Tethys (natural colors - elab. Lunexit)

Caption NASA:"Ithaca Chasma rips across Tethys from North to South near the center of this view. The moon's western limb is flattened, indicating the rim of the giant impact basin Odysseus.
The dark, East-West trending band often observed in this region (see PIA07571) is just visible here, but its contrast is reversed at these short, ultraviolet wavelengths -- it is bright against the already bright terrain.
North on Tethys (1071 Km, or about 665 miles across) is up and rotated 24° to the left. This view looks toward the moon's Saturn-Facing Hemisphere.
The image was taken with the Cassini spacecraft narrow-angle camera on May 27, 2007 using a combination of spectral filters sensitive to wavelengths of light centered at 298 and 338 nanometers. The view was obtained at a distance of approx. 267.000 Km (about 166.000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 13°.
Image scale is roughly 2 Km (5.236 feet) per pixel".
