Radar Bright Deposits in Mercury's Polar Craters
A radar image of Mercury's north polar region is shown superposed on a mosaic of MESSENGER images of the same area. All of the larger polar deposits are located on the floors or walls of impact craters. Deposits farther from the pole are seen to be concentrated on the north-facing sides of craters. These polar deposits have been hypothesized to consist of water ice.
