摘要

NASA and ESA have embarked on a joint study of a Europa Jupiter System Mission (EJSM) with orbiters developed by NASA, ESA, and possibly JAXA (Japan Aerospace Exploration Agency) to be launched no earlier than 2020. The NASA element of the joint endeavor, Jupiter Europa Orbiter (JEO), would be a nuclear-powered spacecraft designed to explore Europa and investigate its habitability. The proposed JEO includes a single orbiter flight system that travels to Jupiter by means of a multiple-gravity-assist trajectory. It is designed to function alone or in conjunction with ESA's Jupiter Ganymede Orbiter (JGO). The mission would conduct 30 months of Jupiter system science plus a comprehensive Europa orbit phase of 9 month period; thus addressing a very important subset of the EJSM science objectives. This paper focuses on the radiation challenges and risk mitigation for the proposed NASA-led JEO mission and describes a system-level radiation-hardened-by-design approach to mitigate pervasive mission and system level impacts.
