چکیده

Evaluating risk early in concept design in order to inform the early trade studies is difficult due to the lack of information available at that early stage. This paper describes the approach used to perform a preliminary risk evaluation to inform the trade studies MIT and the Draper Laboratory are doing as part of the Concept Evaluation and Refinement (CE&R) activities of the new NASA Space Exploration Initiative.
