1
00:00:02,710 --> 00:00:01,590
about that all right we're going to see

2
00:00:04,630 --> 00:00:02,720
how they're putting this technology to

3
00:00:06,309 --> 00:00:04,640
work thank you fred

4
00:00:07,829 --> 00:00:06,319
i'm here now with ken fernandez from the

5
00:00:10,310 --> 00:00:07,839
science and mission systems office and

6
00:00:12,150 --> 00:00:10,320
ken you've got a surface mobility

7
00:00:13,270 --> 00:00:12,160
operation here that

8
00:00:14,470 --> 00:00:13,280
looks like you're just playing with toy

9
00:00:16,310 --> 00:00:14,480
cars right

10
00:00:19,429 --> 00:00:16,320
what we're doing is we're working on

11
00:00:21,429 --> 00:00:19,439
technologies that will be needed to

12
00:00:22,950 --> 00:00:21,439
field the next generation of surface

13
00:00:25,189 --> 00:00:22,960
mobility systems

14
00:00:26,310 --> 00:00:25,199
these systems go beyond what we did in

15
00:00:28,790 --> 00:00:26,320
apollo

16
00:00:31,189 --> 00:00:28,800
which was a system the lunar rover was a

17
00:00:33,670 --> 00:00:31,199
system that just ferry net astronauts

18
00:00:35,750 --> 00:00:33,680
around the systems in the future will

19
00:00:37,750 --> 00:00:35,760
have to work with a higher degree of

20
00:00:39,350 --> 00:00:37,760
autonomy

21
00:00:44,310 --> 00:00:39,360
to do that

22
00:00:46,950 --> 00:00:44,320
because we have gps we have

23
00:00:48,869 --> 00:00:46,960
communication satellites but on on a

24
00:00:51,029 --> 00:00:48,879
place like the moon

25
00:00:53,270 --> 00:00:51,039
none of that is uh present

26
00:00:55,270 --> 00:00:53,280
so we're working on one technology here

27
00:00:57,670 --> 00:00:55,280
that we're actually going to demonstrate

28
00:01:00,229 --> 00:00:57,680
in the september october time frame near

29
00:01:02,549 --> 00:01:00,239
building 4614

30
00:01:04,710 --> 00:01:02,559
this is a system that provides both

31
00:01:08,230 --> 00:01:04,720
navigational information

32
00:01:09,030 --> 00:01:08,240
and communications for a rover okay

33
00:01:10,469 --> 00:01:09,040
and

34
00:01:13,350 --> 00:01:10,479
for any system it could work with a

35
00:01:14,070 --> 00:01:13,360
lander also but we deploy these around

36
00:01:17,109 --> 00:01:14,080
and

37
00:01:18,230 --> 00:01:17,119
the system works just like gps

38
00:01:20,469 --> 00:01:18,240
and

39
00:01:22,310 --> 00:01:20,479
it's far less costly than trying to

40
00:01:24,469 --> 00:01:22,320
implement that on the moon so you deploy

41
00:01:26,789 --> 00:01:24,479
those around and then you send these

42
00:01:29,030 --> 00:01:26,799
yeah this is a this is a system that

43
00:01:33,109 --> 00:01:29,040
we're adapting for nasa use it's

44
00:01:37,190 --> 00:01:33,119
originally a military robot that uh they

45
00:01:38,710 --> 00:01:37,200
use to examine ieds in in the in the war

46
00:01:41,270 --> 00:01:38,720
uh areas

47
00:01:44,149 --> 00:01:41,280
and uh we're going to develop computer

48
00:01:45,190 --> 00:01:44,159
control for this so that we can

49
00:01:47,109 --> 00:01:45,200
operate it

50
00:01:49,030 --> 00:01:47,119
autonomously and we're going to mount

51
00:01:50,870 --> 00:01:49,040
one of the navigation sensors that is

52
00:01:52,789 --> 00:01:50,880
associated with this and do the

53
00:01:55,030 --> 00:01:52,799
autonomous navigation

54
00:01:57,749 --> 00:01:55,040
other technologies that we're working on

55
00:01:59,510 --> 00:01:57,759
are you know various uh

56
00:02:01,190 --> 00:01:59,520
trailering uh

57
00:02:04,550 --> 00:02:01,200
operations one of the things you might

58
00:02:07,510 --> 00:02:04,560
want to do with a rover is to go out and

59
00:02:09,430 --> 00:02:07,520
find a payload a nuclear reactor hook up

60
00:02:11,990 --> 00:02:09,440
to it and move it to a safe location

61
00:02:14,150 --> 00:02:12,000
without expo exposing the crew

62
00:02:15,430 --> 00:02:14,160
so this is the mechanisms are an

63
00:02:16,710 --> 00:02:15,440
important part

64
00:02:19,589 --> 00:02:16,720
we're also

65
00:02:21,270 --> 00:02:19,599
working on various sensors this is a

66
00:02:23,910 --> 00:02:21,280
sick lidar

67
00:02:25,270 --> 00:02:23,920
we're also looking at flash lidars we're

68
00:02:29,750 --> 00:02:25,280
looking at

69
00:02:34,869 --> 00:02:32,470
algorithms for providing guidance and

70
00:02:37,509 --> 00:02:34,879
