Re: Ice in space (Was: Present life on Earth (Was: Life outside the Earth))

Martin 53N 1W,
Thanks for all the terrific feedback. However, your notion of what a m3
block or sphere of raw ice having "19043440 seconds is about 220 days,
or 7 months" as a purely math simulated and thus soft-science form of
conjecture having been somewhat corrected by lord/wizard Jonathan
Silverlight seems a little too good to be true. As why is it taking so
much effort and/or applied technology for keeping ISS cool, whereas our
ISS is only illuminated half of the time (thus surviving via 50% of the
time having it's circulated surround of water getting the life saving
opportunity of cooling off by the shade/nighttime of mother Earth) and
I believe it's nowhere as situated within nearly as much of a vacuum,
as well as for their being quite nicely shielded by the hot and nasty
Van Allen zone of death.

How hot and nasty would ISS get if it was having to survive as 100%
solar illumination?

Where within your formula was the near absolute vacuum of 1e9 atoms/m3
applied?

Wouldn't that sort of near absolute vacuum tend to just pull raw ice
apart?

Isn't there initially more than 1 m2 worth of surface area to work
with?

Shouldn't the transperancy of ice affect/modify the rate of
sublimation?

How about contributions of secondary IR as derived off the albedo of
Earth and that of our moon, as well as per secondary/recoil photons?

I can appreciate that at one bar that said ice should survive as you've
indicated if it had merely a singular illumination of 1.368 kw/m2.
However there's probably no such thing as clean ice in space, thus an
albedo of .9 might be a wee bit conservative, not to mention of what
happens at good vacuum and along with all sorts of other influx is
where the likes of dirty raw ice might not survive nearly as long
unless surrounded by dry-ice.

Anyway;
Where's the simple hard-science of ice in sapce from team ISS or via
any space based testing?

Isn't the hard-science and thus objective knowledge basis of raw ice
having to survive in space worth squat?
