out-gassing of garment soils in deep space?

No, afaik the fumes evolve at higher temp (400?, 600?).


Sorry, wrong. The Teflon starts to break down at temps as low as 500
degrees *F* The previous poster was talking about temps in C.

The Teflon puts out tiny fibrous like stuff that floats through the air, and
while it kills Poly, it is none too good on humans, too. Since I have
birds, I have very little Teflon, and when it is used, I watch it like a
hawk. 500F is possible at the heat that barely burns bacon.

How about paper suites like clean room techs wear. Use them a few days
and then shoot them out to burn up in the trail of the engines. A large
supply won't take much space or weigh a lot.

` ` ` There is a problem: it gets cold in space. :-) Will a heater

` `
` ` Make all the clothes out of teflon, then roast 'em at 300C to clean
` 'em.
`
` ` Oops! Problem with that. The fumes will kill your parrot, then where

` No, 500? F (260? C). see http://tinyurl.com/cndss

Ah, OK, sorry, must be another example of people talking to me in
archaic units without specifying. ...I wonder how clean you could
get teflon by roasting at 200 (C of course)... On further reflection,
I bet the problem would be with fastener mechanisms - thread,
elastics, zippers. Might be hard to get teflon versions.

You can do your own vacuum test out in the garage (though radiation is
a bit harder to simulate) by putting some really nasty underwear in a
can, heating it to 250F, and pulling a hard vacuum on it for a day or
two, then remove the shorts and smear the crotch all over your
tongue... Taste anything?

It tasted like dirty underwear.
The smell however was different. It smelled like some pilots I met at a
fly-in in Indiana.

Meanwhile, over in a Mars discussion board, the question has been
raised about whether one can clean garments during an inter-panetary
mission, just by exposing them to the vacuum of deep space.
Let us presume that the major soils are body oils of the groin and
axillary areas.

They could make clothes edible. Then you could eat them after you are done
wearing them. Save all that water with washing clothes.
They make paper clothes. I'm sure they can make clothes out of grain or soy
that you can eat.
On the other hand I don't see why they just can't work naked and take a
sponge bath daily. You don't need clothes in a controled environment. All it
needs is a change in attitude. Clothes are a learned thing. Not a natural or
necessary thing. Modesty is learned and unnecessary.

Now, stop and think about what you're saying...do you really want to
*ingest* material that's too dirty to wear? Think about the basis of the
insult; "Eat my shorts."

Remember this, next time someone brings up sex in space (and I mean
crews, not tourists) again.

And...what becomes of the sponges?

astronaut parts drifting by me all day is enough to keep me bound to
Earth's gravity.

I'd be more concerned that they just kept drifting by!

ooooooo! yikes!

I'd be more worried about the bits that sluff off getting
into circuits and stuff. Take a look inside a PC that has
been setting around in a large, airy space in a home.

very interesting hypothesis.

can you support it with any experimental evidence?

Or is it an axiom.... in YOUR mind?

And the crew, for the near future at least, will be
taking the peeping toms along via downlink!

I think the people who decide whether a Mars flight gets funded, will
tell you that the downlink of the show, is 99% of what made it
sell-able.....

Is there any real reason why the Mars flight couldn't be funded by TV
networks and product endorsements? These two forces do a rather good
job of carrying on the charade that Professional and College Sports,
and the Olympics, are about athletics....

Apart from wanting some protection for delicate body parts, *pockets* are
immensely useful even in a controlled environment. If anything, they're
more useful in free fall than on Earth: small objects don't just stay
where you put them unless restrained somehow, and it's less convenient to
just carry things because moving around requires using your hands as well
as your feet.

All it needs is a change in attitude... Modesty is learned and unnecessary.

In principle, yes. In practice, unlearning such attitudes is not easy;
people are not happy about it and won't do it without urgent need. And
given that you need pockets anyway...
