... Assessment of Cost Growth. STuDy STATEMENT OF TASk After receiving the tasking letter, the National Research Council and NASA agreed to the following statement of task for this study: The National Research Council will assemble a committee to identify the primary causes of cost growth in NASA Earth and space science missions involving large, medium, and small spacecraft.

... Kennel, chair of the National Research Council's Space Studies Board, including the enclosure, "Provisional Bibliography for Science Mission Cost Growth External Independent Assessment." The NASA Authorization Act of 2008 (Section 508) directs the Administrator to arrange for "an independent external assessment to identify the primary causes of cost growth in the large-, medium-, and small-sized space and Earth science spacecraft mission classes, and make recommendations as to what changes, if any, should be made to contain costs and ensure frequent mission opportunities in NASA's science spacecraft mission programs." While a significant amount of effort has been expended in recent years, by various parties, to collect and analyze cost growth in national security and NASA science space missions, the results of these studies have not been uniformly and critically appraised, nor their implications integrated into potentially actionable modifications to mission formulation and/or development practices.

... NASA did not formally notify the NRC that it should examine additional studies. However, as noted in the main body of this report, some other documents were examined in the course of the study, some of them identified by NASA staff who participated in the open sessions of committee meetings.

... Assessment of Cost Growth (a) Study -- The Administrator shall enter into an arrangement for an independent external assessment to identify the primary causes of cost growth in the large-, medium-, and small-sized space and Earth science space craft mission classes, and make recommendations as to what changes, if any, should be made to contain costs and ensure frequent mission opportunities in NASA's science spacecraft mission programs.
