttle history but duffy

112
00:04:23,189 --> 00:04:21,519
said not to worry i'm looking forward to

113
00:04:24,629 --> 00:04:23,199
the night landing it's something that

114
00:04:26,230 --> 00:04:24,639
we've trained for

115
00:04:27,510 --> 00:04:26,240
brent and i have been training now for

116
00:04:28,390 --> 00:04:27,520
the you know the better part of a year

117
00:04:30,150 --> 00:04:28,400
to do that

118
00:04:31,030 --> 00:04:30,160
uh we've flown hundreds of approaches at

119
00:04:33,430 --> 00:04:31,040
night

120
00:04:35,270 --> 00:04:33,440
um i don't think that it'll be all that

121
00:04:37,270 --> 00:04:35,280
different from uh from a day landing to

122
00:04:39,350 --> 00:04:37,280
tell you the truth that some people that

123
00:04:40,469 --> 00:04:39,360
have made knight landings before tell me

124
00:04:41,590 --> 00:04:40,479
that it's actually a little bit easier

125
00:04:44,469 --> 00:04:41,600
just because you don't have all the

126
00:04:45,909 --> 00:04:44,479
other things in your visual

127
00:04:47,670 --> 00:04:45,919
current range

128
00:04:49,590 --> 00:04:47,680
uh to distract you at all and all you

129
00:04:51,030 --> 00:04:49,600
have is the lit runway and the center

130
00:04:53,030 --> 00:04:51,040
line and the light sliding up the

131
00:04:54,310 --> 00:04:53,040
touchdown zone so very excited about

132
00:04:55,430 --> 00:04:54,320
doing it i've been training for it for a

133
00:04:56,790 --> 00:04:55,440
long time

134
00:04:58,790 --> 00:04:56,800
and i don't think it's going to be

135
00:05:00,790 --> 00:04:58,800
particularly difficult

136
00:05:03,749 --> 00:05:00,800
to learn about the latest preparations

137
00:05:05,430 --> 00:05:03,759
for the conclusion of mission sts 72 we

138
00:05:07,430 --> 00:05:05,440
talked to mission operations director

139
00:05:09,350 --> 00:05:07,440
lee briscoe in mission control earlier

140
00:05:11,189 --> 00:05:09,360
today i asked him if everything was

141
00:05:13,189 --> 00:05:11,199
proceeding on schedule for a landing

142
00:05:14,950 --> 00:05:13,199
tomorrow morning

143
00:05:16,790 --> 00:05:14,960
everything really is on schedule for

144
00:05:18,310 --> 00:05:16,800
landing tomorrow morning the flight's

145
00:05:20,390 --> 00:05:18,320
gone very well we're all looking forward

146
00:05:22,230 --> 00:05:20,400
to landing at ksc tomorrow

147
00:05:25,110 --> 00:05:22,240
what about the weather lee are there any

148
00:05:27,270 --> 00:05:25,120
concerns about conditions at ksc or at

149
00:05:28,790 --> 00:05:27,280
edwards for a possible landing there

150
00:05:30,390 --> 00:05:28,800
the weather's looking pretty good there

151
00:05:31,909 --> 00:05:30,400
are two frontal systems one on each

152
00:05:33,749 --> 00:05:31,919
coast that we're watching

153
00:05:35,110 --> 00:05:33,759
the one on the east coast at ksc should

154
00:05:37,029 --> 00:05:35,120
clear and that should give us just

155
00:05:39,430 --> 00:05:37,039
scattered clouds and wind right down the

156
00:05:40,790 --> 00:05:39,440
runway so that looks good at edwards the

157
00:05:43,029 --> 00:05:40,800
other front's out there and there may be

158
00:05:44,469 --> 00:05:43,039
a bit of a crosswind problem so we'll

159
00:05:46,550 --> 00:05:44,479
have to watch that but it generally

160
00:05:48,390 --> 00:05:46,560
looks really good for tomorrow

161
00:05:50,310 --> 00:05:48,400
if for some reason you should have to

162
00:05:51,990 --> 00:05:50,320
wave off tomorrow morning what are the

163
00:05:53,510 --> 00:05:52,000
next options and how long could

164
00:05:55,430 --> 00:05:53,520
endeavour stay up

165
00:05:57,110 --> 00:05:55,440
well we have a number of options again

166
00:06:00,070 --> 00:05:57,120
we'll have a number of opportunities to

167
00:06:00,870 --> 00:06:00,080
ksc and edwards on sunday morning uh and

168
00:06:02,790 --> 00:06:00,880
then we'll have a number of

169
00:06:04,790 --> 00:06:02,800
opportunities after that

170
00:06:06,390 --> 00:06:04,800
we actually have consumables on board to

171
00:06:08,230 --> 00:06:06,400
allow us to go uh

172
00:06:10,230 --> 00:06:08,240
four or five days out instead of the

173
00:06:11,510 --> 00:06:10,240
normal two days but we'll be talking

174
00:06:13,749 --> 00:06:11,520
that over with the mission management

175
00:06:15,749 --> 00:06:13,759
team this morning and coming up with our

176
00:06:18,230 --> 00:06:15,759
plan on what we want to do

177
00:06:20,550 --> 00:06:18,240
that's sts-72 mission operations

178
00:06:22,550 --> 00:06:20,560
director lee briscoe

179
00:06:24,710 --> 00:06:22,560
now here's a look ahead at the final

180
00:06:27,590 --> 00:06:24,720
hours of this flight of endeavor and our

181
00:06:29,350 --> 00:06:27,600
coverage plans here on nasa tv

182
00:06:31,189 --> 00:06:29,360
at 10 central time we'll bring you

183
00:06:33,350 --> 00:06:31,199
today's mission status briefing from

184
00:06:35,510 --> 00:06:33,360
here at the johnson space center and at

185
00:06:37,749 --> 00:06:35,520
11 30 we'll follow with the flight day

186
00:06:39,590 --> 00:06:37,759
video file the highlights of the past

187
00:06:41,909 --> 00:06:39,600
day aboard endeavour

188
00:06:44,150 --> 00:06:41,919
