The Moon is not lawless: an international treaty framework governs space activity, including lunar missions. The “legal wild west” label points instead to a gap between broad principles and the practical rules needed as more governments and companies plan to operate there.
The central distinction is between claiming lunar territory—which the Outer Space Treaty prohibits—and using resources found there, a question that remains contested in its application. No single rulebook has settled every issue of extraction, coordination, and access.

What laws govern the Moon?
The starting point is the 1967 Outer Space Treaty. It allows the exploration and use of outer space, including the Moon, under international law, while barring national appropriation of celestial bodies. A country cannot acquire lunar territory by declaring sovereignty, occupying it, or claiming it through another means.
The treaty also makes states responsible for their national space activities, including activities by nongovernmental entities. Private missions are therefore not outside the legal framework: states must authorize and continuously supervise them. The treaty calls for due regard for other states’ interests and consultation when an activity could cause potentially harmful interference.

Those are broad obligations, not a detailed operating manual for every lunar mission. The treaty does not itself specify all the procedures needed to coordinate nearby landings, share notice of activities, or manage competing plans for a resource-rich site. That difference—law exists, but practical details are still being worked out—is the reason the “wild west” metaphor persists.
Can anyone own land on the Moon?
No country can claim the Moon as sovereign territory under the Outer Space Treaty. That prohibition is not the same as a complete answer to whether an operator may own or control material it extracts. Territorial sovereignty and resource use are separate legal questions.

NASA’s account of the Artemis Accords says resource extraction and use can be consistent with the Outer Space Treaty when conducted in support of safe and sustainable space activity. It does not establish that every state agrees on the legal consequences of extracting, possessing, or allocating lunar resources. The distinction matters: a position advanced by Accords signatories is not, by itself, a universally accepted rule.

What are the Artemis Accords, and who do they bind?
Established in 2020 by NASA, the U.S. Department of State, and seven initial signatory nations, the Artemis Accords set out principles for participating governments. They reinforce the Outer Space Treaty and other agreements; they are not a new universal treaty. NASA’s page, updated September 25, 2026, describes commitments addressing transparency, peaceful purposes, emergency assistance, registration, open scientific data, heritage, resources, coordination, and debris mitigation.
The instruments differ in legal form and reach. The table summarizes the distinctions without treating their rules or participation as equivalent.
| Instrument | Legal form and reach | Territory and resources | Operational detail |
|---|---|---|---|
| Outer Space Treaty | International treaty obligations for its states parties; states are responsible for national activities, including nongovernmental ones. | Bars national appropriation of celestial bodies; permits exploration and use under international law. | Sets broad principles, including due regard and consultation over potentially harmful interference. |
| Moon Agreement | Treaty adopted by the UN General Assembly in 1979. NASA’s history overview says it was not ultimately ratified; it did not become a universal operating rule. | Not stated in the NASA history source summarized here. | Not stated in the NASA history source summarized here. |
| Artemis Accords | Principles for signatories, established in 2020; not a universal treaty. | NASA presents resource extraction and utilization as potentially consistent with the Outer Space Treaty when carried out safely and sustainably. | Sets out signatory commitments on matters including transparency, notification, coordination, and temporary safety zones. |
NASA reported 56 country signatories on September 30, 2025. That is a dated figure, not a current count. The number of countries that may have joined since then is not established here.
Are lunar safety zones claims to territory?
NASA describes Artemis Accords safety zones as temporary areas for notice and coordination around an operation, not permanent boundaries. Their size, scope, and duration should reflect the work being conducted, and they end when the operation ceases. Signatories also commit to respect free access and due regard for others.
These principles address a practical risk: a landing, excavation, or other activity could interfere with another mission if operators do not coordinate. But the Accords’ description is not proof that every state accepts every way a safety zone might be implemented as lawful. Treating a temporary coordination measure as a settled territorial right would overstate what the principles establish.

Why is the law still described as unsettled?
Broad treaty rules must be applied to concrete situations: who should notify whom about a mission, how operators can avoid harmful interference, and what fair access means when missions seek to use the same area or resources. The Outer Space Treaty supplies principles, but shared procedures for increasingly active lunar operations are still developing.
NASA’s September 30, 2025 report on Artemis Accords implementation discussions shows the work in progress. Participants discussed recommendations on non-interference, expected launch dates, general descriptions of activities, landing locations, orbital debris, interoperability, and data. These discussions are evidence of ongoing implementation, not a finalized global code.
The Moon Agreement is part of the history of attempts to address lunar governance, but it did not become the universal operating framework. The existence of that agreement, the Outer Space Treaty, and the Artemis Accords therefore does not mean every government follows one shared approach to resources or operational coordination.

The most consequential work is turning general duties into procedures that more states can recognize and use. That includes clearer notice and registration practices, ways to coordinate missions that could interfere with one another, and greater agreement on how resource use relates to the ban on territorial appropriation.
None of those questions erases the existing treaty framework. They determine how workable and widely accepted it will be as lunar activity expands. Until states build more common operational rules, the Moon will remain governed by law—but with important questions about how that law applies still being worked through.
