Available in PDF, EPUB and Kindle. Book excerpt: From Fossils to Astrobiology reviews developments in paleontology and geobiology that relate to the rapidly-developing field of Astrobiology, the study of life in the Universe. Many traditional areas of scientific study, including astronomy, chemistry and planetary science, contribute to Astrobiology, but the study of the record of life on planet Earth is critical in guiding investigations in the rest of the cosmos. In this varied book, expert scientists from 15 countries present peer-reviewed, stimulating reviews of paleontological and astrobiological studies. The overviews of established and emerging techniques for studying modern and ancient microorganisms on Earth and beyond, will be valuable guides to evaluating biosignatures which could be found in the extraterrestrial surface or subsurface within the Solar System and beyond. This volume also provides discussion on the controversial reports of "nanobacteria" in the Martian meteorite ALH84001. It is a unique volume among Astrobiology monographs in focusing on fossil evidence from the geological record and will be valuable to students and researchers alike.

Book Synopsis Lakes on Mars by : Nathalie A. Cabrol
Download or read book Lakes on Mars written by Nathalie A. Cabrol and published by Elsevier. This book was released on 2010-09-15 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: On Earth, lakes provide favorable environments for the development of life and its preservation as fossils. They are extremely sensitive to climate fluctuations and to conditions within their watersheds. As such, lakes are unique markers of the impact of environmental changes. Past and current missions have now demonstrated that water once flowed at the surface of Mars early in its history. Evidence of ancient ponding has been uncovered at scales ranging from a few kilometers to possibly that of the Arctic ocean. Whether life existed on Mars is still unknown; upcoming missions may find critical evidence to address this question in ancient lakebeds as clues about Mars' climate evolution and its habitability potential are still preserved in their sedimentary record. Lakes on Mars is the first review on this subject. It is written by leading planetary scientists who have dedicated their careers to searching and exploring the questions of water, lakes, and oceans on Mars through their involvement in planetary exploration, and the analysis of orbital and ground data beginning with Viking up to the most recent missions. In thirteen chapters, Lakes on Mars critically discusses new data and explores the role that water played in the evolution of the surface of Mars, the past hydrological provinces of the planet, the possibility of heated lake habitats through enhanced geothermal flux associated with volcanic activity and impact cratering. The book also explores alternate hypotheses to explain the geological record. Topographic, morphologic, stratigraphic, and mineralogic evidence are presented that suggest successions of ancient lake environments in Valles Marineris and Hellas. The existence of large lakes and/or small oceans in Elysium and the Northern Plains is supported both by the global distribution of deltaic deposits and by equipotential surfaces that may reflect their past margins. Whether those environments were conducive to life has yet to be demonstrated but from comparison with our planet, their sedimentary deposits may provide the best opportunity to find its record, if any. The final chapters explore the impact of climate variability on declining lake habitats in one of the closest terrestrial analogs to Mars at the Noachian/Hesperian transition, identify the geologic, morphologic and mineralogic signatures of ancient lakes to be searched for on Mars, and present the case for landing the Mars Science Laboratory mission in such an environment. - First review on the subject by worldwide leading authorities in the field - New studies with most recent data, new images, figures, and maps - Most recent results from research in terrestrial analogs
Book Synopsis An Astrobiology Strategy for the Exploration of Mars by : National Research Council
Download or read book An Astrobiology Strategy for the Exploration of Mars written by National Research Council and published by National Academies Press. This book was released on 2007-06-26 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three recent developments have greatly increased interest in the search for life on Mars. The first is new information about the Martian environment including evidence of a watery past and the possibility of atmospheric methane. The second is the possibility of microbial viability on Mars. Finally, the Vision for Space Exploration initiative included an explicit directive to search for the evidence of life on Mars. These scientific and political developments led NASA to request the NRC's assistance in formulating an up-to-date integrated astrobiology strategy for Mars exploration. Among other topics, this report presents a review of current knowledge about possible life on Mars; an astrobiological assessment of current Mars missions; a review of Mars-mission planetary protection; and findings and recommendations. The report notes that the greatest increase in understanding of Mars will come from the collection and return to Earth of a well-chosen suite of Martian surface materials.
