有网友提议在月球上建立永久基地，并从那里发射飞船到火星。对此，马斯克回应称：在月球上制造燃 料很困难，因为获取氢气和碳来合成甲烷（CH4）非常困难。在地球上则容易得多，因为甲烷储量丰 富。但也许当我们到达月球，城市开始运转时，情况就会有所改变。（格隆汇） ...

马斯克其后解释，对那些不知情的人来说，SpaceX已经将重心焦点转移到在月球上建造一座自生(self- growing)城市，因可能在不到10年内实现这一目标，而火星则需要20年以上。他指，前往火星只有在行 星每26个月对齐时才有可能，旅行时间为6个月，而SpaceX可每10天发射一次飞船前往月球，旅行时间 为2天，意味着可以更快地迭代，完成月球城市的建设，而非火星城市。马斯克称，话虽如此，SpaceX 仍将努力建造火星城市，并在大约5-7年内开始行动，但首要任务是确保人类文明的未来，而月球城市 建设的进展更快。他表示："SpaceX的使命依然始终如一不变：将我们所知的意识和生命扩展到星辰大 海。" 2月9日，马斯克在社交平台X发帖文表示，"是时候大规模重返月球"(Time to go back to the Moon at scale)。此外，有消息指SpaceX正在奥斯汀和西雅图招募工程师，以开发人工智能卫星和太空资料中 心。马斯克转发相关贴文回复表示是真的。 责任编辑：栎树 美股频道更多独家策划、专家专栏，免费查阅>> ...
