"More than forty chapters detail our current astronomical, compositional, geological, and geophysical knowledge of asteroids, as well as their unique physical processes and interrelationships with comets and meteorites"--Provided by publisher.
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.
One of the top scientists in the field of asteroid hunting explains how, for the first time, humanity could have the knowledge to prevent a devastating asteroid impact. --
This book shows how the discovery of the asteroids Ceres, Pallas Athena, Juno, and Vesta coincided with the shift of a woman. The creating, supporting, nurturing aspect held by the goddess Ceres, the universal mother, brings us to how we feel nurtured and how we function with our roles of mother-child. She embodies the principle of unconditional love. Pallas Athena is our Warrior Goddess, a woman in a man's world, carrying the principle of creative intelligence. Vesta, our goddess of Focus and Commitment, is our High Priestess. Juno, the Queen of Heaven and Divine Consort, is our capacity for meaningful relationships. Understanding the themes that each goddess holds enriches our understanding of that function and expression in our lives.
Grounded in historical studies of asteroids from the nineteenth century, Asteroids is a fully up-to-date view of these remarkable objects. Without resorting to any technical diagrams or mathematics, Clifford J. Cunningham shows that asteroids are not just rocks in space, but key to understanding the life and death on Earth of both animals and humans. From space missions to the asteroids’ starring role in literature and film, Cunningham precisely and entertainingly looks at the place asteroids have in our solar system and how they affect our daily lives.
"An asteroid is hurtling to Earth which could destroy everything on the planet. Scientists like Josh's mum are doing everything they can to stop it. But now they've run out of options. Internet rumours are rife and looters have taken to the streets. For Josh and his friends, Dave and Zack, it looks like their lives are over before they've begun. Because the asteroid is closer than ever, and the Earth is running out of time..."--
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 a year 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.
With the bulk of asteroids floating in space between the orbits of Mars and Jupiter, astronomers puzzle over where these rocks came from. Are they the remnants of a planet? Excess not used in the formation of the Solar System? Nothing more than random bits of debris? The location of the belt makes for a quasi-barrier separating the inner from the outer planets. Perhaps asteroids were meant to discourage human space exploration. NASA has sent missions to explore the asteroid belt and the rocks themselves, and those missions have yielded some interesting observations on the composition of the asteroids but no definitive answer as to their origin. Earth-based tools such as telescopes and satellites also contribute to asteroid research but cannot plumb the depths behind these varied chunks of flotsam. Presented in this book is a list of carefully chosen abstracts and citations of relevant literature about asteroids and the research into them. Prior to this listing, though, comes an overview of the nature of the asteroids and what we know now about them and what we hope to discover in the future. lifeless but mysterious rocks inhabiting the solar system. To conclude, easy access is provided through author, title, and subject indexes.
