Active
In space and astronautical engineering, active refers to a system or device that requires an external power source to operate. Active systems are commonly used in spacecraft and satellites to perform various functions such as communication, propulsion, and scientific research. Examples of active systems include solar panels, electric thrusters, and scientific instruments that require power to operate. Active systems are essential for the success of space missions as they provide the necessary power to perform critical functions in space. Without active systems, spacecraft and satellites would not be able to operate in the harsh environment of space.
