Venera 3MV-1

Zond 1, a member of the Soviet Zond program, was the second Soviet research spacecraft to successfully reach position Venus. A slow leak from a cracked sensor window caused the spacecraft to depressurize. An ill-timed command from ground control turned on its radio system while there was still a rarefied atmosphere inside, causing the electronics to short out by corona discharge. Communication was subsequently maintained via the transmitter in the landing capsule, and space radiation and atomic-hydrogen spectrometer measurements were performed. From http://nssdc. ... From http://nssdc. ... The name Zond (meaning probe in Russian) is the name given to two series of Soviet unmanned space missions from 1964 to 1970 to gather information about nearby planets and test spacecraft. ...


Zond-1 was designed to carry a 90 cm spherical landing capsule to Venus. It contained experiments for chemical analysis of the atmosphere, gamma-ray measurments of surface rocks, a photometer, temperature and pressure gauges, and a motion/rocking sensor in case it landed in water.


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. April 4 is the 94th day of the year in the Gregorian calendar (95th in leap years). ... 1964 was a leap year starting on Wednesday (link will take you to calendar). ...

Zond program - Wikipedia, the free encyclopedia (376 words)
The name "Zond" (meaning "probe" in Russian) is the name given to two series of Soviet unmanned space missions from 1964 to 1970 to gather information about nearby planets and test spacecraft.
After two failures, Zond 3 was sent on a test mission, photographing the far side of the Moon (only the second spacecraft to do so) and continuing out to the orbit of Mars in order to test telemetry and spacecraft systems.
The unmanned circumlunar Zond 5 flight in September 1968 was part of the reason NASA flew Apollo 8 to the moon in December 1968 instead of the Earth orbital test which had been planned, because the CIA believed the Russians were planning a human flight next.
