As capt says it can’t be water because that’s not news.

I half-expect NASA to make a non political announcement on behalf of Trump's re-election campaign.

I fully expect NASA to try to secure funding by bigging it up.

Maybe the discovery of the cow that jumped over or Michael Jacksons ghost walking around backwards......or is it forwards

Hidden pockets of water on the moon could be much more common than scientists previously thought, and the discovery could have potential implications for future lunar missions. Researchers suggest that in some cases, tiny patches of ice might exist in permanent shadows no bigger than a coin.

Cue jokes re: Irish Water are planning a mission to the moon, as it's easier than fixing our existing network

New Scientist: But it still isn’t clear how stable water in this form is over long periods, says William Bottke at the Southwest Research Institute in Colorado. “Astronauts might also have great difficulty extracting this water,” he says. “For example, to fill up a bottle, the astronauts might need to process thousands of kilograms of rocks.”

The NASA press release says that within Clavius crater they detected "water in concentrations of 100 to 412 parts per million – roughly equivalent to a 12-ounce bottle of water – trapped in a cubic meter of soil spread across the lunar surface ... As a comparison, the Sahara desert has 100 times the amount of water than what SOFIA detected in the lunar soil".

12 US fluid ounces in a cubic metre is about a litre per 10 tonnes of lunar soil. On the other hand, lunar rocks and soil are about 45% oxygen by weight. If you have the energy to do it you can make 9 litres of water for every kg of hydrogen you transport to the moon. That could be done with solar energy anywhere on the sunlit surface. Intuitively it sounds much more viable than water extraction, but you'd have to run the numbers including the cost of payload to the moon.

So, not very newsworthy except maybe for China. The new lunar base could be a giant prison with chain gangs breaking rocks and living on a teaspoon of water per day.

Processing won't be easy. For these reasons, we conclude that the water we observe is trapped within impact glasses.

The water is also so diffuse that it's in neither liquid nor ice form -- you are talking about scraping individual molecules off dust grains.
