JUICE – JUpiter ICy moons Explorer – is the first large-class mission in ESA’s Cosmic Vision 2015-2025 programme. Scheduled for launch in 2022, with arrival in the Jovian system in 2029, JUICE will spend three-and-a-half years examining the giant planet’s turbulent atmosphere, enormous magnetosphere, its set of tenuous dark rings and its satellites. It will study the large icy moons Ganymede, Europa and Callisto, which are thought to have oceans of liquid water beneath their icy crusts – perhaps even harbouring habitable environments.
The Jovian system is similar to small-scale star system, whit moons with unique environments and a central object with a composition similar to that of the Sun. This is the main reason why by studying it we can learn about how the Solar System and exoplanetary systems work, how planets are created, and how life can develop under different conditions.
