Curators at the Department of Mineral Sciences at the National Museum of Natural History classify each representative chip of meteorite sent by NASA. Results and descriptions are published in the Antarctic Meteorite Newsletter, issued twice a year by NASA’s Johnson Space Center. Scientists are invited to request samples for their scientific investigations by submitting formal requests to the Meteorite Working Group (MWG). The MWG is composed of meteorite researchers including one permanent representative each from NASA, the Smithsonian Institution, and ANSMET, who offer expert advice on distribution of samples both small and unique. Since 1976, over 350 investigators representing 20+ nations have received more than 14,000 samples of Antarctic meteorites. The average number of requests received annually is approximately 75, for an average of nearly 600 samples.
