Why will the exploration of space resources require international cooperation?

Why will the exploration of space resources require international cooperation?

By Philippe Reclus

summary

The exploration and prospective exploitation of space resources require international cooperation because no single state or actor can safely, equitably, or sustainably govern activities that span multiple orbital regimes, deep-space missions, and an expanding ecosystem of public, private, and international participants. A cooperative framework is viewed as essential to clarify rights and duties, manage shared risks, prevent harmful interference, and align divergent legal traditions with rapidly evolving technologies. Core tensions (such as whether resources extracted in space belong to the extractors, the interest in common heritage versus private property, and the security implications of dual-use technologies) drive calls for multilateral norms and formal or semi-formal governance mechanisms. Scholars and policymakers argue that a robust international regime is needed to govern extraction and use of space resources in ways that reduce duplication of effort, spread costs and risks, and facilitate scalable, long-duration programs beyond Earth and its immediate vicinity. At the same time, national interests, security concerns, and commercial incentives produce competing pressures: states seek capability, commercial players seek certainty and favorable regimes, and all must balance innovation with environmental protection, planetary protection, and liability concerns in a governance architecture that avoids unilateral action or regulatory fragmentation. Initiatives such as the Artemis Accords illustrate how nations and private actors can pursue cooperative norms without establishing a single universal ownership regime, while highlighting ongoing disagreements over sovereignty and appropriation. The international legal landscape shaping space resources combines existing treaties, evolving customary norms, and non-binding instruments. The Outer Space Treaty’s non-appropriation principle contrasts with domestic regimes recognizing extracted-resource rights, prompting debates about ownership, due diligence, and how best to prevent conflict as private activity grows. The Moon Treaty and related efforts illustrate competing interpretations of common heritage and resource governance, underscoring the need for consensus on licensing, safety zones, data sharing, and environmental safeguards, whether through hard international law, soft-law frameworks, or hybrid regimes that blend national implementations with cooperative norms. These dynamics fuel voluminous debates about how to manage access, ensure equity, and maintain safety in a crowded and increasingly contested near-Earth and cis-lunar environment. Looking forward, most analyses converge on a hybrid, multi-layered approach: codified norms and principles supplemented by national laws and targeted international institutions or authorities. Such a regime would aim to harmonize safety, environmental stewardship, liability, data rights, and benefit-sharing while preserving space as a global commons that supports both scientific advancement and responsible commercial activity. Proponents envision a framework that uses norm-building, soft-law instruments, and selective treaty evolution to provide predictable investment conditions and broad participation, without stifling innovation or over-centralizing authority. The balance of cooperation and competition will shape how effectively humanity can develop space resources while maintaining peace, security, and planetary protection in the final frontier.

Lead

The exploration and exploitation of space resources require international cooperation because no single state or actor can safely, equitably, or sustainably govern activities that span orbital regimes, resource availability, and a growing presence of private participants. Scholars argue that an international framework is needed to clarify rules governing extraction and use of space resources, and to address the shared interests and risks involved. The governance challenge is further sharpened by competing normative principles, such as the common heritage of outer space, which generates differing interpretations about whether benefits must be shared and to what extent, complicating unilateral action by individual states or companies. In addition, the management of high-risk activities (where harm can cross borders and affect the space environment) underscores the relevance of due diligence obligations, including the duty to prevent significant harm and to monitor and mitigate associated impacts. Practical models of cooperation, such as the International Space Station, illustrate how international collaboration can advance technical progress while distributing risk and responsibility among multiple actors. As space activities increasingly blend national and private interests, governance discussions emphasize accountability, sustainability, and equity to balance exploratory and commercial aims with the interests of the broader international community.

