Dr. Homer Newell, a deputy director of NASA, has written in Express To The Stars what might well be one of the groundling's guides to the space age. Certainly though there's absolutely nothing here to cause a stir at Cape Canaveral or even a Ph. D's lab, the book is still responsibly informed, easy to read, easy to understand and stocked with enough ready-to-use material to delight the budding scientist. Dr. Newell explores the history of rockets, from V-2 to single to multi-stage, propulsion and propellants, construction from liquid to solid, cutoff and bluff circuits, telemetring, portable and mobile ranges, count downs and full-scale analyses of test sequences. There's the X-15 high altitude flight of Major White, missiles ballistic, guided and aerodynamic, celestial mechanics and the first satellite. Project Mercury and Russia's globe orbital Vostok, rockets 'sounding' the atmosphere, research for peace and experiments for defense, the Soviet's still secret Geophysical space ship and just about everything else needed to bring one up to date, or at least get the picture in proper perspective. The drawings, diagrams, figures and tables are all well integrated with the text, besides which a much-needed glossary of key terms is enclosed. For all those who haven't been reading their newspapers too closely during the last few years, this should be an entertainment, an education and a good buy.
