As a part of the defunct Europa Jupiter System Mission – Laplace (EJSM/Laplace), the Jupiter Europa Orbiter (JEO) was a proposed orbiterprobe slated for lift-off in 2020 and planned for detailed studies of Jupiter's moonsEuropa and Io as well as the Jovian magnetosphere.[1] Its main goal would have been to look for evidence of a possible subsurface ocean.[2]
In June 2015, a more economical mission, the Europa Multiple-Flyby Mission (Europa Clipper) was approved by NASA and entered the formulation stage.[3] While orbiters like the JEO would be in the $2-$4B range, a multi-flyby spacecraft like the Europa clipper is estimated to cost much less.[4]
