About this book:

*Orbital Debris Management* provides a comprehensive technical, legal, and economic framework for addressing the escalating crisis of space junk. The book establishes that the orbital environment is not a uniform void but a collection of distinct regimes—LEO, MEO, and GEO—each governed by different physical dynamics and requiring tailored mitigation strategies. It details the fundamental physics of orbital mechanics and atmospheric drag, which dictate how fragments from explosions and collisions evolve over time, potentially leading to the catastrophic "Kessler Syndrome" of self-sustaining debris cascades.

The text shifts from theoretical risk to operational practice, examining the vital roles of Space Situational Awareness (SSA) and Space Traffic Management (STM). It describes the global network of ground- and space-based sensors used to track objects, the importance of standardized data formats like CDMs and TLEs, and the mathematical modeling required for conjunction assessment and collision-probability calculations. The author emphasizes that as mega-constellations proliferate, traditional manual oversight must give way to automated, AI-driven coordination to handle the sheer volume of close-approach alerts and maneuver planning.

The book also evaluates engineering solutions and preventative design, such as "design for demise" to ensure satellites burn up upon reentry, and the passivation of spent rocket stages to prevent on-orbit explosions. It transitions into the maturing fields of Active Debris Removal (ADR) and on-orbit servicing, detailing concepts like robotic grapples, harpoons, and lasers. While these technologies offer a way to remediate existing hazards, the text acknowledges that their implementation is currently hindered by high costs, the lack of standardized interfaces, and complex legal questions regarding ownership and dual-use security concerns.

In its final chapters, the book argues that debris management is ultimately a governance and economic challenge. It reviews international treaties, national licensing regulations (such as those from the FCC), and voluntary guidelines like those from the IADC. The author proposes a global roadmap that utilizes insurance premiums, orbital bonds, and shared metrics to internalize the costs of debris creation. By aligning commercial incentives with long-term environmental stewardship, the book suggests that the orbital commons can be preserved as a sustainable resource for future scientific and commercial exploration.
