This fascinating book is the work of scientist, author and artist, William K. Hartmann. What this item is, really, is a travelogue about the planet Mars! Going interesting location by interesting location, the book takes the reader across the face of Mars, and through Martian history. Along the way, the reader is treated to *many* colorful pictures and maps. This is a great book, probably the best one that I have seen on the planet Mars! I loved the way that the book is organized; somehow the author succeeds in taking his narrative location by location, and yet having it form a coherent and very informative explanation of what Mars is like now, and how it came to be that way. Also, the fact that it was published in 2003 means that it is entirely up-to-date, with information gathered by the Viking probes, the Hubble space telescope, and the Mars Global Surveyor. Overall, I found this to be a great book and a wonderful resource. If you are interested in the planet Mars, then you really must get this book! I give it my highest recommendations.
