The Cassini mission home page is at "Cassini-Huygens: Mission to Saturn and Titan", http://saturn.jpl.nasa.gov/home/index.cfm

Cassini has produced so many fantastic picures that it's hard to know where to start. One good place is the Cassini "Favourite Image" contest: http://ciclops.org/contest07.php?js=1

Alan Taylor - the same chap who made the "All Solar System Bodies" image I recommended last week - has a selection of his favourite Cassini images at http://www.boston.com/bigpicture/2009/04/cassinis_continued_mission.html. He's very fond of the weird optical effects when the rings are refracted through the edge of Saturn's atmosphere, but they're certainly a gorgeous collection. If that's not enough, click on the "Previously" links to get more.

A complete up-to-date list of all of Saturn's satellites can be found at Scott Sheppard's "The Jupiter Satellite Page", http://www.ifa.hawaii.edu/~sheppard/satellites/ because it's subtitled "Now also the Giant Planet Satellite and Moon Page"

The Planetary Society has excellent pages about Saturn's rings and moons, at http://www.planetary.org/saturn/rings.html and http://www.planetary.org/saturn/moons.html

Two different views for the ages of Saturn's rings can be found at "Science@NASA: The Real Lord of the Rings", http://science.nasa.gov/headlines/y2002/12feb_rings.htm and "Saturn's rings may not be as young as they look" http://www.sciencenews.org/view/generic/id/36716/title/Saturns_rings_not_as_young_as_they_look

Great silliness: The Cassini CICLOPS team have written a game, so you can see what it's like playing golf in the differing gravity environments of Saturn's moons. It's surprisingly easy to lose your ball off the moon completely! http://ciclops.org/sector6/golf.php Sources for images used: All images of Saturn and its moons are from the NASA Planetary Photo Journal http://photojournal.jpl.nasa.gov/target/Saturn, unless otherwise indicated. I have given the Planetary Image Archive (PIA) number for each image
