Kosmos 472

Kosmos 472 (Russian: Космос 472 meaning Cosmos 472), known before launch as DS-P1-Yu No.52, was a Soviet satellite which was launched in 1972 as part of the Dnepropetrovsk Sputnik programme. It was a 250-kilogram (550 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 472 was successfully launched into low Earth orbit on 25 January 1972, with the rocket lifting off at 11:15:01 UTC.[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, it was assigned its Kosmos designation, and received the International Designator 1972-004A.[4] The North American Aerospace Defense Command assigned it the catalogue number 05804.

Kosmos 472 was the fiftieth of seventy nine DS-P1-Yu satellites to be launched,[1] and the forty-fifth of seventy two to successfully reach orbit.[5] It was operated in an orbit with a perigee of 195 kilometres (121 mi), an apogee of 1,417 kilometres (880 mi), 81.9 degrees of inclination, and an orbital period of 101 minutes.[1][6] It remained in orbit until it decayed and reentered the atmosphere on 18 August 1972.[6]
