Ganymede - Voyager 2

Close-up of Nipper Sulcus region on Jupiter's moon Ganymede

Close-up view of the Nipper Sulcus region of the Galilean satellite Ganymede as imaged by Voyager 2. This region exhibits complex sets of grooves which intersect at various angles and imply a very complicated tectonic history. The boundary between the dark and light terrain can be seen towards the bottom part of the frame. The frame is about 550 km across and is centered at 58 N, 200 W. The image was taken from 175,000 km and north is up. (Voyager 2, 20635.25)
