美国"太空"网站称，"天鹅座 XL"货运飞船这次任务遇阻，恰逢国际空间站面临补给问题之际。目前为国际空间站提供补给的包括美国的"天鹅座"货运飞船 和货运"龙"飞船、俄罗斯"进步"号货运飞船以及日本HTV-X货运飞船，它们按照固定节奏完成"制造-组装-发射"流程。然而今年3月的"天鹅座"飞船在运往发 射场的途中意外受损打乱了这个节奏，原定6月的补给任务被取消。之后，NASA不得不紧急调整补给时间表。其中4月21日发射的SpaceX货运"龙"飞船 （CRS-32）增加了货物装载量，以确保国际空间站上有足够的物资储备。 为了保证国际空间站的物资库存，这次"天鹅座XL"货运飞船凭借更大的运载能力，满载国际空间站所需的各种消耗品，如氮气、氧气、食物和厕所部件， 还有大量尿液处理器备件。美媒提到，如果"天鹅座XL"货运飞船未能与国际空间站顺利对接，国际空间站的补给将面临更严重的问题。按照当前计划，下 一次为国际空间站运送补给的是日本HTV-X货运飞船，它将于10月搭乘H3运载火箭升空。 "太空"网站还提到，"天鹅座XL"货运飞船这次意外事故还暴露出美国在近地轨道运载能力方面缺乏韧性。目前美国只有诺斯罗普·格鲁曼和Spac ...
