Cassini was the orbiter that carried the Huygens lander to Saturn’s moon Titan.
The Cassini–Huygens mission launched in October 1997 as a collaboration among NASA, the European Space Agency and the Italian Space Agency. Cassini entered orbit around Saturn in 2004 after gravity-assist flybys of Venus, Earth and Jupiter. It then studied Saturn, its rings and its moons for more than thirteen years.
Huygens separated from Cassini and descended through Titan’s thick atmosphere on 14 January 2005. It became the first spacecraft to land on a world in the outer Solar System and transmitted measurements and images from Titan’s surface.
Cassini was named for Giovanni Domenico Cassini, the astronomer who discovered several Saturnian moons and the major gap in Saturn’s rings. Galileo and Juno were NASA missions to Jupiter, while Magellan mapped Venus.
