Earth hit by hundreds of meteorites originating from only 5 craters on Mars

The debris breaks free of Mars' gravitational pull and enters the orbit around the sun, and some of them eventually fall to Earth. “Now, we can group these meteorites by their shared history and then their location on the surface prior to coming to Earth,” Chris Herd, a study co-author, professor of earth and atmospheric sciences, and curator of UA’s Meteorite Collection said. Hundreds of such rocks have been discovered in the last few years.
