This paper presents a description of the Controlled Ecological Life Support System (CELSS) Antarctic Analog Project (CAAP) and its functionality as a pilot study for the design of a future Lunar-Mars habitat. A description of the prototype development testbed, located at Ames Research, is provided as well as an analysis of the key design parameters.The CAAP program is tasked with the development of a life support testbed at the South Pole. This facility will include food production, waste processing, and in situ energy production capabilities. The testbed will provide NASA with a remote facility located in an extremely harsh environment which has been designed to provide a useful analog to the deployment of a future Lunar-Martian habitat.NASA's program goals are the operational testing of life support technologies and the conduct of scientific studies to facilitate future technology selection and system design. The NSF goals are that the development of food production, water purification, waste treatment, and in situ energy production capabilities 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.
