They found up to 50 parts per million of water trapped in tiny spheres of volcanic glass.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://space.newscientist.com/article/mg19926644.200-now-the-moon-reveals-its-water.html?feedId=online-news_rss20"><P>That's not much compared with the 500 to 1000 ppm of water in Earth's mantle. Yet when the lava erupted some 3 billion years ago it was exceedingly hot - perhaps up to 7000 °C - so most of the water initially present would have diffused out of the magma, leaving only a small amount by the time it cooled.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://space.newscientist.com/article/mg19926644.200-now-the-moon-reveals-its-water.html?feedId=online-news_rss20"><P>They concluded the moon's mantle has between 260 and 700 ppm of water. "This is very surprising, because for 40 years people have studied lunar rocks and no one found any water," says Saal.
