Since cosmic radiation significantly affects space weather and the safety of space- and ground-based technological infrastructure, its multi-scale analysis is of both fundamental and applied importance. Objective: to develop models of cosmic radiation generation across various spatial and temporal scales, from magnetohydrodynamic (MHD) processes in near-Earth space to high-energy phenomena in the interstellar medium and extragalactic objects; to assess its contribution to space weather; and to evaluate related economic and humanitarian risks, including forecasting approaches. Tasks: to determine particle injection and energization mechanisms in the Earth’s magnetosphere; to evaluate the role of turbulence and magnetic reconnection in magnetospheric energy transfer; to study solar energetic particle acceleration in flares and CME-driven shocks; to investigate interplanetary and heliospheric shocks as sources of cosmic-ray acceleration; to analyze galactic and extragalactic contributions to the observed cosmic-ray flux; to examine transient cosmic-ray enhancements from galactic and extragalactic sources; and to quantify the impact of cosmic radiation on space weather. The project combines theoretical modeling with extensive space- and ground-based observations, including in situ data. Advanced numerical simulations, large-scale data analysis, and machine learning techniques are applied to interpret, classify, and validate physical processes in space plasma.
