Human Life Research on ISS Russian Segment

Biorisk Experiment


Objective:

Acquisition of new data on possible manifestations (boundaries) of phenotypic adaptation and genotypic changes in bacterial and fungus associations forming a typical microbiota of structural materials used in space technology.

Tasks:

Accommodation and exposure of Biorisk-MCH containers outside the pressurized compartment, and of Biorisk-KM sets and Biorisk-MCB containers inside the internal volume of the ISS Service Module.
Biorisk-KM trays are retrieved once a year, Biorisk-MCB and Biorisk-MCH containers are retrieved each half year.

Science Hardware Used:

Biorisk hardware including:


  • Biorisk-MCB Container.
  • Biorisk-KM Kit;
  • Biorisk- Kit;

Expected Results:

  • Prediction of resistance of space technology materials to microbiological factor and development of recommendations to mitigate the risk of microbiological damage.
  • Assessment of impact of cyclic changes of the Solar activity to characteristics of bacterial and fungus flora with regard to factors of phenotypic and genotypic variability, resistance factors and aggressive properties.
  • Assessment of fundamental capability to maintain viability of microorganisms on long-term space exposure (as compared with the Earth-to-Mars flight).
