During the greater part of our history, the Moon was quite unreachable. It did not seem very big and far away but rather small. For the Greeks, the idea of walking on the Moon was certainly unthinkable, and as recently as the end of the 19th century many people doubted that humans would even be able to fly. Nevertheless, on July 20, 1969, the miracle happened. Since then many historic missions to explore the planets have been planned and executed, with the spacecraft and probes Mariner, Viking, Pioneer, Voyager, and Galileo leading the way. Thanks to human intelligence and effort we have succeeded in exploring many corners of our solar system. This book intends to show all this: the history of manned and unmanned voyages and the discoveries that were made. We will try, using simple and accessible language, to answer many questions, such as what rockets are, how they work, what shuttles exist, how astronauts live in space, and which robot probes are visiting other planets looking for signs of life.
