Saturn's moon Hyperion appears to tumble toward Cassini in this movie that shows variations in color across the moon's surface.

The movie was created from 14 frames and represents about 12 hours as the spacecraft encountered Hyperion in early 2006. Most of the observable motion is due to the spacecraft's trajectory during the flyby.

The dark areas in the bottoms of craters are seen on all parts of Hyperion.

To create the false-color view in each frame, ultraviolet, green and infrared images were combined into a single picture that isolates and maps regional color differences. This "color map" was then superimposed over a clear-filter image that preserves the relative brightness across the body.

The combination of color map and brightness image shows how colors vary across Hyperion's surface. The origin of the color differences is not yet understood, but may be caused by subtle differences in the surface composition or the sizes of grains making up the icy surface material.

Hyperion is 280 kilometers (174 miles) across. The images were taken with the Cassini spacecraft narrow-angle camera on Feb. 23, 2006, at a distance ranging from 1.3 million to 1 million kilometers (800,000 to 600,000 miles) from Hyperion. Image scale is about 4 kilometers (2 miles) per pixel.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
