The Martian Meteorite

Mars has been the target for increasing numbers of probes all designed to add to our knowledge of our neighbouring planet. Roughly 16 million years ago a huge meteor collided with Mars. Its impact was so great that it dislodged some of the Martian surface sending it back out into space. Some of this debris collided with Earth about 11 thousand years ago and a piece called MIS 03346 was recently discovered in Antarctica.
