First soviet Planetary Radar (built in 1960), which sent the message in 1962. Yevpatoria, Crimea

In 1962 a radio message in Morse code was transmitted from the Evpatoria Planetary Radar (EPR) and directed to the planet Venus.[1][2] The word "MIR" (Russian: Мир meaning both "peace" and "world") was transmitted from the EPR on November 19, 1962, and the words "LENIN" (Russian: Ленин) and "SSSR" (Russian: СССР, the abbreviation for the Soviet Union (Союз Советских Социалистических Республик)) on November 24, 1962, respectively. All three words were sent using the Morse code.[3] In Russian, this letter is called Radio Message "MIR, LENIN, SSSR". This message was the first radio broadcast for extraterrestrial civilizations in the history of mankind.[1] It was also used as a test for the radar station (but was not used for measuring the distance to Venus because for distance measurements the EPR uses a coherent waveform with frequency manipulation). The signal reflected from the surface of Venus and was received 4 minutes 32.7 seconds (Nov 19) and 4 minutes 44.7 seconds (Nov 24) later.

Now this radio message is flying to the star HD 131336 [4] in the Libra constellation (the famous star Gliese 581, the addressee of A Message From Earth and Hello From Earth, is also located in the Libra).
