Exclusivity and Rights in the Exploration of Outer Space

 

There is a general debate whether space should belong to all mankind or belong to those who have the resources to explore space.[1]  Below are some specific issues underlying this theme:

 

A.           Right to Explore Particular Areas of Space

Article I of the Agreement Governing the Activities of States on the Moon and Other Celestial Bodies (hereinafter ÒOuter Space TreatyÓ) states that outer space is open and free for exploration and use by all states.  State sovereignty does not extend to outer space.  But while this article enunciates the highest ideals of exploration for several decades, the practical reality is that few countries have the economic means to undertake the massive expenses involved in space exploration.  Further, many developed countries argue that incentives to invest in exploration cannot exist unless parties have exclusive exploration rights over particular areas of space.  Without those exclusive rights, parties would have no assurance that their investments in space exploration would be rewarded with sufficient profits.

 

B.           Sovereignty and Property Rights Over Explored Areas

Article II of the Outer Space Treaty provides that outer space, including the moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use, or by any other means.  Because no nation has sovereignty over any area of space, there is no legal basis for private parties to assert property claims over tangible goods found in outer space.  Typically, property rights do not exist unless sovereignty is also present.  But there is historical precedent for property claims to resources even without any country claiming sovereignty over the region where those resources are found.  In the 1920s, many countries mined the Spitzbergen Archipelago in the Arctic Sea without alleging sovereignty over the islands.[2]

 

The Outer Space Treaty was drafted during the Cold War when assertion of sovereignty was a more germane issue that assertion of property rights for the purpose of economic exploitation.  Some commentators have argued that the Outer Space Treaty cannot be interpreted to preclude assertion of exclusive economic rights in space.[3] 

 

While the Outer Space Treaty is sufficiently vague so that it can be interpreted to allow exclusive economic rights over particular areas of space, the Moon Treaty of 1979 clearly prohibits private ownership of areas of the moon: ÒNeither the surfaces nor subsurfaces of the moon, nor any part thereof or natural resources in place, shall become property of any State, international, intergovernmental or non-governmental organization, national organization, or non-governmental entity, or natural person.Ó  Article 5 of the treaty contemplates an international regime to govern exploitation of the MoonÕs resources.  While the treatyÕs language is strong, the treaty is of limited force because only eight countries (Australia, Austria, Chile, Mexico, the Netherlands, Pakistan, the Philippines, and Uruguay) have signed it, and none of them have a significant space program or the resources to develop such a program.

 

 

C.          Sharing Economic Wealth Flowing From Exploration

Do wealthy nations who explore space have an obligation to share the fruits of those explorations with all mankind, and in particular, developing countries that cannot afford the costs of exploring space without help from the developed countries?  Article I(1) of the Outer Space Treaty states that use of outer space shall be carried out É for the benefit and in the interests of all countries.Ó  But wealthy countries argue that an obligation to share the fruits of exploration, the most obvious examples being mineral and energy wealth, destroys their incentive to invest in space exploration.

 

D.          Analogous Areas of International Law on Earth

 

1.           Law of the Sea

United Nations discussions relating to law of the sea have developed the notion that the seabed and ocean floor are a "common heritage of mankind." The common heritage principle consisted of five essential elements:

(1) the area under consideration cannot be subject to appropriation;

(2) all countries must share in its management;

(3) there must be an active sharing of the benefits reaped from the exploitation of resources;

(4) the area must be dedicated to exclusively peaceful purposes; and

(5) the area must be preserved for future generations.

Some commentators have tried to import the Common Heritage concept from the law of the sea into the law of space.

