Cassini-Huygens caught a hint of Rhea's heavily cratered surface as it sped rapidly away from the moon on its first orbit of Saturn. There is a noticeable brightening near the left limb of the icy moon. Cassini-Huygens will have its first fly-by of Rhea in November 2005.
The image was taken in visible light with the Cassini-Huygens spacecraft narrow-angle camera on 20 July 2004, from a distance of 5.9 million kilometres from Rhea. The image scale is 35 kilometres per pixel. The image has been magnified by a factor of four to aid visibility.
