The world's first crowdsourced space traffic monitoring system
-
0:01 - 0:04I am an astrodynamicist --
-
0:04 - 0:07you know, like that guy Rich Purnell
in the movie "The Martian." -
0:08 - 0:14And it's my job to study and predict
motion of objects in space. -
0:15 - 0:21Currently we track about one percent
of hazardous objects on orbit -- -
0:22 - 0:25hazardous to services like location,
-
0:25 - 0:27agriculture, banking,
-
0:27 - 0:29television and communications,
-
0:29 - 0:31and soon -- very soon --
-
0:31 - 0:33even the internet itself.
-
0:34 - 0:40Now these services are not protected
from, roughly, half a million objects -
0:40 - 0:42the size of a speck of paint
-
0:43 - 0:45all the way to a school bus in size.
-
0:46 - 0:48A speck of paint,
-
0:48 - 0:51traveling at the right speed,
-
0:51 - 0:53impacting one of these objects,
-
0:53 - 0:55could render it absolutely useless.
-
0:56 - 1:00But we can't track things
as small as a speck of paint. -
1:01 - 1:05We can only track things
as small as say, a smartphone. -
1:06 - 1:10So of this half million objects
that we should be concerned about, -
1:10 - 1:15we can only track
about 26,000 of these objects. -
1:15 - 1:20And of these 26,000,
only 2,000 actually work. -
1:22 - 1:23Everything else
-
1:24 - 1:25is garbage.
-
1:26 - 1:28That's a lot of garbage.
-
1:28 - 1:30To make things a little bit worse,
-
1:31 - 1:35most of what we launch into orbit
never comes back. -
1:37 - 1:40We send the satellite in orbit,
-
1:40 - 1:43it stops working, it runs out of fuel,
-
1:43 - 1:46and we send something else up ...
-
1:46 - 1:48and then we send up something else ...
-
1:48 - 1:50and then something else.
-
1:50 - 1:51And every once in a while,
-
1:51 - 1:54two of these things
will collide with each other -
1:54 - 1:56or one of these things will explode,
-
1:56 - 1:57or even worse,
-
1:57 - 2:00somebody might just happen to destroy
one of their satellites on orbit, -
2:02 - 2:05and this generates many, many more pieces,
-
2:05 - 2:08most of which also never come back.
-
2:09 - 2:13Now these things are not
just randomly scattered in orbit. -
2:14 - 2:17It turns out that given
the curvature of space-time, -
2:17 - 2:19there are ideal locations
-
2:19 - 2:21where we put some of these satellites --
-
2:21 - 2:24think of these as space highways.
-
2:25 - 2:27Very much like highways on earth,
-
2:27 - 2:32these space highways can only take up
a maximum capacity of traffic -
2:32 - 2:36to sustain space-safe operations.
-
2:37 - 2:39Unlike highways on earth,
-
2:39 - 2:42there are actually no space traffic rules.
-
2:42 - 2:44None whatsoever, OK?
-
2:46 - 2:47Wow.
-
2:48 - 2:50What could possibly go wrong with that?
-
2:50 - 2:52(Laughter)
-
2:52 - 2:55Now, what would be really nice
-
2:55 - 2:58is if we had something
like a space traffic map, -
2:58 - 3:02like a Waze for space that I could look up
-
3:02 - 3:04and see what the current
traffic conditions are in space, -
3:04 - 3:06maybe even predict these.
-
3:06 - 3:08The problem with that, however,
-
3:08 - 3:11is that ask five different people,
-
3:12 - 3:14"What's going on in orbit?
-
3:14 - 3:15Where are things going?"
-
3:15 - 3:18and you're probably going to get
10 different answers. -
3:18 - 3:19Why is that?
-
3:19 - 3:24It's because information about things
on orbit is not commonly shared either. -
3:25 - 3:28So what if we had a globally accessible,
-
3:28 - 3:31open and transparent
space traffic information system -
3:31 - 3:34that can inform the public
of where everything is located -
3:34 - 3:37to try to keep space safe and sustainable?
-
3:37 - 3:41And what if the system could be used
-
3:41 - 3:44to form evidence-based
norms of behavior -- -
3:44 - 3:45these space traffic rules?
-
3:46 - 3:48So I developed ASTRIAGraph,
-
3:48 - 3:52the world's first crowdsourced,
space traffic monitoring system -
3:52 - 3:54at the University of Texas at Austin.
-
3:55 - 4:00ASTRIAGraph combines multiple sources
of information from around the globe -- -
4:00 - 4:02government, industry and academia --
-
4:02 - 4:06and represents this in a common framework
that anybody can access today. -
4:07 - 4:12Here, you can see 26,000 objects
orbiting the earth, -
4:12 - 4:14multiple opinions,
-
4:14 - 4:16and it gets updated in near real time.
-
4:16 - 4:20But back to my problem
of space traffic map: -
4:20 - 4:23What if you only had information
from the US government? -
4:24 - 4:27Well, in that case, that's what
your space traffic map would look like. -
4:28 - 4:30But what do the Russians think?
-
4:33 - 4:35That looks significantly different.
-
4:36 - 4:38Who's right? Who's wrong?
-
4:38 - 4:39What should I believe?
-
4:39 - 4:41What could I trust?
-
4:41 - 4:42This is part of the issue.
-
4:44 - 4:51In the absence of this framework
to monitor space-actor behavior, -
4:51 - 4:54to monitor activity in space --
-
4:54 - 4:55where these objects are located --
-
4:55 - 4:58to reconcile these inconsistencies
-
4:58 - 5:01and make this knowledge commonplace,
-
5:01 - 5:05we actually risk losing the ability
-
5:06 - 5:09to use space for humanity's benefit.
-
5:10 - 5:12Thank you very much.
-
5:12 - 5:16(Applause and cheers)
- Title:
- The world's first crowdsourced space traffic monitoring system
- Speaker:
- Moriba Jah
- Description:
-
"Most of what we send into outer space never comes back," says astrodynamicist and TED Fellow Moriba Jah. In this forward-thinking talk, Jah describes the space highways orbiting earth and how they're mostly populated by space junk. Learn more about his quest to develop and scale the world's first crowdsourced space traffic monitoring system -- and how it could help solve the debris problem in near-earth space.
