Music under narration.

5
00:00:18,814 --> 00:00:20,043
Getting tomorrow's

6
00:00:20,078 --> 00:00:20,795
technology ready

7
00:00:20,830 --> 00:00:21,372
for the future is the

8
00:00:21,531 --> 00:00:22,347
purpose of the Technology

9
00:00:22,491 --> 00:00:23,339
Demonstration Missions

10
00:00:24,027 --> 00:00:26,074
Program. Taking today's

11
00:00:26,268 --> 00:00:27,499
most promising exploration

12
00:00:27,948 --> 00:00:28,986
technology and raising it

13
00:00:29,756 --> 00:00:30,410
to the level of maturity

14
00:00:30,716 --> 00:00:31,914
that mission planners

15
00:00:31,949 --> 00:00:33,291
require, means that TDM puts

16
00:00:33,404 --> 00:00:35,226
the technology to the

17
00:00:35,261 --> 00:00:38,011
test. The projects include

18
00:00:38,046 --> 00:00:39,515
communication, materials,

19
00:00:39,550 --> 00:00:41,547
propulsion and robotics.

20
00:00:41,582 --> 00:00:44,154
Key to any exploration

21
00:00:44,189 --> 00:00:46,026
program is effective

22
00:00:46,061 --> 00:00:47,722
communication. Current

23
00:00:47,757 --> 00:00:49,402
technology is hitting a bandwidth

24
00:00:49,437 --> 00:00:51,483
and wavelength ceiling.

