This expulsion generates a rearward force. The external pressure changes, but the internal physics remains the driving force; the rocket moves because it throws mass behind it, regardless of the surrounding environment.
Rocket Thrust Force Reaction Pair: Action and Reaction in Motion
Airplanes rely on wings interacting with air molecules to generate lift, but rockets are different. This reaction produces a massive amount of hot, high-pressure gas.
This interaction occurs internally; the rocket does not need to push against anything external like air or ground. The mass of these gases times their velocity creates the momentum that must be balanced by an equal momentum in the rocket, propelling it upward.

The Core Mechanism: Action and Reaction Newton's Third Law operates in distinct pairs. From Atmosphere to Vacuum A common misconception is that rocket engines require air to "push" against.
