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
In recent years, planetary science has seen a tremendous growth in new knowledge. Deposits of water ice exist at the Moon's poles. Discoveries on the surface of Mars point to an early warm wet climate, and perhaps conditions under which life could have emerged. Liquid methane rain falls on Saturn's moon Titan, creating rivers, lakes, and geologic landscapes with uncanny resemblances to Earth's. Vision and Voyages for Planetary Science in the Decade 2013-2022 surveys the current state of knowledge of the solar system and recommends a suite of planetary science flagship missions for the decade 2013-2022 that could provide a steady stream of important new discoveries about the solar system. Research priorities defined in the report were selected through a rigorous review that included input from five expert panels. NASA's highest priority large mission should be the Mars Astrobiology Explorer Cacher (MAX-C), a mission to Mars that could help determine whether the planet ever supported life and could also help answer questions about its geologic and climatic history. Other projects should include a mission to Jupiter's icy moon Europa and its subsurface ocean, and the Uranus Orbiter and Probe mission to investigate that planet's interior structure, atmosphere, and composition. For medium-size missions, Vision and Voyages for Planetary Science in the Decade 2013-2022 recommends that NASA select two new missions to be included in its New Frontiers program, which explores the solar system with frequent, mid-size spacecraft missions. If NASA cannot stay within budget for any of these proposed flagship projects, it should focus on smaller, less expensive missions first. Vision and Voyages for Planetary Science in the Decade 2013-2022 suggests that the National Science Foundation expand its funding for existing laboratories and establish new facilities as needed. It also recommends that the program enlist the participation of international partners. This report is a vital resource for government agencies supporting space science, the planetary science community, and the public.

Book Description
Mars has been extensively photographed by cameras and compositionally detected by spectrometers onboard orbiters on a global scale, and explored in-situ by landers and rovers at both local and outcrop scales in different locations. The results have proved that the Martian surface is rich in Earth-like geomorphologies, and the study of terrestrial analogs to Mars has been listed as one of the highest priorities of Martian science. With increasing new discoveries by in-situ explorations, Mars exploration has begun to enter the era of focusing on detailed analyses at regional to outcrop levels, rather than global mapping. Analog studies are playing a crucial role in this transition, making this book, which introduces the methodology and provides cases for readers, essentially important.Dozens of sites on Earth have been listed as analog targets for comparative study with the geomorphology, geology, geochemistry, environment and habitability of Mars. However, due to the diversity of landforms and forming mechanisms, and the long history of Mars, no single analog site on Earth can be fully compared to Mars. Nonetheless, the Qaidam Basin has been listed as an unique Mars analog site for studying the red planet's geomorphology, geology, and environmental changes, particularly regarding the evolution of paleolakes on Mars. This kind of setting has always been listed as a top priority for the search of life on Mars.This book contains first-hand information and on-site images obtained by the work's contributing authors, and is an essential read for anyone interested in Martian geomorphology and its evolution processes and history.

Book Description
Dynamic Mars: Recent and Current Landscape Evolution of the Red Planet presents the latest observations, interpretations, and explanations of geological change at the surface or near-surface of this terrestrial body. These changes raise questions about a decades-old paradigm, formed largely in the aftermath of very coarse Mariner-mission imagery in the 1960s, suggesting that much of the interesting geological activity on Mars occurred deep in its past, eons ago. The book includes discussions of (1) Mars’ ever-changing atmosphere and the impact of this on the planet’s surface and near-surface; (2) the possible involvement of water in relatively new, if not contemporary, gully-like flows and slope streaks (i.e. recurring slope lineae); and (3) the identification of a broad suite of agents and processes (i.e. glacial, periglacial, aeolian, meteorological, volcanic, and meteoric) that are actively revising surface and near-surface landscapes, landforms, and features on a local, regional, and hemispheric scale. Highly illustrated and punctuated by data from the most recent Mars missions, Dynamic Mars is a valuable resource for all levels of research in the geological history of Mars, as well as of the three other terrestrial planets. Utilizes observational and model-based data as well as geological context to frame the understanding of the dynamic surface and near-surface of Mars Presents a broad spectrum of highly regarded experts and themes to discuss and evaluate the geological history of late and current Mars Includes extensive and detailed imagery to clearly illustrate these themes, discussions, and evaluations

Book Description
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.

