How International Treaties Protect Celestial Bodies: A View from the Majority World

When we talk about protecting celestial bodies, we aren’t just discussing the preservation of distant rocks and ice. We’re wrestling with a deeper question: who gets to decide the future of the Moon, Mars, and the asteroids, and on what terms? For many nations in Africa, Latin America, Southeast Asia, and the small island developing states, this isn’t an abstract legal puzzle. It’s about economic survival, scientific parity, and preventing a new colonial order from taking root beyond Earth’s atmosphere. The treaties that govern outer space are the only tools we currently have to ensure the cosmos doesn’t become a playground for the powerful, but rather a shared heritage governed by law, not by might.

The existing framework, anchored by the 1967 Outer Space Treaty (OST), sets a baseline. It prohibits national appropriation, mandates that space be used for the benefit of all countries, and bars weapons of mass destruction in orbit. For many in the Global South, these principles feel like a half-built house. The treaty protects celestial bodies from sovereign claims, but it’s conspicuously silent on the extraction of resources by private companies. This gap is the central tension of modern space law, a void that threatens to render the treaty’s noble intentions meaningless for nations that lack the capital to launch their own mining missions.

The Outer Space Treaty: A Shield with a Hole

The OST is often called the Magna Carta of space. Its Article II is crystal clear: “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.” This provision was a direct response to Cold War fears of a territorial land grab on the Moon. It effectively bans any country from planting a flag and declaring a lunar crater its own. For non-spacefaring nations, this is a vital, non-negotiable safeguard. It guarantees that their lack of a launchpad doesn’t translate into a lack of legal standing.

But the treaty’s silence on resource extraction has become deafening. Article I says space shall be free for exploration and use by all States, but does “use” include mining and selling what you find? The United States, through its 2015 Commercial Space Launch Competitiveness Act, and Luxembourg, with its 2017 Space Resources Act, have unilaterally answered “yes,” granting property rights to resources extracted by their citizens. This legislative interpretation, while not claiming sovereignty over the land itself, creates a de facto property regime that mirrors the historical “first-come, first-served” logic of colonial expansion. For a country like Nigeria, which has a growing space program but no near-term capacity for lunar mining, this approach risks building a system where the law protects the land but not the wealth it holds.

The Moon Agreement: A Path Not Taken

The 1979 Moon Agreement tried to close this loophole. Its Article 11 declares the Moon and its natural resources to be the “common heritage of mankind,” a concept borrowed from the Law of the Sea. It calls for an international regime to govern resource exploitation, ensuring equitable sharing of benefits, with special consideration for developing countries. The logic was straightforward: if the Moon’s resources are a common heritage, no single nation or corporation should be allowed to monopolize them before a fair governance system is in place.

Yet, the Moon Agreement has been ratified by only 18 states, none of which are major spacefaring powers. Why? The common heritage principle, while morally compelling, is seen by some as a moratorium on commercial activity. It demands a level of international consensus and wealth redistribution that powerful nations and their private sectors have been unwilling to accept. For many in the Global South, this rejection is a profound disappointment. It signals that the international community is willing to protect celestial bodies from national flags, but not from corporate extraction. The result is a legal vacuum, where the absence of a ratified regime is being filled by national legislation that prioritizes the interests of those who can get there first.

Planetary Protection and the Biosphere Bias

Another layer of protection, often overlooked in policy debates, is planetary protection. This isn’t about preventing resource exploitation, but about preventing biological contamination. The OST’s Article IX requires states to avoid “harmful contamination” of celestial bodies. This principle is operationalized through the Committee on Space Research (COSPAR) Planetary Protection Policy, which categorizes missions based on their target body’s potential for life.

For a nation like the Seychelles, a small island state deeply invested in the Blue Economy and vulnerable to climate change, the logic of planetary protection resonates. It’s a precautionary principle applied to the cosmos. However, the current framework is heavily biased toward protecting potential Martian biospheres for scientific study. It says little about protecting the pristine environments of celestial bodies for their own sake, or about the ethical and cultural dimensions of altering a landscape that has existed for billions of years. As more actors, including those from Africa and Asia, develop lunar missions, the conversation must expand beyond the narrow lens of Western astrobiology to include broader environmental ethics and the rights of future generations to inherit an unspoiled solar system.

The Artemis Accords: A Parallel Regime

The Artemis Accords, signed by over 30 nations as of 2024, represent a significant shift in how celestial bodies are governed. They are not a treaty but a set of bilateral agreements with the United States, operationalizing principles for lunar exploration. They explicitly endorse space resource extraction, framing it as permissible under the OST. The Accords also introduce the concept of “safety zones” around lunar operations, which, while temporary, raise concerns about de facto exclusion and the potential for a patchwork of claimed areas on the Moon.

For signatories like Rwanda and Nigeria, the Accords offer a seat at the table and a framework for collaboration. Yet, the Accords are not a universally accepted standard. Major space actors like China and Russia have not signed, and the legal community remains divided on whether the Accords’ interpretation of resource rights is consistent with the OST. This creates a fragmented governance landscape, where the protection of celestial bodies depends on which club you belong to. A more effective, multilateral approach, perhaps through the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS), is essential to prevent a bifurcated legal order that leaves the majority of nations without a voice.

