Preliminary Radiation Test Result for Space-Ready Qualification of Lunar Micro Rover

Abstract

This paper presents the radiation testing results on several non-space-ready commercial-off-the-shelf (COTS) devices to validate the space readiness of a lunar rover flight model. These COTS candidates are bombarded by a proton beam at a high energy level, simulating the lunar surface radiation conditions under solar flares. We have determined that the tested devices experience a minimal number of minor single events, when each hardware receives beyond the actual mission dosage. Furthermore, the system recovery from a single event is confirmed throughout the test. The result culminates a step further to the qualification of a launch-ready vehicle.
