Top-down view of the Jupiter Icy Moons Explorere (Juice) in the Large Space Simulator at ESTEC, ahead of environmental testing.
Juice will make detailed observations of Jupiter and its three large ocean-bearing moons – Ganymede, Callisto and Europa – with a suite of remote sensing, geophysical and in situ instruments. The mission will investigate the emergence of habitable worlds around gas giants and the Jupiter system as an archetype for the numerous giant exoplanets now known to orbit other stars.
