JUICE Mission Set to Launch for Exploration of Jupiter and Its Moons.

Europe's first-ever Jupiter mission, the Jupiter Icy Moons Explorer probe (JUICE), is set to launch on April 13 atop an Ariane 5 rocket from Europe's Spaceport in French Guiana. JUICE will conduct a series of flybys of three of Jupiter's four big Galilean moons — Ganymede, Europa, and Callisto, all of which are thought to possess oceans of liquid water beneath their icy shells. JUICE will be the first probe ever to orbit a moon other than that of Earth. NASA's Europa Clipper, which will focus on Europa, is scheduled to lift off in October 2024.
