SpaceX Raptor Rocket Engine

The SpaceX Raptor is a full-flow staged combustion, methane-fueled rocket engine manufactured by SpaceX. The engine is powered by cryogenic liquid methane and liquid oxygen (LOX), rather than the RP-1 kerosene and LOX used in SpaceX's prior Merlin and Kestrel rocket engines. The earliest concepts for Raptor considered liquid hydrogen (LH
2) as fuel rather than methane.[11] The Raptor engine has more than two times the thrust of the Merlin 1D engine that powers the current Falcon 9 launch vehicle.
