摘要

美国太空探索技术公司(SpaceX)的 "星际飞船"(Starship)火箭系统在第五次试飞中取得了一项重要的工程成就,负责将火箭送入太空的 "超重型 "助推器在德克萨斯州发射台的半空中被成功抓住。完成任务后,助推器与末级火箭分离,以减轻重量,让 "星际飞船 "继续它的旅程。通常情况下,火箭助推器要么在重返大气层时燃烧殆尽而被丢弃,要么坠入海洋,而在海洋中进行回收既具有挑战性,又成本高昂。相比之下,"超重型 "助推器的设计可以在陆地上回收,因此可重复使用性要实用得多。在最近的测试中,助推器重新点燃了部分发动机,减缓了下降速度,并导航返回发射场,在那里被发射塔的巨大机械臂抓住。这种回收火箭助推器的方法标志着在开发完全可重复使用的火箭方面取得了重要进展,其目的是降低成本,缩短未来任务的周转时间。
