Sunlight on the underground lake evaporating the ice to form clouds
and fall as snow, all underground? The nuclear furnace at the centre
of the Moon? It might work if your brain ever did.
Tell us about the canals on Mars instead, Lowell believed in 'em.


Well, you don't need underground nuclear furnaces when any given point on
your surface faces the Sun for about half a month, and doesn't face the
Sun at all for the rest of the month. That's bound to create a small
temperature differential that may result in melting and refreezing.


On an underwater river... Ever been in a cave or in a mine?
No, of course you haven't.
Do you know how to snip and ignore any obvious point made
that you disagree with?
Yes, of course you do. Any ****wit can do that.

Now its my turn to snip.
snip idiotic crap from the cretin Kahn

See, I can do that too. Ain't I ****ing clever?

Yes Androcles, you're one clever monkey.

Surely the amount of **** you throw around is the ultimate sign of
your intelligence. Don't forget to collect some more **** from behind
your ass, you'll need to spread your intelligence around after all.

The Moon water was discovered by three separate spacecraft. The Indian
Chandrayaan-1 was the one given the credit for the discovery, while the
Deep Impact and Cassini probes were given the credit for the
confirmation. Chandrayaan-1 was specifically looking for this signature,
before it stopped working, so it looks like it completed this work. The
Deep Impact comet impactor probe swung by the Moon on its way to comet
Tempel 1, and detected the signature back then too. And prior to that
the Cassini Saturn probe passed by the Moon too and detected it. It's
kind of backwards, as the verifications came from probes that went
beforehand, whereas the discovery came afterwards.


CBC News - Technology & Science - Water traces found in moon's dirt
"The water was spotted by spacecraft that either circled the moon or flew by. All three ships used the same type of instrument, which looked at the absorption of a specific wavelength of light that is the chemical signature of only two molecules: water and hydroxyl. Hydroxyl is one atom of hydrogen with one atom of oxygen, instead of the two hydrogen atoms in water."

The water seems to be widespread throughout the Moon, it's not just in
shadowed Moon craters. The original Apollo astronauts brought back Moon
rock, but they couldn't find significant amounts of water. Or at least
they couldn't tell whether the water was from the Moon or Earth. This
resulted in the current favoured theory of Moon formation: The Giant
Impactor, which states an Mars-sized rock hit the Earth early on, and
created the Moon.


SPACE.com -- It's Official: Water Found on the Moon
"Apollo turns up dry


When Apollo astronauts returned from the moon 40 years ago, they brought back several samples of lunar rocks.


The moon rocks were analyzed for signs of water bound to minerals present in the rocks; while trace amounts of water were detected, these were assumed to be contamination from Earth, because the containers the rocks came back in had leaked.


"The isotopes of oxygen that exist on the moon are the same as those that exist on Earth, so it was difficult if not impossible to tell the difference between water from the moon and water from Earth," said Larry Taylor of the University of Tennessee, Knoxville, who is a member of one of the NASA-built instrument teams for India's Chandrayaan-1 satellite and has studied the moon since the Apollo missions."

The widespread distribution of the water might be the start of a new
theory of Moon formation, though no one is really saying this directly yet.


Water Present Across The Moon's Surface, New Research Shows
"Isaacson said the M3 results were a huge surprise. “There was no evidence that this was possible on such a broad scale,” he said. “This discovery turns a lot of the conventional thinking about the lunar surface on its head.”"

http://www.sciencedaily.com/releases...0924093559.htm


http://www.cnn.com/2009/TECH/space/09/24/moon.water/index.html

"One ton of the moon's surface -- in which the water's ingredients are
held -- could yield as much as 32 ounces, or one quart, of water,
according to three reports from research teams who studied data from
three spacecrafts."

That is 2 lbs of water/2000 pounds of dirt in theory - and if the
surface is like the volume. *Want to bet your life on it? 55 gallons
would require processing at 100% efficiency 110,000 lbs of regolith.
That's silly.

"Although that amount isn't large, said geological sciences professor
Jack Mustard, the findings show "there are ways you could convert
these amounts of water into higher amounts" that could support human
activity."

That's not even a lie. *That's flat out stupid.

Stupid is as stupid does, as par for most anything NASA or DARPA.

I've been informed that we can also get blood from a rock. At least
that's what most Republicans think of, as to where all the necessary
loot is going to come from in order to pay for their decades of
mistakes and playing war games for the sake of energy profits, as well
as their job and nifty benefit security.
