so to explain some of the science
every molecule emits a certain frequency of photons(certain colour of light) and knowing the exact colour of water means they can measure and monitor it.
they say they did not find any water in large blocks. definetly no underground lakes. no iceburgs, not even icecubes or puddles. so they are learning they cannot just tap into an underground aquifer, but instead have to mine it like mining gold dust spread out throughout the land.
so this is not going to be a 'well' type of mining mission. but a 'gold digger' type of mining
this then makes them able to plan what kind of mining operation to design for water capture on the moon
so that stops any hope of just tapping into a well and just setting up shop in one location. but instead have to move around and tap into multiple locations like quarry mining
their next hope is not so much a well that just sucks up the water. but instead hopes they can sort of 'frack' it out of the moons ground thus not having to shift as much dirt to get it
the amount of it (if all could be captured)... is about a standard serving can of cocacola per cubic metre
so a 3cubic metre (27x1cubic metre) will only gather 9 litres(if all can be captured) which would only be enough for 3 persons fluid use a day (2litre drink/ 1litre hygiene per person)
so i hope this can get some people to grasp the scale of whats needed to do to gather any reasonable amount to use for fuel/colonisation of the moon
