Haven't had a "here comes the science" headline in awhile.
And I guess if someone doesn't fix this one we still won't, eh?

Jeez.....imagine what this stuff would do.......

Too bad it's largely composed of aluminum and titanium. That might be a problem for electronics.

I rather doubt it's conductive.

Obviously, we must terraform the moon. Here come the Ewoks.

"Dust is the No. 1 environmental problem on the moon," said Apollo 17 astronaut Harrison Schmitt, who reported having a severe allergic reaction to moon dust during his mission in 1972.

How cool is it to know you're allergic to the frickin' MOON?

Some actual science about the dust...

m-242 The dyson spins the 'dirt out of the air at 100x the force of gravity.' So, at 1/6th of that, ~16x the force of gravity would it still work? That'd be 9.8 m/s2 x 16 = 163 m/s2. Good lord I'm a geek.

Under prolonged exposure, the explorers would be at risk for everything from mechanical failures in spacesuits and airlocks to lung disease,

Any moon base is obviously going to be airtight, and airlocks are going to be vented before exposure to the station's atmosphere. I really don't think we have to worry much about our astronauts breathing the contents of the vacuum of space.

Mercutio879: The dyson spins the 'dirt out of the air at 100x the force of gravity.' So, at 1/6th of that, ~16x the force of gravity would it still work? That'd be 9.8 m/s2 x 16 = 163 m/s2. Good lord I'm a geek.

Of course, if the force of suction in a vaccuum is generated through the difference in air pressure, this won't do you any good on the moon anyhow...

Alexis: I really don't think we have to worry much about our astronauts breathing the contents of the vacuum of space.

Well, there is the concern of surface walks and the dust getting in through airlocks during transfers. Plus, if erosion is that significant of an issue... yeek.

One of the famous early science fiction stories by either Hal Clement or Arthur Clarke featured moon dust causing trouble by sticking to everything.

The dyson generates the "100X earth's gravity" force by making the air/dirt rotate. If there was air of an equal density on the moon, the dyson would work just as well. The 100X part is simply a reference. They could have just as easily said the dyson spins dirt out of the air at 600x the force of the moon's gravity...

I thought Buffy destroyed it when she unleashed all those Slayers... and now they're threatning to destroy our moon bases?

"Dust is the No. 1 environmental problem on the moon,"

Um, I beg to differ... It's not a problem since it's natural, it's only a problem when we implant unnatural things, like ourselves and our buildings from Planet Earth.

Dumbass scientist.
 
2005-04-04 08:33:46 PM  
didn't heilein address that in the moon is a harsh mistress. something about all moon bases having to be mostly underground or something? it's been a very long time...

alas no, the #1 environmental problem on the moon is that there IS NO AIR.

Exactly why do we need to go back to the Moon, why would we need to establish a base there? If we are going to have a jumping off point into outer space, it'd be from orbit. Not that we can afford to do any of this anymore, we are flat broke as a nation.

A Lunar base would have access to the polar ice, which can be used for fuel, oxygen, etc. No orbiting station can provide that.

A little gravity is good for the body, too, on long-term missions.

Simple solution...just spray down the moon with a water hose.

Well, do you expect a space station to grow to become a rebel colony, then a nation, then a rival superpower? Hello? Try to think these things through, please.

Unless you were going for Mars, of course.

I lose all excitement over this stuff when I remember we have no money. Bush managed to fark EVERYTHING up.
 
2005-04-04 08:53:05 PM  
This is either poorly written, wrong, or I'm just tired.
Here goes...

If you aren't physically rubbing the damn dust against something, contact shouldn't do much? It isn't chemically coroding stuff, right?
It's not like the moon has strong winds to smash this against a base???
 
2005-04-04 08:53:10 PM  
In Bush Jr's America we don't need science anyway. We just need faith that the moon will be fine.

Does this mean that all the human artifacts left on the moon years ago might have eroded away by now?
If so, wouldn't that be a likely cover-up excuse for a landing that never happened?

/my tinfoil hat is also impervious to moon dust.
 
2005-04-04 08:54:55 PM  
Just do what Ben Bova wrote in Moonrise and Moonwar, build the station and pile 5-10 feet of regolith over it. You'll protect the station from small debris pounding it and keeping loose dust away from most of the station.

you mean absolute savlation right?
microgravity screws up your bodily functions Major.

building a station with artificial rotational gravity might be easier than dealing with the dust though...

Can i nominate Shnarpy for Bannination? or is this a threadjack and i would also be nominating myself for bannination?

Hello misleading topic ... erode away in a matter of weeks? but didnt they just say that theres no wind to blow the stuff around?

>>Moon dust is much more jagged than dust on Earth because there's no water or wind on the moon to toss it around and grind down its edges.

So no wind, no water ... no erosion? The biological effects are much more worrying than erosion anyway.

Chong: No, man. No, man, how'd he do all that other stuff, man? Like, how'd he make himself small, man. And, how'd he, like, how'd he get the reindeer off the ground, man?

Cheech: Oh, well, man, he had some magic dust, man.

Chong: Some magic dust?

Cheech: Yeah, magic dust, y'know? He used ta give a little bit to da reindeer, a little bit to Santa Claus, a little bit more for Santa Claus, a little bit more...

Chong: And this would get the reindeer off, man?

Cheech: Aw, got 'em off, man?!? Are you kidding, man? They flew all da way around da world, man!