Why Cooperation Is Necessary

International cooperation stands as a central pillar in the exploration and potential commercial development of space resources, primarily because it can expand the resource base available for ambitious objectives and help avoid duplication of effort. By sharing capabilities (ranging from habitation, power, and life-support to launch and delivery systems) partner nations can reduce individual costs while enabling progress toward a core exploration architecture, such as a Deep Space Gateway or other long-duration missions. Moreover, overlapping timelines and divergent political interests across countries make sustained collaboration more likely to yield political stability and buy-in for activities beyond Earth orbit, a key challenge for long-term space programs in the United States and elsewhere. The prospect of cooperation, however, is tempered by concerns about national security and the potential transfer of sensitive technology to rival states. Cooperation with highly capable partners (particularly those perceived as security competitors) requires careful management of dual-use technologies and strategic risk, as space technologies often carry forward-looking benefits that could influence relative advantages. In this context, the balance between leveraging international capabilities and preserving a country’s competitive edge becomes a central consideration for policymakers. In pursuing space resource exploration and utilization, cooperation also intersects with commercial space development and space governance. The international dimension can help address regulatory gaps and provide a more predictable legal environment for private actors, especially given ambiguities in the application of existing treaties to private entities and commercial missions. At the same time, consistent rules of cooperation are needed to address access to and activities on shared assets such as the International Space Station and future outposts, ensuring that collaboration does not unduly constrain commercial innovation or raise barriers to entry. Economic analyses suggest that breaks in cooperation or delays in normalization of norms could hinder the scaling of space resource activities. Studies examining hurdle rates for commercial space resource development indicate high required returns under risk, underscoring the need for robust international and regulatory frameworks to de-risk investment and enable viable business cases in ISRU and related activities. Additionally, while exploration and resource utilization are inherently high-cost endeavors, the emergence of private space actors and evolving business models point toward the feasibility of coordinated, multinational approaches that combine public investment with private sector capabilities. Ultimately, cooperation is viewed not only as a path to resource development but as a mechanism to manage broader space governance challenges, including space traffic management, debris mitigation, planetary protection, and the protection of planetary environments from contamination. The five international space treaties, while foundational, were shaped primarily around state actors and leave regulatory gaps for private entities; coordinated international norms and regimes could reduce uncertainties and create a stable, competitive landscape for both government programs and commercial ventures.

Historical Context

The modern discourse on space resources has taken shape within a framework of international law anchored by the Outer Space Treaty and reinforced by evolving governance mechanisms both within and outside formal treaty structures. Early discussions and practice surrounding space exploration (often framed in terms of scientific activity rather than exploitation) helped establish a norm against national appropriation of celestial bodies, a stance encapsulated in OST Article II and clarified by scholars who distinguish exploration from exploitation and ownership rights. This historical distinction underpins ongoing debates about when, if ever, exploitation might amount to appropriation or require new legal formulations. Since the 1960s and 1970s, international diplomacy through UNCOPUOS and its subcommittees has sought to address the gaps between private sector activity and state-to-state obligations. The regulatory tools of UNCOPUOS (treaties, principles, and guidelines) have appeared to renew their relevance roughly every two decades, prompting calls for a new charter-like framework to define essential features and boundaries of space resource activities. In parallel, a bottom-up dynamic emerged as industry and civil society groups pressed for governance mechanisms outside the formal treaty environment, culminating in efforts such as The Hague’s Space Resource Working Group and the Building Blocks for the Development of an International Framework of Space Resource Activities released in November 2019, which sought to articulate rules for space resource activities prior to widespread commercial operations. These efforts reflect a broader shift from purely top-down rulemaking to a mixture of state practice and non-governmental initiatives intended to shape customary international law in this evolving field. The United States has played a central catalytic role in this historical trajectory. Domestic policy advances (beginning with the 2015 Act that initiated a space mining legal framework) were followed by a 2020 Executive Order under President Trump encouraging international support for space resource activities and signaling a push toward recognizing space resources within a growing body of practice. The 2020 EO, together with subsequent U.S. legislative proposals, indicates an ongoing effort to align national law with favorable interpretations of the Outer Space Treaty’s Article I and Article II, and to foster what some scholars describe as customary support for space resources among allied states such as Luxembourg, Japan, and the United Arab Emirates. In 2023, the 118th Congress considered the Space Resources Institute Act to promote U.S. leadership in space resources and the Commercial Space Act of 2023 to modernize oversight of commercial activities, illustrating how national legislation continues to influence international norms and potential treaty evolution. Mutual recognition of these developments is reflected in international initiatives like the Artemis Accords, which articulate governance principles outside the global institutional framework.

