Rock Fractures And Fluid Flow: Contemporary Understanding and Applications

by Committee on Fracture Characterization Fluid Flow

Scientific understanding of fluid flow in rock fractures--a process underlying contemporary earth science problems from the search for petroleum to the controversy over nuclear waste storage--has grown significantly in the past 20 years. This volume presents a comprehensive report on the state of the field, with an interdisciplinary viewpoint, case studies of fracture sites, illustrations, conclusions, and research recommendations.The book addresses these questions: How can fractures that are significant hydraulic conductors be identified, located, and characterized? How do flow and transport occur in fracture systems? How can changes in fracture systems be predicted and controlled?Among other topics, the committee provides a geomechanical understanding of fracture formation, reviews methods for detecting subsurface fractures, and looks at the use of hydraulic and tracer tests to investigate fluid flow. The volume examines the state of conceptual and mathematical modeling, and it provides a useful framework for understanding the complexity of fracture changes that occur during fluid pumping and other engineering practices.With a practical and multidisciplinary outlook, this volume will be welcomed by geologists, petroleum geologists, geoengineers, geophysicists, hydrologists, researchers, educators and students in these fields, and public officials involved in geological projects.

The Rock From Mars

by Kathy Sawyer

In this riveting book, acclaimed journalist Kathy Sawyer reveals the deepest mysteries of space and some of the most disturbing truths on Earth. The Rock from Mars is the story of how two planets and the spheres of politics and science all collided at the end of the twentieth century. It began sixteen million years ago. An asteroid crashing into Mars sent fragments flying into space and, eons later, one was pulled by the Earth’s gravity onto an icy wilderness near the southern pole. There, in 1984, a...

Rock Legends

by Paul Murdin

This book relates the history ofasteroid discoveries and christenings, from those of the early pioneeringgiants of Hersehel and Piazzi to modern-day amateurs. Moving from history andanecdotal information to science, the book's structure is provided by the namesof the asteroids, including one named after the author. Free from a need to conform toscientific naming conventions, the names evidence hero-worship, sycophancy,avarice, vanity, whimsy, erudition and wit, revealing the human side ofastronomers, especially where controversy has followed the christening. Murdindraws from extensive historical records to explore the debate over these names. Each age reveals its own biases and preferences in the naming process. Originally regarded as "vermin ofthe skies," asteroids are minor planets, rocky scraps left over from theformation of the larger planets, or broken fragments of worlds that havecollided. Their scientific classification as "minor" planets makes them seemunimportant, but over the past decades asteroids have been acknowledged to bekey players in the Solar System. This view of their starring role even alters thetrajectories of spacecraft: NASA's policy for new space missions en route tothe outer planets is that they must divert to study passing asteroids wheneverpossible. This book provides for readers a complete tour of the fascinatingworld of asteroids.

Rock | Water | Life: Ecology and Humanities for a Decolonial South Africa

by Lesley Green

In Rock | Water | Life Lesley Green examines the interwoven realities of inequality, racism, colonialism, and environmental destruction in South Africa, calling for environmental research and governance to transition to an ecopolitical approach that could address South Africa's history of racial oppression and environmental exploitation. Green analyzes conflicting accounts of nature in environmental sciences that claim neutrality amid ongoing struggles for land restitution and environmental justice. Offering in-depth studies of environmental conflict in contemporary South Africa, Green addresses the history of contested water access in Cape Town; struggles over natural gas fracking in the Karoo; debates about decolonizing science; the potential for a politics of soil in the call for land restitution; urban baboon management; and the consequences of sending sewage to urban oceans.

The Rocket and the Reich: Peenemunde and the Coming of the Ballistic Missile Era

by Michael J. Neufeld

WINNER OF THE DEXTER PRIZE OF THE SOCIETY FOR THE HISTORY OF TECHNOLOGY Launched by the Third Reich in late 1944, the first ballistic missile, the V-2, fell on London, Paris, and Antwerp after covering nearly two hundred miles in five minutes. It was a stunning achievement, one that heralded a new age of ballistic missiles and space launch vehicles. Michael J. Neufeld gives the first comprehensive and accurate account of the story behind one of the greatest engineering feats of World War II. At a time when rockets were minor battlefield weapons, Germany ushered in a new form of warfare that would bequeath a long legacy of terror to the Cold War, as well as the means to go into space. Both the US and USSR's rocket programs had their origins in the Nazi state.

