Description
The space radiation environment can lead to extremely harsh operating conditions for on-board electronic box and systems. Radiation accelerates the aging of the electronic parts and material and can lead to a degradation of electrical performance; it can also create transient phenomena on parts. The characteristics of the radiation environment are highly dependent on the type of mission (date, duration and orbit). In this lecture, the three components of the space radiation environment are reviewed: particles trapped by planetary magnetospheres in “belts”, solar particles and Galactic Cosmic Rays. Then, models of these environments are presented. Finally, after a quick overview of the interactions of radiative particles with a spacecraft materials and electronic devices, radiation environment and effects within a spacecraft are presented.
