No, during the delay phase between engine burnout (when the engine runs out of propellant) and its ejection charge (when the parachute deploys), the rocket engine is releasing smoke to help track the rocket without providing any thrust. Most of the smoke you see is produced after the engine burns out.

Why do you need a rocket to go to space?

A rocket is a type of engine that pushes itself forward or upward by producing thrust. Unlike a jet engine, which draws in outside air, a rocket engine uses only the substances carried within it. As a result, a rocket can operate in outer space, where there is almost no air. A rocket can produce more power for its size than any other kind of engine. It can carry people and equipment into space. That is why there is aneed for using rocket to go to spce.
