Outer Space Treaty

The Outer Space Treaty, formally the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, is a treaty that forms the basis of international space law. The treaty was opened for signature in the United States, the United Kingdom, and the Soviet Union on 27 January 1967, and entered into force on 10 October 1967. As of June 2020, 110 countries are parties to the treaty, while another 23 have signed the treaty but have not completed ratification.[1] In addition, Taiwan, which is currently recognized by 14 UN member states, ratified the treaty prior to the United Nations General Assembly's vote to transfer China's seat to the People's Republic of China (PRC) in 1971.[5]

Outer Space Treaty of 1967 at Wikisource

Among the Outer Space Treaty's main points are that it prohibits the placing of nuclear weapons in space, limits the use of the Moon and all other celestial bodies to peaceful purposes only, and establishes that space shall be free for exploration and use by all nations, but that no nation may claim sovereignty of outer space or any celestial body. The Outer Space Treaty does not ban military activities within space, military space forces, or the weaponization of space, with the exception of the placement of weapons of mass destruction in space, and establishing military bases, testing weapons and conducting military maneuvers on celestial bodies.[6][7] It is mostly a non-armament treaty and offers limited and ambiguous regulations to newer space activities such as lunar and asteroid mining.[8][9][10]

Key pointsEdit

The Outer Space Treaty represents the basic legal framework of international space law. Among its principles, it bars states party to the treaty from placing weapons of mass destruction in Earth orbit, installing them on the Moon or any other celestial body, or otherwise stationing them in outer space. It specifically limits the use of the Moon and other celestial bodies to peaceful purposes, and expressly prohibits their use for testing weapons of any kind, conducting military maneuvers, or establishing military bases, installations, and fortifications (Article IV). However, the treaty does not prohibit the placement of conventional weapons in orbit, and thus some highly destructive attack tactics, such as kinetic bombardment, are still potentially allowable.[11] The treaty also states that the exploration of outer space shall be done to benefit all countries and that space shall be free for exploration and use by all the states.

The treaty explicitly forbids any government from claiming a celestial body such as the Moon or a planet.[12] Article II of the treaty states 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 occupation, or by any other means." However, the state that launches a space object retains jurisdiction and control over that object.[13] The state is also liable for damages caused by its space object.[14]

Being primarily an arms-control treaty for the peaceful use of outer space, it offers insufficient and ambiguous regulations to newer space activities such as lunar and asteroid mining.[8][10][15] It therefore remains under contention whether the extraction of resources falls within the prohibitive language of appropriation or whether the use encompasses the commercial use and exploitation.[16] Seeking clearer guidelines, private U.S. companies lobbied the U.S. government, and space mining was legalized in 2015 by introducing the US Commercial Space Launch Competitiveness Act of 2015.[17] Similar national legislation to legalize the appropriation of extraterrestrial resources are now being introduced by other countries, including Luxembourg, Japan, China, India, and Russia.[8][15][18][19] This has created some controversy regarding legal claims over the mining of celestial bodies for profit.[15][16]

Responsibility for activities in spaceEdit

Article VI of the Outer Space Treaty deals with international responsibility, stating that "the activities of non-governmental entities in outer space, including the Moon and other celestial bodies, shall require authorization and continuing supervision by the appropriate State Party to the Treaty" and that States Parties shall bear international responsibility for national space activities whether carried out by governmental or non-governmental entities.

As a result of discussions arising from Project West Ford in 1963, a consultation clause was included in Article IX of the Outer Space Treaty: "A State Party to the Treaty which has reason to believe that an activity or experiment planned by another State Party in outer space, including the Moon and other celestial bodies, would cause potentially harmful interference with activities in the peaceful exploration and use of outer space, including the Moon and other celestial bodies, may request consultation concerning the activity or experiment."[20][21]

Follow-upsEdit

The United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) coordinates[23] these treaties and other questions of space jurisdiction.

List of partiesEdit

The Outer Space Treaty was opened for signature in the United States, the United Kingdom, and the Soviet Union on 27 January 1967, and entered into force on 10 October 1967. As of June 2020, 110 countries are parties to the treaty, while another 23 have signed the treaty but have not completed ratification.[1]

Multiple dates indicate the different days in which states submitted their signature or deposition, which varied by location. This location is noted by: (L) for London, (M) for Moscow, and (W) for Washington, DC. Also indicated is whether the state became a party by way of signing the treaty and subsequent ratification, by accession to the treaty after it had closed for signature, or by succession of states after separation from some other party to the treaty.

Partially recognized state abiding by treatyEdit

The Republic of China (Taiwan), which is currently recognized by 14 UN member states, ratified the treaty prior to the United Nations General Assembly's vote to transfer China's seat to the People's Republic of China (PRC) in 1971. When the PRC subsequently ratified the treaty, they described the Republic of China's (ROC) ratification as "illegal". The ROC has committed itself to continue to adhere to the requirements of the treaty, and the United States has declared that it still considers the ROC to be "bound by its obligations".[5]
