6 space technologies we can use to improve life on Earth

  • 0:01 - 0:05
    I was 17 when I chose my career.
  • 0:06 - 0:08
    I was standing outside
  • 0:08 - 0:10
    on a hot summer night in Florida
  • 0:11 - 0:14
    and just a few miles from the ocean.
  • 0:15 - 0:18
    I was waiting for a miracle to happen.
  • 0:20 - 0:23
    That summer, I was privileged
    to work as an intern
  • 0:23 - 0:25
    at NASA's Kennedy Space Center,
  • 0:26 - 0:28
    and the miracle I was waiting for
  • 0:28 - 0:32
    was the launch
    of the Columbia Space Shuttle
  • 0:32 - 0:35
    carrying the Chandra X-Ray Observatory,
  • 0:35 - 0:42
    a telescope that would allow scientists
    to peer into the edge of black holes.
  • 0:43 - 0:46
    The entire sky filled with light.
  • 0:47 - 0:50
    And it was as if it was daytime
    in the middle of the night.
  • 0:51 - 0:55
    Soon, we could feel the rumble
    of the engines vibrating in our chests.
  • 0:56 - 0:58
    And it wasn't a miracle;
  • 0:58 - 1:02
    it was the combined effort
    of a team of thousands of people
  • 1:02 - 1:04
    who worked together
  • 1:04 - 1:07
    to make was seemed impossible a reality.
  • 1:08 - 1:12
    And I wanted to join that team.
  • 1:13 - 1:17
    So I decided to apply to a university
    where I could study aerospace engineering.
  • 1:18 - 1:19
    And the following year,
  • 1:19 - 1:22
    I started at MIT
    in my engineering training
  • 1:22 - 1:24
    and joined a student project
    building space robots.
  • 1:25 - 1:27
    And everything was going as I planned,
  • 1:28 - 1:32
    except I was confused
    about something important.
  • 1:34 - 1:37
    Now, my confusion arose
    in my summer breaks.
  • 1:37 - 1:40
    I traveled to a school in Kenya,
  • 1:41 - 1:46
    and there I volunteered
    with girls ages five to 17,
  • 1:46 - 1:50
    giving them lessons in English
    and math and science.
  • 1:51 - 1:54
    And they taught me songs in Swahili.
  • 1:55 - 1:59
    And mostly, I just spent time
    getting to know the girls,
  • 1:59 - 2:00
    enjoying their presence.
  • 2:01 - 2:05
    And I saw that these girls
    and the leaders in their community,
  • 2:05 - 2:08
    they were overcoming important barriers
  • 2:08 - 2:12
    to allow these girls to have
    the best possible chances in life.
  • 2:13 - 2:16
    And I wanted to join that team.
  • 2:17 - 2:20
    I wanted to be part of a team
    that would help break down barriers
  • 2:20 - 2:23
    and improve the lives
    of girls around the world.
  • 2:23 - 2:26
    But I was worried that studying
    aerospace engineering
  • 2:26 - 2:27
    wasn't the most useful.
  • 2:27 - 2:30
    I was worried this team in Kenya
    couldn't use the technology
  • 2:30 - 2:32
    I was learning about space.
  • 2:33 - 2:36
    But thankfully, I still learned
    that I was wrong.
  • 2:37 - 2:40
    I came back and interned at NASA again,
  • 2:40 - 2:41
    and this time,
  • 2:41 - 2:43
    a mentor taught me
  • 2:43 - 2:49
    that countries like Kenya had been using
    space technology for decades
  • 2:49 - 2:52
    to improve the lives
    in their own countries.
  • 2:52 - 2:55
    And then I knew that I could have
    a career in space
  • 2:55 - 2:57
    and in development.
  • 2:58 - 2:59
    This idea is not new.
  • 3:00 - 3:04
    In fact, in 1967, the nations
    of the world came together
  • 3:04 - 3:07
    to write the Outer Space Treaty.
  • 3:08 - 3:10
    This treaty made a bold statement,
  • 3:10 - 3:14
    saying, "The exploration
    and use of outer space
  • 3:14 - 3:18
    should be carried on
    for the benefit of all peoples,
  • 3:19 - 3:23
    irrespective of their level
    of economic or scientific development."
  • 3:25 - 3:27
    We have not truly lived up to this ideal,
  • 3:27 - 3:31
    although people have worked
    for decades to make this a reality.
  • 3:32 - 3:35
    Forces such as colonialism and racism
  • 3:36 - 3:38
    and gender inequality
  • 3:38 - 3:42
    have actually excluded many people
    from the benefits of space
  • 3:43 - 3:46
    and caused us to believe
    that space is for the few
  • 3:46 - 3:49
    or the rich or elite.
