The Daily Mail says that “Reaction Engine’s Sabre design uses a system of pipes, filled with helium. The air passes through these pipes and the helium helps remove any heat. Once in space, the engine is capable of switching into rocket mode. This means the craft can travel in orbit for around 36 hours and be used to launch satellites, for example.
