Book Description
From Habitability to Life on Mars explores the current state of knowledge and questions on the past habitability of Mars and the role that rapid environmental changes may have played in the ability of prebiotic chemistry to transition to life. It investigates the role that such changes may have played in the preservation of biosignatures in the geological record and what this means for exploration strategies. Throughout the book, the authors show how the investigation of terrestrial analogs to early Martian habitats under various climates and environmental extremes provide critical clues to understand where, what and how to search for biosignatures on Mars. The authors present an introduction to the newest developments and state-of-the-art remote and in situ detection strategies and technologies that are being currently developed to support the upcoming ExoMars and Mars 2020 missions. They show how the current orbital and ground exploration is guiding the selection for future landing sites. Finally, the book concludes by discussing the critical question of the implications and ethics of finding life on Mars. - Edited by the lead on a NASA project that searches for habitability and life on Mars leading to the Mars 2020 mission - Presents the evidence, questions and answers we have today (including a summary of the current state of knowledge in advance of the ESA ExoMars and NASA Mars 2020 missions) - Includes contributions from authors directly involved in past, current and upcoming Mars missions - Provides key information as to how Mars rovers, such as ExoMars and Mars 2020, will address the search for life on Mars with their instrumentation

Book Description
The search for life on Mars—and the moral issues confronting us as we prepare to send humans there Does life exist on Mars? The question has captivated humans for centuries, but today it has taken on new urgency. As space agencies gear up to send the first manned missions to the Red Planet, we have a responsibility to think deeply about what kinds of life may already dwell there—and whether we have the right to invite ourselves in. Telling the complete story of our ongoing quest to answer one of the most tantalizing questions in astronomy, David Weintraub grapples with the profound moral and ethical questions confronting us as we prepare to introduce an unpredictable new life form—ourselves—into the Martian biosphere. Now with an afterword that discusses the most recent discoveries, Life on Mars explains what we need to know before we go.

Book Description
“Sarah Stewart Johnson interweaves her own coming-of-age story as a planetary scientist with a vivid history of the exploration of Mars in this celebration of human curiosity, passion, and perseverance.”—Alan Lightman, author of Einstein’s Dreams WINNER OF THE PHI BETA KAPPA AWARD FOR SCIENCE • NAMED ONE OF THE BEST BOOKS OF THE YEAR BY The New York Times Book Review • Times (UK) • Library Journal “Lovely . . . Johnson’s prose swirls with lyrical wonder, as varied and multihued as the apricot deserts, butterscotch skies and blue sunsets of Mars.”—Anthony Doerr, The New York Times Book Review Mars was once similar to Earth, but today there are no rivers, no lakes, no oceans. Coated in red dust, the terrain is bewilderingly empty. And yet multiple spacecraft are circling Mars, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium, and Mare Sirenum—on the brink, perhaps, of a staggering find, one that would inspire humankind as much as any discovery in the history of modern science. In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own. Johnson’s fascination with Mars began as a child in Kentucky, turning over rocks with her father and looking at planets in the night sky. She now conducts fieldwork in some of Earth’s most hostile environments, such as the Dry Valleys of Antarctica and the salt flats of Western Australia, developing methods for detecting life on other worlds. Here, with poetic precision, she interlaces her own personal journey—as a female scientist and a mother—with tales of other seekers, from Percival Lowell, who was convinced that a utopian society existed on Mars, to Audouin Dollfus, who tried to carry out astronomical observations from a stratospheric balloon. In the process, she shows how the story of Mars is also a story about Earth: This other world has been our mirror, our foil, a telltale reflection of our own anxieties and yearnings. Empathetic and evocative, The Sirens of Mars offers an unlikely natural history of a place where no human has ever set foot, while providing a vivid portrait of our quest to defy our isolation in the cosmos.

Book Description
Winner of the 2012 Pulitzer Prize * Poet Laureate of the United States * * A New York Times Notable Book of 2011 and New York Times Book Review Editors' Choice * * A New Yorker, Library Journal and Publishers Weekly Best Book of the Year * New poetry by the award-winning poet Tracy K. Smith, whose "lyric brilliance and political impulses never falter" (Publishers Weekly, starred review) You lie there kicking like a baby, waiting for God himself To lift you past the rungs of your crib. What Would your life say if it could talk? —from "No Fly Zone" With allusions to David Bowie and interplanetary travel, Life on Mars imagines a soundtrack for the universe to accompany the discoveries, failures, and oddities of human existence. In these brilliant new poems, Tracy K. Smith envisions a sci-fi future sucked clean of any real dangers, contemplates the dark matter that keeps people both close and distant, and revisits the kitschy concepts like "love" and "illness" now relegated to the Museum of Obsolescence. These poems reveal the realities of life lived here, on the ground, where a daughter is imprisoned in the basement by her own father, where celebrities and pop stars walk among us, and where the poet herself loses her father, one of the engineers who worked on the Hubble Space Telescope. With this remarkable third collection, Smith establishes herself among the best poets of her generation.

Book Description
The field of planetary biology and chemical evolution draws together experts in astronomy, paleobiology, biochemistry, and space science who work together to understand the evolution of living systems. This field has made exciting discoveries that shed light on how organic compounds came together to form self-replicating molecules-the origin of life. This volume updates that progress and offers recommendations on research programs-including an ambitious effort centered on Mars-to advance the field over the next 10 to 15 years. The book presents a wide range of data and research results on these and other issues: The biogenic elements and their interaction in the interstellar clouds and in solar nebulae. Early planetary environments and the conditions that lead to the origin of life. The evolution of cellular and multicellular life. The search for life outside the solar system. This volume will become required reading for anyone involved in the search for life's beginnings-including exobiologists, geoscientists, planetary scientists, and U.S. space and science policymakers.

Book Description
Nearly five billion years ago, Earth and Mars were born together as planetary siblings orbiting a young, emerging Sun. Yet today, one planet is water rich and life bearing, while the other is seemingly cold, dry, and forbidding. Earth and Mars is a fusion of art and science, a blend of images and essays celebrating the successful creation of our life-sustaining planet and the beauty and mystery of Mars. Through images of terrestrial landscapes and photographs selected from recent NASA and European Space Agency missions to Mars, Earth and Mars reveals the profound beauty resulting from the action of volcanism, wind, and water. The accompanying text provides a context for appreciating the role of these elemental forces in shaping the surfaces of each planet, as well as the divergent evolutionary paths that led to an Earth that is teeming with life, and Mars that is seemingly lifeless. Earth and Mars inspires reflection on the extraordinarily delicate balance of forces that has resulted in our good fortune: to be alive and sentient on a bountiful blue world.
