Blue Origin wants to resume spaceflight ‘soon’
The rocket flights of the Blue Origin company, owned by Jeff Bezos, have been interrupted since September 2022 and an in-flight accident.

The space company Blue Origin said on Friday it wanted to resume flights of its rockets “soon” but could only do so once the conclusions of an investigation into the causes of an accident last year were accepted by the regulator. air.
Blue Origin’s New Shepard rocket is notably used by Jeff Bezos’ company for space tourism flights from Texas, but at the time of the accident in September 2022, it was only carrying science experiments. The rocket is made up of a single stage and, at its top, the capsule carrying its cargo.
Anomalies
During the mission named NS-23, the main stage had suffered an anomaly, triggering the automatic ejection system of the capsule, which had fallen back to the ground slowed down by its parachutes. The main stage had “hit the ground”, Blue Origin said at the time, instead of landing in a controlled manner to be reused as usual.
An investigation has since been conducted, under the supervision of the American air regulator (FAA), to determine the reason for this accident. The investigation “remains open” for the moment and the flights of New Shepard rockets cannot resume until the investigation is officially closed, said the FAA requested by AFP. “The agency is currently evaluating the company’s incident report,” she added.
But Blue Origin has already shared the conclusions on Friday: the anomaly was caused by a “thermo-structural” problem at the level of the nozzle of an engine (the duct through which the gases in combustion are ejected) , which resulted in “misalignment” at the time of the push.
A few minutes in weightlessness
Specifically, this engine component was exposed to higher temperatures than expected, the investigation concluded. “Design changes” to several elements should prevent this problem in the future, the company explained.
Blue Origin said it wants to resume flights “soon” by restarting the NS-23 mission, with the same scientific cargo having been recovered intact. It “landed safely” following the anomaly, thanks to an ejection system that worked “as expected,” the company said.
Blue Origin has sent 32 people into space since July 2021, when its boss Jeff Bezos, founder of Amazon, took part in the first flight. Space tourists stay only a few minutes in weightlessness. The company Virgin Galactic is also positioned in this niche of short space tourism trips, but it has not flown anyone since July 2021.
