Rocket technology involves the design and development of vehicles that use controlled explosions to propel themselves into space. These vehicles, known as rockets, rely on the principles of thrust and aerodynamics to overcome Earth's gravity. They typically use liquid or solid fuels that burn rapidly, creating a high-speed exhaust that pushes the rocket upward. The key components of a rocket include the propulsion system, which generates thrust, and the payload, which is the cargo or instruments carried into space. Rockets are essential for various missions, including launching satellites, sending astronauts to the International Space Station, and exploring other planets.
