Mercury - MESSENGER
Two frame MDIS Wide-Angle Camera mosaic of Mercury taken on May 24, 2011. At the time this photo was taken, MESSENGER was high over the southern hemisphere, looking nearly directly down on the south pole from an altitude of 15,800 km. This mosaic captures the hemisphere centered on 0 W. The crater Chao Meng-Fu, which sits nearly on top of the south pole, is the crater just right of center along the terminator.
