Understanding Ganymede

A key focus of ESA's Jupiter Icy Moons Explorer (Juice) will be Ganymede: Jupiter’s largest moon, and an ideal natural laboratory for studying the icy worlds of the Solar System.

Juice will make detailed observations of Jupiter and its three large ocean-bearing moons – Ganymede, Callisto and Europa – with a suite of instruments. The mission will characterise these moons as both planetary objects and possible habitats, explore Jupiter’s complex environment in depth, and study the wider Jupiter system as an archetype for gas giants across the Universe.
