As space missions venture ever further afield, spacecraft will inevitably be exposed to greater amounts of cosmic radiation that can damage or even destroy their onboard electronics. Cosmic radiation is ionizing radiation made up of a mixture of heavy ions and cosmic rays (high-energy protons, electron and atomic nuclei).