25
00:00:51,518 --> 00:00:52,987
Tomorrow's missions will

26
00:00:53,022 --> 00:00:55,355
need a new technology. NASA

27
00:00:55,390 --> 00:00:57,179
is leading the effort to

28
00:00:57,214 --> 00:00:58,810
make laser light reinforce

29
00:00:58,845 --> 00:01:01,050
the current radio or RF

30
00:01:01,085 --> 00:01:02,954
based communications. The

31
00:01:02,989 --> 00:01:04,795
Laser Communications Relay

32
00:01:04,830 --> 00:01:06,458
Demonstration or "Laser

33
00:01:06,493 --> 00:01:08,523
Comm" project will provide

34
00:01:08,558 --> 00:01:10,442
an orbital test-bed for a

35
00:01:10,477 --> 00:01:11,915
wide variety of scenarios

36
00:01:11,950 --> 00:01:13,691
to simulate future

37
00:01:13,726 --> 00:01:15,579
missions. In the near future

38
00:01:15,614 --> 00:01:17,019
laser communications could

39
00:01:17,054 --> 00:01:18,442
increase the amount of

40
00:01:18,477 --> 00:01:20,122
information to tens of

41
00:01:20,157 --> 00:01:22,634
gigabits per second. This

42
00:01:22,669 --> 00:01:24,106
would be an improvement of

43
00:01:24,141 --> 00:01:26,827
data rates of between 10-100

44
00:01:26,862 --> 00:01:29,451
times. The project will

45
00:01:29,486 --> 00:01:31,227
use laser light transmitted

46
00:01:31,262 --> 00:01:32,859
to a satellite payload and

47
00:01:32,894 --> 00:01:34,746
back to an earth station

48
00:01:34,781 --> 00:01:36,186
to simulate and test a

49
00:01:36,221 --> 00:01:38,091
large number of possible

50
00:01:38,126 --> 00:01:39,930
mission scenarios. Another

51
00:01:39,965 --> 00:01:42,314
foundational technology being

52
00:01:42,349 --> 00:01:44,699
improved by the TDM Program

53
00:01:44,734 --> 00:01:46,139
involves a basic component

54
00:01:46,174 --> 00:01:48,523
of all exploration missionsů

55
00:01:48,558 --> 00:01:50,907
time. The Deep Space

56
00:01:50,942 --> 00:01:53,098
Atomic Clock project promises

57
00:01:53,133 --> 00:01:54,842
to reduce cost, improve

58
00:01:54,877 --> 00:01:56,954
space navigation, data

59
00:01:56,989 --> 00:01:58,746
quality and the next GPS

60
00:01:58,781 --> 00:02:01,274
system. To test this

61
00:02:01,309 --> 00:02:02,954
concept, the project will fly

62
00:02:02,989 --> 00:02:05,179
the deep space atomic clock

63
00:02:05,214 --> 00:02:07,451
along with a GPS receiver

64
00:02:07,486 --> 00:02:08,938
on a commercial communication

65
00:02:08,973 --> 00:02:11,034
satellite. Ground

66
00:02:11,069 --> 00:02:12,522
based systems require

67
00:02:12,557 --> 00:02:14,394
two-way communication, with an

68
00:02:14,429 --> 00:02:15,962
onboard atomic clock

69
00:02:15,997 --> 00:02:17,754
DSAC allows for 1 way

70
00:02:17,789 --> 00:02:20,539
navigation-using NASA's Deep

71
00:02:20,574 --> 00:02:22,635
Space Network more efficiently!

72
00:02:22,670 --> 00:02:24,315
Eventually this will

73
00:02:24,350 --> 00:02:25,994
enable deep space autonomous

74
00:02:26,029 --> 00:02:28,506
navigation. Communications

75
00:02:28,541 --> 00:02:30,378
and science payloads

76
00:02:30,413 --> 00:02:31,786
need advanced warning of

77
00:02:31,821 --> 00:02:33,658
Solar Flares. One way to

78
00:02:33,693 --> 00:02:35,114
do that includes

79
00:02:35,149 --> 00:02:36,827
station-keeping capabilities like

80
00:02:36,862 --> 00:02:38,363
the current NOAA solar

81
00:02:38,398 --> 00:02:40,363
activity warning instrument.

82
00:02:40,398 --> 00:02:42,507
The TDM Solar Sail project

83
00:02:42,542 --> 00:02:44,028
takes a previously tested

84
00:02:44,063 --> 00:02:46,362
propulsion technology and

85
00:02:46,397 --> 00:02:47,610
infuses it into an even

86
00:02:47,645 --> 00:02:48,954
better warning system 2

87
00:02:48,989 --> 00:02:51,642
times closer to the sun. The

88
00:02:51,677 --> 00:02:53,371
Solar Sail project

89
00:02:53,406 --> 00:02:54,843
pushes the technology to a

90
00:02:54,878 --> 00:02:56,507
practical application while

91
00:02:56,542 --> 00:02:58,059
simultaneously maturing the

92
00:02:58,094 --> 00:02:59,772
system so that future

93
00:02:59,807 --> 00:03:01,451
mission planners can chose it

94
00:03:01,486 --> 00:03:03,098
for a whole range of missions.

95
00:03:03,133 --> 00:03:05,738
All of NASA's Technology

96
00:03:05,773 --> 00:03:07,211
Demonstration Missions are

97
00:03:07,246 --> 00:03:09,051
infusing mature technology

98
00:03:09,086 --> 00:03:10,683
from the realm of tested

99
00:03:10,718 --> 00:03:12,122
to ready and proven,

100
00:03:12,157 --> 00:03:13,499
but one of those

101
00:03:13,534 --> 00:03:14,731
demonstrations tests the very

102
00:03:14,766 --> 00:03:16,171
materials that are used for

103
00:03:16,206 --> 00:03:18,267
space craft construction.

104
00:03:18,302 --> 00:03:19,740
That project is a continuation

105
00:03:19,775 --> 00:03:21,610
of a heritage project

106
00:03:21,645 --> 00:03:23,146
called MISSE; Materials

107
00:03:23,181 --> 00:03:24,458
International Space Station

108
00:03:24,493 --> 00:03:26,202
Experiment. Building on

109
00:03:26,237 --> 00:03:27,419
the previous missions,

110
00:03:27,454 --> 00:03:28,986
MISSE-X seeks to provide

111
00:03:29,021 --> 00:03:30,395
low-cost access to space

112
00:03:30,430 --> 00:03:31,983
technology experiments

113
00:03:32,018 --> 00:03:33,796
using robotically installed

114
00:03:33,831 --> 00:03:35,796
"plug and play" features.

