Methods and tools for the formulation, evaluation and optimization of rover mission concepts

Traditionally, Mars rover missions have been conceived with a single point design approach, exploring a limited architectural trade space. The design of future missions must resolve a conflict between increasingly ambitious scientific objectives and strict technical and programmatic constraints. Therefore, there is a need for advanced mission study engineers to consider a wider range of surface exploration concepts in order to identify those with superior performance and robustness with respect to evolving mission objectives. To this end, a three stage trade space exploration approach has been developed to supplement point design development in the early conceptual phase of Mars rover missions. The product is an integrated set of theoretical methods and analytical tools which enhances the understanding and enables the rapid exploration of the rover mission trade space. In the formulation stage, the first stage of the approach, a parallel decomposition of the functional and physical aspects of Mars exploration architectures is employed to explore trade space of surface mission concepts. At each step of the decomposition, architectural alternatives are assessed with respect to stakeholder figures of merit.
