The state of water on the MoonLink here. The article describes new research that suggests the ice thought to exist in the Moon’s permanently shadowed polar craters is constantly being reworked, with some being leached away as other processes (comets, solar wind) replenish the losses.
They also theorize that this process might be making it easier to reach that water.
For forthcoming science and exploration, the scattering of water particles could be great news. It means astronauts may need not to subject themselves and their instruments to the harsh environment of shadowed crater floors in order to find water-rich soil — they could just find it in sunny regions nearby. “This research is telling us that meteoroids are doing some of the work for us and transporting material from the coldest places to some of the boundary regions where astronauts can access it with a solar-powered rover,” Hurley said.
To put it mildly, there is a lot of uncertainty about this last conclusion.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

I believe the statement of meteor impacts spreading water to other locations causing the moisture to boil away and sublimate deeper into the lunar regulith soil in easier to find locations it’s probably a sound theory that can be easily verified with a drill. It could result in just a trace, or an entire frozen world covered in meteorite dust under the surface…
If true, a bulldozer could push the top few inches exposing heat to the permafrost allowing the moisture to sublimate to the nearest insulated cold spot.
The permafrost could be mined, scooped into a closed system hotbox were the frozen gases will boil and be 100% recovered returning the dry dirt to the hole.
