David Harland opens with a review of the robotic probes, namely the Rangers which returned television before crashing into the Moon, the Surveyors which 'soft landed' in order to investigate the nature of the surface, and the Lunar Orbiters which mapped prospective Apollo landing sites. He then outlines the historic landing by Apollo 11 in terms of what was discovered, and how over the next several missions the program was progressively geared up to enable the final three missions each to spend three days on comprehensive geological investigations. He concludes with a review of the robotic spacecraft that made remote-sensing observations of the Moon. Although aimed at the enthusiast, and can be read as an adventure in exploration, the book develops the scientific theme of lunar geology, and therefore will be of use as background reading for undergraduate students of planetary sciences. In addition, with the prospect of a resumption of human missions, it will help journalists understand what Apollo achieved after the 'flags and footprints' of the Apollo 11 landing in July1969 and will commemorate the fortieth anniversary of that momentous event.

Highlighted as a "Commemorative Edition" on the cover, this second edition will have a new Foreword by one of the original astronauts and a short extra section at the end previewing the prospect of a renewal of human exploration of the Moon. It will include new extra high quality graphics which are only now available and 32 pages of colour illustrations.

Topics cover the origin and evolution of life on Earth, the geological, physical and chemical conditions in which life might arise and the detection of extraterrestrial life on other planets and moons. The book also covers the history of our ideas on extraterrestrial life and the origin of life, as well as the ethical, philosophical and educational issues raised by astrobiology. Written to be accessible to students from diverse backgrounds, this text will be welcomed by advanced undergraduates and graduates who are taking astrobiology courses.

Babylon to Voyager and Beyond covers planetary research from the time of the Babylonians and Ancient Greeks through those of Kepler, Galileo and Newton to the modern era of space exploration. It outlines the key observational discoveries and theoretical developments in their historical context, covering not only the numerous successes but also the main failures. Planetary astronomy has come a long way since the Babylonians used their extensive numerical skills to predict the positions of the moon and planets. That progress is the story of this book, ending, as it does, with the considerable discoveries of the space age, and the discoveries of planets around other stars. This account will appeal to both amateur and professional astronomers, as well as those with an interest in the history of science.

Research into the geological processes operating on Mars relies on interpretation of images and other data returned by unmanned orbiters, probes and landers. Such interpretations are based on our knowledge of processes occurring on Earth Terrestrial analog studies therefore play an important role in understanding the geological features observed on Mars. This 2007 book presents direct comparisons between locales on Earth and Mars, and contains contributions from leading planetary geologists to demonstrate the parallels and differences between these two neighboring planets. Mars is characterized by a wide range of geological phenomena that also occur on Earth, including tectonic, volcanic, impact cratering, eolian, fluvial, glacial and possibly lacustrine and marine processes. The book provides terrestrial analogs for data sets from Mars Global Surveyor, Mars Odyssey, Mars Exploration Rovers and Mars Express, and will therefore be a key reference for students and researchers of planetary science.

Meteorite research is fundamental to our understanding of the origin and early history of the Solar System. Some meteorites were produced by melting on asteroids, a few are from the Moon and others are martian. Their study yields a chronology of the first 100 million years of Solar System history and provides evidence that our Sun went through a highly radiative, T Tauri stage. This book considers the mechanism and timing of core formation and basaltic volcanism on asteroids and the effects of heating water-rich bodies. Results from meteorite research are placed in a galactic setting, and a theory is proposed for the origin of the planets of our Solar System. This advanced yet succinct introduction provides a classification of meteorites and discusses their ages and origin. It will be valuable to graduate students and scientists in astrophysics, space research, cosmochemistry, geochemistry, isotope geology and earth and planetary sciences.

They range in size from microscopic particles to masses of many tons. The geologic diversity of asteroids and other rocky bodies of the solar system are displayed in the enormous variety of textures and mineralogies observed in meteorites. The composition, chemistry, and mineralogy of primitive meteorites collectively provide evidence for a wide variety of chemical and physical processes. This book synthesizes our current understanding of the early solar system, summarizing information about processes that occurred before its formation. It will be valuable as a textbook for graduate education in planetary science and as a reference for meteoriticists and researchers in allied fields worldwide.

