Summary:
The antennas belong to the High Frequency Active Auroral Research Program (HAARP), a former U.S. military facility near the hamlet of Gakona. The array will beam 2.1 megawatts of radio energy into the ionospherethe region that starts at 100 kilometers above the ground, where solar photons and charged particles crash into Earths atmosphere. There the radio signals will excite electrons and turn them into waves of relatively hot ionized gas, or plasma, in a narrow slice of sky. The hope is to better understand activity that hampers satellites as well as some elusive features of radio wave physics.
