2000 for testing crops for space, and have since expanded their testing for a wide range of controlled environment agriculture topics. The Canadian team eventually developed sophisticated canopy-scale hypobaric plant production chambers ca. A Canadian research team at the University of Guelph developed a research facility ca. The European Space Agency MELiSSA Project began in the late 1980s and pursued ecological approaches for providing gas, water and materials recycling for space life support, and later expanded to include plant testing. CEEF had 150 m2 of plant growth area, which provided a near-complete diet along with air and water regeneration for two humans and two goats. About this same time, Japanese researchers developed a Controlled Ecological Experiment Facility (CEEF) in Aomori Prefecture to conduct closed system studies with plants, humans, animals, and waste recycling systems. Related tests with humans and crops were conducted at NASA’s Johnson Space Center in the 1990s. Findings from these studies were then used to conduct tests in a 20 m2, atmospherically closed chamber located at Kennedy Space Center. 1980 with testing focused on controlled environment production of wheat, soybean, potato, lettuce, and sweetpotato. NASA initiated its Controlled Ecological Life Support Systems (CELSS) Program ca. Studies on algal production and controlled environment agriculture were also carried out by Russian researchers in Krasnoyarsk, Siberia beginning in 1960s including tests with human crews whose air, water, and much of their food were provided by wheat and other crops. Research in the area started in 1950s and 60s through the works of Jack Myers and others, who studied algae for O2 production and CO2 removal for the US Air Force and the National Aeronautics and Space Administration (NASA). Central to the concept is the use of photosynthetic organisms and light to generate oxygen and food. Such research and technology development will be crucial to long-term habitation of space by humans.Agricultural systems for space have been discussed since the works of Tsiolkovsky in the early 20th century. The Lab is exploring various aspects of a bioregenerative life support system.
Wheeler and other colleagues are researching plant growth under different types of light, different CO2 concentrations and temperatures. The other plants are Bibb lettuce (left) and radishes (right). In a plant growth chamber in the KSC Space Life Sciences Lab, plant physiologist Ray Wheeler checks onions being grown using hydroponic techniques.

If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file.
