- Traditional rocket propellants include refined kerosene, hydrazine, hydrogen, and solid fuels, each with distinct advantages.
- Methane-fueled engines (methalox) are now being developed by major companies like SpaceX (Raptor) and Blue Origin (BE-4), offering benefits like less sooty residue and easier handling compared to kerosene or hydrogen.
- Methane is a cryogenic liquid but has warmer storage temperatures than liquid hydrogen, making it more practical.
- China achieved the first methane-fueled orbital launch in 2023, while US companies like Rocket Lab, Stoke Space, and Relativity Space are also advancing methalox technology.
- Safety concerns arise as agencies like NASA and the US Space Force study the hazards of methalox rocket explosions, especially with increasing launch frequency and proximity of launch pads.
- Methalox launch pads are operational or under construction at key US spaceports, including Kennedy Space Center, Cape Canaveral, Vandenberg, and Wallops, with SpaceX testing Starship in Texas under FAA jurisdiction.