Nature of Space Resources and Operational Constraints

Space resources are objects located beyond Earth that may be accessed or utilized, including mineral resources, liquids and gases, radiation, orbital-frequency resources, and other materials associated with celestial bodies or their environments. The field is framed by a legal position that emphasizes space resources rather than ownership of celestial bodies, with a preference for personal property interests created through extraction activities rather than sovereign ownership. This interpretation is being shaped through a bottom-up process, where domestic laws influence evolving customary international law, a development reinforced by U.S. executive action and by other states pursuing analogous domestic regimes. The legal and governance landscape is characterized by ongoing debates about how space resources should be regulated, including how to reconcile extraction with prohibitions on sovereign ownership and the potential implications for international obligations under the Outer Space Treaty. In response, several fora (such as a Space Resource Working Group at The Hague, the Building Blocks for an International Framework of Space Resource Activities (released in 2019), and discussions within COPUOS’s Legal and Technical Subcommittee) have sought to create frameworks and rules that could govern future activities even before full commercial extraction begins. These efforts collectively aim to balance innovation with the avoidance of conflict, reflecting a shift from purely top-down regulation toward more proactive, multilateral governance mechanisms. A key operational consideration is the distinction between “mining” and space-resource activity. Some analyses argue that space resource extraction resembles harvesting rather than real-property mining, because it involves acquiring resources rather than attaching rights to the land itself, a distinction that has implications for property rights and governance. The practical effect is to frame space resource activities as personal-property-like rights to extracted materials, which can influence licensing, authorization, and supervision regimes. Cataloging scarce resources and understanding their limits are highlighted as critical tasks for governance. Proposals advocate creating a living list of resources and regions where scarcity conditions apply (such as the peaks of eternal light at the lunar poles or the radio-quiet zone on the far side of the Moon) and ensuring that states and operators publicly commit to recognizing and respecting this list. This approach underpins monitoring, data dissemination, and adaptive governance as new discoveries and extraction data become available, enabling more transparent and evidence-based regulation. The broader strategic environment recognizes significant operational constraints. Competitive dynamics around resource-rich regions (especially the Moon’s south polar area, where water ice is of potential scientific and logistical value) raise concerns about crowding, site selection, and potential interference among diverse actors. Without proactive management, both scientific and commercial missions could suffer. At the same time, commercial activities are seen as potentially contributing to a stable, cooperative space economy if anchored in predictable law and international cooperation, even as questions about jurisdiction, space traffic management, debris, and security persist. Practical examples of emerging space-resource activity highlight the ongoing transition from theoretical frameworks to real-world operations. Companies like ispace have engaged in agreements to collect and transfer lunar regolith, signaling a move toward commercialization and property-rights-based arrangements in practice, despite setbacks in mission execution. This underscores the need for a predictable and secure legal environment to attract investment while safeguarding sustainable, cooperative exploration.

International Legal and Policy Framework

International law regards a variety of actors as subjects with rights and obligations on the international plane, including states, international organizations, certain non-state actors, indigenous peoples, and increasingly supranational entities; this evolving landscape underpins the need for cooperative governance of space activities. In the context of space resource activities, states and international organizations may establish area-based safety measures or safety zones around identified resource activity sites to ensure safety and prevent harmful interference, while maintaining freedom of access under international law for other actors. Such arrangements commonly require international consultations in cases of overlapping safety zones or potential conflicts with established freedoms of access. The Artemis Accords and related policy instruments emphasize that national laws are primary in governing space activities and resource claims, rather than creating new international property rights; they seek to reaffirm and coordinate with existing national frameworks rather than unilaterally imposing international rules. This approach highlights the coexistence and interaction of national regimes with international norms, illustrating how a network of current and forthcoming laws underpins the governance of space resources. A key challenge under the Outer Space Treaty (OST) is the prohibition on national appropriation of outer space, the Moon, and celestial bodies, alongside encouragement of peaceful exploration and use; this tension has fueled debates about space mining and ownership at the national level, with several states enacting domestic laws that recognize or incentivize resource extraction within the bounds of international obligations. While some domestic regimes recognize property claims over extracted resources, they stop short of allowing sovereignty over celestial bodies themselves, signaling a pragmatic approach to allow exploration and utilization without contravening the OST. Underpinning both international and domestic actions is the duty of due diligence in space governance. International law emphasizes that states must undertake appropriate and precautionary measures to avoid significant harm to other states, conduct impact assessments, and engage in notification and consultation with potentially affected parties; these procedural and substantive elements are essential for managing space activities with high risk and increasing privatization. The due diligence framework underscores the need for international cooperation, information sharing, and alignment with applicable rules and standards as space activities expand and diversify. In practice, the evolving framework for space resource governance draws on existing mechanisms for resource rights and safety management, including the Moon Agreement concepts, ITU systems for orbital resources, and deep seabed regimes under the UN Convention on the Law of the Sea, while carefully assessing compatibility with space law to avoid conflicts between priority rights and international obligations. The dynamic interplay between national initiatives and international law thus necessitates robust cooperation, transparent decision-making, and ongoing dialogue among states, international organizations, and non-state actors to navigate the governance of space resources effectively.

