The Huygens Probe was part of the joint ESA-NASA Cassini-Huygens mission to Saturn and its moon, Titan. Huygens was carried to the Saturnian system aboard the Cassini spacecraft, which continued to study Saturn after launching Huygens into the dense atmosphere of Titan. The main Huygens mission, a parachute descent through Titan's atmosphere, revealed a dense cloud atmosphere at the surface, about 20 kilometers thick, and a muddy landing sight featuring chunks of water ice swimming in a haze of methane. Titan's weather is believed to feature torrential downpours and flash flooding, interspersed with decades or centuries of drought; surface features include boulder fields, sand or clay swamps and numerous hydrocarbon lakes and seas.
