Book Description
This book explores the once popular idea of 'Flexible Path' in terms of Mars, a strategy that would focus on a manned orbital mission to Mars's moons rather than the more risky, expensive and time-consuming trip to land humans on the Martian surface. While currently still not the most popular idea, this mission would take advantage of the operational, scientific and engineering lessons to be learned from going to Mars's moons first. Unlike a trip to the planet's surface, an orbital mission avoids the dangers of the deep gravity well of Mars and a very long stay on the surface. This is analogous to Apollo 8 and 10, which preceded the landing on the Moon of Apollo 11. Furthermore, a Mars orbital mission could be achieved at least five years, possibly 10 before a landing mission. Nor would an orbital mission require all of the extra vehicles, equipment and supplies needed for a landing and a stay on the planet for over a year. The cost difference between the two types of missions is in the order of tens of billions of dollars. An orbital mission to Deimos and Phobos would provide an early opportunity to acquire scientific knowledge of the moons and Mars as well, since some of the regolith is presumed to be soil ejected from Mars. It may also offer the opportunity to deploy scientific instruments on the moons which would aid subsequent missions. It would provide early operational experience in the Mars environment without the risk of a landing. The author convincingly argues this experience would enhance the probability of a safe and successful Mars landing by NASA at a later date, and lays out the best way to approach an orbital mission in great detail. Combining path-breaking science with achievable goals on a fast timetable, this approach is the best of both worlds--and our best path to reaching Mars safely in the future.

Book Description
Scientists have collected a wealth of physical and chemical data for the Sun, planets, and small bodies in our solar system, but until now this information has been scattered throughout the technical literature. The Planetary Scientist's Companion solves this problem, providing for the first time a single, extensive reference for the interdisciplinary fields of planetary science and cosmochemistry. The book begins with a summary of frequently used physical and chemical constants, unit conversion factors, properties of some compounds and minerals, thermodynamic data, partition coefficients, and useful formulas. This is followed by an overview of the solar system, including comparative data for the planets and their satellites and abundances of the elements. Much of the book is devoted to a series of chapters describing in turn the Sun, each of the planets, and the groups of small bodies (asteroids, comets, meteorites, and Kuiper Belt and Centaur objects). Each chapter includes an introduction, followed by tables of physical and chemical properties compiled from many sources, including data on planetary atmospheres, surfaces, and interiors. The book concludes with data on nearby stars, the interstellar medium, and recently discovered brown dwarfs and possible extrasolar planets, followed by a glossary. A unique and practical resource for anyone interested in contemporary planetary science and cosmochemistry, this volume is likely to be an essential tool in future research.
