Immunity

In space and astronautical engineering, immunity refers to the ability of a spacecraft or its components to resist and tolerate the harsh space environment, including radiation, extreme temperatures, vacuum, and micrometeoroids. Immunity is a critical factor in the design and operation of spacecraft, as the failure of a single component can jeopardize the entire mission. Engineers use various techniques to enhance the immunity of spacecraft, such as shielding, redundancy, and fault tolerance. The immunity of a spacecraft is also tested through simulations and ground-based experiments to ensure its reliability and safety in space.
