New Glenn explosion linked to rocket engine valve

AI-summarised brief · reviewed before publication

Blue Origin identified a liquid‑oxygen valve in one of the seven BE‑4 engines as the source of the May 28 static‑fire explosion that destroyed its New Glenn rocket and heavily damaged Launch Complex 36 at Cape Canaveral. CEO Dave Limp announced that hardware recovery and inspections confirmed the anomaly originated at the main oxygen valve, and that component‑level and hot‑fire tests are guiding a quick‑fix retrofit slated for completion by month’s end. The company is rebuilding the pad and aims to return New Glenn to flight by year‑end. Because the BE‑4 also powers United Launch Alliance’s Vulcan Centaur, the defect could affect that program, though ULA has not detailed any schedule changes. The investigation also revealed that similar valve designs are used across batches, prompting reviews.
