  The great eye of Mimas ... a 130 kilometer- (80 mile-) wide impact crater called Herschel ... stares out from the battered moon. Several individual ringlets within the F ring are resolved here, and the small moon Atlas is also faintly seen outside the main rings.

Mimas is 396 kilometers (246 miles across); the view shows principally the moon's anti-Saturn hemisphere. Atlas is 30 km (19 miles) across.

The image was taken in visible light with the narrow angle camera on April 5, 2005, from a distance of approximately 2.1 million kilometers (1.3 million miles) from Mimas and at a Sun-Mimas-spacecraft, or phase, angle of 72 degrees. The image scale is 13 kilometers (8 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.
