ESA Science & Technology - TandEM/TSSM
The Titan and Enceladus Mission (TandEM), an ambitious scientific mission to study the Saturnian system with particular emphasis on the moons Titan and Enceladus, was selected in October 2007 as a candidate mission within the ESA Cosmic Vision plan. In February 2009, TandEM exited the Cosmic Vision programme when ESA and NASA chose EJSM-Laplace as the L-class outer Solar System mission candidate.
