Kosmos 523 (Russian: Космос 523 meaning Cosmos 523), known before launch as DS-P1-Yu No.63, was a Soviet satellite which was launched in 1972 as part of the Dnepropetrovsk Sputnik programme. It was a 325-kilogram (717 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests.[1]
Kosmos 523 was successfully launched into low Earth orbit at 11:30:00 UTC on 5 October 1972.[2] The launch took place from Site 133/1 at the Plesetsk Cosmodrome,[3] and used a Kosmos-2I 63SM carrier rocket. Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1972-078A.[4] The North American Aerospace Defense Command assigned it the catalogue number 06222.
Kosmos 523 was the fifty-seventh of seventy nine DS-P1-Yu satellites to be launched,[1] and the fifty-first of seventy two to successfully reach orbit.[5] It was operated in an orbit with a perigee of 264 kilometres (164 mi), an apogee of 450 kilometres (280 mi), 71 degrees of inclination, and an orbital period of 91.7 minutes.[6] It remained in orbit until it decayed and reentered the atmosphere on 7 March 1973.[6]
