Kosmos 485 ( Russian: Космос 485 meaning Cosmos 485), known before launch as DS-P1-Yu No.58, 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 485 was successfully launched into low Earth orbit at 11:04:58 UTC on 11 April 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 1972-028A. [4] The North American Aerospace Defense Command assigned it the catalogue number 05938.
Kosmos 485 was the fifty-second of seventy nine DS-P1-Yu satellites to be launched, [1] and the forty-seventh of seventy two to successfully reach orbit. [5] It was operated in an orbit with a perigee of 262 kilometres (163 mi), an apogee of 444 kilometres (276 mi), 70.9 degrees of inclination, and an orbital period of 91.6 minutes. [1] [6] It remained in orbit until it decayed and reentered the atmosphere on 30 August 1972. [6]
