NASA is collaborating with the European Space Agency (ESA) on this ESA-led mission to Ganymede and the Jupiter system. ESA plans to launch the mission in 2022 for arrival at Jupiter in 2030. It has a tentative model payload of 11 scientific instruments. The NASA contribution consists of three separate projects: one full instrument, Ultra Violet Spectrometer; two sensors for the Particle Environment Package suite of instruments; and the transmitter and receiver hardware for the Radar for Icy Moon Exploration instrument.
