“…Due to its favorable properties (e.g., high nutrient content, granular solidity, long-term usability, weed resistivity, etc. ), Balkanine was selected as growth substrate for the Bulgarian-built Svet growth chamber onboard the Mir Space Station in 1990 (Bingham et al, 2000). A preliminary experiment carried out onboard Salyut-7 OS in 1985 identified beneficial hydrodynamic properties for different fractions of Balkanine (Ivanova, 1997).…”

Growing plants to facilitate life in outer space, for example on the International Space Station (ISS) or at planned deep-space human outposts on the Moon or Mars, has received much attention with regard to NASA's advanced life support system research. With the objective of in situ resource utilization to conserve energy and to limit transport costs, native materials mined on Moon or Mars are of primary interest for plant growth media in a future outpost, while terrestrial porous substrates with optimal growth media characteristics will be useful for onboard plant growth during space missions. Due to limited experimental opportunities and prohibitive costs, liquid and gas behavior in porous substrates under reduced gravity conditions has been less studied and hence remains poorly understood. Based on ground-based measurements, this study

“…The objectives were to study the impact of changes in substrate moisture levels and waterlogging on height, phenological characteristics and physiological response (plant growth parameters, photosynthesis, etc.). Waterlogging of the substrate medium was set to imitate the excessive water levels and the unfavorable aeration status of the substrate medium that occurs in the root zone in microgravity [16,17,18]. Another three experiments (E-4,5,6) were conducted with salad plants: lettuce (Lactuca sativa L. Lolo Rosa) and Chinese cabbage (Brassica rapa var pekinensis cv.…”

The next steps to the development of an advanced SVET-3 Space Greenhouse with wider parameter monitoring and adaptive control of the shoot and root environment so as to provide most favorable conditions for plant growth and development are presented. A new system for precise plant shoot zone environment monitoring was added to the existing SVET-2 SG equipment (using the ME-4610 data acquisition system). Some main sensors sub-systems for measurement of light intensity, air humidity, temperature, air pressure and air flow velocity were developed and described. Laboratory verification tests of these systems in two experiments with different lettuce plants variety and chamber volume were carried out. Ground research was performed to study the processes going in the root zone medium in earth and model microgravity conditions and on this basis to make some optimizations for providing adequate root environment in space. Biotechnical experiments were carried out to investigate the plant response to artificial hypo-oxygen and waterlogging "stresses" in substrate Balkanine. The results obtained showed that even a small rise of moisture in the substrate when saturation has occurred in the bottom layers can lead to oxygen deficiency in the plant root area and to photosynthesis reduction as a result.

“…These international experiments laid the groundwork for many of the new plant growth activities that are being planned for the ISS, and provided several keynote discoveries and demonstrations in the last decade. These include: the development of a reliable substrate moisture control system (Ivanova and Dandolov, 1992;Bingham et al, 1996;Bingham et al, 1999;Jones and Or, 1999), the identification ethylene as the limiting factor in earlier seed to seed failures (Salisbury, 1997;Campbell et al, 2001) and the identification of the likely ethylene source (Bingham et al, 2000). This experiment sequence also included the first replicated seed to seed experiment (Brassica rapa L. Musgrave et al, 2000), and the first two-generation microgravity seed production experiment (Sytchev et al, 1999;Bingham et al, 2000).…”

Lada, named for the ancient Russian Goddess of Spring, is a plant growth system developed jointly by the Space Dynamics Laboratory and the Institute of Biomedical Problems for longterm deployment on the International Space Station. Lada uses design features and technology similar to the Svet greenhouse on the Mir orbital outpost, and will be launched to ISS in June 02. It is scheduled to support its first crop (a leafy vegetable-Mizuna [Brassica rapa var. nipposinica]) in October 02. Lada consists of four major components (a control module, two vegetation modules and a water tank) and is designed to be deployed on a cabin wall. This deployment scheme was chosen to provide the crew therapeutic viewing and easy access to the plants. The two independently controlled vegetation modules allow comparisons between two vegetation or substrate treatments. The vegetation modules consist of three sub-modules, a light bank, the leaf chamber, and a root module. The root module is 9 cm deep, and can be instrumented to allow a wide range of substrate water and oxygen diffusion experiments to be conducted during the plant growth experiments. Sensors available in Lada are similar to those provided by the Svet-GEMS system. Specific attention has been paid to the root zone sensor suite, which includes substrate moisture probes, minitensiometers, and substrate oxygen sensors. Experiments conducted in Lada will be associated with the Russian National Science program and will follow three themes: substrate management physics, plant production and quality, and crew-plant interaction studies. A unique feature of the Lada concept is that when the system is not being used for supported science experiments, it will be available to crew members to supplement their diet and to enhance flight enjoyment. Plans are in place to train all of the Russian crew members to use Lada. International cooperative experiments exploiting these unique features are now being developed.
