From page 638... ... 638 ORIGINS, WORLDS, AND LIFE FIGURE C-1 Schematic illustration of the flow of the Aerospace Corporation's technical risk and cost evaluation (TRACE) process. Read the entire page →
From page 639... ... APPENDIX C 639 The evaluation of technology, cost, and schedule are inextricably intertwined. However, it is easier to describe each element of the overall analysis (e.g., technical, schedule, and cost) Read the entire page →
From page 640... ... 640 ORIGINS, WORLDS, AND LIFE on the information provided by the various mission study teams with a focus on treating all projects equally. To be consistent for all concepts, the TRACE cost process allows an increase in cost resulting from increased contingency mass and power, increased schedule, increased required launch vehicle capability, and other cost threats depending on the concept maturity and specific risk assessment of a particular concept.

From page 641... ... APPENDIX C 641 TRACE RESULTS FOR PRIORITY MISSIONS Summaries of the results of the TRACE evaluations of the 17 priority missions identified by the decadal survey because of their potential to address the 12 key science goals (see Chapters 4 to 15) and potential technical viability presented in Boxes C-1 through C-18.
