The requirement for international standards for rescue and return of distressed astronauts rapidly assumed importance in the first years of the space age, paralleling development of the technology necessary to sustain man in outer space and to permit re-entry of spacecraft through the earth’s atmosphere. The need increased in the early 1960’s when both the United States and the Soviet Union announced inauguration of space flight programs to send men to the moon and return them to earth. It was recognized that, in the continued absence of any firm international consensus on this subject, international friction could be caused by disagreement over procedure to be followed, the nature and extent of states’ obligations, or by differences in interpreting or applying legal principles in the event earth or space rescue and return operations became necessary. These conditions (possible unintentional misunderstanding during manned flight emergencies, swift developments in astronautical science and technology that made manned space flight a reality, and the importance of astronauts in terms of national prestige and subsequent status as “envoys of mankind”) combined to encourage international agreement upon standards for rescue and return by way of direct discussion among states, informal agreement, and, ultimately, conclusion of formal conventions governing this activity; and they discouraged reliance by nations upon principles or practices derived from custom and precedent.