Legal Status, Disputes, and Illustrative Ambiguities

Proponents and commentators have debated how international law governs the legal status of space activities, including whether and how private actors may acquire rights in space resources while respecting the Outer Space Treaty (OST) and related instruments. The Advisory Opinion context and subsequent analyses emphasize that due diligence and risk assessment are central to states’ obligations, but the precise content of those obligations varies with circumstances and factual contexts. In practice, the duty of due diligence blends substantive measures (such as precautionary actions to avoid significant harm) and procedural elements, including notification and consultation with potentially affected states, all assessed against available scientific and technical information and applicable standards. A core tension in the legal regime concerns non-appropriation and the status of private actors. Under the OST, sovereignty over outer space is prohibited from appropriation, and disputes have centered on whether and how resources found or extracted in space can be owned or claimed by states or private entities. Some legal commentaries note that while private actors operate under the authority of their national governments, jurisdiction over activities remains with the authorizing state, which complicates the prospect of private ownership of celestial bodies or extracted resources absent state sanction. This framework has led to licensing schemes, such as those observed in domestic space laws, which permit property claims only over resources that have been extracted rather than over celestial bodies themselves, thereby attempting to reconcile private interests with non-appropriation commitments. The Moon Treaty and related instruments further illuminate ambiguities in resource governance. The Moon Treaty explicitly treats the Moon as a common heritage of humankind and calls for a regime governing exploitation, contrasting with the more limited or non-ownership emphasis found in the OST. Some legal scholars argue that, despite the non-appropriation principle, certain regimes permit license-based resource extraction under state authorization, pointing to national laws that recognize property rights in extracted resources while avoiding ownership claims over celestial bodies or in situ resources, thereby navigating the constraints of the treaties. Others highlight potential loopholes, such as differentiating between in-situ resources and those removed from the surface, which some analyses suggest could influence claims under the Moon Agreement’s Article 11 concerning proprietary rights to resources “in place” versus those removed from the surface. Disputes and interpretive ambiguities also arise around customary versus conventional law and the role of guiding principles in treaty interpretation. International practice has long treated due diligence as a corollary duty of sovereignty, requiring states to protect rights within their territory while avoiding actions contrary to the rights of other states; this has been discussed in cases and opinions across ICJ and related authorities. The relationship between customary norms and treaty provisions remains a live issue, with references to evolving jurisprudence and ILC work underscoring that the concrete meaning of due diligence depends on the particular facts and circumstances of each case. Some perspectives situate these debates within broader questions of how humanity as a whole, or “humankind” as a subject of international law, might participate in or influence governance, an argument tied to debates about common heritage and the evolving catalog of international legal subjects . Illustrative ambiguities also stem from the practical deployment of space activities by non-state actors. The jurisdiction and accountability structure (whereby states authorize private activities and thereby bear responsibility) creates a gap between the letter of non-appropriation and the reality of private exploitation and licensing arrangements. In the absence of a universally agreed framework for ownership of space resources, several states have begun to articulate domestic regimes that recognize extracted-resource rights while maintaining compliance with international prohibitions on ownership of celestial bodies. This patchwork of approaches underscores the ongoing need for international cooperation and clear norms to prevent disputes over resource exploitation and to align national regimes with evolving interpretations of due diligence, non-appropriation, and common heritage principles.

