Jupiter Europa Orbiter

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]

Not to be confused with Jovian Europa Orbiter.
