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
The planet Mars has been a subject of wonder for millennia, as attested by its place in mythology, by later speculation about its canals, and by the scientific and public excitement over the Viking mission. Although the scientific literature about the planet is voluminous, no comprehensive treatment of the results of modern spacecraft exploration has yet been made available. This volume fills that gap by providing a summary of what is presently known about Mars and identifying many puzzles such as polar cap variance, occurrence of dust storms, and the possible location of water. The introductory chapter cites questions, controversies, and milestones in the study of Mars, and also includes an annotated book list, basic data about the planet, and a guide to Martian seasons. A chapter on telescopic observation credits the contributions made by many amateurs that have advanced our knowledge of variations observed on Mars. A chapter on spacecraft exploration, by an American and a Russian author who have participated in all Mars missions, includes a revelation of an additional Soviet attempt. Twenty-nine technical articles cover geophysics; bedrock geology; surface; atmosphere; exosphere and magnetic field; and climate history. Two chapters address the search for life on Mars; three concluding chapters consider the Martian satellites. An indispensable reference for scientists, Mars will also serve as a complete sourcebook for serious amateur astronomers.

Book Description
"On a camping trip in rural Minnesota, the narrator encounters a curious creature, partly humanoid but with wings on his back; smaller wings in the front of his body that function apparently as clothing as well as sensory organs; an extra pair of limbs around his mid-section; a huge head with huge eyes and a vertical mouth. It immediately began to communicate with the camper, seeming to understand the camper's spoken words but addressing him telepathically. He is amiable and professorial in demeanor and proceeds to explain society on the Moon, as well as on Mars, which has been colonized by the Lunarians. The import of the book is clearly utopian, with detailed accounts (including measurements in some cases) about various aspects (economic, agricultural, sociological, biological, technological) of the society"--Robert Eldridge, bookseller
