Black Knight Satellite

Nov 11, 2015
Any theories? Note any proposed theory must account for the following:

  1. According to monitoring agencies around the world, The Black knight satellite has been transmitting radio signals for over 50 years now.
  2. The US and Soviet Union have shown particular interest in this “unidentified space object”
  3. Rumors are that it was Nikola Tesla the first man to “intercept” a signal from the black knight satellite in 1899 after building a high-voltage radio device in Colorado Springs.
  4. Since the 1930′s Astronomers worldwide have been reporting strange radio signals which allegedly come from the “Black Knight”.
  5. In 1957, Dr. Luis Corralos of the Communications Ministry in Venezuela photographed it while taking pictures of Sputnik II as it passed over Caracas.
  6. The story of the Black Knight made its media debut in the 1940′s when the St. Louis Dispatch and The San Francisco Examiner wrote about the “Satellite” on May 14th 1954.
  7. The Time Magazine wrote about the Black Knight Satellite on the seventh of March, 1960.
  8. In 1957, an unknown “object” was seen “shadowing” the Sputnik 1 Spacecraft. According to reports, the “unidentified object” was in Polar orbit.
  9. In 1957. The United States nor the Russians possessed the technology to maintain a spacecraft in Polar Orbit.
  10. The first Polar orbiting satellite was launched in 1960.
  11. Polar orbits are often used for earth-mapping, earth observation, capturing the earth as time passes from one point and reconnaissance satellites. This would put the Black Knight in the category of an observational Satellite.
  12. In the 1960′s the Black Knight satellite was located once again in Polar Orbit. Astronomers and Scientists calculated the object’s weight to be over 10 tons which would be at that time the Heaviest Artificial Satellite to orbit our Planet.
  13. The Black Knight’s orbit was unlike any other object orbiting Earth.
  14. The Grumman Aircraft Corporation gave much importance to this mysterious “Satellite”, On September 3, 1960, seven months after the satellite was first detected by radar, a tracking camera at Grumman Aircraft Corporation’s Long Island factory took a photograph of the Black Knight satellite.
  15. The Grumman Aircraft Corporation formed a committee to study the data received from the observations made but nothing was made public.
  16. In 1963, Gordon Cooper was launched into space. On his last orbit, he reported seeing a glowing green object in front of his capsule in the distance moving towards his Spacecraft. The Muchea tracking station, in Australia, which Cooper reported the object to, picked up this Unidentified object on Radar travelling East to West.
  17. It was the Ham Radio operator who apparently decoded a series of signals received from the UFO Satellite and interpreted it as a star-chart centered on the Epsilon Bootes Star System.
  18. According to the decoded message, the Black Knight satellite originated from the Epsilon Bootes Star System 13.000 years ago.
  19. On August 23, 1954 the technology magazine Aviation Week and Space Technology released a story about the Black Knight Satellite that angered the Pentagon who were trying to keep the information secret.
  20. NASA has released official images which apparently show the Black Knight Satellite.

I wasn't familiar with this one but anything associated with Tesla usually catches my attention. After poking around, I'm going to go with lost NASA blanket from STS-88.
No, it goes back to the 1930's way before anyone could put anything into orbit. Your proposal doesnt even begin to explain it. Try again. How come it was originally detected in the 1930's ?

No, you'll have to go to the Library and search old Astronomy papers frmo 1930's.

Not everything useful is online....

Also try St. Louis Post Dispatch and the San Francisco Examiner of 1954.

In 1963, astronaut Gordon Cooper reported seeing a greenish UFO during his 15th orbit on board Mercury 9. It was witnessed on the radar screens by approximately 100 people at NASA's Muchea Tracking Station near Perth, Australia. I have no idea if the Mercury mission trasnscripts are available online

Also Associated Press. "Dark Satellite Remains Mystery; Unclaimed by All." The Southeast Missourian. 11 Feb. 1960, Newspaper: 14.

In the case of a notable persons like Tesla, though, just about everything is online.

I usually like to want to believe but in this case the more details that are added the more it seems like that is an urban legend that is growing because it is on the internet.

Yes, Tesla picked up something from space, likely pulsar signals. Those 1954 articles? They are based on claims by Donald Keyhoe, a writer of UFO related articles & books promoting his books. Nobody else was used as source for the articles, they were just the claims of Keyhoe. The 1960 mystery? Reported on by Time magazine as being debris from the Discoverer satellites. The Time article used the phrase "dark satellite". Even the phrase "black knight satellite" can be traced back to a series of UK satellite launches in the 50's & 60's named "Black Knight".

There are definitely some UFO (actual UFO, not the 'little green men' type UFO) stories that can't be explained, the Black Knight Satellite though has more explanations than it does mysteries.

Debris could not possibly stay in orbit for so long withourt power to keep it up there as the orbit decayed. Its just not credible. Especially at such a low altitude. It really is simply not feasible.

and the 100 people at the NASA tracking station that saw the radar track ?

Just because a satellite is unclaimed doesn't mean it doesn't belong to the country claiming to have no knowledge of it. But that picture is clearly space junk.

More interested in these signals supposedly intercepted and how (if) it was every determined to be coming from orbit?


Keep cool, its Sci-fi dude

I saw that, it could be a chunk of an asteroid, or funky space junk orbiting around the earth. It is fascinating...

I have heard of this object a few times in a couple of different UFO type shows, and the last time was quite recent. No I will also bring up in the 80's, I dated a woman whom had a relative of her that was a scientist/engineer that worked for NASA. That relative of hers and I talked about many different events and matters that were unexplained and just unknown. This object was one of the topics we had talked about and it was quite interesting. I believe it to be true and believe it to still be active. I also believe our government will never ever make it public or report on it.
