MISSION NEWS AS OF TUESDAY 16 JANUARY 2018
Out of Jupiter’s nearly 70 moons, the four Galilean satellites—Io, Europa, Ganymede and Callisto—stand out as distinctive planetary worlds in their own right. They contain more than 99% of the mass orbiting around Jupiter, are among the largest satellites in the Solar System, and have remarkable geologies. JUICE will study the three icy bodies—Europa, Ganymede and Callisto—to find out more about these potentially habitable environments.
- JUICE GROUND CONTROL GETS GREEN LIGHT TO START DEVELOPMENT OF JUPITER
ESA’s Jupiter Icy Moons Explorer – JUICE – passed an important milestone, the ground segment requirements review, with flying colours, demonstrating that the teams are on track in the preparation of the spacecraft operations needed to achieve the mission’s ambitious science goals.

MYSTERIOUS MAGNETIC FIELD
One of Ganymede’s most remarkable features is its intrinsic magnetic field, discovered by the Galileo mission. No other moon in the Solar System is known to have one, and only two other solid bodies (Mercury and the Earth) generate magnetic dipole fields. Ganymede’s miniature magnetosphere lies within Jupiter’s much larger magnetosphere, with complex interactions happening between the two. JUICE aims to study these interactions in detail. This includes looking into how particles in the near-Ganymede space environment affect the composition of the moon’s surface, how auroras develop on the satellite, and how Ganymede’s magnetic field influences auroras on Jupiter. To do this, some of the mission’s instruments will measure the moon’s magnetic field, both its intrinsic component and that induced by Jupiter. Other instruments will characterise the plasma environment around the moon, studying the particles in it, and will investigate the outer layers of the moon’s thin atmosphere
+ JUICE MISSION SCIENCE
Planned for launch in 2022 and arrival at Jupiter in 2029, JUICE will spend three and a half years examining the giant planet and its environment, in particular investigating the Galilean moons Ganymede, Europa and Callisto.
