Its an interesting idea but I wonder if they have considered that if there is indeed water under that moon dust layer that it might evaporate once exposed . It would be strange twist of fate if the only water on the moon evaporates in the name of science. Just saying.
Ever have the feeling that some people with letters after their names like PhD or MDS have waay to much time on their hands?
no.. certainly not in this case... this comment suggests that perhaps you don't understand the ramifications of finding water on earth's moon ?
