The SpaceX Raptor is a powerful rocket engine designed for use in the Starship spacecraft and the Super Heavy booster. It operates on a full-flow staged combustion cycle, which improves efficiency and performance. The Raptor engine uses liquid methane and liquid oxygen as propellants, allowing for potential refueling on Mars. Each Raptor engine produces over 230 metric tons of thrust, making it one of the most powerful rocket engines ever built. Its design focuses on reusability, which is a key aspect of SpaceX's mission to reduce the cost of space travel and enable human exploration of other planets.
