Water being inside of the Moon is the most wonderful discovery I can imagine, until something else brings me to en-wonderment. This means that life is possible, and this is exciting. We need to respect this discovery though, and understand that we cannot disturb yet another environment. Leave the Moon alone, do not destroy the Moon as well! We love the Moon! I am a Moon child as I was born in the month of June, a Cancerian, so much that my moods go with the tides of the Moon. Now knowing that there is water inside the Moon, I can say “no wonder I am so emotional!”
There is so much to discover, we have yet to even discover Earth and we are travelling on Mars now, just amazing! I have seen things in my time, but this is incredible, sorry I can’t stop! 🙂 There is a Lunar melt of some molten rock, which means that the Moons crust is very similar to a lot of the volcanic areas on Earth. This magma water that is created from the volcanic eruptions has a 100 times higher content of magma water, than previous studies have shown. Plus, this is not the only planet in the Star System that has water.
This can mean that there is life that is evolving on the Moon and has not yet created beings, or perhaps it already does. Hopefully we will find out what else is out there in the Galaxy. My husband and I are getting a beginners telescope, if anyone has really great suggestions for a home that resides in the city, with lots of light pollution. So if you know of any, let me know. NO ADVERTS PLEASE! Just suggestions! 🙂 Thanks and enjoy the article.
PROVIDENCE, R.I. [Brown University] — There is water inside the moon – so much, in fact, that in some places it rivals the amount of water found within the Earth.
The finding from a scientific team including Brown University comes from the first-ever measurements of water in lunar melt inclusions. Those measurements show that some parts of the lunar mantle have as much water as the Earth’s upper mantle.
Lunar melt inclusions are tiny globules of molten rock trapped within crystals that are found in volcanic glass deposits formed during explosive eruptions. The new finding, published this week in ScienceExpress, shows lunar magma water contents 100 times higher than previous studies have suggested.
The result is the culmination of years of investigation by the team searching for water and other volatiles in volcanic glasses returned by NASA Apollo missions in the late 1960s and early 1970s. In a paper in Nature in 2008, the same team led by Alberto Saal, associate professor of geological sciences at Brown, reported the first evidence for the presence of water and used models to estimate how much water was originally in the magmas before eruption.
“The bottom line,” said Saal, an author on the Science Express paper and the principal investigator on the research grants, “is that in 2008, we said the primitive water content in the lunar magmas should be similar to the water content in lavas coming from the Earth’s depleted upper mantle. Now, we have proven that is indeed the case.”
The new finding got a critical assist from a Brown undergraduate student, Thomas Weinreich, who found the melt inclusions that allowed the team to measure the pre-eruption concentration of water in the magma and to estimate the amount of water in the Moon’s interior. In a classic needle-in-the-haystack effort, Weinreich searched through thousands of grains from the famous high-titanium “orange soil” discovered by astronaut Harrison Schmitt during the Apollo 17 mission before finding ten that included melt inclusions.
“It just looks like a clear sample with some black specks in it,” said Weinreich, the second author on the paper.
Compared with meteorites, Earth and the other inner planets of our solar system contain relatively low amounts of water and volatile elements, which were not abundant in the inner solar system during planet formation. The even lower quantities of these volatile elements found on the Moon has long been claimed as evidence that it must have formed following a high-temperature, catastrophic giant impact. But this new research shows that aspects of this theory must be reevaluated.
“Water plays a critical role in determining the tectonic behavior of planetary surfaces, the melting point of planetary interiors and the location and eruptive style of planetary volcanoes,” said Erik Hauri, a geochemist with the Carnegie Institution of Washington and lead author of the study. “We can conceive of no sample type that would be more important to return to Earth than these volcanic glass samples ejected by explosive volcanism, which have been mapped not only on the moon but throughout the inner solar system.”
The research team measured the water content in the inclusions using a state-of-the-art NanoSIMS 50L ion microprobe.
“In contrast to most volcanic deposits, the melt inclusions are encased in crystals that prevent the escape of water and other volatiles during eruption. These samples provide the best window we have on the amount of water in the interior of the Moon,” said James Van Orman of Case Western Reserve University, a member of the science team.
The study also puts a new twist on the origin of water ice detected in craters at the lunar poles by several recent NASA missions. The ice has been attributed to comet and meteor impacts, but it is possible some of this ice could have come from the water released by eruption of lunar magmas.
Malcolm Rutherford, professor emeritus in geological sciences at Brown, also contributed to the paper. The NASA LASER and Cosmochemistry programs funded the research, with additional support provided by the NASA Lunar Science Institute (NLSI) and the NASA Astrobiology Institute.
