The lack of a magnetosphere and extremely thin atmosphere of Mars are a greater challenge: the planet has little heat transfer across its surface, poor insulation against bombardment and the solar wind, and insufficient atmospheric pressure to retain water in a liquid form (water instead sublimates to a gaseous state). Mars is also nearly, or perhaps totally, geologically dead; the end of volcanic activity has stopped the recycling of chemicals and minerals between the surface and interior of the planet.

May be e can get nature miner rexource in future.
Scientists have been poring over data from Mars orbiters. They have searched for sites that are most likely to help us understand Mars' ability to support life in the past. In September 2008, the scientists narrowed their favorites to seven.
Meanwhile, engineers have been studying the safety of each landing site. They scoped out dangerous rocks and hills to understand how well the rover can drive over each terrain. Then, they produced their own "party's" picks.

Two moons. One named Phobos. The other named Deimos.
