New Images Reveal a Dark Side
The double-ring basin at the top of this image was previously imaged on July 20, 2011, as part of MDIS's surface morphology base map. The previous image showed details of the basin's peak-ring structure, but the image shown here, acquired as part of MDIS's color base map, reveals the dark material on the basin floor.
