Download or read book Rosetta written by C. T. Russell and published by . This book was released on 2007-05 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comets consist of the most primitive, i.e. unprocessed, material in the solar system. To understand the earliest epoch of solar system formation, we must investigate the nature of this material. Much of what we know of comets presently comes from remote sensing using Earth-based telescopes, plus a few brief flybys that have added only a few hours of in-situ observation. The Rosetta mission is poised to make a dramatic advance in our understanding of comets by matching trajectories with comet 67P/Churyumov-Gerasimenko, orbiting it, and setting a lander on its surface. This volume describes the scientific objectives of the mission, the expected cometary environment, and the instruments that will probe the comet.
Download or read book Comets II written by M. Festou and published by University of Arizona Press. This book was released on 2004-11 with total page 780 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of comets is a field that has seen tremendous advances in recent years, far surpassing the knowledge reflected in the original Comets volume published as part of the Space Science Series in 1982. This new volume, with more than seventy contributing authors, represents the first complete overview of comet science in more than a decade and contains the most extensive collection of knowledge yet assembled in the field. Comets II situates comet science in the global context of astrophysics for the first time by beginning with a series of chapters that describe the connection between stars and planets. It continues with a presentation of the formation and evolution of planetary systems, enabling the reader to clearly see the key role played in our own solar system by the icy planetesimals that were the seeds of the giant planets and transneptunian objects. The book presents the key results obtained during the 1990s, in particular those collected during the apparition of the exceptional comets C/Hyakutake and C/Hale-Bopp in 1996-1997. The latest results obtained from the in situ exploration of comets P/Borrelly and P/Wild 2 are also discussed in detail. Each topic of is designed to be accessible to students or young researchers looking for basic, yet detailed, complete and accurate, information on comet science. With its emphasis on the origin of theories and the future of research, Comets II will enable scientists to make connections across disciplinary boundaries and will set the stage for discovery and new understanding in the coming years.
Download or read book Astromineralogy written by Thomas Henning and published by Springer Science & Business Media. This book was released on 2010-09-21 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astromineralogy deals with the science of gathering mineralogical information from the astronomical spectroscopy of asteroids, comets and dust in the circumstellar environments in general. This field has received a tremendous boost with the reliable identification of minerals by the Infrared Space Observatory. The first edition of this book, published in 2003, was the first comprehensive and coherent account of this exciting field. Data obtained in the meantime with the Spitzer Infrared Space Telescope, the stardust mission to the comet 81P / Wild 2, and with the Cassini mission, together with progress in ground-based observations and laboratory astrophysics form the basis for this updated and widely extended second edition.Beyond addressing the specialist in the field, the book is intended as a high-level but readable introduction to astromineralogy for both the nonspecialist researcher and the advanced student.

Download or read book Cometary Science written by Nicolas Thomas and published by Springer. This book was released on 2022-04-17 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a status report on where we stand today in studies of cometary nuclei and their immediate environment. The papers were derived from a Horizon 2020 project called MiARD (Multi-instrument Analysis of Rosetta Data), which was designed to use multiple datasets from the Rosetta mission to comet 67P/Churyumov-Gerasimenko to place further constraints on the properties of the nucleus of the comet and its immediate environment. The individual chapters are the result of a significant effort by leading researchers to establish clear statements on what we know from current cometary data. Based on a workshop held in 2018 at the International Space Sciences Institute, the book focuses on the nucleus itself and the relationship between the surface properties and the observed outgassing. Additionally, it makes a first critical assessment of the Rosetta dataset, establishing what would be an appropriate next step in cometary research.

Download or read book Catching Stardust written by Natalie Starkey and published by Bloomsbury Publishing. This book was released on 2018-03-08 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Astonishing' - New Scientist Icy, rocky, sometimes dusty, always mysterious – comets and asteroids are among the Solar System's very oldest inhabitants, formed within a swirling cloud of gas and dust in the area of space that eventually hosted the Sun and its planets. Locked within each of these extra-terrestrial objects is the 4.6-billion-year wisdom of Solar System events, and by studying them at close quarters using spacecraft we can coerce them into revealing their closely-guarded secrets. This offers us the chance to answer some fundamental questions about our planet and its inhabitants. Exploring comets and asteroids also allows us to shape the story of Earth's future, enabling us to protect our precious planet from the threat of a catastrophic impact from space, and maybe to even recover valuable raw materials from them. This cosmic bounty could be as useful in space as it is on Earth, providing the necessary fuel and supplies for humans as they voyage into deep space to explore more distant locations within the Solar System. Catching Stardust tells the story of these enigmatic celestial objects, revealing how scientists are using them to help understand a crucial time in our history – the birth of the Solar System, and everything contained within it.

