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.

Recycling water in the area.

 Kits forward osmosis six will fly aboard space shuttle on mission in STS-135 credit: NASA/Todd Mortenson during the last flight of Space Shuttle astronauts will test a new method for Recycle Bin, use water, water is important for life and have access to water, Earth is a major obstacle for future space exploration .

Water-it is important for life. When they surveyed the area in the future, venture beyond low-Earth orbit. Their only tap is on board their spacecraft during possible flight thaikrasuai NASA scientists plan a test new methods for recycling "used" astronauts in microgravity.


The idea is to make the fortified beverages, hydration and ovaries from all data sources that are available in a foreign spacecraft, and even urine. How to set up for testing using a process called forward osmosis.


"Forward Osmosis are scattered in the nature of the water through a semi-permeable membrane describes Michael Flynn research scientist at NASA's Ames Research Center" membrane action as a barrier that makes small molecules such as water. To pass through while larger molecules, such as salts, sugar starches William virus bacteria and parasites block. "


How to forward osmosis and then used for the application of pure water, earthbound does know change into water drinkable in six to eight hours using a bag containing two separated number ngom. With membrane allows technology partners help in a variety of settings from outdoor sports, such as looking for the soldier. Natural disaster that purify water is important for survival.


Membrane alone can work for most of the water, but the two phases are necessary when recycling urine. It must first be filtered using bed activated carbon, which removes urea and alcohol is through tissue alone.


Scientists from NASA's Kennedy Space Center in Florida, plans to test models of altering your bags aboard space shuttle on in between STS-135 mission this summer by Kennedy brought NASA Project Manager Woodward Group included Spencer in the transport of shuttle type install six forward osmosis free bag for astronauts to test the manufacturer of innovative technology Hydration bags of Albany Ore to make a few adaptations. became a commercial product for spaceflight.


"It was the same membrane, but Tung is out of the plastic remanufactured is ' off ' gas or by writing," said Woodward description initiatives that have been changed to a quick version used in the area to make it easier for the astronauts to operate in weightlessness.


The test will come the end of the mission STS-135 after release from the International Space Station astronaut has a shuttle to injection mixture liquid concentration below contains a dye as an external Chamber of the engine, which represents the water of "dirty" prepared. He then has a higher concentrated "drawing." The tower solution in your pocket. Repeat the process for the sum of the six bags.


"Some of the unknowns. If you have eaten and fluid in the area, it can cause bubbles instead of liquids. So, what does that follow the peg on membrane said Woodward "will it still draws through tissue like in 1 g.


The plan includes astronaut massage and manipulate 3 bag to help in the transfer of liquid through a membrane to see whether it helps in the process work better in the absence of gravity.


"The test that we will see the effects of mechanical mixing on a membrane as far as he is about to increase the rate of flux half of them are going to get shaken and kneaded tools a few minutes. Describes the project engineer Monica Soler working under service contracts with the engineering team QinetiQ North America.


Soler said the combination of help and hope that the application is long term in a spacesuit that induce mixed mechanical as astronaut move around during spacewalk.


Comment test after five hours. Crew members, for example, syringes are used to connect to the Chamber within each bag and remove 60 milliliters of samples from each of the six bags and stow them for landing. When the sample is returned to Earth aboard Atlantis. Project scientist Dr. Howard Levine and Dr. Michael Roberts from the Kennedy Space Life Sciences Lab performs post-flight analysis of the example to see osmosis working in microgravity forward?


The results could prove that the device can have multiple applications for NASA spacesuits than it could be an emergency backup water source for the International Space Station, hydration and nutrition during an emergency situation back to the world as well as help during long-term space exploration in the future.


In addition, water recycling Results from the tests can shed light on several other aspects of life in the area.


"Forward Osmosis process is responsible for the absorption of nutrient in water from human intestines into the blood. It is a process that allows the plant root zone water from soil. Describe flynn "in addition, many drug delivery capsules used forward osmosis." Learn how forward osmosis weightlessness affected may, scientists are looking into zero gravity's effect on plant growth space and gastrointestinal function of humans in all areas-that might help future space travelers adjust better in long duration missions.


Therefore, in most This simple device tests, one during the last day of the departure end of the shuttle could provide important information for future exploration beyond our planet.
