00:00:07,040 --> 00:00:10,390
this week at nasa

2
00:00:13,509 --> 00:00:12,150
you can see the parachute coming down

3
00:00:16,230 --> 00:00:13,519
and the plume coming out from the soft

4
00:00:18,070 --> 00:00:16,240
landing engines the expedition 35 crew

5
00:00:20,230 --> 00:00:18,080
safely returned from the international

marshburn capped off 146 days in space

14
00:00:43,910 --> 00:00:41,440
full of activity for marshburn some of

15
00:00:46,709 --> 00:00:43,920
it just hours before the crew departed

16
00:00:48,869 --> 00:00:46,719
on may 11 he and fellow nasa astronaut

17
00:00:51,830 --> 00:00:48,879
chris cassidy completed a five-hour

18
00:00:55,029 --> 00:00:51,840
30-minute spacewalk to replace a faulty

19
00:00:56,709 --> 00:00:55,039
coolant pump on the station's p6 truss

20
00:00:59,110 --> 00:00:56,719
the quick turnaround spacewalk was

21
00:01:02,150 --> 00:00:59,120
orchestrated just 48 hours after a

22
00:01:04,229 --> 00:01:02,160
coolant leak developed on p6

23
00:01:06,550 --> 00:01:04,239
and during a nasa tv in flight event on

24
00:01:08,149 --> 00:01:06,560
may 7th mars byrne discussed the work

25
00:01:10,070 --> 00:01:08,159
being done on the international space

26
00:01:11,910 --> 00:01:10,080
station with members of the senate

27
00:01:14,310 --> 00:01:11,920
committee on commerce science and

28
00:01:16,870 --> 00:01:14,320
transportation subcommittee on science

29
00:01:19,190 --> 00:01:16,880
and space chaired by florida senator

30
00:01:21,429 --> 00:01:19,200
bill nelson the subcommittee conducts

31
00:01:23,990 --> 00:01:21,439
oversight of nasa and several other

32
00:01:25,749 --> 00:01:24,000
science and technology related agencies

33
00:01:28,070 --> 00:01:25,759
can you explain how

34
00:01:30,390 --> 00:01:28,080
you know u.s private space companies

35
00:01:31,350 --> 00:01:30,400
uh are using the iss as a technology

36
00:01:33,590 --> 00:01:31,360
platform

37
00:01:35,510 --> 00:01:33,600
if they can do it that is

38
00:01:37,510 --> 00:01:35,520
an incredibly impressive technology

39
00:01:39,510 --> 00:01:37,520
demonstration going into space is not

40
00:01:41,350 --> 00:01:39,520
easy they're coming up with great

41
00:01:43,350 --> 00:01:41,360
efficiencies great new technologies

42
00:01:44,870 --> 00:01:43,360
built on what nasa's already done so

43
00:01:46,950 --> 00:01:44,880
that they can get probably cheaper

44
00:01:49,749 --> 00:01:46,960
better faster get things up to the space

45
00:01:54,789 --> 00:01:51,590
meanwhile the next crew headed to the

46
00:01:56,069 --> 00:01:54,799
space station expedition 3637 soyuz

47
00:01:58,550 --> 00:01:56,079
commander for the order your chicken of

48
00:02:01,109 --> 00:01:58,560
the russian federal space agency nasa

49
00:02:03,190 --> 00:02:01,119
flight engineer karen nyberg and flight

50
00:02:05,510 --> 00:02:03,200
engineer luca parmitano of the european

51
00:02:07,670 --> 00:02:05,520
space agency fielded questions from the

52
00:02:09,589 --> 00:02:07,680
news media as part of their pre-launch

53
00:02:12,390 --> 00:02:09,599
activities at the gagarin cosmonaut

54
00:02:14,309 --> 00:02:12,400
training center in star city russia

55
00:02:17,030 --> 00:02:14,319
the crew is scheduled to travel to the

56
00:02:18,869 --> 00:02:17,040
kazakhstan launch site may 16th to

57
00:02:21,270 --> 00:02:18,879
complete training in advance of its

58
00:02:24,150 --> 00:02:21,280
launch to the station on may 29th local

59
00:02:28,309 --> 00:02:26,150
nasa administrator charlie bolden

60
00:02:30,390 --> 00:02:28,319
delivered opening remarks at the humans

61
00:02:31,509 --> 00:02:30,400
to mars summit at george washington

62
00:02:34,229 --> 00:02:31,519
university

63
00:02:37,430 --> 00:02:34,239
the three-day event held by explore mars

64
00:02:39,670 --> 00:02:37,440
and gw's space policy institute provided

65
00:02:41,670 --> 00:02:39,680
