This week the results of three separate studies were published in the journal Science that discovered evidence of the existence of hydroxide (OH) or water or both on the surface of the moon. These findings require a re-examination of our assumption that the moon is dry.
This week the results of three separate studies were published in the journal Science that discovered evidence of the existence of hydroxide (OH) or water or both on the surface of the moon. These findings require a re-examination of our assumption that the moon is dry.
Carle Pieters of Brown University and her colleagues examined data transmitted by the Indian Chandrayaan-1 spacecraft and found that red ipanera light is absorbed near the lunar poles at wavelengths associated with hydroxide and water-containing materials. This report together with the other two indicate that the distribution of hydroxide on the lunar soil appears to be greater as you approach the lunar poles.
Another group, led by Roger Clark from the US Geological Survey, used data taken by the Cassini spacecraft when it passed by the Moon and discovered hydroxide at lower latitudes as well. A third group, by Jessica Sunshine, examined the infrared data taken by the Deep Impact spacecraft and also found traces of water and hydroxide and the retention of these particles in a continuous process on the surface of the moon - and that the solar wind could be responsible for their production. Taken together, these studies suggest that water or hydroxide in the polar regions on the Moon must have migrated there over time, being drawn to colder regions.
The results are published in the September 25 issue of the journal Science against the background of findings from about a week ago about the discovery of water ice near the south pole of the Moon by the LRO spacecraft, and a few weeks before NASA is going to cause for the intentional collision of the Centaur missile spacecraft into the Kabaus A crater near the south pole of the moon in the hope that the cloud of dust that will fly into space will also find water vapor, which NASA will sense by examining the spectrum of the cloud as well as in a sample taken by the LCROSS spacecraft that will pass through the cloud, a few minutes before it crashes on its own.
Still the moon remains drier than any desert on Earth. One ton of lunar soil would contain about one kilogram of water, the researchers say.
According to Peters, if the water droplets are as mobile as we believe they are - even a tiny fraction of them - this provides a mechanism for transporting the water to the shaded craters."
Traces of water were found in the moon rocks that arrived during the Apollo missions, but since their isotopes resembled those of water on Earth, the scientists treated this as earthly pollution and not as water from the moon. Even today, until these studies, the scientists believed that the presence of ice deposits in shaded craters was the exception and that on the rest of the moon water should not have been found at all, which contradicts the findings of the three studies.
Among the three missions - the first Indian mission to the moon - Chandrayaan 1 who recently lost contact with her, was designed to map the surface of the moon and determine its mineral composition. While the spacecraft was still operating, one of its Moon Mineralogy Mapper (M3) devices, built by NASA, discovered wavelengths from the surface indicating a connection between oxygen and hydrogen - evidence of the existence of water or hydroxide near the surface.
Cassini passed by the Moon in 1999 on its way to Saturn and also provided similar evidence, which has only now been examined in light of the Chandraian-1 findings, and the Deep Impact spacecraft, which is currently in the extension of its mission, recently performed a pass by the Earth and the Moon, and at the request of the M3 team of Chandrian-1 a similar measurement in which evidence of the existence of water or hydroxide was also discovered.

The water is not for settlement, the amount of water is too small
What is important in them is the continuation of the study of the solar system
.........
Water was found on the moon
To send all the ultra-Orthodox there because a) there is water there b) it is also closer to God according to their perception.
Um... it's clear to you that they didn't find waterfalls on the moon..
They must have found some water molecules on the moon...
And besides... yes, yes, this will be a "historical event"
I think it should be done. A glass dome is plastic around the moon is Venus start building it. Let's say that in 10 seconds we will finish it 🙂 and then we can live there .. we will start bringing water. We will grow trees there and more.
Maybe from there it would be easier to know why we are alone in the universe...
The fact that there is some kind of water is gratifying, but even if there wasn't, I think it's time to take some water from the earth (which doesn't lack water) and some people, and start the first colony on the moon "soon in our day" and we'll say Amen!
Asimov is the Messiah!
Hydroxide = OH
Hydroxyl = the hydroxide ion, OH-.
By the way, there is an error in the article. Should be OH and not 0H.
It was me 🙂

