Rocket Technology
Rockets work by a scientific rule called Newton’s third law of motion. … The exhaust pushes the rocket, too. The rocket pushes the exhaust backward. The exhaust makes the rocket move forward..The launch of a spacecraft comprises a period of powered flight during which the vehicle rises above Earth’s atmosphere and accelerates at least to orbital velocity. Powered flight ends when the rocket’s last stage burns out, and the spacecraft separates and continues in free-fall.
