This book was released on 2015-03-02 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SpringerBrief details the MESSENGER Mission, the findings of which present challenges to widely held conventional views and remaining mysteries surrounding the planet. The work answers the question of why Mercury is so dense, and the implications from geochemical data on its planetary formation. It summarizes imaging and compositional data from the terrestrial planet surface processes and explains the geologic history of Mercury. It also discusses the lack of southern hemisphere coverage. Our understanding of the planet Mercury has been in a transitional phase over the decades since Mariner 10. The influx of new data from the NASA MESSENGER Mission since it was inserted into the orbit of Mercury in March of 2011 has greatly accelerated that shift. The combined compositional data of relatively high volatiles (S, K), relatively low refractories (Al, Ca), and low crustal iron, combined with an active, partially molten iron rich core, has major implications for Mercury and Solar System formation. From a scientist at NASA Goddard Space Flight Center, this presents a comprehensive overview of the discoveries from the ten-year MESSENGER mission.

Download or read book Planetary Volcanism Across the Solar System written by Tracy K. P. Gregg and published by Elsevier. This book was released on 2021-12-08 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planetary Volcanism across the Solar System compares and contrasts the vast array of planetary bodies in the Solar System, including Earth. The wealth of spacecraft data for almost all major solid-surface bodies in the Solar System indicate that volcanism has been a dominant mechanism in shaping the landscapes of these bodies. The book addresses key questions surrounding our understanding of planetary volcanism, such as how to integrate the data into a coherent view of how volcanic activity arises, how this mechanism shapes planets, which volcanic landforms are ubiquitous throughout the Solar System, and which are unique. By placing a singular emphasis on comparing volcanic processes and landforms on all relevant Solar System bodies, and with the explicit objective of providing a systems-level understanding of this widespread phenomenon, users will find an up-to-date, accessible and comprehensive discussion of the major volcanic processes and landforms that shape and drive the evolution of planets, moons and smaller bodies. Includes an introduction placing the book in the context of the larger Comparative Planetology series Compares volcanic processes and landforms on all relevant Solar System bodies, providing a systems-level understanding of this widespread phenomenon Offers a thorough examination of the major volcanic processes and landforms that shape and drive the evolution of planets, moons and smaller bodies Includes information from new mission data and discoveries in recent years Features over 100 color illustrations and charts to more clearly convey concepts Offers additional online content, including figures, animations, video, and other multimedia content such as interviews with contributing authors
Download or read book Exploring Mercury written by Robert G. Strom and published by Springer Science & Business Media. This book was released on 2003-07-15 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strom: Mercury How did Mercury get such an enormous iron core? Why is its tectonic framework so different from any other planet or satellite? What is its crystal composition? Why is the crust so depleted in iron when the interior is so rich in that element? What are the polar deposits? Where do the elements in the exosphere come from? Mercury is a planet shrouded in mystery. Only 45 percent of its surface has been seen in any detail, and that was from the Mariner 10 flyby in 1974. Yet what is known only makes the planet more fascinating. New Earth-based observations have shed light on surface and exosphere compositions, and re-evaluations of the Mariner 10 data, using modern image processing techniques, show evidence for volcanic flow fronts, pyroclastics and other volcanic phenomena not seen before. This ground-breaking book not only chronicles what has been discovered, but looks ahead to what has yet to emerge. An accompanying CD contains all the best Mariner 10 images, including the data for each image, photomosaics and maps.

