Observe the unperturbed solar wind that is about to impact the magnetosphere of Earth.
Wind solar wind data has been cited in more than 4,000 scientific publications.
Wind is a spin stabilized spacecraft launched with a Delta II rocket on Nov. 1, 1994. After several orbits through the magnetosphere, Wind was placed in a halo orbit around the L1 Lagrange point -- more than 200 Re upstream of Earth -- in early 2004 to observe the unperturbed solar wind that is about to impact the magnetosphere of Earth.
Wind, together with Geotail, Polar, SoHO and Cluster, constitute a cooperative scientific satellite project designated the International Solar Terrestrial Physics (ISTP) program that aims at gaining improved understanding of the physics of solar terrestrial relations.
The primary science objectives of the Wind mission are:
- Provide complete plasma, energetic particle and magnetic field for magnetospheric and ionospheric studies.
- Investigate basic plasma processes occurring in the near-Earth solar wind.
- Provide baseline, 1 AU, ecliptic plane observations for inner and outer heliospheric missions.
