' ... may well become a standard textbook, for the pioneers of our first home beyond Earth.' Arthur C. Clarke, CBE, Colombo, Sri Lanka ' The book provides a very concise and pleasing summary of what is known and what is needed for the further development of life support systems.' Spaceflight, January 1995 ' A book which should be on the desk of every scientist and engineer working on regenerative life support systems.' Dr Donald Henninger, NASA-Johnson Space Center ' ... remarkable book not only covers life support technology ... , but also serves as a primer on principles of ecology and the nature of the space environment. It serves both as a reference for professionals and as an introductory text for those new to the field.' Dr Wendell Mendell, NASA-Johnson Space Center ' I recommend it to all the future aerospace engineers and to the confirmed space engineers who want to be informed about the specific field of space engineering.'