Governance Models and Coordination Mechanisms

Given the diverse actors and interests in space resources, several governance models have been proposed to coordinate exploration, exploitation, and sharing in a peaceful and sustainable manner. A common theme across these models is the move toward adaptive, consent-based frameworks that balance national interests with international cooperation and shared norms. For example, the idea of a Lunar Governance Charter has been advanced as a reference framework focused on guiding principles and shared agreements rather than prescriptive resource-management protocols, with emphasis on peace, cooperation, accessibility, and opportunities for adaptive learning and evolution. This approach aims to scaffold broader governance by outlining aspirations and responsibilities while avoiding over-specification of institutional structures. International process and institutional pathways underpin these models. The United Nations framework, including the Working Group on Legal Aspects of Space Resource Activities, envisions a final report and a set of initial recommended principles produced through consensus, with open participation by States members and encouragement of developing and emerging spacefaring countries. The Working Group’s five-year plan calls for early administrative tasks, stocktaking, and submissions from states to establish a baseline for ongoing deliberation, followed by an exchange of views on initial principles that ensure activities are conducted in accordance with international law and in a safe, sustainable, rational, and peaceful manner. The working group is to be guided by established procedures, with leadership by a Chair and Vice-Chair and support from the Secretariat, and it remains open to all States members, reinforcing broad international legitimacy and inclusive participation. Practically, governance models emphasize a combination of international norms, national implementations, and non-governmental engagement. The Artemis Accords and related policy work illustrate how national laws can function as a bridge to international norms, reaffirming existing national legislation and encouraging the development of new laws while avoiding the creation of a single universal ownership regime for space resources; rather, these instruments signal that customary international law and treaty rules can coexist and gradually reinforce shared standards, with national frameworks providing the operational backbone for compliance. The development of soft-law instruments and national laws is seen as a way to specify broad principles in a practical, context-sensitive manner while preserving flexibility for diverse legal systems. Coordination mechanisms proposed include clear procedures for authorization and licensing, ongoing supervision of space activities, and the establishment of safety standards and technical norms, all of which are seen as essential to a unified, cross-jurisdictional framework that can accommodate multiple national and private operators. Some national examples explicitly require licensing and ongoing oversight, illustrating how governance models translate into concrete regulatory practices; for instance, Japan’s approach requires a license and continuous supervision for space-resource activities. The emphasis on safety zones and consistent licensing processes underscores the need for measurable, enforceable coordination mechanisms that can operate across different legal environments.

Technology, Data, and Standards for Cooperation

International cooperation in space relies on shared technologies, interoperable data practices, and common standards that enable multiple actors to plan, execute, and sustain complex missions. Collaborative efforts have historically allowed partners to pool resources, leverage diverse expertise, and diffuse risk, thereby expanding the scope and pace of scientific discovery and technological innovation. Key examples include high-profile partnerships such as the James Webb Space Telescope collaboration between ESA and NASA, whose success has underscored the value of aligning technical objectives and governance across national programs. A central pillar of cooperative space activity is the development and adoption of shared data infrastructures and access policies. Data-sharing arrangements enhance space situational awareness, trajectory calculations, and programmatic decision-making by integrating observations and monitoring capabilities across partner networks. As space activities become more data-intensive, there is growing emphasis on transparent data dissemination to support mutual security and scientific progress, while balancing national interests and commercial considerations. International bodies and national space agencies increasingly emphasize open or well-governed data platforms that enable researchers to access instruments, mission data, and observational results in standardized formats. Standards and governance frameworks underpin effective cooperation by clarifying rights, responsibilities, and procedures among partners. The International Telecommunication Union (ITU) has codified principles for the equitable and efficient use of radio frequencies and orbital resources, recognizing the finite nature of the geostationary-satellite orbit and the need to address developing country needs and geographical considerations. In space operations, clear rules of cooperation are viewed as essential to proactively address potential conflicts and uncertainties around access and activities in shared environments such as the International Space Station and beyond. Discussions about space traffic management illustrate the tension between cooperative aims and national security or economic competitiveness, highlighting that any enduring framework must balance access, autonomy, and governance authority while avoiding premature or overreaching mandates. Planetary protection and contamination control represent another domain where international standards shape cooperation. COSPAR guidelines, which classify mission risk and require protective plans for forward contamination, ensure that collaborative missions do not jeopardize the scientific integrity of celestial bodies or Earth’s biosphere, thereby enabling responsible data collection and reuse across borders. In practice, mission design and implementation decisions often occur early in the lifecycle, with partners negotiating how data rights, instrument sharing, and joint analyses will be integrated into the mission architecture from the outset. Emerging governance models for resource utilization and data sovereignty further illustrate the need for interoperable technology, transparent data practices, and agreed-upon standards. Open data platforms, shared interfaces for instrument data, and collaborative tools are commonly pursued through programmatic cooperation (whether through instrument-on-instrument sharing on satellites or data exchanges derived from climate, weather, or lunar studies) to lower barriers to information exchange and enhance collective understanding. As space activities evolve, ongoing dialogue about standards, data rights, and governance is expected to shape how technology and information are used to enable peaceful, cooperative space exploration.

