Kosmos 455 (Russian: Космос 455 meaning Cosmos 455), known before launch as DS-P1-Yu No.54, was a Soviet satellite which was launched in 1971 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]

Launch

Kosmos 455 was successfully launched into low Earth orbit on 17 November 1971, with the rocket lifting off at 11:09:48 UTC.[2] The launch took place from Site 133/1 at the Plesetsk Cosmodrome,[3] and used a Kosmos-2I 63SM carrier rocket.

Orbit

Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1971-097A.[4]

Kosmos 455 was the forty-seventh of seventy nine DS-P1-Yu satellites to be launched,[1] and the forty-second 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 468 kilometres (291 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 9 April 1972.[6]
