1
00:00:00,858 --> 00:00:04,656
I was 17 when I chose my career.

2
00:00:05,617 --> 00:00:08,000
I was standing outside

3
00:00:08,000 --> 00:00:11,238
on a hot summer night in Florida

4
00:00:11,238 --> 00:00:13,565
and just a few miles from the ocean.

5
00:00:14,798 --> 00:00:18,195
I was waiting for a miracle to happen.

6
00:00:19,540 --> 00:00:23,386
That summer I was privileged
to work as an intern

7
00:00:23,386 --> 00:00:25,998
at NASA's Kennedy Space Center,

8
00:00:25,998 --> 00:00:28,282
and the miracle I was waiting for

9
00:00:28,282 --> 00:00:31,826
was the launch
of the Columbia Space Shuttle,

10
00:00:31,826 --> 00:00:35,486
carrying the Chandra X-Ray Observatory,

11
00:00:35,486 --> 00:00:41,667
a telescope that would allow scientists
to peer into the edge of black holes.

12
00:00:42,841 --> 00:00:45,755
The entire sky filled with light.

13
00:00:47,078 --> 00:00:50,277
And it was as if it was daytime
in the middle of the night.

14
00:00:51,149 --> 00:00:54,880
Soon, we could feel the rumble
of the engines vibrating in our chests.

15
00:00:56,003 --> 00:00:58,406
And it wasn't a miracle;

16
00:00:58,406 --> 00:01:02,357
it was the combined effort
of a team of thousands of people

17
00:01:02,357 --> 00:01:03,672
who worked together

18
00:01:03,672 --> 00:01:06,956
to make was seemed impossible a reality.

19
00:01:07,991 --> 00:01:11,720
And I wanted to join that team.

20
00:01:12,872 --> 00:01:17,658
So I decided to apply to a university
where I could study aerospace engineering,

21
00:01:17,658 --> 00:01:19,008
and the following year,

22
00:01:19,008 --> 00:01:21,718
I started at MIT
in my engineering training

23
00:01:21,718 --> 00:01:24,460
and joined a student project
building space robots.

24
00:01:25,146 --> 00:01:27,871
And everything was going as I planned,

25
00:01:27,871 --> 00:01:32,509
except I was confused
about something important.

26
00:01:33,768 --> 00:01:36,781
Now, my confusion arose
in my summer breaks.

27
00:01:37,534 --> 00:01:40,915
I traveled to a school in Kenya,

28
00:01:40,915 --> 00:01:45,583
and there I volunteered
with girls ages five to 17,

29
00:01:45,583 --> 00:01:50,478
giving them lessons in English
and math and science.

30
00:01:51,193 --> 00:01:53,835
And they taught me songs in Swahili.

31
00:01:55,330 --> 00:01:58,907
And mostly, I just spent time
getting to know the girls,

32
00:01:58,907 --> 00:02:00,340
enjoying their presence.

33
00:02:00,804 --> 00:02:03,225
And I saw that these girls,

34
00:02:03,225 --> 00:02:04,942
and the leaders in their community,

35
00:02:04,942 --> 00:02:07,871
they were overcoming important barriers

36
00:02:07,871 --> 00:02:12,695
to allow these girls to have
the best possible chances in life ...

37
00:02:12,695 --> 00:02:16,443
and I wanted to join that team.

38
00:02:16,931 --> 00:02:20,012
I wanted to be part of a team
that would help break down barriers

39
00:02:20,012 --> 00:02:22,696
and improve the lives
of girls around the world,

40
00:02:22,696 --> 00:02:25,697
but I was worried that studying
aerospace engineering

41
00:02:25,697 --> 00:02:27,202
wasn't the most useful.

42
00:02:27,202 --> 00:02:28,780
I was worried this team in Kenya

43
00:02:28,780 --> 00:02:31,963
couldn't use the technology
I was learning about space.

44
00:02:33,345 --> 00:02:36,323
But thankfully, I still learned
that I was wrong.

45
00:02:37,527 --> 00:02:39,967
I came back and interned at NASA again,

46
00:02:39,967 --> 00:02:41,148
and this time,

47
00:02:41,148 --> 00:02:42,911
a mentor taught me

48
00:02:42,911 --> 00:02:48,131
that countries like Kenya had been
involved using space technology

49
00:02:48,131 --> 00:02:49,248
for decades

50
00:02:49,248 --> 00:02:51,357
to improve the lives
in their own countries.

