Growing evidence, based on observations from orbiters, landers and telescopes, indicates that Mars may still have numerous hidden water reservoirs. "Water on Mars and Life" surveys recent advances made in research into water on Mars together with its astrobiological implications. Addresses not only scientists working in the field but also nonspecialists and students in search of a high-level but accessible introduction to this exciting field of research.

Provides a comprehensive account of the recent ‘Spirit’ and ‘Opportunity’ Mars Exploration Rover missions. Relates how NASA/ESA have sought evidence of life on Mars, with the prevailing mood sometimes being optimistic and sometimes pessimistic. Details an account of the rationale for the tests for life carried out by the Viking missions in 1976, with an account of the debate over their results. A concise primer for readers wishing to ‘bone up’ when NASA next sends a lander explicitly to seek life on Mars. Discusses the nature of life on Mars in terms of the most primitive forms of life on Earth, and reviews the implications of there being life on both planets.

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

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Pages: 40. Chapters: Evidence of water on Mars found by Mars Reconnaissance Orbiter, Evidence of water on Mars from Mars Odyssey, Groundwater on Mars, Mars ocean hypothesis, Timeline of discoveries of water on Mars, Water on terrestrial planets. Excerpt: Water on Mars exists almost exclusively as water ice. The Martian polar ice caps consist primarily of water ice, and further ice is contained in Martian surface rocks at more temperate latitudes (permafrost). A small amount of water vapor is present in the atmosphere. There are no bodies of liquid water on the Martian surface. Current conditions on the planet surface do not support the long-term existence of liquid water. The average atmospheric pressure and temperature are far too low, leading to immediate freezing and resulting sublimation. Despite this, research suggests that in the past there was liquid water flowing on the surface, creating large areas similar to Earth's oceans. According to Steve Squyres, Principal investigator of the Mars Exploration Rover Missions (MER): "The idea been resolved. It's been resolved by Spirit, it's been resolved by Opportunity, it's been resolved by Curiosity, it's been amply resolved from orbit as well." There are a number of direct and indirect proofs of water's presence either on or under the surface, e.g. stream beds, polar caps, spectroscopic measurement, eroded craters or minerals directly connected to the existence of liquid water (such as goethite), grey, crystalline hematite, phyllosilicates, opal, and sulfate. With the improved cameras on advanced Mars orbiters such as Viking, Mars Odyssey, Mars Global Surveyor, Mars Express, and the Mars Reconnaissance Orbiter pictures of ancient lakes, ancient river valleys, and widespread glaciation have accumulated. Besides the visual confirmation of water from a huge collection of images, an...

This book provides an overview of the discovery of liquid water on Mars and the physical and geochemical processes that cause liquid saline water to form and stabilize in cold and dry environments such as the shallow martian subsurface and some areas of the polar region. The book also analyzes the implications of the discovery of liquid water for microbial life on Mars, the most Earth-like planet in the solar system. It explores the applications of scaling and thermodynamics to planetary sciences and explains how these concepts led to the discovery of liquid saline water on Mars. It covers the fundamental concepts necessary to understand the stability of liquid water in planetary environments.

Within the Office of Space Science of the National Aeronautics and Space Administration (NASA) special importance is attached to exploration of the planet Mars, because it is the most like Earth of the planets in the solar system and the place where the first detection of extraterrestrial life seems most likely to be made. The failures in 1999 of two NASA missions-Mars Climate Orbiter and Mars Polar Lander-caused the space agency's program of Mars exploration to be systematically rethought, both technologically and scientifically. A new Mars Exploration Program plan (summarized in Appendix A) was announced in October 2000. The Committee on Planetary and Lunar Exploration (COMPLEX), a standing committee of the Space Studies Board of the National Research Council, was asked to examine the scientific content of this new program. This goals of this report are the following: -Review the state of knowledge of the planet Mars, with special emphasis on findings of the most recent Mars missions and related research activities; -Review the most important Mars research opportunities in the immediate future; -Review scientific priorities for the exploration of Mars identified by COMPLEX (and other scientific advisory groups) and their motivation, and consider the degree to which recent discoveries suggest a reordering of priorities; and -Assess the congruence between NASA's evolving Mars Exploration Program plan and these recommended priorities, and suggest any adjustments that might be warranted.

With the cold war over, advocates of colonizing the red planet argue that overpopulation is the direst threat to our home planet and that we an additional one for the overflow. The 54 papers cover building support for low-cost missions, essential technology and proposed infrastructure, scientific and engineering measures for reducing the cost of precursor missions, and designing a habitable planet. Working groups report on such topics as programmatics and philosophy and non-government approaches. There is no subject index. Annotation copyrighted by Book News, Inc., Portland, OR
