Can humans live happily in space?

While most people consider Biosphere II a failure, it is good to remember
that in spite of making a lot of big mistakes, they were able to maintain
closure (or something very close) for over a year on the first try. That's
quite an accomplishment in my book.

It suggests that building closed biospheres is not all that hard,
particularly if emergency resupply is no more than a few days or weeks
away. In other words, colonies in Earth orbit should be able to run closed
biospheres with only the usual problems, not anything horrendous.
