BE-4 Oxygen Valve Issue Grounds New Glenn Rocket

Blue Origin has identified the main oxygen valve on one of the seven BE-4 engines as the cause of the New Glenn rocket’s hot-fire test failure. The company plans to manufacture modified valve hardware and return the rocket to flight by the end of the year. Meanwhile, Rocket Lab has won a $397M Space Force contract to develop and launch a constellation of flat-packed satellites for threat tracking. Australia has also committed $518M to purchase AIM-260 JATM missiles, becoming the first export customer for the weapon. These developments were first reported by Ars Technica, Payload, and Breaking Defense.
