Colonizing the Moon: Legal and Physical Challenges of Managing Lunar Commons
The Moon is no longer a distant aspiration—NASA's Artemis program, China's Chang'e missions, and private companies are racing to establish permanent presence. Koskina et al. analyze the governance challenges: who owns lunar resources, how do we prevent a 'tragedy of the commons' in space?

The Moon, for the first time since the Apollo era, is a destination rather than a symbol. NASA's Artemis program plans to establish a sustained human presence at the lunar south pole. China's Chang'e program has already returned lunar samples and plans a crewed landing. India, Japan, the UAE, and private companies (SpaceX, Blue Origin, ispace) are pursuing lunar missions with increasing ambition.
This convergence of national and commercial interests on a single celestial body creates governance questions that humanity has never faced: Who owns the resources on the Moon? Can a nation or company claim exclusive rights to a lunar ice deposit? How do we prevent the "tragedy of the commons"—the degradation of a shared resource through uncoordinated exploitation?
Koskina et al. (2026, published in Frontiers in Political Science) analyze these questions through the framework of commons management, drawing on terrestrial precedents (ocean governance, Antarctica Treaty, atmospheric commons) while acknowledging that the lunar environment introduces challenges with no terrestrial analogue.
The Legal Landscape
Two competing legal frameworks govern lunar activity:
The Outer Space Treaty (1967): Ratified by all major space-faring nations, it declares that outer space "is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means." The Moon belongs to no one.
The Artemis Accords (2020): Led by the US and signed by over 60 nations as of early 2026 (but not China or Russia), the Accords establish norms for lunar activity including "safety zones" around operations and the right to extract and use space resources. Critics argue these norms implicitly create de facto property rights that the Outer Space Treaty prohibits.
The tension between these frameworks—one prohibiting appropriation, the other enabling resource extraction—is the central governance challenge. Koskina et al. argue that resolving this tension requires a new governance model that goes beyond terrestrial precedents.
The Physical Constraints
The Moon's physical environment imposes constraints that shape governance:
- Water ice: Concentrated in permanently shadowed craters at the poles, water ice is the most strategically valuable lunar resource (rocket fuel, life support, radiation shielding). These deposits are geographically limited—creating competition for the best sites.
- Regolith: The lunar surface material contains oxygen, silicon, aluminum, iron, and titanium—resources for construction and manufacturing. Regolith is abundant but processing requires energy-intensive extraction.
- Energy: Solar energy is available for ~14 Earth-days per lunar day (except at the poles where certain ridgeline locations receive near-continuous sunlight—"peaks of eternal light" that are prime real estate).
- Communications: Line-of-sight to Earth is intermittent for most lunar locations. Relay satellites are needed for far-side operations.
Claims and Evidence
<
| Claim | Evidence | Verdict |
|---|
| Multiple nations and companies plan permanent lunar presence | Artemis, Chang'e, commercial programs documented | ✅ Well-documented |
| Current legal frameworks are inadequate for lunar governance | Tension between OST and Artemis Accords analyzed | ✅ Supported |
| Lunar resources are geographically concentrated | Polar ice deposits, peaks of eternal light | ✅ Geological evidence |
| Terrestrial commons management models apply to the Moon | Partial applicability; lunar environment adds unique challenges | ⚠️ Partially applicable |
Open Questions
Resource rights enforcement: If a nation or company violates agreed-upon resource extraction norms, what enforcement mechanism exists? Unlike terrestrial commons (where coast guards and sanctions apply), space has no enforcement infrastructure.Environmental protection: Should parts of the Moon be designated as protected areas (like Antarctic wilderness reserves)? The Apollo landing sites have historical value; pristine permanently shadowed craters have scientific value.Equity and access: Should lunar resource access be limited to nations with spacefaring capability, or should benefits be shared globally (as the Moon Treaty—signed by almost no spacefaring nation—proposes)?Military use: The Outer Space Treaty prohibits military bases on the Moon. As dual-use technologies (in-situ resource utilization, autonomous construction) advance, the military/civilian boundary blurs.What This Means for Your Research
For space policy researchers, lunar governance is the most pressing near-term challenge in space law—decisions made in the next decade will establish precedents that govern human activity in space for generations.
For physicists and engineers working on lunar missions, understanding the governance framework shapes mission design: where you can operate, what resources you can use, and how you must coordinate with other actors.
