[Energetic music] 
Hi, I'm Raquel Villanueva,

00:00:02.202 --> 00:00:04.838 align:center line:-1 position:50% size:30%
here at NASA's Jet
Propulsion Laboratory.

00:00:04.838 --> 00:00:08.342 align:center line:-1 position:50% size:38%
Now, it has been a dream of
scientists for generations

00:00:08.342 --> 00:00:11.778 align:center line:-1 position:50% size:34%
to bring back samples
from the surface of Mars.

00:00:11.778 --> 00:00:15.382 align:center line:-1 position:50% size:42%
Right now, the Mars 2020 rover
is laying the groundwork

00:00:15.382 --> 00:00:16.650 align:center line:-1 position:50% size:25%
for that to happen.

00:00:18.585 --> 00:00:21.688 align:center line:-1 position:50% size:39%
And, that's why I'm in the
In-Situ Instrument Laboratory

00:00:21.688 --> 00:00:23.290 align:center line:-1 position:50% size:30%
with Jessica Samuels.

00:00:23.290 --> 00:00:26.460 align:center line:-1 position:50% size:33%
And, she's here to tell us
what's going on here.

00:00:26.460 --> 00:00:29.630 align:center line:-1 position:50% size:42%
[Jessica Samuels] Well, we use
this facility to develop and

00:00:29.630 --> 00:00:32.666 align:center line:-1 position:50% size:46%
design our hardware and software
systems for our Mars missions.

00:00:32.666 --> 00:00:34.468 align:center line:-1 position:50% size:37%
[Raquel] And, how does the
sampling system work.

00:00:34.668 --> 00:00:38.338 align:center line:-1 position:50% size:42%
[Jessica] So, we have a drill on
the end of our robotic arm.

00:00:38.338 --> 00:00:41.642 align:center line:-1 position:50% size:36%
And, as we are drilling the
surface of Mars, we will be

00:00:41.642 --> 00:00:46.046 align:center line:-1 position:50% size:39%
collecting pieces of Mars into
the sample tube at that time.

00:00:46.046 --> 00:00:48.215 align:center line:-1 position:50% size:25%
We'll then transfer
that sample tube

00:00:48.215 --> 00:00:52.286 align:center line:-1 position:50% size:36%
into the inside of the rover
and then seal it for storage

00:00:52.286 --> 00:00:54.655 align:center line:-1 position:50% size:27%
as we continue to
explore the surface.

00:00:54.655 --> 00:00:57.090 align:center line:-1 position:50% size:31%
After we've collected a
diverse set of samples,

00:00:57.090 --> 00:00:59.626 align:center line:-1 position:50% size:28%
we will drop them off
onto the surface...

00:00:59.893 --> 00:01:00.427 align:center line:-1 position:50% size:20%
[Raquel] Yeah.

00:01:00.427 --> 00:01:01.228 align:center line:-1 position:50% size:26%
[Jessica]...and then
have them there

00:01:01.228 --> 00:01:04.831 align:center line:-1 position:50% size:34%
for a future sample return
mission to continue.

00:01:04.831 --> 00:01:06.700 align:center line:-1 position:50% size:42%
[Raquel] Well, I know you have
some tests to keep doing

00:01:06.700 --> 00:01:10.103 align:center line:-1 position:50% size:35%
and I'm actually gonna go
check out the next phase

00:01:10.103 --> 00:01:11.371 align:center line:-1 position:50% size:23%
at a different lab.

00:01:13.307 --> 00:01:15.976 align:center line:-1 position:50% size:37%
We're in a testing lab
affectionately known as the

00:01:15.976 --> 00:01:18.612 align:center line:-1 position:50% size:33%
"Sand Box" and I'm here
with Austin Nicholas.

00:01:18.612 --> 00:01:20.580 align:center line:-1 position:50% size:45%
Now, can you explain how we are

00:01:20.580 --> 00:01:22.516 align:center line:-1 position:50% size:28%
gonna bring back
samples from Mars?

00:01:22.516 --> 00:01:24.985 align:center line:-1 position:50% size:32%
[Austin Nicholas] So,
starting from after 2020

00:01:24.985 --> 00:01:26.954 align:center line:-1 position:50% size:27%
has deposited tubes
on the surface,

00:01:26.954 --> 00:01:28.388 align:center line:-1 position:50% size:26%
there are two more
missions to go in

00:01:28.388 --> 00:01:29.990 align:center line:-1 position:50% size:24%
bringing the tubes
back to Earth.

