the F-1 rocket engine

The F-1 engine was a powerful rocket engine used in the Saturn V rocket to send astronauts to the Moon. It operates by burning liquid oxygen and kerosene fuel at high pressure, producing an immense amount of hot gases that blast out of the nozzle, pushing the rocket upward through Newton's third law. With over 1.5 million pounds of thrust, it was one of the most powerful single-chamber liquid-fuel rocket engines ever built. The F-1's reliability and strength made it essential for overcoming Earth's gravity and enabling lunar travel during the Apollo program.
