Overview
- Blue Origin said the May 28, 2026 static‑fire explosion at Cape Canaveral began at the main oxygen valve on one BE‑4 engine, a conclusion CEO Dave Limp announced on Aug. 5 and said was supported by recovered hardware.
- The company reported extensive component inspections and engine hotfire tests that have probed the failure mode and informed planned mitigations.
- Blue Origin plans small, retrofittable changes to the valve and is manufacturing updated hardware that it expects to have ready by the end of the month.
- The company is coordinating further upper‑stage testing with NASA in Mississippi as part of its effort to validate fixes and aim for a return to flight before the end of the year.
- The anomaly adds near‑term risk to New Glenn’s schedule and to Blue Origin’s Blue Moon support for NASA’s Artemis program after the rocket’s April launch loss and the May pad damage, and it could affect customers and regulators as fixes are certified.
