A complete overview of the observation/exploration/colonization of Mars. From the early years, I was surprise to saw that we've been observing Mars for so long in modern space exploration, to today and even a brief part about what's next. All very well explain, good amount of details, and beautiful pictures. This is a very specific book on a very specific subject, for a very specific kind of reader. But it's very well made, clear and well organized. So if Mars or space exploration in general interest you this should probably be a good one for you! Good job!
