Engineers in Germany have started building JUICE, the JUpiter ICy moons Explorer. JUICE will launch in the mid-2020s on a tour of Jupiter’s icy moons Europa, Callisto, and Ganymede. The spacecraft will eventually enter orbit around Ganymede and study the moon for 9 months.
Preparations for the December launch of ESA’s CHaracterising ExOPlanet Satellite, CHEOPS, are continuing in Kourou, French Guiana. ESA released pictures of the unpacked CHEOPS spacecraft after it shipped from Spain. The spacecraft will observe known exoplanets as they pass in front of their host stars, which will help scientists determine the exoplanets’ sizes and densities.