Economic and Strategic Considerations

The commercial exploration and exploitation of space resources is driven by significant economic prospects, with estimates suggesting the potential profitability of asteroid mining could reach trillions of dollars, thereby creating a strong incentive for both national and corporate actors to compete and collaborate in different configurations. As in terrestrial industries, investors seek legal security and predictable frameworks to underpin large-scale, high-risk investments, given the substantial capital required for space mining and the high-stakes environment in which it operates. This mix of financial potential and risk underscores the need for dispute prevention and settlement mechanisms to manage access, safety, and competitive tensions that may arise among operators in outer space. Strategically, there is a recognition that governance gaps can hinder investment and the development of in-space industrial capabilities. A recognized path forward involves establishing prioritized mission planning and resource-conservation mechanisms that account for the physical characteristics of celestial bodies and the avoidance of resource depletion and environmental harm, signaling a shift toward more deliberate international coordination. The broader concept of benefit-sharing (including non-monetary and developmental forms such as technology transfer, capacity-building, and potentially international funds) emerges as a framework to incentivize investment while addressing equity concerns, particularly for developing countries, and to align space activities with sustainable development goals. However, officials stress that benefit-sharing should not stand in isolation from access issues and the need for robust property rights and data dissemination regimes to attract sustainable investment. Various proposals contemplate how governance could evolve in the absence of comprehensive binding treaties. Some scholars advocate for a mixed regime of legal agreements and codes of practice to regulate space resource activities, reflecting a shift away from traditional treaty-based norms toward more flexible, practice-based international cooperation that can still provide predictability for investors and operators . At the same time, there is concern that any new frameworks must address unequal access and ensure equity so that the benefits of space mining do not accrue only to a privileged few, reinforcing the argument for international coordination and shared norms as a prerequisite for scalable, long-term space exploitation. Overall, economic viability and strategic stability in space resource activities appear to depend on cooperative mechanisms that reduce uncertainty, clarify rights, and promote inclusive participation across both state and non-state actors.

Environmental and Ethical Considerations

Environmental and ethical considerations surrounding space resource exploration arise from concerns about planetary protection, environmental impact, and the broader implications for life and governance. Planetary protection aims to prevent forward contamination of celestial bodies with terrestrial biological material and backward contamination of Earth’s biosphere, a challenge that grows with private and international actors entering space activities and resource extraction. International guidelines, such as COSPAR’s review and categorization processes, seek to minimize contamination risks while enabling scientific inquiry, reflecting the tension between exploration and preservation. The broader environmental implications extend to Earth as well, where resource depletion, ecological damage from mining, and the need for sustainable practices motivate interest in alternative sources such as space resources; however, current policy frameworks lack comprehensive rules to regulate in-situ extraction or to address cross-border environmental concerns. Ethical debates emphasize balancing human advancement with responsibility to ecosystems on Earth and in space. Some argue for expanding the ethical framework to prevent transferring planetary damage into the cosmos, suggesting that recycling and sustainable practices on Earth may reduce the perceived need to mine extraterrestrial resources. Others advocate for space resource utilization as a potential path to alleviate Earth-bound resource pressures, while acknowledging that without robust international cooperation and governance, exploitation could raise issues of equity, safety, and governance under the Outer Space Treaty. Policy gaps further complicate ethical deliberations. The lack of a clear, internationally agreed regime governing space resource activities, including authorization, supervision, and area-based safety measures such as safety zones around resource sites, raises questions about environmental responsibility and equitable access while ensuring safety and non-harmful interference with ongoing operations. Proposals for international cooperation emphasize the need for clear rules of cooperation, ongoing supervision, and mechanisms to manage access and potential conflicts, highlighting that environmental stewardship and ethical considerations are integral to the sustainable exploration and development of space resources.

