BIOSPHERE 2 INSTITUTE

The Biosphere 2 property was originally part of the Samaniego's CDO Ranch, a homestead in the 1800’s. After several changes of ownership, it became a conference center in the 1960s and 1970s, first for Motorola, then for The University of Arizona. Space Biospheres Ventures, bankrolled by Bass, bought the property in 1984 and began construction of the current facility in 1986 to research and develop self-sustaining space-colonization technology. Two missions, between 1991 and 1994, sealed Biospherians inside the glass enclosure to measure survivability. Behind this highly public exercise was useful research that helped further ecological understanding.

The property was sold in 2007 to CDO Ranching and its development partners. The enclosure now serves as a tool to support research already underway by UA scientists. As a laboratory for big-scale projects, the university’s stewardship of Biosphere 2 will allow the UA to perform key experiments aimed at research, outreach, teaching and life-long learning about Earth, its living systems, and its place in the universe.

This tour is approximately 5 hours and is inclusive of round trip transportation, admissions where applicable, bottled water on board, and a JW Marriott Starr Pass Destination Services Guide throughout. This tour is a rain or shine event.
