Book Description
A gripping account of the “city-killer” asteroids that could threaten Earth and the race to build a planetary defense system. There are approximately 25,000 “city killer” asteroids in near-Earth orbit—and most are yet to be found. Small enough to evade detection, they are capable of large-scale destruction, and represent our greatest cosmic threat. But in September 2022, against all odds, NASA’s Double Asteroid Redirection Test (DART) mission deliberately crashed a spacecraft into a carefully selected city killer, altering the asteroid’s orbit and proving that we stand a chance against them. In How to Kill an Asteroid, award-winning science journalist Robin George Andrews—who was at DART mission control when it happened—reveals the development of the technology that made it possible, from spotting elusive asteroids and comets to figuring out their geologic defenses and orchestrating a deflection campaign. In a propulsive narrative that reads like a sci-fi thriller, Andrews tells the story of the planetary defense movement, and introduces the international team of scientists and engineers now working to protect Earth.

Book Description
An exhilarating, time-traveling journey to the solar system’s strangest and most awe-inspiring volcanoes. Volcanoes are capable of acts of pyrotechnical prowess verging on magic: they spout black magma more fluid than water, create shimmering cities of glass at the bottom of the ocean and frozen lakes of lava on the moon, and can even tip entire planets over. Between lava that melts and re-forms the landscape, and noxious volcanic gases that poison the atmosphere, volcanoes have threatened life on Earth countless times in our planet’s history. Yet despite their reputation for destruction, volcanoes are inseparable from the creation of our planet. A lively and utterly fascinating guide to these geologic wonders, Super Volcanoes revels in the incomparable power of volcanic eruptions past and present, Earthbound and otherwise—and recounts the daring and sometimes death-defying careers of the scientists who study them. Science journalist and volcanologist Robin George Andrews explores how these eruptions reveal secrets about the worlds to which they belong, describing the stunning ways in which volcanoes can sculpt the sea, land, and sky, and even influence the machinery that makes or breaks the existence of life. Walking us through the mechanics of some of the most infamous eruptions on Earth, Andrews outlines what we know about how volcanoes form, erupt, and evolve, as well as what scientists are still trying to puzzle out. How can we better predict when a deadly eruption will occur—and protect communities in the danger zone? Is Earth’s system of plate tectonics, unique in the solar system, the best way to forge a planet that supports life? And if life can survive and even thrive in Earth’s extreme volcanic environments—superhot, superacidic, and supersaline surroundings previously thought to be completely inhospitable—where else in the universe might we find it? Traveling from Hawai‘i, Yellowstone, Tanzania, and the ocean floor to the moon, Venus, and Mars, Andrews illuminates the cutting-edge discoveries and lingering scientific mysteries surrounding these phenomenal forces of nature.

Book Description
Planetary defense from near-Earth objects such as asteroids is a far more nuanced and challenging topic than it might seem. Each day, technology is making it easier to detect asteroid impact threats in advance, but at present, there is still no easy way to design and implement any form of global defense. This book examines how various asteroid deflection methods can change global political affairs. The authors believe that the final policy for potential Earth impacts should be based on practical engineering solutions and innovative architectural structures, while at the same time reflecting the most recent political science contributions in ethical security studies and security cosmopolitanism. Their focus is not limited to effective engineering solutions, but rather extends to how such proposals resonate in possible political structures of the future. Planetary defense cannot be achieved with technology alone; the chapters in this volume highlight the issues that arise when space science and technology intersect with political science. This complex interdisciplinary project not only demands global participation and collaboration, but also proposes the way we can achieve it. The authors explore various concepts of governance and their far-reaching implications for planetary defense and vice versa—how scientific progress in Solar System observations and asteroid collision engineering influence political science and put pressure on the international legal framework. The text is intentionally written for a diverse scholarly and diplomatic audience in a style accessible to non-specialists and practitioners and can be read by those across diverse disciplinary backgrounds.

Book Description
The incredible story of spaceflight before the establishment of NASA. NASA's history is a familiar story, one that typically peaks with Neil Armstrong taking his small step on the Moon in 1969. But America's space agency wasn't created in a vacuum. It was assembled from pre-existing parts, drawing together some of the best minds the non-Soviet world had to offer. In the 1930s, rockets were all the rage in Germany, the focus both of scientists hoping to fly into space and of the German armed forces, looking to circumvent the restrictions of the Treaty of Versailles. One of the key figures in this period was Wernher von Braun, an engineer who designed the rockets that became the devastating V-2. As the war came to its chaotic conclusion, von Braun escaped from the ruins of Nazi Germany, and was taken to America where he began developing missiles for the US Army. Meanwhile, the US Air Force was looking ahead to a time when men would fly in space, and test pilots like Neil Armstrong were flying cutting-edge, rocket-powered aircraft in the thin upper atmosphere. Breaking the Chains of Gravity tells the story of America's nascent space program, its scientific advances, its personalities and the rivalries it caused between the various arms of the US military. At this point getting a man in space became a national imperative, leading to the creation of the National Aeronautics and Space Administration, otherwise known as NASA.

