That first link can be shot out right away, since it's from NASA, who organised the 'landing' to begin with. And asuming no one would've been to the moon before that, how would they know the properties of moon rocks and dust?
About their excuse for the stars not showing up... Rubbish. I could take an old, black and white camera outside right now, take a photograph of the sky, and I'd be able to see the stars. If anything, the stars would appear brighter than regular (Asuming the lens wasn't polarised).
