This view of a part of the Galileo Regio region on Jupiter's moon
Ganymede shows fine details of the dark terrain that makes up
about half of the surface of the planet-sized moon. One of many
ancient impact craters in the region is visible at the middle
left. The crater is cut by numerous fractures, showing that the
ancient crust was highly deformed early in Ganymede's history.
Dark areas may have originated from dark material thrown off by
dark meteorites hitting the surface in thousands of impact
events. In this view, north is to the top and the sun
illuminates the surface from the lower left about 58 degrees
above the horizon. The area shown, at latitude 19 degrees north,
longitude 149 degrees west, is about 19 by 26 kilometers (12 by
16 miles); resolution is about 80 meters (262 feet) per pixel.
The image was taken June 27 at a range of 7.652 kilometers (4,755
miles). The Jet Propulsion Laboratory manages the Galileo
mission for NASA's Office of Space Science.
