This is a great book on NASA's Pioneer project (not only the well-known - though already half-forgotten - Pioneer 10 and 11 missions to Jupiter and Saturn, but the whole series, including the highly successful 1978 mission to Venus). Very well written and researched, by a very talented young author, who's definitely in love with his subject. As the foreword of astronomer James van Allen states correctly, this book is first of all `a tale of human achievement', i.e. the emphasis of this book is very much on the project as such and on the people that made it possible (and how they did it). Wolverton does pay substantial attention to technical issues and to the scientific results of the various missions, it's true, but I would have preferred him going into more detail on all these things, providing more data and explaining more of the scientific achievements. To my tastes, he spends too much time discussing `the human factor' and the adventure side of it. But then again, this is the book's explicit `mission'. It just wasn't exactly what I expected, although I enjoyed it very much (especially the story about the controversy around the famous plaque with the naked couple on it, and on the old DEC PDP 11-14 `mini-`computer that was still being used in 2000 to communicate with Pioneer 10). So, this book is highly recommended and a Must for space buffs. It's also a very beautiful book, solid and robust. It's a bit of a pity that the - not too many - photographs and pictures are all in black-and-white. You can look into the book (all of the pages, and with color pictures!!!) on the publisher's website.
