From Mars to Greenland: Charting Gravity With Space and Airborne Instruments


Book Description

Precise and continuous tracking with multi-satellite systems of aircraft andlow flying satellites, accurate airborne measurement of gravity and gravity gradients, and satellite gradiometry have fundamentally changed our view on the de- termination of the Earth's gravity field. The papers in this volume describe these techniques in detail. The ideas are presentedas complementary, and are used to develop new theoretical concepts of gravity field analysis. Computatio- nal models using these techniques are also discussed and are tested in simulations. The papers presented in this volume are the result of an IAG symposium held during the XX General Assembly of the Inter- national Union of Geodesy and Geophysics in Vienna, Austria, August 11-24, 1991.

The Book of Mars


Book Description

From myth to Musk, astrology to astronomy, Dr Stuark Clark selects the very best writing about the Red Planet. From its very first sighting, Mars has been a source of fascination for humanity. Named for the Roman god of war, this red planet has been explored more than any other beyond Earth and continues to occupy a distinctive place in our imagination. It's an environment that may even foster life. In The Book of Mars, Dr Stuart Clark selects one hundred pieces of writing about the planet. It is a collection that brings together fact and fiction, dreams and fears, centuries of observation and more recent feats of interstellar exploration. From classic writers of science fiction – Stanley G. Weinbaum, Arthur C. Clarke, H.G. Wells, Ray Bradbury, Pamela Sargent, Roger Zelazny – to distinguished experts in astronomy, astrobiology and aerospace engineering; from Hugo and Nebula Award-winning authors – Kim Stanley Robinson, Mary Robinette Kowal – to trail-blazing journalists and science communicators; from Andy Weir's The Martian to Elon Musk's SpaceX programme, The Book of Mars is an extraordinary overview both of the Red Planet and of the way scientific investigation diffuses into culture.




The Search for Life on Mars


Book Description

With a focus of the Perseverance rover mission, here is the "Quintessential account of one of humanity’s most intriguing quests" (Pail Halpern, Medium), "A remarkable, timely, and up-to-date account of Mars exploration" (Leonard David, "Space Insider," Space.com). From The War of the Worlds to The Martian and to the amazing photographs sent back by the robotic rovers Curiosity and Opportunity, Mars has excited our imaginations as the most likely other habitat for life in the solar system. Now the Red Planet is coming under scrutiny as never before. As new missions are scheduled to launch this year from the United States and China, and with the European Space Agency's ExoMars mission now scheduled for 2022, this book recounts in full the greatest scientific detective story ever. For the first time in forty years, the missions heading to Mars will look for signs of ancient life on the world next door. It is the latest chapter in an age‑old quest that encompasses myth, false starts, red herrings, and bizarre coincidences—as well as triumphs and heartbreaking failures. This book, by two journalists with deep experience covering space exploration, is the definitive story of how life's discovery has eluded us to date, and how it will be found somewhere and sometime this century. The Search for Life on Mars is based on more than a hundred interviews with experts at NASA’s Jet Propulsion Laboratory and elsewhere, who share their insights and stories. While it looks back to the early Mars missions such as Viking 1 and 2, the book's focus is on the experiments and revelations from the most recent ones—including Curiosity, which continues to explore potentially habitable sites where water was once present, and the Mars Insight lander, which has recorded more than 450 marsquakes since its deployment in late 2018—as well as on the Perseverance and ExoMars rover missions ahead. And the book looks forward to the newest, most exciting frontier of all: the day, not too far away, when humans will land, make the Red Planet their home, and look for life directly.

Imagining Mars


Book Description

Mars in the human imagination from the invention of the telescope to the present For centuries, the planet Mars has captivated astronomers and inspired writers of all genres. Whether imagined as the symbol of the bloody god of war, the cradle of an alien species, or a possible new home for human civilization, our closest planetary neighbor has played a central role in how we think about ourselves in the universe. From Galileo to Kim Stanley Robinson, Robert Crossley traces the history of our fascination with the red planet as it has evolved in literature both fictional and scientific. Crossley focuses specifically on the interplay between scientific discovery and literary invention, exploring how writers throughout the ages have tried to assimilate or resist new planetary knowledge. Covering texts from the 1600s to the present, from the obscure to the classic, Crossley shows how writing about Mars has reflected the desires and social controversies of each era. This astute and elegant study is perfect for science fiction fans and readers of popular science.

The Assembly was successfully held in Shanghai, China from June 30th to July 6th, 2014 with over 130 participants from 25 countries. The focus of the Assembly is on methods for observing, estimating and interpreting the Earth gravity field as well as its applications, including 6 sessions: gravimetry and gravity networks, global geopotential models and vertical datum unification, local geoid/gravity modelling, satellite gravimetry, mass movements in the Earth system and solid Earth investigations.




Treatise on Geomorphology


Book Description

The changing focus and approach of geomorphic research suggests that the time is opportune for a summary of the state of discipline. The number of peer-reviewed papers published in geomorphic journals has grown steadily for more than two decades and, more importantly, the diversity of authors with respect to geographic location and disciplinary background (geography, geology, ecology, civil engineering, computer science, geographic information science, and others) has expanded dramatically. As more good minds are drawn to geomorphology, and the breadth of the peer-reviewed literature grows, an effective summary of contemporary geomorphic knowledge becomes increasingly difficult. The fourteen volumes of this Treatise on Geomorphology will provide an important reference for users from undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic. Information on the historical development of diverse topics within geomorphology provides context for ongoing research; discussion of research strategies, equipment, and field methods, laboratory experiments, and numerical simulations reflect the multiple approaches to understanding Earth’s surfaces; and summaries of outstanding research questions highlight future challenges and suggest productive new avenues for research. Our future ability to adapt to geomorphic changes in the critical zone very much hinges upon how well landform scientists comprehend the dynamics of Earth’s diverse surfaces. This Treatise on Geomorphology provides a useful synthesis of the state of the discipline, as well as highlighting productive research directions, that Educators and students/researchers will find useful. Geomorphology has advanced greatly in the last 10 years to become a very interdisciplinary field. Undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic will find the answers they need in this broad reference work which has been designed and written to accommodate their diverse backgrounds and levels of understanding Editor-in-Chief, Prof. J. F. Shroder of the University of Nebraska at Omaha, is past president of the QG&G section of the Geological Society of America and present Trustee of the GSA Foundation, while being well respected in the geomorphology research community and having won numerous awards in the field. A host of noted international geomorphologists have contributed state-of-the-art chapters to the work. Readers can be guaranteed that every chapter in this extensive work has been critically reviewed for consistency and accuracy by the World expert Volume Editors and by the Editor-in-Chief himself No other reference work exists in the area of Geomorphology that offers the breadth and depth of information contained in this 14-volume masterpiece. From the foundations and history of geomorphology through to geomorphological innovations and computer modelling, and the past and future states of landform science, no "stone" has been left unturned!
