On April 9, 2013 the Field Museum's Robert A. Pritzker Center for Meteoritics and Polar Studies has obtained more than 2.2 pounds and 234 pieces of the Chelyabinsk meteorite through a donation of meteorite collector Terry Boudreaux. Pieces of the meteorite are available for scientific research. Research on that meteorite will help us better understand the history of the solar system in particular its collisional history. The donation was extensively covered by the media. The Chelyabinsk meteorites will be on public display at the Field Museum starting Wednesday afternoon, April 9, 2013.
The first scientific paper describing the almost local meteorite Mifflin that fell on April 14, 2010 in southwestern Wisconsin got published this week in the peer-reviewed journal Meteoritics & Planetary Science. The Robert A. Pritzker Assistant Curator for Meteoritics and Polar StudiesPhilipp Heck is a member of the international consortium who studied the space rock and co-author of the study.
The Field Museum has acquired six pieces of an extremely important Martian meteorite that was hurled into space about 700,000 years ago when Mars collided with an asteroid.
From January 25-27, 2013 the Annual Presolar Grains Workshop was held in Chicago. At this informal gathering cosmochemists and astrophysicists met and talked about how the study of presolar grains can help improve our understanding of how stars work.
Robert A. Pritzker Assistant Curator of Meteoritics and Polar Studies Dr. Philipp R. Heck is co-author on a paper in the journal Science on the first results of the rare meteorite, Sutter’s Mill. On April 22 a very fast-moving fireball was observed over large parts of California and Nevada. Equivalent to four kilotons of TNT, the fireball was photographed, and recorded by video and by weather Doppler-radars. The photographs and videos helped to trace back its orbit to the far reaches of the outer part of the asteroid belt. The Sutter’s Mill meteorite was scrutinized by almost the entire arsenal of observational and analytical state-of-the-art tools available to scientists today.

On September 24, Collections & Research Committee Member and private meteorite collector Terry Boudreaux donated and loaned specimens of a freshly fallen meteorite to the Museum’s Robert A. Pritzker Center for Meteoritics and Polar Studies. The meteorite produced a fireball associated with a sonic boom before it hit the ground near Battle Mountain, NV on August 23. The meteorite is tentatively classified as an ordinary chondrite of type L6.
The Robert A. Pritzker Center for Meteoritics and Polar Studies hosts five high-school students and three undergraduate students students this summer. They receive a unique hands-on education with meteorite-related laboratory work and collections management projects. On our website and on our Facebook page we will feature brief presentations of them, their projects and experience at the RAPC.
The Field Museum will receive a high-quality meteorite from a fireball that exploded over California and Nevada last month. The 4.6-billion-year-old meteorite, donated by private collector Terry Boudreaux, is extremely rare and valuable to science. It weighs about one-third of an ounce (10 grams) and has been tentatively classified as carbonaceous chondrite.
