Check out this view from Stennis Space Center in southern Mississippi. Seen here from the A-1 test stand is the B stand complex (seen farthest away) and the A-2 test stand in the front. The B-2 stand will run the inaugural test of the Space Launch System core stage powered by 4 RS-25 engines. The A-2 stand currently holds the J-2X engine that is testing as a potential upper stage engine for future versions of SLS. SLS is being designed and developed by the Marshall Center in Huntsville, Alabama. Image: MSFC/NASA nasa.gov/SLS nasa.gov/Stennis nasa.gov/Marshall #nasa #slsinspires
