20 July: Since Cassini emerged from behind the Sun on 12 July the probe has been sending a slew of data back home, including photos of several of Saturn's moons. This picture of Rhea's ancient, cratered surface was taken on 2 July. With a diameter of 1,528 kilometres, Rhea is Saturn's second largest moon. Cassini is slated to fly past Rhea at a distance of only 500 kilometres on 26 November 2005. The spaceship has also returned similar images of Tethys, Enceladus and Dione, all of which will get closer fly-bys later in the probe's mission.
