This study was conducted under the auspices of Commission III （Space Technology & System Development） of the International Academy of Astronautics (IAA）， which benefited from review and comments by numerous members of the Academy， as well as members of the Commission. There were 12 participants in the study with many countries represented， such as China，France， India， Italy， Japan， Netherlands， Russia and the USA.The study could not have been completed to this level of detail without the timely and invaluable efforts of a diverse collection of experts from around the world who not only contributed their time and knowledge， but also provided material as well as their technical expertise to this study. These experts include members of the study group， the chapter authors to whom significant recognition should go， and especially the editors of the study (all names are provided in the Appendix）. The diverse contributors included individuals (as well as former staff now retired） from space agencies， commercial firms，universities and non-profit organizations.Thanks are also given to the members of the International Academy of Astronautics review committees who provided highly useful comments on the final draft of this study report.