With the Hubble Space Telepscope's next servicing mission still uncertain, identifying the most crucial science to be performed by this superb telescope has become of paramount importance. With this goal in mind, this book presents a review of some of the most important open questions in astronomy today. World experts examine topics ranging from extrasolar planets and star formation to supermassive black holes and the reionization of the universe. Special emphasis is placed on what astronomical observations should be carried out during the next few years to enable breakthroughs in our understanding of a complex and dynamic universe. In particular, the reviewers attempt to identify those topics to which the Hubble Space Telescope can uniquely contribute. The special emphasis on future research makes this book an essential resource for both professional researchers and graduate students in astronomy and astrophysics.

The space vehicle spectaculars of recent years have been revealing the full scope and beauty of our own solar system but have also shown that a growing number of other stars too have planetary bodies orbiting around them. The study of these systems is just beginning. It seems that our galaxy contains untold numbers of planets, and presumably other galaxies will be similar to our own. Our solar system contains life, on Earth: do others as well? Such questions excite modern planetary scientists and astro-biologists. This situation is a far cry from ancient times when the five planets that can be seen from Earth without a telescope were called the "wandering stars".This notebook-cum-workbook provides an introduction to those profound and still-developing modern studies. Written by an expert in the field, it is pitched at a level suitable for beginning students. It is designed particularly for self-study but can also provide background support for students attending lecture courses or teachers developing such courses. The reader is encouraged to add to the arguments of the book as the subject develops. A special feature here is a substantial glossary of terms and people which serves as a starting point for further entries. Wandering Stars is a key to unlock the door to an exciting and fascinating universe which is still the object of active discovery.

Over the last decade the physics of black holes has been revolutionized by developments that grew out of Jacob Bekenstein's realization that black holes have entropy. Stephen Hawking raised profound issues concerning the loss of information in black hole evaporation and the consistency of quantum mechanics in a world with gravity. For two decades these questions puzzled theoretical physicists and eventually led to a revolution in the way we think about space, time, matter and information. This revolution has culminated in a remarkable principle called "The Holographic Principle", which is now a major focus of attention in gravitational research, quantum field theory and elementary particle physics. Leonard Susskind, one of the co-inventors of the Holographic Principle as well as one of the founders of String theory, develops and explains these concepts.

This completely rewritten new edition begins with an historical perspective of the place of the solar system in the universe. Evidence from meteorites is used to describe how the planets were formed and the giant planets are considered in the light of the discovery of new extrasolar giants. Other chapters discuss satellites, comets, centaurs, asteroids and why Pluto is not a planet. Explanations on why Earth and Venus turned out so differently, and how Mars and Mercury are the survivors of many similar bodies, are also discussed. The formation of the Moon in a giant impact leads to an assessment of the importance of collisions and impacts in the solar system. It is concluded that our solar system is the end product of many accidental and chance events. This leads to the philosophical discussion of whether planets like our Earth are likely to be found elsewhere in the universe.

Chondrites are the largest group of meteorites. They can provide unique insights into the origins and early evolution of our Solar System, and even into the relationships between our Solar System and other stars in the vicinity of our Sun. The largest structural components of most chondrites are the glass-bearing chondrules, and there are numerous theories for their origin. This clear and systematic text summarizes the ideas surrounding the origin and history of chondrules and chondrites, drawing on research from the various scientific disciplines involved. With citations to a large number of published papers on the topic, it forms a comprehensive bibliography of the key research areas, and extensive illustrations provide a clear visual representation of the scientific theories. This text will be a valuable reference for graduate students and researchers in planetary science, geology, and astronomy.

