Researchers will use this event to study the mechanisms in the ionosphere that result in optical emissions. Additionally, they will attempt to determine whether specific plasma waves—gas so hot that it knocks electrons out of atoms—amplify other very low frequency waves and study how satellites can detect and avoid collisions by using these specific plasma waves.
Similar to how solar energy produces a natural aurora, HAARP produces airglow by using intermittent bursts of high-frequency radio waves to excite electrons in earth's ionosphere. With 180 high-frequency antennas arranged in a phased array over 33 acres, HAARP's Ionospheric Research Instrument has the capacity to radiate 3.6 megawatts into the ionosphere and upper atmosphere.
