This new and beautifully illustrated account of Venus takes in the most recent research into this mysterious, inhospitable world. Looking at the history of our observations of the planet, from early astronomy to future space missions, it seeks to answer many of the questions that remain unanswered, such as why Venus and Earth, so similar in size and mass, evolved in such different directions, and how Venus acquired its dense carbon-dioxide atmosphere. Above all, it assesses whether life might have escaped from the oven-like temperatures at the surface and evolved to become perpetually airborne - in which case Venus may not be lifeless after all.

Near the end of the Apollo 15 mission, David Scott and fellow moonwalker James Irwin conducted a secret ceremony unsanctioned by NASA: they placed on the lunar soil a small tin figurine called The Fallen Astronaut, along with a plaque bearing a list of names. By telling the stories of those sixteen astronauts and cosmonauts who died in the quest to reach the moon between 1962 and 1972, this book enriches the saga of humankind's greatest scientific undertaking, Project Apollo, and conveys the human cost of the space race. Many people are aware of the first manned Apollo mission, in which Gus Grissom, Ed White, and Roger Chaffee lost their lives in a fire during a ground test, but few know of the other five fallen astronauts whose stories this book tells as well, including Ted Freeman and C.C. Williams, who died in the crashes of their T-38 jets; the "Gemini Twins," Charlie Bassett and Elliot See, killed when their jet slammed into the building where their Gemini capsule was undergoing final construction; and Ed Givens, whose fatal car crash has until now been obscured by rumors. Supported by extensive interviews and archival material, the extraordinary lives and accomplishments of these and other fallen astronauts-including eight Russian cosmonauts who lost their lives during training-unfold here in intimate and compelling detail. Their stories return us to a stirring time in the history of our nation and remind us of the cost of fulfilling our dreams. This revised edition includes expanded and revised biographies and additional photographs. Purchase the audio edition.

This is a book about rocket science: what it is and what it does. From the earliest fireworks to nuclear-powered spacecraft, all you would ever want or need to know about the subject is here, along with a straightforward explanation of how, why and when things work-or sometimes don't. We begin with the history and workings of early terrestrial rocketry before moving onto the main subject of the book: how we get things into space and, on occasion, back again. Entirely math-free, the chapters weave together innumerable anecdotes, real-world examples, and easy walk-throughs to help readers break down the complex physics behind some of humankind's most amazing feats. Neither a pure textbook nor a populist space travel tome, the book will educate, inform and above all entertain anyone intrigued by rocket science.

A tight-knit, high-powered group of scientists and engineers spent eight years building a satellite designed, in effect, to read the genome of the universe. Launched in 2001, the Wilkinson Microwave Anisotropy Probe (WMAP) reported its first results two years later with a set of brilliant observations that added focus, detail, and insight to our formerly fuzzy view of the cosmos.

For more than a year, the WMAP satellite hovered in the cold of deep space, a million miles from Earth, in an effort to determine whether the science of cosmology--the study of the origin and evolution of the universe--has been on the right track for the past two decades. What WMAP was looking for was a barely perceptible pattern of hot and cold spots in the faint whisper of microwave radiation left over from the Big Bang, the event that almost 14 billion years ago gave birth to all of space, time, matter, and energy.

The pattern encoded in those microwaves holds the answers to some of the great unanswered questions of cosmology: What is the universe made of? What is its geometry? How much of it consists of the mysterious dark matter and dark energy that continue to baffle astronomers? How fast is it expanding? And did it undergo a period of inflationary hyper-expansion at the very beginning? WMAP has now given definitive answers to these mysteries.

On February 11, 2003, the team of researchers went public with the results. Just some of their extraordinary findings: The universe is 13.7 billion years old. The first stars--turned on--when the universe was only 200 million years old, five times earlier than anyone had thought. It is now certain that a mysterious dark energy dominates the universe. Michael Lemonick, who had exclusive access to the researchers as WMAP gathered its data, here tells the full story of WMAP and its surprising revelations. This book is both a personal and a scientific tale of discovery. In its pages, readers will come to know the science of cosmology and the people who, seventy-five years after we first learned that the universe is expanding, deciphered some of its deepest mysteries in the patterns of its oldest light.

