The Health Maintenance Facility (HMF) is the code name for a space-based medical clinic. The HMF is an integral part of the U.S. sponsored space station program due to be launched in the late 1990s. Contained in this module will be equipment, facilities, and supplies that can be used to support space station crew health. The range of medical care will depend upon the skill of the crew, the tools available, and the support systems that can be used from earth. The design of this system and its heavy dependence upon computer resources provide an excellent model for looking forward into the earth based medical clinics of the future.