With the discovery in 1995 of the first planet orbiting another star, we now realize that planets are not unique to our own Solar System. For centuries, humanity has wondered whether we are alone in the Universe. We are now finally one step closer to knowing the answer. The quest for exoplanets is an exciting one because it holds the possibility that one day we might find life elsewhere in the Universe, born in the light of another sun. Written from the perspective of one of the pioneers of this scientific adventure, this exciting account describes the development of the modern observing technique that has enabled astronomers to find so many planets orbiting around other stars. It reveals the wealth of new planets that have now been discovered outside our Solar System, and the meaning of this finding as it concerns other life in the Universe. Michel Mayor is Director of the Observatory of Geneva, Switzerland. In 1995, together with Didier Queloz, he discovered the first extrasolar planet (51 Peg b) around a main sequence star, and has discovered many more since. His work earned him the prestigious Balzan Prize in 2000, for Instrumentation and Techniques in Astronomy and Astrophysics. Pierre-Yves Frei is a science journalist with the Swiss newspaper, Lausanne Hebdo. In 1998 he was awarded the Media Prize of the Swiss Natural Sciences Academy for science popularization. Boud Roukema is the translator.

With the development of space-travel, we have begun to explore worlds beyond Earth. Ten planetary scientists describe their favorite planet, what they have discovered, and what drives them to explore. Each tells a personal story, ranging across the breadth of the solar system--from hellish Mercury to the snows of Pluto; from telescopic to robotic exploration; from adventures in Antarctica to painting planetary landscapes; from the frustration of failure to the joy of success. Worlds Beyond is the third in a series of books bringing together leading space scientists to describe their work. Our Worlds was the first of its kind in revealing the inner motivations of planetary scientists. Our Universe explored the vastness of the Universe itself. Now, with Worlds Beyond, we return to our home--the solar system--to visit those fascinating new worlds beyond our own. S. Alan Stern is Director of the Department of Space Studies at Southwest Research Institute in Boulder, Colorado. He is a planetary scientist and astrophysicist with observational and theoretical interests. Stern is an avid pilot and a principal investigator in NASA's planetary research program, and he was selected to be a NASA space shuttle mission specialist finalist. He is the author of more than one hundred papers and popular articles. He is also the author of Pluto & Charon (Wiley, 1997).

Lifting Titan's Veil is a revealing account of the second largest moon in our solar system. This world in orbit around Saturn is the only body in the solar system with an atmosphere strikingly similar to Earth's. Titan is like a giant frozen laboratory that may help scientists understand the first chemical steps towards the origin of life. Beginning with its discovery in 1655, the authors describe our current knowledge of Titan, including observations made before the space age, results from the Voyager missions of the 1980s, and recent revelations from the world's most advanced telescopes. In Lifting Titan's Veil, Ralph Lorenz includes his personal experiences in preparing for the Cassini mission, which will reach Saturn in 2004 and release the Huygens probe into Titan's atmosphere in 2005. A splendid introduction to Titan, this book will appeal to anyone interested in astronomical discovery and space exploration. Ralph Lorenz trained as an engineer and worked for the European Space Agency at the very beginning of the Huygens project. Since obtaining a PhD at the University of Kent, England, he has worked as a planetary scientist at the University of Arizona, Tucson. His research interests focus on Titan, but also include climatology, radar, impact dynamics and spacecraft and instrumentation design. He has been involved in NASA's largest planetary mission (Cassini) and its smallest (the DS-2 Mars Microprobes). Jacqueline Mitton obtained a Ph.D in astrophysics from the University of Cambridge, and is now a full-time writer and media consultant specializing in astronomy. She has served as Press Officer for the Royal Astonomical Society since 1989, and was Editor of the Journal of the British Astronomical Association 1989-1993. She has written or co-authored sixteen published astronomy books, the most recent, The Cambridge Dictionary of Astronomy (2001).