Institutional Design for the Next Generation

So, what does a just and effective protection regime look like? It must move beyond the binary of “no sovereignty” versus “free mining.” We need institutional designs that are adaptive, inclusive, and grounded in the realities of asymmetric capabilities. One model is an international registry for space resources, where all extraction activities are transparently logged, and a portion of the proceeds is channeled into a global fund for sustainable development. This would not stifle innovation but would ensure that the benefits of celestial resource use are shared, as the OST originally envisioned.

Another critical element is the active participation of nations from Africa, Latin America, Southeast Asia, and small island states in the standard-setting bodies. Currently, technical standards for lunar operations are often developed by established space agencies and industry consortia, with limited input from the majority world. This can lead to standards that inadvertently exclude or disadvantage emerging space programs. A truly protective regime must be co-designed, not just presented for ratification. It must also address the specific concerns of equatorial nations, which host vital launch infrastructure, and small island states, which face existential threats from climate change and see space-based Earth observation as a lifeline.

Practical Steps and Current Context

The urgency is not theoretical. The rush to establish a permanent lunar presence is accelerating, with both state-led and commercial missions planned for the coming decade. The International Space Station’s planned decommissioning around 2030 will shift focus to lunar orbit and surface habitats. Without clear, equitable rules, we risk a “scramble for the Moon” that mirrors the worst chapters of terrestrial history. The protection of celestial bodies is not just about preserving craters; it is about preserving the principle that space is a shared domain, governed by law, not by power.

For policymakers in Abuja, Jakarta, or Suva, the immediate task is to build technical and legal capacity. This means investing in space law expertise, actively participating in COPUOS working groups, and forming coalitions with like-minded states to advocate for a multilateral resource governance framework. It also means engaging with the private sector to ensure that national space policies align with international obligations. The treaties are not self-executing; they require constant, informed vigilance to remain effective.

Frequently Asked Questions

Does the Outer Space Treaty ban all commercial activity on the Moon?

No. The Outer Space Treaty does not prohibit commercial activity. It prohibits national appropriation of territory but is silent on the extraction and sale of resources. This ambiguity has led to national laws, like those in the U.S. and Luxembourg, that permit private companies to own and sell resources they extract. The legality of these laws under the OST is a subject of ongoing international debate, with many states arguing that such unilateral actions violate the treaty’s principle that space should benefit all countries.

What is the “common heritage of mankind” and why is it controversial?

The “common heritage of mankind” is a legal principle that designates certain areas and resources as belonging to all humanity, to be managed collectively for the benefit of all, with special consideration for developing countries. It was applied to the deep seabed in the Law of the Sea and to the Moon in the 1979 Moon Agreement. It is controversial because it implies that no single nation or company can claim exclusive rights to resources, and that an international body must regulate exploitation and distribute benefits. Major spacefaring nations have rejected this as a barrier to commercial investment and innovation.

How can a country with no space program help protect celestial bodies?

Protection is not solely about physical presence. Non-spacefaring nations play a critical role in shaping the legal and normative framework through multilateral forums like the UN Committee on the Peaceful Uses of Outer Space (COPUOS). By building coalitions, submitting working papers, and advocating for equitable treaty interpretation, these states can influence the development of binding norms. They can also use their diplomatic weight to demand transparency and benefit-sharing mechanisms in bilateral agreements like the Artemis Accords, ensuring that the interests of all humanity are represented in the governance of celestial resources.

What are “safety zones” and why are they a concern?

Safety zones, as outlined in the Artemis Accords, are temporary areas established around lunar operations to prevent harmful interference. While practical for avoiding collisions and dust contamination, critics worry that these zones could become de facto exclusion zones, creating a patchwork of claimed areas that undermine the Outer Space Treaty’s non-appropriation principle. The size, duration, and notification requirements for these zones are still being defined, and their implementation will be a key test of whether the Accords can coexist with a truly multilateral governance framework.

Looking Ahead: A Recurring Column on Treaty Implementation

This article marks the beginning of a recurring column on cosparhq.org, where we will track the implementation gaps in international space law, with a specific focus on how these gaps affect the agency of nations in the Global South. In our next installment, we will examine the role of the International Telecommunication Union in allocating orbital slots and spectrum rights, a quiet but fierce battleground for digital sovereignty. The protection of celestial bodies is not a single treaty article; it is a continuous process of negotiation, interpretation, and, when necessary, resistance. The stars belong to no one, but the rules for reaching them must belong to all of us.

The image of our planet hanging in the blackness of space, as seen from the lunar surface, is a stark reminder of our shared vulnerability and collective responsibility. The treaties that protect celestial bodies are not just legal documents; they are a reflection of our capacity to govern beyond borders, to choose cooperation over competition in the face of the infinite.

Effective protection of the Moon and other bodies requires a dynamic, inclusive multilateralism. The negotiating tables at the United Nations in Vienna, where space law is shaped, must reflect the full diversity of our planet. Only then can we ensure that the rules are not written by the few for the many, but are a genuine product of global consensus.
