The Grand Experiment

To test Biosphere II's ability to maintain a self-sustaining ecosystem in total isolation from the rest of the world, an eight-member crew was chosen to spend two years sealed in the facility. The four men and four women would produce their own food in the agricultural area, while at the same time monitoring their environment and carrying out a variety of scientific experiments.

After years of training and several shorter stays in the structure, the crew entered Biosphere II on September 26, 1991. Whether or not they could survive without outside assistance would determine the project's success or failure.
