Ironically—roughly and phonetically
speaking, "Cassini's" translates from
Farsi as "No one there?"

Cassini
On Wednesday, July 21, 2004, a few days before entering orbit around Saturn, the Cassini spacecraft captured this natural color view of Saturn's rings. The image was taken from below the ring plane at a distance of 4 million miles.
 
The rings are mostly water ice, which is white if it is pure. The different colors are therefore believed to reflect other materials, such as rock or carbon compounds.
