Cours de techniques et technologies des véhicules spatiaux, volume 3 is the third installment of a comprehensive course developed by the French space agency CNES. Published in December 1998 by Éditions Cépaduès, the volume spans 751 pages and covers advanced topics in spacecraft design, propulsion, materials, and mission systems. Intended for engineering students and professionals, the text combines theoretical foundations with practical applications drawn from decades of French spaceflight experience. The book includes detailed diagrams, tables, reference data, and illustrations that support the study of launch vehicles, orbital mechanics, onboard subsystems, and related support systems. As part of a three‑volume set, it provides a systematic progression from basic principles to specialized technologies used in contemporary space missions. The work remains a valuable reference for those involved in aerospace education and industry.
