Imperial College JUICE J-MAG Home Page
JUICE is a European Space Agency (ESA) mission to Jupiter and its Galilean moons.
The JUpiter ICy moons Explorer JUICE will use the Jupiter system as an archetype for gas giants and their icy moons and to assess the habitability of the moons. JUICE will be the first spacecraft to orbit one of the moons, Ganymede. It will provide a unique opportunity to characterise Ganymede’s subsurface ocean. J-MAG will study the interaction between Ganymede’s intrinsic magnetic field and Jupiter’s to help determine the depth and extent of the ocean as well as understand the source of Ganymede’s intrinsic field.
JUICE was selected as the first large-class mission for ESA's Cosmic Vision 2015-2025 programme in May 2012. J-MAG was selected as one of the 11 scientific experiments to be carried aboard JUICE in February 2013. The spacecraft and payload are presently under development.
