The Odyssey on Tethys...

Caption NASA:"This Cassini Spacecraft image provides a view of the southern portion of Tethys' Trailing Hemisphere.
Prominent features include the huge canyon, Ithaca Chasma, approximately centered in this view, as well as Demodocus and Telemus, large basins just to the right of the rift.
Features on Tethys are named for characters in Homer's Odyssey.

The image was taken in visible green light with the Cassini Spacecraft narrow-angle camera on Oct. 10, 2008 at a distance of approx. 417.000 Km (about 259.000 miles) from Tethys and at a Sun-Tethys-Spacecraft, or Phase, angle of 55°.
Image scale is roughly 2 Km (a little more than 1 mile) per pixel".
