re: Lunar Dust Buster
Yes, Lunar regolith is very complex and thus will offer a very interesting problem to resolve before we can send humans there for any length of time. Right now it seems the ionized cosmic rays radiation levels primary and the secondary radiation form them and these fines are show stopper for long term Lunar exploration. Making the Moon "a bridge to far" so to speak.
That individuals have pretended by isolating the regolith's properties we can solve the contamination problems is amusing to say the least. A hint for the experimenters: this stuff is found in a hard vacuum.
