Water has been definitively found on the Moon, Nasa has said, and there are a set of “water taps” that could hold it stably. They found water is present at high southern latitudes. The observations arose from something of a test observation, to see whether Sofia could examine the Moon. The flying observatory is usually used to look deeper into space, and it was not clear that it could even see the lunar surface properly since it is so close and bright. “It was, in fact, the first time SOFIA has looked at the Moon, and we weren’t even completely sure if we would get reliable data, but questions about the Moon’s water compelled us to try,” said Naseem Rangwala, SOFIA’s project scientist at NASA's Ames Research Center in California's Silicon Valley, in a statement. “It’s incredible that this discovery came out of what was essentially a test, and now that we know we can do this, we’re planning more flights to do more observations.” In the other study, Prof Hayne assessed a whole range of possible sizes for cold traps, down to one centimetre in diameter. The team found that small-scale micro cold traps - some just 1cm wide - are hundreds to thousands of times more numerous than larger cold traps, and they can be found at both poles. ... https://www.youtube.com/watch?v=FqSCqsExO18
