ESA’s Jupiter Icy Moons Explorer, Juice, being installed on a ‘multi-purpose trolley’ in the Rosetta clean room at the European Space Research and Technology Centre, ESTEC in the Netherlands on 30 April. The multi-purpose trolley allows the spacecraft to be rotated and titled, providing better access to the engineers for integration operations and preparation for testing, and in general to facilitate the work on the different sides of the spacecraft. The trolley is made of non-magnetic material, to comply to the strict magnetic cleanliness requirements of the spacecraft.

Once in the Jovian system the mission will spend at least three years making detailed observations of the giant gaseous planet Jupiter and its three large ocean-bearing moons: Ganymede, Callisto and Europa.
