SpaceX Starship Explodes On Test Stand

SpaceX's Starship exploded on its test stand in South Texas ahead of an engine test, marking the fourth loss of a Starship this year. "In three previous test flights, the vehicle came apart or detonated during its flight," notes the Washington Post. No injuries were reported but the incident highlights ongoing technical challenges as SpaceX races to prove Starship's readiness for deep-space travel. From the report: In a post on the social media site X, SpaceX said that the explosion on the test stand, which could be seen for miles, happened at about 11 p.m. Central time. For safety reasons, the company had cleared personnel from around the site, and "all personnel are safe and accounted for," it said. The company is "actively working to safe the test site and the immediate surrounding area in conjunction with local officials," the post continued. "There are no hazards to residents in surrounding communities, and we ask that individuals do not attempt to approach the area while safing operations continue." Starship comprises two stages -- the Super Heavy booster, which has 33 engines, and the Starship spacecraft itself, which has six. Before Wednesday's explosion, the spacecraft was standing alone on the test stand, and not mounted on top of the booster, when it blew up. The engines are test-fired on the Starship before it's mounted on the booster. SpaceX had been hoping to launch within the coming weeks had the engine test been successful. [...] In a post on X, Musk said that preliminary data pointed to a pressure vessel that failed at the top of the rocket. You can watch a recording of the explosion on YouTube. SpaceX called the incident a "rapid unscheduled disassembly," which caught the attention of Slashdot reader hambone142. In a story submitted to the Firehose, they commented: "I worked for a major computer company whose power supplies caught on fire. We were instructed to cease saying that and instead say the power supply underwent a 'thermal event.' Gotta love it." Read more of this story at Slashdot.
