ESA's Jupiter Icy Moons Explorer (JUICE) successfully passed the ground segment requirements review, demonstrating that the ground teams that will operate JUICE and its suite of science instruments meet all the necessary requirements. Following its scheduled launch in 2022, JUICE is going on a 7.5-year long journey through the Solar System before arriving at Jupiter in 2029, where it will examine the planet and its icy moons Ganymede, Europa and Callisto. Bearing ten different state-of-the-art instruments, e.g. an ice-penetrating radar, JUICE is well-equipped to investigate whether oceans of liquid water are concealed beneath the moons’ icy crusts. Contributors to the ground segment of JUICE are the Space Operations Centre in Darmstadt, Germany, and Science Operations Centre near Madrid, Spain.
