A small California-based satellite launch company, Launcher, is working to develop the most efficient rocket in the world for delivery of small satellites to orbit the Earth. The firm knew NASA’s Stennis Space Center in Mississippi would be the ideal testing location because of its secure facilities, expertise in testing full-scale rocket engines and components. Two years ago, Launcher got a U.S. Space Force Small Business Innovation Research (Phase II) award. The firm's first testing campaigns of its 3D printed E-2 liquid rocket engine at Stennis have been reaching important milestones. The latest was a successful thrust chamber assembly hot fire test of the 22,000-pound-thrust engine in August, following successful testing of its E-2 liquid oxygen turbopump in April and the first full-scale test fire of the E-2 engine injector and combustion chamber last year.
