most of us are suited to space. nowhere in the solar system anywhere is as comfortable as the top of everest or the south pole. and so that's why i think the idea of mass emigration is a bit crazy. we have to bear in mind that space is not a place for human beings, except for adventurers, the kind of people who do go to the south pole and top of everest. what do the hera crew think about the experiment? well, we caught up with them, unsurprisingly out in the fresh air, shortly after they left the habitat. you know, we're all very similar. if we had one very extroverted person, maybe a strong personality that was slightly different than the group, that might have negatively affected the outcome. if you put four extroverts in there together, they're going to drive each other crazy eventually. maybe four introverts aren't going to be able to come together as a team as much, because they're more inwardly focused.
