Apollo Moon Rocks: Dirty Little Secrets

The problem with this article is that it doesn't identify any mystery that's of use to conspiracy theorists. The contaminants in question are materials that the samples would have come in contact with during their collection, packaging, and transportation by Apollo astronauts, and during subsequent handling by LRL staff. It doesn't raise any issues that contradict advertised Apollo procedures.

It's all about falsifiability (in the epistemological sense). If you want to argue that the samples were textured by shooting substances at it, you have to show evidence of that substance, and also show that the presence of that substance can't be explained by anything reasonably arising out of the Apollo procedures. If all you have is something that can be explained either by a hoax theory or by the accepted Apollo story, then you have nothing. You can't texture a rock by shooting Teflon at it.
