The threat to the sky from satellite mega-constellations, why it matters, and what we can do about it From the foreword by Brian May: "Professor Lawrence, in this timely book, tackles an issue which is about to become highly contentious around the world... This book will hopefully spark enough discussion to put the brakes on this destruction of our dark skies." From Dava Sobel, author "Longitude" and "The Glass Universe": "At the beginning of this essential book, Andy Lawrence shares dark sky memories in which even a car breakdown on a deserted road turns magical and formative when the stars appear. Let there be dark." From Dave Eicher, editor-in-chief of Astronomy Magazine: “Professor Lawrence’s book ought to be required reading for every astronomer and astronomy enthusiast who values the starry sky and what might happen to it in future times.” From Mark McCaughrean, Senior Science Adviser, European Space Agency: "As commercial developers flood low Earth orbit with satellites to exploit the demand for more movie streaming, videoconferencing, low-latency gaming, and high-speed trading, what's the real cost? ." From Pippa Goldschmidt, author of The Falling Sky and The Need for Better Regulation of Outer Space: “An important book about an important subject. Professor Andy Lawrence explains how obliteration of our view of the heavens by the next generation of communications satellites is akin to destruction of the Earth’s natural habitats.” From John A. Murray, author or editor of 45 nature books, including Wild Africa, A Republic of Rivers, and The Islands and The Sea: "Simply put, this remarkable book should be in all libraries, public or private, that aspire to be complete on the subjects of science and technology. Working together, people around the planet, inspired by this eloquent and passionate book, can put an end to the madness and folly of "artificial constellations" "
