Radar imaging of the north pole of Mercury on top of a mosaic of images taken by the Mercury Messenger spacecraft in the same area. All the large ice deposits in the polar region are located on the bottom or walls of impact craters. Deposits far from the pole appear to have been concentrated on the north-facing side of craters.
