Asteroid mining is permitted in principle under the Outer Space Treaty, but there is no universal mining license or detailed global mining code. A country cannot claim an asteroid as its territory. Whether extracted material can be owned is a separate question: some national laws recognize ownership rights subject to conditions, while private operators remain subject to authorization and continuing supervision by the responsible state.
What the Outer Space Treaty allows—and prohibits
The 1967 Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, commonly called the Outer Space Treaty, is the basic framework of international space law. Its rules apply to celestial bodies, including asteroids.

Article I provides for the freedom of all states to explore and use outer space on an equal basis and in accordance with international law. It also says those activities are to be carried out for the benefit and in the interests of all countries. That framework permits exploration and use; it does not amount to a complete set of commercial mining rules.
Article II bars national appropriation of outer space and celestial bodies: “Outer space, including the moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means.” A state therefore cannot make an asteroid national territory by landing on it, occupying it or extracting material.

Can a company own material it extracts?
Territorial sovereignty and ownership of recovered material are different legal questions. The Outer Space Treaty bars a sovereignty claim over an asteroid, but it does not set out a detailed commercial title procedure for material after extraction. Several countries have adopted domestic laws that recognize rights in recovered space resources within their scope. Those national laws do not create a title rule binding on every state.
It is therefore too broad to say either that the treaty categorically makes asteroid mining illegal or that anyone may mine an asteroid and automatically own what they recover. The answer for a particular operator depends on the applicable national law, its conditions and the international obligations of the state overseeing the activity.

Who authorizes and supervises private mining?
Companies do not receive a direct international operating license under the Outer Space Treaty. Article VI makes states internationally responsible for their national space activities, including activities by private entities, and requires an appropriate state to authorize and continually supervise those private activities. In the treaty’s words, “The activities of non-governmental entities in outer space, including the moon and other celestial bodies, shall require authorization and continuing supervision by the appropriate State Party to the Treaty.”
Article VII addresses state international liability for damage caused by a space object in the circumstances it describes. Article IX requires states to act with due regard for the interests of other states and to consult where an activity may cause potentially harmful interference. These provisions matter to mission oversight and risk; they are not a substitute for a complete mining code.

In practice, an operator needs to identify the state or states responsible for or authorizing its activity and check the applicable approvals. A resource-mining authorization may not replace other required permissions. Launch, registration, liability and other mission-related requirements can also matter depending on the activity and jurisdiction.
How selected national laws treat space resources
The following examples show different national approaches, not interchangeable permits or a global rule. “Ownership” here concerns resources obtained, not ownership of the asteroid itself.

| Jurisdiction and legal source | Resource rule | Authorization and scope | Legal force and qualification |
|---|---|---|---|
| United States — Title 51, U.S. Code, chapter 513; added in 2015 | A U.S. citizen engaged in commercial recovery is entitled to a space resource obtained, including the rights to possess, own, transport, use and sell it, subject to applicable law and U.S. international obligations. The chapter defines space resources to include abiotic resources in situ, such as water and minerals, and defines an asteroid resource as a resource found on or within a single asteroid. | The law directs the President, through federal agencies, to facilitate commercial exploration and recovery by U.S. citizens and to promote operation free from harmful interference, subject to authorization and continuing federal supervision. | Domestic statutory entitlement with express qualifications; it does not grant sovereignty over an asteroid or bind all states. |
| Luxembourg — Law of 20 July 2017 on the exploration and use of space resources | States that space resources are capable of being owned. | Requires prior written authorization for a mission to explore or use space resources. Authorization is mission-specific, conditional and subject to continuing ministerial supervision. It is limited to specified entity forms under Luxembourg law or a European Company with a registered office in Luxembourg. The authorization does not dispense with other approvals. | Domestic statute. Luxembourg’s broader Space Activities Law of 15 December 2020 took effect on 1 January 2021 and provides a wider authorization and supervision framework. The Luxembourg Space Agency says the resource law clarifies the country’s position on extracted resources, not national appropriation of celestial bodies; its legal-framework page was updated 25 September 2026. |
| Japan — Space Resources Act of 2021 | A 2023 UN COPUOS Legal Subcommittee conference paper describes ownership of resources mined under a licensed business activity plan. | The same UN paper describes Japanese persons, including private entities, as able to explore, extract and use resources under the law. The cited summary does not establish detailed applicant qualifications, procedures or current implementing requirements. | National statute, described here through a secondary summary in a 2023 UN conference paper rather than the Japanese statutory text. |
| United Arab Emirates — national space-sector law and agency authorization process | The cited materials identify discovery of space resources as a regulated space activity; they do not establish an ownership entitlement identical to those described in U.S. or Luxembourg law. | The UAE Space Agency says permits are required for covered space activities and provides an online space-activity authorization process and requirements. | Domestic regulatory framework and agency guidance. The available description supports a permitting requirement, not a claim that the UAE creates the same recovered-resource title rule as the U.S. or Luxembourg. |
What the Artemis Accords and UN proposals add
The Artemis Accords are cooperative political commitments, not a universally binding asteroid-mining statute. The UAE Space Agency describes signatories’ position that resource utilization should comply with the Outer Space Treaty, benefit humankind and be critical to sustainable operations. Its signatory list is dated October 2024, so it should not be read as a current total.

They include peaceful use, sustainable technology, legal certainty, attention to developing countries and science, and state responsibility through authorization and continuing supervision. These are proposals for developing a framework, not rules adopted as binding law by all states.
What an operator must determine for a specific mission
The treaty establishes the international baseline, but it does not answer every licensing or title question for a particular company. A mission-specific legal assessment needs to identify:
- The responsible state: which state must authorize and supervise the operator under its international obligations.
- The applicable resource law: whether the operator and its planned activity fall within a national statute that recognizes rights in extracted material, and what conditions attach.
- All required approvals: whether the resource permit is mission-specific and what separate launch, registration or other authorizations are required.
- Oversight and risk obligations: what continuing supervision applies, and how the mission accounts for potential damage, due regard for other states and harmful interference.
This is a general overview, not a determination of any particular operator’s jurisdiction, license or liability exposure.
