Thanks Newton, first steps
Understanding how Spacecraft Propulsion works is easier than you think. The mechanism is based on Newton´s principle "to every action there is an equal and opposite reaction." In a rocket engine, hot exhaust gas is produced through the combustion of a fuel with an oxidizer. The hot exhaust gas flows through the rocket nozzle and is accelerated to the rear of the rocket. In re-action, a thrusting force is produced on the engine mount. The thrust accelerates the rocket as described by Newton's second law of motion.
