Book Synopsis From Habitability to Life on Mars by : Nathalie A. Cabrol
Download or read book From Habitability to Life on Mars written by Nathalie A. Cabrol and published by Elsevier. This book was released on 2018-07-10 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: The Space Studies Board of the National Research Council (NRC) serves as the primary adviser to the National Aeronautics and Space Administration (NASA) on planetary protection policy, the purpose of which is to preserve conditions for future biological and organic exploration of planets and other solar system objects and to protect Earth and its biosphere from potential extraterrestrial sources of contamination. In October 1995 the NRC received a letter from NASA requesting that the Space Studies Board examine and provide advice on planetary protection issues related to possible sample-return missions to near-Earth solar system bodies.
Book Synopsis Mars: Evidence of Life: : Evolution, Algae, Viking, Alh8401, Stromatolites, Fungi, Bones, Skulls, Methane, Martians by : Rhawn Gabriel Joseph
Download or read book Mars: Evidence of Life: : Evolution, Algae, Viking, Alh8401, Stromatolites, Fungi, Bones, Skulls, Methane, Martians written by Rhawn Gabriel Joseph and published by . This book was released on 2018-02-28 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 100 photos taken by NASA of specimens resembling living or fossilized Martian organisms and evidence for the evolution of past and current life on Mars are reviewed. Billions of years ago Mars was flush with rivers, oceans, and microbiological activity as based on surface details and an analyses of Martian meteor ALH 8401. Fossilized stromatolites have also been identified on the surface of Mars and which were most likely constructed by cyanobacteria. There is evidence Martian microbes continue to flourish as based on the results from the Viking Labeled Release studies. In addition, there is a significant waxing and waning of methane within the Martian atmosphere and at ground level within the Gale Crater and whose most plausible source is living organisms. Within the Gale Crater, Martian fungi, some which have been photographed growing out of the ground and littering the surrounding surface with spores, have been identified by 70 experts in geology and biology who formed a statistically significant consensus that there is life on Mars. Moreover, fungi have been photographed growing atop the rovers Curiosity and Opportunity, and within the rover Curiosity aluminum wheels which appear to have suffered severe biodeterioration. A multi-tentacled specimen photographed within a Gale Crater crevice has also been identified as a biological organism by a majority of geologists; though if the creature is fossilized or alive is unknown. A fossilized skeletal impression of a multi-tentacled specimen has been photographed in the same general vicinity. Additionally, fungi within and beneath Gale Crater Martian rock shelters grow in size, but in some locations, completely or nearly disappear or wane in size which raises the possibility they may have been consumed by parasitic fungi or other organisms. Then there are "anomalies" photographed by NASA which resemble fossilized creatures as well as skulls, bones, skeletal remains suggestive of complex and intelligent life, including debris fields which appear to be strewn with wreckage, tools, and the remains of Martians or other aliens. What they are, is unknown. The evidence compiled in this book demonstrates that various microorganisms and eukaryotes (fungi) have successfully colonized the Red Planet and that complex Martian life forms may have evolved on Mars.

