The dramatic Ithaca Chasma carves an enormous gash for more than 1,000 kilometers (620 miles) across Tethys (1,062 kilometers, 660 miles across). Stretching across the top of this view are the B and A rings, separated by the Cassini Division.
Ithaca Chasma is on the moon's Saturn-facing hemisphere. North on Tethys is up and rotated 15 degrees to the left in this view.
The image was taken in visible light with the narrow angle camera on August 24, 2005, from a distance of approximately 2.2 million kilometers (1.3 million miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 87 degrees. The image scale is 13 kilometers (8 miles) per pixel.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