 

2.           Law Relating to Exploration of Antarctica

In trying to enact a regime to govern lunar mining, some commentators have looked at legal proposals to govern mining in Antarctica.[4]  Under the Antarctic Treaty, activities are only governed by Consultative Parties, i.e., parties undertaking substantial scientific research in Antarctica.[5] 

 

 

Conclusion

 

Although the regime relating to space exploration has been developing for several decades, there is still no clearly articulated system of legal rights relating to exploration and economic exploitation of outer space.  The notable exception to this trend is communication satellites, where organizations such as INTELSAT and INMARSAT have successfully created a reliable legal framework.  But no clear comprehensively binding legal regime governs matters as basic as the mining of material from other celestial bodies.  The Outer Space Treaty of 1967 states basic principles concerning exploration but fails to clearly delineate a set of property or contract law principles. However, the treaty explicitly prohibits future space exploration and economic exploitation.  The Moon Treaty also offers such a prohibition, but is far more limited than the Outer Space Treaty due to the limited number of nations that signed it.  Given the lack of a coherent framework, wealthy nations with the resources to explore space and make use of its resources have few legal principles to prevent them from doing so and little obligation to share any discovered resources with the rest of the world.

General Policy Concerns of Space Law

 

The current National and International agreements, memorandums, treaties and resolutions are based on the policy of cooperative space research and exploration.  At present, the goal of space exploration is not a race to claim resources, but to further the exploration and scientific research.  A major goal is to maximize the total capacity of global space programs. 

 

It is especially clear in the memorandum (ftp://ftp.hq.nasa.gov/pub/pao/reports/1998/nasa_russian.html) between NASA and the RSA (Russian Space Agency) regarding the International Space Station that cooperation is the backbone of this particular, and all future space agreements.

 

The current agreements suggest that satellites and objects placed into orbit are subject to the jurisdiction of the party which launched them, and any international problems are to be resolved by international law and the jurisdiction of the United Nations.  The role of the UN is to promote peaceful exploration and cooperation.

 

Currently, there are no recognized property rights to any real property, natural resources or other benefits derived from space development.  However, there are many interesting proposals for developing equitable property rights on the moon, asteroids and other celestial bodies.

 

Although military satellites are permitted for many purposes, there are a variety of treaties specifically banning the placement of any weapons of mass destruction into space.  Aside from the specific weapons of mass destruction, the weaponization of space by other means is a topic of concern for many countries around the world.

 

I was unable to locate any specifics on any current laws, treaty or even serious proposals regarding interstellar law.  There simply seems to be nothing out there at this time, I guess we will have to wait until our technology improves somewhat and interstellar travel is closer to reality.

Space Law Cases

 

Smith v. United States, 507 U.S. 197 (1993)

Summary:  Smith brought a wrongful death claim against the US after her husband fell into a deep hole and was killed while near his research station in Antarctica.  The Supreme Court held the FTCA (Federal Torts Claim Act) does not apply to Antarctica because the lack of any sovereign Antarctic government excludes it from meeting the requirement as a ³foreign country² under the FTCA.  It is noted in the case and in the dissent that the situation in Antarctica parallels some of the outer space cases we will begin to see in the future.

 

United States v. One Lucite Ball Containing Lunar Material, 2003 U.S. Dist Lexis 467 (2003)

Summary: In 1973 a plaque was presented to Honduras by President Nixon which contained a moon rock retrieved by astronauts during one of the Apollo moon landings.  In 1994, the moon rock was stolen from the Honduran President and was later sold to an American by a retired Honduran colonel.  Undercover US agents were able to set up a sting and recover the moon rock.  Under the Honduran Civil code, the ³innocent owner² defense was not available and the moon rock and the plaque were forfeited to the United States.

 

This case has little to do with actual space law, but was one of the few cases I was able to find that dealt with actual space (lunar) material.  The case was interesting to me because it is so recent (filed March 24, 2003) and because of the million dollar value placed on the moon rock.

 

The recent Shuttle crash will may lead to several cases prosecuting people for tampering, stealing or interfering with the collection of the shuttle debris.  It will be interesting to see if any new aspects of space law are developed as a result.

 

I was unable to find any cases addressing the legality or any disputes involving the sale of parcels of moon land (or other celestial bodies).
