Impact on Saturn's moon Rhea
Saturn's moon Rhea shows off a bright, rayed crater near its eastern limb in this image from the NASA/ESA/ASI Cassini-Huygens spacecraft.
Rhea is about half the size of Earth's moon. At 1528 kilometres across, it is the second largest moon orbiting Saturn. Cassini-Huygens will image this hemisphere of Rhea again in mid-January 2005, just after the Huygens probe touchdown on Titan - with approximately one-kilometre resolution.
The image was taken in visible light with the Cassini-Huygens spacecraft narrow-angle camera on 24 October 2004, at a distance of about 1.7 million kilometres from Rhea. The image scale is approximately 10 kilometres per pixel.
The Cassini-Huygens mission is a co-operative project of NASA, ESA and ASI, the Italian space agency.
