A Guide to on-line data from The Dynamics Explorer Program

Dynamics Explorer (DE) -1 and -2 Satellites


The two Dynamics Explorer spacecraft were launched on 3 August 1981 into coplanar polar orbits at different altitudes for the purpose of studying interactive processes within the atmosphere-ionosphere-magnetosphere system. DE 2, with an altitude range of 300 km to 1000 km, re-entered the atmosphere on 19 February 1983. DE 1 had an altitude range of 570 km to 23 000 km (3.63 Earth radii) and its operations ceased in January 1991.

The general objective of the Dynamics Explorer program is to investigate magnetosphere-ionosphere-atmosphere coupling processes. Specific objectives fall into five categories:

A list of publications describing the DE program is currently being compiled.

More information about the DE Program is available from NASA.

Sources of On Line Data

On line data and information from specific instruments

Instrument descriptions and instructions on how to obtain data from the NDADS system at the National Space Science Data Center.
  • The SDDAS system at the Southwest Research Institute

    On line data for selected intervals from DE -1 and DE -2 is also available from the Southwest Data Display and Analysis Syst

    On line data from other satellite programs are available on the Magnetospheric On-Line Data pages of the Space Physics Data System.
