Of course, the existence of at least some human lunar base almost everything is dependent on whether there is water on the Earth's satellite. All well remember the epic past 18 years, during which it was determined the presence of water on the moon. In reality, this is just one more beyond the "invention of the bicycle."
In 1994, the American automatic interplanetary station "Clementine" was held radar survey of the surface layers of the Earth's satellite, during which the results are encouraging, but not entirely clear results. AMC's Lunar Prospector was also involved in the search for water, producing a frozen neutron absorption surface layers of the moon. Finally, in 2009, the Indian "Chandrayaan-1", Galileo also used to search for water.
Why all this? After all, the world of lunar soil abound. So, for example, "Apollo" was brought about three hundred kilograms of soil per se, with a significant portion of the samples was lost. Arlene Krotts South American astrophysicist, a member of the Colombian Institute, tried to answer those questions.
Everything is pretty easy: the scientists who followed in the 60's and 70's the notion that the moon is anhydrous celestial body, made the assumption that the standards of the lunar soil, which brought the "Apollo", already have been contaminated after it returned to Earth. Only in this way could explain the existence of water, where, according to the views of the scientific community, it was not.
In addition, when the traffic was the lunar soil, NASA used is not perfectly sealed containers, resulting in loss occurred outside of the regolith particles, and it is made plausible version.
Whatever it was, the development of science going on at the time, not just in the West, Russian Alliance had other sights on this problem of.
AMC "Moon-24 ", which is produced in the 1976 final for today Myagenko landing on the satellite, produced ground, which was delivered soaring module back to Earth. The data relating to the weight of soil is different (from 160 to 170 g), but not in this case. This mission is unparalleled and distinguished from the technical side, was the most logical method which inspects the presence of water on the moon if traces are available, there is a strong possibility that they subsurface layers.
Of course, the Russian researchers, using the method of infrared spectroscopy, analyzed the material and found unambiguous traces of water (0.1% by weight of lunar soil), the water content increased to the extent that, as the depth increased. The scientists also reported that hardly could have happened earthly contamination of samples with water, as regolith has a tendency to absorb water from the air.
As a result, a conclusion was made that the moon is, very few millions of tons of water. Why "at the lower extent?" Since the place (Sea of Crises), was taken from the ground, is not on the pole, so that the water content is not very probable, but rather the contrary: after the loss of water at the poles of the lunar soil goes much weaker.
These research results in 1978 were written in the journal "Geochemistry" which and had an English version. But, as it turned out, the West these articles do not know, but if anyone read it, nothing about it is unclear.
According to Arlene Krotts, no one cited the work of the lunar soil, which was brought by "Luna -24" because that "what we do not know, for us there."
As said by Mr. Krotts, for soon there was significant progress associated with the assessment of the average water content in the lunar regolith: in 2006 in the West, the water content was postulated in a 1:1 000 million, but now, many scientists believe that the water in the soil more . This achievement is certainly valuable, but back in 1978 in the materials posted on the British language, it was suggested that the water content in the lunar soil is 1:1 000 …
But that's not all: the portion of samples brought back by "Luna-24", passed by NASA for future research. What happened to them — is an intriguing question. Of course one thing: Russian lunar science mission was not given an answer to the question of the existence of water in the lunar soil, despite the fact that the water content was measured, and then presented the global scientific community!
