2006年VOA标准英语-NASA Technology Aids Water Purification Efforts(在线收听) |
By Paul Sisco Villagers in Iraq are better off today, thanks in part to NASA engineers from the Marshall Space Center in America's deep south. ------- Concern for Kids is a non-profit organization that has been operating in and around northern Iraq since 1992. President Todd Harrison learned of an urgent need for clean water in the village of Kendala, and he had an idea.
Volunteers from NASA went to Kendala. With help from citizens and U.S. Army personnel, they installed an adapted water pumping system, bringing safe drinking water to villagers for the first time in years. U.S. space engineers have been designing and improving a water and recycling system for shuttle astronauts and the international space station for decades. "The water recovery system developed for the international space system is a combination of a urine processor and a potable water processor,” Carrasquillo explains, “which takes the astronauts urine, and all the other waste waters that condensates from the atmosphere and recycles it to clean water.” NASA is completing an air and water recycling system for the space station that is about the size of two refrigerators. It is planned for installation in 2008. Developers say it will dramatically reduce the need for re-supply missions from Earth. |
