Why Mars?
Mars is the fourth planet from the Sun, and the seventh largest. It’s the only planet we know of inhabited entirely by robots.
- Mars is one of the most explored bodies in our solar system, and it's the only planet where we've sent rovers to explore the alien landscape. NASA missions have found lots of evidence that Mars was much wetter and warmer, with a thicker atmosphere, billions of years ago.
- Mars is no place for the faint-hearted. It’s dry, rocky, and bitter cold. There are even ice caps called the Martian polar ice caps.
- Mars remains our horizon goal for human exploration because it is one of the only other places we know in the solar system where life may have existed. What we learn about the Red Planet will tell us more about our Earth’s past and future, and may help answer whether life exists beyond our home planet.
