The Jupiter Icy Moons Explorer (JUICE) is an interplanetary spacecraft that was launched on 14 April 2023 by the European Space Agency (ESA) with Airbus Defence and Space as the main contractor. The mission is planned to study Ganymede, Callisto, and Europa, three of Jupiter's Galilean moons. They are thought to have significant bodies of liquid water beneath their icy surfaces which would make them potentially habitable environments. The mission does not focus on volcanically active Io, a non-icy moon. The spacecraft launched on 14 April 2023 at 12:14 UTC[3] and will reach Jupiter in July 2031 after four gravity assists and eight years of travel. In December 2034, the spacecraft will enter orbit around Ganymede for its close-up science mission,[6] becoming the first spacecraft to orbit a moon other than the Moon of Earth. The selection of this mission for the L1 launch slot of ESA's Cosmic Vision science programme was announced on 2 May 2012. Its period of operations will overlap with NASA's NAME_1 mission, launching in 2024.
