The European Space Agency is setting a course for Jupiter for its next major mission, named JUICE (JUpiter ICy moon Explorer).
Jupiter is more than eleven times larger than Earth but is mainly made of gas. During its three and a half year mission, which blasts off in 2022, JUICE will travel around the giant planet, studying its atmosphere and three of its planet-sized satellites: Ganymede, Europa, and Callisto.
The mission will seek to confirm the hunch that the moons are hiding habitable zones beneath their icy crusts.
