Biosphere 2, Artificial biosphere in Oracle, Arizona
The facility spans 3.14 acres and contains multiple enclosed ecosystems, including a rainforest, ocean, desert, mangroves, and savanna environments.
Construction completed in 1991, the research station housed eight scientists for two years to study closed ecological systems for potential space colonization.
The research center contributes to environmental education through programs targeting students, researchers, and visitors interested in climate change and sustainability.
Visitors can explore the facility independently using a mobile application that provides information about ongoing research and ecological zones.
The agricultural section produced 83 percent of the food needed during the first mission, including bananas, papayas, and sweet potatoes.
