美国小型航天飞机之死
Guan Cha Zhe Wang· 2025-10-09 05:56
【文/观察者网专栏作者 白玉京】 中国福建舰电磁弹射五代机的轰鸣尚在耳畔,美国悄悄承认了另一个失败,判处本国新一代航天飞 机"死缓"。 近日,美国国家航空航天局(NASA)在官网挂出一则公告:决定不指望"追梦者"小型航天飞机为国际 空间站实施补给,只保留一次自由飞行演示的机会。 "追梦者"是美国全新一代的小型航天飞机,被NASA寄予厚望 NASA 小型航天飞机本应是中美同步开启的新赛道,如今在中国成飞"昊龙"的进击面前,"追梦者"却已未及入 轨便陷入停摆。历史总是以鲜明的对照书写:中国在电磁弹射的浪潮里打开新篇,而美国在航天飞机的 旧梦里步履蹒跚。"追梦者"的梦碎不仅是NASA的挫败,更让美国在小型航天飞机的探索上失去了宝贵 时间和主动权。 上个世纪的航天飞机是庞大的巨兽,过于复杂和昂贵 NASA 上一代航天飞机留给人类的,是辉煌与沉重并存的记忆。但这并不意味着航天飞机的路走到尽头,相 反,在可复用火箭逐渐成熟的今天,航天飞机的逻辑重新焕发出新的生命力。不同的是,这一次主角换 成了小型航天飞机。 我们必须要强调的是,不要小看"小型",并不是单纯的缩小尺寸,而是理念上的一次重构。在新一轮太 空竞争中,这种"小" ...
