Project Overview

Introduction Blank image that forces spacing between columns.

WIND was launched on November 1, 1994 and is the first of two NASA spacecraft in the Global Geospace Science initiative and part of the ISTP Project. WIND will be positioned in a sunward, multiple double-lunar swingby orbit with a maximum apogee of 250Re during the first two years of operation. This will be followed by a halo orbit at the Earth-Sun L1 point.

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.
