At the time of the development of the treaty, the prospect of saving space travellers was unlikely due to limited launch opportunities, even the most advanced space programs, but has become more plausible since then. For example, Mir and later the International Space Station have entertained Russian soyuz docked spacecraft that, in an emergency, will be used as a leakage mechanism; in some scenarios, this vessel could also assist in a rescue. The rescue agreement has been criticized for being vague, particularly in terms of the definition of the saved and the definition of what constitutes a spacecraft and its components. The bailout agreement essentially stipulates that any State party to the agreement must provide all possible assistance to rescue the personnel of a spaceship that has landed on the territory of that state, whether as a result of an accident, an emergency, an emergency or an accidental landing. If distress occurs in an area outside the territory of a nation, each part of the state able to do so will increase assistance in the search and rescue operation, if necessary. The agreement on the rescue of astronauts, the return of astronauts and the return of objects that have entered space is also called the Rescue Agreement, an international agreement that defines the rights and obligations of states to rescue people in space. The agreement was reached by a consensus vote at the United Nations General Assembly on 19 December 1967 (Resolution 2345 (XXII)) It came into force on 3 December 1968. Its provisions specify the rescue provisions set out in Article V of the 1967 Space Treaty. Although the bailout agreement is more specific and detailed than the rule of rescue of Article V of the Space Treaty, it still suffers from vague formulations and the possibility of differences of interpretation. The UN General Assembly adopted the text of the bailout agreement on 19 December 1967 by Resolution 2345 (XXII). The convention was opened for signature on April 22, 1968 and came into force on December 3, 1968.
Since January 2019, 98 states have ratified the bailout agreement, 23 have signed and three international intergovernmental organizations (the European Space Agency, the Intersputnik International Organization of Space Communications and the European Organization for the Use of Meteorological Satellites) have declared their acceptance of the rights and obligations conferred by the agreement.  The cost of a rescue mission is also not included in the agreement. The bailout agreement stipulates that the state of departure must bear the costs of rescuing a boat that crashes into the territory of another state.
