If NASA chose you for a special mission to another solar system, how long would it take for you to succumb to space madness?

Having astronauts who will keep their cool is a concern, Jules Suzdaltsev reports for DNews. Being isolated for a long period of time, such as in the confined area of a spaceship, could lead to depression, among other issues. Suzdaltsev specifically refers to something called the “third-quarter phenomenon,” in which people crack under the pressure following the halfway point of their trip — after the excitement of their journey turns to boredom, they may become aggressive.

Although there are certain personality traits that may lend themselves well to space travel, such as independence, sensitivity to the feelings of others and being goal-oriented, it’s possible that “coping mechanisms people normally use back home may not transfer to space,” Suzdaltsev says.

When Russia, China and the European Space Agency sealed people in a habitat for 520 days, they encountered sleep issues such as deprivation and an irregular circadian rhythm, as well as depression, boredom and team cooperation problems.
