The objective of this study is to provide a clear picture of SPS space transportation costs at the present time with respect to their accuracy as stated, the reasonableness of the methods used, the assumptions made, and the uncertainty associated with the estimates. The approach used consists of examining space transportation costs from several perspectives - to perform a variety of sensitivity analyses or reviews and examine the findings in terms of internal consistency and external comparison with analogous systems. These approaches are summarized as a theoretical and historical review including a review of stated and unstated assumptions used to derive the costs, and a performance or technical review. These reviews cover the overall transportation program as well as the individual vehicles proposed. The review of overall cost assumptions is the principal means used for estimating the cost uncertainty derived. The cost estimates used as the best current estimate are included.
