Those of us who were around during the early Apollo days know well about the "Gold Dust Theory," that cost NASA beaucoup dollars. And the electrostatic fluffiness of the lunar soil was not a problem to landing on the Moon, but may contributed to the dust that was observed to cling to the astronauts' suits, as well as to the "rock boxes" such that they all leaked. However, the fine-grain nature (50 wt% = less than 50 microns) of the lunar soil, in the presence of the 1/6 th gravity of the Moon, with the potential for extensive beneficiation of lunar soil has the 'EPA' and astronomers upset. They envision huge clouds of dust flying around the Moon, covering telescopes and solar cells. In addition, the large glass contents (up to 100%) of lunar soil makes the abrasive properties of the dust a great concern for any moving parts. However, a possible solution to many of these fears involves use of the magnetic properties of the lunar soil and results of recent studies of the Lunar Soil Characterization Consortium (LSCC).
