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.

A Solar Wind Sea Shanty

Parodying the classic sea shanty "The Wellerman," “The Solar Wind: A Heliophysics Sea Shanty” illuminates one of the primary connections between the Sun and Earth, the solar wind. This video can be shared and downloaded at YouTube .

Welcome to the Ionosphere!

This little-explored region exists between space and Earth. It is home to the aurora, the international space station, a variety of satellites, and radio communication waves. Join us as we venture to this interface to space! This video can be downloaded from the Scientific Visualization Studio

Chasing Lightning: Spritacular

Follow along and watch this wonderful introduction to our newest citizen science group, Spritacular, as they learn more about all kinds of lightning, from elves, sprits, to transient luminous events. Get involved at
