Book Description
The Lunar Surface Layer: Materials and Characteristics focuses on the characteristics, nature, and materials located in the lunar surface layer, including lunar soil mechanics, water vapor adsorption, and soil behavior. The selection first elaborates on soil mechanics considerations in the testing of lunar soil models, an experimental study in lunar soil mechanics, and gravity effects on soil behavior. Discussions focus on cohesion in lunar soils, gravity effect on dynamic shear strength of soils, porosity, soil bearing strength, lunar effects, soil cohesion in the lunar environment, gradation, structure and contact characteristics, and statics and dynamics. The book then examines the investigation of soil adhesion under high vacuum; water vapor adsorption behavior of kaolinite after high-vacuum storage; and sonic velocity and shear strength of possible lunar surface materials. Concerns cover shear strength, sonic velocity, experimental apparatus, and calibration. The manuscript takes a look at the consideration of properties of simulated lunar soil with possible stabilization techniques; feasibility of remote compositional mapping of the lunar surface; thermal emission characteristics of mineral dusts; and thermal properties of postulated lunar surface materials. The selection is highly recommended for researchers wanting to study the lunar surface layer.

Book Description
The Lunar Reconnaissance Orbiter (LRO) was successfully launched on June 18, 2009 and joined an international eet of satellites (Japan’s SELENE/Kaguya, China’s Chang’E, and India’s Chandrayaan-1) that have recently orbited the Moon for scienti c exploration p- poses. LRO is the rst step to ful ll the US national space goal to return humans to the Moon’s surface, which is a primary objective of NASA’s Exploration Systems Mission - rectorate (ESMD). TheinitialLROmissionphasehasaone-yeardurationfullyfundedunder ESMD support. LRO is expected to have an extended phase of operations for at least two additional years to undertake further lunar science measurements that are directly linked to objectives outlined in the National Academy of Science’s report on the Scienti c Context for Exploration of the Moon (SCEM). All data from LRO will be deposited in the Planetary Data System (PDS) archive so as to be usable for both exploration and science by the widest possible community. A NASA Announcement of Opportunity (AO) solicited proposals for LRO instruments with associated exploration measurement investigations. A rigorous evaluation process - volving scienti c peer review, in combination with technical, cost and management risk assessments, recommended six instruments for LRO development and deployment. The competitively selected instruments are: Cosmic Ray Telescope for the Effects of Rad- tion (CRaTER), Diviner Lunar Radiometer Experiment (DLRE), Lyman-Alpha Mapping Project (LAMP), Lunar Exploration Neutron Detector (LEND), Lunar Orbiter Laser - timeter (LOLA), and Lunar Reconnaissance Orbiter Camera (LROC).

Book Description
Volume 60 of Reviews in Mineralogy and Geochemistry assesses the current state of knowledge of lunar geoscience, given the data sets provided by missions of the 1990's, and lists remaining key questions as well as new ones for future exploration to address. It documents how a planet or moon other than the world on which we live can be studied and understood in light of integrated suites of specific kinds of information. The Moon is the only body other than Earth for which we have material samples of known geologic context for study. This volume seeks to show how the different kinds of information gained about the Moon relate to each other and also to learn from this experience, thus allowing more efficient planning for the exploration of other worlds.

Book Description
The Encyclopedia of Lunar Science includes the latest topical data, definitions, and explanations of the many and varied facets of lunar science. This is a very useful reference work for a broad audience, not limited to the professional lunar scientist: general astronomers, researchers, theoreticians, practitioners, graduate students, undergraduate students, and astrophysicists as well as geologists and engineers. The title includes all current areas of lunar science, with the topical entries being established tertiary literature. The work is technically suitable to most advanced undergraduate and graduate students. The articles include topics of varying technical levels so that the top scientists of the field find this work a benefit as well as the graduate students and the budding lunar scientists. A few examples of topical areas are as follows: Basaltic Volcanism, Lunar Chemistry, Time and Motion Coordinates, Cosmic Weathering through Meteoritic Impact, Environment, Geology, Geologic History, Impacts and Impact Processes, Lunar Surface Processes, Origin and Evolution Theories, Regolith, Stratigraphy, Tectonic Activity, Topography, Weathering through ionizing radiation from the solar wind, solar flares, and cosmic rays.

Book Description
The Moon held little interest for most scientists after its basic astronomic properties had been determined and before direct exploration appeared likely. Speculations about its internal structure, composition, and origin were only broadly constrained by cosmochemical data from meteorites and solar spectra, and by astronomic data about its size, shape, motions, and surficial properties. Most investigators who were active before the space age began in 1957 believed that significant new advances in lunar knowledge required acquisition of additional data. One analytical technique, however, was insufficiently exploited before the 1960's. Few scientists since the geologist Gilbert had studied the lunar surface systematically from the historical point of view. Those who did immediately obtained important new insights about the Moon's postaccretion evolution. Then, the pioneering work of E.M. Shoemaker and R.J. Hackman focused the powerful methods of stratigraphy on lunar problems. Stratigraphy is the study of the spatial distribution, chronologic relations, and formative processes of layered rocks. Its application to the Moon came relatively late and met resistance, but the fundamental stratigraphic approach was, in fact, readily transferable to the partly familiar, partly exotic deposits visible on the lunar surface. Stratigraphic methods were applied systematically during the 1960's in a program of geologic mapping that aimed at reconstructing the evolution of the Moon's nearside. Order was discovered among the seemingly diverse and random landforms of the lunar surface by determining the sequence in which they were emplaced. The stratigraphic sequence and the emplacement processes deduced therefrom provided a framework for exploration by the Apollo program and for the task of analyzing the returned samples. During the 19703, the sophisticated labor of hundreds of analysts was brought to bear on the wealth of material returned by the American Apollo and the Soviet Luna spacecraft. Our present perception of the Moon has emerged from the interplay between sampling studies and stratigraphically based photogeology. These two approaches are complementary: Photogeology contributes a historical context by viewing the whole Moon from a distant vantage point, whereas the samples contain information on rock types and absolute ages unobtainable by remote methods. Neither approach by itself, even the most elaborate program of direct surface exploration, could have yielded the current advanced state of knowledge within the relatively short time of two decades. This volume presents a model for the geologic evolution of the Moon that has emerged mainly from this integration of photogeologic stratigraphy and sample analysis. Other aspects of the vast field of lunar science are discussed here only insofar as they pertain to the evolution of visible surface features. Chemical data obtained by remote sensing supplement the photogeologic interpretations of some geologic units, and geophysical data obtained both from lunar orbit and on the surface constrain hypotheses of the origin of many internally generated structures and deposits. Studies of the same data that treat the Moon as a whole, including speculations about the intriguing but unsolved problem of its origin, have been adequately covered in other reviews. This volume is written primarily for geoscientists and other planetologists who have examined some aspect of lunar or planetary science and who want a review of lunar science from the viewpoint of historical geology. It should also provide a useful summary for the advanced student who is conversant with common geologic terms. It may, furthermore, interest the geologist who has not studied the Moon but who wishes to see how his methodology has been applied to another planet.
