Book Description
NOTE: NO FURTHER DISCOUNT FOR THIS PRINT PRODUCT- OVERSTOCK SALE-- Significantly reduced list price This new book from the NASA History Series tackles an interesting duo of biological problems that will be familiar to anybody who has seen photos of Apollo astronauts quarantined after their return to Earth.Namely, how do we avoid contaminating celestial bodies with Earthly germs when we send spacecraft to study these bodies, and how do we avoid spreading foreign biological matter from space when our robotic and human spacefarers return to Earth?Biological matter from an external system could potentially cause an unchecked epidemic either on Earth or in space so strict precautions are necessary. Each time a space vehicle visits another world it runs the risk of forever changing that extraterrestrial environment. We are surrounded on Earth by a melange of different microorganisms, and if some of these hitchhike onboard a space mission, they could contaminate and start colonies on a different planet. Such an occurrence would irrevocably alter the nature of that world, compromise all future scientific exploration of the body, and possibly damage any extant life on it.By inadvertently carrying exotic organisms back to Earth on our spacecraft, we also risk the release of biohazardous materials into our own ecosystem. Such concerns were recognized by scientists even before the 1957 launch of Sputnik. This book presents the history of planetary protection by tracing the responses to the above concerns on NASA s missions to the Moon, Mars, Venus, Jupiter, Saturn, and many smaller bodies of our solar system. The book relates the extensive efforts put forth by NASA to plan operations and prepare space vehicles that return exemplary science without contaminating the biospheres of other worlds or our own. To protect irreplaceable environments, NASA has committed to conducting space exploration in a manner that is protective of the bodies visited, as well as of our own planet."

Book Description
“[An] ambitious and... successful attempt to reset our relationship with the field of public health. With a judicious blend of candor, hopefulness and pragmatism, [Rivers] calls out its mistakes, reminds us of its historic accomplishments and emphasizes the need for the discipline to adjust its strategies if its full promise is to be realized.”—Wall Street Journal "A master class in how we can pinpoint and prevent health crises before they spiral out of control."—Scott Gottlieb, MD, author of Uncontrolled Spread A fascinating window into the secret life of epidemiology, weaving together stories of triumph and tragedy, with a boots-on-the-ground perspective on how we can avert the next public health crisis There are few visible markers of the accomplishments of public health. When epidemiologists do their jobs, nothing happens. An outbreak does not grow into an epidemic. A child does not go hungry. A would-be smoker never lights up. In this fascinating window into the secret life of public health, Caitlin Rivers weaves together stories of triumph and tragedy to show that by making sure things don't happen, she and legions of scientists, practitioners, and policymakers change the course of history. We have many of the tools and experiences needed to prevent the next crisis, but as past experiences teach us, the unexpected is always around the corner. We cannot afford complacency, as countless challenges remain, including constantly emerging pathogens, the rapid growth of biotechnology, and the inconsistent cycles of funding for public health programs. Progress can be slow, but the unsung heroes in epidemiology remain focused on their missions. Crisis Averted tells their stories—from the eradication of smallpox in the twentieth century to a battle against mosquito-borne diseases in the Florida Keys to the international safeguards implemented against extraterrestrial germs. By taking a candid look at how we solve problems in public health, Caitlin Rivers illuminates the role of epidemiology in all our lives and lays out the case for what can be accomplished given sufficient vision, leadership, and resources. Crisis Averted is an inspiring and galvanizing call for us to work together towards a healthier, more resilient future.

Book Description
Protecting Earth's environment and other solar system bodies from harmful contamination has been an important principle throughout the history of space exploration. For decades, the scientific, political, and economic conditions of space exploration converged in ways that contributed to effective development and implementation of planetary protection policies at national and international levels. However, the future of space exploration faces serious challenges to the development and implementation of planetary protection policy. The most disruptive changes are associated with (1) sample return from, and human missions to, Mars; and (2) missions to those bodies in the outer solar system possessing water oceans beneath their icy surfaces. Review and Assessment of Planetary Protection Policy Development Processes addresses the implications of changes in the complexion of solar system exploration as they apply to the process of developing planetary protection policy. Specifically, this report examines the history of planetary protection policy, assesses the current policy development process, and recommends actions to improve the policy development process in the future.

Book Description
Mars is a small world with a big reputation. This mysterious, singular planet—with volcanoes that dwarf Mount Everest, a canyon system that would stretch fully across the United States, and curious landscapes that perhaps once harbored water—has fascinated us for centuries. In the most up-to-date account available of the elusive Red Planet, Stephen James O’Meara follows our longstanding love affair with this unique celestial body, from the musings of humanity’s first stargazers to the imaginings of science-fiction writers, radio broadcasters, and filmmakers, to the latest images and discoveries from the Curiosity rover. The book also reviews plans for piloted missions to Mars—and what it will take for those missions to succeed.

Book Description
The search for life in the universe, once the stuff of science fiction, is now a robust worldwide research program with a well-defined roadmap probing both scientific and societal issues. This volume examines the humanistic aspects of astrobiology, systematically discussing the approaches, critical issues, and implications of discovering life beyond Earth. What do the concepts of life and intelligence, culture and civilization, technology and communication mean in a cosmic context? What are the theological and philosophical implications if we find life - and if we do not? Steven J. Dick argues that given recent scientific findings, the discovery of life in some form beyond Earth is likely and so we need to study the possible impacts of such a discovery and formulate policies to deal with them. The remarkable and often surprising results are presented here in a form accessible to disciplines across the sciences, social sciences, and humanities.

Book Description
The search for life in the Universe, once the domain of science fiction, is now a robust research program with a well-defined roadmap, from studying the extremes of life on Earth to exploring the possible niches for life in the Solar System and discovering thousands of planets far beyond it. In addition to constituting a major scientific endeavor, astrobiology is one of the most popular topics in astronomy, and is of growing interest to a broad community of thinkers from across the academic spectrum. In this volume, distinguished philosophers, theologians, anthropologists, historians and scientists discuss the big questions about how the discovery of extraterrestrial life, whether intelligent or microbial, would impact society. Their remarkable and often surprising findings challenge our foundational concepts of what the discovery of alien life may hold for humankind. Written in easily accessible language, this thought-provoking collection engages a wide audience of readers from all backgrounds.

Book Description
These interviews capture refections from top decision-makers as the space agency was completing its first 50 years. Based on oral histories, the book offers insights from those responsible for moving NASA through a deep transition - from the end of the Space Shuttle Program, the centerpiece of human spaceflight for three decades, to the goals of the new policy known as the Vision for Space Exploration.
