The worst problems with long-term spaceflight are not technical

In scientific and fictional books and writings and films, the problems of the long-term spaceflight have been mentioned the technical and physiological problems, like long-term staying in the zero-gravity would make muscles so weak that the astronauts cannot walk on the destiny, and that thing causes many dangerous visions.

What if they would be too weak to climb up the stairs with their spacesuits, or those suits would be too heavy anyway. The worst problems are social, and the biggest question is, what happens if somebody would get angry?

Or what if somebody gets hurt? What if some member of the crew is the wrong choice, and that member of the crew starts to cheat other members? When the spacecraft would travel between Earth and Mars, there is no way to take control of the situation, if somebody would start to act dangerously? What would those people do in that case?

There have been some horror stories, which are located in the space, and one of the most horrific scenarios is that, what if there would be a serial killer in the crew. In that case, the flight control must just decrease the gas pressure, that all the crew members would get unable to operate, and the craft would remote controlled back to Earth.

But there is another version of this kind of problem, and that is, what if some crew member would not dare to land to another planet? Or how the administration will recruit a member of the team, whoever lands to another planet? How to tell that person, that the role is vital, but there is no glory? That there would not any public question about that member of the team.

This kind of thoughts has raised in my mind one question about the social tests, what are made in the closed environment. That is "how realistic those experiments are in the real-life"? Would the test controllers tell those members of the test team, that their family members are dead if some kind of accident would happen? Or would the commanding team of the Mars-flight tell that thing to crew member, if that kind of sad thing will happen?
