's Laplace-P. The JMO objective was to undertake detailed ''in situ'' studies of the

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 a payload up to 10 kg, equivalent to 2 to 3 scientific instruments. In order to conduct observations never made before, the spacecraft would have carried an X-ray imaging spectroscope, featuring different wavelengths from instruments onboard NASA's Juno probe. In November 2013, Japan's JAXA scientists stated that ″it is difficult for JAXA to launch the outer planet mission by itself to meet the time constraint for cooperative observation with JUICE. Therefore, direct collaboration with European groups/team should be necessary for Japanese scientists to participate in this attractive Jupiter system mission.″ The outcome was the selection of four Japanese instrument development teams for 4 of the 10

(JUICE) mission instruments.
