Kosmos 458 (Russian: Космос 458 meaning Cosmos 458), known before launch as DS-P1-Yu #53, was a Soviet satellite which was launched in 1971 as part of the Dnepropetrovsk Sputnik programme. It was a 325-kilogram (720 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 458 was successfully launched into low Earth orbit on 29 November 1971, with the rocket lifting off at at 10:09:56 GMT.[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 1971-101A.[4] The North American Aerospace Defense Command assigned it the catalogue number 05623.
Kosmos 458 was the forty-eighth of seventy nine DS-P1-Yu satellites to be launched,[1] and the forty-third of seventy two to successfully reach orbit.[5] It was operated in an orbit with a perigee of 266 kilometres (165 mi), an apogee of 473 kilometres (294 mi), 70.9 degrees of inclination, and an orbital period of 91.9 minutes.[1][6] It remained in orbit until it decayed and reentered the atmosphere on 20 April 1972.[6]
