  This unprocessed image was taken during Cassini's close approach to Tethys on June 27, 2007.

The image was taken with the Cassini spacecraft narrow-angle camera at a distance of approximately 37,000 kilometers (23,000 miles) from Tethys. Image scale is 219 meters (718 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.

Tommy....almost certainly a cosmic ray hit on the CCD.

Using panorama software I created two mosaics from the raw data:

Using panorama software makes for pretty easy mosaics, but the result isn't perfect though. The missing piece in the large one should be rectangular for example. To fix that I'm redoing it by hand in Photoshop. Pretty hard to do and it takes many hours, so fo the time being I like the panorama software result fine ;)

In between the 9 o'clock and 10 o'clock on the outside of the great impact basin, there's a very straight protrusion, bisected by an odd shape. Dust in the filter?
