From the 15-ton Black Knight satellite to French government certification... UFO mysteries that shook the world

From mysterious satellites discovered during the space race of the Cold War era to unidentified flying objects that national agencies have begun to investigate, mysterious phenomena targeting the entire world have been compiled.

The vanished 15-ton 'Black Knight satellite', possibility of reappearance in 2030

In February 1960, during the space war of the US-Soviet Cold War era, an unidentified satellite was discovered, causing confusion. This object, known as the 'Black Knight satellite', was expected to have a weight of approximately 15 tons, far exceeding the maximum weight of 500kg that could be launched with the technology of that time. Furthermore, its operating speed was about 2 to 3 times faster than the latest satellite at the time, Sputnik 2, and it exhibited the characteristic of operating in the opposite direction of Earth's satellites without being constrained by Earth's gravity.

The Black Knight satellite, which disappeared three weeks after its discovery, was captured again in January 1980. At that time, the United States announced that this satellite was debris from a failed launch of the Discoverer satellite, but according to detailed photographs released by NASA in 1998, its appearance was not that of simple debris but took the form of a sophisticated satellite. Some astronomers are speculating that this satellite will reappear around 2030 after analyzing the records of the Black Knight satellite.

Shapes captured on Mars and the reality of KGB classified videos

Mysterious traces have also been reported during the process of Mars exploration. In 2015, while the Mars exploration robot Curiosity was filming a canyon, a shape similar to a female figure with two arms, a long head, and a chest was captured. According to an alien tracking site, the height of this figure is estimated to be about 8–10cm. Meanwhile, among the videos released through YouTube in 2011, a pattern similar to the emblem of the Soviet KGB appeared, and classified videos presumed to be kept by the KGB were mentioned. It is said that these videos contain scenes of UFOs landing or the appearance of aliens.

Chilean Navy radar and records from the French National Agency for Space Research

Cases of unidentified flying objects involving national agencies have also been confirmed in South America and Europe. In 2014, an officer belonging to the Chilean Navy captured a wingless disc-shaped flying object through a helicopter's infrared camera. The object was not captured on military radar, but video analysis showed no signs of manipulation. CEFAA, the UFO investigation agency of the Chilean government, concluded that it was an unidentified flying object after an investigation lasting about two years.

In 1981, in the Provence region of France, a farmer witnessed a disc-shaped object about 2 meters in diameter land and then take off. As a result of an investigation by a research institute under the French national space agency at the time, the soil at the point where the flying object landed was scorched by heat of 300–600 degrees Celsius, and the chlorophyll of plants had decreased by 30–50%. Additionally, traces of approximately 4–5 tons of mechanical pressure were also discovered, and officials at the time mentioned this as clear evidence of a UFO.
