Juice rotation in the clean room

Rotating Juice in the clean room at ESA's technical heart in the Netherlands before transfer in the Large Space Simulator.

Juice will undergo environmental testing in ESTEC’s Large Space Simulator to replicate the extreme heating and cooling cycles that the spacecraft will experience on its way to Jupiter.

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.
