SpaceX is preparing to launch its mammoth Starship megarocket on its 14th test flight from South Texas, aiming for its first complete Earth orbit and a 10-hour endurance mission that will deploy 26 next-generation Starlink V3 internet satellites while testing critical orbital hardware and upgraded heat shield protections.
Standing an imposing 407 feet tall when fully stacked, the vehicle combines the Super Heavy booster and the Ship upper-stage spacecraft into the most powerful rocket ever built. After completing 13 suborbital test flights since April 2023, flight controllers are preparing for a massive shift in scope. The upcoming mission will push the massive spacecraft into a sustained trajectory rather than letting gravity pull it straight back down like a tossed ball, according to reporting from Mashable.
To stay aloft instead of crashing back to the planet, the vehicle must fly sideways at a staggering 17,500 mph. At that velocity, the spacecraft continuously falls toward the ground while Earth’s surface curves away at the exact same rate, keeping it in orbit.
Flight 14 Launch Window and Orbital Profile From Starbase
The 75-minute launch window opens at 7:15 a.m. local Texas time on Monday, September 28, from the private launch pad at Starbase in South Texas, pending regulatory approval. SpaceX plans to stream the historic attempt live on its website and on X, with broadcast coverage scheduled to begin roughly 30 minutes before liftoff.
Unlike previous missions that reached space and splashed down in the Indian Ocean within 65 minutes, Flight 14 will send the 171-foot-tall upper stage around the globe six times. Don Platt, director of the Spaceport Education Center at Florida Tech, noted in an interview with ABC13 that the flight serves as an extended check-out mission to gather vital data on how the vehicle performs during prolonged exposure in space.
“They’re going, finally, to a true orbital mission.”

Meanwhile, the Super Heavy booster is scheduled to splash down in the Gulf of Mexico approximately seven minutes after liftoff, following a boostback burn and landing burn.
Deploying Starlink V3 Satellites and Testing Heat Shield Upgrades
Flight 14 marks a major operational milestone by carrying a commercial payload designed to expand global connectivity. Starship will deploy 26 next-generation Starlink V3 internet satellites into low Earth orbit, which represent the initial members of a massive new megaconstellation. Each V3 satellite is rated for 1 terabyte per second of downlink transmission capacity—offering ten times the performance of older V2 mini satellites—and weighs nearly two tons, requiring Starship’s immense lift capability.
SpaceX CFO Bret Johnsen described the mission as the program’s first commercial, non-demonstration flight according to financial reporting by Yahoo, though internal accounting structures mean the Space segment recognizes zero inter-segment revenue when launching hardware for the company’s Connectivity division.
The extended flight will also subject the vehicle’s thermal protection system to unprecedented stress. Because the upper stage reenters the atmosphere from a true orbital trajectory rather than a suborbital arc, the higher entry velocity will test newly modified heat shield tiles.
Hardware Tweaks and the Road to Full Reusability
The upcoming launch incorporates several mechanical and software corrections implemented after anomalies observed during the previous flight. During the Flight 13 booster recovery, all 33 Raptor engines participated in the boostback burn for the first time, but terminal ice clogging in the three center engines caused an early shutdown and a hard splashdown in the Gulf. For the September 28 flight, SpaceX has installed upgraded fluid filtering hardware and revised software to enhance relight reliability across the propulsion system.
While future operational flights will require catching both the Super Heavy booster and the Ship upper stage using the launch tower’s mechanical chopstick arms—a feat the company has successfully executed three times with boosters but not yet with the upper stage—Flight 14 remains firmly in the development phase. Company leadership frequently characterizes full and rapid reusability as the holy grail of rocketry as detailed in coverage by Space, noting that mastering orbital insertion, propellant transfers, and life-support integration will ultimately dictate humanity’s timeline for establishing permanent settlements on the moon and Mars.
