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.

Available in PDF, EPUB and Kindle. Book excerpt: This fascinating book reviews the progress made in Mercury studies since the flybys by Mariner 10 in 1974-75. Thus far, it is the only book on Mercury which balances a wide range of Earth-based observations, made under difficult conditions, with the only available space-based data. The text is based on continued research using the Mariner 10 archive, on observations from Earth, and on increasingly realistic models of this mysterious planet’s interior evolution.

This book was released on 2014-10-20 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mariner-10 flybys of Mercury in 1974 and 1975 resulted in the discovery of a planetary magnetic field and an active magnetosphere similar to that of Earth. Based upon the small size of the planet, Mercury's interior was expected to have cooled and solidified long ago. The presence of an intrinsic magnetic field, however, implied an internal dynamo in a fluid core, posing fundamental, unresolved issues concerning the origin, composition, and thermal history of Mercury. The Mariner-10 spacecraft also detected intense particle bursts and magnetic field disturbances, indicating that magnetospheric substorms occur at Mercury. The Mariner-10 images revealed a number of surface features unique to Mercury, including large-scale thrust faults apparently associated with crustal compression as the planet cooled and contracted. Follow-on missions to Mercury were studied in the late 1970's, but deferred because of perceived difficulties in spacecraft propulsion and thermal engineering requirements as they were understood at the time. Within the past few years, it has become apparent that a moderate-cost mission to Mercury can provide the particles and fields measurements and planetological observations necessary to yield major advances in our understanding of Mercury and its magnetosphere. Mercury Orbiter (MeO) as described in this report is such a mission. It involves dual, spin stabilized spacecraft launched by a single Titan-IV Centaur vehicle, a 4-5 year gravity-assist trajectory, and a nominal one Earth-year-duration mission at Mercury. This report presents the results of the Mercury Orbiter Science Working Team (MeO SWT) which held three workshops in 1988/1989 under the auspices of the Space Physics and Planetary Exploration Divisions of NASA Headquarters. Spacecraft engineering and mission design studies at the Jet Propulsion Laboratory were conducted in parallel with this effort and are detailed elsewhere. The findings of the engineering study, summarized in this report, indicate that spin-stabilized spacecraft carrying comprehensive particles and fields experiments and key planetology instruments in highly elliptical orbits can survive and function in Mercury orbit without costly sun-shields and active cooling systems.
