Cassini/Huygens is an ESA/NASA mission to the Saturnian system. Carried on NASA's Cassini Saturn orbiter, ESA's Huygens probe will explore the atmosphere of Titan, Saturn's largest moon. A few months after going into orbit around Saturn, Cassini will release Huygens for its entry and descent through Titan's atmosphere to the surface. Cassini will go on to make many close fly-bys to continue the global exploration of Titan during its nominal four-year mission.
