How can we tell that meteorite ALH 84001 comes from Mars, and what is it doing on Earth?! This meteorite, found in Antarctica in 1984, provided scientists with evidence suggesting the possibility that life once existed on Mars. Dr. Fred Bortz uses the scientific process to break down what we know, and what we are still learning. Newly updated (2014) to include data acquired by the Spirit, Opportunity and Curiosity rovers.

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.

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.

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

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.
