Execute a balanced science program based on discipline-specific guidance from the national academies of sciences engineering and medicine administration priorities and direction from congress

NASA's Shared Services Center awarded Trustees of Boston University $315,217 on October 1, 2025, under the Science program (CFDA 43.001) for research on cutoff rigidity and solar proton trapping using magnetohydrodynamic and convection modeling. The Science Mission Directorate program supports hypothesis-driven research across astrophysics, biological and physical sciences, Earth science, heliophysics, planetary science, and lunar exploration conducted by the nation's STEM research community using NASA's space observatories and spacecraft missions.

The research involves test-particle simulations using the global Lyon-Fedder-Mobarry magnetohydrodynamic model and the GAMERA model coupled with the Rice Convection Model, with case-by-case analysis of cutoff rigidity and solar proton trapping. Boston University is the prime recipient and will coordinate project activities, develop scientific publications, and host project communications.

The period of performance runs through August 5, 2026. Work is performed in Boston, Massachusetts.

Trustees of Dartmouth College serves as a sub-recipient, with Dr. Maulik Patel supporting the principal investigator in conducting test-particle simulations, participating in project teleconferences, and drafting sections of papers and scientific presentations. Dartmouth College's sub-award was issued on March 26, 2026.
