Book Description
The Secure World Foundation developed the Handbook for New Actors in Space, which is intended to provide nations, established satellite operators, start-up companies, universities, and other space actors with a broad overview of the fundamental principles, laws, norms, and best practices for peaceful, safe, and responsible activities in space.

Book Description
A famous result of Christodoulou and Klainerman is the global nonlinear stability of Minkowski spacetime. In this book, Bieri and Zipser provide two extensions to this result. In the first part, Bieri solves the Cauchy problem for the Einstein vacuum equations with more general, asymptotically flat initial data, and describes precisely the asymptotic behavior. In particular, she assumes less decay in the power of $r$ and one less derivative than in the Christodoulou-Klainerman result. She proves that in this case, too, the initial data, being globally close to the trivial data, yields a solution which is a complete spacetime, tending to the Minkowski spacetime at infinity along any geodesic. In contrast to the original situation, certain estimates in this proof are borderline in view of decay, indicating that the conditions in the main theorem on the decay at infinity on the initial data are sharp. In the second part, Zipser proves the existence of smooth, global solutions to the Einstein-Maxwell equations. A nontrivial solution of these equations is a curved spacetime with an electromagnetic field. To prove the existence of solutions to the Einstein-Maxwell equations, Zipser follows the argument and methodology introduced by Christodoulou and Klainerman. To generalize the original results, she needs to contend with the additional curvature terms that arise due to the presence of the electromagnetic field $F$; in her case the Ricci curvature of the spacetime is not identically zero but rather represented by a quadratic in the components of $F$. In particular the Ricci curvature is a constant multiple of the stress-energy tensor for $F$. Furthermore, the traceless part of the Riemann curvature tensor no longer satisfies the homogeneous Bianchi equations but rather inhomogeneous equations including components of the spacetime Ricci curvature. Therefore, the second part of this book focuses primarily on the derivation of estimates for the new terms that arise due to the presence of the electromagnetic field.

Book Description
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.

Book Description
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.

Book Description
Over recent decades International Relations scholars have investigated norm dynamics processes at some length, with the ‘norm entrepreneur’ concept having become a common reference point in the literature. The focus on norm entrepreneurs has, however, resulted in a bias towards investigating the agents and processes of successful normative change. This book challenges this inherent bias by explicitly focusing on those who resist normative change - norm ‘antipreneurs’. The utility of the norm antipreneur concept is explored through a series of case studies encompassing a range of issue areas and contributed by a mix of well-known and emergent scholars of norm dynamics. In examining the complexity of norm resistance, particular attention is paid to the nature and intent of the actors involved in norm-contestation, the sites and processes of resistance, the strategies and tactics antipreneurs deploy to defend the values and interests they perceive to be threatened by the entrepreneurs, and whether it is the entrepreneurs or the antipreneurs who enjoy greater inherent advantages. This text will therefore be of interest to scholars and students of International Relations, International Law, Political Science, Sociology and History.
