On May 28, 2026, Blue Origin’s New Glenn rocket experienced a catastrophic explosion at Launch Complex 36, Cape Canaveral Space Force Station, during a static fire test intended for a launch scheduled as early as June 4. Following an extensive investigation, Blue Origin CEO Dave Limp announced that the explosion was due to an issue with the main oxygen valve on one of the rocket’s BE-4 engines.
Limp confirmed that the anomaly was traced back to the main oxygen valve through hardware recovery and inspections conducted after the incident. He stated, “The anomaly originated at the main oxygen valve on one of the BE-4 engines, which was later confirmed by hardware recovery and inspections.” This revelation comes over two months after the explosion, which resulted in significant damage to Blue Origin’s sole orbital launch site.
Investigation and Testing
In response to the explosion, Blue Origin has conducted extensive component-level and engine hotfire tests to gain a deeper understanding of the failure mode and to inform necessary mitigations. The New Glenn rocket is powered by seven BE-4 engines, each capable of producing 640,000 pounds of thrust at liftoff, utilizing a fuel combination of liquid methane and liquid oxygen.
Path Forward
Based on the findings from the investigation, Limp indicated that the path forward is clear, stating, “We’re making small modifications to the valve that can be quickly retrofitted to existing engines.” The updated hardware is expected to be ready by the end of August 2026, while the team continues to analyze the remaining fault tree.
Impact on Future Missions
Despite the setback, Blue Origin is focused on returning the New Glenn to flight before the end of the year. The rocket is crucial for launching multiple Amazon Leo satellites and is also integral to NASA’s plans for its Blue Moon Mark 1 lunar landers. The first lunar lander, named Endurance, was initially scheduled for launch in late summer 2026 but has now been postponed to early 2027.
While Blue Origin addresses the issues with the New Glenn, the United Launch Alliance (ULA), which also utilizes the BE-4 engine for its Vulcan rocket, will implement necessary modifications to its engines as well. ULA has grounded its Vulcan rocket following a separate issue with a solid rocket booster during a recent mission.
