00:01:33,990 --> 00:01:31,600
heat shield as it re-enters earth's

38
00:01:36,149 --> 00:01:34,000
atmosphere at high speeds similar to

39
00:01:39,429 --> 00:01:36,159

conference in flagstaff arizona

51
00:02:12,229 --> 00:02:09,920
the five-day event addressed strategies

52
00:02:15,110 --> 00:02:12,239
for deflecting an asteroid and civil

53
00:02:16,790 --> 00:02:15,120
defense response should impact threaten

54
00:02:18,150 --> 00:02:16,800
well nasa's all about

55
00:02:19,510 --> 00:02:18,160
leaving the world a better place so

56
00:02:21,589 --> 00:02:19,520
leaving it

57
00:02:23,589 --> 00:02:21,599
intact is a is a good benefit that we

58
00:02:26,309 --> 00:02:23,599
can help with also included was an

59
00:02:28,229 --> 00:02:26,319
outing to nearby meteor crater one of

60
00:02:32,150 --> 00:02:28,239
the best preserved meteorite impact

61
00:02:36,869 --> 00:02:34,470
nasa's kepler space telescope has

62
00:02:39,509 --> 00:02:36,879
discovered three super-earth-sized

63
00:02:41,910 --> 00:02:39,519
planets in their star's habitable zones

64
00:02:43,670 --> 00:02:41,920
a region where liquid water might exist

65
00:02:45,509 --> 00:02:43,680
on the planet's surface

66
00:02:47,589 --> 00:02:45,519
the smallest of the three is only forty

67
00:02:50,309 --> 00:02:47,599
percent larger than earth and most

68
00:02:53,270 --> 00:02:50,319
likely rocky in composition two of the

69
00:02:56,229 --> 00:02:53,280
planets orbit a star known as kepler-62

70
00:02:58,949 --> 00:02:56,239
located 360 light years from earth

71
00:03:01,589 --> 00:02:58,959
the other revolves around kepler-69

72
00:03:04,470 --> 00:03:01,599
which is approximately 2 700 light years

73
00:03:06,550 --> 00:03:04,480
away

74
00:03:08,710 --> 00:03:06,560
aboard the international space station a

75
00:03:11,589 --> 00:03:08,720
spacewalk by russian flight engineers

76
00:03:13,589 --> 00:03:11,599
pavel vinogradov and roman romanenko to

77
00:03:15,910 --> 00:03:13,599
deploy and retrieve several science

78
00:03:18,070 --> 00:03:15,920
experiments and install a new

79
00:03:19,030 --> 00:03:18,080
navigational aid on the zvezda service

80
00:03:21,190 --> 00:03:19,040
module

81
00:03:23,030 --> 00:03:21,200
the retro reflector device will provide

82
00:03:25,270 --> 00:03:23,040
docking assistance for the arrival of

83
00:03:27,830 --> 00:03:25,280
the european space agency's albert

84
00:03:30,869 --> 00:03:27,840
einstein automated transfer vehicle for

85
00:03:33,509 --> 00:03:30,879
cargo ship in june the spacewalk the

86
00:03:35,750 --> 00:03:33,519
160c in support of space station

87
00:03:37,589 --> 00:03:35,760
assembly and maintenance is the seventh

88
00:03:41,110 --> 00:03:37,599
for vinogradov and the first for

89
00:03:44,710 --> 00:03:42,789
teams of high school and college

90
00:03:47,430 --> 00:03:44,720
students are geared up for the 20th

91
00:03:50,470 --> 00:03:47,440
annual great moon buggy race april 25th

92
00:03:52,149 --> 00:03:50,480
through 27th at the u.s space and rocket

93
00:03:53,750 --> 00:03:52,159
center in huntsville

94
00:03:56,149 --> 00:03:53,760
hosted by the marshall space flight

95
00:03:58,550 --> 00:03:56,159
center the event encourages young people

96
00:04:01,509 --> 00:03:58,560
to develop and use skills in science

97
00:04:03,589 --> 00:04:01,519
technology engineering and math to build

98
00:04:04,789 --> 00:04:03,599
and race lightweight human-powered

99
00:04:06,789 --> 00:04:04,799
buggies

100
00:04:09,429 --> 00:04:06,799
nasa hopes these students will pursue

101
00:04:14,390 --> 00:04:09,439
careers in stem fields to benefit the

102
00:04:19,430 --> 00:04:16,469
nasa's hubble space telescope celebrated

103
00:04:22,390 --> 00:04:19,440
its 23rd anniversary by once again

104
00:04:24,310 --> 00:04:22,400
focusing on the iconic horsehead nebula

105
00:04:26,790 --> 00:04:24,320
but this time with the infrared eyes of

106
00:04:29,430 --> 00:04:26,800
its wide field camera 3.

107
00:04:31,749 --> 00:04:29,440
imaging the nebula in infrared revealed

108
00:04:32,710 --> 00:04:31,759
features previously hidden by gas and

109
00:04:35,030 --> 00:04:32,720
dust

110
00:04:37,110 --> 00:04:35,040
about 1500 light years away the

111
00:04:39,030 --> 00:04:37,120
horsehead lies in one of the closest and

112
00:04:41,670 --> 00:04:39,040
most commonly photographed regions of

113
00:04:43,749 --> 00:04:41,680
space where stars are actively forming

114
00:04:46,230 --> 00:04:43,759
the image is a preview of the infrared

115
00:04:48,710 --> 00:04:46,240
output expected from hubble's successor

116
00:04:54,310 --> 00:04:48,720
the james webb space telescope set to

117
00:04:59,670 --> 00:04:57,830
12 years ago on april 19 2001 space

118
00:05:02,390 --> 00:04:59,680
shuttle endeavour launched from kennedy

119
00:05:04,469 --> 00:05:02,400
space center on sts-100

120
00:05:06,550 --> 00:05:04,479
to deliver canon arm 2 to the

121
00:05:08,870 --> 00:05:06,560
international space station

122
00:05:11,270 --> 00:05:08,880
used to lift and move hardware and space

123
00:05:14,230 --> 00:05:11,280
spacewalking astronauts the canadian

124
00:05:16,150 --> 00:05:14,240
built robotic arm a longer more capable

125
00:05:17,909 --> 00:05:16,160
version of the shuttle's robot

126
00:05:20,390 --> 00:05:17,919
played a critical role in completing

127
00:05:22,550 --> 00:05:20,400
assembly of the space station

128
00:05:27,510 --> 00:05:22,560
also delivered supplies to the station

129
00:05:31,590 --> 00:05:29,830
and that's this week at nasa for more on
