Collateral Damage to Satellites from An EMP Attack

In an age where global conflicts and technological advancements converge, the vulnerability of our space infrastructure to hostile actions is a critical concern that demands our immediate attention. From the intricate networks of GPS satellites guiding our precision munitions to the watchful eyes of intelligence-gathering platforms monitoring global hotspots, our reliance on space-based assets has become an undeniable reality. This 2010 publication by the Defense Threat Reduction Agency provides an unparalleled insight into the potential consequences of a high-altitude nuclear detonation on our critical space infrastructure. By unraveling the complex interplay of nuclear weapon effects and the dynamics of the space environment, it offers a stark and timely warning about the potential for catastrophic disruption. This book is not merely an academic exercise; it's a call to action, urging readers to confront the very real threats to our technological lifeline and to advocate for the robust protection of the space-based assets that underpin our modern world. This document presents an exhaustive study on the potential collateral damage to satellites from high-altitude nuclear detonations, a scenario of particular concern in the context of electromagnetic pulse (EMP) attacks. It provides a detailed overview of satellite populations, their orbits, and their strategic importance to the United States, both economically and militarily. Drawing upon lessons from atmospheric nuclear tests conducted in the late 1950s and early 1960s, the report highlights the potential for long-lived trapped energetic electrons, injected into Earth's magnetic fields by such detonations, to cause significant damage and premature failure of satellites. The document delves into the physical principles behind natural and nuclear weapon-enhanced space environments, focusing on trapped radiation like the Van Allen belts. It meticulously examines the effects of various types of natural and nuclear radiation on satellite electronic components, surface materials, and systems. The authors note, in particular, that previous studies may have underestimated the damaging effects of weapon-induced ultraviolet radiation on surface materials. To provide a comprehensive assessment, the report postulates twenty-one trial nuclear events with varying yields and locations as credible terrestrial EMP attacks or other nuclear threats. These events are then analyzed for their impact on representative low-Earth orbit (LEO) satellites, the GPS constellation, and a generic GEO satellite.The study concludes that LEO satellites are at substantial risk of exceeding their total dose limits for trapped radiation, especially if standard natural space hardening criteria are applied.However, the authors believe the likelihood of an individual satellite being close enough to a detonation to be directly threatened by prompt radiation effects is relatively low. This annotated edition illustrates the capabilities of the AI Lab for Book-Lovers to add context and ease-of-use to manuscripts. It includes several types of abstracts, building from simplest to more complex: TLDR (one word), ELI5, TLDR (vanilla), Scientific Style, and Action Items; essays to increase viewpoint diversity, such as Grounds for Dissent, Red Team Critique, and MAGA Perspective; and Notable Passages and Nutshell Summaries for each page.
