Hardware across the vehicle continues to advance through test. 📍 Long Beach, CA The first stage downcomer completed its full acceptance test campaign. This flight-critical component, which routes liquid oxygen from the tank to the engines, is now cleared for integration. 📍 NASA Stennis, MS Stage 2 is back in the hangar after completing cryoproof and COPV proof testing. Post-test inspections are underway ahead of Aeon V installation. A2 is being prepped for hot fire, with LOX farm flushes and heat exchanger activations. On the R stand, acceptance testing of flight 2 Aeon R engines is underway.