Download or read book Vision and Voyages for Planetary Science in the Decade 2013 2022 written by National Research Council and published by National Academies Press. This book was released on 2012-01-30 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, planetary science has seen a tremendous growth in new knowledge. Deposits of water ice exist at the Moon's poles. Discoveries on the surface of Mars point to an early warm wet climate, and perhaps conditions under which life could have emerged. Liquid methane rain falls on Saturn's moon Titan, creating rivers, lakes, and geologic landscapes with uncanny resemblances to Earth's. Vision and Voyages for Planetary Science in the Decade 2013-2022 surveys the current state of knowledge of the solar system and recommends a suite of planetary science flagship missions for the decade 2013-2022 that could provide a steady stream of important new discoveries about the solar system. Research priorities defined in the report were selected through a rigorous review that included input from five expert panels. NASA's highest priority large mission should be the Mars Astrobiology Explorer Cacher (MAX-C), a mission to Mars that could help determine whether the planet ever supported life and could also help answer questions about its geologic and climatic history. Other projects should include a mission to Jupiter's icy moon Europa and its subsurface ocean, and the Uranus Orbiter and Probe mission to investigate that planet's interior structure, atmosphere, and composition. For medium-size missions, Vision and Voyages for Planetary Science in the Decade 2013-2022 recommends that NASA select two new missions to be included in its New Frontiers program, which explores the solar system with frequent, mid-size spacecraft missions. If NASA cannot stay within budget for any of these proposed flagship projects, it should focus on smaller, less expensive missions first. Vision and Voyages for Planetary Science in the Decade 2013-2022 suggests that the National Science Foundation expand its funding for existing laboratories and establish new facilities as needed. It also recommends that the program enlist the participation of international partners. This report is a vital resource for government agencies supporting space science, the planetary science community, and the public.
Download or read book Planet Mercury written by David A. Rothery and published by Springer. This book was released on 2014-11-13 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new and detailed picture of Mercury is emerging thanks to NASA’s MESSENGER mission that spent four years in orbit about the Sun’s innermost planet. Comprehensively illustrated by close-up images and other data, the author describes Mercury’s landscapes from a geological perspective: from sublimation hollows, to volcanic vents, to lava plains, to giant thrust faults. He considers what its giant core, internal structure and weird composition have to tell us about the formation and evolution of a planet so close to the Sun. This is of special significance in view of the discovery of so many exoplanets in similarly close orbits about their stars. Mercury generates its own magnetic field, like the Earth (but unlike Venus, Mars and the Moon), and the interplay between Mercury’s and the Sun’s magnetic field affects many processes on its surface and in the rich and diverse exosphere of neutral and charged particles surrounding the planet. There is much about Mercury that we still don’t understand. Accessible to the amateur, but also a handy state-of-the-art digest for students and researchers, the book shows how our knowledge of Mercury developed over the past century of ground-based, fly-by and orbital observations, and looks ahead at the mysteries remaining for future missions to explore.
Download or read book Investigation of the Interior of Mercury Through the Study of Its Gravity Topography and Tidal Response written by Sebastiano Padovan and published by . This book was released on 2015 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the goal of furthering our understanding of the interior structure of Mercury, this work tries to answer the following two questions. What can the response of the planet to solar tides reveal about the interior structure? What is the thickness of the crust and what are the implications for the interior? By comparing the models developed here for the tidal response of Mercury with the response measured by the MErcury Surface Space ENvironment GEochemistry and Ranging spacecraft (MESSENGER), the rheology of the mantle of the innermost planet is investigated. The measured tidal deformation indicates that, unless the rigidity of mantle materials is unexpectedly high, the mantle is relatively cold. Geochemical arguments based on the composition of the surface of Mercury as measured by MESSENGER have been used to put forward the hypothesis of the existence of a solid FeS layer at the bottom of the mantle. The tidal modeling indicates that the presence of the FeS layer is unlikely. To further constrain the interior structure of Mercury the thickness of the crust is calculated by computing geoid-to-topography ratios over the surface of the planet. The inferred crustal thickness, $35\pm18$ km, has three interesting implications. First, this relatively thin crust allows for the possibility that basin-forming events excavated mantle material from Mercury's mantle. If this material is still exposed on the surface it can potentially be observed by instruments onboard MESSENGER and future missions at Mercury. Second, the volume of silicate materials present in the crust of Mercury represents about 10\% of the total silicate materials in the planet, the largest value among the terrestrial planets. This implies that Mercury had the highest efficiency of crustal production. Finally, by combining the estimate of the crustal thickness with the measured abundances of heat-producing elements on the surface of Mercury a lower bound can be placed on the amount of heat production in the mantle at a time following the accretion and differentiation of the planet, approximately 4.45 Ga ago. This information is useful for future models of the thermochemical evolution of the innermost planet.
