The soft appearance of Dione's wispy terrains belies their true nature. They are, in fact, complex systems of crisp, braided fractures that covers the moon's trailing hemisphere (see PIA06162 for a closer view of the fractures).
This view shows the western potion of the wispy terrain on Dione (1,123 kilometers, 698 miles across). The craters Dido and Antenor can be seen near the terminator at lower left.
In the rings above, the dark Cassini Division between the A and B rings is visible.
The image was taken in visible light with the Cassini narrow-angle camera on Oct. 9, 2005, 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 52 degrees. The 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.
