The Surface of Gusev - Sol 872 (Approx. True Colors; credits: NASA/JPL-Caltech)

Caption NASA originale:"From its winter outpost at "Low Ridge" inside Gusev Crater, NASA's Mars Exploration Rover Spirit took this spectacular, color mosaic of hilly, sandy terrain and two potential iron meteorites. The two light-colored, smooth rocks about two-thirds of the way up from the bottom of the frame have been labeled "Zhong Shan" and "Allan Hills".

The two rocks' informal names are in keeping with the rover science team's campaign to nickname rocks and soils in the area after locations in Antarctica".
