Each year the analog astronaut community gathers at Biosphere 2 for the Analog Astronaut Conference to answer one simple question: how will we live and work in Space, the Moon and Mars?
Set against the backdrop of the incredible Biosphere 2 — the world's biggest ecological experimentation site — it is the first curated and entirely sealed off ecosystem, offering guests the experience to learn what it takes to run a habitat on the Moon or Mars.
“When we solve for Space, we solve for Earth” - Dr Sian Proctor - Inspiration 4 Pilot and Astronaut.
