This Is Rocket Science: True Stories of the Risk-taking Scientists who Figure Out Ways to Explore Beyond Earth
Gloria Skurzynski
Thrust in a rocket depends on the rate at which the mass of the burning fuel inside the rocket is expelled through the nozzle at the end of the rocket and the speed at which it escapes. The force of the extremely hot gases escaping through the nozzle accelerates the rocket. The heavier the rocket, the more thrust/force will be needed to move it. If a rocket weighs a million pounds and only a million pounds of thrust is produced, the rocket won’t move. To launch it off the ground requires a thrust greater than a million pounds so it can overcome gravity and air resistance. To increase the thrust level requires burning more fuel, using a higher-energy fuel, or both.
