A 40-pound meteorite falls to Earth, landing in a cornfield in Nigeria. In the 1990s it was determined that the meteorite had originated on Mars and was likely propelled into space when an asteroid or comet struck the planet millions of years earlier. (It remains the largest Mars meteorite to have been found on Earth.)
