Engineers Complete 5th Green Run Test of Space Launch System Core Stage

Engineers have completed the fifth of eight Green Run tests on the core stage of NASA’s new Space Launch System (SLS) rocket, continuing progress toward a milestone hot fire test this fall. Operators concluded a test of the stage’s thrust vector control system on the historic B-2 Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Miss., on Sept. 13. The test provided critical verification of the control system and its related hydraulics as operators gimbaled the stage’s four RS-25 engines just as they must move during flight to steer the rocket and maintain a proper trajectory.
