NASA conducts a hot fire test Jan. 16, 2021

NASA conducts a hot fire test Jan. 16, 2021, of the core stage for the agency’s Space Launch System rocket on the B-2 Test Stand at Stennis Space Center near Bay St. Louis. The hot fire test of the stage’s four RS-25 engines generated a combined 1.6 million pounds of thrust, just as will occur during an actual launch. The hot fire is the final test of the Green Run test series, a comprehensive assessment of the SLS core stage prior to launching the Artemis I mission to the Moon.
