• Agreement on the Rescue of Astronauts, the Return of Astronauts and the Return of Objects Launched into Outer Space (London, Moscow, Washington D.C., 22 April 1968)
• Convention on International Liability for Damage Caused by Space Objects (London, Moscow, Washington, D.C., 29 March 1972)
• Convention on Registration of Objects Launched into Outer Space (New York, 14 January 1975)
• Moon Treaty, Agreement Governing the Activities of States on the Moon and Other Celestial Bodies (New York, 5 December 1979)

UN Declarations and Resolutions

The resolutions and decisions of the United Nations General Assembly and Security Council may provide valuable information on outer space activities and space law. Although they cannot themselves constitute international law or serve as conclusive evidence of a rule of customary law, such resolutions do have value in providing evidence of existing or emerging law. This point of view has been acknowledged by the International Law Commission.

As every Member State has been recognized and has a vote in the UN General Assembly, finding General Assembly resolutions that passed unanimously or near-unanimously may serve as an excellent starting point in the legal research process. Pay attention to the language of the resolution. Those with firm obligations versus those that are merely aspirational or advisory in nature are more likely to be considered valuable as evidence of customary international law.
