Two large craters and hints of several smaller ones are visible in this Cassini image of Saturn's icy moon Tethys (1060 kilometers, or 659 miles, across).
The image was taken in visible light with the Cassini spacecraft narrow angle camera on Sept. 23, 2004, at a distance of 7.9 million kilometers (4.9 million miles) from Tethys and at a Sun- Tethys-spacecraft, or phase, angle of 80 degrees. The image scale is 48 kilometers (30 miles) per pixel. The image has been contrast-enhanced and magnified by a factor of four to aid visibility.
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 Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute, Boulder, Colo.
