Some Discoveries And/or Contributions To Science By The WIND Spacecraft

  1. Observation of relationship between large-scale solar wind-magnetosphere interactions and magnetic reconnection at the terrestrial magnetopause .
  2. First statistical study of high frequency (≥1 kHz) electric field fluctuations in the ramp of interplanetary (IP) shocks . The study found that the amplitude of ion acoustic waves (IAWs) increased with increasing fast mode Mach number and shock compression ratio. They also found that the IAWs had the highest probability of occurrence in the ramp region.
  3. Observation of the largest whistler wave using a search coil magnetometer in the radiation belts .
  4. First observation of shocklets upstream of a quasi-perpendicular IP shock .
  5. First simultaneous observations of whistler mode waves with electron distributions unstable to the whistler heat flux instability .
  6. First observation of a solitary wave at an IP shock with an amplitude exceeding 100 mV/m .
  7. First observation of electron-Berstein-like waves at an IP shock .
  8. First observation of the source region of an IP Type II radio burst .
  9. First evidence for Langmuir wave coupling to Z-mode waves .
  10. First evidence to suggest that the observed bi-polar ES structures in the shock transition region are consistent with BGK modes or electron phase space holes .
  11. First evidence of a correlation between the amplitude of electron phase space holes and the change in electron temperature .
  12. First evidence of three-wave interactions in the terrestrial foreshock using bi-coherence .
  13. First evidence of proton temperature anisotropy constraints due to mirror, firehose, and ion cyclotron instabilities .
  14. First evidence of Alfvén-cyclotron dissipation .
  15. First (shared with STEREO spacecraft) observation of electron trapping by a very large amplitude whistler wave in the radiation belts (also seen in STEREO observations ).
  16. First observation of Langmuir and whistler waves in the lunar wake .

Famous quotes containing the words discoveries, science and/or wind:

    “Astronomy is perhaps the science whose discoveries owe least to chance, in which human understanding appears in its whole magnitude, and through which man can best learn how small he is.”
    —G.C. (Georg Christoph)

    “The science hangs like a gathering fog in a valley, a fog which begins nowhere and goes nowhere, an incidental, unmeaning inconvenience to passers-by.”
    —H.G. (Herbert George)

    “Being a Jew is like walking in the wind or swimming: you are touched at all points and conscious everywhere.”
    —Lionel Trilling (1905–1975)
