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.
Launch
Kosmos 455 was successfully launched into low Earth orbit on 17 November 1971, with the rocket lifting off at 11:09:48 UTC. The launch took place from Site 133/1 at the Plesetsk Cosmodrome, and used a Kosmos-2I 63SM carrier rocket.
Orbit
Upon reaching the orbit, it was assigned its Kosmos designation, and received the International Designator 1971-097A.
Kosmos 455 was the forty-seventh of seventy nine DS-P1-Yu satellites to be launched, and the forty-second of seventy two to successfully reach orbit. 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. It remained in orbit until it decayed and re-entered the atmosphere on 9 April, 1972.
