The Cassini spacecraft flew by the Saturnian moon Iapetus on December 31, 2004 and snapped some images. The moon is recognizable because of it has one bright side and one dark side, perhaps due to sweeping up debris on its leeward side as it orbits Saturn. Cassini will pass much closer to the moon around September 10, 2007.
