Biosphere 2 was ambitious, and the first of its kind. The aim was to create a second, slightly more portable earth, a closed system you could put anywhere which would allow people to survive, growing their own food and living off of it even the oxygen was recycled. A totally closed experiment to test whether or not we could live on another planet.
The site is spread over 3 hermetically sealed acres with double airlocks for assured safety. Inside were replicated all the world’s necessary environments. A small ocean with a wave machine and beach, grassland savannah, tropical rainforest, farm and an additional mangrove wetland. Plants were chosen to remove carbon dioxide from the air and replace it with oxygen.
All 14 before the final selection
A group of fourteen people initially held a practice run. Each sported a fetching red jumpsuit made by the former maker of Marilyn Monroe’s dresses. Out of the group, eight were chosen for the full thing. A two-year stint in a completely closed system, just themselves and the farm, in a giant glass structure in the Arizona Desert.
8:15 am, 26 September 1991 all eight of the red-clad ‘bionauts’ climbed through the airlock, leaving behind them their recently consumed breakfasts and waving crowds. Behind them the airlocks closed and so began the $150 million experiment. Over the next two years the groups would survive together and be self-sufficient, exit only came for the ill. It was a bizarre affair.
Initially it was a media frenzy, Biosphere 2 was the first of its kind and tourists came by the busload to serve their voyeuristic needs, staring through the glass walls at the toiling human specimens held within. This activity itself went on to inspire a small cultural revolution, leading directly to the creation of Big Brother, an extremely popular Reality Show which let viewers in on the lives of ‘housemates’ who were people chosen to live in a house together and perform tasks. It is easy to see the similarities.
