Starship could reach orbit for the first time today. SpaceX is targeting September 28 for Flight 14, with a launch window opening at 8:15 a.m. EDT, 12:15 UTC. The mission aims to deploy 26 Starlink V3 satellites and circle Earth six times before splashing down in the Pacific nearly 10 hours after launch. If successful, it would mark a major step beyond Starship’s previous suborbital tests. Live coverage is expected to begin about 30 minutes before liftoff. Launch timing may change.
