This image was taken on August 01, 2005 and received on Earth August 02, 2005. The camera was pointing toward Rhea that was approximately 230,249 kilometres away.
The image was taken using the CL1 and GRN filters.

This image was taken on July 14, 2005 and received on Earth July 15, 2005. The camera was pointing toward Rhea approximately 204,829 kilometres away.
The image was taken using the CL1 and UV3 filters.

Saturn's moon Rhea displays two large impact features here, along the terminator (the boundary between day and night), plus a superb rayed crater to the east. Rhea is 1,528 kilometres across.
The northern basin, named Tirawa, was discovered in Voyager images. This ancient impact site is approximately 360 kilometres across. Another, perhaps larger basin sits to the south of Tirawa and is partly in shadow.



This view shows principally the leading hemisphere on Rhea; north is up and rotated about 10 degrees to the left.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on June 2, 2005, at a distance of approximately 1.8 million kilometres from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 47 degrees.
Resolution in the original image was 11 kilometres per pixel. The image has been contrast-enhanced and magnified by a factor of two to aid visibility.

Saturn's brightly sunlit moon Rhea commands the foreground in this image from Cassini. The planet's splendid rings are discernible in the background. Rhea is 1,528 kilometres across.

The spacecraft was just above the ring-plane when it acquired this image, and thus captured the darkened appearance of the dense B ring when viewed with sunlight filtered through the rings. From this perspective, bright areas in the rings are regions of low density, containing very small particles that effectively scatter light toward Cassini.
North on Rhea is up and rotated about 25 degrees to the left. This view shows principally the anti-Saturn hemisphere on Rhea. The right side of Rhea is overexposed.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Feb. 18, 2005, at a distance of approximately 540,000 kilometres from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 110 degrees.
The image scale is 3 kilometres per pixel.
