SpaceX is set to attempt the first orbital launch of its Starship rocket on Monday, September 28, in what the company calls the most significant test of the most powerful rocket ever built. The 14th Starship flight will also deploy the first operational batch of 26 Starlink V3 satellites, marking the start of a new generation of SpaceX's global internet constellation.
Liftoff is scheduled during a 75-minute window opening at 8:15 a.m. Eastern Time from Starbase, Texas. The roughly 10-hour mission will take the upper stage through about six orbits at an altitude of around 275 kilometres before a planned splashdown in the Pacific Ocean west of Chile. The Super Heavy booster is expected to splash down in the Gulf after its boostback and landing burns.

A leap from suborbital hops to real orbit

All 13 previous Starship flights since 2023 followed passively safe suborbital trajectories, nearly half of them ending in some form of unintended explosion. Flight 14 is the first to aim for sustained orbit, a shift SpaceX says opens the next phase of development toward a fully and rapidly reusable launch system. The vehicle pairs Booster 21 with Ship 41. SpaceX ran a full wet dress rehearsal on Thursday, walking through the entire launch sequence including propellant loading without igniting the engines. This time the company will not attempt to catch either stage with the launch tower's mechanical arms; both are targeted for ocean splashdowns while engineers gather data on the orbital profile.

Why this flight matters

A successful orbital mission would move Starship out of its test phase and into full operation, with effects reaching far beyond SpaceX. The 26 Starlink V3 satellites are designed to substantially increase the capacity of SpaceX's internet business, and Elon Musk has said the upgraded spacecraft will eventually host orbital data centres to power energy-intensive AI models. The flight is also closely tied to NASA's Artemis programme. Starship holds a multibillion-dollar contract to carry astronauts to the lunar surface, and the outcome of Flight 14 will signal whether the vehicle can keep the US return to the Moon on track amid a new space race with China.
The mission was originally scheduled for September 22 before slipping to Monday. SpaceX's live webcast is planned to begin about 30 minutes before liftoff, with coverage continuing through splashdown. As with all developmental testing, the company cautions the schedule remains dynamic.
