Description
ReTiMo is a mission concept of a CubeSat nanosatellite equipped with novel sensors and instruments in order to characterize in near-real time Space Weather threats to satellites that are becoming part of the critical infrastructure in modern life. ReTiMo will achieve this by measuring scientific parameters relating to Space Weather conditions, as well as engineering parameters that quantify the degradation and anomalous behavior of spacecraft hardware caused by Space Weather. In particular, ReTiMo will provide near-real time information on Single Event Effects on electronics of various damage thresholds, together with fluxes of damaging energetic protons that can be either trapped in the radiation belts or impinging upon near Earth space from the Sun during large solar eruptions. ReTiMo will also measure spacecraft charging due to auroral precipitating electrons, field-aligned currents that correlate with enhanced surface charging, and the degradation of solar cell parameters caused by energetic particles. In this talk, we will present the instrumentation, measurement principles and mission parameters of the ReTiMo mission concept, and we will discuss aspects of mission optimization, complementarity with existing measurements and applicability to various orbits.
