An ancient dark terrain surface is cut by orthogonal sets
of fractures on Jupiter's moon Ganymede. Subdued pits
visible on unbroken blocks are the remnants of impact
craters which have degraded with time. Across the top of
the image, a line of these subdued pits may have been a
chain of craters which are now cut apart by the northwest
to southeast trending fractures. North is to the top.
Younger craters appear as bright circles. The fractures
in this image range from less than 100 meters (328 feet)
to over a kilometer (0.62 miles) in width. They display
bright walls where cleaner ice may be exposed, and
deposits of dark material fill their floors. This 27 by
22 kilometer (17 by 14 mile) image of northern Marius
Regio was obtained on September 6, 1996 by NASA's Galileo
spacecraft at a resolution of 85 meters (278 feet) per
picture element (pixel). The Jet Propulsion Laboratory,
Pasadena, CA manages the Galileo mission for NASA's
Office of Space Science, Washington, DC. JPL is an
operating division of California Institute of Technology
(Caltech). This image and other images and data received
from Galileo are posted on the World Wide Web, on the
Galileo mission home page at URL
