U.S. researchers have found evidence of water on the moon by studying glass pebbles picked up by NASA astronauts more than 30 years ago. (article 1)
The study, published in Nature on Thursday, means " the presence of water must be considered in models constraining the moon's formation and its thermal and chemical evolution the abstract said. (article 1)
Most of the water in the magma vaporized into space, but traces may have drifted to the moon's cold poles, where they could remain as ice in shadowed craters. (article 1)
The glass beads from the magmas were bombarded with a stream of ions, and then the team analyzed the secondary ions emitted with a mass spectrometer. (article 1)
" We developed a way to detect as little as five parts per million of water said researcher Erik H. Hauri from the Carnegie Institution for Science. (article 1)
" We were really surprised to find a whole lot more in these tiny glass beads, up to 46 parts per million. (article 1)
" This suggests the very intriguing possibility that the moon's interior might have contained just as much water as the Earth's depleted upper mantle Hauri said. (article 1)
NASA, which funded the research, is planning to send the Lunar Reconnaissance Orbiter to the moon late this year. (article 1)
