The Registration Convention was considered and negotiated by the Legal Subcommittee from 1962. It was adopted by the General Assembly in 1975(General Assembly resolution 3235 (XXIX)) and entered into force on 15 September 1976.
Building upon the desire expressed by States in the Outer Space Treaty, the Rescue Agreement and the Liability Convention to make provision for a mechanism that provided States with a means to assist in the identification of space objects, the Registration Convention expanded the scope of the United Nations Register of Objects Launched into Outer Space that had been established by resolution 1721B (XVI) of December 1961 and addressed issues relating to States Parties responsibilities concerning their space objects. The Secretary-General was, once again, requested to maintain the Register and ensure full and open access to the information provided by States and interntional intergovernmental organizations.
