TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
High-energy space radiation from Galactic Cosmic Rays and Solar Particle Events (SPEs) pose significant risks to equipment and astronaut health in NASA missions. Energetic particles from SPEs associated with flares and coronal mass ejections (CMEs) may adversely affect not only beyond-Low-Earth-Orbit missions, but also aircraft avionics, communications, and airline crew/passenger health. It is crucial to develop a capability to forecast SPEs and their effects on systems to guide planning of mission-related tasks and risk mitigation strategies.
CFD Research Corporation (CFDRC), University of Alabama in Huntsville (UAH), and Vanderbilt University (VU) propose to develop a comprehensive forecasting capability - SPE Forecast (SPE4) - comprising state-of-the-art modules integrated within a novel computational framework. SPE4 will include: (a) the MAG4 code for probability forecasts of flares/CMEs, and SPEs, (b) the PATH code for solar particle transport through the heliosphere, (c) Geant4-based transport calculations including geomagnetic modulation and atmospheric interactions (for avionics) to yield spectra of SPE-induced energetic protons/heavy ions, interfaced to (d) the CR?ME96 code for calculation of resulting effects in electronics.
In Phase I, we demonstrated the superior capability of MAG4, PATH, and Geant4 for their respective tasks using a prior solar event case. A controller script was developed for automated code execution and data transfer across interfaces. Functionality of the overall event-to-effects capability was demonstrated using the 28-Sep-2012 event. We developed a concept of the final software product for NASA based on client-server architecture. In Phase II, we will collaborate with VU to interface calculated particle spectra with CR?ME96 to determine single-event effects in electronics. We will enhance robustness, accuracy, and execution speed via improved models and procedures, and demonstrate the software for persistent 24x7 SPE monitoring.
POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The proposed effort is aligned with the goals of NASA?s Living With a Star (LWS) program that is focused on developing a predictive understanding of solar activity and its effects on Earth and space-based assets. The newly developed and validated ?event-to-effects? modeling capability will be synergistic to the strategic capability models available to the scientific community (e.g., via the Community Coordinated Modeling Center ? CCMC - at Goddard/GSFC). In fact, the MAG4 solar activity forecasting code within the overall SPE4 package is already (individually) available from CCMC. With the emphasis on linking the calculated particle spectra with CR?ME96 to calculate effects in electronics, optimizing SPE4 interfaces and calculation procedures, and continued validation, this project will also focus on transition towards operational use.
This effort also addresses objectives outlined in NASA?s Human Research Roadmap and OCT Technology Roadmap TA06 ? Human Health, Life Support, and Habitation Systems, in particular, the sub-technology area of Radiation, including Space Weather Prediction and Protection Systems. The SPE4 software will specifically address the limitations facing mission operational planning in terms of forecasting the occurrence, magnitude, and all-clear periods of SPEs. The SPE4 framework will also support interfaces to other downstream codes for radiation effects calculations (e.g., to analyze and design effective shielding materials).
POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Dynamic variations in the high-energy, highly-penetrating solar particle environment can adversely affect aircraft (especially near the Poles), cause navigational and GPS equipment interference, disrupt spacecraft electronic systems, and cause disruption/equipment failure in communication systems. For DoD agencies and commercial entities with space-based or high-altitude assets, an efficient and accurate predictive capability for the radiation environment at desired locations or along preset trajectories, and resulting effects caused in systems (electronics, materials), will be a significant aid to mission planners for scheduling tasks and to adopt risk mitigation strategies for equipment.
Changes in the Earth?s ionosphere due to SPEs can modify the transmission path and even block transmission of High Frequency (1-30 MHz) radio signals. These frequencies are used by amateur (ham) radio operators, commercial airlines, and government agencies such as the Federal Emergency Management Agency and the Department of Defense. Terrestrial applications such as electric power transmission systems can be affected by SPE-induced changes to the geomagnetic field leading to blackouts. Induced stray currents leading to corrosion in above-ground oil pipelines (near the Poles) is another concern. In all these cases, a predictive capability for SPE-induced radiation level spikes can help equipment managers intelligently manage operations and prevent catastrophic failures.
