NASA Explores Methane Rocket Fuel Explosions for Safer Space Travel
NASA is studying the explosive properties of methane-based rocket fuels, now common in new engines. Companies like SpaceX and Blue Origin use these fuels, known as methalox, for their efficiency and reusability.
NASA is conducting tests to determine the explosive potential of methane rocket fuel. For over six decades, the space industry relied on kerosene, hydrazine, hydrogen and solid fuels. Methane-fueled engines gained traction about 15 years ago. SpaceX’s Starship uses 39 Raptor engines, while Blue Origin’s New Glenn and United Launch Alliance’s Vulcan rockets use BE-4 engines. Methalox engines offer advantages, including cleaner burning than kerosene, which SpaceX uses in its Falcon 9. Methane is also easier to handle than liquid hydrogen, as it does not require extremely cold storage.
