Life On Mars? What do you think?

 

Travelers of the Future, Beware! Mars is no place for the faint-hearted. Arid, rocky, cold and apparently lifeless, the Red Planet offers few hospitalities. Fans of extreme sports can rejoice, however, for the Red Planet will challenge even the hardiest souls among us. Home to the largest volcano in the solar system, the deepest canyon and crazy weather and temperature patterns, Mars looms as the ultimate lonely planet destination.

Spirit and Opportunity are two space robots assigned to Mars.  They are on a mission to explore the planet and send home pictures and vital information.  So far they have discovered that there may be signs of water on this planet and a sulfur rich ground.
