Boom 🔥 NASA conducted its second RS-25 engine hot fire test of the new year Feb. 8 on the Fred Haise Test Stand at NASAStennis Space Center near Bay St. Louis, Mississippi. This test was the third hot fire in the latest test series that began in mid-December. NASA is testing RS-25 engines to help power the Space Launch System (SLS) rocket on future deep-space missions.
