Where do meteorites of different types come from? Astronomers trace the impact orbit of observed meteorite falls to several previously unidentified source regions in the asteroid belt.
“This has been a decade-long detective story, with each recorded meteorite fall providing a new clue,” said Peter Jenniskens of the SETI Institute and NASA Ames Research Center. “We now have the first outlines of a geologic map of the asteroid belt.”
