First global measurements of Earth's upper atmosphere-magnetosphere coupling
The Geospace Dynamics Constellation (GDC), a multi-spacecraft constellation, will provide a platform for the coordinated and simultaneous measurements of both neutral gas and plasma needed to advance scientific understanding of the Earth’s coupled ionosphere-thermosphere system on a global scale. The mission, which is part of NASA’s Living With a Star program, will be a key step towards understanding the basic chemistry and physics of Earth’s upper atmosphere and its interaction with the magnetosphere. The mission will also give scientists new insights into space weather processes.