Exactly what is beyond Pluto? Why, in the last ten years, has the Solar System more than doubled in size? For the first time, in almost two centuries, an entirely new population of planetary objects has been found that may well explain these two questions. This newly discovered realm of minor planets, now known as the "Kuiper Belt," has reconceptualized our understanding of how the Solar System was formed and has finally given ontological explanations for the enigmatic outer planet Pluto. Beyond Pluto is the fascinating story of how a group of theoretical physicists decided that there must be a population of unknown bodies beyond Pluto and how a small band of astronomers set out to find them. Acclaimed scientist John K. Davies recounts how they predicted the existence of these planetary bodies, how they were eventually discovered, and how Pluto was named. In addition, Davies provides biographies of the astronomers who discovered these new worlds and information on the telescopes they used. John K. Davies is a support scientist for the UK Infrared Telescope (UKIRT) atop the dormant volcano Mauna Kea in Hawaii. He holds PhDs in chemistry and astronomy, discovered six comets while teaching at Leicester University in the UK, and was a member of the ISO-CAM team at the Royal Observatory in Edinburgh, Scotland. He has contributed to magazines such as Astronomy, New Scientist, Sky & Telescope, and Space. In 2000, a small main asteroid belt was named Johndavies in recognition of his numerous contributions to astronomy.

Here is an informative, up-to-date and well-illustrated guide to planetary observations for amateurs. After chapters on the solar system and the celestial sphere, the text explains how to choose, test and use a telescope with various accessories and how to make observations and record results. For each planet and the asteroids, Price gives details of observational techniques, together with suggestions for how to make contributions of sound astronomical value. From a general description and detailed observational history of each planet, readers learn how to anticipate what they should see and assess their own observations. New to this edition is a chapter on planetary photography that includes the revolutionary use of videography, charge coupled devices and video-assisted drawing. Another new feature is a section on the Kuiper Belt and Oort Cloud. Other chapters on making maps and planispheres and on photoelectric photometry round out the book's up-to-date treatment, making this indispensable reading for both casual and serious observer alike.

Most scientists now agree that some sixty-five million years ago, an immense comet slammed into the Yucatan, detonating a blast twenty million times more powerful than the largest hydrogen bomb, punching a hole ten miles deep in the earth. Trillions of tons of rock were vaporized and launched into the atmosphere. For a thousand miles in all directions, vegetation burst into flames. There were tremendous blast waves, searing winds, showers of molten matter from the sky, earthquakes, and a terrible darkness that cut out sunlight for a year, enveloping the planet in freezing cold. Thousands of species of plants and animals were obliterated, including the dinosaurs, some of which may have become extinct in a matter of hours. In Impact, Gerrit L. Verschuur offers an eye-opening look at such catastrophic collisions with our planet. Perhaps more important, he paints an unsettling portrait of the possibility of new collisions with earth, exploring potential threats to our planet and describing what scientists are doing right now to prepare for this awful possibility.
Every day something from space hits our planet, Verschuur reveals. In fact, about 10,000 tons of space debris fall to earth every year, mostly in meteoric form. The author recounts spectacular recent sightings, such as over Allende, Mexico, in 1969, when a fireball showered the region with four tons of fragments, and the twenty-six pound meteor that went through the trunk of a red Chevy Malibu in Peekskill, New York, in 1992 (the meteor was subsequently sold for $69,000 and the car itself fetched $10,000). But meteors are not the greatest threat to life on earth, the author points out. The major threats are asteroids and comets. The reader discovers that astronomers have located some 350 NEAs ("Near Earth Asteroids"), objects whose orbits cross the orbit of the earth, the largest of which are 1627 Ivar (6 kilometers wide) and 1580 Betula (8 kilometers). Indeed, we learn that in 1989, a bus-sized asteroid called Asclepius missed our planet by 650,000 kilometers (a mere six hours), and that in 1994 a sixty-foot object passed within 180,000 kilometers, half the distance to the moon. Comets, of course, are even more deadly. Verschuur provides a gripping description of the small comet that exploded in the atmosphere above the Tunguska River valley in Siberia, in 1908, in a blinding flash visible for several thousand miles (every tree within sixty miles of ground zero was flattened). He discusses Comet Swift-Tuttle--"the most dangerous object in the solar system"--a comet far larger than the one that killed off the dinosaurs, due to pass through earth's orbit in the year 2126. And he recounts the collision of Comet Shoemaker-Levy 9 with Jupiter in 1994, as some twenty cometary fragments struck the giant planet over the course of several days, casting titanic plumes out into space (when Fragment G hit, it outshone the planet on the infrared band, and left a dark area at the impact site larger than the Great Red Spot). In addition, the author describes the efforts of Spacewatch and other groups to locate NEAs, and evaluates the idea that comet and asteroid impacts have been an underrated factor in the evolution of life on earth.
Astronomer Herbert Howe observed in 1897: "While there are not definite data to reason from, it is believed that an encounter with the nucleus of one of the largest comets is not to be desired." As Verschuur shows in Impact, we now have substantial data with which to support Howe's tongue-in-cheek remark. Whether discussing monumental tsunamis or the innumerable comets in the Solar System, this book will enthrall anyone curious about outer space, remarkable natural phenomenon, or the future of the planet earth.

