Team members at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, complete refurbishment work on the first core stage of the agency’s Space Launch System (SLS) rocket. The work followed a successful hot fire of the stage and its four RS-25 engines March 18. The hot fire marked the culmination of a yearlong Green Run series of tests of the stage and its integrated systems. Following refurbishment work, the core stage will be removed from the test stand and transported to Kennedy Space Center in Florida, aboard NASA’s Pegasus barge, shown delivering equipment to the B-2 Test Stand. At Kennedy, the core stage will be integrated with the rest of SLS rocket and prepared for the launch of the Artemis I mission to the Moon. Photo Credit: NASA
