Description
The Jovian radiation environment presents a severe threat to spacecraft operation due to the large magnetic field of Jupiter allowing it to stably trap charged particles, especially electrons, at higher energies and over greater distances than found in Earth’s Van Allen belts. As part of the ESA JUICE mission, an assessment is on-going into the different hardening and alternative radiation mitigation strategies which may be implemented to reduce the threat from ionising and non-ionising cumulative dose, and spacecraft charging. In this paper we summarise the studies and SPENVIS- and Geant4-based software tools developed and being applied as part of the ESA JORE2M2 and GREET Projects to predict the radiation environment around Europa, Ganymede and Callisto, and to assess the performance of shielding against that environment.
