Moon Dust Threat?

Maybe they can use some sort of high pressure air hose to blow the dust

Why not stand outside and let the vacuum suck it off?

Actually a moonsuit that's well enough coated with a layer of Po-210
should help with the anti-electrostatic situation of getting rid of
that pesky moon dust. Otherwise a teraVolt of a reverse polarity
charge before coming inside might be sufficient.

Yeah, and what is the current phase?

I wouldn't be at all surprised if what the come up with is some sort of
fairly cheap over-suit that covers the actual suit, and you dispose of
after a few EVAs.
Say something made out of woven glass fiber to prevent degradation or
boil-off in vacuum and hard UV.

Well, the original suits used lunar overshoes, I don't see any reason why a
lunar suit couldn't have the equivalent of a Tyvek oversuit that covers
everything except the helmet and gloves. With voice operated controls, you
can cover nearly the whole suit.

Something like a sticky-tape lint rod could be used on the parts of the suit
that aren't disposable every EVA, with a thorough cleaning during periodic
maintenance. If you have a dozen people regularly participating in lunar
EVAs, then you might very well need one person full time on suit
maintenance.

"Hot As Hell". :-D

Man...watching her makes me drool like Homer looking at a donut...

It's just so cool that she can give the writing staff forensic tips, just
like the guy who plays McGee can give them computer tips.

You know, it's almost poetic how you managed to cram so much complete
utter and total ******** into one sentence.

He has a lot of practice. What separates him from the usual crank is he
doesn't use as many CAPITAL LETTERS.

I'm glad somebody finally got that joke. :-)

The Russians use a semi-disposable approach to their suits; you do so
many (was it five?) EVA's with them and then toss them overboard, like
the one that was turned into a satellite fairly recently.
On the lunar suits, there may be enough wear over time where the suit
proper wears out, but you could maybe save the helmet and backpack/rear
door.

ALL YOUR CAPITAL LETTERS ARE BELONG TO US! :-P

....IIRC, the five uses limit is a bit conservative, and was actually
urged by NASA even though the Ruskies feel the suits are good for at
least 10 EVAs of at least 6 hours in length. In fact, there's been
some discussions about not immediately dumping suits that are just out
of "warranty", and keeping at least three around for emergencies.

That's odd, as to mention the best available truth gets those Usenet
lights turned off, and those exit doors slammed shut.

Our physically dark moon is in fact highly electrostatic charged,
whereas at times it could be charged to the potential of being
teraVolts different than Earth. Of course a valid science platform of
instruments as easily located within the moon's L1 would tell us
exactly how many teraVolts and of what sort of polarity we're talking
about.
