A first orbital try for the world’s biggest rocket
SpaceX’s Starship is scheduled to lift off from Starbase in South Texas on Monday, Sept. 28, during a 75-minute window that opens at 8:15 a.m. EDT, or 12:15 GMT . The company’s webcast is expected to begin about 30 minutes before liftoff, making the planned start of live coverage roughly 7:45 a.m. EDT if the countdown holds . Space.com is also carrying live coverage and mission updates for viewers who want a guided launch-day feed .
The headline is simple, but the flight plan is not: Flight 14 is designed to be Starship’s first trip to Earth orbit after 13 earlier integrated test flights that used suborbital trajectories . Previous Starship missions reached major milestones, including staging, reentry testing and soft splashdown attempts, but they did not enter a sustained orbit around Earth . If Monday’s attempt proceeds as planned, the Ship upper stage will climb into orbit, circle Earth six times, conduct a deorbit burn, reenter the atmosphere and splash down in the Pacific Ocean west of Chile nearly 10 hours after launch .
That long profile is why this flight is being watched so closely. Earlier Starship tests were short by comparison, with mission durations of about an hour or less; Flight 14 is designed as a full-day operations exercise for the vehicle, mission control and communications systems . SpaceX’s test objective is not merely to fly higher, but to show that Starship can enter orbit, manage a long coast phase, deploy payloads, leave orbit and survive the most demanding thermal and aerodynamic phases of reentry .
When and where to watch
The official launch window opens at 8:15 a.m. EDT and closes at 9:30 a.m. EDT on Sept. 28 . SpaceX’s own stream is expected through the company’s website and X account, with coverage beginning around 30 minutes before liftoff . For viewers who want to start earlier, NASASpaceflight has scheduled a dedicated Flight 14 webcast several hours before liftoff, with cameras positioned around the Starbase area .
SpaceX and Space.com both emphasize that the exact liftoff time can move within the window because of weather, propellant loading, pad operations or last-minute technical checks . If the rocket does not launch on Sept. 28, backup opportunities are expected on Sept. 29 and Sept. 30, with similar launch times based on local beach closure notices near Boca Chica . That makes this a “no earlier than” attempt rather than a guaranteed liftoff, even though the mission entered the final weekend with the vehicle stacked and rehearsed .
For in-person spectators, the most common public viewing areas remain on South Padre Island and around Port Isabel, across the water from Starbase . SpaceX does not operate an official public viewing site near the pad, and local traffic around launch attempts can be heavy . For most viewers, the livestream will be the safest and most reliable way to follow the full mission, especially because the planned flight extends far beyond the launch and booster splashdown.
The mission profile: orbit, satellites, reentry
Flight 14 begins like other Starship launches: Super Heavy, the first-stage booster, ignites its 33 Raptor engines and pushes the full stack through maximum aerodynamic pressure . Main engine cutoff is scheduled for about T+2 minutes and 20 seconds, followed by hot-staging separation and ignition of the Ship upper stage . Super Heavy then performs a boostback sequence and targets a soft water landing in the Gulf of Mexico about seven minutes after liftoff .
The biggest difference comes after Ship separation. Starship’s upper stage is expected to shut down its engines at about T+8 minutes, then perform an orbital insertion burn beginning around T+25 minutes and 17 seconds . If the vehicle passes health checks, that burn will place Ship on a trajectory roughly 171 miles, or 275 kilometers, above Earth . SpaceX has built in decision points: if the vehicle is not healthy enough to safely complete a later deorbit burn, mission controllers can shorten the flight rather than commit to the full six-orbit profile .
Payload deployment is scheduled to begin roughly 34 minutes after liftoff and continue for about 30 minutes . The cargo is not a dummy mass this time. Starship is slated to deploy 26 Starlink V3 satellites, the first operational batch of that larger next-generation spacecraft to be placed into orbit by Starship . SpaceX has said each V3 satellite adds about 1 terabit per second of capacity, for a total of roughly 26 terabits per second from this flight alone .
The final act is the hardest to fake in a ground campaign: controlled return from orbit. After several hours of coast, Starship is scheduled to perform a deorbit burn at about T+8 hours and 52 minutes, begin reentry around T+9 hours and 29 minutes, and attempt a flip and landing burn before ocean splashdown near T+9 hours and 50 minutes . The Pacific splashdown zone west of Chile is a change from earlier Starship upper-stage targets in the Indian Ocean .
Why SpaceX is not catching the rocket this time
Starship is designed to become fully and rapidly reusable, with both Super Heavy and Ship eventually returning to the launch site and being caught by mechanical arms on the launch tower . But that is not the plan for Flight 14. SpaceX is not expected to attempt a tower catch of either stage; Super Heavy is targeting the Gulf of Mexico, and Ship is targeting the Pacific Ocean .
That choice reflects the mission’s priorities. SpaceX has already demonstrated tower catches of Super Heavy on earlier flights, but it has not yet tried to catch Ship . On this mission, the main goals are orbital insertion, Starlink deployment, deorbit capability, reentry data and controlled ocean recovery profiles . In other words, Flight 14 is less about the spectacle of returning to the tower and more about proving the pieces needed for operational orbital service.
The prelaunch rehearsal added confidence that the stack was ready for the attempt. On Sept. 24, SpaceX completed a wet dress rehearsal, loading the vehicle and running through major countdown procedures without igniting engines . That test kept the 407-foot rocket on track for the Sept. 28 launch target and served as one of the last major integrated pad checks before flight .
Why the Starlink payload matters
The 26 Starlink V3 satellites make Flight 14 more than a pure engineering test . Earlier Starship missions carried Starlink-related payloads on suborbital paths, meaning those spacecraft were not meant to remain in service . This time, the satellites are intended to enter orbit, deploy antennas and solar arrays, establish communications links and begin raising their orbits for operational checkout .
That matters for SpaceX’s business as well as its engineering roadmap. Starlink is SpaceX’s global satellite internet network, and the larger V3 satellites are designed to add much more capacity than the smaller spacecraft typically carried by Falcon 9 . If Starship can regularly loft large batches of next-generation satellites, it could change the economics and pace of Starlink expansion .
It also gives the mission an unusually high-stakes payload for a first orbital attempt. SpaceX’s philosophy has long favored learning through flight, but putting operational satellites aboard a debut orbital Starship mission suggests confidence that the vehicle is ready to move beyond short-duration suborbital testing . The risk remains real: if Starship does not complete insertion, deployment, deorbit or reentry as planned, the company will still gain data, but the satellites may not become serviceable spacecraft.
What success would mean
A successful Flight 14 would not make Starship operational overnight. SpaceX still has to demonstrate rapid reusability of both stages, repeated high-cadence launches, reliable upper-stage recovery, and, for lunar and deep-space missions, orbital refueling . It must also develop crew-supporting systems before Starship can carry astronauts .
Still, reaching orbit would be a major threshold. NASA has selected a version of Starship as a lunar lander for the Artemis program, and SpaceX’s broader architecture for the moon, Mars and large-scale cargo delivery depends on Starship becoming a dependable orbital vehicle . The ability to deploy large payloads, return from orbit and eventually reuse both stages is the technical chain that links Monday’s test to those longer-term ambitions.
The most important thing for viewers to remember is that this remains a test flight. A scrub, delay, partial success or dramatic anomaly would not be surprising for a vehicle still in development. But if Starship reaches orbit, deploys its satellites and returns for a controlled splashdown, Flight 14 will mark the clearest step yet from experimental megarocket to orbital transportation system.
