Preliminary indication on the technological systems for an Italian Space Greenhouse

For extended human presence in space, shipping all food, oxygen and water from the Earth will be costly. Besides, some food items desired in the diet will not keep long enough and so the only alternative is to growing them aboard. Plants can produce food and oxygen for human needs, can contribute to remove and reclaim carbon dioxide, excess of humidity and the organic wastes. The international scientific community has been making efforts towards developing technologies to realise a sustainable Bioregenerative Life Support System. In this paper some indications on the technological systems for an Italian Space Greenhouse are described.
