First, men travelled in their own imagination, driven by their intelligence, which was fuelled by their myths. Who has never heard the myth of Icarus, the first man to fly? In fact, since the beginning of history, it has been the desire of man to reach the heavens, the dominion and abode of the gods, and this desire has given us beautiful stories. With this book I want to tell the story of astronautics, which according to the dictionary is science and its technology that deals with space flights, but I go further, because I see astronautics as the science that transforms dreams into reality. With this work I close with a flourish a project that I started more than 10 years ago: the collection "We and the Universe: astronomy", where I hoped to tell the world how wonderful the sky is, much more than only those little dots of light indicate that they are. I thank and reiterate my gratitude to everyone who is following my work, to everyone who helped me and supported me to get here. This is not my mother language, but I used the few I know about it to translate my book and show my ideas to you. I am a Brazilian writer, and I hope that you like this book, as I loved to write it!
