Lunar Laws: Moon Ownership

In 1967, at the height of the Cold War, the international community realized that space should not become a new battlefield for territorial conquest. This led to the creation of the Outer Space Treaty (OST), which remains the 'constitution' of space law today. Over 110 nations, including all major spacefaring powers, have signed it.

The most important rule for lunar ownership is found in Article II. It states that outer space, including the Moon, is not subject to 'national appropriation by claim of sovereignty.' This means no country can plant a flag and claim the Moon as its own territory. It is legally designated as the 'province of all mankind.'

While nations cannot own the Moon, the treaty does allow for exploration and use. However, this must be for peaceful purposes. Because the treaty focuses on 'nations,' it left a slight ambiguity regarding private individuals—a gap that would later spark colorful legal debates and entrepreneurial schemes.

By 1979, the United Nations tried to clarify the rules with a new document: the Moon Agreement. This treaty went a step further than the 1967 version by declaring the Moon and its resources the 'common heritage of mankind.' It proposed that if anyone ever mined the Moon, the profits should be shared equitably among all nations.

This idea was highly controversial. Major powers like the U.S., Russia, and China feared it would stifle innovation and prevent commercial investment. If you have to share your hard-earned profits with everyone, why bother spending billions to go there?

As a result, as of early 2026, only about 17 countries are parties to this agreement. None of them are major spacefaring nations. In fact, Saudi Arabia notably withdrew from the agreement in 2024. Because the big players haven't signed it, the Moon Agreement is largely considered a 'failed' treaty with little practical power.

You may have seen websites offering to sell you land on the Moon for $25 an acre. One famous example is the 'Lunar Embassy,' founded by Dennis Hope. He claimed that because the 1967 treaty only mentions 'nations,' individuals are free to claim the Moon. He even sent a declaration of ownership to the UN—and when they didn't reply, he took it as a 'yes.'

However, legal experts are almost unanimous: these deeds are legally meaningless. In international law, property rights only exist if there is a sovereign government to grant and enforce them. Since no nation owns the Moon, no nation has the power to give you a title to its land.

Most of these sellers now include fine print labeling their deeds as 'novelty gifts.' While it might be a fun present to hang on your wall, it won't hold up in any court of law if you ever tried to evict a NASA rover from 'your' backyard.

There is a massive legal difference between owning the *land* and owning the *stuff* you take out of the land. Think of it like deep-sea fishing: nobody owns the ocean, but once you catch a fish, it belongs to you. This is the logic many nations are now applying to lunar resources like water ice and Helium-3.

In 2015, the U.S. passed the Commercial Space Launch Competitiveness Act. This law explicitly tells American citizens and companies: 'If you extract a resource from space, it's yours.' It carefully avoids claiming the Moon itself, focusing only on the extracted materials.

Other countries like Luxembourg, Japan, and the UAE have passed similar laws. This 'finders keepers' approach is designed to encourage private companies to invest in the technology needed to utilize lunar resources without violating the ban on national territory.

To build a more modern framework, NASA and the U.S. State Department launched the Artemis Accords in 2020. As of early 2026, over 60 nations have signed on. These accords aren't a formal treaty, but they are a set of 'best practices' for lunar behavior.

The Accords explicitly support the extraction of resources and introduce the concept of 'Safety Zones.' These are areas where one nation is operating, and others agree to coordinate their activities to avoid 'harmful interference.'

Critics worry these safety zones could become 'ownership by the back door.' If you have a massive safety zone where no one else can go, aren't you effectively occupying that land? The Accords insist these are temporary and purely for safety, but the fine line between 'safe operation' and 'exclusive occupation' is the new frontier of space law.

If a private lunar rover from one company accidentally crashes into a research base belonging to another country, who is responsible? Space law has a very specific answer: the 'Launching State.'

Under the 1972 Liability Convention, the country that launched the object (or helped launch it) is 'internationally liable' for damage caused by that object on the surface of the Moon. This means governments are responsible for the actions of their private companies.

This creates a strong incentive for nations to strictly regulate their own commercial space sectors. If a private mission causes a disaster, the government could be on the hook for millions—or billions—in damages. It’s why you can't just build a rocket in your garage and blast off to the Moon without a stack of government permits and insurance policies.

As we move further into 2026, the 'Wild West' of space is getting more crowded. With NASA's Artemis missions and China's Lunar Research Station project both picking up speed, the race is on to establish permanent presences.

New challenges are emerging that the original 1967 treaty never imagined. How do we handle lunar 'heritage sites' like the Apollo 11 landing spot? How do we manage the limited amount of 'prime real estate,' like the sunlit peaks and water-rich craters at the lunar South Pole?

The next decade will likely see the development of more specific 'rules of the road.' We are moving away from the era of 'no one owns it' toward an era of 'who gets to use it first.' While the Moon remains technically unowned, the reality of its future will be shaped by those who build the infrastructure and set the standards for cooperation.
