6-666: Jupiter Ganymede Orbiter ( JGO ) was a part of the international Europa Jupiter System Mission (EJSM). It was a proposed orbiter by the ESA slated for lift-off in 2020. Plans for the mission include detailed studies of Jupiter's moons, Ganymede and Callisto , as well as the Jovian magnetosphere . It was superseded by the Jupiter Icy Moons Explorer in April 2012.

12-495: A probe to study the icy satellites of the outer Solar System under the title Outer Planet Flagship Mission . Two primary candidate missions were considered under the study: EJSM and Titan Saturn System Mission (TSSM), also known under the ESA designation TandEM. In February 2009, it was announced that NASA/ESA had given EJSM priority ahead of the TSSM. The ESA contribution still faced funding competition from two other missions,

Europa Jupiter System Mission The Europa Jupiter System Mission – Laplace ( EJSM-Laplace ) was a proposed joint NASA / ESA uncrewed space mission slated to launch around 2020 for the in-depth exploration of Jupiter's moons with a focus on Europa , Ganymede and Jupiter's magnetosphere . The mission would have comprised at least two independent elements, NASA's Jupiter Europa Orbiter (JEO) and ESA's Jupiter Ganymede Orbiter (JGO), to perform coordinated studies of
24-684: The Laser Interferometer Space Antenna (LISA) and the International X-ray Observatory (IXO), which is why NASA kept a contingency plan of sending its part of the mission as a stand-alone project. The most distinctive feature of the EJSM/Laplace-study, was the proposed collaboration with multiple orbiters and landers: The baseline EJSM architecture consisted of JEO and JGO, which were proposed to be launched in 2020 and explore
30-497: The Jovian system. The Japan Aerospace Exploration Agency ( JAXA ) and the Roscosmos (Russian Space Agency) had expressed their interest in contributing to EJSM-Laplace, although no deals had been finalized. JEO was estimated to cost US$ 4.7 billion, while ESA would spend US$ 1.0 billion (€710 million) on JGO. In April 2011, European Space Agency (ESA) stated that it seemed unlikely that a joint US–European mission will happen in
36-704: The early 2020s given NASA's budget, so ESA continued with its initiative, called the Jupiter Icy Moons Explorer (JUICE) that will be based on the JGO design. Selection of JUICE for the L1 launch slot of ESA's Cosmic Vision science programme was announced on 2 May 2012. JUICE was launched on 14 April 2023. Later, in June 2015, NASA approved the Europa Clipper , which was launched on October 14th, 2024. In February 2008, NASA and ESA began joint investigations into sending
