Hydraulic system issue triggered early engine shutdown during SLS test-firing
NASA officials said Tuesday the weekend test-firing of the Space Launch System moon rocket’s core stage was cut short by an out-of-limits parameter in a hydraulic system for gimbaling, or vectoring, one of its engines. NASA Administrator Jim Bridenstine told Spaceflight Now engineers are “feeling pretty good” about the data gathered during the shortened test-firing, and managers may decide to ship the SLS core stage to the Kennedy Space Center for launch preparations without re-attempting the planned eight-minute hot fire.