Security, Stability, and Risk Management

The exploration and utilization of space resources raise fundamental security and stability concerns that demand international cooperation. As you embark on resource extraction beyond Earth, the obligation not to cause environmental damage or interference with the activities of others becomes central to maintaining a stable operating environment; this is echoed in the international environmental law tradition, which emphasizes preventing transboundary harm and safeguarding shared spaces. In practice, this has translated into calls for dispute prevention and settlement mechanisms to avert escalation when activities in space generate tensions between actors, such as competing operators limiting access to an area for safety or other reasons. A key component of risk management is the establishment of area-based safety measures, such as safety zones around identified space resource activities, while preserving free access for other operators in accordance with international law. The aim is to assure safety and avoid harmful interference, with the possibility of temporary restrictions announced publicly and justified by safety considerations. This approach aligns with ongoing discussions about non-appropriation and the balance between security and free access in outer space. Debates on safety zones also intersect with liability and governance questions, including how to handle potential damages arising from debris removal and other ADR activities. The management of debris and the liability framework surrounding space operations are critical to risk mitigation. Active debris removal (ADR) poses significant legal and economic challenges because space objects are typically under the jurisdiction of their registrant states, which necessitates government permission and accountability for damages during ADR operations; establishing international norms (such as transfer-of-ownership arrangements or liability conventions) could reduce uncertainty and facilitate cooperative debris-removal efforts. Moreover, the absence of a comprehensive international debris regime has amplified calls for multilateral dialogue and cooperative missions to reduce costs and align expectations across states and commercial actors. Regulatory gaps further complicate risk management. Space mining currently suffers from limited regulation, creating opportunities for conflict and misalignment among diverse actors; this underscores the need for an overarching framework that can reconcile competing interests while safeguarding shared space uses. Some scholars and policymakers advocate for a hybrid approach that preserves top-down rulemaking where appropriate and fosters bottom-up deliberation through international forums and working groups, such as The Hague’s Building Blocks and related activities, to develop norms and governance mechanisms for space resource activities. These efforts aim to establish clear rules for safety, liability, and non-appropriation that can be implemented in practice. A coherent risk-management regime for space resources would likely integrate environmental protection principles, security considerations, and liability arrangements into an implementable framework. The literature notes that the problem is not only theoretical but hinges on practical implementation, how safety zones and other measures are designed, communicated, verified, and enforced in ways that do not unduly hamper legitimate activity while preserving space as a global commons. In this context, international cooperation remains essential to align national policies with shared norms, reduce uncertainty for operators, and mitigate the potential for conflict as more actors enter the space-resource arena.

Case Studies

The following case studies illustrate how international cooperation has shaped the governance of space resource activities and the broader exploration regime, highlighting both voluntary norms and treaty-based constraints.

