Rocket Report: Engines installed for Artemis III; Long March 6C breakup in LEO

NASA installed RS-25 engines on Artemis III’s Orion service module, finalizing its propulsion stack for the lunar mission. A Long March 6C upper stage broke apart in low-Earth orbit, generating debris that will decay in weeks. Blue Origin began constructing a Florida payload-processing facility while New Glenn remains grounded after a May launch-pad explosion, targeting a year-end return-to-flight. Isar Aerospace will launch a Spectrum vehicle from Andøya, Norway, in a week-long window starting Friday to deploy multiple CubeSats.
