MPhil student Holly Snell completes her MPhil dissertation

Outer space is a hazardous environment for satellites as they are continuously exposed to harsh space radiation in the form of cosmic rays and high-energy electrically charged particles (protons, electrons and alpha particles). Mission-critical electronic components are especially susceptible to space radiation as high-velocity charged particle impacts on molecular-sized circuitry can cause significant device upsets or permanent damage, compromising a satellite’s functional integrity. In her dissertation, Snell investigated the use of various software tools to model the radiation environment in Earth orbit, to provide guidelines for using the space radiation models found on the Space ENVironment Information System (SPENVIS) for radiation modelling during mission planning. Snell also presented her work at the International Astronautical Congress in Adelaide, Australia, in October 2017.
