[Music]

2
00:00:11,509 --> 00:00:09,190
so wow that was uh

3
00:00:13,749 --> 00:00:11,519
a huge experience in my life we worked

4
00:00:15,350 --> 00:00:13,759
for many years to get ready for that and

5
00:00:16,870 --> 00:00:15,360
then we were sitting in the crew lock

6
00:00:18,550 --> 00:00:16,880
which is this part of the airlock that

7
00:00:21,590 --> 00:00:18,560
goes to vacuum we were supposed to

8
00:00:24,070 --> 00:00:21,600
depressurize in 30 minutes that was the

9
00:00:25,750 --> 00:00:24,080
that was the theoretical thing but they

10
00:00:27,349 --> 00:00:25,760
missed the calculation somewhat and it

11
00:00:29,189 --> 00:00:27,359
took over an hour

12
00:00:31,429 --> 00:00:29,199
so i'm you know we're kind of anxious

13
00:00:33,110 --> 00:00:31,439
and then the capcom dan burbank

14
00:00:33,990 --> 00:00:33,120
whispered in my ear

15
00:00:36,389 --> 00:00:34,000
this

16
00:00:38,470 --> 00:00:36,399
is the anniversary of the first moonwalk

17
00:00:40,709 --> 00:00:38,480
and i did not know that and we weren't

18
00:00:42,790 --> 00:00:40,719
expecting to go out the door

19
00:00:44,069 --> 00:00:42,800
on that date and so anyway all those

20
00:00:46,950 --> 00:00:44,079
thoughts were running through my mind

21
00:00:49,029 --> 00:00:46,960
and and then as i went out the door it's

22
00:00:50,549 --> 00:00:49,039
very different than the shuttle i had

23
00:00:52,310 --> 00:00:50,559
done spacewalks from the shuttle and you

24
00:00:54,630 --> 00:00:52,320
have the payload bay underneath you you

25
00:00:57,270 --> 00:00:54,640
feel like you have a floor under you and

26
00:01:00,150 --> 00:00:57,280
we came out or i came out first

27
00:01:02,150 --> 00:01:00,160
and the hatch of the iss airlock points

28
00:01:03,670 --> 00:01:02,160
nader which means toward earth so as you

29
00:01:06,789 --> 00:01:03,680
look at the hatch you feel like you're

30
00:01:09,030 --> 00:01:06,799
falling from 250 miles and so that was a

31
00:01:11,590 --> 00:01:09,040
big rush everything we do at nasa is a

32
00:01:13,670 --> 00:01:11,600
great team effort and and i worked with

33
00:01:15,270 --> 00:01:13,680
the one of the greatest teams at nasa to

34
00:01:17,190 --> 00:01:15,280
develop this airlock and appropriate

35
00:01:19,510 --> 00:01:17,200
protocol and when i went out the door i

36
00:01:21,590 --> 00:01:19,520
had all their names on my cuff checklist

37
00:01:23,350 --> 00:01:21,600
and i really uh

38
00:01:25,270 --> 00:01:23,360
really showed in my appreciation for all

39
00:01:26,390 --> 00:01:25,280
the teamwork that it took and

40
00:01:28,390 --> 00:01:26,400
and

41
00:01:30,710 --> 00:01:28,400
it was really quite an amazing

42
00:01:32,630 --> 00:01:30,720
effort and when you look at it

43
00:01:34,469 --> 00:01:32,640
you know the space station was assembled

44
00:01:36,069 --> 00:01:34,479
from spacewalks it's maintained from

45
00:01:37,429 --> 00:01:36,079
spacewalks we've had to change out

46
00:01:38,469 --> 00:01:37,439
batteries and do all kinds of

47
00:01:40,230 --> 00:01:38,479
maintenance

48
00:01:41,830 --> 00:01:40,240
if you can't get out the door

49
00:01:44,149 --> 00:01:41,840
efficiently then you can't do all these

50
00:01:46,630 --> 00:01:44,159
space walks and so the implementation of

51
00:01:48,630 --> 00:01:46,640
the airlock with the pre-brief protocol

52
00:01:50,469 --> 00:01:48,640
that that was basically

53
00:01:52,550 --> 00:01:50,479
like two and a half hours which was

54
00:01:54,870 --> 00:01:52,560
actually very low compared to what we

55
00:01:57,109 --> 00:01:54,880
thought we'd have to do and then all the

56
00:01:59,510 --> 00:01:57,119
little tools that we developed for that

57
00:02:01,510 --> 00:01:59,520
mission things like the crew lock bags

58
00:02:02,469 --> 00:02:01,520
that you carry your tools in i worked

59
00:02:04,630 --> 00:02:02,479
with the

60
00:02:06,069 --> 00:02:04,640
the crew and thermal systems guys to

61
00:02:08,229 --> 00:02:06,079
design those

62
00:02:09,910 --> 00:02:08,239
and then we um i had actually invented

63
00:02:12,550 --> 00:02:09,920
this device called the body restraint

64
00:02:15,110 --> 00:02:12,560
tether that comes off your waist and you

65
00:02:15,830 --> 00:02:15,120
use that to hold on to a handhold and

66
00:02:19,910 --> 00:02:15,840
for

67
00:02:20,949 --> 00:02:19,920
that's enough to restrain yourself and

68
00:02:22,790 --> 00:02:20,959
so

69
00:02:25,110 --> 00:02:22,800
and we honestly probably couldn't have

70
00:02:27,510 --> 00:02:25,120
built station as well as we did without

71
00:02:29,830 --> 00:02:27,520
that feels great so all those techniques

72
00:02:31,910 --> 00:02:29,840
that that we really develop to do

73
00:02:34,070 --> 00:02:31,920
space walks from the space station have

74
00:02:36,150 --> 00:02:34,080
been used again and again and again to

75
00:02:38,470 --> 00:02:36,160
great success so the space walks on the

76
00:02:40,390 --> 00:02:38,480
moon will be very different than on iss

77
00:02:42,309 --> 00:02:40,400
so in iss we're doing some detailed

78
00:02:44,470 --> 00:02:42,319
maintenance changing out battery packs

79
00:02:45,670 --> 00:02:44,480
and things of this nature whereas on the

80
00:02:47,830 --> 00:02:45,680
moon

81
00:02:49,670 --> 00:02:47,840
we're there to explore and to take

82
00:02:51,910 --> 00:02:49,680
advantage of the human brain and

83
00:02:54,229 --> 00:02:51,920
judgment and their hands to do

84
00:02:55,670 --> 00:02:54,239
exploration so so the task will involve

85
00:02:58,149 --> 00:02:55,680
science we'll still have some

86
00:03:01,030 --> 00:02:58,159
maintenance to do on the rover there'll

87
00:03:02,710 --> 00:03:01,040
still be some of that but your daily

88
00:03:10,070 --> 00:03:02,720
spacewalks will be focused on the

89
00:03:18,869 --> 00:03:12,670
