RAD charged particle flux observations during ~7 months of cruise included contributions from 5 solar energetic particle events. The inset compares the particle flux observed by RAD to that observed by instruments on the ACE spacecraft. The MSL spacecraft structure (backshell, heatshield, etc.) provided significant shielding from deep space radiation, significantly reducing the particle flux compared to ACE.
