Trailing Wisps
Date: 20 Dec 2010

Wispy terrain reflects sunlight brightly in the lower left of this Cassini image of the northern latitudes of Saturn's moon Dione.


These "wisps" are actually fractures on the trailing hemisphere of Dione. See PIA10560 to learn more.


Lit terrain seen here is between the trailing hemisphere and the Saturn-facing side of Dione (1,123 km, or 698 miles across). North is up.


The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 20, 2010. The view was obtained at a distance of approximately 107,000 km (67,000 miles) from Dione and at a sun-Dione-spacecraft, or phase, angle of 109 degrees. Image scale is 640 m (2,100 feet) per pixel.
