    Falcon Heavy (FH), previously known as the Falcon 9 Heavy, is a spaceflight launch system being designed and manufactured by SpaceX. Both stages of the two-stage-to-orbit vehicle use liquid oxygen (LOX) and rocket-grade kerosene (RP-1) propellants, on a SpaceX-designed rocket engine, the Merlin 1D. Multiple variants are planned with payloads of 53,000 kilograms to low Earth orbit (LEO), and 12,000 kilograms to geostationary transfer orbit (GTO).
