1
00:00:06,470 --> 00:00:03,669
the new members of the international

2
00:00:08,470 --> 00:00:06,480
space station's expedition 40 crew share

3
00:00:10,870 --> 00:00:08,480
an affinity for exploration on this

4
00:00:13,030 --> 00:00:10,880
planet but they're also eager to take up

5
00:00:16,710 --> 00:00:13,040
the challenge of setting the stage for

6
00:00:18,870 --> 00:00:16,720
future exploration off the planet max

7
00:00:21,429 --> 00:00:18,880
arrive is the son of a soviet air force

8
00:00:23,429 --> 00:00:21,439
officer he was born in chelyabinsk in

9
00:00:25,830 --> 00:00:23,439
the southern ural region of russia north

10
00:00:28,150 --> 00:00:25,840
of kazakhstan but his family moved all

11
00:00:30,070 --> 00:00:28,160
over the country during his childhood

12
00:00:32,709 --> 00:00:30,080
all along he intended to become a

13
00:00:35,190 --> 00:00:32,719
military pilot the idea of becoming a

14
00:00:36,310 --> 00:00:35,200
cosmonaut was just an extension of that

15
00:00:39,510 --> 00:00:36,320
idea

16
00:00:41,830 --> 00:00:39,520
and i thought i'd give it a shot because

17
00:00:44,630 --> 00:00:41,840
the profession of a military pilot is

18
00:00:46,389 --> 00:00:44,640
very similar to that of a cosmonaut

19
00:00:49,350 --> 00:00:46,399
making quick decisions making right

20
00:00:51,510 --> 00:00:49,360
decisions so something risky something

21
00:00:54,150 --> 00:00:51,520
complicated something challenging

22
00:00:56,630 --> 00:00:54,160
something interesting which brings a lot

23
00:00:58,790 --> 00:00:56,640
of pleasure if you manage

24
00:01:01,270 --> 00:00:58,800
after high school in noginsk near star

25
00:01:03,270 --> 00:01:01,280
city sarayev graduated from the kasha

26
00:01:05,509 --> 00:01:03,280
air force pilot school in the crimea

27
00:01:07,109 --> 00:01:05,519
with a specialty in command tactical

28
00:01:08,950 --> 00:01:07,119
fighter aviation

29
00:01:11,190 --> 00:01:08,960
then he went to the zhukovsky air force

30
00:01:13,270 --> 00:01:11,200
academy to specialize in test and

31
00:01:15,510 --> 00:01:13,280
exploitation of aircraft and weapons

32
00:01:17,510 --> 00:01:15,520
systems he applied to the cosmonaut

33
00:01:19,670 --> 00:01:17,520
corps and was selected the year before

34
00:01:22,070 --> 00:01:19,680
he finished at the academy and while

35
00:01:24,149 --> 00:01:22,080
training in star city he also graduated

36
00:01:25,429 --> 00:01:24,159
from the civil service academy of russia

37
00:01:27,429 --> 00:01:25,439
as a lawyer

38
00:01:31,109 --> 00:01:27,439
sarah's first flight was a six-month

39
00:01:33,990 --> 00:01:31,119
tour on expeditions 21 and 22 in 2009

40
00:01:35,190 --> 00:01:34,000
and 2010 during which he completed one

41
00:01:36,950 --> 00:01:35,200
spacewalk

42
00:01:40,230 --> 00:01:36,960
although he retired from the russian air

43
00:01:42,149 --> 00:01:40,240
force as a colonel in 2012 he continues

44
00:01:44,710 --> 00:01:42,159
to work for the cause of human space

45
00:01:47,429 --> 00:01:44,720
exploration

46
00:01:49,590 --> 00:01:47,439
that's why we send humans in space

47
00:01:52,870 --> 00:01:49,600
so that we move forward we may discover

48
00:01:54,630 --> 00:01:52,880
something in the future maybe

49
00:01:57,510 --> 00:01:54,640
maybe not in

50
00:02:00,950 --> 00:01:57,520
so near future but discovering some new

51
00:02:04,230 --> 00:02:02,709
something that will help us develop and

52
00:02:06,950 --> 00:02:04,240
move forward

53
00:02:09,510 --> 00:02:06,960
us navy commander reed wiseman grew up

54
00:02:11,350 --> 00:02:09,520
in the suburbs of baltimore maryland far

55
00:02:13,990 --> 00:02:11,360
enough away from the city to be able to

56
00:02:15,510 --> 00:02:14,000
enjoy nature learn about the world and

57
00:02:17,990 --> 00:02:15,520
make the most of the freedom and

58
00:02:20,309 --> 00:02:18,000
encouragement he got from his parents

59
00:02:22,150 --> 00:02:20,319
and they always had boundaries but

60
00:02:23,510 --> 00:02:22,160
it was exploration from the time i was

61
00:02:24,550 --> 00:02:23,520
born you know going to the lake with my

62
00:02:26,390 --> 00:02:24,560
brother

63
00:02:28,710 --> 00:02:26,400
learning on my own and figuring things

64
00:02:31,030 --> 00:02:28,720
out and and they gave me that that

65
00:02:32,949 --> 00:02:31,040
freedom and it was wonderful

66
00:02:35,350 --> 00:02:32,959
wiseman earned a bachelor's of science

67
00:02:36,790 --> 00:02:35,360
in computer and systems engineering and

68
00:02:40,470 --> 00:02:36,800
a commission in the navy through the

69
00:02:42,309 --> 00:02:40,480
rotc at rensselaer polytechnic institute

70
00:02:44,470 --> 00:02:42,319
after flight training he was assigned to

71
00:02:46,150 --> 00:02:44,480
an f-14 squadron and made two

