Researchers claim that the new map of Ganymede is the first comprehensive global geologic map of an icy moon of an external planet. The U. S. Geological Survey has issued the map, which shows the diverse geology on Ganymede’s surface. The geologic map of Ganymedeis accessible for download online here. USGS Astrogeology Science Center administrator Laszlo Kestay said:  “After Mars, the interiors of icy satellites of Jupiter are considered the best candidates for habitable environments for life in our solar system. This geologic map will be the basis for many decisions by NASA and partners regarding future U.S. missions under consideration to explore these worlds.”

The video above displays a simulation of a revolving globe of Jupiter’s moon Ganymede, with a geologic map covered over a global color mixture. The 37-second animation initiates as a global color mosaic appearance of the moon then rapidly fade away into the geologic map. The misrepresentation in the shape of Ganymede is a map-maker’s objet d'art. Ganymede is round, just like Planet Earth.
