00:00:01,266 --> 00:00:05,200
Is Mars habitable? Well, maybe.\h\h

2
00:00:08,815 --> 00:00:10,497
We Asked a NASA Scientist

3
00:00:10,880 --> 00:00:18,000
The question is, "Is it habitable and for whom?"\h
Mars is hundreds of degrees colder than Earth,\h\h

4
00:00:18,000 --> 00:00:23,920
it has a hundred times less atmosphere and that\h
atmosphere has hardly any oxygen. But there may\h\h

5
00:00:23,920 --> 00:00:29,360
be other forms of life that could have evolved\h
that aren't very much like us but are very much\h\h

6
00:00:29,360 --> 00:00:35,680
like the early forms of life that evolved on\h
Earth. Mars has evidence of being warmer in the\h\h

7
00:00:35,680 --> 00:00:41,440
past and of having stable liquid surface water\h
for potentially hundreds of thousands of years.\h\h

8
00:00:42,000 --> 00:00:48,560
So it's possible that in Mars' past there\h
was a time where life could have evolved\h\h

9
00:00:48,560 --> 00:00:52,800
in that particular environment. We have\h
been trying to answer that question\h\h
