Blue Origin found the part that failed

Blue Origin CEO Dave Limp attributed the May 28 New Glenn static-fire explosion to a main liquid-oxygen valve in one of the rocket’s seven BE-4 engines. Component tests and engine firings are shaping the fix. Naming the culprit is meaningful progress because corrective work can now be tested against a concrete failure mode; it is not, however, the same thing as proving the vehicle ready to return.
