The CELSS Antarctic Analog Project (CAAP) is a joint NSF and NASA project tor the development, deployment and operation of CELSS technologies at the Amundsen-Scott South Pole Station. CAAP is implemented through the joint NSF/NASA Antarctic Space Analog Program (ASAP), initiated to support the pursuit of future NASA missions and to promote the transfer of space technologies to the NSF. As a joint endeavor, the CAAP represents an example of a working dual agency cooperative project. NASA goals are operational testing of CELSS technologies and the conduct of scientific study to facilitate technology selection, system design and methods development required for the operation of a CELSS. Although not fully closed, food production, water purification, and waste recycle and reduction provided by CAAP will improve the quality of life for the South Pole inhabitants, reduce logistics dependence, and minimize environmental impacts associated with human presence on the polar plateau.

The CELSS Antarctic Analog Project (CAAP) is providing NASA and the National Science Foundation (NSF) with an understanding of the complex and interrelated elements of life support and habitation, both on the Antarctic continent and in future missions to space. CAAP is providing a method for challenging the assumption upon which the application of regenerative life support systems are based and thus is providing a heritage of reliability and dependable function. Currently in the early stages of the project, CAAP is laying a path in addressing system engineering issues, technology selection and integrated operation under a set of relevant and real mission constraints. Recent products include identification of energy as a critical limiting resource in the potential application of regenerative systems. Alternatives to the traditional method of life support system development and energy management have been developed and are being implemented in the CAAP testbed.
