- SpaceX intends to build a lunar “self‑growing city” within ten years, with Mars settlement to follow later.
- The shift reflects logistical, competitive and strategic factors, yet questions about feasibility persist.
What happened
SpaceX founder Elon Musk said on Sunday that the company has shifted its near‑term priority from establishing a settlement on Mars to developing a “self‑growing city” on the Moon, a goal he believes could be achieved in less than ten years. Musk described this new focus in a post on his social media platform X, suggesting that lunar development is a quicker way to “secure the future of civilisation” compared with the longer timelines associated with Mars missions.
Under the revised roadmap, SpaceX still intends to pursue Musk’s long‑held ambition of building a Mars city, potentially beginning within five to seven years, but lunar construction now takes precedence. The change in emphasis follows reports that SpaceX has told investors the Moon will be prioritised first, with a target for an uncrewed lunar landing around March 2027.
Musk’s explanation rests partly on orbital mechanics and logistics: while Mars alignment for missions occurs approximately every 26 months—with six‑month travel times—Moon missions can be launched much more frequently at roughly 10‑day intervals, with a two‑day transit. This, he argues, allows for more rapid iteration and development.
The pivot comes amid SpaceX’s wider strategic shifts, including its acquisition of the artificial intelligence company xAI—a deal that helps position the firm at the intersection of space, AI and satellite technology, and underscores Musk’s ambition to integrate space infrastructure with advanced computing.

Why it’s important
SpaceX’s new lunar priority highlights how technical and logistical realities can reshape even the most ambitious exploration plans. The Moon’s proximity to Earth and more frequent launch windows do, in theory, make it a more accessible starting point than Mars. Yet the concept of a “self‑growing city” remains largely undefined, and realising a self‑sustaining lunar settlement within a decade would require breakthroughs in autonomous construction, life support and resource utilisation that have not yet been demonstrated at scale.
There is also a broader context of international competition in lunar exploration, with agencies such as China’s CNSA advancing their own Moon plans. SpaceX’s shift could signal an attempt to secure a strategic foothold in this renewed space race.
Critics might argue that while grounding Mars ambitions in near‑term lunar goals could be prudent, frequent timeline revisions have marked Musk’s long‑term projects in the past, and the practical, financial and technological hurdles are substantial. The precise roadmap to a lunar settlement — much less a truly “self‑growing” one — remains to be elaborated in engineering detail.
