埃隆·马斯克的SpaceX公司刚刚调整了其发展计划。

周日，这位首席执行官在SpaceX的一篇博文中表示，公司正将重心从火星转移到在月球上建造一座“自增长型城市”。

“只有每26个月行星连成一线时（行程需要6个月），我们才能前往火星，而我们每10天就能发射一次登月（行程需要2天）。”马斯克写道，“这意味着我们可以更快地迭代完成一座月球城市，而不是火星城市。”

这一声明与马斯克此前关于今年登陆火星的言论截然不同。

2020年，这位SpaceX首席执行官曾表示，他有信心公司将在2026年之前实现载人登陆火星。

“如果我们运气好，也许四年就能实现，”马斯克在2020年的一次颁奖典礼上说，“我们希望在两年内向火星发射一艘无人探测器。”

这家太空公司历来因项目复杂性和监管挑战而推迟雄心勃勃的项目。上周，该公司推迟了阿尔忒弥斯2号登月任务，这是50多年来的首次载人登月任务。

在周日的帖子中，马斯克补充说，SpaceX将继续建造火星城市，计划在五到七年内启动。

他写道，“但首要任务是确保人类文明的未来，而在月球可更快实现，”

上周，马斯克宣布SpaceX将收购xAI，这家人工智能公司开发了聊天机器人Grok。xAI于2025年3月收购了社交媒体平台X。

这位首席执行官写道，SpaceX收购xAI将打造“地球上（以及太空中）最具雄心、垂直整合程度最高的创新引擎，涵盖人工智能、火箭、太空互联网、直接面向移动设备的通信以及全球领先的实时信息和言论自由平台”。

在备忘录中，马斯克分享了在月球上建立“自给自足基地”和工厂的计划。他还提到“火星上建造一个完整的文明”。

Elon Musk’s SpaceX just overhauled its to-do list.

In an X post on Sunday, the CEO said that the company is shifting its focus from Mars to creating a “self-growing city” on the moon.

“It is only possible to travel to Mars when the planets align every 26 months (six month trip time), whereas we can launch to the Moon every 10 days (2 day trip time),” Musk wrote. “This means we can iterate much faster to complete a Moon city than a Mars city.”

The announcement is a big departure from Musk’s previous comments about reaching the red planet this year.

In 2020, the SpaceX CEO said he was confident that the company would land humans on Mars by 2026.

“If we get lucky, maybe four years,” Musk said at an awards show in 2020. “We want to send an uncrewed vehicle there in two years.”

The space company has historically delayed ambitious projects because of their complexity and regulatory challenges. Last week, the company delayed the Artemis 2 moon mission, the first human moon mission in more than 50 years.

In Sunday’s post, Musk added that SpaceX would continue building a Mars city, starting in five to seven years.

“But the overriding priority is securing the future of civilization and the Moon is faster,” he wrote.

Last week, Musk announced that SpaceX would acquire xAI, his AI company behind the chatbot Grok. XAI purchased the social media platform X in March 2025.

The CEO wrote that SpaceX’s xAI acquisition would create “the most ambitious, vertically-integrated innovation engine on (and off) Earth, with AI, rockets, space-based internet, direct-to-mobile device communications and the world’s foremost real-time information and free speech platform.”

In the memo, Musk shared plans to have “self-growing bases” and factories on the moon. He also mentioned having “an entire civilization on Mars.”
