Water on the Moon

Posted November 23, 2009 8:21 AM by tinypilot18

Recently, NASA's LCROSS probe discovered beds of water - ice on the Moon - and in mass quantities. This finding occurred on the lunar South Pole in a crater called Cabeus. When the debris from the impact of the LCROSS probe was analyzed, the signature of water was seen in both infrared and ultraviolet spectroscopic measurements. Based on these measurements, it is estimated that there was approximately 100-kg of water in the immediate view of NASA's instruments.

The LCROSS discovery has led most scientists to believe that there must be more water nearby. It is hypothesized that this water is probably left over from ancient comets that hit the Moon billions of years ago. When melted, it could be used to create rocket fuel - or for astronauts to drink. The discovery of lunar water could save millions for NASA, considering that putting a pound of payload on the Moon costs between $50,000 and $100,000.

Confirming Suspicions

Based on detections from previous lunar missions, scientists have long suspected that permanently-shadowed craters at the South Pole of the Moon could contain frozen water. Water was detected on the Moon by a previous probe, but it was in very small amounts and bound to the dirt and dust on the lunar surface. During the investigation, water wasn't the only compound found in the debris, but the identity of the other compounds has yet to be determined.

These findings indicate that the Moon's poles may contain more data on both lunar history and solar system history, because these permanently-shadowed areas are extremely cold and trap things that encounter them. The recent LCROSS finding could be ice that has been on the Moon for billions of years.

The Augustine Report and Beyond

Last month's Augustine Report on the future of space travel, commissioned by NASA, states that unless there is outside funding, President George W. Bush's plan of sending astronauts to the Moon by 2020 and creating a Moon base, and then onto Mars, will not happen. Very soon, President Barack Obama is expected to make a historic decision that will affect the space program for decades to come. The LCROSS finding will certainly put pressure on him when it comes to that decision. If continuing to explore space is worth the expense, there may be more out there than we expect.

From what I know it has been long known that there was ice, water, on the Moon.

Maintaining the information as a secret of the US simply lost value over time.

I myself am of the opinion that at this point practical uses of our space prowess for planet protection and species survival creating a robust infrastructure, trump exploration for the sake of exploration.

I am particular wanting that at least 200 people be permanently living in near Earth orbit, comfortably doing planet defense work appropriate to known threats that call for looking down and looking out.

They talk about having water on the moon is the first step to colonization.

For a number of reasons, one being it is an energy source. Which you touch off of.

The LCROSS discovery has led most scientists to believe that there must be more water nearby. It is hypothesized that this water is probably left over from ancient comets that hit the Moon billions of years ago. When melted, it could be used to create rocket fuel - or for astronauts to drink. The discovery of lunar water could save millions for NASA, considering that putting a pound of payload on the Moon costs between $50,000 and $100,000

Which brings us to another question.

If we have issues extracting energy from the water supply on earth, Why would it be easier to do it on the moon?

"If we have issues extracting energy from the water supply on earth, Why would it be easier to do it on the moon?"

Not easier less costly then shipping fuel to them.

Just because it would be cheaper, does not mean it is worth doing.

Point I was going to add is technology has to improve.

It would be if your living on the moon. If that was case I would also think that there would be more effort spent to improve it.

Necessity is the mother of invention.

This is where things need to be developed concurrently.

During which time you hear from the nay sayers, why do we need to go to the moon. Thinking its absurd to that the world's tech advances are making the world a better place because they would have been developed anyways. Closed mindedness from them. Going back to my first sentence.

With them not realizing even the first effort to the moon yielded technology and development that helped right on earth.

Presumably the solar radiation is stronger up there as there is little atmosphere to attenuate it?

Had a hard time with that, sounded like a statement but had a question mark.

Had to look up to verify attenuate.

ah yes, it would be easier without a atmosphere.... said in a unsure voice.

Yeah, maybe that's why I put the question mark? Or was it?

Everybody knew that there was water on the Moon. Also, it is a known fact that there was on Earth, another very advanced civilisation some 40,000 years ago. The arts, the science, and engineering have reached pinnacles unknown in our days....

And, of coarse, colonising the Moon was done. All industries have been moved over there, until they discovered that certain industrial gases destroy the ozone layer. Then it was the great global warming scare.

A great scientist, Fase Orp, decided that reducing the emanations will preserve the ozone layer, the atmosphere and life on the Moon. How was it implemented? Shutting down industries. In one thousand years there was no more global warming. In fact the Moon started to get cooler, and cooler, until water was completely frozen. All lunar inhabitants moved back on Earth (or died). Helas, with no industry, the Earth civilisation decayed. Life expectancy dropped abruptly, remaining people started to live in caves, to hunt for food. From the debordant art, only some rudiments of painting have been noticed in archaeological finds in the caves.

And all started with Fase Orp.

We don't learn anything from the history.

By the way, they will discover ice on Mars, too!
