Sensors used in spacecraft are designed to withstand the harsh conditions of space, including radiation from cosmic rays, ultraviolet light, and X-rays. To protect electronics, they are 'radiation hardened' and often shielded, utilizing larger components in microchips and instrumentation to enhance durability. Techniques for radiation hardening include specific design choices and material selections that mitigate damage from high-energy particles. Notable examples of radiation-hardened computers include the RAD750 and RAD6000, which are specifically engineered for space applications. Understanding these technologies is crucial for the continued success of space missions.