Willy Ley inspired young rocket scientists and would-be astronauts around the world to imagine a future of interplanetary travel long before space shuttles existed. This is the first biography of the science writer and rocketeer who predicted and boosted the rise of the Space Age. Born in Germany, Ley became involved in amateur rocketry until the field was taken over by the Nazis. He fled to America, where he forged a new life as a weapons expert and journalist during World War II and as a rocket researcher after the war. As America's foremost authority on rockets, missiles, and space travel, he authored books and scientific articles, while also regularly writing for science fiction pulp magazines and publishing what he termed romantic zoology--a blend of zoology, cryptozoology, history, and mythology. He even consulted for television's Tom Corbett, Space Cadet and the Disney program Man in Space, thrilling audiences with a romanticized view of what spaceflight would be like. Yet as astronauts took center stage and scientific intellectuals such as Wernher von Braun became influential during the space race, Ley lost his celebrity status. With an old-fashioned style of popular writing and eccentric perspectives influenced by romanticism and science fiction, he was ignored by younger historians. This book returns Willy Ley to his rightful place as the energizer of an era--a time when scientists and science popularizers mixed ranks and shared the spotlight so that our far-fetched, fantastic dreams could turn into the reality of tomorrow.

The solar system has always been a messy place in which gravity wreaks havoc. Moons form, asteroids and comets crash into planets, ice ages commence, and dinosaurs disappear. By describing the dramatic consequences of such disturbances, this authoritative and entertaining book reveals the fundamental interconnectedness of the solar system--and what it means for life on Earth.

After relating a brief history of the solar system, Alan Rubin describes how astronomers determined our location in the Milky Way. He provides succinct and up-to-date accounts of the energetic interactions among planetary bodies, the generation of the Earth's magnetic field, the effects of other solar-system objects on our climate, the moon's genesis, the heating of asteroids, and the origin of the mysterious tektites. Along the way, Rubin introduces us to the individual scientists--including the famous, the now obscure, and the newest generation of researchers--who have enhanced our understanding of the galactic neighborhood. He shows how scientific discoveries are made; he discusses the uncertainty that presides over the boundaries of knowledge as well as the occasional reluctance of scientists to change their minds even when confronted by compelling evidence. This fresh historical perspective reveals science as it is: an imperfect but self-correcting enterprise.

Journeying to the frontiers of knowledge, Rubin concludes with the exciting realm of astrobiology. He chronicles the history of the search for life on Mars and describes cutting-edge lines of astrobiological inquiry, including panspermia (the possible transfer of life from planet to planet), the likelihood of technologically advanced alien civilizations in our galaxy, and our probable responses to alien contact.

Authoritative and up-to-date but also entertaining and fluidly written, "Disturbing the Solar System" will appeal to any reader who has ever picked up a rock or gazed at the moon with a sense of wonder.

Orienting us with an insider's tour of our cosmic home, the Milky Way, William Waller and Paul Hodge then take us on a spectacular journey, inviting us to probe the exquisite structures and dynamics of the giant spiral and elliptical galaxies, to witness colliding and erupting galaxies, and to pay our respects to the most powerful galaxies of all-the quasars. A basic guide to the latest news from the cosmic frontier-about the black holes in the centers of galaxies, about the way in which some galaxies cannibalize each other, about the vast distances between galaxies, and about the remarkable new evidence regarding dark energy and the cosmic expansion-this book gives us a firm foundation for exploring the more speculative fringes of our current understanding. This is a heavily revised and completely updated version of Hodge's Galaxies, which won an Association of American Publishers PROSE Award for Best Science Book of the Year in 1986.
