Odysseus

Original caption:"Plunging cliffs and towering mountains characterize the gigantic impact structure called Odysseus on Saturn's moon Tethys. The great impact basin lies before the Cassini spacecraft in one of the best views yet obtained.
Quite a few small craters are visible inside Odysseus (450 Km - or 280 miles across), making it clear that this is not a very young structure. However, a comparison of cratering density between the interior of Odysseus and the surrounding terrain should show whether the large basin is at least relatively young.
Odysseus lies on the Leading Hemisphere of Tethys; North is up and rotated 18° to the right.

The image was taken in polarized ultraviolet light with the Cassini spacecraft narrow-angle camera on Dec. 24, 2005 at a distance of approx. 196.000 Km (about 122.000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 85°. Resolution in the original image was about 1 Km (3,831 feet) per pixel. The image has been magnified by a factor of two and contrast-enhanced to aid visibility".
