1
00:00:00,255 --> 00:00:01,869
Will an asteroid ever hit Earth?

2
00:00:01,869 --> 00:00:03,071
Do aliens exist?

3
00:00:03,071 --> 00:00:06,380
Is there water on Mars? Where did our Moon come\h
from? Are there rainbows on Mars?

4
00:00:06,380 --> 00:00:10,179
Does\hNASA know about all the asteroids? Is NASA aware\h
of any Earth-threatening asteroids? Did Mars ever\hlook like Earth? Could microbes survive a trip to\hMars? Is Mars habitable?

5
00:00:14,236 --> 00:00:15,134
We asked a NASA expert.

6
00:00:15,456 --> 00:00:17,152
That's a really interesting question.

7
00:00:17,152 --> 00:00:18,408
Well,\hyes.

8
00:00:18,408 --> 00:00:19,501
Yes, of course.

9
00:00:19,501 --> 00:00:20,001
Yes.

10
00:00:20,001 --> 00:00:20,701
Actually.

11
00:00:20,701 --> 00:00:21,667
Well, maybe.

12
00:00:22,692 --> 00:00:22,192
No.

13
00:00:22,692 --> 00:00:23,334
It is possible.

14
00:00:24,334 --> 00:00:23,834
Yes.

15
00:00:24,334 --> 00:00:25,387
The answer is yes.

16
00:00:25,387 --> 00:00:27,026
In fact, we're quite confident.

17
00:00:27,026 --> 00:00:27,811
It is proven.

18
00:00:27,811 --> 00:00:29,744
There have\hbeen several theories.

19
00:00:29,744 --> 00:00:32,356
One that we have been\htrying to understand.

20
00:00:32,356 --> 00:00:34,033
The question of, "Are we\halone?"

21
00:00:34,033 --> 00:00:37,008
The universe is a pretty big place. We've only begun to look.

22
00:00:37,008 --> 00:00:38,650
We haven't really observed it.

23
00:00:38,650 --> 00:00:39,626
We see evidence.

24
00:00:39,626 --> 00:00:41,040
Where do we find those worlds?

25
00:00:41,040 --> 00:00:43,212
That's why it's so fascinating.

26
00:00:43,212 --> 00:00:44,415
So stay tuned.

27
00:00:44,415 --> 00:00:46,123
To\hkeep the long story short.

28
00:00:46,123 --> 00:00:49,227
We have been trying to\hanswer that question definitively.

29
00:00:49,227 --> 00:00:51,714
And explore and\hfigure out

30
00:00:51,714 --> 00:00:53,145
a quest for that answer.

31
00:00:53,145 --> 00:00:55,852
And as of yet,\hthe the answer is still, definitely maybe.

32
00:00:56,782 --> 00:00:58,521
We asked a NASA scientist. We asked a NASA technologist.

33
00:00:58,521 --> 00:01:00,131
So keep your eyes peeled and keep looking up.
