Elon Musk’s New Priority: A Self-Growing City on the Moon in Under 10 Years

 Elon Musk has long been synonymous with ambitious visions for humanity's future in space, particularly through his company SpaceX. While his ultimate goal has centered on making humanity multi-planetary—starting with Mars—recent developments show a significant strategic pivot toward the Moon. In early 2026, Musk announced that SpaceX is now prioritizing the development of a self-growing, self-sustaining city on the Moon, potentially achievable in less than 10 years.

This shift doesn't abandon Mars but reframes it as a longer-term objective, with lunar efforts taking precedence to secure civilization's future more rapidly.Why the Moon First? Musk's RationaleMusk explained the change in priorities on X (formerly Twitter), highlighting practical advantages over Mars:

• Launch frequency and iteration speed — Missions to the Moon can launch roughly every 10 days, with travel times of about 2 days. In contrast, Mars opportunities align only every 26 months due to planetary positions, with journeys taking around 6 months. This allows far faster testing, learning, and scaling on the Moon.
• Timeline for self-sufficiency — A self-growing lunar city could emerge in under a decade, while a comparable Mars settlement might require 20+ years.
• Civilizational backup — Musk emphasizes the Moon as a faster path to establishing a resilient off-world presence. A catastrophe on Earth could sever supply lines to a distant Mars colony, but a lunar base would be more accessible and iterable.

He reaffirmed that SpaceX's core mission—to extend consciousness and life to the stars—remains unchanged. Mars city construction is still planned to begin in about 5–7 years, and lunar progress could even accelerate Mars efforts through shared technology and revenue.The Role of Starship and NASA's Artemis ProgramAt the heart of these plans is Starship, SpaceX's fully reusable super-heavy launch vehicle. Starship serves dual purposes:

1. As the Human Landing System (HLS) for NASA's Artemis program, which aims to return humans to the Moon sustainably.
2. As the foundation for large-scale lunar cargo and crew transport.

Key upcoming milestones include:

• Orbital propellant transfer demonstrations (targeted around mid-2026).
• An uncrewed lunar landing demonstration (potentially by March–June 2027).
• Crewed lunar landings (aiming for 2028 or later under Artemis III/IV).

These steps build toward frequent, high-volume deliveries to the lunar surface—essential for constructing a growing settlement. Musk has described a future where Starship enables "anyone" to travel to the Moon, making it accessible at scale.Beyond Landing: A Self-Growing Lunar CityMusk envisions more than outposts or temporary bases. The "self-growing city" concept involves using local lunar resources (regolith for construction, polar ice for water/oxygen/fuel) to expand autonomously. This could include:

• Industrial facilities, potentially for producing AI satellites or data centers in low-gravity, vacuum conditions.
• Mass drivers (electromagnetic catapults) to launch payloads cheaply into orbit.
• Integration with xAI initiatives for orbital AI compute, leveraging abundant solar energy.

Challenges remain—such as sourcing carbon and hydrogen for fuel and life support—but Musk asserts the Moon has sufficient resources to bootstrap a civilization.Implications for the FutureThis pivot aligns with geopolitical realities, including U.S. efforts to lead lunar exploration amid competition from other nations. It also ties into broader goals like protecting consciousness from Earth-bound risks while accelerating innovation through rapid lunar cycles.Musk's vision is bold: return to the Moon not just to visit, but to stay, build, and grow—paving the way for Mars and beyond. As he put it, the Moon offers the fastest path to a multi-world future.What do you think—will we see a thriving lunar city by the mid-2030s, or is this another ambitious timeline? The stars (and the Moon) are closer than ever.
