ULA's Vulcan Delivers Space Force Satellite to GEO Despite Booster Anomaly
ULA's Vulcan Centaur successfully placed a U.S. Space Force satellite into geosynchronous orbit after observers spotted an anomaly in one solid rocket motor; ULA will investigate the root cause and apply corrective actions before the next Vulcan flight, and a similar booster plume issue occurred on a 2024 flight.
