Kosmos 23 (Russian: Космос 23 meaning Cosmos 23), also known as Omega No.2, was a satellite which was launched by the Soviet Union in 1963.

[3] 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.

The kinetic energy of the flywheels was dampened by using electromagnets that produced torque by interacting with the Earth's magnetic field.

Kosmos 23 may have also carried the first Soviet meteorological scanning infrared radiometer to obtain crude nighttime pictures of the cloud cover of the Earth.

[5] The launch occurred at 13:55 GMT on 13 December 1963, and resulted in the successful insertion of the satellite into a low Earth orbit.