51
00:02:51,745 --> 00:02:56,763
And then I knew that I could have
a career in space and in development.

52
00:02:57,958 --> 00:02:59,316
This idea is not new.

53
00:02:59,825 --> 00:03:04,167
In fact, in 1967, the nations
of the world came together

54
00:03:04,167 --> 00:03:06,822
to write the Outer Space Treaty.

55
00:03:07,607 --> 00:03:10,293
This treaty made a bold statement,

56
00:03:10,293 --> 00:03:14,525
saying that "the exploration
and use of outer space

57
00:03:14,525 --> 00:03:18,732
should be carried on
for the benefit of all peoples,

58
00:03:18,732 --> 00:03:23,430
irrespective of their level
of economic or scientific development."

59
00:03:25,173 --> 00:03:27,470
We have not truly lived up to this ideal,

60
00:03:27,470 --> 00:03:30,689
although people have worked
for decades to make this a reality.

61
00:03:31,826 --> 00:03:35,880
Forces such as colonialism and racism

62
00:03:35,880 --> 00:03:38,260
and gender inequality

63
00:03:38,260 --> 00:03:42,801
have actually excluded many people
from the benefits of space,

64
00:03:42,801 --> 00:03:46,365
and caused us to believe
that space is for the few,

65
00:03:46,365 --> 00:03:48,793
or the rich or elite.

66
00:03:49,850 --> 00:03:52,327
But we cannot afford this attitude,

67
00:03:52,327 --> 00:03:55,481
because the world is engaged
in a vital mission

68
00:03:55,481 --> 00:03:57,376
to improve life for everyone.

69
00:03:58,313 --> 00:04:04,073
Our roadmap for this mission comes from
the 17 Sustainable Development Goals

70
00:04:04,073 --> 00:04:05,438
of the United Nations.

71
00:04:05,808 --> 00:04:08,612
All the member states
of the United Nations have agreed

72
00:04:08,612 --> 00:04:11,701
that these are priorities
between now and 2030.

73
00:04:12,605 --> 00:04:18,453
These goals give us our key moments
and opportunities of our time --

74
00:04:18,453 --> 00:04:21,447
opportunities to end extreme poverty,

75
00:04:21,447 --> 00:04:25,862
to insure that everyone has access
to food and clean water.

76
00:04:27,815 --> 00:04:31,861
We must pursue these goals
as a global community,

77
00:04:31,861 --> 00:04:36,898
and technology from space
supports sustainable development,

78
00:04:36,898 --> 00:04:40,030
and in fact there are six space services

79
00:04:40,030 --> 00:04:43,823
that can help us pursue
the Sustainable Development Goals.

80
00:04:44,789 --> 00:04:46,078
Over the next few minutes,

81
00:04:46,078 --> 00:04:47,986
let's explore these six services,

82
00:04:47,986 --> 00:04:51,529
and see examples of just a few
of the goals they help support.

83
00:04:51,529 --> 00:04:52,526
You ready?

84
00:04:53,234 --> 00:04:54,227
OK.

85
00:04:54,227 --> 00:04:58,503
Communication satellites provide access
to phone and internet service

86
00:04:58,503 --> 00:05:00,241
to almost any location on earth.

87
00:05:00,721 --> 00:05:04,110
This is particularly important
during times of disaster recovery.

88
00:05:04,523 --> 00:05:08,131
When Typhoon Haiyan
struck the Philippines,

89
00:05:08,131 --> 00:05:11,005
the local communication netwworks
needed to be repaired,

90
00:05:11,005 --> 00:05:14,256
and teams brought in inflatable
communication antennas

91
00:05:14,256 --> 00:05:15,978
that could link to satellites.

92
00:05:16,209 --> 00:05:18,786
This was useful during the time
of repair and recovery.

93
00:05:19,569 --> 00:05:22,807
Positioning satellites
tell us where we are

94
00:05:22,807 --> 00:05:24,663
by telling us where they are.

95
00:05:25,975 --> 00:05:30,021
Scientists can use this technology
to track endagered wildlife.

