During four centuries of earthbound observations, astronomers seeking detail on the Red Planet found plenty - much of it real, some of it imagined.
Tattooed with craters and gullies, this dusty planet holds secrets of a wild youth. Scientists are studying the scars to piece together Mar's active past, which may not have ended as long ago as we think.
With a single goal - to test the hypothesis that Mars once had an earthlike geology, climate, and maybe even biology - the Mars Exploration Rovers are set to rove NASA into a new era of planetary exploration.
