rocket propulsion
Reactive thrust system
Rocket propulsion is the method of generating thrust by expelling mass at high velocity, typically through combustion of fuel and oxidizer.
Unlike jet engines, rockets carry their own oxidizer and can operate in the vacuum of space.
The Saturn V used liquid rocket propulsion to reach the moon.
The principle applies whether the propellant is solid, liquid, or even cold gas.
