In the wake of a flood of new data and images from several exploratory missions, fascination with Mars has become even more intense than it was when Percival Lowell believed he had observed canals constructed by live Martians. While we know that these never existed, we do have evidence that Mars once had rivers, shallow lakes, glaciers, huge active volcanoes, and intense flooding. In this book Peter Cattermole, a geologist who has been studying the planet for many years, captures the sense of continuing excitement about Mars and its history. He builds his story on the foundations of his earlier book, Mars: The Story of the Red Planet (Chapman Hall, 1992) At that time, although a large data archive and an overall picture of Mars' geological development existed, relatively little was known of the planet's volatile history, of short-term changes in climate and weather, and of the possible existence of large bodies of surfaced water. The discovery of what might be organic remains in an Antartic meteorite from Mars was completely unanticipated as well. Since then, new studies from the Mariner 9 and the Viking probes have appeared, new Earth-based spectroscopic measurements and oservations from the Hubble space telescope have been made, the meteorite has been analyzed (inconclusively) and, of course, Mars Pathfinder and Mars Global Surveyor have arrived. An immense amount of visual, geochemical, and physical data concerning the rocks, landscape, and weather is now available. The new book draws on this wealth of new information, providing a clear account of current scientific understanding of the Red Planet. Note this book was published in 2001 and reflects the state of knowledge about Mars before recent explorations such as that being undertaken by the Curiosity rover Non sono state trovate descrizioni di biblioteche |

Nonetheless, this is a comprehensive summary of what we knew up to 2001, and as such will be a good basis for future study. (Some later impressions do have an additional page added summarising then-recent findings about recent surface water.) But as the bulk of the content derives from remote sensing studies, the time will come when this book will be considered a foundation text only but lacking in more up-to-date discoveries. That time will only come about once teams of experts have spent considerable time with boots on the ground (or regolith) and their findings have been reviewed, published, argued over and thoroughly absorbed. Come back in a hundred years or so.
