00:00:13.347 --> 00:00:14.715
- These little CubeSats

00:00:14.715 --> 00:00:17.084
are revolutionizing
satellite science.

00:00:17.084 --> 00:00:18.886
But do you think something
this small

00:00:18.886 --> 00:00:21.822
is big enough to help NASA
gather science data?

00:00:21.822 --> 00:00:23.156
Let's find out.

00:00:23.156 --> 00:00:25.425
- We currently have an Earth
orbiting satellite

00:00:25.425 --> 00:00:28.362
called RAVAN; it's been
up there for about a year.

00:00:28.362 --> 00:00:31.431
RAVAN stands for
Radiometer Assessment

00:00:31.431 --> 00:00:34.168
of Vertically Aligned
Carbon Nanotubes.

00:00:34.168 --> 00:00:38.138
So RAVAN measures the Earth's
radiation imbalance.

00:00:38.138 --> 00:00:41.275
So how much energy is getting
absorbed by the Earth

00:00:41.275 --> 00:00:43.443
and how much
gets reflected back.

00:00:43.443 --> 00:00:46.613
That's a big question that's
an important parameter

00:00:46.613 --> 00:00:48.715
for climate science.

00:00:48.715 --> 00:00:50.450
RAVAN serves as a pathfinder

00:00:50.450 --> 00:00:51.752
for Constellation.

00:00:51.752 --> 00:00:54.221
The idea is to put
a constellation

00:00:54.221 --> 00:00:56.823
of these small satellites
around the globe

00:00:56.823 --> 00:00:59.193
so you can get simultaneous
measurements

00:00:59.193 --> 00:01:02.596
of the radiation reflecting
back out into space.

00:01:02.596 --> 00:01:05.699
The future of CubeSats
is very bright.

00:01:05.699 --> 00:01:08.068
The more that we demonstrate
technologies,

00:01:08.068 --> 00:01:10.537
the more we can incorporate
into science

00:01:10.537 --> 00:01:12.973
and the more CubeSats
can go up

00:01:12.973 --> 00:01:14.575
and take simultaneous data.

00:01:14.575 --> 00:01:17.711
For example, you could have
simultaneous global measurements

00:01:17.711 --> 00:01:20.681
around the Earth, measuring
things that you could never

00:01:20.681 --> 00:01:22.282
have imagined before.

00:01:22.282 --> 00:01:25.118
With the Swarm of CubeSats,
we could have rapid refresh

00:01:25.118 --> 00:01:27.221
over natural disasters,

00:01:27.221 --> 00:01:29.890
such as cyclones
or hurricanes.

00:01:29.890 --> 00:01:32.392
The advantage of swarming,
over typical satellite,

00:01:32.392 --> 00:01:34.962
is that you don't have to send
commands up and down

00:01:34.962 --> 00:01:37.598
because they already know
what to do next.

00:01:37.598 --> 00:01:39.166
- CubeSats are changing
the way

00:01:39.166 --> 00:01:40.701
we are collecting information

00:01:40.701 --> 00:01:43.370
and allowing more and more
people access to space

00:01:43.370 --> 00:01:45.372
because they are less expensive.

00:01:45.372 --> 00:01:47.608
Kids like you and me
have opportunities

00:01:47.608 --> 00:01:51.011
to get involved by designing
and building our own CubeSats

00:01:51.011 --> 00:01:52.513
that could be launched
by NASA.

00:01:52.513 --> 00:01:53.981

00:01:53.981 --> 00:01:55.449
Check out this site and click on

00:01:55.449 --> 00:01:59.653
the NASA CubeSat
Launch Initiative, or CSLI.

00:01:59.653 --> 00:02:01.622
They might be small,
but CubeSats are providing

00:02:01.622 --> 00:02:03.857
answers to big questions.

00:02:03.857 --> 00:02:05.192
That's all for now.

00:02:05.192 --> 00:02:08.061
See you next time
on NASA eClips.
