Transverse propulsion devices built into the front or back of a ship's hull to move the vessel sideways for easier docking.
In space, thrusters are essential for maneuvering because there is no atmosphere to "push" against. They work based on Newton's third law—ejecting mass in one direction to move the craft in the opposite direction. T_hrustrar
Small thrusters used for attitude control (orienting the ship) and station-keeping (maintaining a specific orbit). Transverse propulsion devices built into the front or
