About 45% of the lunar soil and rocks is made up of oxygenA pleasant surprise, thats exactly the same percentage as we have in our Earths rocks.
I know that NASA detected some Oxygen in the Moon rocks that were brought back. But its percentage amount was never mentioned as far as I am aware.
Apparently last, year Hubble looked at the Moon in Ultraviolat, and detected these oxygenated rocks, called 'Ilmenite'.