96
00:05:30,804 --> 00:05:33,261
This turtle has been fitted with a system

97
00:05:33,261 --> 00:05:37,850
that allows it to receive location
information from positioning satellites,

98
00:05:37,850 --> 00:05:40,051
and they send the location information

99
00:05:40,051 --> 00:05:42,270
to scientists via
communication satellites.

100
00:05:43,211 --> 00:05:46,491
Scientists can use this knowledge
to then make better policies

101
00:05:46,491 --> 00:05:48,901
and help determine how
to keep these animals alive.

102
00:05:50,500 --> 00:05:52,601
Earth observation satellites.

103
00:05:52,948 --> 00:05:55,229
They tell us what's going on
in our environment.

104
00:05:55,576 --> 00:05:56,864
Now right now,

105
00:05:56,864 --> 00:06:01,975
there are about 150 satellites
operated by over 60 government agencies,

106
00:06:01,975 --> 00:06:04,113
and these are just
those observing the earth.

107
00:06:04,217 --> 00:06:06,612
And meanwhile, companies
are adding to this list.

108
00:06:07,157 --> 00:06:10,837
Most of the governments provide the data
from the satellites for free online.

109
00:06:11,018 --> 00:06:14,328
Some of these satellites
provide images like this,

110
00:06:14,328 --> 00:06:16,473
that show what you
would see from a camera.

111
00:06:16,763 --> 00:06:19,519
This is an image showing
agricultural land in Kansas.

112
00:06:20,742 --> 00:06:23,651
However, the majority
of the earth observation satellites

113
00:06:23,651 --> 00:06:25,633
don't take pictures at all.

114
00:06:25,898 --> 00:06:27,225
They take measurements.

115
00:06:27,449 --> 00:06:30,649
And they combine these measurements
with complex computer models

116
00:06:30,649 --> 00:06:32,779
and make beautiful, global visualizations

117
00:06:32,779 --> 00:06:33,877
such as this one,

118
00:06:33,877 --> 00:06:35,807
showing the ocean currents

119
00:06:35,807 --> 00:06:37,831
and the temperature
of the ocean, globally.

120
00:06:39,418 --> 00:06:45,081
Or we can look at the salt and smoke
and dust in the atmosphere.

121
00:06:47,611 --> 00:06:50,286
Or the rainfall and snowfall, globally.

122
00:06:53,175 --> 00:06:58,176
As well as the annual cycle of vegetation
on land and in the ocean.

123
00:07:00,065 --> 00:07:04,521
Now, scientists can take this information
about the rainfall and the vegetation,

124
00:07:04,521 --> 00:07:07,960
and use it to understand
what areas on earth are in danger

125
00:07:07,960 --> 00:07:09,801
of a famine or a drought,

126
00:07:09,801 --> 00:07:12,426
and provide that information
to aid organizations

127
00:07:12,426 --> 00:07:16,243
so they can be prepared with food aid
before the hunger becomes severe.

128
00:07:16,960 --> 00:07:21,697
In space, we have an orbiting laboratory
on the International Space Station.

129
00:07:22,773 --> 00:07:26,894
The vehicle, and everything inside,
are in a form of freefall around the earth

130
00:07:26,894 --> 00:07:29,224
and they don't experience
the effect of gravity.

131
00:07:30,219 --> 00:07:32,481
And because of this,
we call it microgravity.

132
00:07:33,463 --> 00:07:36,012
When astronauts are in
the microgravity environment,

133
00:07:36,012 --> 00:07:39,306
their bodies react
as if they're aging rapidly.

134
00:07:39,936 --> 00:07:42,328
Their bones and muscles weaken,

135
00:07:42,328 --> 00:07:45,779
and their cardiovascualar system
and their immune system change.

136
00:07:47,140 --> 00:07:50,324
As scientists study how to keep
astronauts healthy in space,

137
00:07:50,324 --> 00:07:53,777
we can take the exercises
and techniques we use for astronauts

138
00:07:53,777 --> 00:07:55,753
and transfer them to people on earth

139
00:07:55,753 --> 00:07:57,150
to improve our health here.

140
00:07:57,604 --> 00:08:01,098
Often as we develop technology
for astronauts and exploration,

141
00:08:01,098 --> 00:08:02,391
or for spacecraft,

142
00:08:02,391 --> 00:08:05,679
we can also tranfer those inventions
to improve life on earth.

