Mini-SAR map of the Circular Polarization Ratio (CPR) of the north pole of the Moon. Fresh, “normal” craters (red circles) show high values of CPR inside and outside their rims. This is consistent with the distribution of rocks and ejected blocks around fresh impact features, indicating that the high CPR here is surface scattering. The “anomalous” craters (green circles) have high CPR within, but not outside their rims. Their interiors are also in permanent sun shadow. These relations are consistent with the high CPR in this case being caused by water ice, which is only stable in the polar dark cold traps. We estimate over 600 million cubic meters (1 cubic meter = 1 metric ton) of water in these features. Using data from a NASA radar that flew aboard India's Chandrayaan-1 spacecraft, scientists have detected ice deposits near the moon's north pole. NASA's Mini-SAR instrument, a lightweight, synthetic aperture radar, found more than 40 small craters with water ice. The craters range in size from 1 to 9 miles (2 to15 km) in diameter. Although the total amount of ice depends on its thickness in each crater, it's estimated there could be at least 1.3 trillion pounds (600 million metric tons) of water ice. The Mini-SAR has imaged many of the permanently shadowed regions that exist at both poles of the Moons. These dark areas are extremely cold and it has been hypothesized that volatile material, including water ice, could be present in quantity here. The main science object of the Mini-SAR experiment is to map and characterize any deposits that exist. continued.[/quote] ...the faster we get to Charon, the better.
Moon water. Bottle it and sell it on Earth. [img]http://filesmelt.com/dl/moon_water_the_low_gravity_water.jpg[/img]
I hope its fresh.
[QUOTE=starpluck;20513051]I hope its fresh.[/QUOTE] No it's like 5 billions years old.
I hope its not like Mars water from Dr.Who.
[QUOTE=Dr.Strangelove;20513065]No it's like 5 billions years old.[/QUOTE] so is the water on earth. [editline]03:45PM[/editline] so is everything on earth for that matter
[QUOTE=Sparkwire;20513088]so is the water on earth. [editline]03:45PM[/editline] so is everything on earth for that matter[/QUOTE] I know.. your point?
i was trying to be witty
That there is nothing wrong with the water.
[QUOTE=Sparkwire;20513103]i was trying to be witty[/QUOTE] Why would you do that? This is a serious moon-water discussion thread!
Awesome, next up, Moon Dolphins!
So the slammed a satellites in mister Moon's face for no reason at all....
[QUOTE=Dr.Strangelove;20513092]I know.. your point?[/QUOTE] Any water can be drinkable no matter the age.
[QUOTE=Baldr;20513129]So the slammed a satellites in mister Moon's face for no reason at all....[/QUOTE] We found water; entire thing justified.
I highly doubt that it is consumable
[QUOTE=CPShArp;20513136]Any water can be drinkable no matter the age.[/QUOTE] He asked whether it was fresh, not whether is drinkable. Let's say you have a chicken breast in your freezer for a few mothers. It's not fresh, it's a few months old. you can still cook it and eat it fine. Much like the forzen water on the moon.

Now, the next person who says there's nothing of value on the Moon can bring a gun to his head.

It doesn't have to be $8 Fiji water in order to be fresh.
Bet it tasts so much nicer than earth water.

[QUOTE=Dr.Strangelove;20513065]No it's like 5 billions years old.[/QUOTE] yeah we'll get there and the water is spoiled oh wait
[QUOTE=Eudoxia;20513218]Now, the next person who says there's nothing of value on the Moon can bring a gun to his head.[/QUOTE] The fact that it's not the Earth but still remains accessible is value enough, IMO.

Stuff that isn't "fresh" has decomposed. No air, or life on the moon, therefore it can't decompose.
[QUOTE=gmaster;20513325]Stuff that isn't "fresh" has decomposed. No air, or life on the moon, therefore it can't decompose.[/QUOTE] Water can't decompose, period. I thought we made that clear? Water is water.
Moon civilization here I come!
Oh god I'm writing a homeworkpaper about "Search for water" for my astronomy class. This article is heaven-sent.
[QUOTE=Dr.Strangelove;20513165] It's [I]ICE[/I][/QUOTE] Yeah and?
[QUOTE=gmaster;20513325] No air, or life on the moon[/QUOTE] :ssh:
Uh, question. How concentrated are we talking, here? They claim "a couple meters thick", but does that necessarily mean solid ice? Or do we have to process a hundred tons of regolith for every few pounds of ice? Either way, considering the tiny amounts of water the ISS runs on with it's recycling systems at full capacity, that could be enough water to support whole cities.
