When you lock a bunch of humans in a small space for a long time, they can go a little crazy. So researchers from the Australian National University are trying to understand the dynamics that might afflict a long-term space mission, and offer some solutions to make things easier. Volunteers from the Mars Society will travel to the Australian desert, and attempt to mimic some of the conditions experienced by long-duration space travelers. The researchers will test them daily, and watch for detachment, disagreements, and see if the larger group will splinter off into smaller subgroups.
