SpaceX's Starship — the largest and most powerful rocket ever built at 407 feet tall — is scheduled to attempt its first orbital flight on Monday, September 28. Flight 14 represents a categorical leap from the vehicle's 13 prior suborbital test flights, sending the Ship upper stage into Earth orbit for approximately 10 hours across six orbits before splashing down in the Pacific Ocean off Chile. The mission will deploy 26 next-generation Starlink Version 3 internet satellites, the first members of a planned megaconstellation that Elon Musk says will eventually number 100,000 spacecraft. SpaceX currently operates roughly 11,000 Starlink satellites in low Earth orbit. The new constellation represents both a revenue engine and a proof-of-concept for Starship's payload delivery capability. The flight architecture splits the two stages sharply. Super Heavy, the booster, will splash down in the Gulf of Mexico approximately seven minutes after liftoff — as it has on previous flights. Ship will circle the planet for nearly 10 hours before its Pacific splashdown. This is a dramatic departure from suborbital flights that lasted a maximum of 65 minutes and targeted the Indian Ocean. SpaceX has already caught the Super Heavy booster with the launch tower's "chopstick" arms three times, but has not yet attempted a Ship catch. That milestone remains for a future flight. Likewise, off-Earth propellant transfer — essential for any deep-space Starship mission — has not been demonstrated. Every mission beyond Earth orbit will require multiple rendezvous with tanker Ships to refuel the voyaging spacecraft. The industrial logic here is straightforward: full and rapid reusability of both stages is what SpaceX calls the "holy grail of rocketry." If achieved, it collapses the cost-per-kilogram to orbit by potentially one or two orders of magnitude. That's not incremental improvement — it's the difference between space access as a government-scale endeavor and space access as a commercial logistics problem. NASA has already bet on this trajectory, selecting Ship as the first crewed lunar lander for the Artemis program. Artemis IV aims to land astronauts on the moon in 2028. Between now and then, SpaceX must demonstrate propellant transfer, outfit Ship with life support, and achieve the reliability margins that crewed flight demands. Each of those is a multi-flight development program in itself. The launch window opens at 8:15 a.m. EDT (1215 GMT) with a 75-minute window from SpaceX's Starbase facility in South Texas. SpaceX coverage begins approximately 30 minutes before liftoff.
