Dione's Wispy Terrain


Wispy terrain winds across the trailing hemisphere of Saturn's moon Dione in this Cassini view taken during the spacecraft's Jan. 27, 2010 non-targeted flyby.

Cassini came within about 45,000 kilometers (28,000 miles) of the moon during this flyby, but this image was acquired at a distance of approximately 137,000 kilometers (85,000 miles) from Dione. See PIA06163 for an older, closer view of Dione's wispy fractures. This view looks toward the anti-Saturn side and trailing hemisphere of Dione (1,123 kilometers, or 698 miles across). North on Dione is up.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Jan. 27, 2010. The view was obtained at a Sun-Dione-spacecraft, or phase, angle of 38 degrees. Image scale is 819 meters (2,687 feet) per pixel.
