Paolo Ulivi and David Harland provide in Robotic exploration of the solar system a detailed history of unmanned missions of exploration of our solar system. The subject is treated from an engineering and scientific standpoint. Technical descriptions of the spacecraft, of their mission designs and of instrumentations are provided. Scientific results are discussed in considerable depth, together with details of mission management.The project will deliver four volumes totaling over 2,000 pages that will provide comprehensive coverage of the topic with thousands of references to the professional literature that should make it the 'first port of call' for people seeking information on the topic. The books will cover missions from the 1950s until the present day, and some of the latest missions and their results will appear in a popular science book for the first time.
