Sinking in a Sea of Darkness...

The Cassini spacecraft captured this glimpse of icy Epimetheus just before the small moon disappeared behind the bulk of Saturn's atmosphere.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 20, 2005, at a distance of approx. 2,3 MKM (about 1,4 MMs) from Epimetheus and 2,2 MKM (about 1,3 MMs) from Saturn. The image scale is roughly 14 Km (about 9 miles) per pixel on Epimetheus and approx. 13 Km (about 8 miles) per pixel on Saturn.