00:01:29.990 --> 00:01:31.591 align:center line:-1 position:50% size:38%
The first is a lander mission.

00:01:31.591 --> 00:01:33.493 align:center line:-1 position:50% size:42%
It carries three major elements:

00:01:33.493 --> 00:01:35.996 align:center line:-1 position:50% size:36%
a Sample Fetch Rover and
a Sample Transfer Arm

00:01:35.996 --> 00:01:37.497 align:center line:-1 position:50% size:28%
that lets you transfer
the samples from

00:01:37.497 --> 00:01:39.433 align:center line:-1 position:50% size:42%
the Fetch Rover into the rocket,

00:01:39.433 --> 00:01:41.702 align:center line:-1 position:50% size:33%
and a Mars Ascent
Vehicle which is a rocket

00:01:41.702 --> 00:01:44.237 align:center line:-1 position:50% size:32%
that brings the samples
from Mars into space.

00:01:44.237 --> 00:01:47.507 align:center line:-1 position:50% size:44%
Meanwhile, the orbiter has also
launched from Earth in 2026 and

00:01:47.507 --> 00:01:50.277 align:center line:-1 position:50% size:42%
is making its way towards Mars
and it'll be in position

00:01:50.277 --> 00:01:52.112 align:center line:-1 position:50% size:28%
by the time the
rocket's fully loaded.

00:01:52.112 --> 00:01:55.148 align:center line:-1 position:50% size:39%
The orbiter will then go to the
sample container that the

00:01:55.148 --> 00:01:57.551 align:center line:-1 position:50% size:30%
rocket's put into space
and then capture it,

00:01:57.551 --> 00:01:59.720 align:center line:-1 position:50% size:30%
ultimately bringing
them to Earth in 2031.

00:02:00.053 --> 00:02:01.488 align:center line:-1 position:50% size:29%
[Raquel] That sounds
complicated.

00:02:01.488 --> 00:02:02.389 align:center line:-1 position:50% size:33%
[Austin] It is complicated

00:02:02.389 --> 00:02:03.991 align:center line:-1 position:50% size:27%
but fortunately we're
not doing it alone.

00:02:03.991 --> 00:02:06.626 align:center line:-1 position:50% size:45%
So, we have a great partnership
with the European Space Agency

00:02:06.626 --> 00:02:08.962 align:center line:-1 position:50% size:45%
and they're providing some major
pieces of this mission.

00:02:08.962 --> 00:02:11.765 align:center line:-1 position:50% size:43%
Within NASA, we've actually got
a number of centers working on

00:02:11.765 --> 00:02:13.100 align:center line:-1 position:50% size:34%
all of the different pieces.

00:02:13.100 --> 00:02:15.135 align:center line:-1 position:50% size:39%
So, we're partnering with
Marshall Space Flight Center

00:02:15.135 --> 00:02:16.303 align:center line:-1 position:50% size:38%
for the Mars Ascent Vehicle,

00:02:16.303 --> 00:02:19.239 align:center line:-1 position:50% size:35%
Langley and Ames for the
Earth Entry Vehicle,

00:02:19.239 --> 00:02:21.408 align:center line:-1 position:50% size:29%
Glenn for the Sample
Fetch Rover wheels

00:02:21.408 --> 00:02:24.177 align:center line:-1 position:50% size:43%
and we're partnering with
Goddard for the orbiter payload.

00:02:24.177 --> 00:02:26.313 align:center line:-1 position:50% size:33%
And so there's really a...
it's a whole NASA effort

00:02:26.313 --> 00:02:27.848 align:center line:-1 position:50% size:45%
to get Mars Sample Return done.

00:02:27.848 --> 00:02:29.783 align:center line:-1 position:50% size:39%
[Raquel] Sounds like there is
a lot of work to be done,

00:02:29.783 --> 00:02:34.021 align:center line:-1 position:50% size:45%
but this all kicks off with the
launch of Mars 2020 this summer

00:02:34.021 --> 00:02:35.689 align:center line:-1 position:50% size:37%
in Cape Canaveral, Florida,

00:02:35.689 --> 00:02:36.990 align:center line:-1 position:50% size:25%
and there's lots
of excitement here

00:02:36.990 --> 00:02:39.159 align:center line:-1 position:50% size:22%
as we get ready
to make history.
