example of the light terrain of Ganymede. The image shows the
contrast between the light terrain and the dark terrain of
Ganymede. The light terrain is where the grooves of Ganymede are

exploratory mission, specifically targetted Uruk Sulcus, to
examine the surface for changes. Shop Windows to the Universe
