The fact that dust will be a troublesome issue when it comes to a proposed lunar base was raised not too long ago on the Internet but an article in the March 2006 issue of Astronomy magazine brings to light additional facts that make the prospects of colonies on the Moon and Mars even more dicey than they already are. Dust may be a very serious obstacle, especially Martian dust which is most likely highly oxidative and toxic. Lunar dust is mostly silicon and silicosis is a potentially fatal condition.

That would require excellent containment and filters, a limit on the outdoor move by the inhabitants, and serious decontamination process which would involve costly use of water and ressources.

But there are places just as dangerous on earth where people work daily. And silicosis is not something that you can get from a short term exposition, there has to be a buildup of the micro fibers and particles into the lungs.

Just another technological hurdle, but might warrant a larger use of remote control of robots from the base (as opposed from Earth) which would render them MUCH more effective (realtime vs replay time)

Gee, you mean filtering high pressure air in a closed airlock wouldn't be sufficiently effective to remove most airborne particles? Scrub skin thoroughly after extensive suit contact, and yes, periodic cleaning. This isn't a game breaker, just another thing on the checklist.

You're talking about a problem solvable with a shop vac and hand soap... We do the samething here on Earth when we're done fabricating steel assemblies and we're covered in reactive(subject to corrosion) and extremely fine particulate metal dust.

I'm not impressed by this one.

Read the article.

Dust inhalation goes without saying, though I didn't realize the nature of the dust was that abusive on the equipment or people...
