10
00:00:31,750 --> 00:00:29,279

and mikhail konyenko are scheduled to

27
00:01:20,230 --> 00:01:18,070
students from universities in california

28
00:01:22,390 --> 00:01:20,240
and kentucky built satellites that will

29
00:01:23,350 --> 00:01:22,400
fly on a nasa's suborbital sounding

30
00:01:25,109 --> 00:01:23,360
rocket

31
00:01:27,190 --> 00:01:25,119
the satellites are designed to gather

32
00:01:31,830 --> 00:01:27,200
data for possible use in the development

33
00:01:36,230 --> 00:01:33,590
the students from a consortium of

34
00:01:39,109 --> 00:01:36,240
kentucky universities and cal poly san

35
00:01:41,749 --> 00:01:39,119
luis obispo designed then built the

36
00:01:44,469 --> 00:01:41,759
cubesats using mostly off-the-shelf

37
00:01:46,630 --> 00:01:44,479
components the standard cubesat that's

38
00:01:48,789 --> 00:01:46,640
used for space research is a four-inch

39
00:01:51,350 --> 00:01:48,799
cube weighing about two pounds we're

40
00:01:54,149 --> 00:01:51,360
trying to do is create

41
00:01:56,230 --> 00:01:54,159
a mission that merges the 17-inch

42
00:01:59,270 --> 00:01:56,240
sounding rocket diameter sounding

43
00:02:01,510 --> 00:01:59,280
rockets and nasa wallops with cubesats

44
00:02:04,230 --> 00:02:01,520
which have been flown by educational

45
00:02:05,910 --> 00:02:04,240
university programs for several years

46
00:02:07,990 --> 00:02:05,920
the student cubesats will fly in a

47
00:02:10,630 --> 00:02:08,000
rocket similar to this one from nasa's

48
00:02:13,110 --> 00:02:10,640
wallops flight facility in virginia the

49
00:02:15,510 --> 00:02:13,120
two spacecraft will be ejected 72

50
00:02:18,309 --> 00:02:15,520
seconds into the sub-orbital flight at

51
00:02:20,869 --> 00:02:18,319
an altitude of some 77 miles

52
00:02:22,949 --> 00:02:20,879
nasa is flying the cubesats as secondary

53
00:02:26,790 --> 00:02:22,959
experiments on the flight that'll test

54
00:02:27,830 --> 00:02:26,800
improvements to its rocket's motor

55
00:02:31,270 --> 00:02:27,840
three

56
00:02:33,430 --> 00:02:31,280
two engine start one when liftoff of the

57
00:02:35,750 --> 00:02:33,440
delta ii rocket with kepler it's been a

58
00:02:37,750 --> 00:02:35,760
year since the launch of nasa's kepler

59
00:02:40,470 --> 00:02:37,760
mission from cape canaveral air force

60
00:02:43,509 --> 00:02:40,480
station florida to begin a continuing

61
00:02:45,670 --> 00:02:43,519
survey of our milky way galaxy for signs

62
00:02:47,509 --> 00:02:45,680
of earth-sized planets

63
00:02:49,830 --> 00:02:47,519
since then the kepler spacecraft has

64
00:02:52,790 --> 00:02:49,840
helped scientists discover five planets

65
00:02:54,710 --> 00:02:52,800
beyond our solar system and detect the

66
00:02:57,350 --> 00:02:54,720
atmosphere of another

67
00:02:59,990 --> 00:02:57,360
kepler uses a photometer containing the

68
00:03:02,470 --> 00:03:00,000
largest camera ever flown in space to

69
00:03:04,630 --> 00:03:02,480
document changes in a star's light as a

70
00:03:07,270 --> 00:03:04,640
planet orbiting nearby crosses in front

71
00:03:09,110 --> 00:03:07,280
of it from measurements of these changes

72
00:03:11,670 --> 00:03:09,120
scientists can determine whether these

73
00:03:14,070 --> 00:03:11,680
so-called exoplanets warrant focused

74
00:03:16,790 --> 00:03:14,080
investigation into their suitability for

75
00:03:18,630 --> 00:03:16,800
maintaining life forms in this past year

76
00:03:20,149 --> 00:03:18,640
it's it's like kevlar is a seven course

77
00:03:22,070 --> 00:03:20,159
meal we've just served their jurors

78
00:03:23,990 --> 00:03:22,080
we've announced our first five planets

79
00:03:26,229 --> 00:03:24,000
but you just gotta keep your eyes peeled

80
00:03:27,350 --> 00:03:26,239
and your ears tuned to the news because

81
00:03:29,270 --> 00:03:27,360
the smaller planets are going to be

82
00:03:31,430 --> 00:03:29,280
rolling out the pipeline we just have

83
00:03:33,670 --> 00:03:31,440
patience to find those small planets the

84
00:03:35,589 --> 00:03:33,680
kepler spacecraft nicknamed the planet

85
00:03:39,509 --> 00:03:35,599
finder will continue its scouting

86
00:03:44,630 --> 00:03:42,149
nasa's next space-based observatory the

87
00:03:46,710 --> 00:03:44,640
james webb space telescope was the

88
00:03:49,190 --> 00:03:46,720
featured topic at this year's women's

