Designing electronic equipment for hostile environments like industry, the automobile, and the military is a major challenge. Topping the list, though, is system design for space. There’s probably no greater hostile environment than outer space. We know this from past experience in designing satellites for deep-space probes and moon shots.
Space isn’t just an open vacuum—it’s also a seriously hazardous place. The temperature extremes are well-known, but the invisible radiation is the major problem. Dealing with that involves finding the electronic parts that can survive such an environment. The solution is radiation-hardened components.