Download or read book Exploration of Halley s Comet written by Michael Grewing and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1005 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1985/86 apparition of Halley's Comet turned out to be the most important apparition of a comet ever. It provided a worldwide science community with a wealth of exciting new discoveries, the most remarkable of which was undoubtedly the first image of a cometary nucleus. Halley's Comet is the brightest periodic comet, and the most famous of the 750 known comets. With its 76-year period, its recent appearance was truly a "once-in-a-lifetime" observational opportunity. The 1985/86 apparition was the thirtieth consecutive recorded apparition. Five apparitions ago, the English astronomer Edmond Halley discovered the periodicity of "his" comet and correctly predicted its return in 1758, a triumph for science best appreciated in the context of contemporary views, or rather fears, about comets at that time. The increasingly rapid progress in technological development is very much apparent when one compares the dominant tools for cometary research during Halley's next three apparitions: in 1835 studies were made based on drawings ofthe comet; in 1910 photographic plates were used; while in March 1986 an armada of six spacecraft from four space agencies approached the comet and carried out in situ measurements, 1 AU from the Earth. In 1910, nobody could have dreamed that this was possible, and today it is equally difficult to anticipate what scientists will be able to achieve in 2061.
Download or read book The Comet written by Jean-Pierre Bibring and published by Editions Xavier Barral. This book was released on 2019-05-21 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: A gorgeously printed portrait of a comet In 2004, following more than ten years of research, the European Space Agency decided to send the Rosetta probe to study the 67P comet Churyumov Gerasimenko, nicknamed "Tchoury." After a ten-year voyage and hundreds of millions of miles crossed through space, the probe entered the comet's orbit and stayed there for 18 months--a first in the history of space conquest. Its lander, Philae, a kind of miniature science laboratory, landed directly on Tchoury's surface to sample matter for analysis. The mission: to find some answers to the questions of the origins of the solar system and the emergence of life on Earth. Among the important data collected by the Rosetta probe were scores of incredible new photographs of the comet--presented here in an extraordinary book, a sequel of sorts to 2013's This Is Mars. The Cometis structured around the various phases of the probe's journey: leaving Earth, breaching its atmosphere and watching its lights disappear; skirting the Moon and coming close to Mars; and finally losing itself in the starry void of the cosmos and approaching the comet. Thanks to highly developed optical technology, each of these encounters yielded captivating images of the various planets in incredibly high definition; their textures and surfaces appear on the paper in vivid detail. In addition to the staggering collection of images, The Cometincludes a text by Jean-Pierre Bilbring, an astrophysicist involved with the Rosetta project, reflecting on the objectives of this mission and the accomplishment of such a technological feat for humanity. The result of an interstellar voyage, this book is a photographic dream that transports the reader into space aboard the Rosetta probe.

Award-winning space writer Peter Bond takes us behind the scenes of this historic endeavor, sharing insights from the international team of scientists and engineers who made the mission possible, describing the remarkable technology that they created, and delving into the treasure trove of scientific discoveries that followed. Recounting in vivid detail the inner workings of Rosetta, this book is a celebration of the mission that has left a lasting impact on planetary science and space exploration.
Download or read book An Introduction to Comets written by Nicolas Thomas and published by Springer Nature. This book was released on 2020-12-15 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by a leading expert on comets, this textbook is divided into seven main elements with a view to allowing advanced students to appreciate the interconnections between the different elements. The author opens with a brief introductory segment on the motivation for studying comets and the overall scope of the book. The first chapter describes fundamental aspects most usually addressed by ground-based observation. The author then looks at the basic physical phenomena in four separate chapters addressing the nucleus, the emitted gas, the emitted dust, and the solar wind interaction. Each chapter introduces the basic physics and chemistry but then new specific measurements by Rosetta instruments at comet Churyumov-Gerasimenko are brought in. A concerted effort has been made to distinguish between established fact and conjecture. Deviations and inconsistencies are brought out and their significance explained. Links to previous observations of comets Tempel 1, Wild 2, Hartley 2, Halley and others are made. The author then closes with three smaller chapters on related objects, the loss of comets, and prospects for future exploration. This textbook includes over 275 graphics and figures – most of which are original. Thorough explanations and derivations are included throughout the chapters. The text is therefore designed to support MSc. students and new PhD students in the field wanting to gain a solid overview of the state-of-the-art.
