赵泠的回答从公开情报看,不用解决什么问题,Starliner 现在就可以返回地球。之所以还要拖到七月底或八月,明面上的理由是要探究氮气泄漏、姿态推进器故障的原因。Starliner 返回地球并不需要所有姿态控制推进器参与。目前,Starliner 剩余的氦气可用约 70 小时,大幅超过在返回地球的约 7 小时飞行过程中为推进剂加压所需。看起来,发生故障的部件位于 Starliner 服务舱;按照设计,该舱会在 Starliner 返回地球的过程中分离并烧毁。波音以此声称他们需要更多时间在国际空间站上进行测试、分析数据。截止当地时间 2024 年 7 月 12 日,波音在白沙测试设施进行的地面实验尚未得到有用的结果。估计氦气泄漏和推?...
