Hot Fire Test of SLS Rocket Core Stage

U.S. Representative Steve Scalise, left, NASA Administrator Jim Bridenstine and U.S. Senator Roger Wicker, right gather to watch as the core stage for the first flight of NASA's Space Launch System rocket undergoes a scheduled eight minute duration hot fire test in the B-2 Test Stand, January 16, 2021, at NASA's Stennis Space Center near Bay St. Louis, Mississippi. The four RS-25 engines fired for a little more than one minute and generated 1.6 million pounds of thrust. The hot fire is the final test of the Green Run test series, a comprehensive assessment of the Space Launch System’s core stage prior to launching the Artemis I mission to the Moon.
