Black Knight satellite conspiracy theory

Record	OBS-0007
Category	Space/NASA
Status	DEBUNKED
Summary	The Black Knight satellite conspiracy theory claims that an extraterrestrial spacecraft has been orbiting Earth for about 13,000 years, with NASA covering up its existence. Proponents point to a 1998 NASA photo as evidence, but the photo is identified as space debris, specifically a thermal blanket lost during the STS-88 mission. The theory is a conflation of unrelated stories, including Nikola Tesla's 1899 radio signals and 1954 reports of satellites.
Origin	The legend dates back to the late 19th and early 20th centuries, with Tesla's 1899 radio experiments and 1928 long delayed echoes, but the specific 'Black Knight' narrative emerged later, combining these with 1950s satellite reports and the 1998 STS-88 photo.
Claimed	An extraterrestrial satellite has been in polar orbit around Earth for about 13,000 years. NASA is covering up the satellite's existence and origin. A 1998 NASA photo from STS-88 shows the Black Knight satellite. Nikola Tesla's 1899 radio signals were from the Black Knight satellite. The U.S. Air Force detected two unknown satellites in 1954, before any country could launch satellites.
Evidence / consensus	NASA and space experts identify the 1998 photo as a thermal blanket lost during STS-88. The story is a jumble of unrelated events, with no evidence of an ancient alien satellite. Tesla's signals are attributed to pulsars, and the 1954 reports are unverified.

> OBSERVER NOTE:
A classic case of myth-making from disparate fragments. The 1998 photo is mundane debris, yet the narrative persists. No physical evidence supports the ancient satellite claim.
