NASA Connect Segment explaining why we are exploring Mars. It also reveals tools and techniques used to explore Mars.
Why are we exploring Mars?
00:00:00
What tools and techniques does NASA use to explore Mars?
00:00:07
NASA is committed to exploring Mars.
00:00:11
In fact, they will be sending a robot to Mars once every two years for the next decade.
00:00:14
Mars is very interesting because not only is it right next door,
00:00:19
but it's the planet with the most hospitable climate in the solar system.
00:00:23
So hospitable, in fact, that it may once have been the home to primitive bacteria-like life.
00:00:27
These pictures show dried up river and lake beds,
00:00:34
and so we know that liquid water flowed on the surface billions of years ago.
00:00:37
So where has all the water gone?
00:00:41
Has it just floated off into space?
00:00:43
Scientists think that a lot of the water may be chemically bound to the soil,
00:00:45
or underneath the surface in either liquid or ice form.
00:00:49
Understanding where the water currently is can help us understand the history of water on Mars,
00:00:53
which is important in determining if there is or ever was life on that planet.
