Dione


Like the Voyager spacecraft that came before, the Cassini spacecraft chronicles "wispy" terrain on Saturn's moon Dione.

See PIA10560 to view another image of these bright fractures on the moon's trailing hemisphere. This view looks toward the area between the Saturn-facing side and trailing hemisphere of Dione (1,123 kilometers, or 698 miles across). North is up.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on December 26, 2009. The view was acquired at a distance of approximately 1 million kilometers (621,000 miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 42 degrees. Image scale is 6 kilometers (4 miles) per pixel.
