This picture of Callisto was taken by Voyager 2 on July 7 from a distance of 2,318,000 kilometers (1,438,000 miles). Callisto is covered with bright spots which are meteorite impact craters -- a fact originally discovered from the high resolution pictures taken by Voyager 1 last March. Scientists believe that heavily cratered terrains like these on Callisto are indicative of ancient planetary surfaces. Voyager 2 will fly by the lower left part of the satellite and map the side not seen by Voyager 1. The obscure dark streaks in this area may be fault zones, but higher resolution pictures in the next two days will allow them to be identified.
