Heliophysics Science Division

NASA's Heliophysics Science Division, of the Goddard Space Flight Center, conducts research on the, its extended solar system environment (the ), and interactions of , other planets, small bodies, and interstellar gas with the heliosphere. Division research also encompasses geospace—Earth's uppermost atmosphere, the ionosphere, and the magnetosphere—and the changing environmental conditions throughout the coupled heliosphere (solar system weather).

Heliosphere research
NASA's studies of the heliosphere include research into: how the solar wind behaves near Earth; what causes and sustains magnetic and electric fields around other planets; how the heliosphere interacts with interstellar medium; what the boundaries of the heliosphere look like; the origins and development of and interstellar cosmic rays; and what may contribute to the habitability of.

The field is intensely cross-disciplinary with planetary scientists, astrophysicists, astrobiologists, and space weather researchers. NASA heliophysics missions that contribute to heliospheric research are: the Advanced Composition Explorer; NOAA's Deep Space Climate Observatory, the Interstellar Boundary Explorer, the Solar Terrestrial Relations Observatory; Voyager, and Wind. The on such NASA missions as Maven and Juno, observe the space around  and Jupiter respectively, contributing to heliospheric research.
