Résumé
This white paper briefly describes outstanding questions pertaining to Titan and Enceladus - legacies of the successful Cassini-Huygens mission. We make the case that such questions are not merely specific to these two mysterious systems but have much broader and deeper implications for humakind’s outstanding questions at large of habitability in the Solar System. For these reasons, we recommend the acknowledgement of Titan and Enceladus as priorities for ESA’s Voayage 2050 programme and to combine efforts, in science and technology, with international agencies to launch a dedicated mission to either or both tagets, much like ESA’s key involvement in some of the most successful planetary missions like Cassini-Huygens.