143
00:08:05,837 --> 00:08:07,247
Here's one of my favorites.

144
00:08:07,247 --> 00:08:09,026
It's a water filtration system,

145
00:08:09,026 --> 00:08:12,072
and a key component of it
is based on the technology

146
00:08:12,072 --> 00:08:14,135
to filter wastewater on the space station.

147
00:08:14,439 --> 00:08:16,324
It's now being used around the world.

148
00:08:16,680 --> 00:08:20,313
Space is also an infinite
source of inspiration,

149
00:08:20,313 --> 00:08:21,517
through education,

150
00:08:21,517 --> 00:08:23,174
through research and astronomy,

151
00:08:23,174 --> 00:08:26,306
and that age-old experience of stargazing.

152
00:08:26,776 --> 00:08:28,632
Now, countries around the world

153
00:08:28,632 --> 00:08:31,467
are engaging in advancing
their own development

154
00:08:31,467 --> 00:08:35,314
by increasing their local knowledge
of engineering, and science and space.

155
00:08:35,704 --> 00:08:39,571
Let's meet some of the world's
newest satellite engineers.

156
00:08:40,149 --> 00:08:43,300
This is Elyka Abello from Venezuela.

157
00:08:44,264 --> 00:08:47,346
Elyka is training as a satellite engineer

158
00:08:47,346 --> 00:08:50,162
as part of her national
satellite program in Venezuela.

159
00:08:50,836 --> 00:08:52,596
She has designed a software tool

160
00:08:52,596 --> 00:08:56,196
that allows her team to better design
the power systems for engineering.

161
00:08:58,100 --> 00:09:00,875
This is [Adele Castillo-Doran],

162
00:09:00,875 --> 00:09:01,983
from the Philippines.

163
00:09:02,474 --> 00:09:05,580
Adele is both a meteorologist
and a satellite engineer,

164
00:09:05,580 --> 00:09:08,956
and she uses data from satellites
in her weather forecasting.

165
00:09:10,549 --> 00:09:12,122
And finally, meet [Toula.]

166
00:09:12,708 --> 00:09:14,559
[Toula] is from the Sudan,

167
00:09:14,559 --> 00:09:17,773
and as she was studying electrical
engineering as an undergraduate

168
00:09:17,773 --> 00:09:19,039
in Khartoum,

169
00:09:19,039 --> 00:09:21,977
she and several students decided
to build their own satellite.

170
00:09:21,977 --> 00:09:24,900
And later, [Toula] earned a scholarship

171
00:09:24,900 --> 00:09:27,638
to study satellite engineering
at the graduate level.

172
00:09:29,183 --> 00:09:31,480
These stories that I've shared with you

173
00:09:31,480 --> 00:09:35,528
all illustrate that space truly is useful
for sustainable development

174
00:09:35,528 --> 00:09:37,302
for the benefit of all peoples.

175
00:09:38,016 --> 00:09:40,487
But we have more work to do

176
00:09:40,487 --> 00:09:44,305
because there are still barriers
that exclude people from space

177
00:09:44,305 --> 00:09:46,448
and limit the impact of this technology.

178
00:09:47,402 --> 00:09:48,594
For many people,

179
00:09:48,594 --> 00:09:50,997
earth observation data is complex.

180
00:09:51,576 --> 00:09:54,288
And satellite communication
services are too expensive.

181
00:09:54,966 --> 00:09:58,280
And microgravity research
just appears to be inaccessible.

182
00:09:59,671 --> 00:10:04,409
This is what motivates my work
as a professor at MIT's Media Lab.

183
00:10:04,871 --> 00:10:09,995
I've recently founded a new research group
called Space Enabled.

184
00:10:10,829 --> 00:10:15,699
We are working to tear down these barriers
that limit the benefits of space,

185
00:10:15,699 --> 00:10:18,292
and we're also going to develop
the future applications

186
00:10:18,292 --> 00:10:21,572
that will continue to contribute
to sustainable development.

187
00:10:22,533 --> 00:10:24,316
We'll keep on this work

188
00:10:24,316 --> 00:10:28,894
until we can truly say that space
is for the benefit of all peoples,

189
00:10:28,894 --> 00:10:32,032
and we are all space enabled.

190
00:10:32,815 --> 00:10:33,819
Thank you.

191
00:10:33,819 --> 00:10:36,445