Book Description
Martian surface contains diverse lithologies (from sedimentary rocks to mafic-ultramafic igneous rocks) and ground patterns. These rocks record the late-stage evolution on the Martian surface from a temperate environment with bodies of liquid water to the current cold and hyper-arid environment. The constraints on the key parameters and processes for water-rock interaction, sedimentation of materials, and geomorphological development can provide important insights into the environmental change and habitability on the Martian surface. However, due to the difficulty in accessing Martian samples and limited remote-sensing data available from the Martian surface, most of the mysteries on Mars remain unraveled. In this proposed research topic we will focus on geological settings on Earth that are similar to the conditions on Mars. These Mars analogs are employed to infer possible processes on Mars and their impact on habitability and the search for life. The Mars analogs on Earth span a variety of environments, such as the super-arid sedimentary plains (e.g., the Qaidam Basin in the north of the Tibetan Plateau, the Mojave Basin in the USA, and the Atacama Desert in South America), the subsurface fracture waters in Precambrian cratons (e.g., the Canadian Shield, the Fennoscandian Shield, and the Kaapvaal Craton), high salinity localities (e.g. Laguna de Tírez, salt mines, and deep-sea brines) as well as extremely cold and highly radiative environments (e.g., polar regions, thin atmosphere). These settings on Earth are more accessible for collecting high-quality mineralogical, geochemical, geochronological, and microbiological data by the state-of-the-art facilities. These data can provide a solid cornerstone for us to understand the cycles of water and other life-essential elements, and their impact on habitability and biodiversity in extreme environments on Earth as well as the limits of life and the detection of biosignatures. Such research can also provide vital insights on the search for life on other planets and moons.

Book Description
Mars is the Solar System's other wild, wet, water world. Long believed to have become cold, dead, and dry aeons ago, we now having striking new proof, not only that Mars was a relatively warm and wet place in geologically recent times, but that even today there are vast reserves of water frozen beneath the planet's surface. This compelling new evidence may well boost the chances of a manned mission to Mars sooner, rather than later. The discovery is also forcing a complete rethink about the mechanisms of global planetary change. What does the drastic turn of events on Mars mean for Earth's climate system? Could life have thrived on Mars very recently, and might it survive today in short-term hibernation? Will humans soon be capable of living off the natural resources that Martian hydrogeology has naturally offered us? Will humans one day be capable of setting off the same chain of events that nature has repeatedly triggered to set off warm, wet episodes on Mars? How could Mars be terraformed into a New World? (And should we even contemplate doing so?) This book offers a visually beautiful, scientifically detailed and accurate presentation of the evidence that has forced this new revolution in Mars science. From the reviews:"Long believed to have been cold, dead and dry for eons, there is now striking new proof that not only was Mars a relatively warm and wet place in geologically recent times, but that even today there are vast reserves of water frozen beneath the planet's surface. In this absorbing, beautifully illustrated book, Kargel describes the still-unfolding revolution in our knowledge about the Red Planet and how future concepts of Mars will continue to be molded by new revelations of four billion years of geology". (LUNAR AND PLANETARY INFORMATION BULLETIN)nbsp; From the reviews:" This exhaustive, effusive, and enthusiastic book conveys the excitement of frontline scientific research about as well as can be done. Kargel describes himself as a member of the "Tucson Mafia," a group of scientists in full rebellion against the "Mars Establishment" and its belief in a cold, dry Mars. His ideas are presented in meticulous detail, supported by hundreds of superb pictures, many taken by the author himself. Some--perhaps most--of his ideas are controversial and may ultimately prove to be wrong, as he himself often points out, but we have to applaud the (sometimes career-risking) courage with which he has pursued them. In spite of the large amount of rather technical information, the reader is swept along by the author's enthusiasm in conveying it and ability to integrate it into a coherent vision. The reader also learns about the process of science: the thrill of having a new idea and discussing it with others at conferences and cafes (and bars), the drudgery often involved in pursuing the idea, the perils of the formal review process for publications and grant applications, and the roles played by personality conflicts and power politics. Summing Up: Enthusiastically recommended. All levels. "nbsp;(T. Barker, CHOICE, March 2005)
