Smiling Tethys...

Caption originale:"The profile of Ithaca Chasma forms a great scar in the icy crescent of Tethys. The chasm stretches more than a 1.000 Km (about 620 miles) over Tethys' surface, from North to South.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 25, 2005 at a distance of approximately 313.000 Km (about 195.000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 151°. Image scale is about 2 Km (approx. 1 mile) per pixel".
