Moon's interior is likely 'very dry', claims new study
US-based scientists re-analysing a rock collected during the Apollo 16 manned lunar mission in 1972 have revealed that the Moon's interior is very dry. They claim the zinc on the rock's surface suggests it re-condensed after evaporating during the hot conditions of Moon's formation. Researchers would now study glass deposits, which in another study revealed that the Moon is "wet".
