Sci­en­tists be­lieve the Moon is wet in­side

The Scotsman - - News Digest - By JOHN VON RADOWITZ

An­cient vol­canic de­posits strewn across the Moon show signs of large amounts of wa­ter trapped be­neath the lunar sur­face, say sci­en­tists.

The ev­i­dence sug­gests that at least some of the Moon’s man­tle – the rocky layer that makes up most of its in­te­rior con­tains as much wa­ter as its Earth coun­ter­part.

Trace amounts of wa­ter were found in vol­canic glass beads brought back to Earth by the manned Apollo 15 and 17 mis­sions in the early 1970s.

The new re­search in­volved an or­bital spec­troscopy anal­y­sis of light re­flected from de­posits left on the Moon’s sur­face by vol­canic erup­tions.

It re­vealed a strong wa­ter sig­na­ture, in­di­cat­ing that the in­te­rior of the Moon is far wet- 0 Ralph Mil­liken said sam­ples sug­gest the in­side is wet ter than had pre­vi­ously been thought.

Lead sci­en­tist Dr Ralph Mil­liken, from Brown Uni­ver­sity in the US, said: “The fact that nearly all of [the sam­ples] ex­hibit sig­na­tures of wa­ter sug­gests that the Apollo sam­ples are not anoma­lous, so it may be that the bulk in­te­rior of the Moon is wet.”
