If you were a scientist studying Mars and sharing your progress with family and friends, perhaps you would send back digital postcards showing them where you've been. Earthlings have now received a record 200,000 such postcards from NASA?s two Mars rovers!

The images enable us to study changes on the red planet, such as subtle variations in color and texture shown here in a ring of rocks inside "Victoria Crater." The light-colored rocks are interesting because scientists think they may be the original surface before a meteor formed the crater and splattered debris onto it.
