Cassini-Huygens.
Named after Giovanni Domenico Cassini (1625-1712), also known as Jean-Dominique Cassini, a 17th Century Italian-French astronomer who discovered the 2nd, 3rd, 4th and 5th moons (Iapetus on Oct 25 1671, Rhea on Dec 23, 1672, Dione and Tethys on March 21, 1684) of Saturn to be discovered, and after Christiaan Huygens, the Dutch astronomer who discovered Titan, Saturn's largest moon, on March 25, 1655.
Cassini-Huygens is a joint NASA/ESA/ASI unmanned space mission intended to study Saturn and its moons. The spacecraft consists of two main elements: the NASA Cassini orbiter, and the ESA Huygens probe. It was launched on October 15, 1997 and is the first spacecraft to orbit Saturn and the fourth spacecraft to visit Saturn.
On July 1, 2004, the Cassini-Huygens spacecraft performed the SOI (Saturn Orbit Insertion) maneuver and entered into orbit around Saturn. Before the SOI, Cassini had already studied the system extensively. In June 2004, it had conducted a close flyby of Phoebe sending back high-resolution images and data.
The orbiter completed two Titan flybys before releasing the Huygens probe on December 25, 2004. Huygens descended onto the surface of Titan on January 14, 2005, sending a flood of data during the atmospheric descent and after the landing. As of 2005, Cassini is conducting multiple flybys of Titan and icy satellites. On March 10, 2006, NASA reported that the Cassini probe found evidence of liquid water reservoirs that erupt in geysers on Saturn's moon Enceladus. On July 27, 2006, NASA confirmed the presence of hydrocarbon lakes in Titan's north polar region.
On September 20, 2006, a Cassini probe photograph revealed a previously undiscovered planetary ring, outside the brighter main rings of Saturn and inside the G and E rings. The primary mission ends in 2008 when the spacecraft has completed 74 orbits around the planet.
