Concordia Research Station, Dome Circe, Antarctic Plateau, Antarctica

Concordia Station shares many stressor characteristics with long duration deep space missions, in particular extreme isolation and confinement, and as such serves as a useful analogue platform for research relevant to space medicine. During the winter the crew are without possibility of evacuation or deliveries for 9 months and live for a prolonged period in total darkness, at altitude almost equivalent to 4000m at the equator. The physiological and psychological strains on the crew are marked. Concordia station is particularly useful for the study of chronic hypobaric hypoxia, stress secondary to confinement and isolation, circadian rhythm and sleep disruption, individual and group psychology, telemedicine, and astrobiology. Concordia station has been proposed as the one of the highest fidelity real-life Earth-based analogues for long duration deep space missions.
Glaciology
In the 1970s, Dome C was the site of ice core drilling by field teams of several nations. In the 1990s, Dome C was chosen for deep ice core drilling by the European Project for Ice Coring in Antarctica (EPICA). Drilling at Dome C began in 1996 and was completed on December 21, 2004, reaching a drilling depth of 3270.2 m, 5 m above bedrock. The age of the oldest recovered ice is estimated to be ca. 900,000 years.
