Pin made in the Soviet Union about Kocmoc 23 (Kosmos 23). Kosmos 23, also known as Omega No.2, was a satellite which was launched by the Soviet Union in 1963.
Kosmos 23 was a test platform orbited by the Soviet Union for the purpose of evaluating electrotechnical systems later used to ensure the orientation and stabilization of weather satellites. Like its predecessor, Kosmos 14, the satellite was in the form of a cylinder, with two hemispherical ends, and was 1.8 metres (5 ft 11 in) long and 1.2 metres (3 ft 11 in) in diameter. Tests were made of power supplies that used solar cell batteries, and equipment on board monitored the operation of automatic devices that controlled the solar and chemical batteries.
