Galileo obtained the images that make up this mosaic of Ganymede's Nippur Sulcus region when it flew past Jupiter's moon Ganymede for the second time on September 6, 1996. The Nippur Sulcus region is an example of Bright Terrain on Ganymede, which is typified by multiple sets of ridges and grooves. The intersections of these sets reveal complex age relationships. North is to the top of the picture and the sun illuminates the surface from the southeast (lower right). This mosaic was created by unmannedspaceflight.com user OWW.
