Human Life Research on ISS Russian Segment

Rastenia-2 Experiment


Researches aimed at solving the problems of fundamental biology and problems of optimization of plants cultivation modes for future greenhouses as part of advanced space life support system.


  • Mounting and preparation of equipment for experiment performance.
  • Study of specific features of water-air mode of the Lada greenhouse vegetation vessel in space flight conditions
  • Study of plants cultivation technology ("Mizuna" lettuce, "Micro-Tom" dwarfish tomatoes, dwarfish (red) pea) as applied to standard greenhouse devices
  • Study of the impact of space flight factors on the growth and evolution of plants which can be potentially used in space vitamin greenhouses
  • Study of germination and viability of plants
  • Study of phenology of plant evolution
  • Study of reproductive property of plants and production of the second generation of space seeds
  • Study of chemical composition of plants and seeds grown in zero-g conditions to define the content of nitrocompounds in vegetable biomass
  • Determination of ethylene concentration in the ISS RS atmosphere

Science Hardware Used:

  • - Lada greenhouse consisting of:
    - Control unit;
    - Lighting unit;
    - Leaf chamber;
    - Root module;
    - Water canister.
    Being a module-type system, the Lada greenhouse ensures maximum flexibility, its dimensions are decreased by four times as compared to the Svet similar greenhouse used on board the Mir OC.
  • Accessories Kit.

Flight Equipment Used:

  • Water canister
  • SVO-3V receiving device
  • Video camera SONY DVCam
    for video recording of the process of crew operation with the greenhouse.


  • Rasteniya Kit to return plant samples to the ground
  • Video tape

Expected Results:

Assessment of productive properties of leaf vegetable plants in zero-gravity conditions and verification of land treatment to extend the closed ecological life support system techniques to spacecraft.