  • Artemis Accords as a framework for cooperative norms and private sector participation. The Artemis Accords are a series of agreements spearheaded by the United States and first signed on October 13, 2020 by Australia, Canada, Italy, Japan, Luxembourg, the United Arab Emirates, the United Kingdom, and the United States. The Accords articulate and reaffirm principles from space treaties and operationalize norms such as peaceful exploration, transparency, interoperability, emergency assistance, registration of space objects, release of scientific data, preservation of heritage, extraction of space resources in compliance with the Outer Space Treaty (OST), deconfliction of activities, and reduction of orbital debris. As of April 2024, 39 countries had signed the Accords, though two major space-faring nations (China and Russia) are not among them. These provisions illustrate how case-by-case or treaty-norm-based cooperation seeks to align public and private actors within an agreed framework. 
  • Benefit-sharing debates under the Outer Space Treaty. The OST’s “common benefit principle” has been interpreted in divergent ways. Some scholars (e.g., Lee) advocate a binding, positive obligation on all State Parties to share benefits derived from space activities, potentially pushing toward equitable distribution of all space-derived benefits. Others view the principle as expressing a general desirability that activities be beneficial without imposing a direct obligation to share benefits. This dual interpretation underscores a key area where international cooperation faces practical hurdles, since benefit-sharing in outer space depends on the voluntary choices of space actors rather than a uniform, compulsory mechanism.
  • The Artemis Accords and questions of sovereignty and appropriation. The Accords affirm that resource extraction does not inherently constitute national appropriation, addressing a contentious interpretation of the OST’s provisions on sovereignty. However, the precise meaning of national appropriation in resource-extracting activities remains to be fully determined, illustrating how case-specific instruments grapple with applying treaty concepts to emerging activities. 
  • The International Space Station as a governance ecosystem. The ISS partnership exemplifies a long-running, multi-actor collaboration that coordinates scientific objectives with coordinated legal and administrative arrangements. The partnership works to maximize the platform’s potential and to align diverse national interests, a model often cited in discussions of how to structure cooperation in space research and resource exploration. 
  • Intergovernmental cooperation frameworks and responsibility for activities. The governance of space activities frequently involves international intergovernmental organizations and their participation under the OST framework. The arrangement permits activities conducted jointly within the framework of such organizations, with Article VI and Article XIII addressing responsibility for those activities, illustrating how states navigate organizational cooperation while maintaining accountability for space endeavors. 
  • Governance in practice: licensing and national regimes. Some jurisdictions have implemented licensing schemes to regulate space resource activities, such as that described in national contexts, where a licensing system enables the conduct of licensed activities under specific regulatory frameworks. These practical regulatory approaches show how states attempt to translate international norms into domestic regimes that can accommodate commercial participation while complying with treaty constraints. 
  • Ongoing debates on space security and weapons in orbit. International debates continue regarding proposals to ban or constrain anti-satellite weapons, with proposals at the United Nations and related bodies seeking verifiable and enforceable limitations to prevent weaponization that could create debris and destabilize space activities. These discussions reflect a broader concern that international cooperation must address both peaceful uses and the security implications of dual-use technologies in space. 

Future Directions

Looking ahead, the development of space resource activities is likely to move away from purely formal treaty regimes toward cooperative norm-building and multi-stakeholder governance. The United Nations Committee on Peaceful Uses of Outer Space established a Working Group on Legal Aspects of Space Resource Activities to draft general principles guiding future activity, with a draft set of recommended principles presented in May 2025. These principles emphasize peaceful exploration, safety, sustainability, and environmental protection for both Earth and outer space, signaling a shift toward internationally agreed norms as a basis for subsequent rules and potential formal adoption. A parallel track has emerged through the Hague International Space Resources Governance Working Group, which since 2016 has influenced norm-building and outlined a space mining framework that foregrounds benefit sharing. Scholars and policymakers argue that an international agreement anchored in broadly accepted norms, or a formal convention upholding the Outer Space Treaty, offers the most effective path to achieving equity in space mining. Such an agreement could provide the legal clarity and legitimacy necessary for investment and industrial development, complementing ongoing norm-based efforts. The literature also highlights a spectrum of governance options, ranging from endorsement of new international instruments to potential incorporation within an overarching treaty framework or the Moon Agreement as an Article 11 resource regime. To bolster investment and operational certainty, there is consideration of establishing dedicated international bodies or authorities analogous to the International Telecommunication Union or the International Seabed Authority, capable of securing a stable regime for space resources. At the same time, many stakeholders advocate for mechanisms that incentivize technology development, capability-building, and education (particularly in developing countries) through non-monetary forms of benefit-sharing or international funds tied to sustainable development goals. These mechanisms would need to be harmonized with access and property-right considerations to avoid bottlenecks and to support broad participation in ISRU activities. In sum, future directions point toward a hybrid governance model that blends normative frameworks with formal international instruments, supported by targeted mechanisms for benefit-sharing and investment incentives. The aim is to create a predictable, safe, and peaceful regime that can accommodate diverse national approaches while ensuring equitable benefit distribution and robust environmental protections, thereby enabling scalable cooperation in the exploration, exploitation, and utilization of space resources. Some scholars argue that expanding the mandate of existing bodies, such as the ITU, to cover physical space resources could provide the most cohesive and legally coherent path to a rules-based regime, though practical implementation remains a subject of ongoing debate.
