CICLOPS: Cassini Imaging Central Laboratory for OPerationS

Wisps on Dione
[For trouble viewing the images/movies on this page, go here]
Cassini spies bright fractures in the icy crust of Dione. These bright "linea" cover the moon's trailing hemisphere, and were imaged by Cassini at high resolution in 2005 (see PIA07638).

This view looks toward the northern hemisphere on Dione's anti-Saturn side. North on Dione (1,123 kilometers, 698 miles across) is up and rotated 33 degrees to the right.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 1, 2007 at a distance of approximately 1.8 million kilometers (1.1 million miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 60 degrees. Image scale is 11 kilometers (7 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.
