突发！马斯克升级版“星舰”火箭，发生爆炸！“测试中出现异常，具体原因尚未确定”！累计投入已超50亿美元

Core Insights - SpaceX's upgraded "Starship" rocket booster experienced an anomaly during testing, resulting in an explosion, with the specific cause yet to be determined [1] - The "Starship" is designed to be the largest and most powerful fully reusable space transportation system, with a height of 121 meters and a launch thrust of approximately 7600 tons, equivalent to the power of 15 Boeing 747s taking off simultaneously [3] - Elon Musk envisions "Starship" as a low-cost, high-frequency space transportation system, capable of launching "Starlink" satellites, transporting cargo and humans to the Moon and Mars, and enabling point-to-point high-speed travel on Earth [3] - SpaceX has invested over $5 billion in the "Starship" project, with significant costs associated with the construction of launch facilities and each test flight [3][4] - Supporters believe that once "Starship" is fully reusable, the cost per launch could drop to a few million dollars, comparable to transoceanic flights on large passenger aircraft [4] - The "Starship" project has become a landmark initiative in global commercial spaceflight, despite concerns about the risks associated with its "burning money for future" approach [4] Testing and Development - On October 13, SpaceX successfully completed the 11th test flight of the "Starship," achieving a controlled return to Earth after a successful launch and separation [5] - The previous ten test flights provided valuable data despite many failures, with the 11th flight seen as a significant milestone for the second-generation "Starship" [5][6] - The latest test utilized upgraded Raptor 2 engines and focused on validating high-temperature re-entry, thermal protection, engine restart, and payload release systems [5] - Following the recent test, SpaceX plans to shift its focus to the development of the next-generation "Starship 3" [6]