115
00:03:35,831 --> 00:03:37,442
MISSE-X plans to monitor the

116
00:03:37,477 --> 00:03:38,995
payloads by collecting

117
00:03:39,030 --> 00:03:41,621
data and photographic images

118
00:03:41,656 --> 00:03:42,610
in near real-time. This

119
00:03:42,645 --> 00:03:43,731
allows for faster testing

120
00:03:43,766 --> 00:03:45,155
of materials and greater

121
00:03:45,190 --> 00:03:46,963
opportunities for educators

122
00:03:46,998 --> 00:03:48,274
to have easy access to

123
00:03:48,309 --> 00:03:50,131
the ISS as an experimental

124
00:03:50,166 --> 00:03:52,498
platform. Maturing materials

125
00:03:52,533 --> 00:03:54,516
and technology continues

126
00:03:54,551 --> 00:03:55,730
to be an objective of

127
00:03:55,765 --> 00:03:57,730
the TDM Program. Sometimes

128
00:03:57,765 --> 00:03:59,106
that means putting instruments

129
00:03:59,141 --> 00:04:00,401
on the spacecraft of

130
00:04:00,436 --> 00:04:01,970
other NASA Missions to further

131
00:04:02,005 --> 00:04:03,746
our collective knowledge.

132
00:04:03,781 --> 00:04:05,665
One project that does that is

133
00:04:05,700 --> 00:04:07,602
MEDLI. MEDLI stands for Mars

134
00:04:07,637 --> 00:04:10,546
Science Laboratory Entry Descent

135
00:04:10,581 --> 00:04:12,425
and Landing Instrumentation.

136
00:04:12,460 --> 00:04:13,784
MEDLI is an instrumentation

137
00:04:13,819 --> 00:04:15,193
suite embedded in and behind the

138
00:04:15,228 --> 00:04:17,720
heat shield of the Mars Science

139
00:04:17,755 --> 00:04:19,433
Laboratory now on its way to a

140
00:04:19,468 --> 00:04:21,673
Martian landing this summer.

141
00:04:21,708 --> 00:04:22,985
The instruments gather real-time

142
00:04:23,020 --> 00:04:24,713
data on the atmosphere, thermal

143
00:04:24,748 --> 00:04:26,345
protection system, or heat

144
00:04:26,380 --> 00:04:29,177
shield, and aerodynamics during

145
00:04:29,212 --> 00:04:31,736
entry and descent.  The MEDLI

146
00:04:31,771 --> 00:04:33,383
data will improve modeling and

147
00:04:33,418 --> 00:04:35,047
predictive capabilities for future

148
00:04:35,082 --> 00:04:37,576
missions, ensuring safer and

149
00:04:37,611 --> 00:04:39,096
less expensive missions to a

150
00:04:39,131 --> 00:04:41,368
larger variety of destinations.