Book Description
An archaeological exploration of the mysterious world of cave art through the ages Deep underground, some of humanity’s earliest artistic endeavors have lain untouched for millennia. The dark interiors of caves, wherever they may be found, seem to have had a powerful draw for ancient peoples, who littered the cave floors with objects they had made. Later, they adorned cave walls with sacred symbols and secret knowledge, from the very first abstract symbols and handprints to complex and vivid arrangements of animals and people. Often undisturbed for many tens of thousands of years, these were among the first visual symbols that humans shared with each other, though they were made so long ago that we have entirely forgotten their meaning. However, as archaeologist Bruno David reveals, caves decorated more recently may help us to unlock their secrets. David tells the story of this mysterious world of decorated caves, from the oldest known painting tools to the magnificent murals of the European Ice Age. Showcasing the most astounding discoveries made in more than 150 years of archaeological exploration, Cave Art explores the creative achievements of our remotest ancestors and what they tell us about the human past.

Book Description
How might the world as we know it end? In this illustrated guide, How Stuff Works author Marshall Brain explores myriad doomsday scenarios and the science behind them. What if the unimaginable happens? A nuclear bomb detonates over a major city, for example, or a deadly virus infects millions around the world. There are other disasters we don’t even have to imagine because they’ve already occurred, like violent hurricanes or cataclysmic tsunamis that have caused horrific loss of life and damage. In The Doomsday Book, Marshall Brain explains how everything finally ends—the decimation of nations and cities, of civilization, of humanity, of all life on Earth. Brain takes a deep dive into a wide range of doomsday narratives, including manmade events such as an electromagnetic pulse attack, a deadly pandemic, and nuclear warfare; devastating natural phenomena, such as an eruption from a super-volcano, the collapse of the Gulf Stream, or lethal solar flares; and science-fiction scenarios where robots take over or aliens invade. Each compelling chapter provides a detailed description of the situation, the science behind it, and ways to prevent or prepare for its occurrence. With fun graphics and eye-catching photographs at every turn, The Doomsday Book will be the last book you’ll ever have to read about the last days on Earth. Scenarios include: - Asteroid Strike: a massive asteroid could obliterate life—just as it might have killed the dinosaurs. - Gray Goo: self-replicating nanobots engulf the planet. - Grid Attack: an attack on our power grid shuts down the internet, affecting airports, banks, computers, food delivery, medical devices, and the entire economic system. - Gulf Stream collapse: the shutdown of this important ocean current causes temperatures to plummet. - Ocean acidification: if the oceans’ pH levels shift due to a rise in carbon dioxide, all marine life could die.

Book Description
The United States spends approximately $4 million each year searching for near-Earth objects (NEOs). The objective is to detect those that may collide with Earth. The majority of this funding supports the operation of several observatories that scan the sky searching for NEOs. This, however, is insufficient in detecting the majority of NEOs that may present a tangible threat to humanity. A significantly smaller amount of funding supports ways to protect the Earth from such a potential collision or "mitigation." In 2005, a Congressional mandate called for NASA to detect 90 percent of NEOs with diameters of 140 meters of greater by 2020. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies identifies the need for detection of objects as small as 30 to 50 meters as these can be highly destructive. The book explores four main types of mitigation including civil defense, "slow push" or "pull" methods, kinetic impactors and nuclear explosions. It also asserts that responding effectively to hazards posed by NEOs requires national and international cooperation. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies is a useful guide for scientists, astronomers, policy makers and engineers.

Book Description
In this history of extinction and existential risk, a Newsweek and Bloomberg popular science and investigative journalist examines our most dangerous mistakes -- and explores how we can protect and future-proof our civilization. End Times is a compelling work of skilled reportage that peels back the layers of complexity around the unthinkable -- and inevitable -- end of humankind. From asteroids and artificial intelligence to volcanic supereruption to nuclear war, veteran science reporter and TIME editor Bryan Walsh provides a stunning panoramic view of the most catastrophic threats to the human race. In End Times, Walsh examines threats that emerge from nature and those of our own making: asteroids, supervolcanoes, nuclear war, climate change, disease pandemics, biotechnology, artificial intelligence, and extraterrestrial intelligence. Walsh details the true probability of these world-ending catastrophes, the impact on our lives were they to happen, and the best strategies for saving ourselves, all pulled from his rigorous and deeply thoughtful reporting and research. Walsh goes into the room with the men and women whose job it is to imagine the unimaginable. He includes interviews with those on the front lines of prevention, actively working to head off existential threats in biotechnology labs and government hubs. Guided by Walsh's evocative, page-turning prose, we follow scientific stars like the asteroid hunters at NASA and the disease detectives on the trail of the next killer virus. Walsh explores the danger of apocalypse in all forms. In the end, it will be the depth of our knowledge, the height of our imagination, and our sheer will to survive that will decide the future.
