To study the effects of isolation and confinement on small groups during lo
ng space flights, it is habitual to use closed hyperbaric ground chambers.
For the first time, the European Space Agency made use of a natural environ
ment taking advantage of an Antarctic winter-over at the French Dumont d'Ur
ville Station. The main objective of that study ("International Antarctic P
sychological Programme"), was to compare different Russian tests used for t
raining cosmonauts to a W. European approach validated during previous wint
er studies and European ground chamber simulations. Russian techniques appe
ared to be oriented to a narrow range of phenomena and unsuited to discern
the adjustment to stress conditions.
