The numbers of known lunar meteorites have been increasing rapidly – as of May 2009 there are close to 60 meteorites that have been classified as pieces of the Moon. 19 of these are from Antarctica, and the others are from hot desert localities in Africa, Australia, and the Middle East. The total mass of recognized lunar meteorites is over 50 kg, as compared to the 21.5, 34.4, 42.3, 77.3, 95.7, and 110.5 kg of rock brought back from the Moon by Apollo 11, 12, 14, 15, 16 and 17, respectively. Because of the mass, diversity and number of lunar meteorites in world collections, a Lunar Meteorite Compendium was initiated by the Astromaterials Curation Office at NASA Johnson Space Center. This is justified for several reasons: 1) the popularity the Mars Meteorite Compendium (MMC) provided precedence for initiating a project of this scale; 2) as our community becomes increasingly geared toward sample return missions, the need for succinct presentation of information about sample collections rises; and 3) a compendium can serve the reader as a springboard into the extensive peer reviewed literature. This compendium includes the following information where possible and available: a) collection and macroscopic details (maps and images), b) curation details (images, sketches), c) basic petrography, mineralogy and petrology (diagrams, tables, and thin section or hand sample images), d) basic major, trace and isotopic geochemistry, e) chronologic information and studies, and f) comparisons to Apollo and Luna samples, as well as any relevant spacecraft data.
