Jupiter Icy Moons Explorer (JUICE)
Artist's impression of the European Space Agency's Jupiter Icy Moons Explorer (JUICE) mission, scheduled to launch in 2022. In this view, which is not to scale, Ganymede is shown in the foreground, Callisto to the far right, and Europa center-right. Volcanically active moon Io is also shown, at left. The moons were imaged by NASA’s Galileo spacecraft; Jupiter is seen here with a vivid aurora, captured by the Hubble Space Telescope.
