1
00:00:07,680 --> 00:00:11,430
this week at nasa

2
00:00:15,829 --> 00:00:13,589
it was a week full of activity for the

3
00:00:17,750 --> 00:00:15,839
crews of the international space station

4
00:00:21,750 --> 00:00:17,760
it is time for expedition 30 to step

5
00:00:24,070 --> 00:00:21,760
aside and make way for expedition 31.

6
00:00:25,509 --> 00:00:24,080
i'll egg with that i hereby hand over

7
00:00:27,509 --> 00:00:25,519
command of the international space

8
00:00:29,509 --> 00:00:27,519
station to you

9
00:00:31,830 --> 00:00:29,519
nasa astronaut and expedition 30

10
00:00:33,670 --> 00:00:31,840
commander dan burbank officially

11
00:00:36,229 --> 00:00:33,680
transferred the helm of the orbiting

12
00:00:38,950 --> 00:00:36,239
outpost to russian cosmonaut oleg

13
00:00:41,430 --> 00:00:38,960
kononenko who along with nasa astronaut

14
00:00:44,150 --> 00:00:41,440
don pettit and andre kuipers of the

15
00:00:45,990 --> 00:00:44,160
european space agency has now begun

16
00:00:48,150 --> 00:00:46,000
expedition 31.

17
00:00:50,069 --> 00:00:48,160
two days later burbank and his

18
00:00:52,950 --> 00:00:50,079
expedition 30 crewmates russian

19
00:00:54,069 --> 00:00:52,960
cosmonaut anton shkaplerov and anatoly

20
00:00:56,229 --> 00:00:54,079
ivanishin

21
00:00:59,590 --> 00:00:56,239
said their farewells climbed into their

22
00:01:08,070 --> 00:00:59,600
soyuz tma-22 spacecraft and departed the

23
00:01:11,429 --> 00:01:09,830
after a five and a half month stay on

24
00:01:14,310 --> 00:01:11,439
board the iss

25
00:01:17,590 --> 00:01:14,320
burbank chicago and ivanishin landed

26
00:01:19,590 --> 00:01:17,600
safely in kazakhstan

27
00:01:21,429 --> 00:01:19,600
what's been really nice is that you know

28
00:01:23,350 --> 00:01:21,439
coming from the united states of course

29
00:01:25,590 --> 00:01:23,360
the cultures are different the language

30
00:01:27,990 --> 00:01:25,600
is difficult and everyone here has been

31
00:01:29,109 --> 00:01:28,000
very very patient with us

32
00:01:31,429 --> 00:01:29,119
and making sure that we're going to be

33
00:01:33,429 --> 00:01:31,439
ready for our flight meanwhile the other

34
00:01:35,030 --> 00:01:33,439
three members of expedition 31

35
00:01:36,230 --> 00:01:35,040
participated in their pre-launch

36
00:01:38,469 --> 00:01:36,240
activities

37
00:01:41,190 --> 00:01:38,479
at the gagarin cosmonaut training center

38
00:01:43,510 --> 00:01:41,200
in star city russia nasa flight engineer

39
00:01:45,990 --> 00:01:43,520
joe acaba and his russian crewmates

40
00:01:48,149 --> 00:01:46,000
soyuz commander gennady padalka and

41
00:01:50,310 --> 00:01:48,159
flight engineer sergey revin fielded

42
00:01:51,910 --> 00:01:50,320
questions from reporters

43
00:01:53,910 --> 00:01:51,920
the trio is undergoing final

44
00:01:55,749 --> 00:01:53,920
qualification training for the soyuz

45
00:01:58,789 --> 00:01:55,759
vehicle that's scheduled to launch them

46
00:02:00,870 --> 00:01:58,799
to the iss on may 15 and their

47
00:02:05,190 --> 00:02:00,880
subsequent rendezvous on orbit with

48
00:02:09,910 --> 00:02:07,270
the week after it was made it to nasa's

49
00:02:12,550 --> 00:02:09,920
shuttle carrier aircraft enterprise

50
00:02:14,470 --> 00:02:12,560
nasa's first orbiter was lifted skyward

51
00:02:16,229 --> 00:02:14,480
on the shuttle's final ferry flight from

52
00:02:24,470 --> 00:02:16,239
washington's dulles international

53
00:02:27,589 --> 00:02:25,990
several hours later in a site

54
00:02:30,790 --> 00:02:27,599
reminiscent of its flyer round of the

55
00:02:33,350 --> 00:02:30,800
washington dc metro area a week earlier

56
00:02:35,670 --> 00:02:33,360
the sca brought enterprise over several

57
00:02:37,270 --> 00:02:35,680
big apple landmarks before finally

58
00:02:39,030 --> 00:02:37,280
touching down at john f kennedy

59
00:02:42,070 --> 00:02:39,040
international airport

60
00:02:44,229 --> 00:02:42,080
enterprise will remain at jfk until july

61
00:02:46,390 --> 00:02:44,239
when it's scheduled to barge its way up

62
00:02:48,869 --> 00:02:46,400
the hudson river to its new permanent

63
00:02:51,589 --> 00:02:48,879
home the intrepid sea air and space

64
