For Enceladus, wrinkles mean the opposite of old age. This view of a crescent Enceladus shows a transition zone between a wrinkled and presumably younger region of terrain and an older, more heavily cratered region. The moon's geologically active southern polar region is seen at bottom.
The lit terrain shown here is on the side of Enceladus (504 kilometers, 313 miles across) that faces away from Saturn. North is up and rotated 20 degrees to the right.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 24, 2005 at a distance of approximately 108,000 kilometers (67,000 miles) from Enceladus and at a Sun-Enceladus-spacecraft, or phase, angle of 102 degrees. Image scale is 646 meters (2,118 feet) 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.
