A two-stage rocket is a type of launch vehicle that uses two separate stages to reach space. Each stage has its own engines and fuel. The first stage provides the initial thrust to lift the rocket off the ground, while the second stage ignites after the first stage has completed its burn and is jettisoned. This design allows for more efficient use of fuel and weight, as the rocket sheds parts that are no longer needed. The two-stage design is commonly used in various space missions, including those by organizations like NASA and SpaceX. By separating the stages, the rocket can achieve higher speeds and altitudes, making it capable of delivering payloads, such as satellites or crewed spacecraft, into orbit around the Earth or beyond.
