Primer
The Artemis Accords
A primer on what they settle, and what they deliberately leave open
Non-binding commitments, signed 13 October 2020 and now joined by 72 nations, that affirm resource extraction is not national appropriation — while saying nothing about private entities or resources in place.

Eight founding signatories: United States, Australia, Canada, Italy, Japan, Luxembourg, UAE, United Kingdom.
Djibouti became the 72nd signatory on 16 September 2026. Open-ended; new states join by signing the same text with the United States.
A political commitment, not a treaty. Not submitted to the US Senate for advice and consent, and no ratification is required of any signatory.
The Accords describe themselves as an implementation of existing obligations, not new law.
No court, no arbitral body, no penalty. The only remedy is consultation and, ultimately, withdrawal.
The ten principles
The Accords are short. Ten commitments, none of which creates new law — each is framed as an implementation of obligations that already exist under the Outer Space Treaty and its companion agreements.
- 01
Peaceful purposes
Activities under the Accords are conducted exclusively for peaceful purposes, consistent with Article I of the Outer Space Treaty.
- 02
Transparency
Signatories commit to public description of their policies and plans, and to sharing scientific information.
- 03
Interoperability
Use of open international standards for systems, fuel storage, power, communications, and docking.
- 04
Emergency assistance
Reaffirms the 1968 Rescue Agreement — render aid to personnel in distress.
- 05
Registration of space objects
Determine which signatory registers an object under the 1975 Registration Convention, especially for joint missions.
- 06
Release of scientific data
Public release of scientific results on a good-faith basis; private operations are exempt from this commitment.
- 07
Preserving heritage
Protect historically significant sites and artifacts — Apollo landing sites among them.
- 08
Space resources
Extraction and use of space resources does not inherently constitute national appropriation under Article II of the Outer Space Treaty.
- 09
Deconfliction of activities
Notification and coordination through 'safety zones' — areas where interference is to be avoided, dissolving when the activity ends.
- 10
Orbital debris
Plan for safe disposal of spacecraft and mitigation of debris generation.
What it settles
Extraction is not appropriation
Section 10 states plainly that recovering and using space resources does not, by itself, amount to a national claim of sovereignty over a celestial body. For anyone financing a mining venture, this is the single most consequential sentence written since 1967: it removes the argument that touching a resource is itself a treaty violation.
Artemis Accords, Section 10 — Space Resources
Contracts have a place
The same section anticipates that contracts and other legal instruments relating to space resources will exist, and asks only that they be consistent with the Outer Space Treaty. That is an implicit acceptance that commercial arrangements over extracted material are legitimate.
Artemis Accords, Section 10
A workable coordination norm
Safety zones give operators a practical, notice-based mechanism for avoiding harmful interference under Article IX of the Outer Space Treaty — without waiting for a multilateral instrument that may never arrive.
Artemis Accords, Section 11 — Deconfliction of Space Activities
A coalition wide enough to matter
With seventy-one signatories, the Accords now represent a substantial share of spacefaring and aspiring-spacefaring states. Repeated, consistent state practice of this kind is one of the ways customary international law forms.

What it does not settle
This is the part that matters for capital formation, and the part most commentary skips.
They speak to states, not to people or companies
Every commitment in the text runs between governments. Nothing in the Accords creates, recognizes, or protects a right held by a private entity. A signatory nation can honor the Accords completely while granting its citizens no property interest of any kind.
Artemis Accords, preamble and Section 1 — Purpose and Scope
Silence on resources in place
Section 10 addresses extraction — resources recovered and moved. It says nothing about in-situ resources: the ore body still in the ground, the ice still in the crater floor, the surface and subsurface not yet touched. That silence is where the capital hesitates, because a claim you cannot hold before you dig is a claim you cannot finance.
Artemis Accords, Section 10; Outer Space Treaty, Article II
Safety zones are deconfliction, not tenure
A safety zone is temporary, activity-scoped, and explicitly framed as not creating a territorial claim. It is a traffic rule, not a deed. Treating it as a proxy for property rights overstates what the text will bear — and invites the appropriation objection the Accords were written to avoid.
