| Use of Preliminary PRA to Inform Decisions During Initial NASA Gateway Development |
|---|
| How do you use Probabilistic Risk Assessment (PRA) to support a program in development before designs are even known? Traditional PRAs require detailed design information and early in a program life cycle such information is not available. National Aeronautics and Space Administration (NASA) Safety and Mission Assurance (SMA) developed a preliminary PRA for the Gateway Program based upon NASA reference designs utilizing data and models from pervious PRA studies as surrogates for the Gateway systems. Gateway will be a lunar outpost that supports missions to the moon and includes several elements/modules developed by NASA and International Partners. NASA SMA began supporting Gateway in fall 2017 during initial formulation and continues to support the Gateway Program today. This paper will explore how the NASA SMA developed preliminary PRA was used to inform Gateway Program decisions with specific examples provided. |

Lead Author Name: Teri Hamlin (Teri.l.hamlin@nasa.gov)
Bio: Teri Hamlin is the Gateway Probabilistic Risk Assessment (PRA) Lead at Johnson Space Center (JSC). As the Gateway PRA Lead, she is responsible for development of PRA models to assess Loss of Crew (LOC) and Loss of Mission (LOM) risk for Gateway, performing risk trades as needed. Prior to joining the Gateway team Hamlin was the Commercial Crew Program (CCP) PRA lead where she initially assisted in the development of commercial crew requirements and PSA methodology and eventually provided insight into the commercial providers LOC and LOM assessments. Hamlin began her career at JSC Safety and Mission Assessment (SMA) Analysis Branch in the Shuttle Program as the Shuttle PRA Lead until Shuttle retirement following STS-135 in July 2011.
