Geospace Dynamics Constellation (GDC): Exploring Magnetosphere-Ionosphere Coupling

NASA's Geospace Dynamics Constellation (GDC) is the next Living With a Star (LWS) strategic mission, designed to revolutionize our understanding of Earth's upper atmosphere and its response to solar and solar wind energy inputs. Consisting of six identical spacecraft in polar low earth orbits, GDC will make the first systematic multipoint studies that can characterize how energy flows through and transforms this part of near-Earth space. With a launch expected early next decade, GDC will provide critical new scientific and space weather observations and serve as a strategic hub for other efforts to understand Geospace.
