Venera 1The Soviet Union launches Venera 3, its third attempt to send a spacecraft to Venus. Intended to land on the surface of what is still thought of as a near-twin of Earth, Venera 3’s landing capsule does indeed enter the Venusian atmosphere in March 1966, though the capsule loses contact with Earth and goes silent before ever hitting the surface of Venus. Venera 3 may be the first human-made object ever to arrive on another planet, but no telemetry exists to prove that it arrived in one piece.
