A near-term mission for CELSS

A study has been conducted on the mission types that may benefit from Controlled Ecological Life Support System (CELSS) technology, with emphasis on manned missions projected by NASA for the next 50 years and cost evaluations in which transportation system characteristics are factored. The CELSS analyses considered water, air revitalization, waste management, and food production. The six mission locations considered included four in the earth-moon system, together with asteroid belt and Mars surface missions. In the various locations, the radiation, solar flux and available materials scenario can be very different. It is concluded on the basis of these considerations that the short duration Mars sortie mission analyzed will not benefit from CELLS technology, while large manned bases beyond the earth-moon system will not only benefit, but positively require it.