a forum for nasa and the space community

66
00:02:44,150 --> 00:02:41,680
to discuss technical scientific and

67
00:02:46,790 --> 00:02:44,160
policy-related challenges associated

68
00:02:48,790 --> 00:02:46,800
with sending humans to mars by the 2030s

69
00:02:51,509 --> 00:02:48,800
there are technological gaps to sending

70
00:02:53,910 --> 00:02:51,519
humans to an asteroid and to mars

71
00:02:56,229 --> 00:02:53,920
and so every single

72
00:02:58,070 --> 00:02:56,239
moment of our time and every single

73
00:03:00,070 --> 00:02:58,080
dollar of our assets

74
00:03:02,470 --> 00:03:00,080
must be dedicated to developing those

75
00:03:04,550 --> 00:03:02,480
technologies that allow us to go beyond

76
00:03:06,790 --> 00:03:04,560
low earth orbit also discussed the

77
00:03:08,869 --> 00:03:06,800
planned nasa initiative to send humans

78
00:03:11,110 --> 00:03:08,879
to an asteroid and the importance of

79
00:03:12,790 --> 00:03:11,120
work by astronauts during long-duration

80
00:03:15,110 --> 00:03:12,800
missions aboard the international space

81
00:03:17,430 --> 00:03:15,120
station while not specifically designed

82
00:03:19,270 --> 00:03:17,440
to send humans to mars these endeavors

83
00:03:21,509 --> 00:03:19,280
will provide invaluable experience

84
00:03:23,350 --> 00:03:21,519
useful in planning and completing a

85
00:03:25,270 --> 00:03:23,360
successful human journey to the red

86
00:03:26,869 --> 00:03:25,280
planet also we need to think about what

87
00:03:28,789 --> 00:03:26,879
we carry in terms of medical equipment

88
00:03:31,270 --> 00:03:28,799
for the crew other things along those

89
00:03:33,110 --> 00:03:31,280
lines so we get a chance to experience

90
00:03:35,670 --> 00:03:33,120
a different risk environment where we

91
00:03:37,670 --> 00:03:35,680
have you know a protracted return

92
00:03:38,789 --> 00:03:37,680
capability back to the earth and i think

93
00:03:41,750 --> 00:03:38,799
that's what we're going to have to do as

94
00:03:46,949 --> 00:03:44,470
sky lab the nation's first space station

95
00:03:50,229 --> 00:03:46,959
launched the board of saturn 5 rocket 40

96
00:03:52,149 --> 00:03:50,239
years ago on may 14 1973

97
00:03:54,309 --> 00:03:52,159
the three crews that completed missions

98
00:03:56,390 --> 00:03:54,319
aboard the experimental facility not

99
00:03:59,030 --> 00:03:56,400
only set successive new records for long

100
00:04:01,750 --> 00:03:59,040
duration space flight but also completed

101
00:04:03,750 --> 00:04:01,760
about 300 experiments covering physical

102
00:04:06,390 --> 00:04:03,760
and biomedical science and earth and

103
00:04:07,830 --> 00:04:06,400
space applications the skylab program

104
00:04:09,830 --> 00:04:07,840
also yielded knowledge that was

105
00:04:11,830 --> 00:04:09,840
eventually used in development of the

106
00:04:14,470 --> 00:04:11,840
international space station just as the

107
00:04:16,469 --> 00:04:14,480
work being performed on the iss now is

108
00:04:18,469 --> 00:04:16,479
helping nasa develop new missions that

109
00:04:21,990 --> 00:04:18,479
will extend our reach farther into the

110
00:04:23,749 --> 00:04:22,000
solar system as humans move outward into

111
00:04:24,870 --> 00:04:23,759
deeper space exploration we'll probably

112
00:04:27,189 --> 00:04:24,880
learn things that we weren't expecting

113
00:04:30,950 --> 00:04:27,199
to learn just as we did in sky lab in

114
00:04:32,870 --> 00:04:30,960
iss and the next things we do will be

115
00:04:35,749 --> 00:04:32,880
just as astounding as the step from

116
00:04:38,870 --> 00:04:35,759
skylab to iss is after the final crew

117
00:04:41,110 --> 00:04:38,880
left sky lab in february 1974

118
00:04:46,150 --> 00:04:41,120
the empty spacecraft circled the earth

119
00:04:49,350 --> 00:04:47,909
after being incommunicado with the

120
00:04:51,990 --> 00:04:49,360
ground during the recent solar

121
