【环球时报特约记者 晨阳】美国太空探索技术公司（SpaceX）于当地时间24日傍晚宣布取消"星舰"超重型火箭的第十次试飞，原因是地面系统（指发射台 及其周边支持起飞的基础设施）出现问题。美国"太空新闻"网站24日称，在今年"星舰"已经连续3次发射失败以及6月在发射台静态测试爆炸的背景下，"星 舰"未来命运如何备受关注。 然而"星舰"的进展并不顺利。自2023年4月首飞以来，在之前的9次无人测试中，只有4次被认为成功，今年开始的"星舰"V2版本所有3次试飞都遭遇了失败。 这也使得外界对于"星舰"的未来命运表示担忧。马斯克希望"星舰"最早能在明年获得载人航天认证。但"太空新闻"网站认为，这个计划面临太多挑战。 SpaceX首先需要证明"星舰"能够安全地发射和回收——到目前为止，它尚未完成第二级"星舰"飞船的安全返航着陆，更不用说登月之旅了。 美国有线电视新闻网援引英国咨询企业梅森研究公司太空事务分析师达拉斯·卡萨博斯基的观点称，"星舰"已经多次试飞，但"成功少于失败"，没法证明这 款火箭可靠，此次试飞任务因此压力极大。工程师出身的评论员威尔·洛基特认为，先前试飞均缺乏重型载荷测试，"星舰"的设计概念"本质上有缺陷 ...
