How is a space shuttle being launched an example of newton's third law?

A space shuttle launch exemplifies Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. As the shuttle's engines ignite, they expel gas downwards at high speed, creating a powerful thrust. This downward force generates an equal and opposite reaction that propels the shuttle upwards into space. Thus, the action of the engines pushing down results in the reaction of the shuttle moving up.
