  This extreme false-color view of Hyperion shows color variation across the impact-blasted surface of the tumbling moon.

To create this false-color view, ultraviolet, green and infrared images were combined into a single picture that isolates and maps regional color differences. This "color map" was then superposed 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 in relation to geologic features. 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 on Hyperion (270 kilometers, 168 miles across).

The images used to create this view were acquired using the Cassini spacecraft narrow-angle camera on June 28, 2006 at a distance of approximately 294,000 kilometers (183,000 miles) from Hyperion. Image scale is 2 kilometers (1 mile) 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 Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
