Underwater station offshore at Key Largo Marc Reagan John Herrington and Nick Patrick unload dive gear.

After their return from a practice dive at the NOAA Aquarius underwater station offshore at Key Largo, Marc Reagan, John Herrington and Nick Patrick unload dive gear. Herrington is mission commander and Patrick is a member of the crew on the NASA Extreme Environment Mission Operations 6 (NEEMO-6) mission. Reagan is mission lead as well as underwater still photographer. The NEEMO-6 mission involves exposing an astronaut/scientist crew to a real mission experience in an extreme environment - the NOAA undersea station Aquarius offshore from Key Largo - to prepare for future space flight. Spacewalk-like diving excursions and field-tests on a variety of biomedical equipment are designed to help astronauts living aboard the International Space Station. Other team members are Doug Wheelock and biomedical engineer Tara Ruttley. To prepare for their 10-day stay, the team had dive training twice a day at the Life Support Buoy, anchored above Aquarius.
