Hunting meteorites
Team members in the Antarctic Search for Meteorites (ANSMET) program traverse the polar ice sheets in search of fragments of rock that have fallen from the sky. Since the program began almost four decades ago, the Antarctic missions have brought back more than 20,000 meteorites, and the program has loaned thousands of samples to researchers all over the world who are trying to make discoveries about the evolution of planets and stars.
