SpaceX的星舰火箭隔热罩可能成为实现快速重复使用的重大障碍。三位前NASA研究人员和专家指出，星舰第十三次试飞后，隔热瓦片出现明显裂痕和损伤，显示目前的热防护系统设计不足以支撑执行长马斯克对快速重复发射的雄心。尽管星舰成功降落在印度洋而非如先前试飞般爆炸，但高清影像揭示了瓦片的严重受损情况。（关键数字：24）

前NASA资深顾问查尔斯·米勒与前NASA研究员丹尼尔·拉斯基及前太空人查尔斯·卡马达共同分析认为，星舰使用的隔热瓦片与已退役的太空梭类似，可能采用陶瓷材料制成。这类瓦片在每次飞行后往往需要更换和翻修，无法达到SpaceX期望的每小时发射一次的目标。拉斯基表示，修复工作可能需要数周到数天，远非像飞机般清洁加油即可再次飞行。

专家警告，隔热罩问题可能影响SpaceX发射多达一百万颗人工智慧数据中心卫星的计划，并可能延误或增加为NASA执行载人登月任务的成本。航太新创公司Stoke Space正在开发新型隔热技术，但专家呼吁美国政府应立即重启对新型热防护技术的基础研究投资，以便SpaceX未来能够整合更先进的解决方案。

SpaceX's Starship heat shield may pose a major obstacle to Elon Musk's vision of rapid rocket reusability. Three former NASA researchers and experts raised concerns after observing significant tile damage following Starship's thirteenth test flight on July 24. While the spacecraft successfully landed intact in the Indian Ocean, high-definition footage revealed substantial cracking and damage to the thermal protection system tiles, leading the experts to conclude that the current design is inadequate for rapid turnaround between flights.

The analysts — former NASA senior adviser Charles Miller, former NASA heat shield researcher Daniel Rasky, and former astronaut Charles Camarda — believe Starship's tiles resemble those used on the retired Space Shuttle, likely made from a ceramic material requiring extensive inspection, repair, and replacement after each mission. Rasky, who co-invented the heat shield material used on SpaceX's Dragon capsule, estimated refurbishment could take days to weeks, far from the airline-like operations Musk envisions.

The heat shield limitations could impede SpaceX's plans to launch up to one million AI data center satellites and may delay or increase costs for NASA's lunar landing missions using Starship. While aerospace startup Stoke Space is developing alternative heat shield technology, the experts urge the U.S. government to immediately invest in fundamental research for advanced thermal protection systems that SpaceX could eventually incorporate into future Starship iterations.
