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.

Chemical thrusters that use fuel (like hydrazine) and often an oxidizer to create hot, high-velocity exhaust for more powerful maneuvers. 2. Maritime: Ship Maneuverability

A newer, quieter design where the electric motor is built into a ring around the propeller blades, reducing vibration and increasing efficiency.

Propellers housed in pods that can rotate 360 degrees, allowing the ship to steer without a traditional rudder.

Small thrusters used for attitude control (orienting the ship) and station-keeping (maintaining a specific orbit).
