Mission robustness starts with science requirements definition
|Author||Smith, Clayton; Kinnison, James;|
|Abstract||In the early development stages for Parker Solar Probe (PSP), the Johns Hopkins University Applied Physics Laboratory (JHU/APL) team mapped the mission’s top-level requirements to mission success criteria to ensure that a failure of any one science instrument would not translate to a failure of the entire mission. This paper details this analytical process and shows how the results were folded into the reliability assessments. The Interstellar Probe study team is also using this process to define mission success criteria. Interstellar Probe faces the added challenge of being a 50+ year mission with science objectives at each epoch during its flight. Designing the science objective – instrument interface will increase the mission reliability without paying the mass penalty of simply using a redundant payload.|
