Operations considerations in Space Station Freedom assembly

The importance of planning the on-orbit operations inherent in the Space Station Freedom assembly sequence is discussed. Any solution to the assembly puzzle requires the simultaneous satisfaction of many diverse constraints, including: on-orbit assembly operations, NSTS (National Space Transportation System) payload bay constraints, NSTS performance capabilities, and provision of the requisite functionality for each on-orbit configuration. Because operations are in the critical path SSFP (Space Station Freedom Program) has chosen to carefully assess assembly operations as each launch manifest is developed and evaluated.
