"Next Generation CubeSats and SmallSats - Enabling Technologies, Missions, and Markets," ELSEVIER Editors: Francesco Branz, Chantal Cappelletti, Antonio J. Ricco, John Hines, 2023 Paperback ISBN: 9780128245415, eBook ISBN: 9780128245422 August 24, 2023 Next Generation of CubeSats and SmallSats: Enabling Technologies, Missions, and Markets provides a comprehensive understanding of the small and medium sized satellite approach and its potentialities and limitations. The book analyzes promising applications (e.g., constellations and distributed systems, small science platforms that overachieve relative to their development time and cost) as paradigm-shifting solutions for space exploitation, with an analysis of market statistics and trends and a prediction of where the technologies, and consequently, the field is heading in the next decade. The book also provides a thorough analysis of CubeSat potentialities and applications, and addresses unique technical approaches and systems strategies.
Throughout key sections (introduction and background, technology details, systems, applications, and future prospects), the book provides basic design tools scaled to the small satellite problem, assesses the technological state-of-the-art, and describes the most recent advancements with a look to the near future. This new book is for aerospace engineering professionals, advanced students, and designers seeking a broad view of the CubeSat world with a brief historical background, strategies, applications, mission scenarios, new challenges and upcoming advances.

Janson,2023 June 23, 2023 DOI: 10.1117/3.2618157 PDF ISBN: 9781510649347, Print ISBN: 9781510649330 This work assembles chapters from contributors across our planet to document technologies, applications, missions, licensing requirements, and lessons learned by individuals and organizations that have participated in the nanosatellite revolution. This book is not intended as a "how to" or as a university reference to design, build, and fly nanosatellites but as a deeper-level reference on what has and hasn't worked in previous nanosatellite programs. Many chapters act as a historical reference for particular programs.