This book reviews the physics of the concept of solar forcing, or driving, of climate change in manageable terms, tracing its history from its beginnings in the early 1800s to a resurgence of interest in the idea in recent years. Emphasis is on solar variation as a driver for climate change; other mechanisms are treated briefly.

Twenty years after the Viking missions of the '70s, we are finally going back to Mars. No fewer than ten missions are planned for the period between 1996 and 2003, and it is likely that human explorers will follow soon after--perhaps by the middle of the twenty-first century. When they do, they will owe much to the Mars of romance, to the early pioneers whose discoveries and disappointments are brought to life in "The Planet Mars: A History of Observation and Discovery." In this timely and vividly written account, William Sheehan traces human fascination with Mars back to the naked-eye observers of the planet. He recalls the early telescopic observers who first made out enigmatic markings and polar caps on its surface. Through lively historical anecdotes, he describes in detail the debate over the so-called canals of Mars, which encouraged speculation that the planet might be inhabited. Finally, Sheehan describes more recent theories about the planet, leading up to the present, when unmanned spacecraft have enabled us to make giant strides in exploration. Well documented and sparked with human interest, this book will be a useful companion and guide in interpreting the barrage of headlines about Mars that is sure to come over the next few years. Amateurs will appreciate the contributions that have been made to Martian studies by people like themselves, and professionals will find much original material that has never before been published. The American Mars Global Surveyor is scheduled for launch in November 1996, and soon after the American Mars Pathfinder will make its way toward the red planet. A Russian mission consisting of an orbiter and two landers will be launched in October 1997. These space travelers will write a whole new chapter in the dramatic story of Mars, a planet whose exploration has only just begun.

The magnetosphere is the region in which the solar wind interacts with the Earth's magnetic field, the zone which screens the Earth from most of the harmful cosmic rays which daily bombard it. The Aurora Borealis, or Norhun lights, other such phenourena result from the interaction of particles in the solar wind and the magnetosphere. Planetary physicists, geophysicists, plasma astrophysicists, and scientists involved with astronautics all have a primary interest in the configuration and dynamics of the magnetosphere, and much research is devoted to convection (the circulation of solarwind plastma in the magnetiosphere) and substorms, which are linked to the aurorae and thought to stimulate convection. In this book, one of the leading scientists in the field presents a synthesis of current knowledge on convection and substorms and proposes that the Planetary physicists, geophysicists, plasma astrophysicists, and scientists involved with astronautics all have a primary interest in the configuration and dynamics of the magnetosphere, and much research is devoted to convection (the circulation of solarwind plastma in the magnetiosphere) and substorms, which are linked to the aurorae and thought to stimulate convection. In this book, one of the leading scientists in the field presents a synthesis of current knowledge on convection and substorms and proposes that the steady reconnection model be replaced by a model of multiple tail reconnection events, in which many mutually interdependent reconnections occur.

This book follows the development of research on the origin of the Moon from the late 18th century to the present. By gathering together the major texts, papers, and events of the time, it provides a thorough chronicle of the paradigmatic shift in planetary science that arose from the notion that the Earth-Moon system was formed from two colliding planetary bodies. The book covers pre-Apollo ideas, the conceptual evolution during and subsequent to the Apollo explorations of the Moon, and the development of the Earth-Moon system consensus. A plethora of excerpts from key publications are included to demonstrate the shift in scientific focus over the centuries. Through its comprehensive review of lunar science research and literature, this book shows how new technologies and discoveries catalyzed the community and revolutionized our understanding of the Moon's formation.
