In 1998, during Space Shuttle mission STS-88, NASA astronauts photographed an unidentified object in polar orbit above Earth. The object was dark, irregular in shape, and did not correspond to any satellite on record — American, Soviet, or otherwise.
NASA's official explanation: a thermal blanket lost during an earlier mission.
Analysts and independent researchers have noted that the object's size, shape, and orbital trajectory do not align with that explanation. The photographs remain publicly available. The discrepancy has never been formally addressed.
What makes this case unusual is its historical dimension. Reports of an unidentified object in polar orbit predate the space age entirely. In the 1920s, amateur radio operators across multiple countries independently reported receiving unusual repeating signals of unknown origin. Nikola Tesla documented receiving anomalous repeating transmissions from space years before — transmissions he could not explain and never attributed to a natural source.
The object photographed in 1998 became known as the Black Knight Satellite. Whether it is debris, a misidentified object, or something without a current classification depends entirely on which evidence you examine — and which explanation you find credible.
NASA has not revisited the case.
