Quick Reference

Particles found on Mars that shatter into fine fragments when they smash into solid rock surface. The particles form through the aggregation by electrostatic bonding of silt- to clay-sized particles. The very low surface atmospheric pressure on Mars means that martian winds drive them at much higher speeds than similar particles could attain on Earth. When they smash into solid rock surfaces, the aggregates break into fragments about 20μm in size.
