Ganymede Color

This is a natural color view of Ganymede from the Galileo spacecraft during its first encounter with the satellite. North is to the top of the picture, and the sun illuminates the surface from the right. The dark areas are the older, more heavily cratered regions, and the light areas are younger, tectonically deformed regions. The brownish-gray color is due to mixtures of rocky materials and ice. Bright spots are geologically recent impact craters and their ejecta. The finest details that can be discerned in this picture are about 13.4 kilometers across. The images that make up this color photo were taken in June 1996.
