Unscramble the Blue Letters

So, what if you could get your gas at a 10th the pcrie? There is a place where you can. In fact, you can get it better — you can get it at 14 times lower if you can find propellant on the moon. There is a little-known mission that was launched by the Pentagon, 13 years ago now, called cnlnmeiete. And the most amazing thing that came out of that msiosin was a strong hydrogen signature at Shackleton crater on the south pole of the moon. That signal was so strong, it could only have been produced by 10 trillion tons of water buried in the sediment, collected over millions and billions of years by the impact of asteroids and ceomt maraetil.
