Liquid rocket propulsion

Liquid rocket propulsion uses liquid propellants stored in tanks and fed into a combustion chamber, where they are ignited to produce high-pressure gases that generate thrust. This technology allows precise control over engine start, stop, and throttle, making it versatile for space missions. The main advantage is efficiency and reusability, as the propellants can be pumped into the engine as needed. Examples include the engines used in the Apollo lunar module and many modern launch vehicles, enabling spacecraft to reach orbit and beyond with reliable, controllable power.
