Juice’s flyby of Ganymede

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 make 12 flybys of Ganymede starting in July 2031, and will eventually become the first spacecraft to orbit another planet’s moon. This video shows Juice performing its first flyby of Ganymede a few hours before Jupiter orbit insertion, with the giant planet visible in the background.

Ganymede is unique in the Solar System in that it is the only moon to have a magnetosphere. Juice will investigate this phenomenon and the moon’s internal magnetic field, and explore how its plasma environment interacts with that of Jupiter. Juice will also study Ganymede’s atmosphere, surface, subsurface, interior and internal ocean, investigating the moon as not only a planetary object but also a possible habitat.
