The European Space Agency is to mount a billion-euro mission to Jupiter and its icy moons, launching in 2022.
The probe, called Juice, has just been approved at a meeting of member state delegations in Paris.
It would be built in time for a launch in 2022, although it would be a further eight years before it reached the Jovian system.
The mission has emerged from a five-year-long competition to find the next "large class" space venture in Europe.
