Human Life Research on ISS Russian Segment

Sprut-MBI Experiment


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.

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.

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.
