The instant of the paradox right through the New Shepard shipment project NS-23, by which the booster’s engine failed.
Blue Foundation
Jeff Bezos’ house corporate Blue Foundation launched findings from an investigation into the failed flight of a shipment project ultimate 12 months, which it says was once because of a topic within the rocket’s engine nozzle.
The corporate’s New Shepard rocket, flying the NS-23 project wearing science and analysis payloads, suffered a failure in September 2022. No folks had been onboard, and Blue Foundation says its tablet’s emergency get away gadget functioned correctly, however the rocket’s reusable booster was once destroyed.
Bezos’ corporate had in the past stated little about its investigation during the last six months, which was once carried out with Federal Aviation Management oversight.
In a weblog put up on Friday, Blue Foundation stated it recognized “a thermo-structural failure of the engine nozzle” because the direct reason for the problem, and is now enhancing the engine, together with design adjustments to account for higher-than-expected temperatures right through the flight.
“Blue Foundation expects to go back to flight quickly, with a re-flight of the NS-23 payloads,” the corporate stated.

The New Shepard rocket launches from Blue Foundation’s personal facility in West Texas, wearing folks and payloads above 100 kilometers — or greater than 340,000 ft — for a pair mins of weightlessness. The tablet is flown autonomously, with out a human pilot, and floats down with the help of a suite of parachutes to land within the Texas barren region. The New Shepard rocket booster is reusable, returning to land on a concrete pad close to the release web site.
Blue Foundation stated its investigation discovered that NS-23 flight’s engine failure was once because of “operational temperatures that exceeded the anticipated and analyzed values of the nozzle subject matter.” The corporate recovered fragments of the BE-3PM engine’s nozzle, discovering “transparent proof of thermal harm and sizzling streaks as a result of larger running temperatures.”
The corporate famous that its design adjustments are supposed to make stronger the engine’s efficiency at prime temperature, in addition to toughen the engine’s nozzle.