151
00:04:41,403 --> 00:04:47,767
Along with the MEDLI data, NASA

152
00:04:47,802 --> 00:04:49,415
will see the fruits of research

153
00:04:49,450 --> 00:04:51,637
into entry in low density

154
00:04:51,672 --> 00:04:53,493
atmospheres like Mar's with the

155
00:04:53,528 --> 00:04:55,204
Low Density Supersonic Decelerator

156
00:04:55,239 --> 00:04:59,573
or LDSD project. On Mars for

157
00:04:59,608 --> 00:05:01,684
example, increasingly massive

158
00:05:01,719 --> 00:05:03,221
payloads and eventually human

159
00:05:03,256 --> 00:05:05,683
missions will require new ways to

160
00:05:05,718 --> 00:05:08,292
slow down to subsonic speeds, high

161
00:05:08,327 --> 00:05:10,676
in the thin Martian Atmosphere,

162
00:05:10,711 --> 00:05:12,467
allowing more landing site

163
00:05:12,502 --> 00:05:14,964
options. These heavier spacecraft

164
00:05:14,999 --> 00:05:16,931
will need large drag generating

165
00:05:16,966 --> 00:05:19,332
devices and the LDSD project

166
00:05:19,367 --> 00:05:21,555
will test 3 of them. Two of the

167
00:05:21,590 --> 00:05:27,300
test articles will be inflatable

168
00:05:27,335 --> 00:05:28,387
inner tube type devices that

169
00:05:28,422 --> 00:05:29,411
surround the entry capsule.

170
00:05:29,446 --> 00:05:30,691
These 6 and 9 meter devices will

171
00:05:30,726 --> 00:05:31,954
be flown at supersonic speeds

172
00:05:31,989 --> 00:05:34,705
high in the earth's atmosphere.

173
00:05:34,740 --> 00:05:36,083
The third device will be a

174
00:05:36,118 --> 00:05:38,163
large 30 meter parachute tested

175
00:05:38,198 --> 00:05:39,778
several times to collect data

176
00:05:39,813 --> 00:05:42,610
for future exploration missions.

177
00:05:42,645 --> 00:05:44,561
All the previous exploration

178
00:05:44,596 --> 00:05:46,370
enabling technologies will be

179
00:05:46,405 --> 00:05:47,330
dependent on propulsion to get

180
00:05:47,365 --> 00:05:49,265
to their destination. Long

181
00:05:49,300 --> 00:05:51,298
duration missions require special

182
00:05:51,333 --> 00:05:53,009
considerations for the cryogenic

183
00:05:53,044 --> 00:05:54,881
propellant likely to be used

184
00:05:54,916 --> 00:05:57,553
for human exploration missions.

185
00:05:57,588 --> 00:05:59,393
On short missions, the natural

186
00:05:59,428 --> 00:06:01,011
boiling off of cryogenic fluids

187
00:06:01,046 --> 00:06:03,098
is not as serious a concern,

188
00:06:03,133 --> 00:06:04,177
but on long missions it

189
00:06:04,212 --> 00:06:05,761
becomes critically important.

190
00:06:05,796 --> 00:06:08,426
Propellants are heavy and expensive

191
00:06:08,461 --> 00:06:10,473
to lift to orbit and therefore

192
00:06:10,508 --> 00:06:12,535
too precious to lose. Anything

193
00:06:12,570 --> 00:06:14,152
we can learn to minimize this

194
00:06:14,187 --> 00:06:17,416
pays back huge dividends! There

195
00:06:17,451 --> 00:06:19,064
are a variety of approaches to

196
00:06:19,099 --> 00:06:21,304
meet this challenge including

197
00:06:21,339 --> 00:06:23,064
passive systems like insulation

198
00:06:23,099 --> 00:06:25,704
and active ones like refrigeration.

