Abstract:
Statement of the Problem: JUICE, the L-class mission of ESA to explore the Jupiter system will deliver chemical measurements of the Jupiter satellites exospheres, the icy moons Europa, Ganymede and Callisto. One of the instruments in the PEP consortium employed on the mission will the neutral gas mass spectrometer as part of the particle consortium (PEP). We develop prototypes of the instrument to test against the physical and environmental conditions expected in the Jupiter environment, and measurements near these moons. The exospheres of the icy moons are populated by material originating directly from the moons’ surfaces, thus NIM measurements can be inverted to derive the chemical composition of the surface. By studying the composition of all three icy moons we will also get crucial information on the evolution of these objects with time, since they started from the same chemical inventory. We started unique laboratory experiments simulating the icy surfaces of these moons and their response to particle radiation in forming their exospheres; in parallel we develop necessary shielding against the high energy radiation to protect the instruments and theoretical models of the atmospheres of these moons, both in preparation of the science phase of this mission.
