Which liquid oxygen/liquid hydrogen engine is currently under development to power the Blue Moon lunar lander?
Answer
The BE-7 engine
The Blue Moon lunar lander program is specifically relying on the BE-7 engine for its propulsion system necessary to achieve soft landings on the Moon. The BE-7 is characterized by its use of liquid oxygen and liquid hydrogen (LOX/LH2) as propellants, distinguishing it from the methane-fueled BE-4 or the kerosene-fueled BE-3 family. This engine is being developed precisely to meet the stringent performance requirements for delivering significant mass, up to 3,600 kilograms in its standard configuration, onto the lunar surface as part of the Artemis V mission objectives.
