The Complete Book of Spaceflight - From Apollo 1 to Zero Gravity - David Darling - Pdf






It is astonishing to think that there are people alive today from the time when man first flew in an engine powered, heavier-than-air plane. In the past century, we have learned not only to fly, but to fly to the Moon, to Mars, and to the very outskirts of the Solar System. Look up at the right time and place on a clear night and you can see the International Space Station glide across the sky and know that not all of us are now confined to Earth: always there are a handful of us on the near edge of this new and final frontier of space.
Our first steps beyond our home planet have been hesitant and hazardous. There are some who say, “Why bother?” Why expend effort and money, and risk lives, when there are so many problems to be resolved back on this world? In the end, the answer is simple. We can point to the enormous value of Earth resources satellites in monitoring the environment, or to the benefits of spacecraft that help us communicate among continents or predict the weather or gaze with clear sight across the light-years. We can extol the virtues of mining the Moon or the asteroid belt, or learning about our origins in cometary dust, or the things that can be made or gleaned from a laboratory in zero-g. But these reasons are not at the core of why we go — why we must go — on a voyage that will ultimately take us to the stars. Our reason for spaceflight is just this: we are human, and to be human is to be inquisitive. At heart, we are explorers with a universe of billions of new worlds before us.
This book is intended as a companion to the human journey into space. Of course, it has many facts and figures — and acronyms! — as all books on this subject do. But beyond the technical details of rockets and orbits, it tries to capture something of the drama of the quest, the human thread — in a word, the culture of space exploration. I hope that many readers will use it to wander from reference to reference and so create their own unique paths through this most unique of adventures.
Enjoy the ride!
