The Heliophysics Research Program supports investigations in all research regimes of Heliophysics. The program supports investigations of the Sun, including processes taking place throughout the solar interior and its atmosphere, as well as the evolution and cyclic activity of the Sun. It supports investigations of the origin and behavior of the solar wind, transient structures, energetic particles, and magnetic fields in the heliosphere and their interaction with the Earth and other planets, as well as with the interstellar medium. The program supports investigations of the physics of magnetospheres, including magnetic reconnection, fundamental interactions of plasma wave-particle interactions and particles with guide fields, as well as coupling to the solar wind and ionospheres. It supports investigations of the physics of the terrestrial mesosphere, thermosphere, and ionosphere, neutral and ionized, and coupling of these phenomena to the lower atmosphere and magnetosphere. It supports investigations focused on processes that create space weather events, and investigations to enable a
capability for predicting future space weather events.
The Heliophysics Research Program also supports investigations that span the regimes and address a systems approach – emphasizing the understanding of fundamental processes and interconnections across the traditional science disciplines, on a broad range of spatial and temporal scales. In concert with the other NASA science divisions (Planetary Science, Astrophysics, Earth Science, and Biological and Physical Sciences), the program shares responsibility for learning about the Earth, our Solar System, the Universe, and their interrelationships.
