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-2 carried a phototelevision camera of the same type later used to photograph the Moon on Zond 3. The camera system also included two ultraviolet spectrometers. As on Mars 1, an infrared spectrometer was installed to search for signs of methane on Mars. Mars 3MV-4A Zond 3, a member of the Soviet Zond program, was the first Zond spacecraft to successfully complete its mission (a Lunar flyby) and took a number of amazing photographs for its time, though it is believed that it was initially intended to fly by Mars with Zond... Mars 1 (1962 Beta Nu 1) was an automatic interplanetary station launched in the direction of Mars on November 1, 1962, the first of the Soviet Mars probe program, with the intent of flying by the planet at a distance of about 11,000 km. ...

Zond 2 also carried six PPTs that served as actuators of the attitude control system. They were the first PPTs used on a spacecraft. The PPT propulsion system was tested during 70 minutes.

Zond 2, a Mars 3MV-4A craft, was launched on November 30, 1964. During some maneuvering in early May, 1965, communications were lost. Running on half power due to the loss of one of its solar panels, the spacecraft flew by Mars on August 6, 1965 at 5.62 km/s, 1,500 km away from the planet.
