NASA’s Space Launch System (SLS) core stage pathfinder is positioned in the B-2 Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. The Pathfinder is the same shape, size and weight (without propellants loaded) as the actual SLS core stage flight hardware. Stennis work crews used it in August to train and practice handling and lifting techniques needed for the core stage flight hardware when it arrives at Stennis for testing in 2020. Watch our Story for more cool news on the Pathfinder later today! Credits: NASA #nasa #sls #spacelaunchsystem #rocket #artemis #wearegoing #tothemoon #space #exploration
