  Mimas (396 kilometers, 246 miles across) has many large craters, but Herschel crater dwarfs all the rest. This large crater (130 kilometers, 80 miles wide) has a prominent central peak, seen here almost exactly on the terminator. This cater is the moon's most prominent feature and the impact that formed it probably nearly destroyed Mimas.

This view is predominantly of the leading hemisphere of Mimas. The image has been rotated so that north on Mimas is up.

This image was taken with the narrow angle camera on January 16, 2005, from a distance of approximately 213,000 kilometers (132,000 miles) from Mimas and at a Sun-Mimas-spacecraft, or phase, angle of 84 degrees. Resolution in the original image was about 1.3 kilometers (0.8 miles) per pixel. A combination of spectral filters sensitive to ultraviolet and polarized light was used to obtain this view. Contrast was enhanced and the image was magnified by a factor of two 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 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.
