Aquanauts splash down
The NASA Extreme Environment Mission
Operations (NEEMO) 21 mission was conducted this summer as an international crew
of aquanauts splashed down to the undersea Aquarius Reef Base, located 62 feet
below the surface of the Atlantic Ocean in
the Florida Keys National Marine Sanctuary.
The NEEMO 21 crew performed research
both inside and outside the habitat during
the 16-day simulated space mission.
