NASA finds [significant] water on the moon


news.yahoo.com
A "significant amount" of frozen water has been found on the moon, the US space agency said Friday heralding a giant leap forward in space exploration and boosting hopes of a permanent lunar base.

Preliminary data from a dramatic experiment on the moon "indicates the mission successfully uncovered water in a permanently shadowed lunar crater," NASA said in a statement.

"The discovery opens a new chapter in our understanding of the moon,"

I'm still wondering how this will help propell a moon base though...


i was thinking about that too...im not a genius what so ever, but here were a few conclusions i reached:

It costs a *Lot* of money for every pound of anything blasted into space. If there is already water on the moon, that eliminates an incredible amount of the long haul we'd have to take to the moon.

If water is already there, we can take some seeds, some dirt, some filters, maybe some metal and glass, and poof we'd have a settlement (i generalize...i know)

As opposed to lifting millions of gallons of water ourselves - continuously - to sustain any life we'd have on a lunar base.

Basically - finding water on the moon - makes a lunar colony possible - because without lunar water - the price tag of even beginning such a feat would be unachievable.

Also India discovered water first, then Nasa claims this

I bet it was Nasa that made India lose contact

Evidence of water on the Moon was first found in 1990 by the US Navy's Clementine mission.

The observations by Chandrayaan-1 were a joint effort between India and NASA. NASA provided the instrument, India provided the spacecraft. To say that India discovered water first is not accurate.



This selection is contingent upon NASA selecting, developing and delivering the M3 Instrument to ISRO for integration on their spacecraft. ISRO allocated spacecraft resources (power, mass, data bandwidth, mechanical envelope, and location) for the Instrument, and we are easily accommodated by those resource allocations. The participation by M3 on the Chandrayaan-1 Mission is on a "no-exchange-of-funds" basis.

The presence of liquid water requires a significant atmosphere. The presence of water ice does not. The Moon has no significant atmosphere.

Wrong. The presence of water AND ice require an atmosphere because ice can vaporize into space vacuum almost as easily as water because of Sublimation!

Have you forgotten your chemistry and physics my friend?

Where did the moon come from? Probably a chunk of the earth after a collision, right? ie. Part of the Earth. Does the Earth have water? Yes. Does the Earth have an atmosphere? Yes. Would the Moon that was formed from the Earth have water and an atmosphere? NASA says no!

The sublimation temperature of water ice in a vacuum is 152K. The temperature in the shadowed areas of Cabeus crater is well below that (45-50K), that is one reason it was chosen as the impact site. Water ice would not sublimate there.

The origin of the ice is unknown. It is highly unlikely that it is remnants of the formation of the Moon (but remotely possible I suppose). Cometary impacts are more likely.

Suppose you meant negative K. But tks for that!

"Would not sublimate"(in a billion or several) years is something I question!

There is no such thing as negative Kelvin. I meant what I said.

BTW, comets have no atmosphere, have water ice, and have been around for billions of years.
