Spacecraft Systems Engineering Textbook

A spacecraft can satisfy every subsystem specification and still fail as an integrated mission. The cause is often found between disciplines: a requirement without a clear owner, an interface based on different assumptions, a budget that hides uncertainty, a model tied to the wrong configuration, or a verification activity that cannot prove the intended claim. Spacecraft Systems Engineering provides a practical, life-cycle framework for preventing those gaps. >Inside, readers will learn how to: - Frame mission objectives, system boundaries, stakeholders, modes, and success measures.- Write measurable requirements and maintain allocation, traceability, baselines, and change control.- Develop functional, logical, physical, and model-based architecture views.- Conduct trade studies using constraints, uncertainty, sensitivity, and documented decision logic.- Manage mass, power, energy, thermal, data, pointing, communications, reliability, and propellant budgets.- Plan interface control, verification, qualification, acceptance, integration, anomaly resolution, technical reviews, ground operations, and end-of-mission activities.Worked examples define variables, preserve units, state assumptions, calculate results, and interpret what those results mean for margin, risk, architecture, and readiness. Practice problems strengthen both numerical ability and systems-level judgment. Six practical appendices provide starting templates for traceability records, budget worksheets, trade studies, failure analysis, verification documentation, interface control, technical planning, and review preparation. The treatment keeps technical integrity at the center. It shows how to state uncertainty, control configurations, connect evidence to requirements, document decision authority, and recognize when a result is sufficient, conditional, or blocked. Readers gain a structured way to review complex interactions without losing the mission purpose behind them. The book is written for senior undergraduate and graduate students, early-career engineers, subsystem specialists moving into integration roles, systems engineers, technical leads, project managers, operators, and instructors. It offers general engineering methods and educational models rather than mission-specific authority or flight-ready values. >Trademarked Disclaimer All organization names, program names, mission names, standards designations, software names, product names, and trademarks referenced in this publication are the property of their respective owners.
