Jupiter Magnetospheric Orbiter the orbiter was proposed for a lift-off in 2020 together with ESA's Jupiter Ganymede Orbiter (JGO) from which it would undock upon its arrival at Jupiter in 2025/2026. However, the EJSM collaboration was disbanded and NASA renamed its initiative with Europa Multiple-Flyby Mission, ESA's Jupiter Icy Moon Explorer, and Roscosmos's Laplace-P. The JMO objective was to undertake detailed "in situ" studies of the magnetosphere of Jupiter as a template for an astrophysical magnetised disk for "3-point" investigations of the Jupiter system via synergistic observations with other orbiters. The size and weight of the JMO would have been limited to carry
Exploration of Mars years beyond their specification. As of 10 June 2018, two rovers were on the surface of Mars beaming signals back to Earth ("Opportunity" of the Mars Exploration Rover mission and "Curiosity" of the Mars Science Laboratory mission), with six orbiters surveying the planet: "Mars Odyssey", "Mars Express", "Mars Reconnaissance Orbiter", "Mars Orbiter Mission", MAVEN, and the Trace Gas Orbiter, which have contributed massive amounts of information about Mars. The stationary lander "InSight" is investigating the deep interior of Mars. No sample return missions have been attempted for Mars and an attempted return mission for Mars' moon Phobos ("Fobos-Grunt") failed. On
