The "sharp" G-Ring

This contrast-enhanced view of Saturn's faint G-Ring shows its extremely sharp inner edge and more diffuse outer boundary. Using its large high-gain antenna as a shield, the Cassini spacecraft flew through the Region interior to the G-Ring during insertion into Saturn orbit. The spacecraft was struck many times by the fine icy particles that populate the Region between the F and G Rings.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Jan. 19, 2006, at a distance of approx. 1,2 MKM (such as about 700.000 miles) from Saturn. The image scale is about 7 Km (approx. 4 miles) per pixel.
