From MIR to ISS Experiment on study of plants’ growth and ripening in space flight conditions

Explore the study of plants' growth and ripening in space flight conditions through the creation of a technical complex "Greenhouse" on the ISS. This experiment aims to develop a system for plant cultivation under space flight conditions, optimize plant growth, and establish an environmental control system. The research also focuses on the potential of plants to assist in atmospheric balance by producing oxygen and absorbing carbon dioxide. The experiment involves the use of advanced equipment such as the "Light" Greenhouse, gas analyzers, humidity sensors, and environmental parameter measurement systems. The goal is to lay the groundwork for future biotechnical life support systems in space. Additionally, the experiment "PLANT-2" aims to conduct fundamental biology research and optimize plant cultivation procedures for prospective space life support systems. Key objectives include studying the cultivation technology of vegetables, analyzing plant reproductive functions, and assessing the impact of microgravity on plant development. The research equipment includes the modular Greenhouse "LADA" and specialized tools for data collection. Through these experiments, valuable insights into plant growth in space could revolutionize technologies for sustainable life support systems on spacecraft.

  1. From MIR to ISSExperiment on study of plants’ growth and ripening in space flight conditions

  2. “GREENHOUSE” SPACE EXPERIMENTGOALS creation of technical complex to grow plants on-board space stationstudy of plants’ growth and ripening in space flight conditionsSPACE EXPERIMENT FACILITIESTECHNICAL STUFF – The “Light” Greenhouse equipped with gaging equipment (joint working out of the Institute of Biomedical Problems and Space Research Institute of Belarusan Academy of Science)FLIGHT EQUIPMENT: plants growing chamber; plant-house (root module); lighthead; control unit.GAGING EQUIPMENT: gas analyzer (GAS) – designed by US personnel; pouch with substratum humidity sensors; system of environmental parameters measurements (EDS); power unit (PDS); PC (data collection and operation).

  3. EXPERIMENT CHRONICLE

  4. EXPERIMENT CHRONICLE Experiment results Creation of System of plant cultivation in space flight conditions Polished up conditions of plant growth and surrounding parameters control system There is a first wheat cultivation in space flight, plants has passed the total circle of its biological conditions Principal investigator: Institute of Biomedical Problems(Russia)

  5. Greenhouse “Light” Sprouts of “Apogee” wheat

  6. Results and analysis

  7. Results and analysis Problems: Station close volume factor could make negative influence on plants development. Goal for the future – to organize sufficient environmental control.

  8. Special direction of biological researches is a studying of possibility of the total cycle of plants development under space flight conditions. There is greenhouse which is called LADA on-board ISS. Its’ goal to grow up small number of plants, which could be added to crew’s food. These are salads in general (Pekinese cabbage, etc). Optimal conditions of their growing are working out. Estimated that big greenhouse will be delivered to ISS. This greenhouse will permanently work and crews will have fresh salads on lunch.Final goal of these studies on plants and domestic animals growing should be creation of bio-technical life support system. Plants, besides their food value, will produce oxygen, will absorb carbonic acid thereby will partially renew atmospheric balance of space station.

  9. SCIENTIFIC RESEARCHES ON THE ISS RUSSIAN SEGMENT BIO_MEDICAL RESEARCHES AND EXPERIIMENTSEXPERIMENT “PLANT-2” Scientific Advisor: Sytchev V.N. Goal: • Realization of researches to solve questions of fundamental biology and optimization of plants cultivation procedures for future greenhouses as a part of prospective space life support systems. Objectives: • Assembling and preparation of equipment to perform experiment. • Study of features of greenhouse LADA plant unit water-air condition under space flight conditions. • Study of cultivation technology of vegetables (Midzuna salad, Micro-Tom tiny tomatoes, tiny (red) pea) as applied to regular greenhouse units. • Study of space flight factors on growth and development of plants, which are prospective for usage in space vitaminous conservatories. • Study of plants germinating and vital ability. • Study of plants development phenology. • Study of plants reproductive function and getting of the second generation of space seed. • Study of chemistry of plants and seed, grown in microgravity, to determine the percentage of nitrogenous compounds in vegetative biomass. • Determination of ethylene concentration in ISS Russian segment atmosphere. Expected results: Evaluation of productive characteristics of legumes and leaf vegetables in microgravity, perfect of agrotechnical methods to advance technologies of close ecological life support system onboard of space vehicles.
