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

Ices in the Solar-System: A Volatile-Driven Journey from the Inner Solar System to its Far Reaches details the evolution of ice on planetary bodies within the Solar System, including terrestrial planets and the Moon, Ceres and other dwarf planets or volatile asteroids, icy Galilean and Saturnian satellites, Triton and disparate Uranian moons, and Pluto, other Kuyper belt objects and comets. The book provides a view of different ice types throughout the Solar System, i.e., H2O, CO2, CH4, etc., that characterize icy processes on disparate bodies. Ice and icy processes at micro through macro scales are discussed. The book geographically spans the major planetary bodies of the Solar System, covering surface and subsurface geologies, geophysics and geochemistry of ices to answer questions such as the nature and extent of water ice and different frozen volatile species, how do ices give us clues to interiors and oceans, and more. Presents a comprehensive discussion of icy bodies and processes throughout the Solar System and spanning all applicable planetary bodies Discusses ice at the micro-scale (i.e., post nebular origins) to the macro-scale, facilitating our understanding of icy processes and associated landscape evolution through multi-scalar perspectives Describes the disparate ices associated with the geological evolution of bodies large and small throughout the solar system, broadening the focus and highlighting landscape evolution derived of the disparate ice types

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. Some think that 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 forms of 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 early Mariner missions to Mars, to the enormous volcanoes, great canyon systems, and channels carved by water seen by Mariner 9 and Viking. In the first edition of The Martian Enigmas, Dr. Mark J. Carlotto presented a detailed analysis of the controversial Viking photographs. The revised edition greatly expands on his early work and constains new research results that further supports the claim that these objects may be precisely what many scientists have sought for decades: the first hard evidence that we are not alone.

Electrostatic Dust Mitigation and Manipulation Techniques for Planetary Dust explains how to control and remove dust in space due to the presence of a vacuum, abrasiveness of dust particles and electrostatic charge on particles. The book introduces innovative technologies that use electrostatic and di-electrophoretic forces to remove and transport small particles away from surfaces. In addition, it discusses how to resolve thermal control problems and reduce lung inhalation and eye irritation problems. The book includes two abrasive wear test devices that were designed to study the rate of volume wear for di?erent materials when subjected to lunar dust simulant of di?erent size ranges. This will be an ideal resource for space system engineers, space exploration researchers, and advanced students and professionals in space engineering. Provides a comprehensive background on lunar and Martian dust properties and challenges and compares currently available mitigation strategies Highlights the problems from dust on various space systems and crew Features discrete element models which were created and calibrated based on experimental results to study the capacity of the proposed technique for removing and cleaning dust in a planetary environment

This revised and updated edition continues to provide a comprehensive introduction to the subject, exploring the world’s landforms from a broad systems perspective. It covers the basics of Earth surface forms and processes, while reflecting on the latest developments in the field. Fundamentals of Geomorphology begins with a consideration of the nature of geomorphology, including its relation to society, process and form, history, and geomorphic systems, and moves on to discuss: • Structure: structural landforms associated with plate tectonics and those associated with volcanoes, and folds, faults, and joints. • Process and form: landforms resulting from, or influenced by, the exogenic agencies of weathering, running water, flowing ice and meltwater, ground ice and frost, the wind, and the sea; landforms developed on limestone; extraterrestrial landforms; and landscape evolution, a discussion of ancient landforms. Fundamentals of Geomorphology provides a stimulating and innovative perspective on the key topics and debates within the field of geomorphology. Written in an accessible and lively manner, it includes guides to further reading, chapter summaries, and an extensive glossary of key terms. The book is also illustrated throughout with over 200 informative diagrams and attractive photographs, all in colour. It is supported by online resources for students and instructors.

Wetlands are among the world’s most productive environments with countless species of plants and animals, as well as humans, dependent upon them for survival. Moreover, they provide many societal benefits including water quality improvement, flood storage, shoreline erosion control, and opportunities for recreation, education, and research. The conservation of inland wetlands is thus critical, and it is vital that they are protected in situ. The Handbook of Research on Monitoring and Evaluating the Ecological Health of Wetlands highlights the challenges of wetland conservation and current scenarios of existing wetlands and their effective management. The book also promotes the inventory, assessment, and monitoring of wetlands through a discussion of practical approaches, methodologies, and techniques. The strategies covered in this book can be applied in situ, depending on the wetland in which they will be applied. It covers the most cost-effective techniques in conservation of wetland technologies and the most cutting-edge research on monitoring of wetland health and its applications. Covering topics such as forest soil, greenhouse gasses, and ecological rejuvenation, it is an ideal resource for conservators, environmentalists, executives, policymakers, government officials, professionals, researchers, academicians, and students working in ecological management and wetland conservation fields.
