Circuit
In space and astronautical engineering, a circuit refers to a closed loop of conductive material that allows the flow of electric current. Circuits are essential components of spacecraft and satellites, as they provide power to the various systems and instruments on board. There are two main types of circuits used in space engineering: analog and digital. Analog circuits are used for continuous signals, such as those from sensors, while digital circuits are used for discrete signals, such as those from computers. Circuits can be designed using various materials, including copper, aluminum, and gold, depending on the specific requirements of the mission. The design of circuits must take into account the harsh conditions of space, including extreme temperatures, radiation, and vacuum.
