HIPAS Observatory

HIPAS Observatory is a research facility northeast of Fairbanks, Alaska, equipped with radio transmitters and specialized equipment to study the ionosphere. The installation spans a large site and was designed to examine how radio waves interact with the atmosphere in the Arctic region.

The facility began operation in 1986 under UCLA's plasma physics laboratory and investigated radio wave phenomena in the atmosphere. Operations ceased in 2007 after decades of scientific activity in this remote region.

Scientists at HIPAS Observatory investigated fundamental questions about radio communications and atmospheric phenomena in the Arctic environment.

The site is located in a remote area and is difficult to reach, so it makes sense to check access conditions beforehand. Anyone wanting to visit should contact local institutions in Fairbanks, as access may be restricted.

The facility once housed an unusual 2.8-meter telescope that used a rotating mercury mirror as its reflecting surface. This innovative design enabled laser experiments that were not possible with conventional telescopes.
