A SpaceX Starship prototype exploded during a static-fire test late Wednesday night at the company’s Starbase facility in Boca Chica, Texas. SpaceX CEO Elon Musk said the cause may have been a nitrogen pressure vessel failure in the upper stage. No injuries were reported, and safety zones protected nearby communities. This marks the fourth Starship lost in 2025 as SpaceX continues rapid testing under FAA oversight.