Artemis Accords, Section 11
Nothing is binding, and nothing is enforceable
The Accords are political commitments. A signatory that departs from them breaches no legal obligation. For a venture underwriting a decade-long capital program, a norm that any administration can quietly abandon is not the same thing as title.
Artemis Accords, Section 13 — Implementation
They do not bind non-signatories
Russia and China have not signed. A bilateral network, however wide, does not settle a question of general international law against states outside it.

The 72 signatories
Eight nations signed on 13 October 2020. Mauritius became the seventieth on 17 July 2026. Listed in order of signing, with the region each state sits in — the spread across Africa, Asia, and Latin America is the strongest evidence that the Accords have moved beyond a narrow Western coalition.

DESIRING to implement the provisions of the Outer Space Treaty and other relevant international instruments and thereby establish a political understanding regarding mutually beneficial practices for the future exploration and use of outer space, with a focus on activities conducted in support of the Artemis Program;
COMMIT to the following principles:
Section 1
Purpose and Scope
The purpose of these Accords is to establish a common vision via a practical set of principles, guidelines, and best practices to enhance the governance of the civil exploration and use of outer space with the intention of advancing the Artemis Program. Adherence to a practical set of principles, guidelines, and best practices in carrying out activities in outer space is intended to increase the safety of operations, reduce uncertainty, and promote the sustainable and beneficial use of space for all humankind. The Accords represent a political commitment to the principles described herein, many of which provide for operational implementation of important obligations contained in the Outer Space Treaty and other instruments.
The principles set out in these Accords are intended to apply to civil space activities conducted by the civil space agencies of each Signatory. These activities may take place on the Moon, Mars, comets, and asteroids, including their surfaces and subsurfaces, as well as in orbit of the Moon or Mars, in the Lagrangian points for the Earth-Moon system, and in transit between these celestial bodies and locations. The Signatories intend to implement the principles set out in these Accords through their own activities by taking, as appropriate, measures such as mission planning and contractual mechanisms with entities acting on their behalf.
Section 2
Implementation
1.Cooperative activities regarding the exploration and use of outer space may be implemented through appropriate instruments, such as Memoranda of Understanding, Implementing Arrangements under existing Government-to-Government Agreements, Agency-to-Agency arrangements, or other instruments. These instruments should reference these Accords and include appropriate provisions for implementing the principles contained in these Accords.
(a)In the instruments described in this Section, the Signatories or their subordinate agencies should describe the nature, scope, and objectives of the civil cooperative activity;
(b)The Signatories' bilateral instruments referred to above are expected to contain other provisions necessary to conduct such cooperation, including those related to liability, intellectual property, and the transfer of goods and technical data;
(c)All cooperative activities should be carried out in accordance with the legal obligations applicable to each Signatory; and
(d)Each Signatory commits to taking appropriate steps to ensure that entities acting on its behalf comply with the principles of these Accords.
Section 3
Peaceful Purposes
The Signatories affirm that cooperative activities under these Accords should be exclusively for peaceful purposes and in accordance with relevant international law.
Section 4
Transparency
The Signatories are committed to transparency in the broad dissemination of information regarding their national space policies and space exploration plans in accordance with their national rules and regulations.
The Signatories plan to share scientific information resulting from their activities pursuant to these Accords with the public and the international scientific community on a good-faith basis, and consistent with Article XI of the Outer Space Treaty.
Section 5
Interoperability
The Signatories recognize that the development of interoperable and common exploration infrastructure and standards, including but not limited to fuel storage and delivery systems, landing structures, communications systems, and power systems, will enhance space-based exploration, scientific discovery, and commercial utilization. The Signatories commit to use reasonable efforts to utilize current interoperability standards for space-based infrastructure, to establish such standards when current standards do not exist or are inadequate, and to follow such standards.
Section 6
Emergency Assistance
The Signatories commit to taking all reasonable efforts to render necessary assistance to personnel in outer space who are in distress, and acknowledge their obligations under the Rescue and Return Agreement.
