00:00:00.600 --> 00:00:04.371
We learned a lot from the Apollo samples,
but we still have a lot

2
00:00:04.371 --> 00:00:06.306
left to learn about the Moon.

3
00:00:06.306 --> 00:00:10.110
The Apollo missions visited
only a pretty narrow swath of the Moon,

4
00:00:10.410 --> 00:00:13.413
all the missions were concentrated
near the near side equator.

5
00:00:13.613 --> 00:00:15.815
Really interesting
and really critical insights

6
00:00:15.815 --> 00:00:17.484
were unlocked with the Apollo samples,

7
00:00:17.484 --> 00:00:20.520
but we have so many questions
still to answer about the Moon

8
00:00:20.520 --> 00:00:22.522
and the evolution of the Moon.

00:00:23.023 --> 00:00:29.896
[Dramatic music]

10
00:00:29.896 --> 00:00:31.965
Launch commentator:
And liftoff of Artemis One!

11
00:00:31.965 --> 00:00:35.735
We rise together,
back to the Moon and beyond.

12
00:00:37.337 --> 00:00:38.838
NASA's Artemis missions

13
00:00:38.838 --> 00:00:42.208
are NASA's plan to send people
to the surface of the Moon.

14
00:00:42.442 --> 00:00:46.880
We'll be sending people and roving
assets and scientific equipment

15
00:00:46.980 --> 00:00:50.083
to, among other things, answer a lot of
really compelling science questions.

16
00:00:50.583 --> 00:00:52.685
Scientists have a lot to learn
about the Moon.

17
00:00:52.685 --> 00:00:55.155
It's our nearest celestial neighbor
here to Earth.

18
00:00:55.155 --> 00:00:57.724
So what the Moon has experienced,
we've experienced,

19
00:00:57.724 --> 00:00:59.626
except here on Earth,
we have things like plate

20
00:00:59.626 --> 00:01:03.830
tectonics, oceans, forests, people
that erase the rock record.

21
00:01:03.963 --> 00:01:07.267
Whereas on the Moon, that whole record
of our planet's history, of the Moon's

22
00:01:07.267 --> 00:01:10.370
history is just kind of waiting there
at the surface for us to explore.

23
00:01:10.804 --> 00:01:13.773
The South Pole, which is where Artemis
missions are going to target,

24
00:01:13.773 --> 00:01:16.776
is specifically interesting
for a couple key reasons.

25
00:01:16.910 --> 00:01:17.911
We think there are volatiles

26
00:01:17.911 --> 00:01:20.747
at the South Pole of the Moon
that are not present near the equator.

27
00:01:20.747 --> 00:01:23.983
Things like water and water ice
that are trapped in the lunar regolith,

28
00:01:23.983 --> 00:01:28.288
which basically just means lunar soil,
that can easily become untrapped from that

29
00:01:28.288 --> 00:01:31.691
lunar regolith and scientists can scoop up
and study for return to Earth.

30
00:01:32.425 --> 00:01:35.495
The lunar South Pole is a really
exciting scientific target,

31
00:01:35.495 --> 00:01:38.465
and it also comes with some
challenges for operating.

32
00:01:38.465 --> 00:01:42.469
For example, the lighting environment
will change drastically within the course

33
00:01:42.469 --> 00:01:46.139
of one mission and even over
sometimes the course of one spacewalk.

34
00:01:46.306 --> 00:01:50.076
So preparing the crew members,
preparing the hardware that we're sending

35
00:01:50.076 --> 00:01:53.713
to the Moon, and preparing the mission
control teams is really, really important.

36
00:01:54.147 --> 00:01:56.516
The South Pole-Aitken Basin
is particularly exciting.

37
00:01:56.516 --> 00:02:00.320
We think it's one of the oldest and
largest impact basins in the solar system,

38
00:02:00.420 --> 00:02:04.090
and if we can get the right rock
from the South Pole-Aitken Basin

39
00:02:04.090 --> 00:02:07.594
and bring it back to our labs
here on Earth, we can use that sample

40
00:02:07.660 --> 00:02:11.197
to constrain the entire evolution
of our solar system and really understand

41
00:02:11.197 --> 00:02:15.768
the timing of how the Moon and our planet
and the entire solar system evolved.

42
00:02:15.768 --> 00:02:21.574
