Introduction. Space Diplomacy: The Final Frontier of Theory and Practice

Abstract

Summary A quantum leap is under way in space as a domain of human activity. The global space economy has rapidly reached almost USD450 billion in size and is projected to grow to over USD1 trillion by the 2040s. There are hundreds of actors involved, from space agencies to private companies to start-ups. Over 70 countries have space programmes and 14 have launch capabilities. These developments have involved intense transnational and international co-operation and competition, across both the public and private sectors. With such rapid changes underway, this article takes stock of how these developments impact international relations. Overall, this is the first special issue in the field of international relations to use theories of diplomacy to bring to light the various ways in which experts, scientists, astronauts, space enthusiasts and professional diplomats, among others, have shaped the formal and informal interactions among states in this key area of foreign policy.
