I reckon as I’m guine to have to stop spittin’ in the ginrul direction of that there lunar orb, to avoid the inevitable consarquence of perplexifyin’ scientist fellers.
This is big news, whatever the source.
6 ppm isn’t very much. But in comparison, gold ore is commercially mined in quantities of around 1-2 ppm. And the cost of shipping water (or hydrogen and oxygen, aka rocket fuel) to the moon per pound is significantly greater than the price per pound of gold. This means that in theory extraction of water from lunar rock could be viable.
6 ppm is not a patch on the selipolar craters, which may have ores that are as much as 1/3 or even greater ice.
