Disembarking from the boat are Otto Rutten and Marc Reagan mission at the NOAA Aquarius underwater station offshore.

Disembarking from the boat in Key Largo are Otto Rutten and Marc Reagan, participating in the NASA Extreme Environment Mission Operations 6 (NEEMO-6) mission at the NOAA Aquarius underwater station offshore. Rutten is director for the National Underwater Research Center; Reagan is mission lead. The NEEMO-6 mission involves exposing an astronaut/scientist crew to a real mission experience in an extreme environment 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. The NEEMO-6 team comprises astronaut John Herrington, mission commander, astronauts Doug Wheelock and Nick Patrick, 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.
