ExecutiveGov reports that NASA has conducted a hot fire test of an RS-25 certification engine on the Fred Haise Test Stand at Stennis Space Center in Bay St. Louis, Mississippi, “to validate its performance capabilities in supporting future deep space missions.” The engine was powered for eight and a half minutes by firing up to 113% power, which surpasses the requirement of 111% power to launch NASA’s Space Launch System for future Artemis missions. The hot fire “is part of a test series to certify production of the redesigned RS-25 engine for future deep space exploration missions, starting with Artemis V.”
