Southern Hemisphere Craters


The set of images shown here in color was acquired as part of a sequence intended to monitor any changes in the calibration of the multispectral Wide Angle Camera over time, but it also gives a beautiful view of Mercury's cratered southern hemisphere. The craters Magritte, Neruda, and Sher-Gil can be spotted within this scene. North is to the top-left of the image.
