The Black Knight Satellite is the popular designation for an alleged artificial object of unknown or extraterrestrial origin claimed by some UFO researchers and conspiracy theorists to be in near-polar orbit around Earth — and to have been there for approximately 13,000 years. The theory holds that this ancient alien probe has been transmitting signals toward Earth since at least the late 19th century, that it has been observed and photographed by NASA during multiple space missions, and that governmental and space agency authorities are actively concealing its nature and origin.
Black Knight Satellite — Cultural Impact and Media Legacy:
The Black Knight satellite is notable in this context because the conventional explanations for its component events are particularly strong — and yet the legend continues to grow precisely because it has crossed from UFO subculture into mainstream internet culture, where it reproduces through sharing rather than through critical evaluation.
Black Knight Satellite — Donald Keyhoe and the 1954 Newspaper Claims:
In 1954, several American newspapers — including the St. Louis Post-Dispatch and the San Francisco Examiner — published stories based on claims by UFO researcher and retired U.S. Marine Corps Major Donald Keyhoe that the United States Air Force had detected one or two artificial satellites orbiting Earth.
