Boeing is getting ready to conduct the next phase of the Green Run test campaign for NASA’s first Space Launch System (SLS) Core Stage. The second and third test cases were recently completed in the B-2 Test Stand at the NASA’s Stennis Space Center in Mississippi.
Test case four begins this week and test case five after that will checkout the new stage’s Main Propulsion System hardware elements, performing fluid system leak checks and functional testing of the hydraulic thrust vector control (TVC) systems and four RS-25 engines.
