Biosphere 2: A Faulty Mars Survival Test Gets a Second Act
Produced by Joshua Fisher
Biosphere 2 was a vast, greenhouse-like structure that replicated the ecosystems of “Biosphere 1” –- Earth. The inhabitants called themselves “Biospherians,” and dressed in Star Trek-like uniforms promised not to emerge for two years.
The $150 million experiment aimed to collect data with an eye to building structures to colonize space. But it quickly went awry, and led to many questions. Was this really science? Or just science fiction?
Twenty years later, the dreams that gave rise to Biosphere 2 continue.
