"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). 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."--Publisher's description.
