Meteorites that fall in Antarctica typically become embedded in the ice sheet. Due to ice flow and surface processes, a small fraction of all meteorites in the ice resurface in some of the continent’s blue ice areas. The contrasting blue ice makes it easy to detect and collect meteorites during Antarctic field work missions.
Meteorites are too small to detect from space, but with indirect satellite measurements (temperature, speed of the ice flow, the surface slope, and the way the ice reflects radar signals) and machine learning, we can predict where meteorites concentrate at the surface.

Our research was possible thanks to (the contributions to) the Meteoritical Bulletin Database. Results will improve with additional data, on both succesful and unsuccesful meteorite searching campaigns. Sharing this data is encouraged.
