A long time ago on this board's predecessor, we had a discussion of how, with what we know, would we have pulled-off a moon-landing hoax. To put it another way, what would the historical record look like if it WAS hoaxed.
The answer was, "nothing like the historical project."
Some key points:
- Military oversight (i.e. no NASA)
- "Skunk Works" spacecraft development ("Can't risk the Russkies getting this technology.")
- No television ("We'd have to develop special light-weight cameras. Not gonna happen.")
- Photography limited to just a few images (if any - "The radiation fogged the film. Sorry!")
- Only one mission ("Too dangerous - These guys barely got back alive.")
- No returned samples (The chance of space-germs not worth the risk)
- No continuous telemetry or voice link
- Encrypted comms
- Limited press access to the astronauts
- No press access to Mission Control
...and that's just a few things needed, because every public opening (photo, communication, test, etc.) is an opportunity to screw-up and get caught.
