text: Sometimes landforms are created when objects collide with planets. The "Face" could have been formed when a meteor crashed into Mars. Only this time the crash did not create a crater, but instead a protruding object that over the years got rounded out by storms. Evidence does not suggest that every single meteor strike causes a crater. The reason that craters are an effect on Earth may be due to Earth's atmosphere or it's magnetic field. This may just be the first time NASA has ever seen a mound created by a meteor strike. There could be more out in the universe that NASA hasn't observed yet.
