JUICE is scheduled to perform 35 Jovian moon flybys, but the mission will end with the spacecraft settling into a circular orbit around Ganymede, where it will work for an estimated six months and come as close as 311 miles (500 km) to its surface. By doing so, “Juice will be the first spacecraft to ever orbit a moon in the outer Solar System,” ESA claims. The space agency chose a good target, as Ganymede, the biggest moon in the solar system, is the only known moon to exhibit its own magnetic field, which causes it to interact with the Jovian environment in unique ways.
