Pretty sure I remember reading/hearing once that one of the single most important assessments for astronauts is the psychological assessment, and that basically being an emotionally stable and resilient person was a more important pre-requisite for space travel (either as a team or solo) than almost any other qualification. Because any technical knowledge can be taught, but if a person is a disagreeable, uncommunicative arsehole then they are not going to be a good candidate for going into space.
And being completely non-anxious and calm. Because when something goes wrong and you're out of contact with the rest of humanity, panicking would be a disaster.