Download or read book The Fossil written by Joshua T Calvert and published by . This book was released on 2021-03-04 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: A human fossil on Mars. An astronaut who lost her memory and a powerful organization that keeps a secret in Antarctica-one that will change the world forever. In 2018, Canadian archaeologist Ron Jackson makes a mind-boggling discovery in Antarctica-right before disappearing without a trace, leaving behind only his controversial theory that humans have lived on Earth far, far longer than we think they have. Decades later, in 2042, when Jackson's wife dies under mysterious circumstances, an unlikely pair of investigators, Agatha Devenworth and Pano Hofer, begin investigating whether her death might be connected to Jackson's disappearance. What exactly was it he found before he vanished? Why is the Human Foundation, a hyper-powerful business empire built on an endless series of game-changing inventions it has been rolling out, one after another, for over twenty years, trying to hide the truth from the two investigators? And what could it possibly have to do with the first manned mission to Mars, which ended in disaster leaving countless conspiracy theories in its wake?
Book Synopsis Ancient Aliens on Mars II by : Mike Bara
Download or read book Ancient Aliens on Mars II written by Mike Bara and published by SCB Distributors. This book was released on 2014-06-02 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Ancient Aliens on Mars II, New York Times bestselling author Mike Bara returns the reader to Mars to examine the enduring mysteries of the Red Planet. Building on the case made in Ancient Aliens on Mars and using data acquired from sophisticated new scientific instruments like the Mars Odyssey THEMIS infrared imager, Bara shows that the region of Cydonia overlays a vast underground city full of enormous structures and devices that may still be operating. He peels back the layers of mystery to show images of tunnel systems, temples and ruins, and exposes the sophisticated NASA conspiracy designed to hide them and discredit the researchers that discovered these exotic ruins. Bara also tackles the enigma of Mars’ hollowed out moon Phobos, and exposes evidence from over 30 years of observations that it is artificial. Long-held myths about Mars, including claims that it is protected by a sophisticated UFO defense system, are examined and illuminated. Data from the Mars rovers Spirit, Opportunity and Curiosity is examined; everything from fossilized plants to mechanical debris is exposed in images taken directly from NASA’s own archives. Finally, the author offers his take on the secret history of the Red Planet and what happened to the highly advanced civilization that once flourished there.
Book Synopsis The Rock From Mars by : Kathy Sawyer
Download or read book The Rock From Mars written by Kathy Sawyer and published by Random House. This book was released on 2006-02-14 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 geologist named Roberta Score spotted it, launching it on a roundabout path to fame and controversy. In its new home at NASA’s Johnson Space Center in Houston, the rock languished on a shelf for nine years, a victim of mistaken identity. Then, in 1993, the geochemist Donald “Duck” Mittlefehldt, unmasked the rock as a Martian meteorite. Before long, specialist Chris Romanek detected signs of once-living organisms on the meteorite. And the obscure rock became a rock star. But how did nine respected investigators come to make such startling claims about the rock that they triggered one of the most venomous scientific battles in modern memory? The narrative traces the steps that led to this risky move and follows the rippling impact on the scientists’ lives, the future of space exploration, the search for life on Mars, and the struggle to understand the origins of life on Earth. From the second the story broke in Science magazine in 1996, it spawned waves of excitement, envy, competitive zeal, and calculation. In academia, in government agencies, in laboratories around the world, and even in the Oval Office–where an inquisitive President Clinton had received the news in secret– players of all kinds plotted their next moves. Among them: David McKay, the dynamic geologist associated with the first moon landing, who labored to achieve at long last a second success; Bill Schopf of UCLA, a researcher determined to remain at the top of his field and the first to challenge McKay’s claims; Dan Goldin, the boss of NASA; and Dick Morris, the controversial presidential adviser who wanted to use the story for Clinton’s reelection and unfortunately made sure it ended up in the diary of a $200-an-hour call girl. Impeccably researched and thrillingly involving, Kathy Sawyer’s The Rock from Mars is an exemplary work of modern nonfiction, a vivid account of the all-too-human high-stakes drive to learn our true place in the cosmic scheme.
Book Synopsis The Sirens of Mars by : Sarah Stewart Johnson
Download or read book The Sirens of Mars written by Sarah Stewart Johnson and published by Crown. This book was released on 2020-07-07 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: “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 Synopsis There's Nothing to Do on Mars by : Chris Gall
Download or read book There's Nothing to Do on Mars written by Chris Gall and published by Little, Brown Books for Young Readers. This book was released on 2009-02-28 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Davey Martin's family moves to Mars, he discovers that there's nothing to do--at least until he and his robot dog Polaris learn to seize the spirit of adventure. It's not until they've zipped around the planet on his flying scooter--climbing Martian "trees," digging up "fossils," dancing in Martian rain dances--that they discover a treasure that finally piques Davey's interest--a source of water on the red planet! Chris Gall's new picture book plays on the themes (and ironies) of a complaint parents have heard from their children a thousand times: "There's nothing to do!" The book also offers a deeper lesson to our stationary, convenience-driven society: If you're creative and look carefully, you'll be amazed at what you find!
