Cassini continues to survey the small worlds that orbit near Saturn's rings, capturing this view of Epimetheus. The moon's lumpy, irregular topography can be seen here, along with several impact craters. Epimetheus is 116 kilometers (72 miles) across.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 20, 2005, at a distance of approximately 345,000 kilometers (214,000 miles) from Epimetheus and at a Sun-Epimetheus-spacecraft, or phase, angle of 26 degrees. Resolution in the original image was 2 kilometers (1 mile) per pixel. The view was magnified by a factor of two and contrast-enhanced to aid visibility of the moon's surface. A closer view of Epimetheus, taken from a different viewing angle is also available (see Epimetheus: Up-Close and Colorful).
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 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.
