SpaceX Starship rocket launch postponed, Elon Musk says pressurant valve appears to be frozen
SpaceX推迟发射“星舰”,马斯克:压力阀似乎被冻结了
SpaceX called off its first launch attempt of its giant rocket on Monday. Elon Musk and his company had planned to launch the nearly 400-foot Starship rocket from the southern tip of Texas, near the Mexican border. SpaceX postponed the launch because of a problem with the first-stage booster. No people or satellites were aboard for this attempt. There won’t be another try until at least Wednesday.
SpaceX“星舰”原定于美国中部时间4月17日8时20分（北京时间4月17日21时20分）从美国得克萨斯州起飞，执行首次轨道级测试飞行任务。北京时间4月17日晚，SpaceX在推特上表示，“星舰”轨道级飞行测试取消，团队正在寻找下一个发射机会。
对于发射取消原因，SpaceX创始人马斯克在推特上表示，“一个压力阀似乎被冻结了，所以除非它马上开始工作，否则今天不能发射。”
