Cassini ends August with back-to-back fly-bys of Rhea and then Titan.
First up, on Aug. 30, the spacecraft flies within 5,737 kilometers (3,565 miles) of Saturn's second largest moon, Rhea. The icy moon provides a stark contrast to the atmosphere-rich Titan, which gets its close up this time from 3,326 kilometers (2,066 miles) the next day. These fly-bys set up a close encounter with Iapetus on Sept. 10, 2007.