Rocket Dreams: How the Space Age Shaped Our Vision of the World

by Marina Benjamin

In 1958, mankind's centuries-long flirtation with space flight became a torrid love affair. For a decade, tens of millions of people were enraptured -- first, by the U.S.-Soviet race to the moon, and finally, as America outstripped its rival, by Project Apollo alone. It is now more than three decades since the last man walked on the moon...more time than between the first moonwalk and the beginning of World War II. Apollo did not, as had been promised by a generation of visionaries, herald the beginning of the Space Age, but its end. Or did it? Project Apollo, like a cannonball, reached its apogee and returned to earth, but the trajectory of that return was complex. America's atmosphere -- its economic, scientific, and cultural atmosphere -- made for a very complicated reentry that produced many solutions to the trajectory problem. Rocket Dreams is about those solutions...about the places where the space program landed. In Rocket Dreams, an extraordinarily talented young writer named Marina Benjamin will take you on a journey to those landing sites. A visit with retired astronauts at a celebrity autograph show is a starting point down the divergent paths taken by the pioneers, including Edgar Mitchell, founder of the "church" of Noëtic Sciences. Roswell, New Mexico is a landing site of a different order, the "magnetic north" of UFO belief in the United States -- a belief that began its most dramatic growth precisely at the time that the path of the space program began its descent. In the vernacular, the third law of motion states that what goes up, must come down. Thus the tremendous motive force that energized the space program didn't just vanish; it was conserved and transformed, making bestsellers out of fantasy literature, spawning Gaia, and giving symbolism to the environmental movement. Everything from the pop cultural boom in ufology to the worldwide Search for Extra-Terrestrial Intelligence (SETI) feeds on the energy given off by America's leap toward space. Rocket Dreams is an eloquent tour of this Apollo-scarred landscape. It is also an introduction to some of the most fascinating characters imaginable: Some long dead, like the crackpot visionary Alfred Lawson, who saw in space flight a new stage of human evolution ("Alti-Man"), or Robert Goddard, the father of rocketry, whose workshop in Roswell stands only half a mile from shops selling posters of alien visitors. Others are very much alive -- like Stewart Brand, creator of the Whole Earth Catalog and partner with Gerard O'Neill in the drive to build free-floating space colonies, and SETI astronomer Seth Shostak, who has spent decades listening to the skies, hoping for the first contact with another intelligent species. Perceptive, original, and wonderfully written, informed by history, science, and an acute knowledge of popular culture, Rocket Dreams is a brilliant book by a remarkable talent.

Rocket Girl

by George D. Morgan

AN UNSUNG HEROINE OF THE SPACE AGE--HER STORY FINALLY TOLD. This is the extraordinary true story of America's first female rocket scientist. Told by her son, it describes Mary Sherman Morgan's crucial contribution to launching America's first satellite and the author's labyrinthine journey to uncover his mother's lost legacy--one buried deep under a lifetime of secrets political, technological, and personal. In 1938, a young German rocket enthusiast named Wernher von Braun had dreams of building a rocket that could fly him to the moon. In Ray, North Dakota, a young farm girl named Mary Sherman was attending high school. In an age when girls rarely dreamed of a career in science, Mary wanted to be a chemist. A decade later the dreams of these two disparate individuals would coalesce in ways neither could have imagined. World War II and the Cold War space race with the Russians changed the fates of both von Braun and Mary Sherman Morgan. When von Braun and other top engineers could not find a solution to the repeated failures that plagued the nascent US rocket program, North American Aviation, where Sherman Morgan then worked, was given the challenge. Recognizing her talent for chemistry, company management turned the assignment over to young Mary. In the end, America succeeded in launching rockets into space, but only because of the joint efforts of the brilliant farm girl from North Dakota and the famous German scientist. While von Braun went on to become a high-profile figure in NASA's manned space flight, Mary Sherman Morgan and her contributions fell into obscurity--until now. From the Trade Paperback edition.

Rocket Man: Robert H. Goddard and the Birth of the Space Age

by David A. Clary

This is the definitive biography of Robert H. Goddard (1882-1945) who was the father of rocketry and space flight, launching the world's first liquid-fuel rockets and the first powered vehicles to break the sound barrier.

Rocket Man: Robert H. Goddard and the Birth of the Space Age

by David A. Clary

More famous in his day than Einstein or Edison, the troubled, solitary genius Robert H. Goddard (1882-1945) was the American father of rocketry and space flight, launching the world's first liquid-fuel rockets and the first powered vehicles to break the sound barrier. Supported by Charles Lindbergh and Harry Guggenheim, through fiery, often explosive, experiments at Roswell, New Mexico, he invented the methods that carried men to the moon. Today, no rocket or jet plane can fly without using his inventions. Yet he is the "forgotten man" of the space age. His own government ignored his rocketry until the Germans demonstrated its principles in the V-2 missiles of World War II. The American government usurped his 214 patents, while suppressing his contributions in the name of national security, until it was forced to pay one million dollars for patent infringement. Goddard became famous again, monuments and medals raining upon his memory. But his renewed fame soon faded, and Goddard's pivotal role in launching the Space Age has been largely forgotten.

Rocket Men: The Daring Odyssey of Apollo 8 and the Astronauts Who Made Man's First Journey to the Moon

by Robert Kurson

<p>By August 1968, the American space program was in danger of failing in its two most important objectives: to land a man on the Moon by President Kennedy’s end-of-decade deadline, and to triumph over the Soviets in space. With its back against the wall, NASA made an almost unimaginable leap: It would scrap its usual methodical approach and risk everything on a sudden launch, sending the first men in history to the Moon—in just four months. And it would all happen at Christmas. <p>In a year of historic violence and discord—the Tet Offensive, the assassinations of Martin Luther King, Jr., and Robert Kennedy, the riots at the Democratic National Convention in Chicago—the Apollo 8 mission would be the boldest, riskiest test of America’s greatness under pressure. In this gripping insider account, Robert Kurson puts the focus on the three astronauts and their families: the commander, Frank Borman, a conflicted man on his final mission; idealistic Jim Lovell, who’d dreamed since boyhood of riding a rocket to the Moon; and Bill Anders, a young nuclear engineer and hotshot fighter pilot making his first space flight. <p>Drawn from hundreds of hours of one-on-one interviews with the astronauts, their loved ones, NASA personnel, and myriad experts, and filled with vivid and unforgettable detail, <i>Rocket Men</i> is the definitive account of one of America’s finest hours. In this real-life thriller, Kurson reveals the epic dangers involved, and the singular bravery it took, for mankind to leave Earth for the first time—and arrive at a new world.</p>