  • 3:50 - 3:52
    But we cannot afford this attitude,
  • 3:52 - 3:55
    because the world is engaged
    in a vital mission
  • 3:55 - 3:57
    to improve life for everyone.
  • 3:58 - 4:04
    Our road map for this mission comes
    from the 17 Sustainable Development Goals
  • 4:04 - 4:05
    of the United Nations.
  • 4:06 - 4:09
    All the member states
    of the United Nations have agreed
  • 4:09 - 4:12
    that these are priorities
    between now and 2030.
  • 4:13 - 4:18
    These goals give us our key moments
    and opportunities of our time --
  • 4:18 - 4:21
    opportunities to end extreme poverty,
  • 4:21 - 4:26
    to insure that everyone has access
    to food and clean water.
  • 4:28 - 4:31
    We must pursue these goals
    as a global community.
  • 4:32 - 4:36
    And technology from space
    supports sustainable development.
  • 4:37 - 4:40
    In fact, there are six space services
  • 4:40 - 4:44
    that can help us pursue
    the Sustainable Development Goals.
  • 4:45 - 4:48
    Over the next few minutes,
    let's explore these six services,
  • 4:48 - 4:52
    and see examples of just a few
    of the goals they help support.
  • 4:52 - 4:53
    You ready?
  • 4:53 - 4:54
    OK.
  • 4:54 - 4:58
    Communication satellites provide access
    to phone and internet service
  • 4:59 - 5:00
    to almost any location on Earth.
  • 5:01 - 5:04
    This is particularly important
    during times of disaster recovery.
  • 5:05 - 5:08
    When Typhoon Haiyan
    struck the Philippines,
  • 5:08 - 5:11
    the local communication networks
    needed to be repaired,
  • 5:11 - 5:14
    and teams brought in inflatable
    communication antennas
  • 5:14 - 5:16
    that could link to satellites.
  • 5:16 - 5:19
    This was useful during the time
    of repair and recovery.
  • 5:19 - 5:23
    Positioning satellites
    tell us where we are
  • 5:23 - 5:25
    by telling us where they are.
  • 5:26 - 5:30
    Scientists can use this technology
    to track endangered wildlife.
  • 5:31 - 5:33
    This turtle has been fitted with a system
  • 5:33 - 5:38
    that allows it to receive location
    information from positioning satellites,
  • 5:38 - 5:40
    and they send the location
    information to scientists
  • 5:40 - 5:42
    via communication satellites.
  • 5:43 - 5:46
    Scientists can use this knowledge
    to then make better policies
  • 5:46 - 5:49
    and help determine
    how to keep these animals alive.
  • 5:50 - 5:53
    Earth observation satellites.
  • 5:53 - 5:56
    They tell us what's going on
    in our environment.
  • 5:56 - 5:59
    Right now, there are about 150 satellites
  • 5:59 - 6:02
    operated by over 60 government agencies,
  • 6:02 - 6:04
    and these are just
    those observing the Earth.
  • 6:04 - 6:07
    And meanwhile, companies
    are adding to this list.
  • 6:07 - 6:11
    Most of the governments provide the data
    from the satellites for free online.
  • 6:11 - 6:14
    Some of these satellites
    provide images like this,
  • 6:14 - 6:17
    that show what you would see
    from a camera.
  • 6:17 - 6:20
    This is an image showing
    agricultural land in Kansas.
  • 6:21 - 6:24
    However, the majority
    of the Earth observation satellites
  • 6:24 - 6:26
    don't take pictures at all.
  • 6:26 - 6:27
    They take measurements.
  • 6:27 - 6:31
    And they combine these measurements
    with complex computer models
  • 6:31 - 6:34
    and make beautiful,
    global visualizations such as this one,
  • 6:34 - 6:36
    showing the ocean currents
  • 6:36 - 6:38
    and the temperature
    of the ocean, globally.
  • 6:39 - 6:45
    Or we can look at the salt and smoke
    and dust in the atmosphere,
  • 6:48 - 6:50
    or the rainfall and snowfall, globally,
  • 6:53 - 6:58
    as well as the annual cycle of vegetation
    on land and in the ocean.
  • 7:00 - 7:04
    Now, scientists can take this information
    about the rainfall and the vegetation
  • 7:04 - 7:06
    and use it to understand
  • 7:06 - 7:10
    what areas on Earth are in danger
    of a famine or a drought
  • 7:10 - 7:12
    and provide that information
    to aid organizations
  • 7:12 - 7:16
    so they can be prepared with food aid
    before the hunger becomes severe.
  • 7:17 - 7:22
    In space, we have an orbiting laboratory
    on the International Space Station.
