This book provides an in-depth investigation of the concept of space power and devises a novel conceptual framework for empirically measuring and comparing different typologies of space actors on the basis of clearly defined criteria. In turn, the book identifies a comprehensive set of conditions required to achieve and maintain the status of space power and explores the main political, security, and socio-economic stakes involved. Building on this basis, the book conducts a comparative assessment of the major space actors, the underlying aim of which is to examine Europe s relative position in the space arena and put into perspective its proclaimed goal to assert itself as a space power, with all of the means and resources this would entail. Given its scope, the book represents a valuable and versatile tool to support European decision-making and offers key insights for executives, space professionals and scholars alike.
