SpaceX is set to launch Starship V3 from Starbase in Texas no earlier than 6:30 P.M. EDT tonight, beginning its 12th test of the megarocket and its first V3 demonstration. The flight aims to prove the vehicle can lift off, separate from the Super Heavy booster
At 6:30 P.M. EDT tonight—no earlier—Starbase in Texas will go quiet in the final minutes before Starship V3 lifts off, a vehicle built to look taller, push harder, and prove something new for SpaceX’s next big step.
The launch is the 12th test of Starship and the first demonstration of its V3 design. Fully stacked on top of SpaceX’s Super Heavy booster. the rocket stands about 408 feet (124 meters) tall and is designed to loft roughly 100 metric tons of cargo into orbit. Like previous Starship plans, the system is intended to return to Earth for reuse again and again.
Joseph Gonzalez. an associate professor of practice in aerospace engineering at the University of Illinois Urbana-Champaign and a former engineer for NASA’s Artemis program. describes V3 as more than another repeat flight. “For those who think this is simply another repeat test flight. the engineering changes under the rocket ‘hood’ are substantial. ” he says. He points to a rocket that is taller, exceeds 18 million pounds of total thrust, and introduces new Raptor 3 engines.
The booster, too, has been reshaped. Gonzalez says the vehicle architecture has moved from four steering grid fins to three larger. structurally reinforced fins positioned lower on the booster. a shift intended to improve control authority and thermal robustness. “All of these features and more changes to the rocket’s internal and external design will be tested on this flight. ” he adds.
SpaceX’s livestream of the liftoff is set to begin about 45 minutes before the launch window opens at 6:30 P.M. The broadcast will be available on SpaceX’s site and on X.
The flight’s mission profile is blunt: it’s a suborbital test intended to show Starship V3 can successfully launch, separate from its booster, and then splash down in the Indian Ocean. It is not meant to assess reusability, even if SpaceX hopes Starship will eventually be reused.
During the descent and test sequence, the spacecraft will release 20 dummy Starlink Internet satellites and two operational Starlink satellites. Those working satellites are designed to scan Starship’s heat shield and beam images back to Earth. providing ground teams with information about what the spacecraft’s thermal protection is experiencing during the return.
SpaceX also wants to relight one of the Starship’s Raptor engines while the vehicle is in space, a goal that adds another layer of difficulty to an already tightly choreographed attempt.
On the way back, the spacecraft will perform a series of maneuvers, including a flip, as it heads for its Indian Ocean splashdown. The booster, meanwhile, will drop into the Gulf of Mexico.
For SpaceX, the timing carries extra weight. Elon Musk’s company could go public in the next month. and a successful test of what Musk says will be SpaceX’s most powerful rocket is likely to draw fresh investor attention. The flight is also tied to NASA’s broader ambitions of using Starship to get astronauts back to the moon by 2028.
The tension inside tonight’s test is about proving readiness in stages. The mission isn’t trying to show full reuse. but it is designed to validate separation and key in-flight operations. while turning heat-shield inspection and satellite imagery into a tangible data stream from the hardest phase of reentry.
Gonzalez says that even when every objective isn’t met, the advances still matter. “Whether the mission achieves every objective or not, flights like this continue to push the aerospace industry forward and provide invaluable lessons for the next generation of engineers entering the field.”
