Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Asteroids written by Martin Elvis and published by Yale University Press. This book was released on 2021-06-08 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique, wide-ranging examination of asteroid exploration and our future in space Human travel into space is an enormously expensive and unforgiving endeavor. So why go? In this accessible and authoritative book, astrophysicist Martin Elvis argues that the answer is asteroid exploration, for the strong motives of love, fear, and greed. Elvis’s personal motivation is one of scientific love—asteroid investigations may teach us about the composition of the solar system and the origins of life. A more compelling reason may be fear—of a dinosaur killer–sized asteroid hitting our planet. Finally, Elvis maintains, we should consider greed: asteroids likely hold vast riches, such as large platinum deposits, and mining them could provide both a new industry and a funding source for bolder space exploration. Elvis explains how each motive can be satisfied, and how they help one another. From the origins of life, to “space billiards,” and space sports, Elvis looks at how asteroids may be used in the not-so-distant future.

Download or read book Super Volcanoes What They Reveal about Earth and the Worlds Beyond written by Robin George Andrews and published by W. W. Norton & Company. This book was released on 2021-11-02 with total page 265 pages. 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 Space at the Speed of Light written by Dr. Becky Smethurst and published by Ten Speed Press. This book was released on 2020-06-02 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the big bang to black holes, this fast-paced illustrated tour of time and space for the astro-curious unlocks the science of the stars to reveal fascinating theories, surprising discoveries, and ongoing mysteries in modern astronomy and astrophysics. Before the big bang, time, space, and matter didn't exist. In the 14 billion years since, scientists have pointed their telescopes upward, peering outward in space and backward in time, developing and refining theories to explain the weird and wonderful phenomena they observed. Through these observations, we now understand concepts like the size of the universe (still expanding), the distance to the next-nearest star from earth (Alpha Centauri, 26 trillion miles) and what drives the formation of elements (nuclear fusion), planets and galaxies (gravity), and black holes (gravitational collapse). But are these cosmological questions definitively answered or is there more to discover? Oxford University astrophysicist and popular YouTube personality Dr. Becky Smethurst presents everything you need to know about the universe in ten accessible and engagingly illustrated lessons. In Space at the Speed of Light: The History of 14 Billion Years for People Short on Time, she guides you through fundamental questions, both answered and unanswered, posed by space scientists. Why does gravity matter? How do we know the big bang happened? What is dark matter? Do aliens exist? Why is the sky dark at night? If you have ever looked up at night and wondered how it all works, you will find answers--and many more questions--in this pocket-sized tour of the universe!
Download or read book Breaking the Chains of Gravity written by Amy Shira Teitel and published by Bloomsbury Publishing. This book was released on 2015-10-22 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

It provides detailed derivations for attitude kinematics and dynamics and provides detailed description of the most widely used attitude parameterization, the quaternion. This title also provides a thorough treatise of attitude dynamics including Jacobian elliptical functions. It is the first known book to provide detailed derivations and explanations of state attitude determination and gives readers real-world examples from actual working spacecraft missions. The subject matter is chosen to fill the void of existing textbooks and treatises, especially in state and dynamics attitude determination. MATLAB code of all examples will be provided through an external website.
Download or read book Out There written by Michael Wall and published by Grand Central Publishing. This book was released on 2018-11-13 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the vein of Randall Munroe's What If? meets Brian Green's Elegant Universe, a senior writer from Space.com leads readers on a wild ride of exploration into the final frontier, investigating what's really "out there." We've all asked ourselves the question. It's impossible to look up at the stars and NOT think about it: Are we alone in the universe? Books, movies and television shows proliferate that attempt to answer this question and explore it. In Out There Space.com senior writer Dr. Michael Wall treats that question as merely the beginning, touching off a wild ride of exploration into the final frontier. He considers, for instance, the myriad of questions that would arise once we do discover life beyond Earth (an eventuality which, top NASA officials told Wall, is only drawing closer). What would the first aliens we meet look like? Would they be little green men or mere microbes? Would they be found on a planet in our own solar system or orbiting a star far, far away? Would they intend to harm us, and if so, how might they do it? And might they already have visited? Out There is arranged in a simple question-and-answer format. The answers are delivered in Dr. Wall's informal but informative style, which mixes in a healthy dose of humor and pop culture to make big ideas easier to swallow. Dr. Wall covers questions far beyond alien life, venturing into astronomy, physics, and the practical realities of what long-term life might be like for we mere humans in outer space, such as the idea of lunar colonies, and even economic implications. Dr. Wall also shares the insights of some of the leading lights in space exploration today, and shows how the next space age might be brighter than ever./DIV

Download or read book The Plague Year written by Lawrence Wright and published by Knopf. This book was released on 2021-06-08 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Pulitzer Prize–winning author of The Looming Tower, and the pandemic novel The End of October: an unprecedented, momentous account of Covid-19—its origins, its wide-ranging repercussions, and the ongoing global fight to contain it "A book of panoramic breadth ... managing to surprise us about even those episodes we … thought we knew well … [With] lively exchanges about spike proteins and nonpharmaceutical interventions and disease waves, Wright’s storytelling dexterity makes all this come alive.” —The New York Times Book Review From the fateful first moments of the outbreak in China to the storming of the U.S. Capitol to the extraordinary vaccine rollout, Lawrence Wright’s The Plague Year tells the story of Covid-19 in authoritative, galvanizing detail and with the full drama of events on both a global and intimate scale, illuminating the medical, economic, political, and social ramifications of the pandemic. Wright takes us inside the CDC, where a first round of faulty test kits lost America precious time . . . inside the halls of the White House, where Deputy National Security Adviser Matthew Pottinger’s early alarm about the virus was met with confounding and drastically costly skepticism . . . into a Covid ward in a Charlottesville hospital, with an idealistic young woman doctor from the town of Little Africa, South Carolina . . . into the precincts of prediction specialists at Goldman Sachs . . . into Broadway’s darkened theaters and Austin’s struggling music venues . . . inside the human body, diving deep into the science of how the virus and vaccines function—with an eye-opening detour into the history of vaccination and of the modern anti-vaccination movement. And in this full accounting, Wright makes clear that the medical professionals around the country who’ve risked their lives to fight the virus reveal and embody an America in all its vulnerability, courage, and potential. In turns steely-eyed, sympathetic, infuriated, unexpectedly comical, and always precise, Lawrence Wright is a formidable guide, slicing through the dense fog of misinformation to give us a 360-degree portrait of the catastrophe we thought we knew.