00:04:54,070 --> 00:04:52,000
conjunction the mars curiosity rover is

122
00:04:56,230 --> 00:04:54,080
preparing to get back to wheeling around

123
00:04:58,790 --> 00:04:56,240
the red planet and thanks to a software

124
00:05:01,029 --> 00:04:58,800
update the rover now has the ability to

125
00:05:03,590 --> 00:05:01,039
navigate more on its own

126
00:05:05,909 --> 00:05:03,600
the new autonomous navigation capability

127
00:05:08,870 --> 00:05:05,919
or auto nav enables the rover to

128
00:05:10,870 --> 00:05:08,880
evaluate and select safe paths of travel

129
00:05:11,990 --> 00:05:10,880
with less input from the rover team on

130
00:05:13,990 --> 00:05:12,000
the ground

131
00:05:15,510 --> 00:05:14,000
curiosity also received a software

132
00:05:18,310 --> 00:05:15,520
update to prevent the sensitive

133
00:05:20,629 --> 00:05:18,320
telescopic eye of the chemcam instrument

134
00:05:22,390 --> 00:05:20,639
from being burned by the sun

135
00:05:24,950 --> 00:05:22,400
the update is designed to make sure

136
00:05:26,629 --> 00:05:24,960
kimcam's eye is never pointed directly

137
00:05:28,870 --> 00:05:26,639
at the sun

138
00:05:30,469 --> 00:05:28,880
and the rover team is also confirming

139
00:05:32,629 --> 00:05:30,479
the calibration of curiosity's

140
00:05:34,070 --> 00:05:32,639
navigation cameras before driving to a

141
00:05:36,070 --> 00:05:34,080
new location

142
00:05:38,469 --> 00:05:36,080
plans are in the works for a short drive

143
00:05:40,230 --> 00:05:38,479
to a new drill site called cumberland

144
00:05:42,629 --> 00:05:40,240
about nine feet west of where

145
00:05:46,469 --> 00:05:42,639
curiosity's drill first touched martian

two decades

152
00:06:05,270 --> 00:06:02,639
each frame of the time lapse is

153
00:06:08,710 --> 00:06:05,280
constructed from a year of landsat data

154
00:06:10,070 --> 00:06:08,720

geological survey the landsat program

158
00:06:20,230 --> 00:06:16,960
has acquired images of the earth's

159
00:06:21,909 --> 00:06:20,240
surface since 1972 providing critical

160
00:06:23,830 --> 00:06:21,919
scientific information about our

00:06:35,830 --> 00:06:31,350
intro

163
00:06:41,430 --> 00:06:38,870
these bugs flightless fruit flies may

164
00:06:42,550 --> 00:06:41,440
someday help make airplanes more fuel

165
00:06:44,150 --> 00:06:42,560
efficient

166
00:06:46,230 --> 00:06:44,160
their work starts in a wind tunnel at

167
00:06:48,469 --> 00:06:46,240
nasa's langley research center where

168
00:06:50,390 --> 00:06:48,479
technicians install the edge of a wing

169
00:06:52,710 --> 00:06:50,400
that's covered with a special coating

170
00:06:55,189 --> 00:06:52,720
the task is to

171
00:06:57,189 --> 00:06:55,199
design a surface that prevents insect

172
00:06:59,029 --> 00:06:57,199
residues from sticking okay and the

173
00:07:01,270 --> 00:06:59,039
reason is

174
00:07:04,150 --> 00:07:01,280
that if you have any residue sticking it

175
00:07:06,790 --> 00:07:04,160
trips the airflow over it rough airflow

176
00:07:08,790 --> 00:07:06,800
increases airplane fuel usage as much as

177
00:07:10,950 --> 00:07:08,800
30 percent says nasa's environmentally

responsible aviation project between the

179
00:07:14,870 --> 00:07:12,560
commercial coatings you've looked at and

180
00:07:17,029 --> 00:07:14,880
new coatings or and surfaces that we've

181
00:07:18,950 --> 00:07:17,039
engineered and modified we've looked at

182
00:07:22,390 --> 00:07:18,960
about 60 different

183
00:07:23,990 --> 00:07:22,400
surfaces for the bugs it's up close

184
00:07:27,110 --> 00:07:24,000
they're launched at the coated wing at

185
00:07:29,430 --> 00:07:27,120
about 150 miles an hour the researchers

186
00:07:30,390 --> 00:07:29,440
goal to narrow the field of coatings to

187
00:07:32,309 --> 00:07:30,400
a few

188
00:07:40,309 --> 00:07:32,319
that are effective enough to test on an

189
00:07:45,350 --> 00:07:42,830
