Faces of Shackleton

This image shows four "faces" of Shackleton Crater, a 21 km diameter crater located at the south pole of the Moon. Because of its location, most of Shackleton's interior lies in permanent shadow. In the upper left, topography from the LOLA laser altimeter reveal the shape of the crater interior. The upper right image shows the visible lighting conditions in an image from the SMART-1 mission. The lower right image is a lighting map (brighter is longer periods of illumination) from the LRO Camera. The lower left image is a radar image from the Mini-RF instrument draped over a shaded relief map.
