Abstract: On a long duration manned mission to Mars, the physiological changes caused by microgravity may be counteracted by artificial gravity. This paper evaluates several different classes of research options - a centrifuge, a free-flying animal facility, and a rotating manned spacecraft. Relative comparisons are made based on the initial constraints imposed on the facility, the operational restrictions for maintaining a healthy crew, based on research to date, and the science research requirements. The science requirements focus on the three primary physiological systems altered by microgravity - cardiovascular deconditioning, calcium loss, and muscle degradation. Significant design drivers, as well as high priority research areas and a recommended design approach are identified.
