Cassini-Huygens is a joint NASA/ESA unmanned space mission intended to study Saturn and its moons. The spacecraft consists of two main elements: the Cassini orbiter and the Huygens probe. It was launched on October 15, 1997 and is estimated to enter Saturn's orbit on July 1, 2004.

The mission also includes contributions from ASI, the Italian Space Agency. There are 17 member nations in all, with another few nations having contributed smaller amounts of funding.

"Cassini–Huygens is a joint NASA/ESA/ASI robotic spacecraft mission currently studying the planet Saturn and its moons. The spacecraft consists of two main elements: the NASA Cassini orbiter, named after the Italian-French astronomer Giovanni Domenico Cassini, and the ESA Huygens probe, named after the Dutch astronomer, mathematician and physicist Christiaan Huygens. It was launched on October 15, 1997 and entered into orbit around Saturn on July 1, 2004. On December 25, 2004 the Huygens probe separated from the orbiter at approximately 02:00 UTC; it reached Saturn's moon Titan on January 14, 2005 where it made an atmospheric descent to the surface and relayed scientific information. On April 18, 2008, NASA announced a two year extension of the mission. Cassini is the first spacecraft to orbit Saturn and the fourth to visit it."
