Recent space.com article describes H2O detected in Apollo samples of volcanic glass beads:
http://www.space.com/scienceastronomy/080709-moon-water.html The authors estimate this implies a concentration of 260 ppm H2O in the lunar magma. [The article states this is close to the level of H2O in some Earth magma environments] -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

Well, it makes a certain amount of sense. If the Moon was created in the Big Whack, you'd have to think that the bodies involved (proto-Earth and the impactor) would have a fair amount of water built up already. I always found it unsatisfying to believe that *none* of that water would end up in the mass that accreted into the Moon. Small amounts, to be sure -- but I always felt that *some* water ought to have been incorporated.
Seems my gut-level feeling was correct. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
