Enceladus, the sixth largest moon of Saturn, was chosen as "the main target" in the space plans of the European Agency for the middle of this century. The European Space Agency (ESA) is planning a huge mission as part of the Voyager 2050 program, and the first destination is already on the agenda.

Beneath its icy surface lies a fascinating secret: a vast global ocean that surrounds the entire moon. The existence of this subsurface ocean makes Enceladu one of the most fascinating bodies in the Solar System, and a leading candidate for extraterrestrial life.
