Voyager 2 Image of Ganymede



Voyager 2
July 7, 1979

This image clearly shows the large dark area Regio Galileo, was well as much of the lighter grooved terrain discovered by Voyager 1. The bright spots are impact craters. This image also shows what appears to be polar caps, extending down to about latitude 45 degrees in both the norther and southern hemispheres.
