Tethys, in full light (natural colors; credits: Lunexit)

Caption NASA:"Five hours after acquiring PIA10460, the Cassini Spacecraft turned its cameras back to Tethys for a more southerly view. The southern reaches of Ithaca Chasma are seen here, along with the large crater Telemus, just right of center.
Lit terrain seen here is on the Saturn-Facing Side of Tethys (approx. 1062 Km, or 660 miles across).
This view looks toward the Southern Hemisphere from a perspective 43� South of the moon's Equator. North is toward the top and rotated 30� to the right.

The image was taken in visible green light with the Cassini Spacecraft narrow-angle camera on July 28, 2008. The view was obtained at a distance of approx. 313.000 Km (such as about 194.000 miles) from Tethys and at a Sun-Tethys-Spacecraft, or Phase, Angle of 42�.
Image scale is roughly 2 Km (a little more than 1 mile) per pixel".
