Solar Weather Observer

Our solar system is filled with a fierce wind of charged particles blowing from the sun and deep space. When the solar wind penetrates our magnetosphere, it can knock out satellites and even land-based electrical systems. GEOTAIL was sent up to observe the turbulent wake that Earth’s magnetosphere pulls behind it and how the solar wind penetrates through. By keeping an eye on the weather in space, GEOTAIL helps protect those of us here on Earth from unexpected disruptions to our vital communications and power networks.
