NASA cleared a milestone in preparation for Green Run testing of its Space Launch System (SLS) core stage with an Aug. 23/24 lift and installation of the core stage pathfinder simulator onto the B-2 Test Stand at Stennis Space Center near Bay St. Louis, Miss. The lift and installation of the core stage pathfinder – a size and weight replica of the SLS core stage – is helping teams at Stennis prepare for the Green Run test series. For this test of the new core stage, Stennis will lift the flight core stage for Artemis 1, the first SLS mission into the stand. SLS and the new Orion spacecraft being built are the foundation for NASA’s Artemis Program, which will send the first woman and next man to walk on the Moon by 2024. 🌕 Credit: NASA #nasa #artemis #sls #rocket #orion #groundsystems #spacecraft #moon #exploration
