This 17-frame mosaic of Ganymede is composed of images obtained by Voyager 1 on March 5, 1979 over a period of about 2 hours. During these 2 hours Voyager 1's distance from Ganymede dropped from 305,000 to 180,000 km. The original GBV or OBV color images were used to create synthetic R, G and B color, resulting in approximately true color. In a few small areas only one or two colors were available; these areas were colorized by taking the color from nearby areas.
