Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies (Outer Space Treaty)

Opened for signature: 27 January 1967.
Entered into force: 10 October 1967.
Number of Parties: 96 States. Number of Signatories: 27 States.
Depositories: Russia, UK, and U.S..

The Outer Space Treaty was adopted by the General Assembly in its resolution 2222 (XXI) after it had been considered by the Legal Subcommittee in 1966. The Treaty was largely based on the Declaration of Legal Principles Governing the Activities of States in the Exploration and Use of Outer Space, which had been adopted by the General Assembly in its resolution 1962 (XVIII) in 1963, but added a few new provisions.

Treaty obligations: exploration and use of outer space shall be carried out for the benefit and in the interest of all countries, and it shall be the province of mankind; not to place in orbit around the Earth any objects carrying nuclear weapons or any other kinds of weapons of mass destruction; not to install such weapons on celestial bodies, or station them in outer space in any other manner; the moon and other celestial bodies are to be used exclusively for peaceful purposes; establishment of military bases, installations and fortifications, the testing of any type of weapons, and the conduct of military maneuvers on celestial bodies shall be forbidden.

Verification: all stations, installations, equipment, and space vehicles on the moon and other celestial bodies shall be open to representatives of other states parties on a basis of reciprocity; such representatives shall give reasonable advance notice of their projected visit, in order that appropriate consultations may be held, and that maximum precautions may be taken to assure safety and to avoid interference with normal operations of the facility to be visited.

Consideration by the UNGA of further measures for preventing an arms race in outer space: In 1993, a UN study on the application of confidence-building measures in outer space was concluded and submitted to the UNGA (48/305), pursuant to its resolution of December 1990. The group of governmental experts commissioned to prepare the study concluded that since the Outer Space Treaty was adopted in 1967, "legal norms may have to be developed further, whenever appropriate, to address new developments in space technology and increasing universal interest in its application." Thus, the need to formulate a framework for the enhancement of cooperation and confidence-building among states was identified. The 1993 regular session of the UNGA commended this study to the attention of all UN members (48/74B).

The 1994 regular session of the UNGA reaffirmed that there is a need to consolidate and reinforce the legal regime applicable to outer space; emphasized the necessity of further measures with appropriate and effective provisions for verification; and requested the CD to intensify its consideration of the question of the prevention of an arms race in outer space in all its aspects (49/74).

The 1995 and 1996 regular sessions of the UNGA again affirmed the need to consolidate the regime, and requested that the CD re-establish an ad hoc committee on the subject (50/69).

During the 1997 UNGA adopted a resolution aimed at the prevention of an arms race in Outer Space (52/37), which reaffirmed the importance and urgency of preventing an international arms race in outer space and the readiness of all States to contribute to that common objective. The 1998 resolution (53/76) reiterated the former and emphasized the need for further measures, with verification, to prevent an arms race. The resolution stated that the CD has the primary role in negotiating multilateral agreements, including on the prevention of an arms race in outer space. It also called for the re-establishment of the ad hoc committee of the CD. Furthermore, it urged States that conduct activities in outer space to keep the CD updated on any progress on bilateral or multilateral negotiations on the matter. The UNGA resolution of 1999 (54/53) reiterated the above objectives, while calling for the re-establishment of the ad hoc committee of the CD in 2000.
