Abstract

Long duration and complex mission scenarios are characteristics of NASA's human exploration of Mars, and will provide unprecedented challenges. Systems reliability and safety will become increasingly demanding and management of uncertainty will be increasingly important. NASA's current pioneering strategy recognises and relies upon assurance of crew and asset safety. In this regard, flexibility to develop and innovate in the emergence of new design environments and methodologies, encompassing modelling of complex systems, is essential to meet the challenges.

Keywords: space missions; reliability; safety; assurance cases; uncertainty; complexity; objectives; model-based systems engineering; model-based mission assurance; Bayesian methods.
