1
00:00:04,640 --> 00:00:03,889
when you put a human being in a

2
00:00:07,629 --> 00:00:04,650
spacesuit

3
00:00:11,900 --> 00:00:07,639
suddenly the impossible is possible

4
00:00:14,450 --> 00:00:11,910
since 1965 nASA has conducted hundreds

5
00:00:18,590 --> 00:00:14,460
of EPA's short for extra vehicular

6
00:00:22,279 --> 00:00:18,600
activity so when I think of EBA I think

7
00:00:24,859 --> 00:00:22,289
of the symbolism of a fellow human being

8
00:00:27,950 --> 00:00:24,869
existing for even just a short period of

9
00:00:30,349 --> 00:00:27,960
time alone and separated from nearly

10
00:00:32,229 --> 00:00:30,359
everything else and I think of that

11
00:00:34,850 --> 00:00:32,239
symbol of that single person

12
00:00:37,900 --> 00:00:34,860
representing our species and

13
00:00:41,690 --> 00:00:37,910
representing our voyage of exploration

14
00:00:43,700 --> 00:00:41,700
before exploration can take place before

15
00:00:46,130 --> 00:00:43,710
a human being can step outside the

16
00:00:48,830 --> 00:00:46,140
spacecraft another mission must be

17
00:00:56,500 --> 00:00:48,840
accomplished the creation of the

18
00:01:01,939 --> 00:00:59,720
throughout the history of evey a NASA

19
00:01:04,850 --> 00:01:01,949
has sought to build the best spacesuit

20
00:01:07,670 --> 00:01:04,860
and tools to match the job required for

21
00:01:10,820 --> 00:01:07,680
the mission for our suit engineers this

22
00:01:14,029 --> 00:01:10,830
means designing testing and redesigning

23
00:01:15,649 --> 00:01:14,039
to get it right during Gemini our

24
00:01:18,260 --> 00:01:15,659
designers were faced with a tough

25
00:01:20,539 --> 00:01:18,270
challenge to create the very first u.s.

