scroll 0 1 美国太空探索科技公司（SpaceX）2023年春天首次发射巨型“星舰”（Starship）火箭后，这家公司3年半以来一直宣称不久的将来就能让这座高耸的不锈钢机器进入轨道。9月28日，SpaceX终于在第14次发射实现这项目标。
综合报道，星舰当天首次进入轨道并部署新一代星链（Starlink）卫星，在第14次试飞跨过关键里程碑。此前13次星舰试飞都仅达次轨道高度；对任何要将酬载送入太空的新型火箭而言，成功入轨都是关键指标。

逾10年开发终入轨星舰跨过关键门槛
这项开发计划已历时近10年，迄今耗资超过150亿美元。 SpaceX打造星舰的初衷，是为了更频繁发射星链卫星，并执行美国国家航空暨太空总署（NASA）未来的登月任务。
SpaceX在社交媒体X宣布，“星舰执行轨道插入燃烧，首度进入地球轨道”。这艘太空船从德州星际基地（Starbase）升空，仅花费25分17秒便抵达距地面170英里的近圆形轨道。
这次成功对SpaceX及NASA的长期计划而言意义重大。星舰是将人类送往月球及火星的关键，也是SpaceX计划用以取代现有主力猎鹰九号（Falcon 9）火箭的核心。星舰拥有更大的酬载舱，最多可携带接近5枚猎鹰九号的货物量，未来可整合多次发射并大幅压低成本。
星舰这次的任务兼具高风险新一代火箭测试与实际营运性质，搭载价值数百万美元的星链卫星，成为其首度具备营收性质的商业任务。
