  The northern polar region of Tethys, seen in this Cassini flyby image, is a ponderously ancient surface.

Above the prominent peaked crater Telemachus are the remnants of a very old crater (at the 10 o'clock position relative to Telemachus) named Teiresias. The ancient impact site is so badly overprinted and eroded by impact weathering and degradation that all that remains is a circular pattern of hummocks that mark where the old crater rim existed.

This view is centered on terrain at approximately 1.2 degrees south latitude and 342 degrees west longitude on Tethys. The view is rotated so that north is about 40 degrees to the right.

This clear filter view was taken during Cassini's close approach to Tethys on September 1,062 kilometers (660 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 21 degrees. Image scale is 410 meters (1,350 feet) 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.
