前言： 今年8月，美国总统特朗普签署《促进商业航天工业竞争》行政令，以国家安全与经济振兴为由为商业航天松绑。 11月，中国国家航天局商业航天司成立，并发布《国家航天局推进商业航天高质量安全发展行动计划（2025-2027年）》。 一、从冷战缝隙到资本狂潮 1950年代，太空是美苏冷战的"战略赛场"——火箭带着卫星升空，背后是政府的巨额投入与军事目的，普通人连"商业航天"的概念都无从谈起。 1964年，国际通信卫星组织（Intelsat）的成立撕开了一道口子：他们把卫星变成"太空通信站"，为全球提供电话、电视信号服务，第一次让太空资源产生 了商业价值。1980年，法国阿丽亚娜航天公司成立，成为首个专门做商业发射的企业——从此，航天不再只属于政府，市场化的进程拉开帷幕。 1984年，面对欧洲商业发射能力竞争和本国商业航天公司的初现，里根政府推出《空间商业发射法案》，将火箭发射业务向私营企业开放。这是世界上第 一个鼓励商业航天发展的法规，也是美国商业航天真正意义上的起点。随后，GPS导航、电视广播卫星的需求爆发，轨道科学公司、劳拉空间系统公司这 些名字，开始出现在航天领域的名单里。但那时的私营企业，更像是"配角"— ...
