The Field’s team consisting of University of Chicago graduate student Jennika Greer and Robert A. Pritzker Associate Curator Philipp Heck used scanning electron microscopy with X-ray spectroscopy and Raman spectroscopy to classify the rock as a very weakly shocked H4 chondrite. Out of about 60,000 confirmed meteorites, only about 0.1 percent are H4 chondrite falls. The meteorite is now officially named after Hamburg, Michigan.
A bright fireball streaked across the sky on January 16, 2018 near Detroit. The shockwave through the air caused a magnitude 2.0 earthquake in the area. Meteorite hunter Robert Ward used a strewn field map generated through Doppler radar data from NASA collaborator Marc Fries to search for meteorites. He found several pieces, and donated one to the Field. The connection to Robert Ward is thanks to long-time Field Museum supporter and private meteorite collector Terry Boudreaux. Robert A.

No, it’s not a sci-fi movie, but rather the unique Swedish fossil meteorite Oesterplana 065 which is the subject of a paper published last week in Meteoritics & Planetary Science by Postdoctoral Scholar Surya Rout (now at the University of Bern, Switzerland), Robert A. Pritzker Associate Curator for Meteoritics and Polar Studies Philipp Heck, and Field Museum Research Associate and Professor of Geology Birger Schmitz (Lund University of Sweden).
Resident Ph.D. Student Jennika Greer (Univ. of Chicago/Geophysical Sciences) has been selected to receive the McKay Award,* which honors the best student oral presentation at the Meteoritical Society Annual Meeting. This is particularly impressive, since this was her first oral presentation at a major scientific meeting. Jennika’s project focused on the analysis of a lunar sample to study the effects of space weathering, which affects airless bodies such as the Moon and asteroids.
You’ll recall the big news about the Museum’s acquisition of rare fossil meteorites a few years ago. These rocks from space fell into an ancient sea about 470 million years ago, and after three years at the Museum, continue to yield new information at the hands of Pritzker Associate Curator Philipp Heck and colleagues.
