Quiet and cold, a crescent Tethys floats above the nearly edge-on rings of Saturn. The only surface features visible on Tethys (1,062 kilometers, 660 miles across) from this distance are a few impact craters.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 22, 2006, at a distance of approximately 3 million kilometers (1.8 million miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 115 degrees. The image scale is 18 kilometers (11 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.
