发射前30分钟叫停,SpaceX“星舰”第十次试飞再度延期
Jin Shi Shu Ju· 2025-08-25 09:46
埃隆·马斯克(Elon Musk)旗下的SpaceX在当地时间周日宣布,因发射场出现技术问题,取消了在德克 萨斯州进行的"星舰"第十次发射任务。这次发射原本被寄予厚望,有望实现此前多次因早期失败而未能 完成的一系列关键发展里程碑。 这些波折凸显出"星舰"最新版本的技术复杂性。新一代火箭配备了更强推力、潜在更耐用的隔热盾和更 坚固的襟翼,以确保大气层再入时的稳定与安全。这些改进也是马斯克长期强调的快速可重复使用的关 键所在。 按计划,整套系统原本应在当地日落时分升空,"星舰"上级火箭在数十英里高空与"超级重型"分离。不 同于此前尝试使用发射台巨型机械臂回收着陆,"超级重型"此次将目标锁定墨西哥湾,进行软着水实 验,以验证备用发动机的配置。 "星舰"则会短暂点火,进一步进入太空,尝试释放首批模拟"星链"卫星,并在亚轨道飞行途中再次点 火。此后,它将在印度洋上空再入大气层,这是测试新型隔热瓷砖与襟翼能否承受极端高温冲击的关键 环节。过去,多次再入过程中,火箭外层都曾被高温严重灼蚀。 马斯克原定在火箭升空前公布"星舰"的最新研发进展,但临时安排的直播最终显示该更新已被取消。 类似延期在以往通常只需数日即可解决。根据S ...