then the big daddy the big daddy is an

71
00:02:39,910 --> 00:02:37,519
irobot our gator and

72
00:02:42,790 --> 00:02:39,920
we're using a system that was developed

73
00:02:45,509 --> 00:02:42,800
for the military and because systems

74
00:02:49,190 --> 00:02:45,519
like this are available it saves us a

75
00:02:51,430 --> 00:02:49,200
lot of money in developing a test bed

76
00:02:54,150 --> 00:02:51,440
capability so this is a larger platform

77
00:02:57,350 --> 00:02:54,160
that allows us to put more sensors on

78
00:02:58,630 --> 00:02:57,360
and a lot a lot more capabilities

79
00:03:02,790 --> 00:02:58,640
the little

80
00:03:04,869 --> 00:03:02,800
but it's very limited but it provides us

81
00:03:05,910 --> 00:03:04,879
an initial first cut so this is really

82
00:03:07,830 --> 00:03:05,920
going to get us to the moon and see

83
00:03:09,430 --> 00:03:07,840
what's there before we get there well

84
00:03:12,070 --> 00:03:09,440
hopefully and it'll help us do a lot of

85
00:03:13,509 --> 00:03:12,080
things that we couldn't do otherwise all

86
00:03:14,949 --> 00:03:13,519
right thanks ken so much for showing us

87
00:03:15,910 --> 00:03:14,959
your technology thanks laurie for coming

88
00:03:17,509 --> 00:03:15,920
by

89
00:03:19,190 --> 00:03:17,519
we're here with jim richard who is the

90
00:03:20,869 --> 00:03:19,200
team lead of the valve actuators and

91
00:03:22,070 --> 00:03:20,879
ducks branch and jim before we get to

92
00:03:23,830 --> 00:03:22,080
some of the new technology you've been

93
00:03:25,270 --> 00:03:23,840
developing what is this large hunk of

94
00:03:27,670 --> 00:03:25,280
hardware you've got here

95
00:03:30,949 --> 00:03:27,680
this is the pre-valve locks pre-valve

96
00:03:32,390 --> 00:03:30,959
for the saturn s4b rocket we've borrowed

97
00:03:34,390 --> 00:03:32,400
this from the space and rocket center

98
00:03:36,309 --> 00:03:34,400
and are using it to evaluate new

99
00:03:38,070 --> 00:03:36,319
technologies against for this area's

100
00:03:40,149 --> 00:03:38,080
vehicle so you pulled this right out of

101
00:03:41,990 --> 00:03:40,159
the saturn rocket that is correct how

102
00:03:43,430 --> 00:03:42,000
much does that weigh this valve weighs

103
00:03:44,949 --> 00:03:43,440
about 40 pounds that's currently

104
00:03:46,869 --> 00:03:44,959
configured well we'll let you set that

105
00:03:48,149 --> 00:03:46,879
down then because it's pretty heavy and

106
00:03:49,509 --> 00:03:48,159
you can uh show us some of the new

107
00:03:52,149 --> 00:03:49,519
technology you're working on here sure

108
00:03:53,990 --> 00:03:52,159
um the upper part of this valve is a

109
00:03:56,229 --> 00:03:54,000
pneumatic actuator with a large spring

110
00:03:57,990 --> 00:03:56,239
return system in it and this part of the

111
00:03:59,270 --> 00:03:58,000
valve contributes about half the weight

112
00:04:01,589 --> 00:03:59,280
of the valve

113
00:04:02,390 --> 00:04:01,599
the new technologies we're working on

114
00:04:04,710 --> 00:04:02,400
are

115
00:04:07,030 --> 00:04:04,720
paysio systems such as these

116
00:04:07,990 --> 00:04:07,040
this payzeo system weighs about four

117
00:04:09,830 --> 00:04:08,000
pounds

118
00:04:11,830 --> 00:04:09,840
and we can substantially reduce the

119
00:04:13,910 --> 00:04:11,840
weight of this valve and increase its

120
00:04:16,550 --> 00:04:13,920
reliability in the process that would

121
00:04:17,749 --> 00:04:16,560
definitely be a good thing so show us a

122
00:04:20,629 --> 00:04:17,759
little bit about what you're working on

123
00:04:21,670 --> 00:04:20,639
now with the the valve section of this

124
00:04:24,469 --> 00:04:21,680
okay

125
00:04:26,710 --> 00:04:24,479
this valve has a

126
00:04:29,189 --> 00:04:26,720
large disc that's in the flow path

127
00:04:30,230 --> 00:04:29,199
and that causes flow perturbations to

128
00:04:32,150 --> 00:04:30,240
the engine

129
00:04:33,670 --> 00:04:32,160
we're evaluating that using new cfd

130
00:04:35,830 --> 00:04:33,680
analysis tools

131
00:04:37,830 --> 00:04:35,840
to evaluate how to better design that

132
00:04:39,990 --> 00:04:37,840
disc for the new vehicle

133
00:04:41,430 --> 00:04:40,000
and get better engine performance great

134
00:04:43,350 --> 00:04:41,440
thanks very much jim

135
00:04:45,270 --> 00:04:43,360
we're here now with michelle monk she is

