But what mass fraction is that really? If it's only few ppm it won't affect structural applications.

- A_D_E_P_T 4y agoBack-of-napkin calculation suggests that it would be ~20 ppm if it were evenly distributed. But as any water is likely concentrated in surface rock and dust, it might be substantially more than that. Still, it may be possible to mine deep water-poor silicates and oxides and process them in a water-free hard-vacuum environment. Time will tell, I guess! Lunar fiberglass is still a highly speculative thing. (But extremely cool, at least in principle, due to its superlative strength and toughness.)
