Which probe landed on Saturn's moon Titan in January 2005? The Huygens probe landed on Titan in January 2005.

Huygens was the lander component of the joint Cassini–Huygens mission, built and operated by the European Space Agency with NASA and the Italian Space Agency as partners. It separated from NASA's Cassini orbiter on 25 December 2004 and began its final approach to Titan.

On 14 January 2005, Huygens entered Titan's thick atmosphere under parachutes and successfully touched down near the Adiri region. It became the first spacecraft to land on Titan and the first to land on a world in the outer Solar System. The probe measured Titan's atmosphere, winds, surface conditions, and chemistry during its descent and after landing.

Huygens was not an orbiter: Cassini remained in space and relayed Huygens's data to Earth. Philae landed on a comet, Viking 1 landed on Mars, and Galileo was an orbiter and atmospheric probe for Jupiter. Huygens was named for Dutch astronomer Christiaan Huygens, who discovered Titan in 1655.