Michael,
When a compliment is received from you, you must treat it with the same degree of seriousness,
Just as he will admit to the question of whether he fasts on Yom Kippur...
Chen T:
All in all I wanted to compliment you in honor of the new year 🙂
The idea also appears in various speculations regarding the suitability of different planets for human habitation.
See, for example, here:
http://en.wikipedia.org/wiki/Terraforming_of_Mars#Sources_of_water
Hi Michael 🙂
First the idea is not mine. I read about it in some Medved book where a spaceship captain drives icebergs to the stars required for the asteroid content.
What I thought was that an unmanned spacecraft could be created that could remotely detect the elements present in one or another asteroid (or locate them using telescopes and then guide it from space), attach to the asteroid and propel it to the moon, Mars or wherever it is directed.
The wiki article speculates that water is below the surface when it comes to comets, but there is little information on the amounts of water found in asteroids. It is assumed that the comet was formed from gases, dust and ice, but it is not known whether it is water ice or another gas.
Chen T:
Happy New Year to you, too.
It is likely that there are some water-rich asteroids.
According to the popular opinion - comets contain a lot of water, but there is still much to explore in this matter. See, for example, here:
http://en.wikipedia.org/wiki/Comet#Debate_over_comet_composition
The idea you come up with seems nice.
Usually one thinks of ways to prevent an asteroid impact and you suggest to also think of ways to cause such an impact.
It's not easy because beyond the fact that the composition of a specific asteroid must be ascertained in advance, we want the asteroid not only to hit the moon but to hit it in a place where water can survive - that is - in a valley in the polar region.
This requires a great ability to control the movement of the asteroid - an ability that is not yet in our hands.
In light of the above, it seems to me that we are not there yet.
Happy New Year and a good autograph finale to Avi Blizovsky, Michael Rothschild and Yael Petar!
Dear scientists,
Are there asteroids that are actually giant glaciers moving around in space and could be the source of water or other gases on this or that planet? Could such a space source be a solution to the lack of water on the moon?
If there is water on the moon, then there is no need to send such a cargo there, nor is it necessary to send oxygen and hydrogen.
34 kg of fuel for every XNUMX kg of cargo including the weight of the spacecraft...
If it is possible to establish a colony that will need minimal maintenance in flight, then there is something to talk about and plan.
That's logical .
Opens a gate to the unknown.
Only this alone creates enough motivation to continue research/dreams.
Happy holiday

Strengthens the hands of all commenters here.
It sounds as if it strengthens the theory of the formation of the moon in a collision with Kadua, or beyond that - strengthens the theory according to which the water reached Kadua through external celestial bodies and comets (if it is proven that this is how they also reached the moon).
Yehuda Sabdarmish
It will probably cost a lot to transport the water to Earth, and if too much water is taken out in the form of wheat and food for the starving Earth, then the inhabitants of the penal colony on the moon will rebel. (Source: Robert Heinlein - A tyrant is white)

The reaction chain looks like Had Gadiya in its knowledgeable version.
You have to admit that strengthening is better than slaughtering.
Keep your hands strong, heroes of the army!
And you drew water in Shashon from the springs of salvation and the moon.
a question:
How much will it cost to bring water from the moon to our empty Sea of Galilee?
Other than that, happy new year

Thanks Ami.
Thanks to my father for the article. It's great that you can keep up to date with the newest things in science today on an Israeli website and in simple Hebrew with a successful explanation. A great and blessed website with a content editor and reporter from the best that the Israeli internet has known
People, you don't have to explain to the text writers that humans can't live on the moon with only this water.
Did you hear anywhere in the text the reference at all mentioning human life on the moon?
This article talks about the discovery, not about whether or not humans will be able to live there.
From what it seems you just want to show your wisdom, to show that you don't just believe one to another everything you hear/read, it's psychological.
Besides, instead of showing that you understand, you showed that your reading comprehension is not something.
It may also be that somewhere in your subconscious you felt left out, precisely because of the reason that people were not treated at all, humanity, and you wanted in some way to insert yourselves (humans) into this story.
Or I'm just wasting my time writing this comment and I'm the one who missed a paragraph.
Hydroxide or hydroxyl?
Someone who understands:
Please don't comment here anymore
The last thing a scientist needs is ynet type reactions
But to the best of my knowledge, in addition to water, the human body needs the minerals that are in the water, so the water that may be on the moon will not be enough to exist there.
No bears and no water
I think that after the joy and the rigorous tests to prove this claim, those involved in the field will have to ask themselves "how did we not come across this earlier" and draw the conclusions
post Scriptum
Indeed, this is wonderful, but the early joy means that in order for humans to live on another planet, a few more conditions need to be met: for example, gravity that is close to the Earth, oxygen, an atmosphere, and it would be better if it were a planet
