Boerseun Posted January 25, 2011 Report Posted January 25, 2011 You would need a sealed crust. 20 meters below the surface will still not apply any pressure on water to the point of making it liquid, because the surface matter has cracks and any liquid water will boil away in the vacuum through the cracks, out the surface. It's like it was said before in this thread - if you have two stones in your hand with water in between, you will not apply any pressure on the water. Quote

modest Posted January 26, 2011 Report Posted January 26, 2011 Also, what if there is a greenhouse made of volcanic glass with a pressurized and heated interior? ~modest Moontanman 1 Quote

Moontanman Posted January 26, 2011 Report Posted January 26, 2011 Correct. What if? Yeah, and what if these volcanic glass greenhouses could reproduce and spread across the surface of the Moon?! modest 1 Quote
modest Posted January 26, 2011 Report Posted January 26, 2011 I don't think we can rule out volcanic glass greenhouse asexual reproduction on the moon Here is a scientific article supporting it: http://www.his.com/~pshapiro/acorn.on.moon.html ~modest Boerseun 1 Quote

Without a doubt. Since ice has been found it is about certain that a liquid aquifer exists underneath the regolith just South of those regions towards the equator. All we need to do now is drill.

All we need to do now is drill. I see no reason what so ever to assume there is an aquifer on the moon because of ice deposits in craters at the moons pole. How do you make the connection? What evidence do you have of this aquifer? Quote

How do you make the connection? What evidence do you have of this aquifer? There are many spots on Earth where an artesian well connected to an underground aquafer will come bubbling up out of the ground. Why would it be any different on the moon except for if it happened in those craters near the poles on the moon it would immediately freeze? I bet there are examples here on Earth near our poles.

Moontanman Posted January 28, 2011 Report Posted January 28, 2011 There are many spots on Earth where an artesian well connected to an underground aquafer will come bubbling up out of the ground. Yes this is true, the Earth does have aquifers, the Earth is completely different than the moon. There are plenty of reasons why the Earth has aquifers, An atmosphere that allows rain, rivers, lakes and oceans would be at the top of the list of reasons why the Earth has aquifers, the Earth is awash in water, water is a significant and important part of the Earth. Why would it be any different on the moon The Moon has no atmosphere, it's volatile elements were driven off during the moons formation, the Moon has no evidence of underground water, the small amount of ice in those isolated craters almost certainly comes from comet impacts. except for if it happened in those craters near the poles on the moon it would immediately freeze? If it happened on the moon we would see evidence of it, we would see plumes of steam as the water is driven to the surface, there is no evidence of out gassing of water on the moon. I bet there are examples here on Earth near our poles. Water bubbles out of the ground in many places on the earth, the poles are covered in perma-frost and this would inhibit water bubbling up at the poles but I am sure it happens on the Earth's poles as it does elsewhere but again i see no evidence the moon has aquifers.

Moontanman Posted January 28, 2011 Report Posted January 28, 2011 The very fact that ice exists could mean there could be aquafers and or springs. No, the ice suggests water from cometary impacts has condensed in craters that are in permanent shadow at the Moons poles. Aquifers or springs on the Moon would result in out gassing of water at random points all over the Moon, no such out gassing has been seen. Ice at the Moons poles is not compelling evidence of the Moon having an aquifer, there is how ever considerable evidence the Moon has almost no water and almost no carbon, this does little to support the idea of life on the Moon.

Incorrect, how can it all out gas if the water is frozen near the surface such as in the craters and below the regoltih where surface tension holds it there like in a sponge? If what you are saying is true then no ice could be found either.Ice evaporates away just as water does? I would think comet impacts bring water to the moon and surface tension holds some of it there like a sponge and some of it (not all of it) soaks down into the regolith while most of it does evaporate into space.

Water has to be liquid to soak into the regolith, for water to be a liquid requires atmospheric pressure, the moon has no atmosphere and so has no liquid water. if it's cold enough, like a permanently shadowed crater, ice will condense from gaseous water. No need for or evidence of an aquifer on the moon. If it's cold enough water ice will not evaporate away in a vacuum. Quote

RE: # 32 Looks as if you forget pressure also increases the deeper you go below the regolith. Water doesn't have to be in the atmosphere quit assuming so. "You can get the pressure at that depth by multiplying the depth in meters by 3,000 then by 1.6. It is 96000 Newtons per meter squared or 0.95 standard atmospheres at 20 meters. In other words, pressure and temp needed to keep water liquid should be found about 20 meters below the surface of the moon. ~modest " Digging 20 meters down should be easy on the moon even with a solar powered drill rig!

The weight of 66 feet of over burden is not the same as gas pressure, the gas pressure between particles at 20 meters is still zero, water would still sublime into a gas at 20 meters. Even though you are the one making wild claims here i have offered evidence at every turn you are mistaken but you have supported your ideas with nothing but more claims. There is no evidence of water out gassing on the moon, comet impact water would have to be liquid to "soak" into the regolith, if there was a aquifer on the moon you would expect to see out gassing of water at random points all over the moon, not just at the poles in certain craters. Show some evidence to back up your idea of an aquifer on the Moon, ice in shadowed craters at the pole is not evidence of an aquifer on the moon.... Quote
