Default NASA's LCROSS Impacts Confirm Water in Lunar Crater



MOFFETT FIELD, Calif. -- Preliminary data from NASA's Lunar Crater
Observation and Sensing Satellite, or LCROSS, indicates the mission
successfully uncovered water in a permanently shadowed lunar crater.
The discovery opens a new chapter in our understanding of the moon.


The area of the moon this crater is located at, is said to be the coldest
place in the solar system.

That being the case how are humans supposed to survive there long enough to
make use of the water?

Our NASA LCROSS team is on serious drugs, as in cover thy butt or
else.

Guess what folks, there’s water to behold from creating any crater,
because basalt always has at least 50 ppm to begin with (750 ppm).
Secondly, keeping warm is not a problem, as is with keeping yourself
and whatever technology cool. Stirling energy conversions from
photons to electrons is really going to become nifty when there’s such
a terrific thermal differential to begin with.

At 3e-15 bar, any form of water becomes nearly explosive in how it
would unavoidably react to such extreme vacuum, and there’s all sorts
of secondary IR that even manages to get into the deepest of polar
craters from time to time, sufficient thermal energy to boil off most
any raw/naked volume of ice at that extensive of vacuum.

The 50750 some odd PPM of water that’s sealed in surface and crust
basalt is one thing that’s likely sure enough there to behold.
However, raw/naked ice under a crystal dry layer of physically dark
dust is not likely to exist/coexist unless that moon either isn’t very
old, and/or there’s water that’s still leaking out from a substantial
reservoir or aquifer inside the moon.

AP / “The lunar crash kicked up at least 25 gallons and that's only
what scientists could see from the plumes of the impact, Colaprete
said.”

And yet there’s still no UV florescence imaging or public view of
those original gamma spectrum readings. So, it’s still pretty much
insider and/or need-to-know business as per usual, whereas raw/naked
ice in the vacuum of space apparently doesn’t have to go by any pesky
laws of physics or need of independent peer review.

The LCROSS 20 meter crater is basically giving up 1e3 m3 worth of
displaced and/or partially vaporized basalt that’s mineral saturated
and supposedly containing 250 PPM water. That’s roughly 3.5e3 tonnes
worth of lunar basalt w/minerals to start off with, and by taking a
little over 11% of that as having been vaporized is perhaps what our
NASA has claimed as having given off measurable water that such frozen
basalt should have. I think it vaporized closer to 25% if not as
great as 33%, which means the h2o content of that basalt wasn’t as
great as 100 PPM.

I would favor that our moon is about as dry as things get, though I’ll
give a very remote possibility of there being an underground artisan
cache of water that has been gradually leaking out and into just that
continually frozen crater, is at least technically possible, although
it's extremely unlikely those unavoidable h2o vapors weren't easily
detected by astronomers and their various sensitive spectrometry as of
at least decades ago.

Here's yet another image of the sorts of crystal dry minerals that our
moon has to offer. These hue saturations are not bogus/false colors,
just the original colors as having been enhanced, similar to the nifty
eyecandy that Hubble gets published and accepted all the time.

In LRO UV fluorescence imaging, this amount of mineral hue secondary
reflectance should be at least ten fold better yet, and a good
thousand fold better resolution when obtained from just 50 km. Any
sign of water vapor as coming off such a naked surface of crater
shadowed ice would have been unavoidably unmistakable.

So, apparently our NASA gets to lie, and we don't, because at roughly
100250 ppm of what's supposedly h2o within moon basalt, as such it
would have only required vaporizing a few hundred tonnes of basalt in
order to provide 25 gallons (94+ kg) of water. In other words, at 250
ppm it would only require vaporizing 400 tonnes of basalt in order to
release 100 kg of its water, along with releasing at the very least
1000 kg of sodium (though many areas of the lunar surface are rich or
saturated in sodium to the tune of 50,000 ppm), plus there's many kg
worth of other minerals and of course there's 30,000100,000 ppm O2 =
1240t that shouldn't have been all that unexpected.

http://en.wikipedia.org/wiki/Basalt
Basalt generally has a composition of 45–55 wt% SiO2, 2–6 wt% total
alkalis, 0.5–2.0 wt% TiO2, 5–14 wt% FeO and 14 wt% or more Al2O3.
Contents of CaO are commonly near 10 wt%, those of MgO commonly
in the range 5 to 12 wt%.

High alumina basalts have aluminium contents of 17–19 wt% Al2O3;
boninites have magnesium contents of up to 15% MgO. Rare
feldspathoid-
rich mafic rocks, akin to alkali basalts, may have Na2O + K2O
contents
of 12% or more.

"Calculation of oxygen yield (as released by hydrogen gas reduction
of ilmenite) show that (1) beneficiated basalt will provide the most
oxygen (8–10%)"

Absolutely correct, and Yes, basalt rock has 50750 ppm of h2o. So
what?

