SCIENCE HARDWARE USED:

• Sprut-K Kit to determine different human liquid volumes by measuring the impedance of the body and its segments.
• Body mass meter with a range from 50 kg to 100 kg with an accuracy of ±0.25 kg.
• Hematokrit microcentrifuge to separate plasma from erythrocytes.

FLIGHT EQUIPMENT USED:

• Laptop.
• Power supply unit.

OBJECTIVE:

Investigation of a state of human liquid media, assessment of adaptation mechanisms and prevention of unfavorable impact of zero-gravity on the hydration status and post-flight orthostatic tolerance.

TASKS:

Determination of volumes of intracellular and intercellular liquid, body's total liquid, circulating blood and relation between cellular and liquid blood component.

EXPECTED RESULTS:

The dynamics of a hydration status of a cosmonaut will be first investigated, including analysis of Homo's separate liquid regions in space flight conditions.
