WIND is a NASA science spacecraft launched on November 1, 1994. The satellite is a spin stabilized cylindrical satellite with a diameter of 2.4 m and a height of 1.8 m.
It was deployed to study radio and plasma that occur in the solar wind and in the Earth’s magnetosphere before the solar wind reaches the Earth. The spacecraft’s original mission was to orbit the Sun at the L1 Lagrangian point, but this was delayed when the SOHO and ACE spacecraft were sent to the same location. WIND has been at L1 continuously since 2004, and is still operating as of March 18, 2014. WIND currently has enough fuel to last roughly 60 years at L1.
