Spacecraft propulsion

Spacecraft propulsion refers to the methods and technologies used to generate thrust in order to move and control spacecraft in space. Unlike vehicles on Earth, which utilize friction and atmospheric forces to aid their movement, spacecraft operate in the vacuum of space where traditional propulsion methods (like wheels and brakes) are ineffective. Therefore, spacecraft propulsion systems must rely on different principles to maneuver and navigate in the absence of air and against the gravitational pull of celestial bodies.
