Weapons in Space examines how the United States is forcing forward—in violation of international treaties—to militarize space. Based on excerpts from U.S. government documents, award-winning investigative journalist Karl Grossman outlines the U.S. military's space doctrine, its similarity with the original Stars Wars scheme of Ronald Reagan and Edward Teller, and the space-based lasers, hypervelocity guns, and particle beams it plans to deploy in its mission to "dominate" earth. Grossman shows the intimate link between the militarization and the nuclearization of space, and follows the flow of billions of U.S. tax dollars to the corporations that research and develop weapons for space. His book explains the Outer Space Treaty and gives a history of the Global Network Against Weapons and Nuclear power in Space: what it is doing, what it plans to do—and what the reader can do to challenge U.S. plans to turn the heavens into a war zone.

This overview aims to inform the public discussion of space-based weapons by examining their characteristics, potential attributes, limitations, legality, and utility. The authors do not argue for or against space weapons, nor do they estimate the potential costs and performance of specific programs, but instead sort through the realities and myths surrounding space weapons in order to ensure that debates and discussions are based on fact.

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.
