Mars Geological Enigmas: From the Late Noachian Epoch to the Present Day presents outstanding questions on the geology of Mars and divergent viewpoints based on varying interpretations and analyses. The result is a robust and comprehensive discussion that provides opportunities for planetary scientists to develop their own opinions and ways forward. Each theme opens with an introduction that includes background on the topic and lays out questions to be addressed. Alternate perspectives are covered for each topic, including methods, observations, analyses, and in-depth discussion of the conclusions. Chapters within each theme reference each other to facilitate comparison and deeper understanding of divergent opinions. Offers a transchronological view of the geological history of Mars, addressing thematic questions from a broad temporal perspective Discusses outstanding questions on Mars from diverging perspectives Includes key questions and answers, as well as a look ahead to which puzzles remain to be solved
On the surface of Mars lies a formation that looks remarkably like a humanoid face. Forever staring up into the vastness of space it has attracted our attention. For some, that is why it is there, beckoning us to come and explore. Others believe that it is simply an odd looking geological landform - a formation carved over the ages by the random forces of nature. It is our imagination and our desire to find other life in the universe that makes us see it as an intelligently crafted object. Opinions about the possibility of life on Mars have changed over the years from Percival Lowell's canals, to the dead planet image by the earlyMarinermissions to Mars, to the enormous volcanoes, great canyon systems, and channels carved by water seen byMariner 9andViking. In the first edition ofThe Martian Enigmas, Dr. Mark J. Carlotto presented a detailed analysis of the controversial Viking photographs. The revised edition greatly expands on his early work, containing new research results that add further support to the claim that these objects may be precisely what many scientists have sought for decades: the first hard evidence that we are not alone.

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
Interpretations of the geological processes operating on Mars are based on our knowledge of processes occurring on Earth. This 2007 book presents contributions from leading planetary geologists to demonstrate the parallels and differences between these two planets, and will therefore be a key reference for students and researchers of planetary science.
The Description for this book, The Geology of Mars, will be forthcoming.
The Mars Science Laboratory is the latest and most advanced NASA roving vehicle to explore the surface of Mars. The Curiosity rover has landed in Gale crater and will explore this region assessing conditions on the surface that might be hospitable to life and paving the way for later even more sophisticated exploration of the surface. This book describes the mission, its exploration and scientific objectives, studies leading to the design of the mission and the instruments that accomplish the objectives of the mission. This book is aimed at all those engaged in Martian studies as well as those interested in the origin of life in other environments. It will be a valuable reference for anyone who uses data from the Mars Science Laboratory. Previously published in Space Science Reviews journal, Vol. 170/1-4, 2012.
