The Black Knight satellite conspiracy theory claims that there is a spacecraft in near-polar orbit of the Earth that is of extraterrestrial origin, and that NASA is engaged in a cover-up regarding its existence and origin.[2][3] This conspiracy theory combines several unrelated stories into one narrative.[4][5]

 

A 1998 NASA photo is believed by some to show the Black Knight satellite, but NASA has stated that this is likely space debris, specifically a thermal blanket lost during an EVA mission.

The origin of the Black Knight legend is often "retrospectively dated" back to natural extraterrestrial repeating sources supposedly heard during the 1899 radio experiments of Nikola Tesla[6][7] and long delayed echoes first heard by amateur radio operator Jรธrgen Hals in Oslo, Norway, in 1928.[8] Brian Dunning of the Skeptoid podcast attributes Tesla's 1899 radio signals to pulsars, which were not identified until 1968.[5]
