ESA’s Jupiter Icy Moons Explorer (Juice) will make detailed observations of the giant gas planet and its three large ocean-bearing moons – Callisto, Europa and in particular Ganymede. This graphic shows the main mission milestones, from arrival at the launch site in French Guiana in February 2023 to arrival at Ganymede in December 2034.
On its journey to Jupiter, Juice will make a series of flybys of Earth, the Earth-Moon system and Venus to set it on course for its July 2031 rendezvous in the Jovian system. Once Juice has arrived at Jupiter, it will make 35 flybys of the icy moons before going into orbit around Ganymede to make more detailed observations.
Watch the full sequence of Juice’s journey to, and tour of, Jupiter and its icy moons.
