  This raw, unprocessed image of Tethys was taken on August 14, 2010 and received on Earth August 14, 2010. The camera was pointing toward TETHYS at approximately 48,572 kilometers away, and the image was taken using the CL1 and CL2 filters. This image has not been validated or calibrated. A validated/calibrated image will be archived with the NASA Planetary Data System in 2011.

The Cassini Equinox Mission is a joint United States and European endeavor. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter was designed, developed and assembled at JPL. 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.

Awesome images. A couple of trivial questions:
1) Given that it takes several hours for signals to travel each way to/from Cassini, how does Cassini know which geological features to fotograph or to focus on?
2) What is the cause of these geological features that look like some colossal scratching of the surface?
