David Harland opens with a review of the robotic probes, namely the Rangers which returned television before crashing into the Moon, the Surveyors which 'soft landed' in order to investigate the nature of the surface, and the Lunar Orbiters which mapped prospective Apollo landing sites. He then outlines the historic landing by Apollo 11 in terms of what was discovered, and how over the next several missions the program was progressively geared up to enable the final three missions each to spend three days on comprehensive geological investigations. He concludes with a review of the robotic spacecraft that made remote-sensing observations of the Moon. Although aimed at the enthusiast, and can be read as an adventure in exploration, the book develops the scientific theme of lunar geology, and therefore will be of use as background reading for undergraduate students of planetary sciences. In addition, with the prospect of a resumption of human missions, it will help journalists understand what Apollo achieved after the 'flags and footprints' of the Apollo 11 landing in July1969 and will commemorate the fortieth anniversary of that momentous event. Highlighted as a 'Commemorative Edition' on the cover, this second edition has a new foreword by one of the original astronauts and a short extra section at the end previewing the prospect of a renewal of human exploration of the Moon. It will include new extra high quality graphics which are only now available and 32 pages of colour illustrations. From the reviews of the first edition - 'A detailed guide to what the astronauts did during their stays on the lunar surface. Walk(s) the reader through the prospecting excursions and then incorporate(s) decades of subsequent analysis to put the explorations of dust, rocks, craters, and rilles into geologic context.' SKY & TELESCOPE 'EXPLORING THE MOON is very well illustrated&#8230;All aficionados of the Apollo program will find much to appreciate in [this book]. '&#8230;this is an interesting account of one of the most extraordinary decades in history&#8230;a very different book. David Harland probably knows more about the nuts and bolts of the Russian and American space programs than any other author and it shows.&#8221;LUNAR & PLANETARY INFORMATION BULLETIN

The intent of this book is to set the modern foundations of the theory of generalized curvature measures. This subject has a long history, beginning with J. Steiner (1850), H. Weyl (1939), H. Federer (1959), P. Wintgen (1982), and continues today with young and brilliant mathematicians. In the last decades, a renewal of interest in mathematics as well as computer science has arisen (finding new applications in computer graphics, medical imaging, computational geometry, visualization ...). Following a historical and didactic approach, the book introduces the mathematical background of the subject, beginning with curves and surfaces, going on with convex subsets, smooth submanifolds, subsets of positive reach, polyhedra and triangulations, and ending with surface reconstruction. We focus on the theory of normal cycle, which allows to compute and approximate curvature measures of a large class of smooth or discrete objects of the Euclidean space. We give explicit computations when the object is a 2 or 3 dimensional polyhedron. This book can serve as a textbook to any mathematician or computer scientist, engineer or researcher who is interested in the theory of curvature measures.
