text: For the beliefs that the fog that appeared in another photo was due to alien activity; fog happens on Earth too. If we take this even farther, it could have just been that the lens were fogged up, or the area was getting something like precipitation. I do not know for sure, but NASA has been said to have some of the most high quality equipment. I am more willing to believe that it is a fog and not a problem with the equipment (7). Although anything could break at anytime, I beileve that the fog was just a natural thing and not something overall crazy.
