Rhea's ancient surface
The NASA/ESA/ASI Cassini spacecraft obtained this image of Saturn's moon Rhea on 1 November 2004, at a distance of 1.6 million kilometres.
The sunlight angle in this sharp view of Rhea, Saturn's second-largest moon, highlights the moon's crater-strewn surface. This view shows mainly the hemisphere of Rhea that faces away from Saturn. The image was taken in visible light with the Cassini spacecraft narrow-angle camera. North is up.
Cassini will fly past Rhea on 26 November 2005, at a distance of only 500 kilometres and will obtain very high resolution images at that time. Rhea's diameter is 1528 kilometres.
The Cassini-Huygens mission is a co-operative project of NASA, ESA and ASI, the Italian space agency.
