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. A significant change in the approach to orbital rescues came in the wake of the Space Shuttle Columbia disaster, after NASA took steps to prepare the STS-3x or Launch on Need missions to ensure rescue in certain scenarios.  However, this capability was never exercised during the remainder of the space shuttle program. 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 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 agreement on the rescue of astronauts, the return of astronauts and the return of objects that have been launched into space, also known as the rescue agreement, is an international agreement that defines the rights and duties of states with regard to the rescue of 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 agreement also does not take into account the cost of a rescue mission. 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. However, the cost of rescuing astronauts is not mentioned in the agreement. The rescue agreement provides clear clarity by referring to “spaceship personnel” and not “astronauts.” But this sentence once again leaves it uncertain whether someone who is content to travel, such as a tourist on a Virgin Galactic flight, would be considered part of the personnel of a spaceship. In the event that a space object or its parts land on the territory of another contracting country, the state in which the object lands (at the request of the original entity) is required to recover the space object and return it to the original authority.
