Status: Completed
Mission Category: Historical Missions
Launch Date: August 3, 1981
Launch Location: Vandenberg Air Force Base, CA

The Dynamics Explorer (DE) mission’s general objective was to investigate the strong interactive processes coupling the hot, tenuous, convecting plasmas of the magnetosphere and the cooler, denser plasmas and gases corotating in the Earth’s ionosphere, upper atmosphere, and plasmasphere. Two satellites, DE 1 and DE 2, were launched together and were placed in polar coplanar orbits, permitting simultaneous measurements at high and low altitudes in the same field-line region.
