Scientists identify Earth-the equivalent amount of water in the Moon

There is no water in the Moon – so many, in fact, that in some places it is setting the amount of water within the Earth.

The origin of the scientific team searching including Brown University, the first measurements of the Lunar melt generalizations. These measurements show that certain parts of the CAP in the lunar calendar has water as a coat on top of the Earth.


A generalization of the glue pipeline are tiny moons of molten rock within the crystals trapped in volcanic glass deposits during outbreaks in the resulting explosion. A new search, published this week in Science Express, showing high content water from Lunar magma than previous studies have suggested a 100.


The result is the culmination of years of investigation by the search team and volatile volcanic glass that is returned by the Apollo program of NASA in the late 1960s and early 1970s. In the wild in 2008, the same group led by Alberto ??'????, Professor of Geological Sciences at Brown, reported the first evidence for the presence of water and models to assess the amount of water was originally in magmas before eruption.


"The bottom line," said ??'????, a writer on the paper check and primary investigator science bamhkr grant, "that in 2008, we have a water content of the primitive magmas moons should be similar to the water content where the topmost coat come poor planet. Now we have proof that he is indeed the case. "


New search received critical assistance to undergraduate mstodntit Brown, Thomas Weinreich, who found the exclusion list glue that allowed the team to measure the concentration of pre-eruption of water trend, to estimate the amount of water bapnim of the moon. With a needle in a Hay-it classic, Weinreich sought through thousands of grains from the famous high-Titanium "Orange earthquakes" discovered by NASA astronaut Harrison Schmitt during the mission Apollo 17 before finding the ten that melt generalizations.


"He just looks like a clear example with some black stains on the inside," said weinrich, the second author on the paper.


Compared to the meteors, the Earth and the other inside of our solar system contain relatively low amounts of volatile components in water, which were abundant in the inner solar system, during the formation of the Earth. Even lower than the amounts of these volatile elements found on the Moon long was claimed as evidence that you have established a huge following of high temperature, terrible. But this new research showing aspects of this theory must be reevaluated.


"Water plays an important role in determining the behavior of planetary surfaces sectorial, melting point of planetary interiors and location of the eruptive volcanoes planets," said Erik Hauri, geochemist with the Carnegie Institution of Washington and lead the research. "We can raise this is not the type of sample is more important than return to the Earth than those examples check out volcanic glass by explosive volcanism, not only on the moon have been mapped, but also throughout the inner solar system."


The research team measured water content of ion microprobe inclusions using state of art NanoSIMS 50 L.


"Unlike most volcanic online payments, including glue are encased crystals that prevent the escape of water vndipim during the eruption. These examples provide the best we have the amount of water in the Interior of the Moon, "said James Van Orman's case Western Reserve University, a member of the scientific team.


The research also adds a new twist on the history of water ice at the lunar poles who hmchtshim some recent NASA missions. The ice was attributed to the effects of the Comet, Meteor, but it is possible some of this ice water can be released by the eruption of magmas Lunar.


Malcolm Rutherford, the Emeritus Professor of Geological Sciences at Brown, also contributed to the paper. NASA Cosmochemistry and laser research funded, with additional support provided by the NASA Lunar Science Institute (NLSI) of the NASA Astrobiology Institute.
