Exploring the Heart of Space Weather with the Geospace Dynamics Constellation

Doug Rowland | The Geospace Dynamics Constellation, or GDC, will provide the first direct global measurements of Earth’s atmospheric interface to space — a region where beauty and hazards co-exist - where space weather disturbances impact communication and navigation signals, satellite orbits, and induced currents that can trigger power outages on Earth. GDC’s unprecedented multi-point observations in the heart of this interface region will provide a generational shift in perspective on this region, allowing scientists to understand this complex, interconnected system as a whole.
