Abstract

The variability of space radiation hazard towards the low-Earth orbit (LEO) spacecraft is reviewed. Three major space radiations, i.e. galactic cosmic rays (GCRs), solar proton events (SPEs), and trapped particles form potential hazards for LEO spacecraft. We focused on trapped particle hazard due to its major role for LEO spacecraft anomaly. We examined the trapped particle variability distribution in solar cycle 23. The year of 2000 and 2008 were chosen to best represent solar maximum and minimum in that cycle. Monthly average particles fluxes plotted in both years showed a quite similar value for all peak values during solar maximum. We also examined events of LEO satellites anomaly for both years by using space weather and geomagnetic parameters as well as the distribution of particles fluxes during those events. Analysis showed that all parameter indicators in the year 2000 were in a critical condition, whereas for the year of 2008, the anomaly occurs was in a normal state.
