Can CO2 be Used as a Pressurizing Gas for Mars Greenhouses?The possibility of using plants to provide oxygen (O2) and food during space travel has been discussed and studied for nearly 50 years. The concept is based on the process of photosynthesis, which uses CO2 as a substrate and is driven by light (photosynthetically active radiation - PAR0 in the 400 to 700 nm waveband. In addition to the CO2 and light, the plants would require a controlled environment with acceptable temperatures (approx. 10 to 35 C) and humidities (approx. 40 to 85 %), adequate supplies of water and mineral nutrients, and minimum levels of oxygen to sustain respiration.
