The science objectives of the WIND mission are:
* Provide conplete plasma, energetic particle, and magnetic field input for magnetospheric and ionospheric studies.
* Determine the magnetospheric output to interplanetary space in the up-stream region
* Investigate basic plasma processes occuring in the near-Earth solar wind
* Provide baseline ecliptic plane observations to be used in heliospheric latitudes from ULYSSES.
