Spacecraft control is the field of study that deals with the design and implementation of systems and techniques for controlling the motion and orientation of spacecraft in space. This includes controlling the propulsion systems, navigation systems, attitude control systems, and other subsystems of the spacecraft to achieve desired trajectory, orientation, and stability in space. The goal of spacecraft control is to ensure safe and efficient operation of spacecraft during various phases of a mission, including launch, orbit insertion, attitude adjustment, and maneuvering for scientific observations or communication purposes. This field involves a wide range of disciplines, including aerospace engineering, control theory, computer science, and robotics.
