By 1951, word came that the then surplus Scribner Air Base was being considered as the site of a proposed United States Air Force Academy. This did not happen, however, the U.S. Air Force acquired 136 acres (0.55 km 2) for installation of an ionosphere sounding station. This High Frequency radio receiver site did operate and is in fact still in ...
Needles from the West Ford project compared to a stamp. Project West Ford (also known as Westford Needles and Project Needles) was a test carried out by Massachusetts Institute of Technology's Lincoln Laboratory on behalf of the United States military in 1961 and 1963 to create an artificial ionosphere above the Earth.

Main gases of the ionosphere (about 50 km; 31 miand above on this chart) vary considerably by altitude. The F layer or region, also known as the Appleton–Barnett layer, extends from about 150 km (93 mi) to more than 500 km (310 mi) above the surface of Earth. It is the layer with the highest electron density, which implies signals penetrating ...
(The Center Square) – West Point Military Academy and the Air Force Academy have both ended their “Diversity and Inclusion Studies” minors. As late as Jan. 8, West Point, based in New York ...
SpaceX’s rocket explosion in November 2023 created a massive hole in the Earth's ionosphere, providing scientists with a rare opportunity to study its effects.
Balloons cannot reach it because the air is too thin, but satellites cannot orbit there because the air is too thick. Hence, most experiments on the ionosphere give only small pieces of information. HAARP approaches the study of the ionosphere by following in the footsteps of an ionospheric heater called EISCAT near Tromsø, Norway. There ...
USA-221, also known as FalconSat-5, is an American military minisatellite, which was launched in 2010. The fifth FalconSat spacecraft to be launched, it carries four technology development and ionospheric research experiments. The satellite was constructed and is operated by the United States Air Force Academy.
