Grand_Lunar:

There will be an Iapetus flyby earlier than first planned. When the Huygens entry was pushed back from November '04 to January '05, 2 additional early orbits with close Titan encounters were added. By chance the orbit on which the Huygens probe is released comes relatively close to Iapetus. Otherwise, the close flyby (1000-2000 km) of that satellite comes in September 2007.

Here are some links I posted in another thread.

December 13 Titan encounter. I don’t know why but the Huygens entry site is shown at the right longitude (~160 E) but wrong latitude (18 N). It should be at 11 S., just below the dark patch (hydrocarbon lake ??)

QuickTime animations of the entire orbit tour (255 MB! – about 40 minutes to download on DSL), all Iapetus views during the mission, and a detailed version of the Dec 31 –Jan 01 (UTC) flyby. This part of Iapetus was either not imaged or at only ~20-30 km/pixel by Voyager. The best Cassini images should be <400 m/pixel.
