Blue Origin blames engine for NS23 mishap

An overheated rocket engine was to blame for Blue Origin's failure last year, which resulted in grounded flights for the last six months.

During the September flight, as the New Shepard rocket started veering off course just a minute in, the escape system was triggered and the capsule was catapulted off and towed to safety.

The spaceflight company said that the cause of the NS 23 mishap was a thermo-structural failure of the engine nozzle. The crew's capsule escape system, which functioned as designed throughout the flight, was triggered by the resulting thrust misalignment. The rocket came crashing down while the payloads were brought to a safe landing at Launch Site One with no damage.

The wreckage was confined to the designated keep-out zone.

As part of the response to the crew capsule escape, the Propulsion Module commanded the shutdown of the BE 3 PM engine and followed an unpowered trajectory to impact within the defined flight safety analysis prediction, resulting in no danger to human life or property, according to Blue Origin.

The company said no one was hurt and the property on the ground was not damaged.

In just a matter of days, all critical flight hardware was recovered.

The Jeff Bezos-owned company found that a design change to the engine's boundary layer cooling system led to the problem after an investigation by the Federal Aviation Administration, National Transportation Safety Board and NASA members.

Blue Origin said that the problem is being corrected and that it is implementing additional design changes to improve structural performance.

Blue Origin expects to return to flight soon, with a re-flight of the NS-23 payload, according to Blue Origin.
