Stennis Space Center Director Rick Gilbrech participates in a press conference following the Green Run hot fire test of the core stage for NASA’s Space Launch System (SLS) rocket on Saturday, January 16, 2021. NASA conducted a hot fire test of the core stage’s four RS-25 engines on the B-2 Test Stand at Stennis Space Center near Bay St. Louis, Mississippi. Scheduled for as long as eight minutes, the engines fired for a little more than one minute to generate 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.