00:02:53,190 --> 00:02:51,599
museum the space program is alive and

65
00:02:55,750 --> 00:02:53,200
well because of the space shuttle

66
00:02:58,309 --> 00:02:55,760
enterprise and what she has brought to

67
00:03:01,910 --> 00:02:58,319
this nation and we are so

68
00:03:04,149 --> 00:03:01,920
pleased that you will at the intrepid

69
00:03:07,430 --> 00:03:04,159
continue to tell not only the story of

70
00:03:11,270 --> 00:03:07,440
the past but this rich and full

71
00:03:14,949 --> 00:03:13,110
scientists working with images from

72
00:03:17,270 --> 00:03:14,959
nasa's cassini spacecraft have

73
00:03:20,390 --> 00:03:17,280
discovered strange half-mile sized

74
00:03:22,390 --> 00:03:20,400
objects punching through saturn's f or

75
00:03:24,390 --> 00:03:22,400
outermost main ring

76
00:03:26,710 --> 00:03:24,400
these objects appear to collide with the

77
00:03:29,430 --> 00:03:26,720
f ring at about four miles per hour

78
00:03:31,830 --> 00:03:29,440
leaving behind so-called mini jets

79
00:03:34,470 --> 00:03:31,840
glittering trails of ice particles from

80
00:03:36,470 --> 00:03:34,480
20 to 110 miles long

81
00:03:39,030 --> 00:03:36,480
scientists have known relatively large

82
00:03:41,750 --> 00:03:39,040
objects can create channels ripples and

83
00:03:43,030 --> 00:03:41,760
snowballs or clumps of icy materials in

84
00:03:45,270 --> 00:03:43,040
the f ring

85
00:03:46,949 --> 00:03:45,280
however they didn't know what happened

86
00:03:48,149 --> 00:03:46,959
to these snowballs after they were

87
00:03:49,990 --> 00:03:48,159
created

88
00:03:51,910 --> 00:03:50,000
some were broken up by collisions or

89
00:03:52,949 --> 00:03:51,920
tidal forces in their orbit around

90
00:03:54,630 --> 00:03:52,959
saturn

91
00:03:57,190 --> 00:03:54,640
now it appears that some of these

92
00:03:59,110 --> 00:03:57,200
smaller snowballs survived with their

93
00:04:03,350 --> 00:03:59,120
differing orbits directing them through

94
00:04:07,670 --> 00:04:05,190
on a sunny spring morning the crew of

95
00:04:09,270 --> 00:04:07,680
the freedom star gets ready to head out

96
00:04:10,229 --> 00:04:09,280
from the cape canaveral air force

97
00:04:12,550 --> 00:04:10,239
station

98
00:04:13,910 --> 00:04:12,560
all lines are in ready to park dock

99
00:04:15,670 --> 00:04:13,920
get underway

100
00:04:17,509 --> 00:04:15,680
it's nasa mission

101
00:04:18,949 --> 00:04:17,519
training for the dawn of a new day in

102
00:04:20,629 --> 00:04:18,959
space travel

103
00:04:22,950 --> 00:04:20,639
capturing the launch of the first

104
00:04:24,950 --> 00:04:22,960
commercial spacecraft going to the

105
00:04:26,870 --> 00:04:24,960
international space station

106
00:04:29,110 --> 00:04:26,880
very similar to what you see in front of

107
00:04:30,870 --> 00:04:29,120
your high definition television set at

108
00:04:32,629 --> 00:04:30,880
home we're looking at getting very high

109
00:04:35,110 --> 00:04:32,639
spatial resolution high definition

110
00:04:36,310 --> 00:04:35,120
quality of visual imaging during the

111
00:04:37,510 --> 00:04:36,320
launch

112
00:04:39,749 --> 00:04:37,520
as well as

113
00:04:42,550 --> 00:04:39,759
high spatial resolution thermal imaging

114
00:04:44,310 --> 00:04:42,560
from an infrared camera the freedom star

115
00:04:46,950 --> 00:04:44,320
once used to recover shuttle rocket

116
00:04:49,670 --> 00:04:46,960
boosters is now outfitted as a floating

117
00:04:52,469 --> 00:04:49,680
high-tech radar and camera platform

118
00:04:55,430 --> 00:04:52,479
inside a huge metal clam shell is a

119
00:04:57,189 --> 00:04:55,440
mobile optical system on a gyroscope

120
00:04:59,350 --> 00:04:57,199
like tracking mount

121
00:05:01,990 --> 00:04:59,360
during launch the system will be focused

122
00:05:05,270 --> 00:05:02,000
skyward to take images of the spacex

123
00:05:07,830 --> 00:05:05,280
falcon rocket and its dragon capsule as

124
00:05:09,670 --> 00:05:07,840
far as 200 miles away

125
00:05:11,350 --> 00:05:09,680
we have several key events that will

126
00:05:14,469 --> 00:05:11,360
occur during ascent

127
00:05:16,469 --> 00:05:14,479
so we have one ground station

128
00:05:19,590 --> 00:05:16,479
at daytona beach florida that will

