Polar, Wind, and Geotail are fundamental elements in NASA's global approach to understanding
the Sun-Earth Connections system.
Operating as a distributed laboratory in space, events are routinely followed from their birth on the Sun,
traced through the interplanetary medium, and then studied in terms of their effectiveness in creating geomagnetic storms
and substorms in our near Earth environment.
The focus is on understanding the dynamics -- short- and long-term, large and small,
through active and quiet solar periods. |
