The Agreement on the Rescue of Astronauts, the Return of Astronauts and the Return of Objects Launched into Outer Space — commonly called the Rescue Agreement — was adopted by the UN General Assembly on 19 December 1967 and opened for signature on 22 April 1968, entering into force on 3 December 1968. It elaborates Articles V and VIII of the 1967 Outer Space Treaty (OST), translating their general principles into operational duties.
The Agreement is structured around a small set of obligations:
- Notification (Article 1): A state that learns astronauts are in distress, have made an emergency or unintended landing, or have alighted on its territory or the high seas must immediately notify the launching authority and the UN Secretary-General.
- Assistance on land (Articles 2–3): If personnel land on a state's territory, that state must take all possible steps to rescue them; if they come down on the high seas or in a place not under any state's jurisdiction, parties in a position to help "shall extend assistance in search and rescue operations" as necessary.
- Prompt return (Article 4): Astronauts are to be "safely and promptly" returned to representatives of the launching authority. Notably, the treaty contains no reciprocity condition and no provision for detention or interrogation.
- Return of space objects (Article 5): Recovered objects or component parts found beyond the launching state's territory must be returned on request, with recovery expenses borne by the launching authority. States must also notify the launching authority of hazardous objects.
The Agreement is administered through the UN Office for Outer Space Affairs (UNOOSA) and the Committee on the Peaceful Uses of Outer Space (COPUOS). It treats astronauts as "envoys of mankind," echoing the OST's humanitarian framing.
Debates persist over whether the term "personnel of a spacecraft" extends to private-sector spaceflight participants and space tourists — a gap that has gained relevance with the rise of commercial human spaceflight. The Agreement also does not define "launching authority" precisely, which can complicate cases involving multinational missions or transferred ownership of satellites.
Example
In January 2018, when debris from China's Long March 3B rocket fell in northern Myanmar, the Rescue Agreement framework governed expectations around notification and return of the recovered components to the launching state.
Frequently asked questions
The OST sets the principle that astronauts are envoys of mankind and must be assisted; the Rescue Agreement spells out the concrete procedures for notification, search and rescue, and return of personnel and objects.
