On June 30, 2004 (PDT), as mission controllers at NASA’s Jet Propulsion Laboratory held their collective breath, the international Cassini-Huygens mission successfully arrived in orbit around Saturn. NASA’s Cassini spacecraft delivered the European Space Agency’s Huygens probe to Titan in early 2005. Cassini completed its four-year primary mission in 2008 and went on to perform dozens more flybys of Titan, Enceladus and Saturn's other icy moons through its 10th anniversary in 2014. The mission may continue through 2017.
