An International Journal
Space Policy is an international, interdisciplinary journal which draws on the fields of international relations, economics, history, aerospace studies, security studies, development studies, political science and ethics to provide discussion and analysis of space activities in their political, economic, industrial, legal, cultural and social contexts.
Alongside full-length papers, which are subject to a double-blind peer review system, the journal publishes opinion pieces, case studies and short reports and, in so doing, it aims to provide a forum for the exchange of ideas and opinions and a means by which authors can alert policy makers and international organizations to their views. Space Policy is also a journal of record, reproducing, in whole or part, official documents such as treaties, space agency plans or government reports relevant to the space community. Views expressed in the journal are not necessarily those of the editors or members of the editorial board.