Section 7
Registration of Space Objects
For cooperative activities under these Accords, the Signatories commit to determine which of them should register any relevant space object in accordance with the Registration Convention. For activities involving a non-Party to the Registration Convention, the Signatories intend to cooperate to consult with that non-Party to determine the appropriate means of registration.
Section 8
Release of Scientific Data
1.The Signatories retain the right to communicate and release information to the public regarding their own activities. The Signatories intend to coordinate with each other in advance regarding the public release of information that relates to the other Signatories' activities under these Accords in order to provide appropriate protection for any proprietary and/or export-controlled information.
2.The Signatories are committed to the open sharing of scientific data. The Signatories plan to make the scientific results obtained from cooperative activities under these Accords available to the public and the international scientific community, as appropriate, in a timely manner.
3.The commitment to openly share scientific data is not intended to apply to private sector operations unless such operations are being conducted on behalf of a Signatory to the Accords.
Section 9
Preserving Outer Space Heritage
1.The Signatories intend to preserve outer space heritage, which they consider to comprise historically significant human or robotic landing sites, artifacts, spacecraft, and other evidence of activity on celestial bodies in accordance with mutually developed standards and practices.
2.The Signatories intend to use their experience under the Accords to contribute to multilateral efforts to further develop international practices and rules applicable to preserving outer space heritage.
Section 10
Space Resources
1.The Signatories note that the utilization of space resources can benefit humankind by providing critical support for safe and sustainable operations.
2.The Signatories emphasize that the extraction and utilization of space resources, including any recovery from the surface or subsurface of the Moon, Mars, comets, or asteroids, should be executed in a manner that complies with the Outer Space Treaty and in support of safe and sustainable space activities. The Signatories affirm that the extraction of space resources does not inherently constitute national appropriation under Article II of the Outer Space Treaty, and that contracts and other legal instruments relating to space resources should be consistent with that Treaty.
3.The Signatories commit to informing the Secretary-General of the United Nations as well as the public and the international scientific community of their space resource extraction activities in accordance with the Outer Space Treaty.
4.The Signatories intend to use their experience under the Accords to contribute to multilateral efforts to further develop international practices and rules applicable to the extraction and utilization of space resources, including through ongoing efforts at the COPUOS.
Section 11
Deconfliction of Space Activities
1.The Signatories acknowledge and reaffirm their commitment to the Outer Space Treaty, including those provisions relating to due regard and harmful interference.
2.The Signatories affirm that the exploration and use of outer space should be conducted with due consideration to the United Nations Guidelines for the Long-term Sustainability of Outer Space Activities adopted by the COPUOS in 2019, with appropriate changes to reflect the nature of operations beyond low-Earth orbit.
3.Consistent with Article IX of the Outer Space Treaty, a Signatory authorizing an activity under these Accords commits to respect the principle of due regard. A Signatory to these Accords with reason to believe that it may suffer, or has suffered, harmful interference, may request consultations with a Signatory or any other Party to the Outer Space Treaty authorizing the activity.
4.The Signatories commit to seek to refrain from any intentional actions that may create harmful interference with each other's use of outer space in their activities under these Accords.
5.The Signatories commit to provide each other with necessary information regarding the location and nature of space-based activities under these Accords if a Signatory has reason to believe that the other Signatories' activities may result in harmful interference with or pose a safety hazard to its space-based activities.
6.The Signatories intend to use their experience under the Accords to contribute to multilateral efforts to further develop international practices, criteria, and rules applicable to the definition and determination of safety zones and harmful interference.
7.In order to implement their obligations under the Outer Space Treaty, the Signatories intend to provide notification of their activities and commit to coordinating with any relevant actor to avoid harmful interference. The area wherein this notification and coordination will be implemented to avoid harmful interference is referred to as a 'safety zone'. A safety zone should be the area in which nominal operations of a relevant activity or an anomalous event could reasonably cause harmful interference. The Signatories intend to observe the following principles related to safety zones:
(a)The size and scope of the safety zone, as well as the notice and coordination, should reflect the nature of the operations being conducted and the environment that such operations are conducted in;
(b)The size and scope of the safety zone should be determined in a reasonable manner leveraging commonly accepted scientific and engineering principles;
(c)The nature and existence of safety zones is expected to change over time reflecting the status of the relevant operation. If the nature of an operation changes, the operating Signatory should alter the size and scope of the corresponding safety zone as appropriate. Safety zones will ultimately be temporary, ending when the relevant operation ceases; and
(d)The Signatories should promptly notify each other as well as the Secretary-General of the United Nations of the establishment, alteration, or end of any safety zone, consistent with Article XI of the Outer Space Treaty.
