New Cassini Images of Titan, Tethys and Methone.

The Cassini Space Probe was launched on 15 October 1997 from Cape Canaveral Air Force Station and entered orbit around Saturn on 30 June 2004. It has been sending back data on and images of the planet, its moons and its ring system ever since. This month it has produced a number of new images of three of Saturn's moons, Titan, Tethys and Methone.

Titan is the largest moon of Saturn, and the second largest in the Solar System (after Jupiter's moon Ganymede). It is the only moon in the Solar System with a dense atmosphere and has a volume 17% larger than that of Mercury. On 14 January 2005 the Huygens Probe, which had been launched from Cassini, landed on the surface of Titan, beaming bake images of a world with lakes and rivers of hydrocarbons at the surface.

Tethys is the 5th largest moon of Saturn and the 16th largest moon in the Solar System. This makes it the smallest large moon in the Solar System, having a greater mass than all the smaller moons combined. It has an icy, crater covered, surface and a low density, causing scientists to believe it is largely made of ice.

Methone is a minor moon of Saturn that was discovered by the Cassini Probe in 2004. It is smooth and egg-shaped, with an average radius of 1.6 km.
