Rocket Science. Two words which are synonymous with complexity. Two words which for many people signify the zenith of human genius. A phrase which has entered the English lexicon to describe the toughest discipline in human endeavour. Author Alfred Zaehringer has a unique perspective on both the phrase and the discipline. In this book, his first about space in nearly forty years, Alfred Zaehringer uses his lifetime of experience to take the mystery out of the phrase he coined. Beginning with a short history of the birth of rocketry he moves into an explanation of the physics that makes it possible to use rockets to fly in space. Leaving no stone unturned he moves on to the politics and economics of space-flight before providing a detailed cross-section of man's different uses of the reaction rocket to fly into the heavens. Finally he looks at the proposals for future methods of space transportation and looks at the many promising new technologies which may offer cheaper access to space.
