Biosphere 2
Biosphere 2, located in Oracle, Arizona, U.S., shown in 2008. The facility was originally developed to study survivability and assess whether humans were capable of building and living in self-sustaining colonies in outer space. It was later used as a scientific research facility.
The first survivability mission in Biosphere 2 began on September 26, 1991, when a crew of eight individuals was sealed inside the facility to study the feasibility of self-sustaining colonies in outer space.1
