The JUICE Spacecraft System Design

In April 2023, the European Space Agency (ESA) launched its largest interplanetary space probe to date: the Jupiter Icy Moons Explorer (JUICE). Scheduled to arrive at Jupiter in July 2031, JUICE will conduct a four-year investigation of the planet and its Galilean moons, concluding with an orbital phase and final impact on Ganymede. This paper summarizes the mission drivers and key system and subsystems design. Instrument accommodation, verification strategy, launch and commissioning activities, and the principal performance characteristics of the spacecraft and payload are also outlined.
