Serious lockdown viewing

To have a research station on another planet, we have to figure out how to recreate a tiny biosphere for humans. That’s what the Biosphere 2 project in Arizona was trying to do in 1991. I was so interested in this experiement that I spent time locked inside their test module. But this $150 million structure was built by a theater group instead of scientists, and therein lies the drama worthy of a film. Skip the comedy (Biodome, 1996) and watch Spaceship Earth (2020), a new sympathetic documentary on this remarkable project. What they learned, of life support and human dynamics, should be better known. (Imagine being really locked down for 2 years.) Streams on Hulu, Amazon. — KK
