Space Station Freedom Program preliminary design review process

To conduct the Program Requirements Review of the Space Station Freedom, a Preliminary Design Review Board (PDR) has been established. The PDR will assess the preliminary design of the assembled manned base including the assembly process, the launch, and on-orbit stage configuration, the design approach, the on-orbit verification plans, supportability, reliability, safety, interfaces with the NASA infrastructure (the NSTS, TDRSS, and Ground operations) and international partners. Issues such as the coordination of a common interpretation of design requirements, coordination of interfaces, and convergence of design perspectives vs. proper allocation of resources are discussed. The impact of the resolution of the secondary ripple effect of design decisions which may cause programmatic difficulties is also addressed.
