"The total amount of H2O released during the emplacement of the mare basalts is nearly twice the volume of water in Lake Tahoe," said Needham. "Although much of this vapor would have been lost to space, a significant fraction may have made its way to the lunar poles. This means some of the lunar polar volatiles we see at the lunar poles may have originated inside the moon."


What are the implications from this for lunar research? Could examination of the poles unlock more secrets of the Moon's past compared to other areas? Which would be the most interesting areas to investigate, for geological purposes?
