It's 1984, and you're a member of a meteorite-hunting party. You're searching a glacier in Antarctica. Brrrr! It's cold, but you're determined to find a meteorite, a rock from outer space. Suddenly, you see a dark rock on the ice. It looks like other meteorites you've found. When you get home, you put the rock in a drawer. About ten years later, you ask some scientists to examine it.