136
00:04:46,790 --> 00:04:45,280
the aero capture lead engineer here at

137
00:04:48,150 --> 00:04:46,800
marshall and michelle i find it

138
00:04:49,590 --> 00:04:48,160
interesting that at a center that

139
00:04:51,350 --> 00:04:49,600
concentrates so hard on propulsion

140
00:04:53,270 --> 00:04:51,360
you're actually working on stopping

141
00:04:55,350 --> 00:04:53,280
spacecraft not making them go that's

142
00:04:57,670 --> 00:04:55,360
right we're actually propellantless

143
00:04:59,830 --> 00:04:57,680
propulsion when a spacecraft is

144
00:05:01,990 --> 00:04:59,840
approaching a planet needs to slow down

145
00:05:04,390 --> 00:05:02,000
to get into a science orbit and so you

146
00:05:07,029 --> 00:05:04,400
can either do that with very expensive

147
00:05:08,710 --> 00:05:07,039
heavy fuel or you can use the atmosphere

148
00:05:10,550 --> 00:05:08,720
to slow you down and so that's what we

149
00:05:13,029 --> 00:05:10,560
do we take one pass through the

150
00:05:14,710 --> 00:05:13,039
atmosphere and we use the drag to slow

151
00:05:16,629 --> 00:05:14,720
our vehicle down and put it directly

152
00:05:18,629 --> 00:05:16,639
into its science orbit and that's where

153
00:05:20,629 --> 00:05:18,639
this very large heat shield comes into

154
00:05:23,749 --> 00:05:20,639
play tell us a little bit about this

155
00:05:25,909 --> 00:05:23,759
this is a two meter diameter

156
00:05:28,550 --> 00:05:25,919
carbon composite heat shield made by

157
00:05:30,950 --> 00:05:28,560
lockheed martin and it's a manufacturing

158
00:05:33,350 --> 00:05:30,960
demonstration of making a heat shield of

159
00:05:35,189 --> 00:05:33,360
this size in one piece and this isn't

160
00:05:37,270 --> 00:05:35,199
made of metal so this this makes it much

161
00:05:39,430 --> 00:05:37,280
lighter right right this is a carbon

162
00:05:41,510 --> 00:05:39,440
composite and this system is about 40

163
00:05:43,510 --> 00:05:41,520
percent lighter than the genesis sample

164
00:05:45,270 --> 00:05:43,520
return capsule system also it means you

165
00:05:46,550 --> 00:05:45,280
can put more science inside that's right

166
00:05:48,790 --> 00:05:46,560
well let's take a look at one of the

167
00:05:51,270 --> 00:05:48,800
prototypes you have over here

168
00:05:53,749 --> 00:05:51,280
can you tell us a little bit about this

169
00:05:56,629 --> 00:05:53,759
we've been doing about four years of

170
00:05:58,790 --> 00:05:56,639
technology development on the ground

171
00:06:01,749 --> 00:05:58,800
led by marshall and we've done lots of

172
00:06:04,790 --> 00:06:01,759
material testing and guidance algorithm

173
00:06:07,270 --> 00:06:04,800
development and simulation and now we're

174
00:06:09,830 --> 00:06:07,280
proposing to do a validation of the

175
00:06:12,950 --> 00:06:09,840
aerocapture maneuver at earth and this

176
00:06:15,749 --> 00:06:12,960
is a full-scale prototype vehicle that

177
00:06:18,469 --> 00:06:15,759
we would use to do that and if selected

178
00:06:20,469 --> 00:06:18,479
marshall will supply the flight heat

179
00:06:24,070 --> 00:06:20,479
shield and the back shell

180
00:06:25,830 --> 00:06:24,080
for that space vehicle and jpl will

181
00:06:28,309 --> 00:06:25,840
supply the spacecraft for that and will

182
00:06:29,590 --> 00:06:28,319
fly in 2010. 2010 not too far away

183
00:06:31,110 --> 00:06:29,600
that's right well michelle thanks very

184
00:06:32,309 --> 00:06:31,120
much for showing us your technology here

185
00:06:34,629 --> 00:06:32,319
today and we look forward to seeing it

186
00:06:36,070 --> 00:06:34,639
fly thanks

187
00:06:36,790 --> 00:06:36,080
hey bill look at all this cool stuff i

188
00:06:38,550 --> 00:06:36,800
got

189
00:06:40,790 --> 00:06:38,560
well i guess it has been a neat day here

190
00:06:42,309 --> 00:06:40,800
at the research and technology expo yeah

191
00:06:44,469 --> 00:06:42,319
it has but it's also been interesting to

192
00:06:45,749 --> 00:06:44,479
find out how someone has an idea and

193
00:06:47,350 --> 00:06:45,759
then turns that into hardware and

194
00:06:48,950 --> 00:06:47,360
technology that may take us back to the

195
00:06:50,230 --> 00:06:48,960
moon and even to mars someday that's

196
00:06:52,390 --> 00:06:50,240
right and all of it designed or

197
00:06:54,230 --> 00:06:52,400
