Thrust Vector Control (TVC) is a technology used in rockets and spacecraft to steer and stabilize their flight. By changing the direction of the engine's thrust, TVC allows for precise maneuvering in space or during atmospheric flight. This is crucial for achieving desired trajectories and ensuring safe landings. TVC can be achieved through various methods, such as gimbaling the engine or using movable nozzles. This technology is employed in many modern launch vehicles, including those developed by NASA and SpaceX, enhancing their performance and control during missions.
