The image above shows a stereographic projection of a mosaic centered on Mercury's north pole. This mosaic is made up of MDIS images acquired during its monochrome, color, monochrome stereo, high-incidence, albedo, three-color, and northern polar campaigns. Above 85 degrees north, the approximate location of the center of Prokofiev crater, many images were averaged together in order to obtain a mostly sunlit mosaic. Permanently shadowed craters at Mercury's poles are host to radar-bright deposits. Tune in on Thursday, November 29, to a NASA news conference about exciting new science results about Mercury's polar regions.
