Hot Fire Test of SLS Rocket Core Stage
Host Leigh D’Angelo (left) talks with NASA Space Launch System core stage engineer Alex Cagnola from Michoud Assembly Facility in New Orleans, during NASA TV live coverage from Stennis Space Center near Bay St. Louis, Mississippi, on Jan. 16, 2021. D’Angelo, also from Michoud Assembly Facility, hosted the NASA TV coverage prior to the hot fire test of the core stage for the agency’s Space Launch System rocket. 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.
