Microcosm LOx/Kerosene rocket engine. First stages. Hardware. Pressure-fed, ablatively cooled engine using liquid oxygen and jet fuel as propellants. Flown 1999/2001.

Microcosm was developing a family of liquid-propellant rocket engines for its Scorpius series of ELVs and other users. The company has built a pressure-fed, ablatively cooled, 22,250-newton thrust engine using liquid oxygen and jet fuel as propellants. This engine was successfully tested on the company's SR-S and SRXM-1 sounding rockets launched in January 1999 and March 2001. The engine would also be used as the upper stage engine for the Sprite Mini-Lift orbital vehicle should that vehicle move into final development.

Propellant Formulation: Lox/Jet A.
