As a part of the defunct Europa Jupiter System Mission – Laplace (EJSM/Laplace), the Jupiter Europa Orbiter (JEO) was a proposed orbiter probe slated for lift-off in 2020 and planned for detailed studies of Jupiter's moons Europa 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]
