I have found no indication from my limited sources that free nitrogen or nitrates have been found on Mars.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3018109763320526772.post-37719115392880496672009-02-28T10:14:00.000-08:002009-02-28T10:14:00.000-08:00A martian greenhouse should have an insulated floo...A martian greenhouse should have an insulated floor, in other words, an inflatable bubble. It should have lightweight, flexible, supports so it doesn't depend entirely on pressure to hold its shape. It must have heating and supplemental lighting. A mixture of flourescent and full spectrum lamps might provide enough light to simulate Earth-like illumination. The bubble could be inflated initially with native CO2. A Sabatier reaction machine could separate oxygen from the CO2 in the Martian regolith, for use in the human habitat and in the greenhouse. Gradually O2 levels would increase. Don't count on vegetables to produce oxygen. As food is harvested periodically, Oxygen levels will drop. Grow trees as well, for latex (euphorbia), and cellulose for plastics. Fruit trees are useful, as only the fruit is harvested, while the leaves continue to produce oxygen, and the trunks sequester carbon. DO NOT plant in the regolith. Forward contamination is the first step in Terraforming - if that is not the mission objective, don't do it. Also, if there are micro-organisms in the regolith their effects on Terrestrial life is unknown. Furthermore, frigid ground temperatures would make heating the greenhouse difficult.<BR/>Powering the heaters and lights cannot be done by solar without a very large array. Other power sources will have to be found.<BR/>Finally, due to the weight of the necessary equipment, launch it seperately from the crew habitat. The crew habitat might integrate some kind of hydroponic garden into its structure. Zero G gardening is an unknown, so maybe activate the habitat garden after arrival on MarsAnonymousnoreply@blogger.com
