What Happened

Malfunctioning Valve Blamed for Massive Pad Fire

Blue Origin has identified a malfunctioning valve as the cause of the massive explosion that destroyed its New Glenn rocket during a test at Cape Canaveral Space Force Station’s Launch Complex 36. According to CEO Dave Limp, the anomaly originated at the main oxygen valve on one of the BE-4 engines. The company is making small modifications to the valve, which will be ready by the end of the month. The explosion has delayed the company’s launch plans, but it is working to get the launch pad up and running to support New Glenn launches before the end of the year. This development was first reported by an unknown source.
