Dione: North Polar View
Date: 22 Mar 2008
The Cassini spacecraft looks down, almost directly at the north pole of Dione. The feature just left of the terminator at bottom is Janiculum Dorsa, a long, roughly north-south trending ridge.
Lit terrain seen here is on the anti-Saturn and trailing sides of Dione (1,126 km, or 700 miles across).The image was taken with the Cassini spacecraft narrow-angle camera on 22 March 2008 using a spectral filter sensitive to wavelengths of ultraviolet light centered at 338 nm. The view was acquired at a distance of approximately 650,000 km (404,000 miles) from Dione and at a sun-Dione-spacecraft, or phase, angle of 99 degrees. Image scale is 4 km (2 miles) per pixel.
