Biosphere 2 was built between 1987 and 1991 as a way to test the viability of closed ecological systems and human life in outer space. The tests were held twice in the early 1990s.
Last month, Biosphere 2 was used to test what living in a habitat on another planet might look like.
The facility is owned and operated by the University of Arizona in Tucson.
