CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Dionean Linea

Bright icy fractures, or linea, cover the trailing hemisphere of Saturn's moon, Dione. Cassini imaged the fractured terrain at high resolution in Oct. 2005 (See PIA07638).

Lit terrain seen here is on the trailing hemisphere of Dione (1,123 kilometers, 698 miles across). North is up.

The image was taken with the Cassini spacecraft narrow-angle camera using a spectral filter sensitive to wavelengths of infrared light centered at 930 nanometers. The image was taken on Feb. 3, 2007 at a distance of approximately 927,000 kilometers (576,000 miles) from Dione. Image scale is 6 kilometers (3 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 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.
