The hemisphere of Ganymede that faces away from the Sun displays a great variety of terrain. In this Voyager 2 mosaic, photographed at a range of 300,000 kilometers, the ancient dark area of Regio Galileo lies at the upper left. Below it, the ray system is probably caused by water-ice, splashed out in a relatively recent impact.
The Voyager Project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
