Mimas's lit crescent has the appearance of a golf ball thanks to its heavily cratered surface.
The image was taken with the Cassini spacecraft narrow-angle camera on Oct. 24, 2008 using a spectral filter sensitive to wavelengths of infrared light centered at 752 nanometers. The view was obtained at a distance of approximately 189,000 kilometers (117,000 miles) from Mimas and at a Sun-Mimas-spacecraft, or phase, angle of 136 degrees. Image scale is 1 kilometer (3,707 feet) per pixel.
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.
