| dc.description.abstract | In long-term plans for space exploration investigated by major space agencies, the exploration of the Moon or Mars involves solving many technological problems. One of them is the development of an efficient and robust life-support system. One-way trip to Mars will take between 6 to 8 months with current technology. According to NASA�s economic calculations, for each trip over 10 months, at least 15% of the food for astronauts should be produced onboard. To make this possible it is necessary to switch from physicochemical (PC) systems in charge of recycling water and oxygen and stabilization of waste - like the one on the International Space Station - to hybrid ones where part of the system can be based on PC technology and part of it on biological processes in order to produce edible biomass, e.g. to grow plants. As the growth and development of higher plants are strongly influenced by the environmental conditions, bio-regenerative life-support systems require a high level of control and management. In systems that include plants, it is possible to use transpiring water as a source of potable water, which in turn can reduce the need for physical purification systems. For this to be possible, it is necessary to understand in-depth how the various parameters affect the plant growth and transpiration process - especially in closed systems. Most of the existing plant growth models do not consider gravity, radiation, or CO2 concentration as variable parameters. However, over the years, new models are being developed in controlled environments. This article presents an overview of the existing models with a focus on the ones that can be used to simulate systems in space. The article also highlights the work that still needs to be done to understand the impact of certain parameters on plant growth for a closed-systems application. | |
