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 second mission of Biosphere 2 was ended prematurely in September 1994 due to internal disputes regarding the facility's management and finances.1
Following these conflicts, the property's ownership structure changed when Decisions Investments Corporation gained complete control of the project, subsequently leading to the decision to lease the facility to Columbia University for use as a research institution.1
