Highest resolution view ever obtained of Ganymede's dark terrain This mosaic, composed of Galileo SSI images taken during its May 20, 2000 flyby of Ganymede, shows the highest resolution view ever obtained of Ganymede's dark terrain, which makes up about one third of Ganymede's surface. North is to the top of the images and the Sun illuminates the surface from the west. The resolution is 28 meters (92 feet) per pixel. NASA / JPL / OWW
