NASA conducted its second RS-25 engine hot fire test of the new year Feb. 8 on the Fred Haise Test Stand at Stennis Space Center near Bay St. Louis, Mississippi.
The 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 agency’s Space Launch System (SLS) rocket on future deep-space missions. Four RS-25 engines will generate a combined 2 million pounds of thrust to power SLS’s ascent.
