It’s an aerial field in Alaska it didn’t give birth to the cons of conspiracy theories conducts a series of experiments that include sending radio signals to the Moon and Jupiter and waiting pings back.

The High Frequency Active Auroral Research Program (HAARP) began a ten-day science campaign that lasted until October 28. On the agenda were 13 experiments that push the boundaries of what the plant can do. “The October research campaign is our largest and most diverse to date, with researchers and scientists collaborating from around the world,” said Jessica Matthews, HAARP’s program manager. let go.

HAARP consists of 180 high-frequency antennas, each 72 feet tall, spread over 33 acres near Gakona, Alaska. The research facility emits radio rays towards the Earth’s ionosphere, the ionized part of the atmosphere that is findings about 50 to 400 miles (80 to 600 kilometers) above the Earth’s surface. The ionosphere is filled with electrically charged particles that are the result of an explosion of solar energy. HAARP sends radio signals into the ionosphere and waits to see how they come back, in an attempt to measure disturbances caused by the Sun, among other things.

In a recent one experiment, known as the “Moon Bounce,” a group of researchers from NASA’s Jet Propulsion Laboratory, the Owens Valley Radio Observatory, and the University of New Mexico transmitted a signal from the HAARP antennas in Alaska to the moon, then waited to receive the reflected signal back at the observatories in California and New Mexico.

The purpose of the experiment is to study how the three facilities in Alaska, California and New Mexico can work together for future observations of near-Earth asteroids. The facility may be able to send a signal to an asteroid flying by Earth and receive a signal back that will provide clues to the composition of the space rock.

Another experiment sent a radio beam to Jupiter, which is currently about 600 million kilometers from Earth. The hope is that the beam will bounce off Jupiter’s ionosphere and then be received at a site in New Mexico.

The Jupiter experiment is led by the John Hopkins Applied Physics Laboratory and aims to provide a new way to observe the ionosphere of other planets. Considering how far Jupiter is from Earth, this experiment is a real test of HAARP’s signal transmission capabilities.

Another experiment is more on the artistic side. “Ghosts in the Air Glow” transmitted video, images, spoken word and sound art into the ionosphere and waited for the signal to bounce back to test the transition boundary of the atmosphere.

HAARP was originally a project US Air Force to study solar flares, which can disrupt Earth communications and electrical grid. But in 2015 The Air Force has decided that it is no longer interested in maintaining HAARPand ownership was transferred to the University of Alaska. While under the purview of the Air Force, HAARP inspired some wild conspiracy theories, including that its antennas were used to alter the weather, create deadly hurricanes, and even control minds.
