Craters cover the rugged surface of Saturn's moon Janus.
The view is from 42 degrees above the moon's equator. North on Janus (179 kilometers, 111 miles across) is up.
The image was taken with the Cassini spacecraft narrow-angle camera on May 17, 2008 using a combination of spectral filters sensitive to wavelengths of polarized green light centered at 617 and 568 nanometers. The view was acquired at a distance of approximately 350,000 kilometers (217,000 miles) from Janus and at a Sun-Janus-spacecraft, or phase, angle of 101 degrees. Image scale is 2 kilometers (1 mile) 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.
