Definition and Status of Space Security

Abstract

Space security has gained increasing importance over the past decade as space becomes part of our everyday life. Yet, space security is not universally defined. The shift of paradigm and transformation of the space domain through new ways of utilizing space and recent technological advances such as mega-constellations, 5G, Internet of Things, artificial intelligence, and advanced materials have resulted both in major challenges and new opportunities. Over the years, space security has evolved. Since the signature of the Outer Space Treaty in 1967, space security has become a complex, broader, and multilayered concept. The topic dominates space law and space policy agendas at the United Nations General Assembly Committees and the Committee on the Peaceful Uses of Outer Space along with its subsidiary bodies. In this context, this chapter aims to effectively capture the multifaceted concept of space security and provide an overview of its current status.
