Summary

True-color full-face image of Callisto by spacecraft Galileo.

Original caption

Bright scars on a darker surface testify to a long history of impacts on Jupiter's moon Callisto in this image of Callisto from NASA's Galileo spacecraft.

The picture, taken in May 2001, is the only complete global color image of Callisto obtained by Galileo, which orbited Jupiter from December 1995 until September 2003. Of Jupiter's four largest moons, Callisto orbits farthest from the giant planet.

Callisto's surface is uniformly cratered but is not uniform in color or brightness. Scientists believe the brighter areas are mainly ice and the darker areas are highly eroded, ice-poor material.

The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Galileo mission for NASA's Office of Space Science, Washington, D.C.
