00:00:02.200 --> 00:00:04.133
In order for NASA to map and explore

3
00:00:04.133 --> 00:00:06.566
the region around the lunar South Pole,

4
00:00:06.566 --> 00:00:08.566
we need to precisely define a system of

5
00:00:08.566 --> 00:00:10.833
latitude and longitude on the Moon,

6
00:00:10.833 --> 00:00:14.300
including the exact location of the South Pole itself.

7
00:00:15.666 --> 00:00:16.733
In the coordinate system

8
00:00:16.733 --> 00:00:19.566
adopted by the Lunar Reconnaissance Orbiter mission,

9
00:00:19.566 --> 00:00:21.266
the South Pole is here,

10
00:00:21.266 --> 00:00:23.766
on the rugged rim of Shackleton crater.

11
00:00:28.033 --> 00:00:30.100
If you stood on this treacherous spot,

12
00:00:30.100 --> 00:00:32.166
you’d see the sunlit rim of the crater,

13
00:00:32.166 --> 00:00:34.466
encircling a permanently shadowed abyss

14
00:00:34.466 --> 00:00:36.400
that’s two and a half miles deep,

15
00:00:36.400 --> 00:00:38.600
over twice that of the Grand Canyon,

16
00:00:38.600 --> 00:00:41.600
covering an area over 130 square miles.

17
00:00:43.700 --> 00:00:45.866
As we return to the lunar surface,

18
00:00:45.866 --> 00:00:47.166
three dimensional maps like this

19
00:00:47.166 --> 00:00:49.933
will help guide astronauts to safe landing sites

20
00:00:49.933 --> 00:00:53.500
in the challenging landscape of the Moon’s South Pole.
