The International Space Exploration and Colonization Company (ISECCo) has been committed to the advancement of space colonization since 1988. Critical to the human habitation of space is life support technology which includes sustainable food production. ISECCo has built a semi-Closed Ecological Life Support System (Semi-CELSS) facility in preparation for designing a fully closed system. We are currently operating the semi-CELSS, named Mars Base Zero, to achieve a balanced diet that minimizes crop area and maximizes yield. Mars Base Zero uses strictly soil based techniques such as one would use on Mars. The 2002 operation of Mars Base Zero and crop yield are discussed at length.
