Mars dust is full of perchlorates, silica, and heavy metals
The panel included toxicologists, volcanologists, geologists, and habitat designers, and NASA asked them to set a limit before anyone lands. The Apollo missions showed that dust is a real problem. The dust the 12 moonwalkers tracked inside was fine, sharp, and glassy.
