Riassunto

An insider's look at the science of near-Earth comets and asteroids

Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system's origins, and someday could even serve as stepping-stones for space exploration. In this book, Donald Yeomans introduces readers to the science of near-Earth objects—its history, applications, and ongoing quest to find near-Earth objects before they find us.

In its course around the sun, the Earth passes through a veritable shooting gallery of millions of nearby comets and asteroids. One such asteroid is thought to have plunged into our planet sixty-five million years ago, triggering a global catastrophe that killed off the dinosaurs. Yeomans provides an up-to-date and accessible guide for understanding the threats posed by near-Earth objects, and also explains how early collisions with them delivered the ingredients that made life on Earth possible. He shows how later impacts spurred evolution, allowing only the most adaptable species to thrive—in fact, we humans may owe our very existence to objects that struck our planet.

Yeomans takes readers behind the scenes of today's efforts to find, track, and study near-Earth objects. He shows how the same comets and asteroids most likely to collide with us could also be mined for precious natural resources like water and oxygen, and used as watering holes and fueling stations for expeditions to Mars and the outermost reaches of our solar system.

Dalla quarta di copertina

"This is a wonderful and timely book, not to mention a great read! Asteroids are indeed wondrous objects, and it is simply a matter of time before we find one with our address on it. Yeomans' unparalleled expertise, storytelling skills, and wry sense of humor are a savory delight. Enjoy!"--Rusty Schweickart, Apollo 9 astronaut

"The nearby asteroids are Earth's closest neighbors and key stepping stones for our expansion into space. Yet these rogue space rocks can also threaten our planet. Noted scientist Donald Yeomans is one of NASA's 'men in black,' keeping an eye out for wayward asteroids. He clearly explains what we know about these celestial denizens--and what discoveries will help us avoid a cosmic catastrophe."--Tom Jones, veteran astronaut, author of Sky Walking

"Many people consider near-Earth objects to be important only because they pose a threat to Earth, but there are many other reasons for studying them. This book explains why. I know of no better introduction to the subject."--Michael F. A'Hearn, University of Maryland

"This is an excellent and interesting book. I found it enjoyable and informative, and I strongly recommend it to anyone seeking a better understanding of near-Earth objects and the solar system in general."--Daniel J. Scheeres, University of Colorado at Boulder

"This is a fine book. Yeomans treats all the important aspects of his topic, including finding near-Earth objects and calculating their orbits, the broader issues of solar system origins and early evolution, the threat of impacts by near-Earth objects of various sizes, and approaches to preventing impacts from occurring. The scholarship is at a high level."--Clark R. Chapman, Southwest Research Institute
