Meteorite falls

Meteorite studies

eteorites yield a wealth of information concerning Solar System origin, geochemical evolution of primitive parent objects, and irradiation histories of material in space. Since the numerous (approximately 16,000) antarctic meteorites include many of rare or unique types, current extraterrestrial materials research attention focuses on this population. Antarctic meteorites also have the potentia...

Educational Meteorite Thin Sections

Falls.

Falls in elderly persons create a tremendous individual and social burden. Of the more than 147 million injury-related emergency department visits logged each year, falls account for approximately 24%, representing the leading cause of external injury.1 Children and elderly persons comprise the largest group responsible for this percentage. Compared with children, however, older adults are 10 t...

The Broken Belt: Meteorite Concentrations

Introduction: Since the first Antarctic meteorite concentrations were discovered more than 25 years ago, many theories regarding the role of iceflow in the production of meteorite concentrations have been put forward , and most agree on the basic principles [1-3]. These models suggest that as the East Antarctic icesheet flows toward the margins of the continent, meteorites randomly located with...

Robotic Antarctic Meteorite Search Outcomes

0 Abstract: Automation of the search for and classification of Antarctic meteorites offers a unique case for early demonstration of robotics in a scenario analogous to geological exploratory missions to other planets and to the Earth’s extremes. Moreover, the discovery of new meteorite samples is of great value because meteorites are the only significant source of extraterrestrial material avai...