72
00:02:48,229 --> 00:02:46,160
deployments to the middle east during

73
00:02:50,710 --> 00:02:48,239
operations southern watch enduring

74
00:02:52,390 --> 00:02:50,720
freedom and iraqi freedom during the

75
00:02:54,869 --> 00:02:52,400
second deployment he was picked for the

76
00:02:56,710 --> 00:02:54,879
navy's test pilot school and later while

77
00:02:58,949 --> 00:02:56,720
working at the patuxent river naval air

78
00:03:00,630 --> 00:02:58,959
station he also earned a master's degree

79
00:03:02,869 --> 00:03:00,640
in systems engineering from johns

80
00:03:04,790 --> 00:03:02,879
hopkins wiseman made two more

81
00:03:07,670 --> 00:03:04,800
international deployments before he was

82
00:03:09,270 --> 00:03:07,680
picked for the astronaut program in 2009

83
00:03:12,229 --> 00:03:09,280
and got the chance to resume the

84
00:03:14,550 --> 00:03:12,239
exploration he loved as a child

85
00:03:17,030 --> 00:03:14,560
we are curious we are inquisitive we are

86
00:03:19,670 --> 00:03:17,040
explorers by our very nature and right

87
00:03:23,030 --> 00:03:19,680
now the biggest exploration that a human

88
00:03:25,190 --> 00:03:23,040
can go on is 250 miles up on the space

89
00:03:27,430 --> 00:03:25,200
station so to me there's not even a

90
00:03:29,990 --> 00:03:27,440
question of course it's worth the risk

91
00:03:30,869 --> 00:03:30,000
just to go out there and push humanity

92
00:03:32,869 --> 00:03:30,879
to

93
00:03:35,430 --> 00:03:32,879
further than we've been

94
00:03:38,550 --> 00:03:35,440
that's that's a no-brainer

95
00:03:40,710 --> 00:03:38,560
dr alexander gerst was born in kunzelsau

96
00:03:43,030 --> 00:03:40,720
a small town in rural south central

97
00:03:45,350 --> 00:03:43,040
germany he liked being close to nature

98
00:03:47,030 --> 00:03:45,360
and looking up at the night sky and his

99
00:03:48,949 --> 00:03:47,040
curiosity was piqued when his

100
00:03:51,830 --> 00:03:48,959
grandfather talked to people all over

101
00:03:55,270 --> 00:03:51,840
the world on his amateur radio one day

102
00:03:56,949 --> 00:03:55,280
he somehow managed to adjust his antenna

103
00:03:58,229 --> 00:03:56,959
such that it would actually broadcast to

104
00:03:59,190 --> 00:03:58,239
the moon

105
00:04:02,470 --> 00:03:59,200
and

106
00:04:05,429 --> 00:04:02,480
speak

107
00:04:07,190 --> 00:04:05,439
a few words into the radio they would

108
00:04:09,270 --> 00:04:07,200
bounce back from the surface of the moon

109
00:04:12,550 --> 00:04:09,280
and about two and a half seconds later i

110
00:04:14,869 --> 00:04:12,560
would hear my own words in the radio

111
00:04:17,830 --> 00:04:14,879
knowing as a six-year-old that they were

112
00:04:20,469 --> 00:04:17,840
just on the moon so it was impossible

113
00:04:22,790 --> 00:04:20,479
for me to grasp in the beginning

114
00:04:25,110 --> 00:04:22,800
gerst started his exploration focused on

115
00:04:26,950 --> 00:04:25,120
this planet and earned a diploma in

116
00:04:29,510 --> 00:04:26,960
geophysics from the university of

117
00:04:31,749 --> 00:04:29,520
karlsruhe in germany while also getting

118
00:04:34,230 --> 00:04:31,759
his masters in earth sciences from

119
00:04:36,390 --> 00:04:34,240
victoria university in new zealand while

120
00:04:38,790 --> 00:04:36,400
working there developing new volcano

121
00:04:40,950 --> 00:04:38,800
monitoring techniques he made four

122
00:04:43,030 --> 00:04:40,960
scientific missions to study volcanoes

123
00:04:45,350 --> 00:04:43,040
in antarctica while working on his

124
00:04:47,030 --> 00:04:45,360
doctorate in natural sciences at the

125
00:04:49,270 --> 00:04:47,040
institute of geophysics at the

126
00:04:51,350 --> 00:04:49,280
university of hamburg and during that

127
00:04:53,670 --> 00:04:51,360
time he made good on a promise to

128
00:04:56,469 --> 00:04:53,680
himself that he would make at least one

129
00:04:58,310 --> 00:04:56,479
sincere effort to become an astronaut he

130
00:05:01,430 --> 00:04:58,320
was selected for the astronaut corps by

131
00:05:03,990 --> 00:05:01,440
the european space agency in 2009

132
00:05:06,150 --> 00:05:04,000
finished his phd the following year and

133
00:05:08,310 --> 00:05:06,160
has been focused ever since on his

134
00:05:09,590 --> 00:05:08,320
chance to be part of what he calls the

135
00:05:10,469 --> 00:05:09,600
first wave

136
00:05:13,189 --> 00:05:10,479
being

137
00:05:15,909 --> 00:05:13,199
the first well wave of explorers on the

138
00:05:19,590 --> 00:05:15,919
way out exploring the universe

139
00:05:20,629 --> 00:05:19,600
to moon asteroids mars and beyond

140
00:05:23,670 --> 00:05:20,639
that is

141
00:05:24,710 --> 00:05:23,680
for me such an important thing to do for

142
00:05:25,990 --> 00:05:24,720
for
