A on-stand camera offers a close-up view as NASA conducts a hot fire test March 18, 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, Mississippi. The hot fire test of the stage’s four RS-25 engines shown in the photo 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, which represents a comprehensive assessment of the core stage and its integrated systems prior to its launch on the Artemis I mission to the Moon.
