SpaceXs 403-foot Starship is set to lift off Sunday evening from the companys Starbase facility in South Texas, marking its most ambitious test yet after a string of setbacks.The launch, SpaceXs tenth test flight, comes after multiple failures in recent years including three disastrous explosions in 2025 alone.Between January and June, SpaceX suffered four Starship setbacks a dramatic explosion in its first test flight, a midair blast in the second, a fiery destruction in the third, and finally a ground-test explosion following those in-flight failures.Now engineers will attempt a series of high-risk maneuvers designed to prove Starships reusability, a critical step in owner Elon Musks long-term plan to reach the Moon and eventually conquer Mars.FORMER ASTRONAUT CELEBRATES SPACEXS IMPRESSIVE TECHNOLOGICAL TOUR DE FORCEThe goals for Sunday evening's test include deploying Starlink satellite simulators, attempting a landing burn with a backup engine, and guiding the Super Heavy booster into a controlled splashdown in the Gulf of America.SpaceX also hopes to make its first attempt at returning the Starship upper stage to the launch site.In the past, Musk has admitted that repeated setbacks are part of SpaceXs rapid test-and-fail approach.The Tesla founderfirst teased Sunday's test flight on Thursday, posting a photo of the gleaming spacecraft on X with the message: "Getting ready to launch Starship."SPACEX'S STARSHIP FLIGHT 9 ENDS IN FAILURE AFTER BOOSTER LOSS: 'SUCCESS COMES FROM WHAT WE LEARNStarship is the most powerful rocket ever built and is taller than the Saturn V that carried astronauts to the Moon in the sixties.The vessel consists of two stages: the 232-foot Super Heavy booster and the 171-foot Starship upper stage, where future crew and cargo will ride once the tests are successful.If successful, the new test mission would mark a breakthrough in Musks attempt to build a fully reusable rocket system capable of carrying humans deeper into space.SPACEX LAUNCH SCRUBBED HOURS AFTER HEGSETH SHARES MESSAGE TO RESCUE MISSION CREWThis would be a milestone for SpaceX, which has said it is essential for its Artemis moon lander contract with NASA and Musks ultimate goal of colonizing Mars.A live webcast of Sunday's mission will begin approximately 30 minutes before liftoff.Fox News Digital has reached out to SpaceX for comment.
