A global image mosaic assembled by incorporating the best available imagery from NASA's Voyager 1 and 2 spacecrafts and NASA's Galileo spacecraft, released on Feb. 12, 2012.
Our solar system’s largest moon, Ganymede of Jupiter, has never been completely mapped — until now. Scientists led by Wheaton College’s Geoffrey Collins combined data from NASA’s Voyager 1, 2 and Galileo spacecrafts to create this, the first global geologic map of icy Ganymede, Jupiter’s seventh moon.
“This map illustrates the incredible variety of geological features on Ganymede and helps to make order from the apparent chaos of its complex surface,” NASA’s Jet Propulsion Laboratory’s Robert Pappalardo said of the Ganymede map. “This map is helping planetary scientists to decipher the evolution of this icy world and will aid in upcoming spacecraft observations.”
