'The biggest change from previous editions is the inclusion of spreadsheets for nearly every calculation … All in all, this book does a good job at what it sets out to do. The formulas and algorithms are presented clearly and with an appropriate level of detail, and the spreadsheets supplement the text by showing an additional way to perform the computations without having to resort to a scientific calculator or writing your own programs.' Michael Coren, AstroMart.com
'This is a book replete with mathematical calculations but the opening pages to the various sections contain material of interest to the lay reader.' Spaceflight
