Disbelief generator ? I guess the ancient egyptians had trubble with that one too BEFORE they build the pyramides ....perhabs Neil Armstrong also tried to turn it off just before the landing , but aparrently it got stuck on halfway , because a lot of young people today dosnt believe he ever made it to the moon . Sad .

The social problem is further complicated by the fact that human changes, and social structures must also change along with it. Your chosen crew may be fine with your plan at first, but would their children? Would their grandchildren? Would their grand, grandchildren who by this time probably have no idea what their mission means anymore? What works for one generation may not carry over the next, sometimes changes are needed within even one generation. You may have an extremely good leaders on one generation, but you might have a bad one the next. You may have good crew that contribute to the survival and success of mission, you may have dissentients and saboteurs that ruin the whole thing. Your system must somehow limit the harm of the bad elements, support the good, maintaining is functionalities no matter how much changes it has to endure.

That's actually a deep and meaningful description of human civilization on Earth too.
