Project Description

Quantifying Radiation Storm Impacts on Interplanetary Missions Project (Radiation Storm Impacts)

The deleterious effects that solar energetic particles can have on spacecraft electronic systems constitute a significant concern for all space missions.  This project aims to develop tools that are capable of computing space radiation effects on spacecraft components, particularly focusing on the effects of dynamic radiation storms due to Solar Energetic Particles (SEPs) on interplanetary missions. The tools will be valuable for making operational decisions for protection of our space assets.  The capabilities developed will also have other applications in the design phase of spacecraft and for anomaly resolution.

Towards Quantifying Radiation Storm Impacts on Interplanetary Mission

The deleterious effects that solar energetic particles can have on spacecraft electronic systems constitute a significant concern for all space missions.  This project aims to develop tools that are capable of computing space radiation effects on spacecraft components, particularly focusing on the effects of dynamic radiation storms due to Solar Energetic Particles (SEPs) on interplanetary missions. The tools will be valuable for making operational decisions for protection of our space assets.  The capabilities developed will also have other applications in the design phase of spacecraft and for anomaly resolution.

The project leverages capabilities of two different directorates at Goddard to develop user-friendly tools that will provide quantitative assessment of radiation hazards, which are primary concerns of operation and wellbeing of NASA missions and humans in space.   The game-changing tools/capability resulting from the project will be of tremendous value to current and future missions, and be beneficial for spacecraft anomaly resolution. the execution of the proposed project. Real-time streams of SEP measurements from GOES, STEREOs, ACE and others have already been available on iSWA. The flexible architecture/design of iSWA allows for easy ingestion of any new data streams. Even though deterministic long-term forecasting of SEP events remains elusive, CCMC, as the world leading modeling center, ensures state-of-the –art SEP modeling capability at the time is to be utilized.
