The Moon's Near Side Megabasin and Far Side Bulge by Charles Byrne Pdf
Since Luna and Lunar Orbiter photographed the far side of the Moon, the mysterious dichotomy between the face of the Moon as we see it from Earth and the side of the Moon that is hidden has puzzled lunar scientists. As we learned more from the Apollo sample return missions and later robotic satellites, the puzzle literally deepened, showing asymmetry of the crust and mantle, all the way to the core of the Moon. This book summarizes the author’s successful search for an ancient impact feature, the Near Side Megabasin of the Moon and the extensions to impact theory needed to find it. The implications of this ancient event are developed to answer many of the questions about the history of the Moon.
The far side of the Moon, also called the "dark side of the Moon" was unknown to humanity until the Luna and Lunar Orbiter pictures were returned to Earth. This wonderful book contains beautiful photographs and newly-assembled mosaic images of the far side of the Moon, cleaned of transmission, imaging stripes and processing artifacts by today’s computer technology. Byrne’s superb analysis documents the appearance of the features of the far side with beautiful pictures from Lunar Orbiter. Until now, the far side Lunar Orbiter photos have only been available with strong reconstruction lines, but appear here for the first time as complete photographs, unmarred by imaging and processing artifacts.
The Moon's Largest Craters and Basins by Charles J. Byrne Pdf
This most recent book from lunar expert Charles J. Byrne combines the latest comprehensive imagery, topography and gravity data from all three recent Moon missions, Kaguya, Lunar Reconnaissance Orbiter and GRAIL. These major polar-orbit surveys are presented here in compact form for the convenience of amateur and practical astronomers concerned with the Moon. Chosen from the Near and Far Side's large craters and basins over 200 km in diameter, each of the 71 highlighted features is depicted with a two-page presentation of the data that includes false color topographic maps next to the mission images. Additionally, the features are presented in the estimated chronological sequence of their creation, based on a consideration of stratigraphy (overlapping layers from neighboring features) and the relative degradation of surface features. Using this sequence as a way to convey the relative ages of lunar features, the author presents various theories concerning the Moon’s impact and thermal history e.g. the available evidence allows for constraints to be placed on the duration of the Late Heavy Bombardment period. The relationships between impact dynamics and variations in the gravity field of the Moon are also discussed. The new mission data makes possible this renewed conjecture about the history and evolution of the Moon, which is presented here with much worthwhile information for amateurs and professionals alike.
Atlas of the Gravity and Magnetic Fields of the Moon by Jaroslav Klokočník,Jan Kostelecký,Václav Cílek,Aleš Bezděk,Gunther Kletetschka Pdf
This book presents gravity aspects (gravity disturbance, Marussi tensor, two gravity invariants, their certain ratio, the strike angles, and the virtual deformations) which are computed and evaluated for the Moon, using the recent static global gravity field model (GRGM1200A) to degree and order of 600 in spherical harmonic expansion. The magnetic anomaly model and surface topography (from the LOLA mission) are added. Results are shown for the whole Moon, for its segments around the Moon and as zooms for selected impact craters, maria and catenae; they are shortly interpreted and opened for further selenologic applications. The book contains information about the geology of the Moon, together with basic information about the magnetic field, mapping and topography models.
The moon has always been the most obvious feature in our night sky. It is our nearest celestial neighbour, orbiting the earth at an average distance of 384,400 kilometers, and is large enough to display significant detail even to the unaided eye. Our moon has drawn observers since the dawn of humankind, and all people have tried to make sense of the puzzles it poses and the questions it raises. The moon provided our ancient ancestors with one of the earliest means of keeping and measuring time, and many early religions had cults that worshipped it. When it eclipses the sun it provides one of the most awe-inspiring views in nature. In The Moon, celebrated amateur astronomer Bill Leatherbarrow provides expert insight into the history of our study of this compelling astronomical body. Drawing on his own decades of lunar observation, he describes how and why the observation and study of the moon has evolved, particularly in the age of telescopic study. He also offers an overview of current scientific thinking and developments in lunar science since the advent of the Space Age, even providing practical advice on how to make your own observations of the moon. Extensively illustrated with images of the lunar surface taken both from spacecraft and using amateur equipment, this book is an accessible introduction to complex astrophysical concepts that will give all amateur astronomers and anyone fascinated by this natural satellite something to moon over.
Astrophysics of the Solar System by Abbhyankar Pdf

