Cassini photos of Saturn and its environs

Cassini photos of Saturn, its rings, and its moons, as seen here http://www.boston.com/bigpicture/2009/04/cassinis_continued_mission.html, are simultaneously amazing and awe-inspiring. It is further serendipity that I am currently reading Jack McDevitt's Academy series; the one where the first book features the monument on Iapetus, whose surface is captured in glorious detail by Cassini.
