Vandenberg SDA Tranche 1 launch delayed after repeated scrubs

SpaceX’s Falcon 9 mission carrying 21 SDA Tranche 1 reconnaissance-related satellites has faced multiple scrubs, including an onboard automatic abort moments before liftoff. The vehicle and payload were reportedly healthy, with another attempt targeted around October 8; technical findings, weather, and range readiness remain the immediate variables. Planned LZ-4 recovery and possible sonic booms add operational interest.
