Has anyone already tried living underwater?
Diving pioneer Jacques-Yves Cousteau built the first inhabited underwater habitat in 1962. Called Conshelf 1, this steel cylinder was home, for a week, to two divers. They were submerged off the coast of Marseilles at a depth of 10m, studying marine life and even building an underwater farm.
Underwater living isn’t just for oceanographers, though. In 1970, an all-female team of US ‘aquanauts’ spent over 10 days 15m underwater in the Caribbean. The aim of the mission, called Tektite II and part-funded by NASA, was to study the psychological effects of living in close quarters, in an environment similar to that of a spacecraft. Nowadays, there are a handful of underwater research labs around the world.
