Blue Origin blames faulty valve for New Glenn explosion

Blue Origin has identified a faulty valve as the origin of the catastrophic explosion that destroyed its New Glenn rocket and damaged its launch pad during a pre-launch test on May 28, 2026. The company's chief executive, Dave Limp, stated this week that the failure originated at the main oxygen valve on one of the rocket's seven BE-4 engines, a finding confirmed through hardware recovery and inspections.

The anomaly occurred during a hot-fire test at Launch Complex 36A at Cape Canaveral Space Force Station in Florida. The explosion was powerful enough to register 2.5 on the Richter scale, caused significant damage to the launchpad infrastructure, and scattered debris. In the ten weeks since the incident, Blue Origin has focused on a dual-track effort: a technical investigation and rapid cleanup and reconstruction of the launch site.

Limp outlined a clear path forward, describing the required fix as relatively quick. The company is making small modifications to the valve design that can be retrofitted onto existing engines. Updated hardware is expected to be ready by the end of August 2026. However, Limp noted that engineers are still working through a remaining "fault tree...
