Scientists believe the Moon is wet inside
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.”
