"Vidicon-tube cameras were first deployed in space as part of the "Seliger" system, built by I.L. Valik at the Leningrad Scientific Research Institute of Television (NII-380). It was installed on the Vostok manned spacecraft. Based on an earlier videophone project, it used two cameras, with persistent LI-23 iconoscope tubes. It output a 50 KHz video signal (10 frames per second, 100 lines per frame) on an 83 MHz carrier.
"The Seliger system was tested during the 1960 launches of the Vostok capsule (codenamed Object-K). Sputnik-5, also called Spaceship Sputnik-2, containing the space dogs Belka and Strelka, whose images are often mistaken for the dog Laika. In 1961, Iurii A. Gagarin became the first man in space, on Vostok-1. Vostok-2 and thereafter used an improved 400-line television system. NII-380 retained control of Earth-orbiting imaging systems, including cosmonaut video systems, Molniia and early Meteor cloud cameras, and the phototelevision system on early Zenit spy satellites. However around this time, Riazanskii's bureau was given control of all deep-space imaging systems. "
