This edited volume introduces the reader to the role of space in military and defense strategy, and outlines some of the major foreign and domestic actors in the space arena, as well as constraints of law and treaties on activities in space. It also addresses science and technology as they relate to space policy. The book addresses three main questions: How does the realm of space fit into strategic thinking about national security? How does policy regarding space develop and what considerations, both in the United States and abroad, figure prominently in calculations about space policy? How do different states/nations/actors regard the role of space in their national security calculations and how do these policies impact each other? This book fills a niche in the space policy field, providing insights into space and strategy from international experts from the military, academic and scientific communities. A unique feature of the book is the chapter on science and technology, which utilizes the latest information available concerning space utilization and exploration.

It is not yet 60 years since the first artificial satellite was placed into Earth orbit. In just over a half century, mankind has gone from no presence in outer space to a condition of high dependence on orbiting satellites. These sensors, receivers, transmitters, and other such devices, as well as the satellites that carry them, are components of complex space systems that include terrestrial elements, electronic links between and among components, organizations to provide the management, care and feeding, and launch systems that put satellites into orbit. In many instances, these space systems connect with and otherwise interact with terrestrial systems; for example, a very long list of Earth-based systems cannot function properly without information from the Global Positioning System (GPS). Space systems are fundamental to the information business, and the modern world is an information-driven one. In addition to navigation (and associated timing), space systems provide communications and imagery and other Earth-sensing functions. Among these systems are many that support military, intelligence, and other national security functions of the United States and many other nations. Some of these are unique government, national security systems; however, functions to support national security are also provided by commercial and civil-government space systems. 
The importance of space systems to the United States and its allies and potential adversaries raises major policy issues. National Security Space Defense and Protection reviews the range of options available to address threats to space systems, in terms of deterring hostile actions, defeating hostile actions, and surviving hostile actions, and assesses potential strategies and plans to counter such threats. This report recommends architectures, capabilities, and courses of action to address such threats and actions to address affordability, technology risk, and other potential barriers or limiting factors in implementing such courses of action.

The past five decades have witnessed often fierce international rivalry in space, but also surprising military restraint. Now, with an increasing number of countries capable of harming U.S. space assets, experts and officials have renewed a long-standing debate over the best route to space security. Some argue that space defenses will be needed to protect critical military and civilian satellites. Others argue that space should be a "sanctuary" from deployed weapons and military conflict, particularly given the worsening threat posed by orbital space debris. Moltz puts this debate into historical context by explaining the main trends in military space developments since Sputnik, their underlying causes, and the factors that are likely to influence their future course. This new edition provides analysis of the Obama administration's space policy and the rise of new actors, including China, India, and Iran. His conclusion offers a unique perspective on the mutual risks militaries face in space and the need for all countries to commit to interdependent, environmentally focused space security.

In Defense of Japan provides the first complete, up-to-date, English-language account of the history, politics, and policy of Japan's strategic space development. The dual-use nature of space technologies, meaning that they cut across both market and military applications, has had two important consequences for Japan. First, Japan has developed space technologies for the market in its civilian space program that have yet to be commercially competitive. Second, faced with rising geopolitical uncertainties and in the interest of their own economics, the makers of such technologies have been critical players in the shift from the market to the military in Japan's space capabilities and policy. This book shows how the sum total of market-to-military moves across space launch vehicles, satellites and spacecraft, and emerging related technologies, already mark Japan as an advanced military space power.

This book, Space Capstone Publication Spacepower: Doctrine for Space Forces, is capstone doctrine for the United States Space Force and represents our Service's first articulation of an independent theory of spacepower. This publication answers why spacepower is vital for our Nation, how military spacepower is employed, who military space forces are, and what military space forces value. In short, this capstone document is the foundation of our professional body of knowledge as we forge an independent military Service committed to space operations. Like all doctrine, the SCP remains subject to the policies and strategies that govern its employment. Military spacepower has deterrent and coercive capacities - it provides independent options for National and Joint leadership but achieves its greatest potential when integrated with other forms of military power. As we grow spacepower theory and doctrine, we must do so in a way that fosters greater integration with the Air Force, Army, Navy, Marine Corps, and Coast Guard. It is only by achieving true integration and interdependence that we can hope to unlock spacepower's full potential.

The proliferation of counterspace weapons across the globe often calls into question what can be done to best protect satellites from attack. This analysis from the CSIS Aerospace Security Project addresses different methods and technologies that can be used by the United States government, and others, to deter adversaries from attack. A wide range of active and passive defenses are available to protect space systems and the ground infrastructure they depend upon from different types of threats. This report captures a range of active and passive defenses that are theoretically possible and discusses the advantages and limitations of each. A group of technical space and national security experts supported the analysis by working through several plausible scenarios that explore a range of defenses that may be needed, concepts for employing different types of defenses, and how defensive actions in space may be perceived by others. These scenarios and the findings that resulted from subsequent conversations with experts are reported in the penultimate chapter of the report. Finally, the CSIS Aerospace Security Project team offers conclusions drawn from the analysis, actionable recommendations for policymakers, and additional research topics to be explored in future work.
