The Main Goals of Biomedical Research at Antarctica Vostok station
Study of adaptation, functional disorders and possible illness during one year living in extremal environment
Test advanced methods and tools for profilaxis and treatment of disorders and illness
Сommon Risk Factors for Health in Antarctica / Vostok station / and Space
Expedition
Social and information isolation AutonomousSmall size of stationHypokineziaLimited amount of crewmembersMonotony of lifeTinned foodChanged gas environment at the stationExtremal low temperatures outside the stationChanged magnetic environmentUnusual photoperiodic /day – night Necessity of put on special clothes before going outside the station
The Psychic State of Polar Man by Self Reports, Medical Observations and
EEG Records
Duration of expeditions,
monthsSymptoms EEG
1 - 2 High spirit, increased general activity, high capacities for work
• Increased spike- activity
• Increased alfa- and beta - activities
• Increased frequency of alfa - rhythm
3 - 4 Lowering of general activity and spirit, high irritability and conflicting, signs of asthenia
• Disappearance of spikes
• Lowering of beta - rhythm activity
5 – 6 Unstable spirit, high irritability, need for more frequent change of activity
Increased delta - activity

Records
Duration of expeditions,
monthsSymptoms EEG
7 - 8 Improvement of spirit, high conflicting and agression,
decreased capacities for work, lowered interest to usual duties,
asthenia
Increased teta - activity
9 - 10 High spirit, elevated touchiness and aggression, reticence, low interest
to external events
• Increased beta - activity• Spikes
• Decreased delta - activity• Increased amplitude of alfa-
rhythm
11 – 12 High spirit, increased general activity, high irritability and conflicting, lack of restraint
• Lowering of alfa - activity and frequency of alfa - rhythm
• Decrease of beta- and delta – activity

Astrobiology in Antarctica
To discover form of life in soil and ice-covered lakes assuming that the same forms can exist on the Mars surface
To test the technology and hardware developed for using it on the Mars surface
Some results of research/Victoria Land of Antarctica/
The ice-free dry valleys Authors
1. Algae Horowits N.D. et al., 1972
2. Imperfect yeast Cryptococcus vishniaci
Vishniac H.S. and Hempfling W.P., 1979
3. Cyanobacteria and lichens Fridmann E.I., 1982
Perennially ice-covered lakes
Cyanobacteria and Diatomere Simmons G.M. et al., 1981
GENERAL CONCLUSIONS Central Antarctica, dry deserts and iced covered lakes of Antarctica are the proper natural Mars analogs for research in space life sciences
In spite of many extremal factors of prolonged living at Vostok station the most significant factor for wellbeing is isolation of small group in limited space
The psychophysiological research is the most priority biomedical research during prolonged living in extremal environment
The atmosphere with low barometric pressure (≈460 mm Hg) and low partial pressure of 02 (≈90 mm Hg) may be used as basic or accident atmosphere for orbital space and planet ary stations
