1
00:00:04,630 --> 00:00:02,790
why do we explore

2
00:00:06,550 --> 00:00:04,640
you know i think venturing out into low

3
00:00:08,629 --> 00:00:06,560
earth orbit and beyond

4
00:00:11,110 --> 00:00:08,639
helps us to better understand

5
00:00:13,749 --> 00:00:11,120
who we are and our place in the solar

6
00:00:15,430 --> 00:00:13,759
system and the universe

7
00:00:17,590 --> 00:00:15,440
my name is chell lindgren and i'm the

8
00:00:18,950 --> 00:00:17,600
commander for nasa's spacex crew 4

9
00:00:20,630 --> 00:00:18,960
mission to the international space

10
00:00:22,630 --> 00:00:20,640
station

11
00:00:25,029 --> 00:00:22,640
i grew up in an air force family and so

12
00:00:26,790 --> 00:00:25,039
i was born in taiwan and spent the first

13
00:00:29,189 --> 00:00:26,800
two years of my life there

14
00:00:31,269 --> 00:00:29,199
we lived in kansas and illinois

15
00:00:33,030 --> 00:00:31,279
and then we were transferred to england

16
00:00:34,950 --> 00:00:33,040
it was a phenomenal

17
00:00:37,110 --> 00:00:34,960
upbringing the opportunity to experience

18
00:00:40,389 --> 00:00:37,120
different cultures it really opened my

19
00:00:42,150 --> 00:00:40,399
eyes to what it means to be an american

20
00:00:44,790 --> 00:00:42,160
i wanted to be an astronaut for as long

21
00:00:46,950 --> 00:00:44,800
as i can remember i think i was inspired

22
00:00:52,549 --> 00:00:46,960
by the very first space shuttle launch

23
00:00:57,430 --> 00:00:54,869
america's first space shuttle

24
00:00:59,830 --> 00:00:57,440
and the shuttle has cleared the tower

25
00:01:02,549 --> 00:00:59,840
and that i think is really when this

26
00:01:03,910 --> 00:01:02,559
this dream was was uh just burned into

27
00:01:05,030 --> 00:01:03,920
my consciousness

28
00:01:07,030 --> 00:01:05,040
and so

29
00:01:09,030 --> 00:01:07,040
i charted out a path i went to the air

30
00:01:11,750 --> 00:01:09,040
force academy maybe to become a test

31
00:01:13,350 --> 00:01:11,760
pilot and then ultimately to join nasa

32
00:01:15,429 --> 00:01:13,360
as an astronaut

33
00:01:17,429 --> 00:01:15,439
that path took some twists and curves

34
00:01:19,429 --> 00:01:17,439
and i ultimately did not become a pilot

35
00:01:21,749 --> 00:01:19,439
but went into medicine

36
00:01:24,149 --> 00:01:21,759
and yet still found a path through

37
00:01:25,910 --> 00:01:24,159
medicine where i could serve human space

38
00:01:28,550 --> 00:01:25,920
flight as a flight surgeon

39
00:01:31,030 --> 00:01:28,560
at nasa supporting our crews training

40
00:01:32,950 --> 00:01:31,040
for international space station missions

41
00:01:35,670 --> 00:01:32,960
but i still had that dream that that

42
00:01:36,870 --> 00:01:35,680
perhaps i would get to do that job

43
00:01:39,590 --> 00:01:36,880
someday

44
00:01:41,749 --> 00:01:39,600
it was absolutely amazing to get the

45
00:01:43,429 --> 00:01:41,759
call that i had been selected into the

46
00:01:44,789 --> 00:01:43,439
astronaut office

47
00:01:47,749 --> 00:01:44,799
and it felt

48
00:01:50,710 --> 00:01:47,759
a little bit like a culmination of

49
00:01:52,630 --> 00:01:50,720
the hard work that i had invested in

50
00:01:54,630 --> 00:01:52,640
getting to that point

51
00:01:56,630 --> 00:01:54,640
what an amazing really dream come true

52
00:01:59,510 --> 00:01:56,640
for me

53
00:02:01,910 --> 00:01:59,520
in 2013 i was assigned to my first

54
00:02:03,190 --> 00:02:01,920
mission and spent 141 days living and

55
00:02:04,709 --> 00:02:03,200
working on the international space

56
00:02:06,310 --> 00:02:04,719
station

57
00:02:08,949 --> 00:02:06,320
that truly was

58
00:02:11,270 --> 00:02:08,959
the realization of that lifelong dream

59
00:02:12,470 --> 00:02:11,280
of all those things in that moment and

60
00:02:16,229 --> 00:02:12,480
in that mission

61
00:02:21,510 --> 00:02:19,110
it was an absolute honor to get selected

62
00:02:24,229 --> 00:02:21,520
for the crew four mission and on top of

63
00:02:26,390 --> 00:02:24,239
that to have the opportunity to command

64
00:02:27,190 --> 00:02:26,400
getting to fly with this amazing crew

65
00:02:30,309 --> 00:02:27,200
with

66
00:02:32,710 --> 00:02:30,319
farmer and samantha and wadi they are

67
00:02:35,670 --> 00:02:32,720
incredible astronauts and i feel

68
00:02:38,150 --> 00:02:35,680
very grateful to be on a team with them

69
00:02:42,550 --> 00:02:38,160
but we're one small part of a larger

70
00:02:44,630 --> 00:02:42,560
team that spans the nation and the world

71
00:02:47,030 --> 00:02:44,640
we truly get to leverage the best and

72
00:02:49,750 --> 00:02:47,040
brightest as we chase somewhat

73
00:02:52,390 --> 00:02:49,760
impossible goals

74
00:02:53,910 --> 00:02:52,400
and so as we push forward to the moon as

75
00:02:55,350 --> 00:02:53,920
we push to mars we are presenting

76
00:02:57,589 --> 00:02:55,360
ourselves with

77
00:02:58,790 --> 00:02:57,599
almost insurmountable challenges by

78
00:03:00,949 --> 00:02:58,800
presenting ourselves with those

79
00:03:10,110 --> 00:03:00,959
challenges we become better as a
