This book gives a new insight of Mars by adopting an original outline based on history rather than on subtopic (atmosphere, surface, interior). It focuses on the past and present evolution of Mars and also incorporates all the recent results from the space missions of Mars Express, Spirit and Opportunity. This book goes to the heart of current planetological research, and illustrates it with many beautiful images. The authors describe the magnificent scenery on Mars. The authors introduce a new world and reveal the workings of the planet Mars, and they describe current research to prepare for future missions to Mars.
