Thrusters

Thrusters are a type of propulsion system used primarily on spacecraft, rockets, and some underwater vehicles. They generate controlled force by expelling mass—such as gases or liquids—at high speed through a nozzle. This expulsion produces a reaction force that propels the vehicle in the opposite direction, following Newton's third law. Thrusters allow precise adjustments in position and orientation, enabling spacecraft to navigate, stabilize, and perform maneuvers in space or underwater environments efficiently. They vary in size and power depending on the application, from small thrusters for fine adjustments to powerful engines for major propulsion.