26
00:01:22,460 --> 00:01:20,549
space suits suits that would allow

27
00:01:25,149 --> 00:01:22,470
astronauts to work outside the

28
00:01:27,950 --> 00:01:25,159
spacecraft in low-earth orbit

29
00:01:30,050 --> 00:01:27,960
building on that experience new suits

30
00:01:32,930 --> 00:01:30,060
were developed for the Apollo missions

31
00:01:35,210 --> 00:01:32,940
this time astronauts needed to walk on

32
00:01:38,240 --> 00:01:35,220
the moon while carrying their own life

33
00:01:41,029 --> 00:01:38,250
support on their backs with planetary

34
00:01:43,730 --> 00:01:41,039
surface exploration is the objective the

35
00:01:48,380 --> 00:01:43,740
suit had to bend and move to facilitate

36
00:01:51,109 --> 00:01:48,390
tool use and protect the human during

37
00:01:53,380 --> 00:01:51,119
the shuttle years NASA redefined what

38
00:01:56,539 --> 00:01:53,390
could be done with EDA suits and tools

39
00:01:57,680 --> 00:01:56,549
retrieving broken satellites rescuing

40
00:02:00,650 --> 00:01:57,690
and rebuilding the Hubble Space

41
00:02:02,900 --> 00:02:00,660
Telescope and building the International

42
00:02:06,320 --> 00:02:02,910
Space Station the same shuttle spacesuit

43
00:02:08,809 --> 00:02:06,330
is on the space station today it allows

44
00:02:11,690 --> 00:02:08,819
us to maintain and repair our home in

45
00:02:15,320 --> 00:02:11,700
space but what about future missions

46
00:02:17,199 --> 00:02:15,330
what kind of a suit will we need will we

47
00:02:20,270 --> 00:02:17,209
be walking on a planetary surface

48
00:02:23,000 --> 00:02:20,280
floating in microgravity

49
00:02:24,920 --> 00:02:23,010
both NASA is already investigating the

50
00:02:27,440 --> 00:02:24,930
next generation of spacesuits

51
00:02:29,000 --> 00:02:27,450
creating a variety of prototypes to

52
00:02:35,450 --> 00:02:29,010
prepare astronauts for the journeys

53
00:02:37,820 --> 00:02:35,460
ahead the z2 is one of those prototypes

54
00:02:40,190 --> 00:02:37,830
it's sleek design looks different from

55
00:02:42,560 --> 00:02:40,200
any other spacesuit NASA previously

56
00:02:45,410 --> 00:02:42,570
built we were able to take some artistic

57
00:02:47,990 --> 00:02:45,420
license on this prototype spacesuit and

58
00:02:50,390 --> 00:02:48,000
have some fun with it and engage folks

59
00:02:52,370 --> 00:02:50,400
out around the country for what they

60
00:02:54,140 --> 00:02:52,380
would like to see in a spacesuit we work

61
00:02:56,870 --> 00:02:54,150
with Philadelphia University to do the

62
00:02:59,120 --> 00:02:56,880
initial layouts of the suit and then we

63
00:03:02,330 --> 00:02:59,130
have some in-house fashion designers

64
00:03:04,100 --> 00:03:02,340
that also help build our spacesuits and

65
00:03:07,400 --> 00:03:04,110
they were able to bring their

66
00:03:09,470 --> 00:03:07,410
experiences to it and evolve that cover

67
00:03:12,350 --> 00:03:09,480
layer to make it even better than what

68
00:03:15,290 --> 00:03:12,360
we started with the z2 isn't just

69
00:03:17,560 --> 00:03:15,300
fashion-forward on the outside it's also

70
00:03:20,660 --> 00:03:17,570
technologically advanced on the inside

71
00:03:23,000 --> 00:03:20,670
this is one suit made for walking on

72
00:03:24,470 --> 00:03:23,010
other planets that is to be a planetary

73
00:03:25,970 --> 00:03:24,480
spacesuit some of the special features

74
00:03:27,440 --> 00:03:25,980
on the z2 are boots

75
00:03:28,910 --> 00:03:27,450
specifically designed for walking and

76
00:03:31,610 --> 00:03:28,920
for keeping your foot integrated into

77
00:03:33,770 --> 00:03:31,620
the boot well like a good hiking boot it

78
00:03:36,229 --> 00:03:33,780
also has a lot of lower torso mobility

79
00:03:38,060 --> 00:03:36,239
that allows you to walk naturally so

80
00:03:40,220 --> 00:03:38,070
that you can go uphill downhill into

81
00:03:43,190 --> 00:03:40,230
craters pick up a rock as a geologist

82
00:03:45,740 --> 00:03:43,200
want to do on a planetary surface like

83
00:03:48,289 --> 00:03:45,750
any prototype NASA hopes to learn a lot

84
00:03:51,620 --> 00:03:48,299
from the z2 as it continues to improve

85
00:03:53,150 --> 00:03:51,630
and develop spacesuits prototypes are

86
00:03:54,680 --> 00:03:53,160
really important for spacesuit

87
00:03:56,900 --> 00:03:54,690
development because you can only do so

88
00:03:59,600 --> 00:03:56,910
much in the modeling and analysis world

89
00:04:01,460 --> 00:03:59,610
you really don't know how well the suit

90
00:04:03,229 --> 00:04:01,470
works until you integrated with a person

91
00:04:05,330 --> 00:04:03,239
you get the feedback that person can

92
00:04:07,069 --> 00:04:05,340
give you you have them walk around you

93
00:04:08,860 --> 00:04:07,079
