Tired of the same-old Planet Earth problems? Perhaps you think it’s time to give another planet a go? But do you have what it takes for this distant quest? Nick Kanas’ Humans in Space, The Psychological Hurdles details the psychological and social issues of interstellar travel in the final chapter. Beyond the obvious loneliness and isolation of deep space, there are a few other things to consider:

Earth-out-of-view Syndrome. What would it be like to not just see Earth as a distant planet, but not see it all?

Monotony. How would you occupy your leisure time? There are no events to see, no relatives to visit, no sports nor Instagram feeds to follow. There’s nothing but the people and data on board. Does reading make a big comeback?

Physical Effects of Near-Relativistic Speed. What are the side effects of constantly travelling at a such a fantastic speed? Might we grow taller? Might the blood thin? The eyes cloud? And what of sleep?

Intolerance of Diversity. Most agree that some kind of group think is needed for such a journey to be a success. And so what of those that were outside the mindset? What about people who want to do things differently or maintain a belief outside of the norm? What would happen to them?

Justice. How would criminals and sociopaths be handled in such a small social network? How tolerant would it be possible to be of violent crimes? Is it one strike and you’re out?

Sex. How would people interact on a sexual level? Would birth control be required? Would monogamy be discouraged?

Mission Goals. How long would it take for the focus to sway from the original mission goal? What if a discovery were made of another possible planet on another course? Who would make these decisions? What authority would be needed?

Myths and Folklore of Earth: Earth will eventually become a memory. The second generation will only know it through stories and Disney movies. What effect will that have on how the society evolves?
