Download or read book How to Kill an Asteroid: The Real Science of Planetary Defense written by Robin George Andrews. This book was released on 2024-10-01. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Planetary Defense by : Nikola Schmidt

Download or read book Planetary Defense written by Nikola Schmidt. This book was released on 2018-12-26. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis The Asteroid Threat by : William E. Burrows

Download or read book The Asteroid Threat written by William E. Burrows. This book was released on 2014-06-10. Available in PDF, EPUB and Kindle. Book excerpt: Presents a realistic, workable plan for defusing a potentially lethal threat from a rogue asteroid or comet. The explosion of a large meteor over Chelyabinsk, Siberia, in February 2013 is just the latest reminder that planet Earth is vulnerable to damaging and potentially catastrophic collisions with space debris of various kinds. In this informative and forward-looking book, veteran aerospace writer William E. Burrows explains what we can do in the future to avoid far more serious impacts from "Near-Earth Objects" (NEOs), as they are called in the planetary defense community. The good news is that humanity is now equipped with the advanced technology necessary to devise a long-term strategy to protect the planet. Burrows outlines the following key features of an effective planetary defense strategy: * A powerful space surveillance system capable of spotting a serious threat from space at least twenty-five years in advance * A space craft "nudge" that would throw a collision-course asteroid off target long before it poses the threat of imminent impact * A weapons system to be used as a last-ditch method to blast an NEO should all else fail. The author notes the many benefits for world stability and increasing international cooperation resulting from a united worldwide effort to protect the planet. Combining realism with an optimistic can-do attitude, Burrows shows that humanity is capable of overcoming a potentially calamitous situation.

Book Synopsis Super Volcanoes: What They Reveal about Earth and the Worlds Beyond by : Robin George Andrews

Download or read book Super Volcanoes: What They Reveal about Earth and the Worlds Beyond written by Robin George Andrews. This book was released on 2021-11-02. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Asteroid Apocalypse written by Rajeev Raghuram. This book was released on 2021-09-15. Available in PDF, EPUB and Kindle. Book excerpt: We all know what happened to the dinosaurs. Unable to do anything but observe, they watched as an asteroid hurled itself into Earth’s atmosphere and experienced the ramifications of the asteroid’s impact on the planet. Factors such as mass, velocity, type, and trajectory resulted in the extinction of seventy percent of life on Earth. Millions of years later, are we prepared for our battle against this same opponent? The Asteroid Apocalypse is an educational, nonfiction account of the asteroid threat to life on Earth. Detailing the latest science and technologies, The Asteroid Apocalypse guides readers through simulations and space missions that study the asteroid threat. Author Rajeev Raghuram provides readers with the historical context and accessible data to create a holistic understanding of the many potential threats Near-Earth Objects (NEOs) and Potentially Hazardous Objects (PHOs) pose to Earth, as well as how scientists and astronomers around the world prepare to respond to these possible threats. Young readers and aspiring space engineers, astronomers, and scientists everywhere will enjoy this introduction into the world of space rocks swirling around our planet and how we can work to ensure a fate different to that of the dinosaurs.
