Biosphere 2 – Where Science Lives

Once upon a time; there was an experiment to see if eight people could live inside a fully self contained structure that provided for all of their needs, for two years.  There were a lot of things they learned from it, but one of their major lessons was that they didn't know everything at that time that they needed to know in order to do it.

Just outside of Tucson is "Biosphere 2" a huge structure that contains within it several climate zones, and to which the children and I refer to as "Moonbase Earth."  

We had a great time exploring the Biosphere 2; it was a little hot, and I'm not fantastic at taking tours; but it's definitely a site to see!

I left thinking a lot about the 'failed' experiment, technology has come a long way in the last twenty years, they learned a lot from the first biosphere.  I wonder now if, using a lot less space, and a little more nutritional science, a self contained sustainable environment could be created that would succeed at the experiment if people could live for two years in health entirely closed off.
