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.