8.The Signatory maintaining a safety zone commits, upon request, to provide any Signatory with the basis for the area in accordance with the national rules and regulations applicable to each Signatory.
9.The Signatory establishing, maintaining, or ending a safety zone should do so in a manner that protects public and private personnel, equipment, and operations from harmful interference. The Signatories should, as appropriate, make relevant information regarding such safety zones, including the extent and general nature of operations taking place within them, available to the public as soon as practicable and feasible, while taking into account appropriate protections for proprietary and export-controlled information.
10.The Signatories commit to respect reasonable safety zones to avoid harmful interference with operations under these Accords, including by providing prior notification to and coordinating with each other before conducting operations in a safety zone established pursuant to these Accords.
11.The Signatories commit to use safety zones, which will be expected to change, evolve, or end based on the status of the specific activity, in a manner that encourages scientific discovery and technology demonstration, as well as the safe and efficient extraction and utilization of space resources in support of sustainable space exploration and other operations. The Signatories commit to respect the principle of free access to all areas of celestial bodies and all other provisions of the Outer Space Treaty in their use of safety zones. The Signatories further commit to adjust their usage of safety zones over time based on mutual experiences and consultations with each other and the international community.
Section 12
Orbital Debris
1.The Signatories commit to plan for the mitigation of orbital debris, including the safe, timely, and efficient passivation and disposal of spacecraft at the end of their missions, when appropriate, as part of their mission planning process. In the case of cooperative missions, such plans should explicitly include which Signatory has the primary responsibility for the end-of-mission planning and implementation.
2.The Signatories commit to limit, to the extent practicable, the generation of new, long-lived harmful debris released through normal operations, break-up in operational or post-mission phases, and accidents and conjunctions, by taking appropriate measures such as the selection of safe flight profiles and operational configurations as well as post-mission disposal of space structures.
Section 13
Final Provisions
1.Building on any consultative mechanisms in preexisting arrangements as appropriate, the Signatories commit to periodically consult to review the implementation of the principles in these Accords, and to exchange views on potential areas of future cooperation.
2.The Government of the United States of America will maintain the original text of these Accords and transmit to the Secretary-General of the United Nations a copy of these Accords, which is not eligible for registration under Article 102 of the Charter of the United Nations, with a view to its circulation to all the members of the Organization as an official document of the United Nations.
3.After October 13, 2020, any State seeking to become a Signatory to these Accords may submit its signature to the Government of the United States for addition to this text.

Criticism and open questions
A coalition of the willing, or law in the making?
Russia and China have criticized the Accords as a US-led attempt to set the rules outside the United Nations, and have advanced the International Lunar Research Station as a parallel track. Whether two competing frameworks converge into custom, or harden into rival regimes, is the central open question of the decade.
Can bilateral norms become customary law?
Customary international law forms from consistent state practice paired with a sense of legal obligation. Seventy-one states signing identical language is strong practice — but the Accords' own insistence that they are non-binding cuts against the second element.
Who adjudicates a safety-zone dispute?
The text calls for consultation. It does not say what happens when consultation fails, when two operators want the same crater rim, or when one of them answers to a non-signatory state.
Does COPUOS follow, or resist?
The UN Committee on the Peaceful Uses of Outer Space has a working group on space resources. Whether it ratifies the Accords' reading of Article II or contests it will shape how much weight the Accords carry outside their signatory list.
Why it matters here
The Accords moved the line: extraction is no longer the contested question. What remains contested — resources in place, and rights held by private entities rather than states — is exactly the gap the paper addresses.
No instrument in force forbids property rights in resources in place for private entities, apart from the Moon Agreement, which few nations have joined. The rules have simply not been written. Until they are, capital prices the ambiguity as risk and stays home.