Our NASA LCROSS team is on serious steroids and/or hard drugs, as in
cover thy butt with all the media hype, spin and eyecandy meds they
can muster, or else. It’s called job security, except theirs is with
nifty benefits and COL insurance.

They must think our president/BHO and his staff of well educated
advisers are easily snookered and dumbfounded past the point of no
return. Because guess what folks, there’s always water to behold from
creating any crater, mostly because basalt always has at least 50 ppm
to begin with (750 ppm). Secondly, keeping yourself warm is really
not a problem, as is with keeping yourself and whatever technology
cool. For those polar crater locations, Stirling energy conversions
from photons to electrons is really going to become nifty when there’s
such a terrific thermal (light to dark) differential to begin with.

Once any molecules of water/ice are freed at 3e-15 bar, it becomes
nearly explosive in how it would unavoidably react by expanding into
such an extreme vacuum, and there’s all sorts of secondary IR that
even manages to get into the deepest of those polar craters from time
to time, contributing sufficient thermal energy to boil off or rather
sublime most any raw/naked volume of ice at that extensive vacuum, not
to mention the moon itself is also radiating 22 mw/m2 of it’s
residual and/or thorium core heat (thicker polar crust has got to be
worth at least 10 mw/m2).

The 50750 some odd PPM of water that’s sealed in surface bedrock and
crust basalt is one thing that’s likely sure enough there to behold.
However, raw/naked ice under a crystal dry layer of physically dark
carbon dust is not as likely to exist/coexist unless that moon either
isn’t very old, and/or there’s water or mineral brine that’s still
leaking out from a substantial reservoir or aquifers inside the moon.

AP / “The lunar crash kicked up at least 25 gallons and that's only
what scientists could see from the plumes of the impact, Colaprete
said.”

And yet there’s still no UV florescence imaging or public view of

water, that such frozen basalt by eights should have. I think the
impact vaporized closer to 25% if not as great as 33%, which means the
h2o content of that basalt wasn’t as great as 100 PPM, but then who’s
really counting since ordinary physics and easily peered replicated
science does not matter.

I would tend to favor that our physically dark lunar surface is about
as crystal dry as things within such a terrific vacuum environment
could ever get, though I’ll give a very remote possibility of there
being an underground artisan cache of water or mineral brine that has
been gradually venting/leaking out and into just those continually
frozen craters is at least technically possible, although it's
extremely unlikely those unavoidable h2o vapors weren't easily
detected by astronomers and their various sensitive spectrometry
methods as of at least decades ago.

Here's yet another image of the sorts of crystal dry minerals that our
moon has to offer. These hue saturations are not bogus/false colors,
just the original colors as having been enhanced on behalf of
observationology, similar to the nifty eyecandy that Hubble gets
published and accepted all the time.

In LRO UV fluorescence imaging, this amount of mineral hue as
secondary reflectance should be at least ten fold better yet, and a
good thousand fold better resolution when obtained from just 50 km.
With their LRO extended dynamic range, any sign of water vapor (atoms
of h2o) as coming off such a naked surface of any crater shadowed ice
would have been unavoidably unmistakable. Of course this means there
really is not such raw/naked ice to behold.

So, apparently our NASA gets to lie their public funded butts off, and
the rest of us don't, because at roughly 100250 ppm of what's
supposedly accessible h2o within moon basalt, as such would have only
required vaporizing a few hundred tonnes of basalt in order to provide
those 25 gallons (94+ kg) of water. In other words, at 250 ppm it
would only require vaporizing 400 tonnes out of the 3.5e3 tonnes of
basalt in order to release 100 kg of its water, along with releasing
at the very least 1000 kg of sodium (though many areas of the lunar
surface are rich or saturated in sodium to the tune of 50,000 ppm),
plus there's many kg worth of other minerals and of course there's
30,000100,000 ppm O2 = 1240t that shouldn't have been all that
unexpected or hard to detect.

"Calculation of oxygen yield (as released by hydrogen gas reduction

oxygen (8–10%)"

Of course there’s lots of good old hydrogen and helium 3 (3He at 10
ppb) that need not be wasted.

“The energy content of 3He is: E(3He)= 2e8 kWh/kg-1 ... If Fusion is
the process of obtaining energy by adding things together” could be
interpreted as worth $2.5M/kg, especially as fossil duels are made
spendy or illegal to use unless their exhaust emissions are fully
certified as green, and average consumer cost of energy hits $0.25/
kwhr

A serious solar farm of mylar mirrors could vaporize lunar basalt
rather nicely, especially in that 3e-15 bar vacuum.

At perhaps as little as one kg per 100 m2 mirror shouldn't be so
unlikely. A full tonne of such deployed mirrors is thus offering 1e5
m2 of reflected and focused solar energy into a bedrock area of
perhaps 4 m2.

At only 90% efficiency is still offering 3.4e6 w/m2, which at 3e-15
bar should vaporize something. That collective 1e5 m2 of mylar mirror
efficiency as focused down to 4 m2 should actually become worth 3.6e6
w/m2.