199
00:06:25,739 --> 00:06:27,768
Another important part

200
00:06:27,803 --> 00:06:29,192
of this research is lossless

201
00:06:29,227 --> 00:06:32,263
transfer of cryogenic fluids and

202
00:06:32,298 --> 00:06:33,703
accurate measurement.  Once

203
00:06:33,738 --> 00:06:35,591
completed, the flight demonstration

204
00:06:35,626 --> 00:06:38,790
technology projects will be

205
00:06:38,825 --> 00:06:39,847
extremely valuable, enabling

206
00:06:39,882 --> 00:06:40,758
us to reach our exploration

207
00:06:40,793 --> 00:06:44,119
goalsů beyond Earth orbit. As we

208
00:06:44,154 --> 00:06:46,487
begin to land even more ambitious

209
00:06:46,522 --> 00:06:48,837
crewed and robotic missions,

210
00:06:48,872 --> 00:06:50,709
one of the most challenging

211
00:06:50,744 --> 00:06:52,341
aspects of those missions will be

212
00:06:52,376 --> 00:06:53,749
landing in a large variety

213
00:06:53,784 --> 00:06:55,301
of conditions. The Autonomous

214
00:06:55,336 --> 00:06:56,949
Landing and Hazard Avoidance

215
00:06:56,984 --> 00:06:59,797
Technologyů ALHAT, uses sensors to

216
00:06:59,832 --> 00:07:02,148
rapidly map the ground in 3D,

217
00:07:02,183 --> 00:07:04,148
and measure range and velocity far

218
00:07:04,183 --> 00:07:06,020
more accurately than existing

219
00:07:06,055 --> 00:07:08,916
radar systems. ALHAT has already

220
00:07:08,951 --> 00:07:10,356
made tremendous strides in

221
00:07:10,391 --> 00:07:11,860
meeting the challenge of safely

222
00:07:11,895 --> 00:07:13,972
landing in some very difficult

223
00:07:14,007 --> 00:07:16,051
terrain. In the near future ALHAT

224
00:07:16,086 --> 00:07:17,844
will be integrated with a

225
00:07:17,879 --> 00:07:19,346
vertical test bed named Morpheus

226
00:07:19,381 --> 00:07:22,130
to test and demonstrate advanced

227
00:07:22,165 --> 00:07:24,306
propulsion and safe landing

228
00:07:24,341 --> 00:07:26,338
techniques; critical for future

229
00:07:26,373 --> 00:07:28,232
missions. Some of those future

230
00:07:28,267 --> 00:07:30,361
missions will include humans,

231
00:07:30,396 --> 00:07:32,873
other robots, and some will

232
00:07:32,908 --> 00:07:34,843
be a symbiotic combination of

233
00:07:34,878 --> 00:07:37,433
both. The Telerobotics project

234
00:07:37,468 --> 00:07:39,898
is working onboard the International

235
00:07:39,933 --> 00:07:41,497
Space Station, integrating

236
00:07:41,532 --> 00:07:43,322
robotics seamlessly into the

237
00:07:43,357 --> 00:07:45,576
nation's space exploration

238
00:07:45,611 --> 00:07:47,465
goals. From measuring environmental

239
00:07:47,500 --> 00:07:49,801
conditions on the ISS with

240
00:07:49,836 --> 00:07:51,801
free-flying robots called "Smart

241
00:07:51,836 --> 00:07:54,377
Spheres" to dexterous two armed

242
00:07:54,412 --> 00:07:57,096
humanoid robots like "Robonaut2,"

243
00:07:57,131 --> 00:07:58,825
NASA sees a growing role for

244
00:07:58,860 --> 00:08:01,192
intelligent robotic devices.

245
00:08:01,227 --> 00:08:04,088
TeleRobots can also save precious

246
00:08:04,123 --> 00:08:05,416
resources by doing Extra-vehicular

247
00:08:05,451 --> 00:08:07,529
activities. Working before

248
00:08:07,564 --> 00:08:10,518
and after humans. Each of these

249
00:08:10,553 --> 00:08:12,359
programs has been carefully

250
00:08:12,394 --> 00:08:14,263
chosen because they contribute

251
00:08:14,298 --> 00:08:15,878
critical technology and functional

252
00:08:15,913 --> 00:08:17,478
knowledge to our nation's

253
00:08:17,513 --> 00:08:20,342
exploration objectives.  They improve

254
00:08:20,377 --> 00:08:23,190
safety and reduce cost. The

255
00:08:23,225 --> 00:08:25,302
Technology Demonstration Missions

256
00:08:25,337 --> 00:08:27,431
Program provides new knowledge

257
00:08:27,466 --> 00:08:29,863
and capabilities needed to enable
