I'm trying to track down the source of this image so that I can get a hi-res version.
The image is shown in some news stories about the amount of helium 3 that is on the surface of the Moon. The red indicates the highest concentrations
of the element.
Links to several stories that have this picture.
I may have missed something in the articles, but I can't find a link to the original.
Here's an interesting note from one of the links.......
How much Helium-3 is on the Moon?
To extract one ton of helium-3, it is estimated that 200 million tons of lunar soil would have to be processed [in helium-3 rich regions of the
Moon]. That is equivalent to mining the top 2 meters of a region 10 kilometers square.
Sounds like a lot of work for a little helium-3.
Any large scale extraction of helium-3 would require a large area to be striped away and processed. That would leave a significant scar on the surface
of the Moon just like strip mining does on the surface of the Earth.
And this kind of mining requires very large equipment and processing facilities that should be clearly visible from orbit.
All of these things would be very hard to hide because it must be done on the surface. The helium 3 is only in the top layer of the Lunar regolith, so
a base underground would have no access to the element at a deeper level.
If anyone can nail down a hi-res version of the top picture I'll do a complete search of the red areas with World Wind to see if I can find anything
obvious in the areas marked in red.
P.S. - I wanted to correct my earlier comment about deuterium on the Moon.
I stated that the Moon lacked any deuterium, but on further examination, there is some quantity of deuterium on the Moon. I'll try to find out how