89
00:03:51,750 --> 00:03:49,200
science forum hosted in baltimore by the

90
00:03:53,750 --> 00:03:51,760
space telescope science institute the

91
00:03:55,509 --> 00:03:53,760
event encouraged young women in middle

92
00:03:57,350 --> 00:03:55,519
and high school to further their

93
00:04:00,710 --> 00:03:57,360
education in the stem disciplines of

94
00:04:03,190 --> 00:04:00,720
science technology engineering and math

95
00:04:05,190 --> 00:04:03,200
46 public private and homeschooled

96
00:04:07,350 --> 00:04:05,200
students from the area participated in

97
00:04:10,070 --> 00:04:07,360
activities and demonstrations centered

98
00:04:13,270 --> 00:04:10,080
on the jwst

99
00:04:15,429 --> 00:04:13,280
planned for launch in 2014 jwst's

100
00:04:17,430 --> 00:04:15,439
instruments will work primarily in the

101
00:04:19,590 --> 00:04:17,440
infrared range of the electromagnetic

102
00:04:21,990 --> 00:04:19,600
spectrum speakers included former

103
00:04:26,830 --> 00:04:22,000
astronaut and institute deputy director

104
00:04:29,189 --> 00:04:26,840
john grunsfeld and jwst scientist tracy

105
00:04:31,110 --> 00:04:29,199
beck informing youngsters and the

106
00:04:33,030 --> 00:04:31,120
general public about nasa's space

107
00:04:35,990 --> 00:04:33,040
communication systems is the goal of a

108
00:04:39,189 --> 00:04:36,000
new interactive 3d computer simulation

109
00:04:41,749 --> 00:04:39,199
available on nasa's website the scan sim

110
00:04:44,629 --> 00:04:41,759
for space communication and navigation

111
00:04:47,030 --> 00:04:44,639
allows virtual explorers to fly through

112
00:04:49,189 --> 00:04:47,040
a 3d tour of nasa's three space

113
00:04:51,510 --> 00:04:49,199
communication networks and learn how

114
00:04:53,670 --> 00:04:51,520
they help scientists and engineers talk

115
00:04:56,230 --> 00:04:53,680
with the mars exploration rover's spirit

116
00:04:58,950 --> 00:04:56,240
and opportunity and other spacecraft

117
00:05:01,590 --> 00:04:58,960
space communication and navigation sends

118
00:05:03,749 --> 00:05:01,600
all of the information that a spacecraft

119
00:05:05,590 --> 00:05:03,759
needs from the earth to the spacecraft

120
00:05:07,590 --> 00:05:05,600
in order to operate and then it

121
00:05:09,270 --> 00:05:07,600
transfers the data that the spacecraft

122
00:05:12,310 --> 00:05:09,280
is collecting whether it's the mars

123
00:05:14,230 --> 00:05:12,320
rover or the space station or others it

124
00:05:15,670 --> 00:05:14,240
sends all that data back to earth so the

125
00:05:18,310 --> 00:05:15,680
scientists and engineers here on earth

126
00:05:21,110 --> 00:05:18,320
can use that visitors can also try a

127
00:05:22,790 --> 00:05:21,120
variety of virtual space experiences

128
00:05:24,390 --> 00:05:22,800
from docking the space shuttle at the

129
00:05:27,510 --> 00:05:24,400
international space station

130
00:05:29,830 --> 00:05:27,520
to taking a trip to mars even exploring

131
00:05:32,550 --> 00:05:29,840
images of star formations taken by the

132
00:05:35,430 --> 00:05:32,560
hubble space telescope all spacecraft

133
00:05:37,590 --> 00:05:35,440
that rely on scan for their success it's

134
00:05:40,670 --> 00:05:37,600
like the cell phone of space check out

135
00:05:44,390 --> 00:05:40,680

nasa scientists drilling through the

138
00:05:59,510 --> 00:05:56,800
thick ice of antarctica's ross ice shelf

139
00:06:01,909 --> 00:05:59,520
last november didn't expect to see this

140
00:06:04,550 --> 00:06:01,919
shrimp-like thing swimming underneath

141
00:06:07,670 --> 00:06:04,560
the creature a three-inch long glycemic

142
00:06:10,629 --> 00:06:07,680
acid amphipod was captured 600 feet

143
00:06:13,029 --> 00:06:10,639
below the west antarctic ice sheet by a

144
00:06:15,189 --> 00:06:13,039
borehole camera lowered through the ice

145
00:06:17,110 --> 00:06:15,199
this was the view looking upwards the

146
00:06:19,110 --> 00:06:17,120
critter was about 12 and a half miles

147
00:06:21,110 --> 00:06:19,120
away from open water

148
00:06:23,430 --> 00:06:21,120
scientists say this is the first time

149
00:06:27,189 --> 00:06:23,440
such a sophisticated life form was found

150
00:06:29,749 --> 00:06:27,199
in this type of sub-glacial environment

151
00:06:32,029 --> 00:06:29,759
and that's this week at nasa for more on
