What spacecraft carried the Huygens probe to Saturn?

The spacecraft that carried the Huygens probe to Saturn was Cassini.

Cassini–Huygens was a joint mission involving NASA, the European Space Agency, and the Italian Space Agency. NASA’s Cassini orbiter carried ESA’s Huygens probe during the seven-year journey to Saturn, arriving in 2004. Cassini then entered orbit around Saturn and became the mission’s long-lived observation platform.

On December 25, 2004, Cassini released Huygens toward Titan, Saturn’s largest moon. Huygens entered Titan’s thick, hazy atmosphere on January 14, 2005, descended by parachute, and landed on the surface. It became the first spacecraft to land on Titan and transmitted atmospheric and surface data back through Cassini to Earth.

The names are easy to confuse because “Cassini–Huygens” describes the combined mission, while Cassini refers specifically to the orbiter and Huygens to the lander. Voyager 2 flew past Saturn but did not carry Huygens; Juno explored Jupiter, and Galileo explored Jupiter and its moons. Cassini continued studying Saturn, its rings, and its moons until its deliberate plunge into Saturn in 2017.
