Abstract：Space radiation is a major concern for the safety of robotic and human exploration both in the near-Earth environment and towards deep space and other planetary bodies such as the Moon and Mars. It is therefore important to characterize and predict the fluxes of the major sources of energetic particle radiation in the heliosphere including solar energetic particles (SEPs) and Galactic cosmic rays (GCRs). This involves a good understanding of the GCR modulation process and the SEP/GCR transport mechanisms. Moreover, the space weather effects of these particles in the vicinity of the Moon or Mars are different from that in deep space due to the specific planetary environment. In this talk, we will briefly review the current understanding of the deep space radiation environment based on the recent planetary missions and the state-of-the-art modeling efforts and address the space radiation related challenges of future Lunar and Martian Exploration programs.
