ESA’s Jupiter Icy Moons Explorer, Juice, is set to embark on an eight-year cruise to Jupiter starting April 2023. The mission will investigate the emergence of habitable worlds around gas giants and the Jupiter system as an archetype for the numerous giant planets now known to orbit other stars.
During its tour of the Jupiter system Juice will perform a total of 21 flybys of Callisto, an ancient, cratered world that may harbour a subsurface ocean. Some of the Callisto flybys will also change the angle of Juice’s orbit with respect to Jupiter’s equator, making it possible to investigate the giant planet's polar regions and environment at higher latitudes.
Watch the full sequence of Juice’s journey to, and tour of, Jupiter and its icy moons.
