Controlled Ecological Life Support Systems (CELSS)
At Purdue University 1990-1995

Purdue University was host to the NASA Specialized Center for Research and Training (NSCORT) in Bioregenerative Life Support from 1990 to 1995. This multi-disciplinary research center was dedicated to the design and development of Bioregenerative and Controlled Ecological Life-Support Systems for long-duration manned space and terrestrial applications. The mission and operations of the former center are described in accompanying documents. The Center was disbanded in November of 1995. More information about the NSCORT Program at that time also is available. A few resources are maintained on this website, as well as a historical record of the center. More information about the website's history is available.
