What is the Black Knight satellite? It is a mysterious satellite, of unknown origin, discovered in 1960 which shadowed Sputnik. It is believed to have been of extraterrestrial origin, and signaled back old radio waves from the 1920s and 1930s before it disappeared.
HISTORICAL SPACE FREQUENCIES. The first satellite to orbit the Earth was Sputnik 1, launched by the Soviets in October 1957. It carried two radio beacons on frequencies of 20.005 and 40.01 MHz. The Soviets continued to use frequencies around 20 MHz and even some around 15 MHz for many subsequent missions.
