   Dione (1,123 kilometers, 698 miles across) shows Cassini some of the bright wispy streaks that cover much of the moon's trailing hemisphere. The streaks are thought to be deposits of icy material that has been extruded onto the moon's surface from the interior.

The image was taken in visible light with the narrow angle camera on September 28, 2004, from a distance of 7.3 million kilometers (4.5 million miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 79 degrees. The image scale is 44 kilometers (27 miles) per pixel. The image has been magnified by a factor of four to aid visibility.

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.
