When Biospheres Collide

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."

As Cassie Conley, NASA's Planetary Protection Officer, has said, "The public can be proud of the way that NASA has responded to planetary protection concerns, with its efforts to act responsibly, communicate openly, and address effectively the potential for contamination." Humans have a powerful urge to explore the unknown, but 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.

This book examines the question of what we mean when we talk about life, revealing new insights into what life is, what it does, and why it matters. Jenell Johnson studies arguments on behalf of life—not just of the human or animal variety, but all life. She considers, for example, the Standing Rock Sioux tribe’s fight for water, deep ecologists’ Earth First! activism, the Voluntary Human Extinction Movement, and astrophysicists’ positions on Martian microbes. What she reveals is that this advocacy—vital advocacy—expands our view of what counts as life and shows us what it would mean for the moral standing of human life to be extended to life itself. Including short interviews with celebrated ecological writer Dorion Sagan, former NASA Planetary Protection Officer Catharine Conley, and leading figure in Indigenous and environmental studies Kyle Whyte, Every Living Thing provides a capacious view of life in the natural world. This book is a must-read for anyone interested in biodiversity, bioethics, and the environment.

Wall Street Journal Bestseller New York Times bestselling author Dan Heath explores how to prevent problems before they happen, drawing on insights from hundreds of interviews with unconventional problem solvers. So often in life, we get stuck in a cycle of response. We put out fires. We deal with emergencies. We stay downstream, handling one problem after another, but we never make our way upstream to fix the systems that caused the problems. Cops chase robbers, doctors treat patients with chronic illnesses, and call-center reps address customer complaints. But many crimes, chronic illnesses, and customer complaints are preventable. So why do our efforts skew so heavily toward reaction rather than prevention? Upstream probes the psychological forces that push us downstream—including “problem blindness,” which can leave us oblivious to serious problems in our midst. And Heath introduces us to the thinkers who have overcome these obstacles and scored massive victories by switching to an upstream mindset. One online travel website prevented twenty million customer service calls every year by making some simple tweaks to its booking system. A major urban school district cut its dropout rate in half after it figured out that it could predict which students would drop out—as early as the ninth grade. A European nation almost eliminated teenage alcohol and drug abuse by deliberately changing the nation’s culture. And one EMS system accelerated the emergency-response time of its ambulances by using data to predict where 911 calls would emerge—and forward-deploying its ambulances to stand by in those areas. Upstream delivers practical solutions for preventing problems rather than reacting to them. How many problems in our lives and in society are we tolerating simply because we’ve forgotten that we can fix them?

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.
