Elgar Research Agendas outline the future of research in a given area. Leading scholars are given the opportunity to explore their subject in provocative ways, and map out the potential directions of travel. They are relevant but also visionary. Space policy is now a top priority in international relations. This timely Research Agenda takes the definition of space policy itself as an object of analysis rather than as an unquestioned premise. It presents the multi-faceted spectrum of elements combined within space policy which are crucially relevant to security, welfare and modern society. Chapters demonstrate why space matters and how space policy research has reflected this during the past half-century. Expert international contributors set out a forward-looking research agenda for the 2020s, identifying key problems and conflicts related to the topic and exploring policy, regulatory approaches and diplomatic mechanisms to reach possible solutions. The types of actors and institutions playing a key role in space policy are also examined through an interdisciplinary lens. Scholars and students of political science, international relations and law will find this to be a sophisticated, cutting-edge resource for analysing and understanding the multi-dimensional impacts of space policy.
