London: Water found in ancient rocks on Moon may have actually originated on the early Earth and even survived the lunar-forming collision event, a new study suggests. The Moon, including its interior, is believed to be much wetter than was envisaged during the Apollo mission era. The study by Jessica Barnes and colleagues at The Open University, UK, investigated the amount of water present in the mineral apatite, a calcium phosphate mineral found in samples of the ancient lunar crust. "These are some of the oldest rocks we have from the Moon and are much older than the oldest rocks found on Earth, said Barnes. "The antiquity of these rocks make them the most appropriate samples for trying to understand the water content of the Moon soon after it formed about 4.5 billion years ago and for unravelling where in the Solar System that water came from," Barnes said.
