Artist's impression of the JUICE space probe together with Jupiter and its four Galilean moons
The JUICE space probe together with Jupiter and its four Galilean moons. Ganymede is shown in cross-section to display its supposed internal structure. You can see a thin blue line marking an ocean of water sandwiched between ice shells, surrounding a core of metal and rock. The small moon to the left is Io, which has no icy armour but does have sulphur geysers. JUICE will not fly to Io.
