Caption: Mars Polar Lander's primary landing site. The landing site at 76 degrees south latitude and 195 degrees west longitude is marked on a polar stereographic map of Mars' south pole. The bright, permanent carbon dioxide polar cap is offset slightly from the rotational pole. The polar layered deposits, a blanket of dust and ice layers which may be an interpretable record of Martian climate history, is outlined in white. Image credit: Dr. David A. Paige (UCLA).
