The Dept. of Defense¿s (DoD) operational dependence on space has placed new and increasing demands on current space systems to meet commanders¿ needs. DoD¿s Operationally Responsive Space (ORS) concept is designed to more rapidly satisfy commanders¿ needs for information and intelligence during ongoing operations. Given the potential for ORS to change how DoD acquires and fields space capabilities to support the warfighter, this report discusses to what extent DoD: (1) is developing ORS to support warfighter requirements; and (2) has a plan that integrates ORS into existing DoD and intelligence community processes and architecture. Includes recommendations. Charts and tables.
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.
As space develops as a potential war fighting domain, so does the need to have ethical scrutiny. Since the 1960s there have been core space treaties that together with national laws, provide a clear framework for both military and civilian space activities, yet ethical questions still exist around space warfare. Is it appropriate to respond kinetically on earth to a threat in space? Does just war theory apply in space and does the remoteness of space lower or raise the threshold for armed conflicts? Will the creation of new space forces start a space arms race? New combat environments also create a number of new challenges, including whether future war in space will be conducted by robots or space marines, and how the dual-use nature of satellites will impact on their permissibility as targets in any future conflict. As technologies become more widespread, space may be threatened by the likes of non-state groups and rogue states, leading to a need to inhibit their movement in space. In space, differences are magnified; resources are especially scarce, risks are multiplied, and specialized medical care is a world away. The physical and psychological distance between combatants in modern warfare applies also to space and the impacts of remote warfare need to be considered including the potential for moral injury and psychological trauma. With greater military power comes greater responsibility and this responsibility is carried out at the end of a chain of decisions and technologies. This book's relevancy will not be lost on students at service academies and staff colleges in preparing them for the task of emphasizing ethical responsibility in space to those whom they will lead in the future.
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.
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.
