The partnership for the Europa Jupiter System Mission has since ended, but NASA will continue to contribute the European mission with hardware and an instrument. The "Europa Clipper" is a mission proposed to NASA to focus on studying Jupiter's moon Europa. In March 2013, funds were authorized for "pre-formulation and/or formulation activities for a mission that meets the science goals outlined for the Jupiter Europa mission in the most recent planetary decadal survey". The proposed mission would be set to launch in the early 2020s and
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
