ABSTRACT
The article reports that there are pieces of Mars on Earth. It also presents several clues that presents information on how asteroids are the source of most meteorites. Meteorites must have struck Mars many times, sending rocks out into space. Rocks larger than a couple of inches in diameter generally make it through the atmosphere and hit the ground. A huge impact 65 million years ago damaged the environment so much that dinosaurs and many other creatures became extinct. Most meteorites are so small that they do little damage. Astroners believe that most meteorites come from the asteroid belt, a region of space between the orbits of Mars and Jupiter.
