NEEMO -- the NASA Extreme Environment Mission Operations project -- sends groups of NASA employees and contractors to live in Aquarius for up to three weeks at a time. For NASA, Aquarius provides a convincing analog to space exploration, and NEEMO crewmembers experience some of the same tasks and challenges underwater as they would in space.
Like the environment of space, the undersea world is a hostile, alien place for humans to live. Far beneath the waves near Key Largo, Fla., an underwater laboratory called Aquarius provides a safe harbor for scientists to live and work for weeks at a time.
