Is Mars the Source of the Dust?

Mars is thought to be the source of this dust, that little grains of stuff are leaving mars and basically polluting our solar system. They don't yet have an understanding for life how the dust is leaving mars, but it has a weaker atmosphere and a weaker gravity and e dust storms. So it could be comets, it's be asteroids, but maybe not so much. Could it be earth also being a limesy? Or maybe some of the other planets. Probably the answer is a little bit of all of them.
