After successfully testing the duct, the Marshall engineers moved on from the J-2X rocket engine to developing a smaller engine more compatible with the build box of available 3D printers.
Delivering 30 percent more thrust and five percent more performance than the J-2 Apollo-era engine, upon which it is based, the J-2X is the highest performing human-rated upper-stage engine to be developed in nearly 40 years.
The J-2X engine, designed and built by NASA and industry partner Pratt & Whitney Rocketdyne of Canoga Park, Calif., will power the upper stage of the 143-ton (130-metric-ton) Space Launch System (SLS) rocket.
The J-2X engine's nozzle is significantly similar to the nozzle Volvo Aero produces for the Ariane 5 ECA rocket's Vulcain 2 engine.
Dion Lee of Carriere, an engineering planner with the Lockheed Martin Test Operations Contract Group, was recognized for contributions to the J-2X and RS-25 engine programs and for providing timely resources management, performance analysis and scheduling mitigation support for day-to-day operations.