129
00:05:22,310 --> 00:05:19,600
capture early events and ascent and then

130
00:05:24,390 --> 00:05:22,320
we have a second

131
00:05:26,310 --> 00:05:24,400
tracker that will be located on a ship

132
00:05:28,310 --> 00:05:26,320
in the north atlantic that will be the

133
00:05:30,550 --> 00:05:28,320
freedom star that will capture later

134
00:05:33,510 --> 00:05:30,560
parts of the trip including deployments

135
00:05:35,830 --> 00:05:33,520
of the capsule and solar panels

136
00:05:36,950 --> 00:05:35,840
even with high-powered radar telescopes

137
00:05:38,550 --> 00:05:36,960
and cameras

138
00:05:40,469 --> 00:05:38,560
and a team that has had success in

139
00:05:43,029 --> 00:05:40,479
taking thermal snapshots of the space

140
00:05:46,310 --> 00:05:43,039
shuttle at mach 18

141
00:05:47,990 --> 00:05:46,320
imaging the launch will be no easy task

142
00:05:49,270 --> 00:05:48,000
it's like standing and looking through a

143
00:05:51,510 --> 00:05:49,280
soda straw and

144
00:05:53,590 --> 00:05:51,520
trying to capture and see a bird flying

145
00:05:56,309 --> 00:05:53,600
through that soda straw then imagine

146
00:05:58,710 --> 00:05:56,319
that soda straw bobbing on a boat off

147
00:06:01,189 --> 00:05:58,720
the northeastern coast of the u.s and

148
00:06:02,870 --> 00:06:01,199
seas that could swell up to 20 feet

149
00:06:05,029 --> 00:06:02,880
the crew can only hope that the weather

150
00:06:11,110 --> 00:06:05,039
at launch and ascent is more like a day

151
00:06:15,270 --> 00:06:13,270
nasa administrator charles bolden and

152
00:06:17,749 --> 00:06:15,280
small business programs associate

153
00:06:20,309 --> 00:06:17,759
administrator glenn delgado seen here on

154
00:06:22,469 --> 00:06:20,319
the far right presented the annual small

155
00:06:25,189 --> 00:06:22,479
business administrators cup award to

156
00:06:27,670 --> 00:06:25,199
stennis space center in recognition of

157
00:06:30,150 --> 00:06:27,680
its stellar small business program

158
00:06:32,309 --> 00:06:30,160
the award recognizes successful and

159
00:06:34,469 --> 00:06:32,319
innovative practices promoting small

160
00:06:37,430 --> 00:06:34,479
business participation in nasa

161
00:06:41,270 --> 00:06:39,749
nasa astronaut katie coleman a member of

162
00:06:44,309 --> 00:06:41,280
the international space station's

163
00:06:46,790 --> 00:06:44,319
expedition 27 crew participated in the

164
00:06:48,390 --> 00:06:46,800
white house council on women and girls

165
00:06:50,309 --> 00:06:48,400
in stem event

166
00:06:52,870 --> 00:06:50,319
the panel discussion focused on

167
00:06:55,430 --> 00:06:52,880
inspiring and encouraging young women to

168
00:06:57,189 --> 00:06:55,440
pursue careers in science technology

169
00:06:59,189 --> 00:06:57,199
engineering and math

170
00:07:01,110 --> 00:06:59,199
coleman and the other guests shared

171
00:07:03,029 --> 00:07:01,120
stories about some of the cool things

172
00:07:05,110 --> 00:07:03,039
they've experienced in their stem

173
00:07:07,350 --> 00:07:05,120
related jobs i love this picture because

174
00:07:09,589 --> 00:07:07,360
it is a picture of a human being

175
00:07:10,710 --> 00:07:09,599
in space looking back at the planet we

176
00:07:12,230 --> 00:07:10,720
come from

177
00:07:14,309 --> 00:07:12,240
and there's no way

178
00:07:15,510 --> 00:07:14,319
that only guys should be in a picture

179
00:07:17,110 --> 00:07:15,520
like this

180
00:07:18,950 --> 00:07:17,120
it's all and i'm not saying that to be

181
00:07:21,990 --> 00:07:18,960
funny i know i mean it kind of is but

182
00:07:23,909 --> 00:07:22,000
it's because we are part of the planet

183
00:07:25,909 --> 00:07:23,919
and we bring a lot to the planet and if

184
00:07:28,550 --> 00:07:25,919
you start doing things without the

185
00:07:30,390 --> 00:07:28,560
talents that we women bring you are just

186
00:07:32,070 --> 00:07:30,400
not doing them good enough so did you

187
00:07:33,830 --> 00:07:32,080
play the game or you designed the game i

188
00:07:35,830 --> 00:07:33,840
designed it you designed the game the

189
00:07:38,230 --> 00:07:35,840
event also included the first public

190
00:07:40,150 --> 00:07:38,240