Book Synopsis Comodo_Draconis_martianus by : Michael D. Moore
Download or read book Comodo_Draconis_martianus written by Michael D. Moore and published by Outskirts Press. This book was released on 2018-12-21 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author has provided descriptions of each image along with a link that will take the reader directly to the raw image on the official government website where it can be seen. Many of the images contain the mummified and fossilized remains of creatures that once lived within Gale Crater on Mars. Curiosity's mission was to discover if conditions on Mars were ever favorable for the emergence of life. That mission was accomplished in the first quarter of 2013, when the rover drilled holes in the Martian bedrock at two locations, John Klein and Cumberland. In addition to drilling and analyzing soil, Curiosity inadvertently captured the remains of extinct life upon the surface and within outcrops. These images show that life follows the same patterns on Mars and Earth. They also indicate that as we move outward into the Universe the pattern for life will remain the same. A duck on Earth, a duck on Mars and a duck found within the farthest reaches of the Universe will look the same.
Download or read book Terraforming Mars written by Martin Beech and published by John Wiley & Sons. This book was released on 2021-12-09 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: TERRAFORMING MARS This book provides a thorough scientific review of how Mars might eventually be colonized, industrialized, and transformed into a world better suited to human habitation. The idea of terraforming Mars has, in recent times, become a topic of intense scientific interest and great public debate. Stimulated in part by the contemporary imperative to begin geoengineering Earth, as a means to combat global climate change, the terraforming of Mars will work to make its presently hostile environment more suitable to life—especially human life. Geoengineering and terraforming, at their core, have the same goal—that is to enhance (or revive) the ability of a specific environment to support human life, society, and industry. The chapters in this text, written by experts in their respective fields, are accordingly in resonance with the important, and ongoing discussions concerning the human stewardship of global climate systems. In this sense, the text is both timely and relevant and will cover issues relating to topics that will only grow in their relevance in future decades. The notion of terraforming Mars is not a new one, as such, and it has long played as the background narrative in many science fiction novels. This book, however, deals exclusively with what is physically possible, and what might conceivably be put into actual practice within the next several human generations. Audience Researchers in planetary science, astronomy, astrobiology, space engineering, architecture, ethics, as well as members of the space industry.

Book Synopsis The Cosmic Zoo by : Dirk Schulze-Makuch
Download or read book The Cosmic Zoo written by Dirk Schulze-Makuch and published by Springer. This book was released on 2017-11-18 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Are humans a galactic oddity, or will complex life with human abilities develop on planets with environments that remain habitable for long enough? In a clear, jargon-free style, two leading researchers in the burgeoning field of astrobiology critically examine the major evolutionary steps that led us from the distant origins of life to the technologically advanced species we are today. Are the key events that took life from simple cells to astronauts unique occurrences that would be unlikely to occur on other planets? By focusing on what life does - it's functional abilities - rather than specific biochemistry or anatomy, the authors provide plausible answers to this question. Systematically exploring the various pathways that led to the complex biosphere we experience on planet Earth, they show that most of the steps along that path are likely to occur on any world hosting life, with only two exceptions: One is the origin of life itself – if this is a highly improbable event, then we live in a rather “empty universe”. However, if this isn’t the case, we inevitably live in a universe containing a myriad of planets hosting complex as well as microbial life - a “cosmic zoo”. The other unknown is the rise of technologically advanced beings, as exemplified on Earth by humans. Only one technological species has emerged in the roughly 4 billion years life has existed on Earth, and we don’t know of any other technological species elsewhere. If technological intelligence is a rare, almost unique feature of Earth's history, then there can be no visitors to the cosmic zoo other than ourselves. Schulze-Makuch and Bains take the reader through the history of life on Earth, laying out a consistent and straightforward framework for understanding why we should think that advanced, complex life exists on planets other than Earth. They provide a unique perspective on the question that puzzled the human species for centuries: are we alone?
