SpaceX plans to launch the next test of Starship on Thursday evening after a seven-month break spent rebuilding major parts of the rocket and its launch site.The company last flew Starship in October 2025. Since then, engineers have redesigned the engines, reworked the spacecraft's heat shield, and built a new launchpad at Starbase, SpaceX's private launch complex in South Texas.The upcoming mission, known as Flight 12, will debut what SpaceX calls the next generation of Starship and its Super Heavy booster. Together, the two stages stand about 400 feet tall and form the largest and most powerful rocket system ever built.

The test carries high stakes for both SpaceX and NASA. The U.S. space agency plans to use Starship to land astronauts on the moon as part of its Artemis program later this decade. At the same time, SpaceX founder Elon Musk wants the vehicle to eventually carry people and cargo to Mars. But before that can happen, the company must prove the rocket can launch reliably, survive the fiery plunge back through Earth's atmosphere, and eventually fly again without months of repairs between missions."The Starship production pipeline is full and will complete roughly 10 more ships and about half that number of boosters this year," Musk said in an X post on Monday. "If something goes wrong, it will not be a major setback, unless the launch stand is destroyed."
