The simplest form, using pressurized inert gas (like nitrogen) released through a nozzle. They are safe but low-power.

Highly efficient systems that use electricity to accelerate ions. While they provide very low thrust, they can run for years, making them ideal for long-duration deep-space missions. T_hrustrar

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. The simplest form, using pressurized inert gas (like
