A joint NASA/ESA mission to explore the Saturnian system, including Saturn's atmosphere, rings and magnetosphere, and some of its moons - Titan and the icy satellites.The spacecraft comprise NASA's Cassini Orbiter and ESA's Hugyens Probe


The orbiter is named after Jean-Dominique Cassini (1625-1712), a French-Italian astronomer who identified the gap between Saturn's rings (the Cassini division) The Probe is named after Christiaan Huygens (1629-1695), a Dutch astronomer who discovered the Saturn's rings and, in 1655, its largest moon Titan.

  To reach Saturn, Cassini/Huygens used a series of gravity-assist manoeuvers, with the following swingbys:
· Venus 27 April 1998
· Venus 24 June 1999
· Earth 18 August 1999
· Jupiter 30 December 2000