While the Moon was once thought to hold the key to space exploration, in recent decades, the U.S. has largely turned its sights toward Mars and other celestial bodies instead. In The Value of the Moon, lunar scientist Paul Spudis argues that the U.S. can and should return to the moon in order to remain a world leader in space utilization and development and a participant in and beneficiary of a new lunar economy. Spudis explores three reasons for returning to the Moon: it is close, it is interesting, and it is useful. The proximity of the Moon not only allows for frequent launches, but also control of any machinery we place there. It is interesting because recorded deep on its surface and in its craters is the preserved history of the moon, the sun, and indeed the entire galaxy. And finally, the moon is useful because it is rich with materials and energy. The moon, Spudis argues, is a logical base for further space exploration and even a possible future home for us all. Throughout his work, Spudis incorporates details about man's fascination with the moon and its place in our shared history. He also explores its religious, cultural, and scientific resonance and assesses its role in the future of spaceflight and our national security and prosperity.

Reservoir Characterization is a collection of papers presented at the Reservoir Characterization Technical Conference, held at the Westin Hotel-Galleria in Dallas on April 29-May 1, 1985. Conference held April 29-May 1, 1985, at the Westin Hotel—Galleria in Dallas. The conference was sponsored by the National Institute for Petroleum and Energy Research, Bartlesville, Oklahoma. Reservoir characterization is a process for quantitatively assigning reservoir properties, recognizing geologic information and uncertainties in spatial variability. This book contains 19 chapters, and begins with the geological characterization of sandstone reservoir, followed by the geological prediction of shale distribution within the Prudhoe Bay field. The subsequent chapters are devoted to determination of reservoir properties, such as porosity, mineral occurrence, and permeability variation estimation. The discussion then shifts to the utility of a Bayesian-type formalism to delineate qualitative ""soft"" information and expert interpretation of reservoir description data. This topic is followed by papers concerning reservoir simulation, parameter assignment, and method of calculation of wetting phase relative permeability. This text also deals with the role of discontinuous vertical flow barriers in reservoir engineering. The last chapters focus on the effect of reservoir heterogeneity on oil reservoir. Petroleum engineers, scientists, and researchers will find this book of great value.

The Geologic History of the Moon by U S Department of the Interior,Don E. Wilhelms Pdf
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.

New Views of the Moon by Bradley L. Jolliff,Mark A. Wieczorek,Charles K. Shearer,Clive R. Neal Pdf
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.

Measuring the Angular Momentum of Supermassive Black Holes by Laura Brenneman Pdf
Measuring the spin distribution of supermassive black holes is of critical importance for understanding how these black holes and their host galaxies form and evolve over time, yet this type of study is only in its infancy. This brief describes how astronomers measure spin in supermassive black holes using X-ray spectroscopy. It also reviews the constraints that have been placed on the spin distribution in local, bright active galaxies over the past six years, and the cosmological implications of these constraints. Finally, it summarizes the open questions that remain in this exciting new field of research and points toward future discoveries soon to be made by the next generation of space-based observatories.
The Lunar Atmosphere and Dust Environment Explorer Mission (LADEE) by Richard C. Elphic,Christopher T. Russell Pdf
This volume contains five articles describing the mission and its instruments. The first paper, by the project scientist Richard C. Elphic and his colleagues, describes the mission objectives, the launch vehicle, spacecraft and the mission itself. This is followed by a description of LADEE’s Neutral Mass Spectrometer by Paul Mahaffy and company. This paper describes the investigation that directly targets the lunar exosphere, which can also be explored optically in the ultraviolet. In the following article Anthony Colaprete describes LADEE’s Ultraviolet and Visible Spectrometer that operated from 230 nm to 810 nm scanning the atmosphere just above the surface. Not only is there atmosphere but there is also dust that putatively can be levitated above the surface, possibly by electric fields on the Moon’s surface. Mihaly Horanyi leads this investigation, called the Lunar Dust Experiment, aimed at understanding the purported observations of levitated dust. This experiment was also very successful, but in this case their discovery was not the electrostatic levitation of dust, but that the dust was raised by meteoroid impacts. This is not what had been expected but clearly is the explanation that best fits the data. Originally published in Space Science Reviews, Volume 185, Issue 1-4, 2014.