Book Synopsis Life on Mars Exposed (Revised) by : Raymond Cullis
Download or read book Life on Mars Exposed (Revised) written by Raymond Cullis and published by ThreeCatsPub. This book was released on 2023-05-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 202 pages in length, over 170 pages of which are full-page, full color-photos of evidence of life on Mars. While NASA continues to spend billions in search of life on the Red Planet, the author spent only $500 for a computer to access Google Earth's Mars mode for his discoveries. And, instead of trying to convince readers with words that there is proof of past and present life on Mars, he uses photographs screen-captured from Mars itself. So the evidence is in the images for readers to see for themselves. The author doesn't spend time denouncing NASA for not admitting that it has already found life on Mars, because he's convinced that the space agency is being kept from disclosing the fact by other "decision makers." He believes this because of a statement made in The Brookings Report, a think thank that was commissioned by NASA to write, "Proposed Studies on the Implications of Peaceful Space Activities for Human Affairs." That study can be found online by simple searching the words, "The Brookings Report." One statement in that report says NASA might consider the option to "withhold from the public" its discovery of extraterrestrial life, if it found such life. But NASA would, obviously have to acquiesce to higher authority to make that decision. The author does not dwell on this unfortunate situation, but devotes this book to displaying what he believes is convincing evidence, if not outright proof of intelligent life on Mars, not just in the past but in the present time. Knowledge of life on Mars will usher in a new era of planet and space exploration. We are not alone in the universe, and for that we should be thankful, not terrified.
Book Synopsis Discovering Mars by : William Sheehan
Download or read book Discovering Mars written by William Sheehan and published by University of Arizona Press. This book was released on 2021-11-09 with total page 769 pages. Available in PDF, EPUB and Kindle. Book excerpt: For millenia humans have considered Mars the most fascinating planet in our solar system. We’ve watched this Earth-like world first with the naked eye, then using telescopes, and, most recently, through robotic orbiters and landers and rovers on the surface. Historian William Sheehan and astronomer and planetary scientist Jim Bell combine their talents to tell a unique story of what we’ve learned by studying Mars through evolving technologies. What the eye sees as a mysterious red dot wandering through the sky becomes a blurry mirage of apparent seas, continents, and canals as viewed through Earth-based telescopes. Beginning with the Mariner and Viking missions of the 1960s and 1970s, space-based instruments and monitoring systems have flooded scientists with data on Mars’s meteorology and geology, and have even sought evidence of possible existence of life-forms on or beneath the surface. This knowledge has transformed our perception of the Red Planet and has provided clues for better understanding our own blue world. Discovering Mars vividly conveys the way our understanding of this other planet has grown from earliest times to the present. The story is epic in scope—an Iliad or Odyssey for our time, at least so far largely without the folly, greed, lust, and tragedy of those ancient stories. Instead, the narrative of our quest for the Red Planet has showcased some of our species’ most hopeful attributes: curiosity, cooperation, exploration, and the restless drive to understand our place in the larger universe. Sheehan and Bell have written an ambitious first draft of that narrative even as the latest chapters continue to be added both by researchers on Earth and our robotic emissaries on and around Mars, including the latest: the Perseverance rover and its Ingenuity helicopter drone, which set down in Mars’s Jezero Crater in February 2021.

Book Synopsis Life on Mars by : David A. Weintraub
Download or read book Life on Mars written by David A. Weintraub and published by Princeton University Press. This book was released on 2020-11-03 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Does life exist on Mars? The question has captivated humans for centuries, but today it has taken on new urgency. NASA plans to send astronauts to Mars orbit by the 2030s. SpaceX wants to go by 2024, while Mars One wants to land a permanent settlement there in 2032. As we gear up for missions like these, we have a responsibility to think deeply about what kinds of life may already inhabit the planet -- and whether we have the right to invite ourselves in. This book tells the complete story of the quest to answer one of the most tantalizing questions in astronomy. But it is more than a history. Life on Mars explains what we need to know before we go."--From Amazon.com.

Book Synopsis Human Missions to Mars by : Donald Rapp
Download or read book Human Missions to Mars written by Donald Rapp and published by Springer Nature. This book was released on 2023-01-01 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, Donald Rapp looks at human missions to Mars from a technological perspective. He divides the mission into a number of stages: Earth’s surface to low-Earth orbit (LEO); departing from LEO toward Mars; Mars orbit insertion and entry, descent and landing; ascent from Mars; trans-Earth injection from Mars orbit and Earth return. A mission to send humans to explore the surface of Mars has been the ultimate goal of planetary exploration since the 1950s, when von Braun conjectured a flotilla of 10 interplanetary vessels carrying a crew of at least 70 humans. Since then, more than 1,000 studies were carried out. This third edition provides extensive updating and additions to the last edition, including new sections, and many new figures and tables, and references.

Book Synopsis Is Mars Habitable? by : Alfred Russel Wallace
Download or read book Is Mars Habitable? written by Alfred Russel Wallace and published by IndyPublish.com. This book was released on 1907 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The special point to which I here wish to call attention is this. Mr. Lowell's main contention is, that the surface of Mars is wonderfully smooth and level. Not only are there no mountains, but there are no hills or valleys or plateaux. This assumption is absolutely essential to support the other great assumption, that the wonderful network of perfectly straight lines over nearly the whole surface of the planet are irrigation canals. It is not alleged that irregularities or undulations of a few hundreds or even one or two thousands of feet could possibly be detected, while certainly all we know of planetary formation or structure point strongly towards some inequalities of surface.
