Caption:

The profile of Ithaca Chasma forms a great scar in the icy crescent of Tethys. The chasm stretches more than 1,000 kilometers (620 miles) over Tethys' surface, from north to south.

Tethys is 1,071 kilometers (665 miles) wide.

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 kilometers (195,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 151 degrees. Image scale is 2 kilometers (1 mile) per pixel. North on Tethys is up in this view.
