Book Description
PRINT FORMAT ONLY 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 mélange 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.

Practicing Oral History to Improve Public Policies and Programs
Author: Marella Hoffman
Publisher: Routledge
ISBN: 1351607146
Category : History
Languages : en
Pages : 155
Book Description
The use of contemporary oral history to improve public policies and programs is a growing, transdisciplinary practice. Indispensable for students and practitioners, Practicing Oral History to Improve Public Policies and Programs is the first book to define the practice, explain how policy-makers use it, show how it relates to other types of oral history, and provide guidance on the ethics and legalities involved. Packed with case studies from disciplines as diverse as medicine, agriculture, and race relations, as well as many examples from the author’s own work, this book provides an essential overview of the current state of the field within oral history for public policy and a complete methodology for the process of designing and implementing an oral history project. The comprehensive How To section demonstrates how to use the practice to advance the reader’s career, their chosen discipline and the public interest, whether their field is in oral history or in public policy. This book is an important resource for oral historians, fledgling or experienced, who are keen to find new applications and funding for their work, as well as for professionals in the public and not-for-profit sectors who want to learn to use oral history to improve their own policies and programs.
