CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Callisto Mosaic

Callisto was revealed by the Voyager cameras to be a heavily cratered and hence geologically inactive world. This mosaic of Voyager 1 images, obtained on March 6 from a distance of about 400,000 kilometers, shows surface detail as small as 10 kilometers across. The prominent old impact feature Valhalla has a central bright spot about 600 kilometers across, probably representing the original impact basin. The concentric bright rings extend outward about 1,500 kilometers from the impact center.

The Voyager Project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.

Acquired: March 1979
