Zond 1

Zond 1, a member of the Soviet Zond program, was the second Soviet research spacecraft to successfully reach position Venus. However, like the previous "success," the Venera 1, communications from the satellite failed before it reached Venus.

The spacecraft, a Venera 3MV-1, was launched on April 4, 1964 from Tyuratam, communications failed by May 14, and it achieved orbit around the sun 100,000km from Venus on July 14 of that year.
