The Encyclopedia of Lunar Science includes the latest topical data, definitions, and explanations of the many and varied facets of lunar science. This will be a very useful reference work for a broad audience, not limited to the professional lunar scientist: general astronomers, researchers, theoreticians, practitioners, graduate students, undergraduate students, and astrophysicists as well as geologists and engineers. The title will include all current areas of lunar science, with the topic entries being established tertiary literature. The work will be a readable but technically suitable to most advanced undergraduate and graduate students. The articles will include topics of varying technical levels so that the top scientists of the field will find this work a benefit as well the graduate students and the budding lunar scientist. A few examples of topic areas are as follows: Astronomers and Astronauts, Basaltic Volcanism, Lunar Chemistry, Time and Motion Coordinates, Cosmic Weathering through Meteoritic Impact, Environment, Geology, Geologic History, Impacts and Impact Processes, Lunar Surface Processes, Origin and Evolution Theories, Regolith, Stratigraphy, Tectonic Activity, Topography, Weathering through ionizing radiation from the solar wind, solar flares, and cosmic rays.
