Cassini-Huygens to Saturn
Launch: October 15,1997
A joint endeavor of NASA, the European Space Agency and the Italian Space Agency, Cassini arrived at Saturn in June 2004 carrying a record number of 12 instruments. The mission is an intensive study of Saturn's rings, its moons and magnetosphere. Cassini released the Huygens probe towards Saturn's largest moon, Titan and the probe successfully landed on the moon's surface in January 2005.
Titan and Enceladus Mission
Primary goals are to understand the atmosphere, surface and interior, to determine the chemistry, and to derive constraints on the origin and evolution of Titan and of the saturnian system as a whole, with an emphasis on Enceladus.
Note: Following the joint ESA-NASA decision in February 2009 to further pursue the Europa Jupiter System Mission (EJSM), the studies concerning the TandEM mission concept within ESA have been terminated.
