Zond (
'probe' in
Russian) was the name given to two distinct series of Soviet robotic spacecraft launched between 1964 and 1970. The first series, based on the 3MV planetary probe, was intended to gather information about nearby planets.
The second series of test spacecraft was intended as a precursor to remote-controlled robotic circumlunar loop flights, using a stripped-down variant of Soyuz spacecraft, consisting of the service and descent modules, but lacking the orbital module.
Two tortoises and other lifeforms aboard Zond 5 were the first terrestrial organisms to travel around the Moon and return to Earth.
The date on the pin is somewhat misterious, as there two Zonds were launched in 1967 -
"Zond-4A"
launched on September 28, 1967. Its mission was to test on-board equipment in a flyby of the Moon. During the launch, one of the six engines of the launch vehicle
first stage
failed. The rocket was blown up at the 67th second of flight. The descent vehicle was returned to Earth by an emergency rescue system.
"Zond-4B"
launched on November 22, mission was the same. One of the four engines of the launch vehicle
second stage
did not gain the necessary thrust. The descent vehicle was returned to Earth by an emergency rescue system.
Most likely, some important event in Zond program took place on October 12, 1967.
