Juice antenna closeup

Close up view of the Jupiter Icy Moons Explorer (Juice) high-gain antenna, which will be used to communicate data between the spacecraft and ground stations on Earth.

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.
