Decisions Investment is selling Biosphere 2 which consists of 3.1 glass-enclosed acres and is located 16 miles North of Tucson, Arizona. 70 other buildings on the 140 acre campus are also up for sale. The site was most recently used for tourism.
8 "Biospherians" stayed in the self-contained environment in 1991 but their planned two year stay was cut short by numerous setbacks and rising costs. Over $200 million was spent to build it in the 1980s so it could be a space colony prototype.
Environmental features such as an ocean, rainforest, desert, etc, were inside the enclosed research center.
