That's a good point, but it doesn't address the possibility the "round earth" photo shots could have been constructed from inside a darkened Nasa space craft shot thru a round window with all the lights turned off within the space craft to make it seem like deep dark space.
I don't think those "space suits" the astronauts wore look capable of withstanding the temperature extremes which are supposed to exist on the moon either. It's funny we all drank that shitty orange juice substitute tang after the Apollo missions, but the technology for those extreme temperature high and low space suits never made it mainstream. I wonder why?
