On the moon, discovered large reserves of water


Supplies of water on the moon is much larger than previously thought. According to the analysis of NASA data, which was published on Friday, this discovery could be a decisive argument in favor of a manned base on the lunar surface.

This discovery was made in the course of a bold experiment by NASA. Last year, they sent a rocket that has run out of fuel, right in the lunar crater at the speed of 9,000 kilometers per second. Then, fragments of which were formed as a result of the collision, were analyzed using two satellites. They found that crater contained water as ice, and a set of other resources, including hydrogen, ammonia, methane, mercury, sodium, and silver.

NASA announced its revolutionary discovery in November of last year. Today, became available a more detailed analysis. According to an article in the journal Science, is based on six research papers, the content of water on the moon is much larger than previously thought, and about twice the water content in the Sahara desert.

"The soil is very wet," - said Anthony Colaprete, co-author of an article in the journal Science and cosmologist from NASA research center in California. He and his colleagues estimated that 5.6 percent of the weight of the aforementioned lunar crater, are in the form of water ice. In other words, one ton of lunar rock can be 45 liters of water.

Water on the Moon, has long remained a mere dream, as in the case of finding this valuable resource, you can save a lot of money to bring water from the ground. Researchers from NASA calculated that half-liter bottle of water on the moon would cost 50,000 dollars, due to the costs associated with the delivery of water to Earth’s closest neighbor in the solar system.

The chances of the U.S. involvement in setting up a lunar base is small. Barack Obama recently canceled NASA program to return astronauts to the lunar surface, to be held in 10 years. But the agency is working on an even more ambitious program for the delivery man to Mars.

NASA to carefully select the clashes. Because of the slope of the lunar axis, the bottom of large craters at both poles are not exposed to direct sunlight for billions of years. NASA selected the crater, called Cabeus, was near the south pole.

Cabeus - a cosmic trap. Any material got there, stays there forever. "There’s almost no energy to heat the molecules, so they can not fly away from there," - said Randall Gleydstoun, co-author of an article and a planetary-profit research institute in San Antonio.

Dr. Gleydstoun and other researchers believe that Cabeus contains material arrived from outer space that was going there for over a billion years old.

The number of detected water, 50 per cent higher than the initial estimate of NASA. Some measurements suggest a "lunar permafrost" covering about 30% of the lunar south pole, where ice lies just beneath the surface. Only our informers tell the news on the latest news.
