3
00:00:06,706 --> 00:00:07,707
I STUDY THE MOON,

4
00:00:07,707 --> 00:00:08,908
AND THIS IS "ASK NASA."

5
00:00:15,048 --> 00:00:16,549
OUR FIRST QUESTION IS,

6
00:00:16,549 --> 00:00:18,084
"WHAT IS THE MOON MADE OF?"

7
00:00:18,084 --> 00:00:18,818
THE MOON IS MADE OF

8
00:00:18,818 --> 00:00:19,786
MOST OF THE SAME STUFF

9
00:00:19,786 --> 00:00:20,987
THAT THE EARTH IS MADE OF.

10
00:00:20,987 --> 00:00:22,188
THE MOON FORMED,

11
00:00:22,188 --> 00:00:23,256
UH, MANY YEARS AGO

12
00:00:23,256 --> 00:00:24,190
WHEN THE EARTH WAS STILL,

13
00:00:24,190 --> 00:00:25,458
SORT OF, MOLTEN,

14
00:00:25,458 --> 00:00:26,459
AND IT WAS HIT BY SOMETHING

15
00:00:26,459 --> 00:00:28,294
ABOUT THE SIZE OF MARS,

16
00:00:28,294 --> 00:00:29,129
AND IT KICKED OFF A LOT OF

17
00:00:29,129 --> 00:00:30,330
MATERIAL AND THAT MATERIAL

18
00:00:30,330 --> 00:00:31,564
CAME TO FORM THE MOON.

19
00:00:31,564 --> 00:00:32,165
AND SO, WE'RE MADE OF

20
00:00:32,165 --> 00:00:33,533
THE SAME STUFF.

21
00:00:35,168 --> 00:00:36,903
"CAN WE LIVE ON THE MOON?"

22
00:00:36,903 --> 00:00:37,804
THAT'S A GREAT QUESTION.

23
00:00:37,804 --> 00:00:38,705
WELL, THE MOON DOESN'T HAVE

24
00:00:38,705 --> 00:00:39,739
AN ATMOSPHERE, SO WE'LL-

25
00:00:39,739 --> 00:00:41,040
WE'LL NEED SOME TECHNOLOGY

26
00:00:41,040 --> 00:00:42,542
IN ORDER TO SURVIVE THERE.

27
00:00:42,542 --> 00:00:43,410
BUT THERE'S NO REASON WHY

28
00:00:43,410 --> 00:00:44,144
WE CAN'T BRING

38
00:00:55,588 --> 00:00:56,556

CAN'T REACH DOWN IN THERE,

AND IT'S SO COLD

46
00:01:05,465 --> 00:01:06,499
THAT ONCE WATER GETS THERE,

47
00:01:06,499 --> 00:01:07,901

52
00:01:12,105 --> 00:01:13,039
AND FIND OUT

53
00:01:13,039 --> 00:01:13,873
JUST HOW MUCH WATER IS THERE.

00:01:13,873 --> 00:01:14,774
