The Space Station Freedom (SSF) is being designed to serve as a permanently manned platform in space to accommodate a growing amount of supported scientific research and, ultimately, to provide the capability to process lunar/Mars mission vehicles for the Space Exploration Initiative (SEI). In order to support the evolving requirements of these future missions, the resources available on board the Space Station must grow beyond that of the Permanently Manned Capability (PMC) baseline configuration. One of the most critical resources for this accommodation of future needs will be the addition of pressurized volume. The changes made to the baseline program during the Restructuring activity of 1990 - 91, particularly the resizing of the U.S. Habitation and Laboratory Modules from 44 feet to 28 feet in length and the utilization of pre-integrated truss (PIT) sections, necessitates a careful re-analyzing of the evolution configuration module pattern. The module pattern has an effect on general station growth including such issues as manifesting and assembly, logistics, crew safety, operations, and utilization.
