The concept definition, trade-offs, and ultimate selection of a nuclear thermal propulsion (NTP) system that will enable the Space Exploration Initiative (SEI) missions to Mars will require a rigorous systems engineering approach. A systems engineering process to provide a consistent comparison has been established to allow for evolving SEI mission requirements, level of concept definition and changing customer'' requirements, while continuing to improve the process as more data becomes available. All concepts will be evaluated against an established baseline NTP system to compare system benefits and merits. Establishing the evaluation criteria is extremely challenging and critical to the evaluation and selection process. Quality function deployment (QFD) will be utilized to provide structure and focus in obtaining the critical needs and attributes of the NTP system. System performance, cost, and risk analysis tools will be integrated into the process to provide the quantitative data required to allow for an informative decision on concept and technology decisions. This process will initiate the framework for design and development of a robust, reliable, cost effective NTP engine within NASA's philosophy for space systems to be developed faster, better, and cheaper.''
