// ORBITAL LOGISTICS AND PROPULSION TERM
Rocket Engine
A rocket engine is a type of jet engine that carries both its fuel and oxidizer, allowing it to operate in space where there's no air. It generates thrust by expelling hot gases at high speed.

TECHNICAL DEFINITION
A rocket engine is a reaction engine that generates thrust by expelling high-velocity exhaust fluid, typically produced by the combustion of propellants carried entirely onboard, enabling operation in both atmospheric and vacuum environments.
BACKGROUND
