HAARP (High Frequency Active Auroral Research Program) is a former research program and facility located in Gakona, Alaska, that was used to study the Earth’s ionosphere, a part of the upper atmosphere that can reflect radio signals. The facility was equipped with a high-frequency radio transmitter and a large array of antennas, which were used to study the ionosphere and its interactions with the Earth’s magnetic field and the solar wind.
HAARP was designed to allow researchers to temporarily alter the ionosphere, creating an artificial “mirror” in the sky to reflect radio signals over long distances. This made it possible to study the ionosphere in greater detail, as well as to understand its potential uses for communication and navigation.
The program was a collaborative effort between the U.S. Air Force, the U.S. Navy, and the University of Alaska, and was funded by the U.S. government. However, it faced criticism from some individuals who believed that it was being used for military purposes or for secretly manipulating the weather.
HAARP was officially shut down in 2013, and the facilities and equipment were eventually turned over to the University of Alaska Fairbanks. Today, the HAARP facilities are used primarily for educational and research purposes.
