The European Space Agency's ambitious mission called Jupiter Icy Moons Explorer, or JUICE, was launched on 14 April from French Guiana. Its main objective is to study Jupiter and its three icy moons: Ganymede, Europa, and Callisto.
One of the instruments on board the JUICE spacecraft is called Moons and Jupiter Imaging Spectrometer or MAJIS. It was developed at the Institut d'Astrophysique Spatiale (IAS) which is based in Orsay near Paris.
