These are only a few of the facts we have learned about Mars since we began to explore it. But these barely scratch the surface of the discoveries we have made about Mars.

This is probably the reason why many astronomers and astrophysicists consider Mars as a potential habitat for humans. You may read about the other six discoveries here.
