KENNEDY SPACE CENTER, FLA. - After their return from a practice dive at the NOAA Aquarius underwater station offshore at Key Largo, John Herrington and Tara Ruttley look over their dive gear. Herrington is mission commander and Ruttley, a biomedical engineer, is a member of the crew on the NASA Extreme Environment Mission Operations 6 (NEEMO-6) mission. 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 astronauts Doug Wheelock and Nick Patrick. To prepare for their 10-day stay, the team had dive training twice a day at the Life Support Buoy, anchored above Aquarius.