  • 7:23 - 7:26
    The vehicle and everything inside
    are in a form of free fall
  • 7:26 - 7:27
    around the Earth,
  • 7:27 - 7:29
    and they don't experience
    the effect of gravity.
  • 7:30 - 7:32
    And because of this,
    we call it "microgravity."
  • 7:33 - 7:36
    When astronauts are
    in the microgravity environment,
  • 7:36 - 7:39
    their bodies react
    as if they're aging rapidly.
  • 7:40 - 7:42
    Their bones and muscles weaken,
  • 7:42 - 7:46
    and their cardiovascular system
    and their immune system change.
  • 7:47 - 7:50
    As scientists study how to keep
    astronauts healthy in space,
  • 7:50 - 7:54
    we can take the exercises and techniques
    we use for astronauts
  • 7:54 - 7:56
    and transfer them to people on Earth
  • 7:56 - 7:57
    to improve our health here.
  • 7:57 - 8:01
    Often, as we develop technology
    for astronauts and exploration
  • 8:01 - 8:02
    or for spacecraft,
  • 8:02 - 8:06
    we can also transfer those inventions
    to improve life on Earth.
  • 8:06 - 8:07
    Here's one of my favorites.
  • 8:07 - 8:09
    It's a water filtration system,
  • 8:09 - 8:12
    and a key component of it
    is based on the technology
  • 8:12 - 8:14
    to filter wastewater on the space station.
  • 8:14 - 8:16
    It's now being used around the world.
  • 8:17 - 8:20
    Space is also an infinite source
    of inspiration,
  • 8:20 - 8:21
    through education,
  • 8:21 - 8:23
    through research and astronomy
  • 8:23 - 8:26
    and that age-old experience of stargazing.
  • 8:27 - 8:30
    Now, countries around the world
    are engaging in advancing
  • 8:30 - 8:31
    their own development
  • 8:31 - 8:35
    by increasing their local knowledge
    of engineering and science and space.
  • 8:36 - 8:40
    Let's meet some of the world's
    newest satellite engineers.
  • 8:40 - 8:43
    This is Elyka Abello, from Venezuela.
  • 8:44 - 8:47
    Elyka is training as a satellite engineer
  • 8:47 - 8:50
    as part of her national
    satellite program in Venezuela.
  • 8:51 - 8:53
    She has designed a software tool
  • 8:53 - 8:56
    that allows her team to better design
    the power systems for engineering.
  • 8:58 - 9:01
    This is Adel Castillo-Duran,
  • 9:01 - 9:02
    from the Philippines.
  • 9:02 - 9:05
    Adel is both a meteorologist
    and a satellite engineer,
  • 9:06 - 9:09
    and she uses data from satellites
    in her weather forecasting.
  • 9:11 - 9:12
    And finally, meet Hala.
  • 9:13 - 9:14
    Hala is from the Sudan,
  • 9:14 - 9:18
    and as she was studying electrical
    engineering as an undergraduate
  • 9:18 - 9:19
    in Khartoum,
  • 9:19 - 9:22
    she and several students decided
    to build their own satellite.
  • 9:22 - 9:26
    And later, Hala earned a scholarship
    to study satellite engineering
  • 9:26 - 9:28
    at the graduate level.
  • 9:29 - 9:31
    These stories that I've shared with you
  • 9:31 - 9:36
    all illustrate that space truly is useful
    for sustainable development
  • 9:36 - 9:37
    for the benefit of all peoples.
  • 9:38 - 9:40
    But we have more work to do,
  • 9:40 - 9:44
    because there are still barriers
    that exclude people from space
  • 9:44 - 9:46
    and limit the impact of this technology.
  • 9:47 - 9:51
    For many people,
    Earth observation data is complex.
  • 9:52 - 9:54
    And satellite communication
    services are too expensive.
  • 9:55 - 9:58
    And microgravity research
    just appears to be inaccessible.
  • 10:00 - 10:04
    This is what motivates my work
    as a professor at MIT's Media Lab.
  • 10:05 - 10:10
    I've recently founded a new research group
    called Space Enabled.
  • 10:11 - 10:15
    We are working to tear down these barriers
    that limit the benefits of space.
  • 10:16 - 10:18
    And we're also going to develop
    the future applications
  • 10:18 - 10:22
    that will continue to contribute
    to sustainable development.
  • 10:23 - 10:24
    We'll keep on this work
  • 10:24 - 10:28
    until we can truly say that space
    is for the benefit of all peoples,
  • 10:29 - 10:32
    and we are all space enabled.
  • 10:33 - 10:34
    Thank you.
  • 10:34 - 10:37
    (Applause)
