This book offers a comprehensive and interdisciplinary exploration of the complex relationship between innovation, law, and security in the context of dual use technologies in space. As space activities expand rapidly, technologies developed for civilian purposes increasingly carry potential military or strategic applications, creating both opportunities and significant governance challenges. This volume examines these dynamics, providing a holistic understanding of the risks and benefits associated with dual use in space exploration and utilization. At its core, the book brings together perspectives from legal scholarship, engineering, international relations, and ethics to unpack the multifaceted nature of dual use technologies. It traces the evolution of international space law and regulatory frameworks, while also addressing technological advancements such as dual use satellites and innovations for space debris mitigation. In parallel, it explores the geopolitical implications of these technologies, highlighting how they influence global power structures, cooperation, and competition in outer space. The volume also engages with critical ethical questions surrounding dual use applications, including issues of responsibility, transparency, and the societal impact of emerging space technologies. Through a combination of case studies, historical analysis, and forward-looking insights, it provides a nuanced perspective on how innovation in space can be governed responsibly. By bridging disciplinary boundaries, this book aims to support informed decision-making and foster dialogue among policymakers, legal practitioners, engineers, and academics. It ultimately contributes to the development of robust frameworks for managing dual use technologies, ensuring that space innovation advances in a manner that is secure, ethical, and aligned with global interests.
