This is the home page for NASA's Heliphysics Science Division (HSD). The Division is located at the Goddard Space Flight Center (GSFC) in Greenbelt, MD, USA. It is a component of Goddard's Sciences and Exploration Directorate.
The Heliophysics Science Division (HSD) provides scientific leadership and expertise necessary to achieve NASA’s strategic science goals in solar physics, heliospheric physics, geospace physics and space weather. It leads the definition and development of missions in support of these goals and performs fundamental research into solar structure and magnetic activity, the origins and acceleration of the solar wind, the effects of solar outbursts on the heliosphere, the response of the coupled magnetosphere-ionosphere system at the Earth and other planets to solar variability including solar irradiance. HSD’s scientists develop coupled models of the sun and its corona, the heliosphere, geospace, and the high altitude environments of all of the planets, and they propose, develop and fly state-of-the-art instrumentation for photon and neutral atom imaging, electric and magnetic field mapping, and plasma and energetic charged particle measurements. HSD also designs and implements unique data systems that manage a wide range of solar-terrestrial data and enable rapid access and analysis across mission and discipline boundaries for the United States space science community. The scientists in the HSD interpret and evaluate data gathered from its instruments, draw comparisons with computer simulations and theoretical models, and publish the results. HSD’s education and outreach activities communicate the excitement and societal relevance of NASA’s operating and future Heliophysics missions.
