Sheyna Gifford spent a year living on a volcano in Hawaii with just five other people as part of a NASA project to simulate life on Mars. Living in a biodome the size of a two-bedroom apartment, the crew studied the psychological effects and group dynamics that could be at play when astronauts eventually make it to Mars.

This interview — about relationships, food and free time while in isolation — originally aired on Nerdette back in 2017, but it also has a few interesting parallels to our collective situation during the 2020 coronavirus pandemic. Plus, Sheyna assigns us some truly excellent homework, about why you should think very carefully about who and what you want on your spaceship.
