Zond 2 was a Soviet space probe , a member of the Zond program , and was the sixth Soviet spacecraft to attempt a flyby of Mars . [1] [2] (See Exploration of Mars ) [3] It was launched on November 30, 1964 at 13:12 UTC onboard Molniya 8K78 launch vehicle from Baikonur Cosmodrome , Kazakhstan, USSR. The spacecraft was intended to survey Mars but lost communication before arrival.
History
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.
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 kilometres per second (3.49 mi/s) , 1,500 kilometres (930 mi) away from the planet.
