Clarion Foreword Reviews The author does a good job of simplifying complex calculus-derived orbital mechanics into simple concepts. He often does this by placing more technical data inside blue ""boxes"" interspersed throughout. There is a broad understanding of society's role in space exploration, with funding always being the central issue. But Sierra candidly reveals how the American military-industrial complex has been so completely interwoven with our space program, and how reams of huge multinational company proposals and contractor bidding have kept the cost extremely high. In addition, the author expertly addresses thought-provoking topics such as whether rocket engines are a thing of the past as well as possible futures in space exploration. U.S. Review of Books Sierra's phenomenally researched and lavishly illustrated book captures the excitement of that halcyon period, spanning everything from the Apollo missions and the Challenger space shuttle disaster to the International Space Station.
