Nonesense. The technology exists, and has done for a long time, that allows NASA (or any other governmental organisation for that matter) to produce any digital image they like, and pass it off as genuine.I've seen technology that can take a photograph of your face, and re-create the three dimensions of your head very, very acurately. Not to mention the fact that this same software can be used to manipulate any image, into anything they like. Remember the Oswald picture shoing Lee Harvey holding a gun and pamphlets? That's old school, what they have nowadays is much more sophisticated and would allow them to strip Oswald down to his trunks, put him in a swimming pool, or piloting an aircraft... it is very powerful technology. It is not used for entirely honest purposes, but that's the way these people think these days. Not to mention the fact that this is not just for manipulating images of people...Therefore it would be rather easy for them to take any image beamed back from Mars, and manipulate it to hide, or even show, anything they wanted.Just food for thought - what if the 'artifacts' we all see in the Mars images are placed there because 'they' want us to see them? What if the artifacts are generated in order to hide what might really be there?Fin.Sorry, to put a dampner on your 'parade' there, but I felt you should know.
