As the name suggests, a strong focus of ESA’s Jupiter Icy Moons Explorer (Juice) is to explore the subsurface oceans of Jupiter’s icy moons. But an investigation into how life-friendly worlds form around gas giants would be incomplete without also studying Jupiter's turbulent atmosphere, its enormous magnetic field, and the dusty rings and myriad smaller moons that orbit the planet.
Delve into more detail in the second part of this infographic, which presents the main questions that Juice seeks to answer about these parts of the Jovian 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.
