NASA space psychology subjects ending 8 months of isolation

5. I don't think it's possible due to psychological obstacles

This is obviously just my opinion... I love the idea of exploring Mars, but I'm a realist and I think the assignment would be akin to torture after around 12 months (probably a lot sooner).

Second, it's going to be hard for NASA to find passionate, enthusiastic researchers with perfect, even tempered personalities that blend well with the other personalities (who are also OK with leaving Earth for 2+ years). I saw one article where they said extroverts could be problematic, but introverts could be too because they wouldn't have the alone time they need.

2 to 3 years in a confined space with the same people and no escape? Maybe sets of romantically compatible couples could work? Really, the focus might need to be on finding a faster method of getting to Mars to cut the trip time down.
