Blue Origin says it has identified the likely source of an explosion involving its New Glenn rocket during a static-fire test in May. The company traced the anomaly to a valve associated with one of the rocket’s first-stage BE-4 engines, according to reporting from SpaceNews and Space.com. In Space.com’s account, Blue Origin’s CEO discusses the investigation progress and points specifically to an oxygen valve. SpaceNews similarly reports that the company links the May explosion to a valve in the BE-4 engine, describing it as the component that triggered the problem during the test. Both outlets present the finding as part of an ongoing investigation rather than the end of it, but they agree on the general technical conclusion: a valve in the first-stage BE-4 engine is at the center of the failure analysis. The reports do not provide additional technical details beyond the valve linkage. Blue Origin’s updated assessment helps narrow the scope of corrective actions tied to future testing and potential launch activities.