have them try different tests that's how

94
00:04:12,580 --> 00:04:08,870
we really know that we've done a good

95
00:04:14,949 --> 00:04:12,590
design a spaceship another suit in the

96
00:04:19,090 --> 00:04:14,959
works is the prototype exploration suit

97
00:04:21,729 --> 00:04:19,100
or pxs this suit could be used for EVs

98
00:04:25,120 --> 00:04:21,739
in microgravity or it could be further

99
00:04:27,909 --> 00:04:25,130
modified for walking on planets as with

100
00:04:30,969 --> 00:04:27,919
all future spacesuits NASA is wanting to

101
00:04:34,540 --> 00:04:30,979
see better mobility more visibility and

102
00:04:36,189 --> 00:04:34,550
better control and communication so one

103
00:04:38,260 --> 00:04:36,199
of my main responsibilities on the space

104
00:04:39,790 --> 00:04:38,270
suit is the suit control assembly and

105
00:04:41,379 --> 00:04:39,800
that's the box that sits right here on

106
00:04:43,540 --> 00:04:41,389
the front of the suit and it allows the

107
00:04:45,520 --> 00:04:43,550
crew member to control their life

108
00:04:47,260 --> 00:04:45,530
support components such as their cooling

109
00:04:49,420 --> 00:04:47,270
and their pressure and it also controls

110
00:04:52,000 --> 00:04:49,430
a lot of the electronics such as the

111
00:04:53,469 --> 00:04:52,010
radio and the volume and they can see

112
00:04:54,879 --> 00:04:53,479
some of the data that's coming back and

113
00:04:57,370 --> 00:04:54,889
forth from the suit computer to that

114
00:05:00,070 --> 00:04:57,380
display so one of the great things about

115
00:05:02,500 --> 00:05:00,080
this job is that after designing the Box

116
00:05:04,270 --> 00:05:02,510
I'm able to get into the suit since it's

117
00:05:07,230 --> 00:05:04,280
one of the smaller sizes and we can

118
00:05:10,750 --> 00:05:07,240
actually see what the limitations are

119
00:05:12,730 --> 00:05:10,760
you know with my own hands and eyes and

120
00:05:14,290 --> 00:05:12,740
not just hear that secondhand from

121
00:05:16,089 --> 00:05:14,300
another test subject that would be

122
00:05:17,620 --> 00:05:16,099
looking at the same data and then to

123
00:05:19,839 --> 00:05:17,630
take that back and then to go build the

124
00:05:21,580 --> 00:05:19,849
next prototype and you know incorporate

125
00:05:26,440 --> 00:05:21,590
the changes that need to be made so that

126
00:05:30,879 --> 00:05:26,450
it works better the next time whether

127
00:05:33,969 --> 00:05:30,889
it's the pxs or the z2 new NASA space

128
00:05:35,860 --> 00:05:33,979
suits have a big job to do and if not

129
00:05:39,010 --> 00:05:35,870
just being in a vacuum but it's very hot

130
00:05:40,060 --> 00:05:39,020
it can be very cold and then in addition

131
00:05:42,370 --> 00:05:40,070
to that there are a little micro

132
00:05:43,980 --> 00:05:42,380
meteoroids that are flying past that you

133
00:05:45,900 --> 00:05:43,990
have to protect in case it does

134
00:05:48,029 --> 00:05:45,910
the suit so so there's a lot of things

135
00:05:50,189 --> 00:05:48,039
to go into protecting the crew member in

136
00:05:52,529 --> 00:05:50,199
addition to just being in a vacuum and

137
00:05:54,390 --> 00:05:52,539
when we go farther to the Moon or Mars

138
00:05:56,189 --> 00:05:54,400
you have to protect encase you trip and

139
00:05:59,879 --> 00:05:56,199
fall so there's a lot of protection that

140
00:06:03,240 --> 00:05:59,889
the suit has to take into account no

141
00:06:06,059 --> 00:06:03,250
matter where we go or what we do space

142
00:06:09,659 --> 00:06:06,069
suits and EDA tasks will continue to

143
00:06:12,330 --> 00:06:09,669
change and evolve to keep up space suit

144
00:06:15,240 --> 00:06:12,340
engineers will use new technologies new

145
00:06:17,189 --> 00:06:15,250
materials and new ideas to help us on

146
00:06:20,400 --> 00:06:17,199
our way in the future I'm looking

147
00:06:23,310 --> 00:06:20,410
forward to spacesuits that are much more

148
00:06:25,439 --> 00:06:23,320
of a tool flash not that is more

149
00:06:27,629 --> 00:06:25,449
integrated with the human and is less of

150
00:06:31,189 --> 00:06:27,639
a encumbrance and more of a help

151
00:06:33,779 --> 00:06:31,199
I think of EBA as basically a ship of

152
00:06:36,469 --> 00:06:33,789
exploration a ship of learning and

153
00:06:39,060 --> 00:06:36,479
understanding both about what makes us

154
00:06:43,290 --> 00:06:39,070
individually human and about what makes

155
00:06:46,020 --> 00:06:43,300
us together a team that seeks to learn

156
00:06:48,540 --> 00:06:46,030
and understand what the truth around us

157
00:06:51,490 --> 00:06:48,550
is and that search for knowledge that

158
00:06:54,400 --> 00:06:51,500
search for truth is I think one of the
