A rocket is a vehicle designed to travel into space. It works by burning fuel to create a powerful thrust that pushes it upward. Rockets are used for various purposes, including launching satellites, sending astronauts to the International Space Station, and exploring other planets. They are an essential part of modern space exploration. The design of a rocket includes several key components, such as the propellant, which is the fuel and oxidizer that produce thrust, and the payload, which is the cargo the rocket carries, like satellites or scientific instruments. Famous rockets include the Saturn V, which took astronauts to the Moon, and the SpaceX Falcon 9, known for its reusable technology.
