Wind

The Wind space probe studies plasma (ionized gas), particles and magnetic fields around the Sun. In addition, the space probe provides early warnings to Earth as to when intense solar storms might be directed its way. Wind makes 11 magnetic measurements a second and particle observations every three seconds. Wind aims to help improve our understanding of the physics involved in the relationship between the Earth and the Sun and has often worked together with the space probe ACE to do so. By continuing to monitor solar activity, the space probe can better forecast how solar phenomena affects Earth and when it might be hazardous. Over its lifetime, Wind has detected different kinds of electromagnetic waves, which is said to have opened up new areas of research. It’s estimated that Wind has enough fuel to continue operations until 2074.
