Blue Moon's Engine
The high specific impulse, deep throttling and restart capabilities of the BE-7 make the engine ideal for large lunar payload transport, while enabling Blue Moon's oxygen/hydrogen fuel cell power system.
BE-7 is an additively manufactured, high-performance, dual-expander cycle engine, generating 40 kN (10,000 lbf) thrust.
We are maturing the design, manufacturing hardware and about to begin hotfiring the engine. We’re also developing an integrated testbed under NASA’s Tipping Point award.
