                       . Parts selection, qualification, and failure mode and effects analysis (FMEA)
                         plans
                       . Contamination requirements and control plan
                       . Quality control, reliability, and redundancy
                       . Materials and processes
                       .  Acronyms and abbreviations
                       . Safety hazards identified for flight, range, ground hardware, and operations
                       . Orbital debris assessment


                       The completion of the PDR and the closure of any actions generated by the
                    review become the basis for the start of the detailed drafting and design effort and
                    the purchase of parts, materials, and equipment needed.
                       The CDR is held near the completion of an engineering model, if applicable, or
                    the end of the breadboard development stage. This should be prior to any design
                    freezing and before any significant fabrication activity begins. The CDR presents a
                    final detailed design using substantially completed drawings, analyses, and bread-
                    board or engineering model evaluation testing to show that the design will meet the
                    final performance and interface specifications and the required design objectives.
                    MEMS selection, de-rating criteria, screening results, calculated reliability, and the
                    results of a FMEA are to be presented. The CDR should include all of the items
                    specified for a PDR, updated to the final present stage of development process, in
                    addition to the following items:
                       . Evolution and heritage of the final design
                       . Combined optical, thermal, and mechanical budgets or total system
                         performance
                       . Closure of actions from the previous review
                       . Interface control documents
                       . Final implementation plans including: engineering models, prototypes, flight
                         units, and spares
                       . Engineering model or breadboard test results and design margins
                       . Completed design analyses
                       . Qualification and environmental test plans and test flow
                       . Launch vehicle interfaces
                       . Ground operations
                       . Progress and status and control methods for all safety hazards identified at,
                         but not limited to, the PDR
                       .  Reliability analyses results: FMEA, worst-case analysis, fracture control
                       . Plans for shipping containers, environmental control, and mode of
                         transportation
                       . Problem areas and open items
                       . Schedules
